Modern computers enable you to install two or more operating systems on a single machine and use those operating systems independently. This configuration is known as dual-boot or multi-boot. The most popular combination of dual-boot system is Microsoft Windows and Linux operating systems. In order to continue Linux installation on a Windows machine, you are required to create a /boot partition using the free disk space available on your hard drive. You are highly recommended to halt Linux installation process while creating space for the /boot partition. However, it may render your Windows hard drive partition inaccessible and cause serious partition loss. In such circumstances, you need to go for Partition Recovery Software to retrieve inaccessible and lost hard drive partitions.

In order to illustrate this problem, consider the underwritten scenario:

You use a Microsoft Windows installed machine that has two partitions- one boot partition and one data partition.

You run the Setup of Linux operating system to install it on free hard drive space.

You abort Linux installation process when it creates /boot partition for the Linux operating system.

You boot your computer with Microsoft Windows operating system and find out that your data partitions is not accessible.

Or

You are able to access the data partition, but if you use a tool that accesses information of partitions, it displays wrong information about the Windows partitions.

Root of the problem

The problem generally occurs due to corruption of MBR (Master Boot Record) partition table, when you abort installation process of Linux operating system. Hard drive errors might have been introduced by an interrupted installation of Linux operating system.

Resolution

In order to Recover Partition in such situations, you can try out the below steps:

Remove and recreate the damaged Windows partitions, if you have an updated and valid backup in place.

If the backup is not updated or is unavailable, you can opt for third party applications to recover lost or damaged hard drive partitions.

The Partition Recovery Software are suitable for virtually every partition loss situation in Microsoft Windows. They deploy advanced scanning techniques to efficiently handle partition loss and ensure absolute Windows Data Recovery. With simple and rich graphical user interface and non-destructive nature, these applications are totally easy and safe to use.

Stellar Data Recovery Software recovers lost, corrupted, damaged, inaccessible, or deleted Windows partitions. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000 operating systems. It salvages NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions.

Are you unable to boot your Windows 7 or Windows Vista operating system-based computer, after making it dual-boot with an earlier version of Windows operating system? Do you encounter error when your system tries to read disk? This behavior of Windows may occur due to various compatibility issues and make your system unusable. At this point, you can not access your hard drive partitions and encounter partition loss situations. In order to recover lost partitions in such circumstances, Windows Data Recovery is required.

As a practical example, you may come below issues after installing an earlier version of MS Windows on a Windows Vista or Windows 7-based machine in dual-boot configuration:

Windows Vista does not boot after making your system dual-boot. Only earlier version of Windows boots up.

When you install an extra instance of Windows XP on a system, which has Windows Vista and Windows XP in dual-boot configuration, the below error message occurs.
“Disk read error has occurred.”

This behavior make your system inaccessible. To recover lost partitions in such cases, it becomes essential to find the cause of this problem and perform Windows Data Recovery by sorting it out.

Reason

This behavior of Windows operating system occurs as earlier versions of MS Windows are not compatible with Windows Vista boot method. Vista employs a new BCD (Boot Configuration Database) store. The BCD includes a boot menu and the information about the operating system, which are installed on your computer. Thus, the Boot.ini file which is from earlier version of Windows can not be used for booting up Windows Vista.

Resolution

You can try out the following things to work around this problem:

Use the Bootsect.exe for restoring Windows Vista Master Boot Record (MBR) and boot code, which transfers control to Windows Boot Manager (WBM) program.

Use Bcdedit.exe for creating a manual entry in BCD Boot.ini file in earlier version of Windows.

Reboot your system.

If the above method does not work, you need to format your hard drive and reinstall Windows Vista. In this case, you will lose all your hard drive partitions and need to Recover Partitions.

The make it quite easy to retrieve lost hard drive partitions. The software are able to handle all types of partition loss situations, using advanced scanning methods.

Stellar Phoenix Windows Data Recovery is the best made software that provides assured recovery of lost Windows partitions. It recovers FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000.

“Boot Disk failure” Or

“Operating System Not Found”

This behavior of Windows takes place when the hard drive is detected by BIOS (Basic Input Output System) but operating system doesn’t load. The system might get stuck on the second screen during the boot process and operating system may refuse to load. These circumstances could be really troublesome as there are very few troubleshooting options available to resolve them. There could be several reasons behind Windows bootup problems. The most common ones are as follows:

Corrupted Boot Loader: If you are working on a dual boot system, there are strong chances of boot loader corruption. For instance, if you are using Windows XP and Linux using LILO (LInux LOader) as boot loader and LILO gets damaged, you could not boot your system using either operating system. MBR Corruption: This problem could also occur due to corrupted MBR (Master Boot Record). It is the main program that is used for bootstrapping operating system, after BIOS executes the machine code instructions. Boot Sector Virus: The most probable reason of this behavior of Windows could be a boot sector virus. You can confirm it by connecting your hard drive to another computer and then scanning it using good antivirus software.

