Shift F-10 when you install WINDOWS and you call diskpart.
select disk 0
clean disk
(You did more than format the disk, if you did that. Now you have to
re install WINDOWS), format the disk and re install loosing everything you have. Get your recovery disk or Backupper program to re install your system image.
A raw hard disk is needs diskpart, or if you have a hard to install hard drive, you can try diskpart. It is like fdisk.com. A powerful command that only the experienced should have used. Get your
installation keys for all the programs you have, and re install, and get your files you backed up.
x:\source>diskpart
diskpart>list disk
diskpart>select disk 0
diskpart>list partition
diskpart>clean
diskpart>create partition primary
diskpart>select partition 1
diskpart>active
diskpart>format fs=NTFS quick
Sorry to see your having problems. Maybe the disk is good and you only need to re install and format the disk and then re install your Operating System.
