multi boot

[craarc]

and before anyone says why? its cause i want to see if i can get them all running no need at all just for the hell of it....

ok atm i have a multi boot screen showing

win7 64 on drive1

winvista64 both on drive 2
winxp32

ubuntu on drive 3

then thru bios boot manager i can select to boot into

win8 on drive 4

i want to be able to add win8 into the boot menu but cant seem to point the bootloader to win8 without loosing the abiity to boot to the others untill i remove the win8 install from the bootloader then all comes back to normal and i can boot into the originals again and win8 from bios boot manager

i also want to be able to run osx lion from another drive and enter that at sometime

any ideas ?
