Home::HowTo::Dual Booting

This is going to be really brief, because I can't be bothered to write much.

I recently wanted to combine two machines - one was a linux box, the other ran Win2k. I decided to just stick both HDDs into one machine. Windows obviously wouldn't cope if the hardware was altered beneath it, so I simply put the old linux disk in as slave to the Windows primary master.

LILO can't boot Win2k, or at least Win2k won't boot from LILO, so I let the Windows boot loader do the work. Using Knoppix, I used LILO to write to /dev/hdb1 (linux /boot partition). I then used dd to take the boot sector from this partiton and save it to a floppy.

dd if=/dev/hdb1 of=/tmp/bootsect.lnx bs=512 count=1

I then rebooted the machine into Windows, copied to boot sector file into c:\ and added a line to c:\boot.ini


Job done. When the machine boots, the Windows boot loader gives the option of booting into Linux, and when selected, this runs LILO.
