I had Ubuntu 12.04 + Windows 7 installed, I didn't like Ubuntu hence I deleted the partition. But I forgot to fix the MBR. Also I cannot access the mutiboot option using F12 at startup. So when I start, I get the Lenovo screen with F2, F12 options but none work, and then the screen shows:

unknown filesystem
grub rescue-

with commands ls I get:

(hd0) (hd0,gpt6) (hd0,gpt5) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) (cd 0)

and with set I get:

prefix=(hd0,gpt3)/boot/grub
root=hd0,gpt3

may be because I had installed my Ubuntu in gpt3 partition

can anybody fix this problem?

I would load the Windows installer DVD into the DVD tray, and change the BIOS to boot from it. That's what did it for me when I had the same issue.
