PC_Wiz - thanks for the reply. Yes, did try the "last known" and got the same error message. Latest is now booting to blue screen common XP error, regarding something "less than greater than equal to something" (didn't write in down, but have seen it referenced frequently). Will give the link you provided on Recovery console a good read and try some of the command lines you provided and see what happens. I did manage to copy corrupted file from another computer and pasted into windows sys32 with no joy. Did this by installing second bootable XP HDD C drive and opening failed drive as D.
Again, thanks for the reply - will let you know progress or lack of.
