i soon as i select it, the xbox reboots! or the dash reboots itself, depending wat mood its in! is this a bug or a error on my part???

i have this problem ONLY with the commerative build.

i duno wat build i got, i only just literally downloaded, everything else works fine from here

I had this problem too i had UIX on C: Drive UIX would boot then after like 3min or so it would reboot then do the same boot cycle over n over so i had to switch back UX

anyway to fix this? or is it just a fairly big bug
