View Full Version : [ubuntu] XP install possibly corrupt after installing ubuntu

December 2nd, 2008, 10:58 AM
Hey, I set up a dual-boot system with ubuntu and XP on one single drive, two partitions. Since installing ubuntu, I can't boot into Windows any more because NTLDR is missing. Using fixmbr, fixboot or bootcfg /rebuild doesn't help and if I try to use a windows boot disk, it says it can't find ntoskrnl.exe. chkdsk also can't scan the drive because of some major error and gparted can't scan it either. I can't mount or access any data on that drive from ubuntu.

This is the error from gparted after trying a disk scan:

GParted 0.3.8

Libparted 1.8.9

ERROR(22): Opening '/dev/sdc1' as NTFS failed: Invalid argument
The device '/dev/sdc1' doesn't have a valid NTFS.
Maybe you selected the wrong partition? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? This error might also occur
if the disk was incorrectly repartitioned (see the ntfsresize FAQ).


I can probably assume from all of this that my windows partition got corrupt at some point and can't be accessible either way.

Is there a way to recover this? Or is it just a case of reinstalling windows? and presumably if I want to use the same drive again, reinstalling ubuntu as well?

Search for 'meierfra' in this forum. He has a good XP repair thread.

That looks like what it is I need to do, but since I can't mount or access any data on the partition, I can't replace the missing files.

Do a "sudo fdisk -lu" (that's a small "l", not a one) and post the results here. That will at least confirm whether or not your Windows partition still exists. If it does, you may be able to use testdisk to repair it.

You can also use Super Grub to boot/repair your XP:
