I installed backtrack 5 r3 32 gnome iso to my usb flash drive on my laptop (which is 32 bit system with win7 os) with the unetbootin exe. I went into bios and changed the boot settings to boot from usb. When it restarts it takes me to the unetbootin screen where it has the options (default/backtrack text/ backtrack no drm etc). I choose default and it just restarts and takes me back to the unetbootin screen.

I never had this problem with back track 3. Backtrack 3 just loads up fine. What am I doing wrong?
