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.

Likely what has happened is that GRUB is trying to find the formatted partition, but cannot. When this happens (I have personally experienced this) GRUB goes into rescue mode.

If it is possible to boot from a "Live CD" then you should boot so (into Ubuntu) and follow the following tutorial: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows

Yes, it does say it is for after installing Windows, but it serves this purpose perfectly as well.

@saltpetre What BIOS are you running? Also, have you tried the dvd on a different computer? –  Brenneman Oct 27 '12 at 4:03
