Removing Linux
 

"You can wipe away the partition table of the hard disk in linux by issuing the following command (in command line mode, after you've logged in as root):

dd if=/dev/zero of=/dev/hda bs=521 count=1

However, I get this output?

output of sfdisk -l and mount might help

sorry? I don't understand. You want what?

At the command line (where you tried the "dd") type(first command uses a lower case ell, as in list)

Not a good idea to play with "dd" like that if you don't know what you're doing - I suspect that bs should be 512. Won't matter much in this case.

The request for more info is relevant to determining if hda is really the drive you want to modify.
Regardless of what command you use, we need more info on the configuration of your system.
