Quick question,
Can anyone tell me if there is a quick way to delete all partitions on a hard disk? I know it's dangerous, but I would like to use a CD based distribution, open up a terminal and type in a simple command to delete all the partitions on a hard disk, or script the boot script to delete them for me.
This has come about due to troubles with FC4 and RHEL4 whilst doing reinstallation using kickstart, it seems that if partitions exist on the disk the kickstart will fail.
I'd think that writing zeroes to the start of the disk would wipe the partition table fairly well, e.g.:
# dd if=/dev/zero of=/dev/hda bs=1024 count=1024
That would zero out the first megabyte of the first hard disk, which should be ample I'd think.
Paul.
