View Full Version : [ubuntu] [SOLVED] QGrubEditor & Error 13: Invalid or Unsupported Executable Format

July 24th, 2008, 02:10 PM
I have a dual boot, Windows/Ubuntu, situation on my laptop. Last night, I edited my Windows description to say "Windows XP." This morning, before I left for work, I tried to power up Windows and received "Error 13: Invalid or Unsupported Executable Format." As far as I can remember, I only changed the description. I did this late last night, and it's possible that I clicked something by accident.

Please note, my laptop is at home and I'm at work. At this time, I'm just looking to see if there's a quick fix.

Thanks in advance.

Could you please post the output of:-

cat /boot/grub/menu.lst

It is:

title Windows XP

chainloader +1

title Ubuntu
root (hd0,5)
kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=6670870a-669d-4f86-b8ca-36d5d8530d28 ro quiet splash

The weird thing is that both the roots of Ubuntu and Windows are the same, so the Windows entry must be wrong in that sense. Can you post the output of:-

sudo fdisk -l

Your last post tipped me off and I solved the problem. I changed my Windows root to 0 (root (hd0,0)) and it worked. I logged into both Windows and Ubuntu and all is good with the world, at least until the next break.:)

Regardless, thanks for the help!
