After using the recovery disk for a factory restore my  Inspiron N5010 fails to boot  after restart. The recovery disk seems to work correctly. It's only after restarting my computer I come to the boot manager screen. I've used certain tools such as start up repair, but nothing works. I ran a dianogstics test and the message I get is Running Mats test pure call!  How can i fix the boot problem. My computer was running fine before the restore.
