Before this happened, I have both window7 and Ubuntu 12.04 on my notebook. I have some problem about Ubuntu update. So I choose to move to Ubuntu 12.10. Then I install Ubuntu 12.10. But I forget to install alongside window. So my window recovery partition was gone. I'm usuing Toshiba protege R835-p56x that have window license on it and I need that recovery partition back. So I tried "testdisk" to restore that partition. I did a deep search then I load "HDDRECOVERY" partition that I think it is what i need back. After I finish it and restart. Then my computer cannot boot. It shows "error no such partition. Grub rescue>". Please help me to solve it. I want the recovery partition back. I want to install window 7 and then Ubuntu alongside it.
Please help me
