You probably installed the MBR (Master Boot Record) on USB stick instead of hard disk. This could be related to mass memory storage enumeration issue at installation.
You need to reinstall properly Grub2 (the bootloader which includes the MBR) on the hard disk. For this follow this link:

or you might have the wrong setting in the /boot/grub/menu.lst (if that exists in your system).

Your system is looking for /dev/sdb1, which is probably /dev/sda1 when your stick is not connected and /dev/sdb1 if it is.

search the net for using root=UUID=... in grub and in /etc/fstab
and properly update the grub config

$ sudo update-grub

Can you help with this problem?
