I have several partitions on my computer [one for win7,Chromium(not yet installed), and Ubuntu] I am using windows 7. Recently, I installed the daily build of Natty Narwhal Ubuntu (11.04). It was too slow for and I couldnt use Unity, so I wanted to uninstall it. I deleted the partition from Win7 that it was on and restarted my computer. Then I get an error saying:
"error: unknown filesystem.
Now I can't access Windows 7 or anything
I've been searching for hours for a solution. I tried to reinstall Ubuntu by booting from a USB but it didn't work (I also enabled USB as first in the boot sequence); all I get when I tried to do that was a blinking "_" charachter. I also tried to use Super Grub Disk but to no avail; I got the same result. Can you help me fix this? I am worried that I might have permanently bricked my comp. I would preferably like a fix method in which I could fix it from the "grub rescue>" line. Thanks in advance.
EDIT:I do not really have any important docs on my compy
