I went to their site, gave my .NET passport and was given a link to download the x86 or x64 versions of Vista (In quite a few languages actually)
This is where it gets interesting. The download completed and I proceeded to burn two copies. One for myself, and another for a friend that got his Vista beta serial, but is in Wyoming and doesn’t have access to broadband.
I promptly backed up all important data to my removable hard drive (a nifty little laptop hard disk in a small case that only requires USB2 to run, very handy) disconnected that drive (nobody want’s to partition the wrong disk) and rebooted.
Following the reboot I let it boot from the DVD. Vista immediately asked for a key, which is a nice touch because I hate getting through 85% of the install and THEN being asked for it. The key was put in, I deleted my old NTFS partition and let Vista begin the install. About 6% of the way into copying files I get the error:
Error code is 
I read all kinds of things about setting your RAID controller to other modes or whatnot, but if you didn’t require extra drivers or different modes to install XP, then you shouldn’t need anything extra to install Vista. Quite the contraty, you should require less because Vista will come with updated RAID drivers and all that. (Hopefully the ability to load RAID drivers from a COMPACT DISK because floppys utterly suck)
The most likely reason for this is that you got a corrupted ISO or that your disk burnt improperly. Luckily I have a laptop with a DVD burner in it, so I redownloaded the ISO and burned the disk at 2x. It took about 20 minutes to burn all three gig worth of 5384 goodness, but it was well worth it because Vista installed smoothly afterward.
If you’re thinking about trying Vista. Then here’s a link to the tool that will tell you if you meet the minimum system requirements.
