I rather think the operator is confused. First you need to look at what

Well Karl you have to agree that this is confusing.:)
 

your bios did to the original HD. Your results make me think your old HD
became another HD in the chain so it looks like /dev/sdb now when it was
/dev/sda when alone in the computer.

Well yeah in a technical way.
 

    Look at what you bios has done. If these are both IDE drives make
sure they are not on the same cable.

They are SATA drives. And I only had some molex connectors around. So I used a molex to SATA adapters to connect the drives.

As for the BIOS, it shows two identical drives connected. And they both have the same booting code.


They might have been connected on the same molex cable extension. So if I understand correctly, just placing them on totally different cable would solve the problem?
