Man, LAMF 's asking for help trying to save time, settings and data, and probably hasn't have something to implement the backup. Of couese, clean install is the best!
Unfortunatelly I don't know your system. On our pure Intel machines and on PIII c/w newer VIA chipset I did swap the harddrives with WinNT and Win98 on them.
You loose nothing if you try, and it doesn't take much time. You're thinking right. Boot-up in Safe mode, see the conflicts in the System Device Manager, delete conflicting devices, reboot and repeat the procedure.
By the way, our accountant works already one year on a completely new machine with mirrored from old computer harddrive on larger partition of the new harddrive .... We were very busy that time and we decided to reinstall everything from scratch some time later. Our system administrator approved the idea.
And we were very happy saving the accountant's personal settings, and of course, her time and nerves. So far Win98 - no crashes.
Don't worry, should work this way. Keep your computer healthy, study it.
