Is there any way to remove the Deep Island from Uru without needing a disc? My disc doesn't work anymore, and I want offline back.

No, there is no easy way to do that. A lot of files are overwritten during patching, you'd need a rather complete backup of an offline POTS.
You could easily have both (DI and offline) side-by-side, but I guess it's too late for that now, too.

Oh, okay. I'll get a new disk, I guess.
