I inherited an old WinXP/Linux dual-boot machine from the stoneage. Because it has Linux, the regular boot process is replaced with the Fedora boot loader; I cannot, therefore, press F8 strategically to tell my PC to boot from CD.

Even if I could, it's a moot point; the CDR doesn't seem to recognize any CDs. To make things worse, there's no option to network boot.

The original user is probably long gone; I don't know the password for any of the Administrator group users. I can login using my corp account, but that's unprivileged on this machine.

Since I'm not an admin, I can't do crazy things, like looking at boot.ini. Or deleting files. I only have 500MB free on my C drive. I'm pretty sure I can't boot from a USB, since I didn't see any settings for this in my BIOS.

How can I get admin access for my user?

Edit: Things I've tried:

• Boot from CD (CD not recognized)
• Launch CD from XP (CD not recognized)
• Install Daemon Tools Lite so I can install from an ISO -- don't have admin privileges
• XP password recovery tool -- requires admin privileges
• Adding an admin user -- no access to Control Panel > Users since I'm not an admin
• Logging in as both the admin users on the system (trying some standard passwords)
• Using Fedora to chntpw (the Fedora version installed is ancient -- 2.7)
