dzudo; Hi ! Welcome to the forum.

Right off hand I would say that grub (ubuntu's boot loader) is on the pen drive, rather than on the hard disk. Thus the pen drive has to be present to boot.
To see where grub has been installed run these terminal commands:

sudo debconf-show grub-pc
sudo grub-probe -t device /boot/grubTo identify all partitions/devices, with pen drive active:

sudo fdisk -lTo install grub:

sudo grub-install /dev/sda Assuming you desire grub to be installed on the first hard drive; And the partitioning is msdos scheme
