Um...
So, you formated, and tried to install, but Windows only managed to copy some of the files? and then? any errors, or just restarted, or what happened?
U want to try a repair? if so,
Boot from cd(set cdrom to boot first in bios) and wait for it to load the setup windows screen. Then press R for repair. These will copy files on top of your previous install, and hopefuly work.
Does the screen get black when U try this?
Or are U talking about recovery console (the black screen with white writing) which U can get to before the setup loads by pressing R,also.
Recovery console uses command lines and U need to know what U are
doing, it's not like Repair (from the windows setup screen)
(at recovery console, U can do stuff, depending on what the problem is, like rename files, recover from a corrupt registry, bla,bla,bla....if your Windows won't boot, and have data that U don't wanna lose)
But I don't think U need recovery console since U formated the drive and if only some instalation files where copied. Then U need to do a repair from the setup screen, or format again, and try instaling again.
If U got an error from the cd, if U can, try borrowing another xp cd and try with that. If not, write back with the error you're getting, or what actually happens, after copying some files.
