Restore computer problems

[PaulJoe4]

Recently my computer froze, i turned it off, turned it back on, and just kept loading and loading and loading. I tried the command+S thing and the terminal kept saying it couldn't find root mount, errno 19... Or something like that. I took it to geek squad and they told me to try to restore it (command+R). So i took it home and did that. I tried installing mac os lion but it didnt give me any options to put it on. NOTES: I'm able to get to disk utility.

Which version of OS X did your MBP ship with? From your question, it seems that you don't have restore disks. If it shipped with Lion, then the CMD+R thing should work. If it shipped with Snow Leopard, it is possible for this to work with a firmware update (depends on the model). Which MBP do you have?

Snow leopard

If it came with Snow Leopard, then it should have restore disks. If you have those, I'd reinstall using the restore disks and then upgrade to Lion.

If you happen to have a different Mac around, you may want to try to create a bootable USB to reinstall Lion.

By the way, when you looked at Disk Utility, does it still recognize the hard drive is there? Have you tried running the Apple Hardware Test?
