Big Problem with XP

So I have been having some problems with my computer, they started out as networking issues detailed here http://forums.majorgeeks.com/showthread.php?t=149242

Someone suggested trying to repair from the Windows boot disk so I attempted that. I did the system install then chose repair. It went through, told me to eject disk and restart. So I did, when I restarted it went to the setup screen for Windows I didn't have any options so I figured thats how it was supposed to be. So it goes into the install and at the end asks for the coa key. Which I managed to lose cause I suck at life. So I am smashing my head on the keyboard now at this point but no big deal I can just turn off the computer go into my Windows and get the key. Wrong. I try to restart the computer with disk in drive or out of drive and it goes to setup screen again and again. So now what? I have the original disk that I bought from Frys, is the coa on the disk? Either outside or in a file in there? I also have the original package, I bought it oem so it is a manilla envelope with a bunch of microsoft stickers on it. I have the numbers:end item pn, carton no, printer id, label part no, internal part, work order no. There is also something that says coa barcodes but it is a 14 digit number so I know that isnt it. So now I need to know can I get the code off a disk, are any of the numbers that I listed useful in anyway? Can I get back to my desktop? If I get there is it possible to get my original coa? Can i reset the bios so it boots from my c drive and forgets this setup ever happened?

 

1. Put your XP disc in a PC that is running Windows (doesn't have to be XP).
2. Click "Exit" when the big blue window opens.
3. Open My Computer, right click on the drive where the your XP disc is and select "Open".
4. Browse to the "i386" folder and open it.
5. Browse to the text file called "UNATTEND.txt" and open it with Notepad.
6. Scroll to the end of the UNATTEND text file, and there it is... YOUR PRODUCT KEY!!!
7. Write it down for future use so you wont "suck at life" when it comes to XP product keys.
