Black screen with a non-blinking underscore after bootscreen

by Jrodbrown / September 9, 2010 3:00 AM PDT

I just upgraded to Windows 7 on my Toshiba Satellite Special Edition laptop that came with Vista 64bit and the other night i downloaded iTunes 10 and told me to restart my machine so I clicked ok and then my laptop shut off and when it came back on the Toshiba screen came up as usual but seemed to stay on longer than normal then it goes to a black screen with a underscore that blinks for a few moments then becomes solid. Ive tried to use the "F" keys to get different boot options because i have the windows 7 ISO disc and a ubuntu disc that I could use but whatever i try my laptop wont process it just does the same thing over and over again and bever proceeds to the actually boot up windows. what could be going wrong and how can i fix this? i'm seriously thinking about staying with linux...since vista and W7 have been screwing up terribly the past 2 months.

Sorry I can't answer what went wrong here. All I know is that the two answers above are things that I try in cases where I get the blinking cursor. There are more but the steps change slightly as we try one thing then the next.

The good news is that it worked so we move along!

It's a great last ditch tech trick. I wish it was more widely known. Pass it along,

Start a new post but be aware the underscore on screen is a well discussed failure.
