Linux MBR Overwritten after Installing Windows

Linux MBR Overwritten after Installing Windows

When you boot a Linux based system, the first thing that occurs is initialization of your hardware. After this, the Grub boot loader loads from MBR (Master Boot Record) of hard drive based on its configuration. You might see a boot menu displaying all the operating systems in a list from which you can start the system or the kernel initializing. If you don’t observer any such behavior, the problem is likely to be related to Grub or MBR. In critical situations, you might need to reformat the hard drive and restore lost data from backup. But in case no backup is available or you find it in invalid state, Linux Recovery tools can help rescuing all the data from crashed hard drive.


As an example, after you install Windows in dual-boot with Linux, you might fail to boot into Linux.

Cause

Such kind of behavior might be seen if MBR gets overwritten. This doesn’t allow you to boot into Linux.

Solution

You should try these methods to solve this problem:

• Try booting your system using Linux installation CD. Enter the ‘Linux rescue’ and use this command at boot prompt:

root=/dev/hdXX

where, ‘hdXX’ is the boot partition of your hard disk.

• Boot your system using Live Distro disc and mount the root partition of your hard disk to a temporary boot point. Next, you need to change your root to this point and reinstall Grub. To do so, you need to apply these commands in order:

mkdir /mnt/temp

mount /dev/hdb1 /mnt/temp

chroot /mnt/temp

grub-install /dev/had

• If the above measures fail, you should reformat the hard drive to fix all MBR related problems. Next, you should make sure that you have complete backup to restore the lost information in this process. If you fail to do so, you can use third-party Linux Recovery tools. Built with powerful recovery technology, such Linux Recovery applications serve as efficient tools to recover lost data. In addition, they provide you interactive user interface and advanced recovery options for complete results.

Recovering a Red Hat Linux System After a Power Outage

Recovering a Red Hat Linux System After a Power Outage

Today, the Linux operating system has carved a niche of its own. It has got a dedicated category of users who will happily pay for it if it ever comes with a price tag. The Linux system is secure, reliable, fast, and does not require hardware/software drivers to install them on the system. Having said that, even such a robust operating system can face corruption. Corruption can occur due to various reasons such as power outages, corrupt file system, human errors, damaged operating system, etc. In such cases, you should try performing appropriate corrective measures to sort out the issue. However, if you are unable to do so then you should use a third-party Linux data recovery software to perform Linux recovery.

Consider a scenario wherein you are working on a Red Hat Linux system. Suddenly, there is a power outage and the system shuts down unexpectedly. When you try to switch on the system, you fail to do so.

Cause:
The cause of this situation is that the Linux system has corrupted because of power outage.

Resolution:
If the problem is because of having a faulty hardware like bad hard drive or memory chip, the file system check may not be sufficient to resolve this problem. This happens particularly when the file system is corrupted. In such cases, the Red Hat boot process will produce an error message and guide you into a shell so that you can perform the file system repair yourself.

When the recovery shell dismounts all the file systems to mount the root file system in a read-only mode, you can perform full checks on it. To do this, you should run the e2fsck utility on the corrupted file system that will be able to resolve all the inconsistencies. Exit the shell and restart the system. The system will function normally now.

However, if you still are unable to recover the system then you should use a third-party Linux data recovery software to do the needful. Such read-only tools are able to recover the data safely without overwriting the existing data.

Stellar Phoenix Linux Data Recovery is a Linux recovery software that enables you to recover data from the corrupted Linux systems. It is supported by various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo, etc. This Linux data recovery software is able to perform ext2 recovery, ext3 recovery, and ext4 recovery. In addition, it can recover data from FAT12, FAT16, FAT32 file systems as well. This Linux recovery software is compatible with Windows 7, Vista, Server 2003, XP, and 2000.
