Not strictly dual-boot but is it possible to have a completely different o/s on each of my two hard drives. Both fully functional and independant of each other selected at boot up. Neither system relying on the other for any software support or start up procedure. I have had W98 on C and XP on D previously but D relied on C for the o/s selection. I don't want this, and it maybe that I have to select the drive I want from BIOS, but is there software that can operate this sort of dual boot system?
