After install Quantal does not boot without live USB plugged in

[Colin Law]

After installing Quantal alph 1 from usb stick, with no problems reported, using entire hard disk for install, the system will only boot if the USB stick is plugged in. If it is not plugged in it does not start booting at all as far as I can see and there is no obvious hard disk action. With the stick plugged in it boots into the system installed on the hard disk and not into the live USB.

After boot I can eject the usb stick and the system continues normally.

Further information: gparted shows that the disk (sda1) has not got the boot flag set.

Setting the boot flag on sda1 and running

sudo grub-install /dev/sda
sudo update-grub

fixed the problem. Apart that is from the fact that my live USB stick is not a live USB stick any more, as booting off it just goes to sda to load the system. Presumably the installer installed grub to the usb stick instead of the hard disk.
