Yeah, I tried to delete it using Windows Partition 7 but when I right click on the drive all the options are "unavailable". So is there a different way besides using Windows Partition 7 to delete it ?
Please allow me to help a bit
as far as I'm reading this thread, the error could be caused by the Bad Disk, and your PC tried to boot using that disk.
however, if Partition software is able to detect it, then Windows should be able to detect it as well, only it will still be a "bad disk"
my suggestion:
check your BIOS setting, on the Boot Options.
I'm quite sure that the faulty disk is in one of the boot options in the BIOS.
you can set the boot option #1 (first device to boot) with the good disk, and set the other boot device to [NONE] (or something like that)
Let's see if you can boot into Windows this way.
BTW, is there any data that you want to recover from the disk?
