[Bug 65080] Graphical install: GParted modifying partition table leads to Windows Bluescreen on boot

[ekmek]

Public bug reported:

Binary package hint: gparted

I recently installed ubuntu with the graphical installer on a Thinkpad
R50p. Everything went fine so far, but when trying to boot Windows again
through Grub, i immediately got a bluescreen with a STOP 0x0000007B
(inaccessible boot device). Even the Windows Setup and recovery console
won't recognize the hdd as a valid disk.

After several re-installations and tests i was able to track the error. The steps to reproduce, starting on a disk with one NTFS partition (taking full size).
1. I first resized the Windows (NTFS) partiton to make space, rebooted to Windows, after a chkdsk, everything was ok.
2. I then rebooted the Ubuntu Live-CD and started gparted. There i created an extended partition and two logical volumes (ext3, swap).
3. Rebooting to windows (no Grub yet installed) brought up the same behaviour (bluescreen on boot).

A workaround to resolve the issue without killing the whole disk or reinstalling Windoze:
- Boot a live-cd with qtparted (Knoppix, Kanotix), start qtparted
- Delete all logical and extended partitions
- Create an extended partition and the logical volumes
- Apply and reboot

I'm not that in to disk editing, so I wasn't able to examine the
partition table to tell what's the difference between gparted and
qtparted on creating extended partitions, but there must be something
messing up the partition table (for Windows).

If you need any further information, please contact me.
