Windows 7 taking over 3 min's to reboot

Hi,

I've got three (3) identical pc's: Acer Veriton M4630G-i7477X
each with 32GB ram. Business level pc's.

Two of them reboot in about 35-40 sec's.

The third one takes about 3.5 min's to reboot.

When it starts booting up, I get this screen:



This pc just came back from Acer for a bad HDD; it was still under warranty.

Acer sent it back with its original configuration and installed a new HDD;
the original had a bad sector.

Anyone have any idea why this one pc is taking so long to boot?

Many thanks! :)

Ok, Ill have a look!

Thanks!

Well that made a huge difference!

The first thing on the boot options list was:
REALTEK PXE B02 D00

I moved this to the bottom of the list.

Now I'm booting from:
1st: HL-DT-ST DVDRAM GHA2N
2nd: WINDOWS BOOT MANAGER
3rd: REMOVABLE DEVICE
4th: REALTEK PXE B02 D00

Now he reboots are down to less than a minute.

But I'm still getting something I don't understand.

When it boots up, for a second there flashes
"Press Shift + F10" to enter some kind of
RealTek thing.

When I press Shift + F10 I'm taken to this:

Attachment 395593

What is this?

Do I need it?

Can I get rid of it?

Thanks!
