I got Windows 7 on a work laptop and I need to do some testing in Ubuntu. So I plugged in a flash drive, rebooted, ran the install and resized my partitions to 350 and 150. Everything installed fine, it rebooted and it automatically boots Windows 7, doesn't give me any Grub. I redid the install 3 times and every time it reboots right into Windows 7 without giving me any Grub option at any point. I have Quick Boot disabled, I can see the machine POST, but it still doesn't let me choose.

Never seen this before, any advice?
