I've had a running problem with removing Linux from my Windows 7 laptop. Initially, it was installed as a dual-boot, and worked well. To remove, I deleted the partitions on my laptop. This removed grub, and I was left with needing to enter:

set root=... 
set prefix=... 
insmod normal 
normal

each restart. I didn't restore the Windows boot-loader and have since re-partitioned my drive.

Now, upon reaching the command prompt screen, an ls query showshd0, with three partitions, but none of them have a recognizable boot-loader as each returns with error: unknown file system.

Booting from a Windows 7 rescue disk doesn't seem to work, as it sends me to the same command prompt terminal.

All I'm looking to do is restore the boot-loader, either grub or Windows 7. Any help would be appreciated.

Thanks in advance.
