My internal harddisk in my laptop got corrupted so I have removed. I loaded desktop ubuntu for testing from pendrive. Now i want to install to my external hard disk. It already has 650gb of data in ntfs format.

Remaining space i splitted to ext4 and installed. When restarting, am not getting ubuntu loaded from HDD.

Please explain how to make my ubuntu load from external hard disk.
