A very confusing post>
My understanding is that you deleted a Linux partition and now the whole hdd is inaccessible. Corrupt partition info.
First check your BIOS for root sector protection (blocking writes to sector 0).
A root kit virus may have gotten to your root partition and redirected it.
Sometimes, normal attempts to fix this will fail due to deliberate sabotage by the virus.
It can be very difficult to fix a disk that BIOS is rejecting.
I must recommend taking the disk to someone who has the hardware to rewrite the partition information.
There are some very dangerous direct I/O write tools that can access hardware devices without requiring BIOS recognition of it as a disk.
I recommend some of the disk recovery literature for that answer, to get it right.
Once the partition is written back to something readable (even if wrong), then partition recovery can see the disk and recover the real partition settings.
Do not mount it with a wrong partition info, just let it be read as a device by the tools.
Boot a CDROM linux and use Parted if you have too.
