Well it's been a long day of experimentation with my computer, attempting to have 3 OS's installed on my computer, WINXP, UBUNTU, and Vista, with no luck, I decided to restart my computer and see what changes might had been made. When I did I got an error along the lines of "Grub error 17" something of the sort on a black screen after my hardware loaded up and everything. Well after hours of researching I found that GRUB was related to Ubuntu to manage multi-os's on boot. So I saw some forums explaining that if I got installation discs for Ubuntu and loaded them on the boot of my computer that I could re-install GRUB and hopefully my problems would be over...well after I download the latest version of Ubuntu I tried to burn it to a disc...with about 6 programs to no avail. So finally I started messing around with the BIOS trying to see if anything was wrong with that, couldn't find anything so I decided I could try re-installing windows and using the tool that reverts back to you know like earlier that day or a week ago w/e that I could just try that....so now after re-installing windows xp pro sp2 I just get a black screen at startup with a blinking line, prompt if you will. Oh yah I forgot to say that I reverted my BIOS to default as well. So then I tried using the Recovery tool trying to, from there, revert my computer to an earlier date since I couldn't get past the black screen. Well basically here is my problem now. I have followed tutorials telling me to make my root in recovery tool "C:\windows\system32\config" and then using commands to rename system files so that I can have my boot settings changed to default. Well for just about all those commands I get a response saying "The system cannot find the file specified." including the command "fixboot" which I have only used in the root directory. So anyways I'm pretty much screwed cause I never really knew what I was doing in the first place and I have a BUNCH of files on here that I actually needed and now I don't know what to do. So I am posting, on about 20 different forums, looking for answers, hoping that someone...ANYONE, can please please help me revert my computer back to a time before I tried having 3 OS's. Thanks in advance, Andrew L.
