Get "prohibited" sign on startup, can't do anything.
OK, first of all, this is regarding the OLD Mac Pro (2008), not sure if that goes under Power Mac, these days. I'm not able to move the post to that forum at this time, so sorry about that.
I cannot start my system. There are some sort of "new" noise from the disk itself on startup. I get the chime and then half a second of the Apple logo, then I get the "prohibited"-sign and there it stays.
I've tried to boot in safety/alternative modes by pressing "Shift", by pressing "Command", by pressing "Command+R", but the startup scenario remains the same.
I've also tried to boot via DVD (Snow Leopard) by pressing "C" during startup, and I do get the DVD running for a minute or so, and the Apple logo appears, but then this also stays like so for 20+ mins. (Should be said that the current system is Mountain Lion, I don't know if this prevent me from booting with another system version DVD)
Any ideas on this are most welcome
