This question is an exact duplicate of:
- error: no such partition. Grub rescue 4 answers
Earlier I installed Ubuntu 10.04 from a USB flash drive.
Since the system was unable to detect Ubuntu in the initial menu that appears on reoboting, I deleted the partition onto which I had installed Ubuntu while in Windows 7.
I then installed PowerISO which prompted me to reboot the system.
Now however I get the following error:
error: no such partition grub rescue>
How can I fix this?
