I want to remove boot information from the MBR of an external hard drive:
1) Currently, the external hard drive has GRUB written to MBR
2) The partitions on the external hard drive are new, and did not exist when GRUB was installed to the MBR
3) I would like to erase only GRUB's boot information from the MBR while keeping the partitions intact
4) The partitions, in order are 40GB FAT32, 500GB NTFS, 120GB EXT3. They are all storage volumes, no OS.
5) Right now, if I try to boot from USB, this drive is seen and GRUB tries to load. GRUB then fails since there is no longer an OS on this drive.
6) If I tell the computer to boot from USB, I would like the computer to skip over this drive, rather then trying to boot it.
________________OLD ORIGINAL POST BELOW________________
I have an external hard drive (connecting via USB) with three partitions, 1FAT32, 1NTFS, 1EXT3. I need to erase GRUB from the MBR, but can't figure out how to do it. I don't want to replace it with another boot manager, in fact that's the problem, I need the drive to NOT be bootable. I've long since erased the linux partition that installed GRUB in the first place, and this is strictly a storage volume now.
I have Windows Vista and Ubuntu set up on my computer, so if you know of any tools I can use under either OS, it'd be appreciated. I also have XP on a virtual machine.
