Quoting Shorty
It's turning into a long thread

Im not surprised
That should do the trick mate

Ok I know you guys must be sick of all this by now, but yes - I am having the same trouble. I did try the stuff from
http://kellys-korner-xp.com/xp_sys32.htm but it didn't work. (couldn't do the dir system part from /windows/system32/config/ cos apparently it couldn't find it)
However, before trying anything else I reinstalled windows xp professional on the computer on seperate partition so I could copy/back-up my files before i had to use my back up discs (which basically removes everything)
Also my laptop is a tablet pc(acer c320) so my partition running windows xp professional is kinda useless as I can't use any of the tablet options (the computer didn't come with windows xp tablet edition disc, but was already installed with it)
So I have no idea what to do now, considering i've tried so many things.
I tried fixboot from recovery console but that didn't work. I was also gonna try fixmbr but its got me worried that I may lose my files. (it says Fixmbr may damage your partition tables if you proceed. This could cause all the parititions on the current hard disk to become inaccessible.)
I also booted from the cd and did what Tex said about doin a fresh install - and then to see if it checks for previous installs - but unfortunatly it didn't do that. So whats that mean? something wrong with boot.ini?
I suppose i could try the back-discs but for some reason i can't copy my files, tried to copy to external drive but it just doesn't detect it, tried writing to dvd error comes up, tried putting the files on the network - also doesn't work.
Its like, I can see my files - but I can't do anything with them!!! Help please.
I would love to call someone to help, for free

But I'm in london, england - any technicians/helpers here in the UK?
