I booted backtrack 5 32 bit KDE on my Acer D270 via a live USB then installed it on to HDD. When booting via USB it was fine but now after installing onto HDD it loads up into Ubuntu 10.04 load screen (where it has 4 dots to show loading) then just goes black and remains there.

I've already re installed and used a different USB but same result.

Any help would be appreciated thank you.
