This will write zeros to the first 64 blocks on /dev/hda - MAKE SURE THIS IS THE CORRECT DISK! The master boot record (MBR), the partition table, and and additional data from Linux software RAID and/or LVM will be wiped out.
This will make Windows XP's installer happy.
thanks for the info could'nt seem to find a linux rescue disk anywhere so ended up making a windows boot disk (using my other pc) and then booting to pc dos.. then used fdisk to delete partitions.. then booted up with the xp installation disk, that seemed to work ok.
