UEFI and Windows 7 64bit

Hi all,
I have ASROCK h77 pro4/MVP motherboard with 2500k processor.
I also have 2 hdds.
1) 500 GB seagate sata2 internal on which windows 7 is installed with UEFI(GPT).
2) 2TB goflex
When I boot with my 2tb goflex attached, every time windows boot manager goes into recovery mode and gives "insert proper boot media error".But when I remove the usb connection to goflex I can boot.Ones the windows boot there is no problem attaching the usb drive.
Now I have to remove the usb connection every time I boot.

The problem sounds like your bios is listing your USB device in its order of preferred bootable devices before your hard drive, solution go into bios (with USB device attached) and change the order! Regards

If not set first to boot, try wiping the 2TB with Diskpart Clean Command after moving the data off.

Check also there are no BIOS updates needed to run larger HD's.

My boot priorities are shown in image.
It says windows boot manager as first.
And I tried disabling everything else but still it doesn't work.

Is the 2tb showing up as a bootable device in USB BBS priorities?

Try also triggering the one-time BIOS Boot Menu key at boot to see if the USB shows up. It may have nt60 bootsecting or other boot sector code on it which is interfering and which requires wiping.

Yes it shows up in BBS usb priorities.
So how to wipe the Boot sector code without formatting the drive?

You'd have to move the data off so you can run Diskpart Clean Command.

First try to remove the USB from BIOS Boot order as Stormy suggests below.

Before going through all that, have you tried just setting the "boot option 3" to nothing instead of listing the USB drive?

P.S. One real nice thing about UEFI bios, you can actually take screen shots from it (F12 according to the manual for your board). All you need is a USB key to save the image to, then copy it over once back in Windows.

I did that but still the same.
I re-installed the windows with keeping the usb attached still it does not work.

Why did you keep the USB attached when reinstalling Windows 7?

One should always unplug all other HD's during install to insure the boot files are correctly installed to Windows 7 partition or it's 100mb System Reserved partition.
