So I popped in a windows 98 boot disk in an attempt to formatt my drive C and start anew with XP. Now that I changed my BIOS around, performed fdisk to assign all my memory to drive C, and rebooted once again to further fornatt the partitions I had apparently just created, nothing's happening. I reboot the computer and it just goes to a black screen that reads, "Error loading operating system". Any help is appriciated.