In either of these situations, the only option you have to fix the problem is to install a fresh copy of damaged system tool either it is boot loader or MBR. You can achieve this by recreating the partition structure, formatting the Windows partition and reinstalling the Windows operating system. It will fix all the disk related logical errors. But it also has a downside, recreating the partition structure erases the existing partition schema and thus all the underlying data goes missing. It puts you in immediate need of Partition Recovery. Partition Recovery is the way out of scanning your affected hard drive and then retrieving your lost partitions and data from them.

Partition Recovery is best possible through powerful Partition Recovery Software such as Stellar Phoenix Windows Data Recovery. Stellar Phoenix Windows Data Recovery is advanced Partition Recovery Software to achieve efficient Windows Partition Recovery. It is capable of retrieving data in all logical data loss situations. The e-mail recovery, disk cloning, read- only conduct, influential scanning mechanisms and live update are some major features which make this software world class. This outstanding tool is compatible with Windows Vista, XP, 2003 and 2000.

When you come across any error message during the Microsoft Windows Vista upgrade installation, rollback phase might be either successful or unsuccessful.

Successful rollback

If rollback phase completes successfully, you could start your Microsoft Windows XP on the system. Rollback procedures restores personal data files to original location on hard drive. After successful rollback, go through underwritten steps:

Ensure that personal data files are on correct location. If these files are missing, find them in following folders:

\$WINDOWS.~Q\DATA\Documents and Settings\Username

$INPLACE.~TR\Machine\Data\DATA\Documents and Settings\Username

\Users\Username

Check setup log files to consider reason of installation failure.

Unsuccessful rollback phase

If the rollback phase does not complete successfully, you might encounter any of the following things:

Your system does not boot up and you come across an error message while trying to run your system.

You get the “Rollback Setup” error message each time when you attempt to boot your system.

If you attempt to start your previous operating system installation, you come across error message, which resembles the below error message:

Windows could not start because the following file is missing or corrupt: File name

The hard drive boot sector still use the Bootmgr (Windows Boot Manager) in place of the NTLDR (Windows NT Loader).

Rollback data for installation is either damage or inaccessible.

In case of unsuccessful rollback operation, you need to format the hard drive and reinstall the operating system. This process has a downside that it removes all disk partitions and cause partition loss. In such situations, Windows Partition Recovery is required.

Recovery is potential through Partition Recovery Software. These tools are quite easy to use and work in most of the cases of Windows partition loss. The Partition Recovery programs maintains the integrity of your valuable data as they have read-only and non-destructive conduct.

Stellar Phoenix Windows Data Recovery is the most effective solution for all your partition loss situations. The software recovers all FAT32, VFAT, NTFS and NTFS5 file system partitions. It is usable with Microsoft Windows 7, Vista, 2003, XP and 2000.

Partition Boot Sector is one of the most significant data structures of a Windows hard drive partitions. It is a small area of hard drive partition, which stores critical information about the file system of your Windows operating system (either FAT or NTFS) and a small machine language program. The machine language program is required to assist the operating system when it loads. Operating system can not recognize the partition if partition boot sector is faulty.

In some cases, the partition boot sector may get damaged and it renders the hard drive partition inaccessible. The corruption may occur due to virus infection, improper system shutdown, operating system malfunction, and power surges. Nevertheless of the cause of this problem, it eventually leads to partition loss and require Windows Partition Recovery to be handled.

Resolution

When you suspect that Microsoft Windows does not boot up because the hard drive partition boot sector is damaged, use special Recovery Console option in Windows. This special recovery console utility is known as Fixboot to sort out all types of boot issues.

You can access this tool by booting your system through Windows boot disk. Enter the Recovery Console and type:

“Fixboot [drive]:”

The [drive] is letter of hard drive for which you need to repair the partition boot sector.

If the above method does not work, you need to use Partition Recovery Software that work in most of the partition loss situations. The applications methodically scan whole hard drive using efficient scanning techniques and ensure absolute Partition Recovery. The tools come equipped with interactive and self-descriptive graphical user interface and thus do not demand sound technical skills. They do not alter original data on the drive as they have read-only and non-destructive conduct.

