I’m using Vista on a sony laptop. I recently bought it this year around April. Things started happening after I downloaded the the Windows Vista Service Pack 1 (update). But when I restarted, my computer never fully boots. The booting stalls, than shuts down. Then I have to take out the battery to get my computer back on, after trying this a few times. I’ve tried starting up in Last Configuration (boot stalls forever, then fails after being exhausted) , I’ve tried bootin in safe mode the screen just stays the same in the with crapy numbers and stays that way. I was told just inserting the recovery disc, that it should instantly boot from the CD, but it doesn’t. I’ve notice that the computer maybe trying to boot from the hard drive. Which could explain why the booting options fail. What do you do to start booting from the optical Drive?
