Sounds like a Chimp clone problem due to the fact, as others here have suggested, it sounds from the description as if it was, somehow, run from a memory card. If it was installed then possibly something to do with that:-
Chimp 261812 [b]must[/b] be installed ie. mandatory in either one of six E:\ drive only locations on the HDD/SSD being cloned.
Read the readme that Rocky5 provides with Chimp:-
E:\applications\chimp
E:\applications\chimp loader
E:\apps\chimp
E:\apps\chimp loader
E:\chimp
E:\chimp loader
The seventy Xbox and various skins mention must be on F:\ (and G:\ if used) so was that partition actually cloned? It should have taken many hours to do that. Did it?
With an unlocked HDD, as it probably is on a chipped machine, I'd be looking at using FATXplorer on PC to resolve most and probably all of these problems and do it faster than any Xbox centred solution.