Stellar Phoenix Windows Data Recovery is the most effective solution for all types of partition loss problems. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000. It recovers FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions and stored data.

As an practical example of this problem in Microsoft Windows operating system, you may come across the below error message when you try to create a swap file:

“The partitioning scheme used on your hard disk prevents the creation of a permanent swap file.”

The above error message prevents you from creating the swap files.
The problem occurs even if your using Virtual Memory dialog box when you install Microsoft Windows or 386 Enhanced alternatives in the Control Panel to create the swap files.

Root of the issue:

The above problem may take place due to any of the below reasons:

A Windows partition manager
Un-initialized files of the partition table
A virus or any other malicious program
Microsoft Windows operating system is quite cautious about the type of hard drive, when it creates permanent swap files. If you modify the Windows hard drive improperly, which is formatted through a special software, you may face serious data loss and disk error problems. To prevent data loss issues, Windows insures that correct format of the hard drive is recognized.

If you modify the Windows hard drive incorrectly, serious partition loss situations occur. Partition loss mostly occurs if:

Your system is dual-boot and both OS’s are using varying partition schemes.
Your system has deadly viruses.
In both cases, you lose your hard drive partitions and need to recover partition using powerful third-party applications.

The partition recovery software helps you to methodically scan entire hard drive and extract all lost partitions from it. The Windows partition recovery tools has interactive and rich graphical user interface to ensure quick and easy recovery in all partition loss situations.

Stellar Phoenix Windows Data Recovery software safely recovers lost, deleted, corrupted, or missing Windows hard drive partitions. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000. It salvages NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions.

“The partition table on device is corrupted. To create new partitions it must be initialized, causing the loss of all data on this drive” In such cases, the partitions still boot properly. But under the System Tools-> Hardware browser, you just see a large green bar for hard drive. It does not show the hard drive volumes. When you run fdisk to perform Data Recovery Linux, you get following result: “Disk /dev/hdc: 100.0 GB, 100030242816 bytes 16 heads, 63 sectors/track, 193821 cylinders Units = cylinders of 1008 * 512 = 516096 bytes Device Boot Start End Blocks Id System Partition 1 does not end on cylinder boundary. Partition 2 does not end on cylinder boundary. Partition table entries are not in disk order”

Root of the problem

As sated in the first error message, this issue generally occurs due to corruption to the partition table. Partition table is the most important data structure of Linux operating system that stores critical information about hard drive partitions. This information is required by the operating system to access hard drive partitions. In case of damage to the partition table, all of your critical data gets deleted and you need Linux Recovery to get your data back. This is possible through Linux Data Recovery software. The applications use advanced scanning algorithms to systematically scan the damaged hard drive and retrieve lost data from it. They have simple and interactive graphical user interface to allow Do It Yourself recovery. With read-only and non-destructive conduct

Stellar Phoenix Linux Data Recovery is the most effective and advanced tool that ensures absolute recovery in all cases. It supports recovery from Ext4, Ext3, Ext2 and ReiserFS file system volumes. The software is works well with all major distributions of Linux operating system.

Consider the following scenario. You resize your Windows Vista partition using in-built Disk Manger tool to free up some hard drive space. Then you install Linux on the newly created Ext4 hard drive partitions. At last, you create another NTFS file system partition for storing data that you formatted in Windows Vista and end up with a partition scheme that is similar to the following one:

sda1 (primary) Hidden (Recovery)
sda2 (primary) Vista C:\ (NTFS)
sda3 (primary) Linux \ (Ext4)
sda5 (extended) Swap Swap (Swap)
sda6 (extended) Data D:\ (NTFS)

Your systems works properly until you download and install security updates in Windows Vista. After applying the updates, when you boot your Linux system next time, fsck gives you a number of error messages about the multiply-claimed blocks by the Inodes of udev rule files. Udev corruption creates a number of issues with your Linux computer and renders your valuable data inaccessible.

In Linux operating system, udev is a device manage for 2.6 series of kernel. It primarily manges the device nodes in /dev. This is successor of the hotplug and devfs that meas it handles /dev directory and all the user space actions.

In such critical situations, you need to replace the damaged kernel files or even the kernel. It is possible by formatting the hard drive and reinstalling operating system. Although, formatting removes all of the hard drive errors, but also delete all the files from hard drive. In Such scenarios, you require Data Recovery Linux to extract data from formatted hard drive.

