I am trying to reformat my hard drive. I boot with my windows XP cd and press any key to boot from CD. OK set up menu appears. I press enter to continue set up. I never get much further than this as I either get dmboot.sys corrupted, ntfs.sys could not be found, or setupdd.sys could not be loaded error 7. It then suggests I start up from cd and choose "r", but I can never get to this point. I decided that the best bet would be to reformat disk, but how do I do this if I cant get this far in setup. I have tried another XP Pro disc but have exactly the same problem with this. Please can anyone help?
