iMac 27" Late 2009. Only Boots Into Recovery Mode

This late 2009 iMac has: 1tb hardrive 4 Gb ram i7 core process

Will only boot into recovery mode, so there is something wrong with it. Could most likely be fixed but I don't want to bother.

Could also be used for parts.

Also includes wired keyboard and magic mouse. And a wall mount adapter

See profile for ISO.
