I have Lenovo Y560 Laptop on which installed Windows 7 and Ubuntu 11.10 as dual boot. Due to some reason I had to recover the boot loader using
bootrec.exe /fixmbr and
bootrec.exe /fix boot. It created one partition of size 198MB named "tet" and both Ubuntu and Windows were working fine.
Yesterday while making some changes in partition table I deleted that "tets" partition and after reboot im getting following error
Error:unknown filesystem grub rescue>
I tried to boot from the Windows installer CD and but it stucks at "Starting Windows" so I am not able to run the commands I have mentioned earlier and when I tried to boot from Ubuntu 11.10, it stuck at this error:
Memory full Can't kill any more process.
Please help me out.
