Boot failure after loading mup.sys

[Guest]

Today my xp pro won't boot. When booting normal the boot process hangs with a black screen before the login windows appears. When boot into safe mode the system hangs after loading mup.sys. Any ideas how to fix without reloading xp?

Thanks

The exactly same thing happened to me,i ended up trashing the Xp and putting
back w98,i tried everything i knew and then some.Some people recommended a
clean install and i dutifully dowloaded the 6 floppys and tried and
nothing,wish you luck.

Just out of curiosity,if you find out what it was please post the solution.

I had this same problem… unfortunately what I'm about to say will not
make you feel warm and fuzzy 

I recently did a few hardware upgrade(s) (power supply, graphics card,
memory and CPU fan) keep in mind the system was running fine before
this upgrade… after putting it all back together I went to boot the
machine and got the screen that said window was not shutdown properly
and had the options of, start normally, last known good config., safe
mode, yada - yada - yada… I'm sure you have seen it. I didn't think
much of it and just selected start normally, the system just hung. I
did a reboot, tried safe mode and it hung… btw, it appears to hang on
Mup.sys just because that is the last file it loads, but doesn't have
anything to do with the hanging. So, I decided to try a repair from
the xp disk. When I booted from the disk everything appeared to be
working fine, but after it copied all the initial files to memory and
tried to start the utility it hung! Now I was getting really nervous.
I decided to put the system back the way it was, same problem. I
thought it was my hard drive… went out and bought a new one, same
problem. I tried another graphics card, same problem. At this point I
knew it was either my processor or motherboard. I got both just in
case, but felt it was probably the mobo, so I decided to replace it
first… and that worked!

My conclusion, this is defiantly a hardware issue. When changing the
hardware I must have fried some controller (my guess it was the IDE
for the hard drive since I had no activity on the light or sounds
coming directly from the drive)… I guess it could have been worse; I
could have lost a bunch of data. When it happened I read a lot of post
about the same problem and a lot of people were saying "just disable
mup.sys" and other software related fixes… I wouldn't suggest any of
it, look towards hardware. Btw, it was the exact same mobo, so I did
not have to reload anything in the OS. Later…

This is a real problem.

It happened to a friend on mine back in December (Xp - Dell Laptop), another friend in January (win2000 - desktop), to me in February (Xp - desktop) and another friend just today (Xp - desktop).

The December, January and February event required re-installing software. The Xp recovery disk reported that the file type on the boot partition was "unknown". It was NTFS.

Today's event was recovered by using Nortons goback tool (reinstalled the system from 4 days ago).

If someone knows how to recover from this, please post. I'm sure others will also experience it.
