Some multiboot options replace the Master Boot Record Loader program with their own, to ensure they come up first and load the program from their partition.

To fully remove this type of program, it is best to start over deleting everything on the drive and reinstall. You will first need to rewrite the MBR (Master Boot Record) and recreate your partitions.

1. Create a bootable floppy.
2. fdisk /mbr

If this does not remove the program, then you will need to use the Hard Drive Manufacture's utility and perform a lower level format to rewrite the Hard Drive Profile and MBR.

Some viruses replace the Master Boot Record Loader program with their own, to ensure they come up first before the Operating System. In rewriting the bootstrap, sometimes they damage it and make it impossible to be removed easily.

To fully remove this type of virus, it is best to start over deleting everything on the drive and reinstall. You will first need to rewrite the MBR (Master Boot Record) and recreate your partitions.

1. Create a bootable floppy.
2. fdisk /mbr

If this does not remove the virus, then you will need to use the Hard Drive Manufacture's utility and perform a low level format to rewrite the Hard Drive Profile, MBR, and zero out the drive.
