Well, if this HDD does not have an OS installed on it and ready to boot from, and it's left first in the boot order, you will get the error you describe.  It can work just fine as an external drive because it is not being used to boot from.


You likely need to change your boot order to put either the optical drive or USB drive first and have it be bootable and able to install the OS of your choosing.

Does the 500GB drive have Windows installed on it?

And, just how old is that laptop?  There are numerous older BIOS' that wont work with a drive larger than 127.99GB.
