Well ill let you in on a secret. You could have probably googled to find this but heres the fix. You buy a 2nd hard drive. Buy the upgrade version of vista. Unplug the hard drive with xp on it from your motherboard. You have to do this because vista will not install onto a second hard drive from within xp, it will bluescreen during install and nuke your xp drives bootldr. So you have a new hard drive plugged in only, throw in the vista install dvd. When it asks you to enter your vista key DONT DO IT leave the space blank and click next. Select the version of the upgrade you purchased and install it. You just new installed a 30 day trial of the os you purchased as an upgrade. THEN when vista starts, register it with your upgrade key, and voila you installed a 30 day trial of a full version and activated it with a upgrade key. Its that simple. Plug your xp drive back in and you will have to use f8 to decide what disk you will want to boot to after your motherboards bios screen. Default will be vista. You can change it in the bios. Im guessing you will use vista about 4 times before you find out its a joke
I'd like to install Vista Business or Ultimate upgrade on my current Opteron based system. However, currently my OS, Win XP SP2 is on an 80GB drive. Even now, this is cramped though I can free up a bit over 20 GB of space so that Vista will install. However, I'd like to install Vista on something larger, say 120 or 200 GB.
Do I need to reinstall Win XP on the new larger drive and then install Vista on top of that? Or how would I do this?
I've heard that unless the upgrade finds the former operating system on a hard drive, it will not allow installation.
Thus, how can I install Vista on a new hard drive without having the shell out the extra bucks for a full version of the software?
