Of course your Mac is fine with your original HDD because OS X is stored in there.


Can you give us the exact model of the Crucial SSD you put in also do you have a SATA to USB adapter like this one: Startech 2.5" SATA to USB adapter if not you'll need it to prep the SSD manually.

I solved it by installing a HD instead of a SSD

Then it sounds like either the data cable is bad or the SSD you were trying was not compatible in someway. Often I see people forgetting to reformat their drive to GUID or they needed updated firmware on the SSD unit with this series.
