I already have dual-boot with XP Pro/98SE up and going. I'm not going to use
NTFS because that then locks out using the drive under 98SE.
As I still have 98SE running on this "unchanged" other than XP Pro's boot
loader, it's easy enough to boot with a 98SE startup floppy and "SYS C:" the
system, reboot back into 98SE and just delete all the XP PRo stuff to
completely purge any remnants.
I'm on my 4th install of XP Pro already and only started a week ago

Each
previous attempt to install resulted in my making some basic wrong decision
early in driver installs etc. that never seemed to be "repairable". In fact,
the first install went south after installing a sound card driver. XP Pro
wouldn't boot to desktop from any user, including when starting in Safe
Mode. I "fixed" the booting problem by first booting with a 98SE startup
disk and then manually deleting the newly installed sound card driver files
from system32 folder (been around long enough to know the filenames of
Creative products).
In any case, other than the overall smooth look and feel I can't really say
I'm very impressed with this OS. As usual, everything's now laid out
slightly differently, found under different dialogs, using slightly
different terms etc. etc. And of course the worse problem is that Help still
never actually explains anything but instead always simply points you at
some wizard. A prime example is just trying to figure out the implications
and consequences of changing "services" status. I've got no idea why I at
home want, need and even have installed (let alone have running) all the
myriad of miscellaneous "auxiliary" programs that seem to have nothing to do
with my using this pc for my own purposes.
Oh, and I've crashed IE and Explorer here more than once already. I've also
managed to lock her up to the point a cold boot was required . That tells me
all the same old bs is till there. In other words we still don't have that
stable, robust OS BG told us we'd all enjoy back when 95 came out ...
remember the promises ... still unfullfilled.
