SUMMARY

This article describes how to remove the LILO boot manager from the Master Boot Record (MBR).

MORE INFORMATION

When Linux is installed on your computer, it allows a dual boot by loading a boot manager called LILO directly into the MBR. To remove LILO, perform the following steps:

If Linux is Still Installed

Run LILO with either the -u or -U switch. The device name has to be the second parameter.

  • For example, if LILO is installed to the MBR of the master drive on the primary IDE controller, the command would be:

    lilo -u /dev/hda

    Where dev is the device directory, hd indicates an IDE hard drive, and a indicates the master on the primary IDE channel.

  • To use with a SCSI drive, run lilo -u /dev/sda where sd indicates a SCSI drive and a indicates the first drive in the chain.
  • If there are multiple partitions on the drive, indicate the partition number for LILO to uninstall by adding a number corresponding to the partition number on the drive, starting the count at 1 (not 0). For example, the following command removes LILO from the first SCSI drive, first partition:

    lilo -u /dev/sda1

    NOTE: The sda indicator has nothing to do with the SCSI ID number.

If Linux is Not Installed

NOTE: The following procedure is not supported by Microsoft and is done strictly at the discretion of the user. Microsoft assumes no liability for lost or corrupted data. This procedure should be done only as a last resort.

IMPORTANT: fdisk /mbr removes the disk signature from the MBR. If this drive is a member of a Windows fault tolerance set, it will no longer be recognized as a member of that set.

  1. Use the Windows Resource Kit Disksave.exe utility to back up the MBR and boot sector.
  2. Boot to MS-DOS and type the following:

    fdisk /mbr

  3. Restart your computer.

The computer should start normally. If the computer does not start normally, boot to an MS-DOS boot disk and run Disksave again to restore the MBR and boot sector. You may also need to run Fdisk to specify the new active partition to boot.

The only difference between the two switches is that -u checks the time stamp on the current MBR and the backed-up one, whereas -U does not check the time stamp at all.
