Hi all, I had a problem with my modded xbox botting, I got a very restrictive menu with not many options. Got the latest Slayers disc, but still no luck, as the disc wouldn't boot. I tried a manual upgrade and now have 'error 21'. I know this is only a software problem, but my sticking point is making the xbox boot from the Slayer disc so I can do a full rebuild. Can anyone please help with tips on how to force the xbox to boot from the dvd and not the hard drive? Thanks!
