Because you installed the grub on the USB flash drive:/dev/sdb, should be mounted to the hard disk:/DEV/SDA
---------------------------------------------------------------------------------
Now, plug in the USB stick and start Ubuntu on the hard drive
Then, uninstall the USB drive, unplug the USB flash drive
---------------------------------------------------------------------------------
Next, install grub to the hard drive (this ....) Depends on how you partition, there is no separate/boot)
I guess you don't have separate/boot, but you can't guess if you xp+ubuntu dual system
---------------------------------------------------------------------------------
Suppose you are a single system, only two partitions one is/, one is swap
Execute this code: sudo grub-install--root-directory=//dev/sda && sudo update-grub
---------------------------------------------------------------------------------
Suppose you are a single system with three partitions//boot/Swap
Execute this code: sudo grub-install--root-directory=/boot/dev/sda && sudo update-grub
---------------------------------------------------------------------------------
And so on ........ .......
Then reboot to see if there is success: sudo shutdown-r now
