Well it's weird actually...
I'm only using the gamesave exploit, that's the only exploit I've ever used. And that MS Dashboard thing has been the case when it was working a while back, but I wasn't able to boot boXplorer.
But that's not my concern at the moment, I'm just wondering how to get to a dashboard. And I'm getting the error 21 screen whenever I just boot the Xbox without a disk in it (where the dashboard's supposed to be). So if anybody has some help or anything, thanks.
Btw, would it be possible if one of my friends copied his Xbox's C drive and I got it transferred to my computer, and then I were to transfer it to my xbox, would that work? Oh, and his box is modded using the gamesave exploit, and it's not biffed or anything.
