hello,
i have a similar problem so i`ve decided to post here.i hope it won`t be a problem.so let`s gwt to the point.
how did all start:
a friend of mine was watching a movie onhispc,meanwhile he was downloading some files through DC++.then suddenly the movie stopped.we tried to start it again and then we realised that the pc was hung up.We tried ctr+alt+del and some other stuff and after there was no result i pressed the reset button.the PC booted normally,there were no bios messages,no error reports,but whindows did not start.Then i tried Safe Mode.It started loading the files ,but then there was another hangup at Mup.drv(or sys maybe i don`t remember now).We`ve waited a while and the restarted again.This time we tried Last Known Good Konfiguration and still nothing.I`ve decided to repair windows.Booted from CD,windows started copying files and everything was fine till the moment when the Setup is starting Windows message appeared.Then another hangup.We`ve waited another 10 minutes,then i stopped the pc and took it to my place.I installed the hardrive as a master on my pc and it booted windows(in safe mode because i didn`t want to mess the hardware configuration).Then i installed my harddrive on my friend`s pc.I tried booting xp(both normal and safe mode) but it didn`t load.I`ve deciede that the ram was the problem so i removed it and installed my ram on my friend`s pc.No progress at all.Same thing.Then i got another idea.I tried to boot from one of my other partitions(fat32 with windows 98 installed) and the OS started.Win 98 worked!But XP didn`t!? I thought it may be caused by some kind of file system problem or MBR missmatch i was going crazy at that point not knowing what to think and totally confused.I`ve runed some test on my friend`s harddrive,checked the MBR,checked if it`s active/bootable,but everything was OK.The last thing i`m going to try is to install win xp from previously copied to the harddrive i386 folder(kind of slow,but it`s my last hope).If it`s not working again i`ll just install win98
and wait to see if somebody has a suggestion what may cause this strange problem.....
