I have just installed 12.04. I previously had 11.10 installed, with
/dev/sda6 as the install partition mounted at
/ and with
/dev/sda1 mounted at
/home. When installing 12.04, I duly selected the same options, with no reformatting. I selected
/dev/sda6 as the bootloader partition. I was warned, as expected, that the system files on
/dev/sda6 would be deleted.
After reinstalling, I can't get past GRUB: selecting the main boot option, or the recovery mode option, both give me the error "No such partition", and the option to go back to the main GRUB screen.
What's going on here? What partition is it saying doesn't exist? And obviously, how do I fix this?
I get the error three times; it looks like:
error: no such partition. error: no such partition. error: no such partition. Press any key to continue ...
This also happens with the "Memory test" boot options.
Entering the command line and running
ls gives me the same error.
