* manipulate the volume bytes that are associated with volumes in Windows NT / 2K / XP * perform attribute changes on partitions listed in the MBR Partition Table (hide, activate, delete etc.) * create a blank backup-file to create a MBR from scratch and restore it later
* perform above mentioned edit, bootcode, display and dump functions on the MBR backups * display the MBR sector or dump the MBR sector to file * refresh the MBR bootcode, without destroying the Volume Bytes * backup, restore, wipe, clean or dump the track 0 for a disk * backup, verify and restore the MBR, using backup-sectors or files MBRtool allows you to do the following things: 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've long since erased the linux partition that installed GRUB in the first place, and this is strictly a storage volume now. 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.
#GRUB ON USB TO BOOT HARD DRIVE HOW TO#
I need to erase GRUB from the MBR, but can't figure out how to do it. I have an external hard drive (connecting via USB) with three partitions, 1FAT32, 1NTFS, 1EXT3. GRUB then fails since there is no longer an OS on this drive.Ħ) 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. They are all storage volumes, no OS.ĥ) Right now, if I try to boot from USB, this drive is seen and GRUB tries to load. I want to remove boot information from the MBR of an external hard drive:ġ) Currently, the external hard drive has GRUB written to MBRĢ) The partitions on the external hard drive are new, and did not exist when GRUB was installed to the MBRģ) I would like to erase only GRUB's boot information from the MBR while keeping the partitions intactĤ) The partitions, in order are 40GB FAT32, 500GB NTFS, 120GB EXT3. Updated to be clear about what I'm trying to achieve (original post at bottom):
