So, I have gotten into this madness. I deleted my notebook ubuntu partition, wanted to delete the ubuntu. But alas, I forgot to restore the MBR. Well, no biggie if I can access live usb ubuntu installation (I install trough wubi before), but I just realized my bios is locked with supervisor password which I never set before. To sumarize it, this is my condition:

  • boot
  • get into grub-rescue
  • trying to access live usb
  • supervisor password lock
  • madness

And then I try to use boot rescue... The partition was deleted, remember? so I use my hard disk and copy /boot/ folder from my other notebook. I try this command:

set prefix=(hd1,msdos3)/boot/grub **to go to /boot folder in Hard Disk
insmod ntfs **i read that i need to load it to open ntfs disk
insmod chain **chainloader function
set root=(hd0,msdos2)
chainloader (hd0,msdos2)+1 **I get an "no such partition"

And I'm pretty sure the partition exist. So, if anyone could help me I would be very grateful.

Is it possible for you to remove the battery on the motherboard? That would reset the bios password. – Mixxiphoid Jul 16 '13 at 6:41
I'm not to sure about that, I read (CMIIW) that laptop store bios password in eeprom and not in cmos. Removing cmos battery will cause more problem... And it's a EFI InsydeH2O bios – Randvill Jul 16 '13 at 12:40
