this might sound crazy so i'll explain
i have an old pc running xp just fine, but xp doesn't handle discs over 2tb properly so i need to use vista or win7 to have a single 3tb partition
i'm concerned my current install is a bit fragile in that some of the old hardware and maybe some old apps won't run properly or at all, plus it's a load of hassle reinstalling a load of apps and fixing all the settings the way you want, so i was wondering if i can somehow clone/ghost/copy my xp install to a separate partition on the same drive, so i can dual boot into both xp partitions, and then upgrade from xp to vista on one of the partitions (that's an upgrade keeping all apps, settings, drivers etc - not a clean install), and see if that works properly, then make a ghost/clone image, then upgrade (again not a clean install) to win7, so i have win7 with my apps settings and hopefully hardware working and can use the full 3tb drive space. and i can play about with it for a bit to make sure i'm happy before deleting the xp partition
an alternate solution would be just to clone/ghost image xp before starting, then do the upgrade as explained and see if it works and then roll back to xp if not, but i'd rather keep my working xp partition and play around on a second partition, so if i need to use anything that's not working i can just reboot instead of having to reinstall, and i can still play about with win7/vista to see if i can get the not working bits working if that's the case
is this possible, and if so how? do i maybe ghost to an image, create the partition, then restore the image to the empty partition then use a bootloader program to allow me to dual boot, then install vista, then win7? (as you can't jump from xp to win7 and keep settings)
cheers
