I deleted the Ubuntu partition via Windows 7. I rebooted the machine and I it drops to a
Grub rescue prompt.
I tried to boot from Ubuntu live DVD, USB and Windows 7 Repair CD, but didn't succeed. I also tried to changed the boot sequence on the BIOS to boot from CD/DVD, but got the same.
I also updated the BIOS to the latest thinking it might be a BIOS issue but got the same.
Machine comes up to
grub rescue prompt.
