Will need some help with changing the boot order in the BIOS.

At Boot Device Priority it shows:
1st Boot Device - [Removable Dev.]
2nd Boot Device - [Hard Drive]
3rd Boot Device - [ATAPI CD-Rom]
4th Boot Device - [IBA GE Slot 0228 v1109]

I've tried changing the order but can't figure out how to do that. The only thing I can do is to highlight the 2nd Boot Device - Hard Drive and 'Disable'. I didn't save the changes yet. I don't see how to enable it again if I do.

Am I on the right track with this?

Thank you, pk