The Linux Data Recovery is possible through third-party applications, known as Linux Recovery Software. The tools perform extensive scan of entire hard drive and extract all the data from it. With rich graphical user interface and read-only conduct, the applications are easy and safe to use.

Stellar Phoenix Linux Data Recovery is a comprehensive software to ensure absolute and quick recovery of all your lost data from Ext4, Ext3, Ext2, FAT12, FAT16 and FAT32 file system volumes. The application works will most of the major distributions of Linux operating system including SUSE, Ubuntu, Red Hat and Fedora.

After the first reboot of Windows XP Setup, the user might receive any of the following error messages:
Stop: 0×0000007b (0xf898963c, 0xc0000034, 0×00000000, 0×00000000)
Setup has determined that Drive C: is corrupted and cannot be repaired. To quit setup press F3.
Windows could not start because of the following ARC firmware boot configuration problem. Did not properly generate ARC name for HAL and System path. Please check the windows documentation about ARC configuration options and your hardware reference manuals for additional information.
No operating system.

The setup might even halt with a blank black screen after the first reboot.
After the completion of the installation process, the secondary hard disk that worked well with other Windows operating system versions might not work here.
Now after this behavior, the up-gradation process may stop and the user cannot boot the system. The data stored becomes inaccessible and here is the case of data loss.

Reason
One can encounter this situation if he is using the hard drive overlay software for controlling the hard drive. There are few versions of the drive overlay software which might not be compatible with Microsoft Windows XP. So, the up gradation process does not accomplish and the user can face the critical situations of Windows partition loss and thus the data loss.
Solution
1. To avoid such problems, contact the vendor of drive overlay software to
inquire about the solution of such problems.
2. The user should never use fdisk/mbr command from Windows startup disk or
fixmbr command in the Windows XP Recovery Console. Both these commands
would destroy the drive overlay MBR information and it might cause severe
data loss.

To solve this problem, one needs to repartition the hard drive by using XP bootable CD and then reinstall a fresh copy of Windows XP. Formatting will remove all hard drive partitions and their data. Here comes the requirement of Partition Recovery.

Partition Recovery can be done in the best possible way by using an effective third party Partition Recovery software such as Stellar Phoenix Windows Data Recovery. This robust software works well for both FAT and NTFS file systems and carries out efficient and smooth Partition Recovery. Phoenix Partition Recovery software is compatible with most of the Windows versions including Windows 2000, XP, 2003 and Vista.

Are you unable to boot your computer from Linux operating system in a dual-boot configuration with Windows? Your system cannot recognize the Linux partition and you cannot access your data from the system? This behavior renders your Linux partition inaccessible and your valuable data irretrievable. Such problems may occur due to missing or corrupt hard drive data structures. It leads to significant data loss, if your backup is not updated. In order to recover lost data in these cases, linux data recovery comes for your rescue.

In a practical scenario, you may come across the below error message after you install Windows XP on a computer that has Linux Ubuntu already installed:

“root (hd1,1) Ubuntu/disks
Error 22: No such partition”

This problem occurs when you make your system dual-boot. After the above error message, boot process fails and you cannot gain access of your Linux partition. To get your valuable data back, you need to identify the root of this problem and perform data recovery linux by resolving it.

Grounds of the issue

You may encounter this problem due to corruption to the Linux partition or file system. Linux cannot read a damaged partition and access boot files from it.

A computer hard drive is divided into several partitions, which work as individual drives. You can use different file systems and can install different operating systems on these partitions as per your requirement. The hard drive partitioning is particularly useful for effective management of your precious data.

The hard drive partition and file system may get damaged due several reasons, such as virus infection, improper system shutdown, power outages, user mistakes, file system conflicts, and more.

Resolution

Try out the below methods to sort out this problem:

Boot your system from boot disk of Ubuntu operating system.

Run fsck tool to check integrity and consistency of your hard drive partition.

Format your Linux partition and reinstall the operating system.

Formatting can fix this problem, but it also removes all the data from your Linux partition and cause severe data loss. In such cases, Linux Recovery is the only way to go.

The Linux Data Recovery software enables easy and absolute recovery of all your lost data with advanced scanning techniques and simple graphical user interface.

Stellar Phoenix Linux Data Recovery is the most powerful utility that provides assured recovery of all your mission-critical data. The software supports all major distributions of Linux operating system, such as Ubuntu, Red Hat, SUSE, Fedora, and Debian.
