Osx does not recognise any DVD or disk inserted
Hi Everyone,
Since this morning I tried to use some disks on my MacBook Pro, (6,2) mid 2010, but the system did not load any of them and as long as I tried to insert one, it was espelled 5 seconds after without being loaded by the OS, I actualy tried to put a disk containing an updated version of Debian, and it would not load into MacOSX, but misteriousely, debian's installation started from the same disk and the same drive i tried to use on macosx .
It is actually quite strange because I cannot understand how it could be possible that the same disk actualy loads on the Boot and it does not whithin mac osx.
Any suggestion on how to solve ?
Thank you very much,
Regards
MacBook Pro, OS X Mountain Lion (10.8.5)
