Background - Friend has a p4 based system which had XP working fine, until he tried to reinstall windows.
Problem - He got a BSOD - unmountable boot volume when trying to reinstall
He gave to me to try and fix and thisd is a list of what I have done
Since blue screen - I am not even able to get windows xp cd to get to the menu screen.
I tried taking the HDD out putting it in another machine - worked - formatted it and reinstalled windows Xp on that machine - then moved hdd back to original machine - still nothing.
tried hdd from my computer ( with XP) and same error occurs when booting.
Most forums (including MS help) suggest recovery console, but cant actually get that far.
I put the hdd in another computer and ran RC from there
I used fixboot and fixmbr ( seperate occasions)
I even tried bootcfg
I deleted bootlog
I swapped DDR as well to check mem was not the problem
tried chksdsk and scan disk no errors
The bios settings are all correct ( as they were working before) - I have checked them , changed them and removed all non essentials.
I am completely lost as to what can be done besides getting a new motherboard. Any help is greatly appreciated as i have spent 40 hours in the last week swapping drives up and down, formatting, etc
