XP Home boot problems and mup.sys file
Posted on 2005-04-16
Have an XP home PC that stopped booting properly. At start up there are two OS's listed as follows in boot.ini:
multi(0)disk(0)rdisk(0)partition(1)\WINXP="Microsoft Windows XP Home Edition" /fastdetect /NoExecute=OptIn
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect
I dont know what the first one represents but if it's deleted the computer does nothing and it's apparently the "main" one. If I move it to second the PC boots fine but into a different XP. There are usually 4 user accounts listed when the PC works, but there are only 2 users listed if I move the second selection to first place.
This PC originally had 98 installed and was upgraded to XP Home.
There are hardware or software changes. When started in SAFE mode the last driver is displayed is "Mup.sys".
I've attempted a repair w/the windows CD but a blue screen appears (I think it's the IRQ?? not less??).
The hard drive can't be so bad b/c I'm on it right now. If I could just get these two files in boot.ini to merge into one????
why is one OS letting me boot but the other one isn't????
