Thanks for all your help! I had tried to install Windows and just let Windows help me get rid of Linux. Unfortunately I get a blue screen every time I try. Basically it’s shutting down b/c of a hard disk error (technical error codes: 0x0000007B (0xF7B84524,0xC0000034,0x0000000,0x0000000)). Not sure how I can get rid of it to get Windows to install properly. Any ideas?
I also tried this 2nd option (deleting sda2* and sda3 in Terminal). At first it seems to refuse to delete these partitions because the resource was busy (so the error message said).
But when I restarted the computer it would no longer find the operating system (installing Windows from this point on failed - see above). First message when starting up says “Error no active partition”.
When I tried to repair openSUSE it would give me all kinds of errors:
-“No Valid Linux Partitions Found”
-“No Mountable Partitions Found”
-“No Valid Root Partition Found” (x2)
-“Cannot read file /etc/fstab”
Since I could no longer repair anything, all I could think of was to reinstall openSUSE. Back to Square ONE…
Is there any easy way I could just go in and format my entire hard disk?
