ok im new so sorry if this has been posted before or i posted this in the wrong spot. i downloaded backtrack 4 (final) and booted the iso onto a flash drive using unetbootin. i then changed the boot order so the flash drive was first. after i did that i got into backtrack 4 did the install.sh and now i cant boot windows 7. even after changing the boot order to default, i turn my computer on and get a message that says:

Ubuntu 8.10, kernel
Ubuntu 8.10, kernel (recovery mode)
