View Full Version : [ubuntu] Upgrading to 12.04 deleted windows 7

May 5th, 2012, 04:21 PM
When I upgraded from Ubuntu 11.10 to Ubuntu 12.04, it worked, but my windows partition comes up as unknown on disk utility and I can't boot it. How do I fix it without losing all of my data?

If it doesn't open in the file manager, it doesn't look good. Open the terminal and post the result of:
sudo fdisk -l (small L)

for a start.

Try running update-grub in a terminal or from Ctrl-Alt-F2, then reboot. That may fix the boot issue if your Win7 setup isn't corrupt.
