BOOT freeze with Segate 2TB USB3 connected

Hi all

I really need help with this

I have a new computer with ASUS P8Z77-V-Deluxe
a new Seagate 2TB USB3 that worked perfectly with my older computer

When it's connected to the new computer, it gets stuck on boot logo
MB Q-Code shows "b2" code. Which is Legacy Option ROM initialization

when i cold start the computer it boots fine.
When I restart the computer it gets stuck.
When I reset, it works fine again.
So every restart it gets stuck.
When I disconnect the drive, I can restart with no problem.

the external seagate is not setup to boot in BIOS.
Please help
