I went through the steps listed on but it does not work. I start up my Toshiba Satellite laptop and press F12 to pull up the boot menu. I select my USB drive and the screen goes black for a few seconds as if it is loading up. There is a quick flash followed by a black screen for a few more seconds and finally ending with the system shutting down. I can still access the BIOS and the boot menu, but I can no longer start up in Windows (system resume nor system recovery).

Edit: I'm not 100% positive but I believe this is my laptop model -

Have you done the obvious? (Try redownloading and loading the image; use a different flashdrive) – user606723 Jan 6 '12 at 19:36
What video card do you have ? Did you check the MD5 sum on the iso ? – bodhi.zazen Jan 6 '12 at 19:40
bodhi - I'm not sure on the graphics card and I can't start up to look into that and I am not sure what I would be looking for in the md5sum file. I looked at it but there isn't anything that jumps out at me as an error but I am no expert on this. – David Starkey Jan 6 '12 at 19:50
user606723 - I tried it once and I could still get into Windows after the boot failed. After that first fail I re-did the steps outlined by the Ubuntu site and tried again. After that I came to the situation I mentioned in the question. – David Starkey Jan 6 '12 at 19:53
bodhi - If I got my Toshiba Satellite series correct I believe the graphics card is from the ATI® Radeon™ 3100 series. If you need other specs, I believe this is the correct laptop – David Starkey Jan 6 '12 at 20:01

I made a disc version of ubuntu and booted from the CD drive and it worked. Maybe the files I got for USB were corrupt or incomplete somehow, I'm not sure. Anyway, I got it working.
