How great is you're pendrive ?
Which was the first boot drive during install ?
The internal drive or the pendrive ?
Do you BIOS allowed you to boot from the pendrive ?
Booting only UBUNTU from the pendrive can means that you have to change the sequence in the BIOS during boot .
this is what i did
i installed ubuntu from cd onto my pen drive
it had an option to install ubuntu alongside windows which is what i did
my pen drive is 16gb it was repartioned as 12 gb linux and 2 gb swap partition, the initial 2gb was left unchanged ( this info is from gparted)
about boot sequence:
i can boot from usb, but after this install i had to disable boot from pen drive to be able to boot into ubuntu
i tried to boot from usb by using another pendrive which has slax in it and it worked fine
so as i stated earlier i think grub was installed in hdd but the main grub files are in pendrive along with other linux files
