To keep a long story short I was in system properties - computer name clicked on change and changed the highlighted box from domain to workgroup and after I restarted my computer it won't let me log in with my password and username. I get an error message saying make sure your username and domain are correct... The only options I have are username and password and I don't see a way of changing the domain. I would like to just format the hard drive and do a clean install of windows but I can't figure out how to format the hard drive without getting into windows and for some reason it won't load from my XP CD even after setting the CD-ROM as the default in BIOS and there aren't any recovery disks available for my computer. Any suggestions?
