You do know that getting rid of it is going to make the reset of the drive pretty much unusable until a bootloader of some kind is installed. I hope.

You can get rid of it many a different ways. The easiest way will be to just install another operating system on the drive and that will (should) overwrite GRUB. Another way would just be to run FDISK on the drive and delete all the partitions, then recreate. That will overwrite everything.

The third and final way (Most difficult yet most efficient) is to actually instruct a program to destroy (Overwrite) the first 512 bytes of the drive which is in fact, the master boot record, where grub's initial bootloader is housed. If you can boot off of a cd into almost any version of Linux (Lindows too) the command "dd" should be available.

You can execute a simple command to overwrite the first 512 bytes of the drive.

Code:


$ dd if=/dev/zero of=/dev/hda bs=512 count=1



where /dev/hda is the name of the drive. It may be /dev/hd1 or /dev/hda depending on your distro. Just make sure not to indicate a partition afterwards like /dev/hda1 or /dev/hd1a

That command will write zero's (0) to the first 512 bytes of the drive. Pretty cool.
