Microsoft made major changes in how the new operating system gets
installed. Unlike XP and prior versions were the conventional wisdom
was to turn everything on (printer, scanner, external drives etc..)
before attempting a install, so Windows could "see it", it is now best
to turn everything off and if you can, uninstall what isn't absolutely
necessary to boot and have mimimal control. In other words, only
connect your keyboard, none USB hopefully, a mouse or some kind of
pointing device (I prefer a trackball) and for hard drives switch them
to IDE mode if you can from BIOS. Also just have your root drive
(likely C) as the only drive if possible for starters to avoid more
issues. If you only have a single SATA drive and you boot from that,
you may be up the creek without a paddle. The potential for receiving
a BSOD error early on in the install process, likely at the 21% marker
is petty high. Ditto for many other drivers Vista don't like.
If the Vista Upgrade Advisor even hints there may be something wrong
disable whatever that device is before to avoid common BSOD screens
during install. A 7B stop is more common then it should be.
Once up, then put back your goodies one at a a time and change back to
SATA mode ONLY if you have approved and certified SATA ready drivers,
otherwise you could end up back at square one again.
As far as the video problem, try to reboot into safe more during post
(hold down F8), then if successful go to device manager, find the
video card, REMOVE the drivers, reboot. Windows should install some
generic crap, that at least allows your in until you can obtain VISTA
drivers from some place OTHER THAN Microsoft... of course.
If you're more the river boat gambler type and can't wait for Vista
approved drivers, many webs sites already have lists of XP drivers
that supposedly work, but were held back by Microsoft from the offical
release of the Vista DVD which apparently was blinded to them, every
if they are already on your system due to licensing issues. This may
explain the excess number of devices being rejected by the Vista
Upgrade advice and the false claim it "don't know" about the device it
is nagging about. One such site follows:

If you see your device on the above list or others you likely will
have to attempt to manually install the driver or just wait till a
Vista approved version is released.
