Hello I've been trying to fix a problem with my pc all day and cant, so any help would be greatly appreciated. I'm using an ACER Power F5, Windows XP Pro. The original problem: Basically i couldn't log on. I decided to format my C drive, i inserted the windows xp disc and booted my pc from the disk but i was getting the "Setup did not find any hard disk drives installed in your computer" error. So i downloaded my driver on to a floppy disk, and managed to the windows installation screen and tryed installing window again on my newly created C drive. The installation does complete (goes to 100%) but then comes up with "Setup cannot copy the file: m5287.sys" with the options retry, skip or quit. anyone know how to fix this? i've also attempted to boot with my backup disk, which gets to 27% and then comes up with "error 0xf000005" and after restarting the pc it tell me the file NTLDR is missing. Any suggestions? thanks in advance.
