I'm trying to install ubuntu-12.04-desktop-amd64 from my usb stick. When booting from usb I instantly get a blank screen (with a grey box at the left bottom)

I checked the live system with my well except it also starts of with a black screen and a grey box at the bottom.

I figure the Problem is my geforce gtx 570 since older versions of Ubuntu where only able to boot with xforcevesa and nomodeset. Unfortunately I can't change the boot parameters.

I tried the alternate version for a text based install, but it has the same problem. If I press Esc in the alternate I get a message box with two buttons but no text.

I would be happy for any advice on this matter

Did you try waiting a while when the black screen with the grey box at the bottom appeared? Because I booted into live after waiting a while there. – harisibrahimkv May 2 '12 at 11:25
I waited for some time yes (~5min). At some point it changed to a blinking cursor and afterward nothing happened. I figure the grey box was the starting menu and afterwards the boot stopped because of a graphics card problem. Since I can't change boot options e.g. remove quite I can't be more specific – traubi May 2 '12 at 12:08
I tried my live-usb on some other computer today. This time I was able to see the initial boot screen. I wrote down the exact keyboard commands to change the boot options and will try it "blind" at home. – traubi May 3 '12 at 11:02
This time it worked. I can see the boot screen and change the boot parameters. Maybe the iso I downloaded with torrent had an error, or I just needed some other system to create my live-usb ... – traubi May 4 '12 at 6:39
I'm having the same probleme on a SonyVaio – obounaim Jun 20 '12 at 16:30

Honestly, I would try a CD, if you don't have a CD Drive, (Rare, but it happens.) I would try redoing the the flashdrive with pendrive again. If still no luck, I would re-download the .iso... I myself have similar issues, so I'm trying Wubi again, and if you have Windows, if the CD or USB don't work, and nothing above works, try Wubi and I know it's not ideal, AFAIK support won't be available in the future but it could be an available option.

I have noticed a few problems with a usb install try burning a cd I always use a cd and have had no problems but could not get it to boot from usb

Actually there are USB keys (such as those U3 ones) that offer emulation of a CD drive for a "partition" on the drive. So using a USB key doesn't mean it appears as anything other than a real (USB) CD drive to the computer. Check out u3-tool if you're curious. – 0xC0000022L Jul 4 '12 at 20:33
That is intresting so a usb can emulate beed a cd this sounds grate the reliability of a usb with the compatabillity on an iso will have to look for one of those. – Mark Kirby Jul 5 '12 at 15:35
