How do I setup Dual Boot XP/Vista w/two HD's, not partitions?

Hello all,

I can't figure out how to set up dual boot with two complete, but seperate drives already running respective OS's fine.. I had two seperate HD's, one with XP, one with Vista Ult. already on them. I want to be able to dual-boot these but all I can find is setting up dual boot when installing one or the other (Vista w/XP already on or XP w/Vista already on). I have EasyBCD on hand..

Thanks, TJ

The very easiest approach is to install each system seperately (just disconnect the other HDD during installation). To switch between the 2 HDDs (2 systems), you just switch the boot sequence in the BIOS.
Advantage: No headaches with the MBR, you can delete each system independent from the other, switching the BIOS boot sequence is fast, etc.
Also, if you create a seperate data partition on one of the HDDs, you can share the data from both systems and do not have to worry about copying/synchronizing the data.

Each HD already has a full OS on it, which were installed seperately, with only one drive plugged in at a time (dont ask..).. one hd has XP Home, the other drive has Vista Ultimate.. so right now I am going into the bios to select which drive is primary, which it will boot from. It is a hassle doing this, and beyond my wife or kids to do it.

set up a bootloader. you can partition your first or second hdd and installa linux distro or install grub from a live cd. well if you are going to install linux (i reccommend ubuntu its the most stable) wehn you triple boot these, ubuntu will already set up grub 1.97 beta4 for you. but you can always go in and edit the bootmenu: Customizing Grub2 boot menu - Ubuntu Forums

or you can research on google on how to install grub off a live linux cd. you can always setup lilo (not reccomended as that it is an old bootloader)

GRUB = grand unified bootloader, meaning that it loads most operating systems, even mac ones, i think. oh, and when you set up grub, set it up as a mbr on a partition with an operating system on it instead of its own partition.

i could be wrong, if i am sorry!

'not a fan of ubuntu.. so it's not an option.. It's XP, Vista, and shortly, 7.. thanks anyway.

try tirple booting win 7, i think itl make a boot menu for u but im not sure.

you can also try other linux distros if ur not a fan of ubuntu. open suse is another great linux distro to use.

I'm just trying to get XP and Vista to db now, so when I add 7 I can get it to trip-boot together..
