I hope there is no hardware failure. Anyways...

Boot with ubuntu. use Gparted to delete ALL partitions on HDD. Create new partition table (will be listed under 'device') choose 'msdos'. Don't create partitions. Reinstall Windows and use its utility to create and format partition.

Then download either BODHILinux or Fedora_xfce and install. I suggest you try BodhiLinux... it is based on ubuntu and most of the commands are same as Ubuntu.
