Boot override allows you to set what device you want to boot at only the next boot up, for example if USB is in P3 and you want it to boot, bypassing the HDD.
Is there a one-time BIOS Boot Menu key? Doesn't it show every bootable advice? Why the override then? Just askin.
Yes there is a button, in this case it is F8 (F5 to get to Advanced options) and is another choice is all. I think all retail motherboards offer both.

Yes from what I've seen most all retail mobo's offer a one-time BIOS Boot menu key, and also setting in BIOS setup to prioritize the boot devices.

What I don't understand is the need for the Boot Override settings at all if you already have separate settings in Setup for Boot order priority, and a one-time BIOS Boot menu key which gives all choices.

The key is a lot easier to use than drilling down through a lot of BIOS menus, I guess? I have no good answer for why both though, it is what it is, as they say.

Does anyone else know? I don't have a mobo like that so can't test the difference.

Override must have some ancillary function rather than just duplicating the Boot Priority on the same page.

This page seems to cover everything, and just came up for the first time searching Asus BIOS UEFI and Boot Override jointly. I think it is new ("Under Development") since I've been looking for a page this explanatory for years and just checked last week: Architecture Intel Sandy Bridge -- Info-Coach

That's a great reference Greg.

My question now is, does Beanster reset BIOS and make changes as required or does he try to unravel what was done before and then make changes as required?

My take is a reset and using the page you found along with your and Gary's knowledge to make changes to the optimized settings. It's entirely possible that the reset will be sufficient. The screens I looked at show F5 as the reset key.

Any thoughts?

He got it installed. If performance is OK he should leave it.

If he wants to troubleshoot a UEFI install he could use another HD plugged in alone. If he really wants UEFI then he can save an image and try troubleshooting one on SSD.

But he said early on he didn't even want UEFI so we can wait for someone else with identical issue to find this thread as often happens.

Agreed.

I was wondering about the Fat32 considerations for USB installs and UEFI. I think it might be easier to direct members to use a DVD instead of a USB drive when UEFI is involved. It simplifies things for everyone.

  • In order to be detected as “UEFI bootable” a device needs to have a specific EFI file in a specific location. For example if you place a Windows 7 X64 DVD installation disk in your DVD drive it will be recognized as an UEFI boot device and you will be able to perform the Windows installation in UEFI mode. In contrast a Windows 7 X86 DVD installation disk does not have the appropriate efi file and therefore in that case the DVD will not be displayed as an UEFI boot device.
  • Beware that you cannot boot in UEFI mode from an USB stick formatted in NTFS (UEFI do not handle NTFS partitions). For example a Windows 7 X64 Installation USB Stick created using the “Windows USB DVD Download” tool provided by Microsoft will not boot in UEFI (but work well in BIOS legacy mode). Therefore you have to format the USB stick in FAT32, make it bootable, and copy the proper files in the proper location (see references at the end) so you can successfully install Windows 7 X64 in UEFI mode from it.

Gentlemen,
I am now communicating from the desktop and not the iPad. After resolving the password issue, and the network driver issue, I followed the instructions from post # 42, then began the Updates. I'm experiencing the same problem that started this whole mess: Important updates failing repeatedly to install. I cannot get a screen shot from here. F12, Print Screen, Alt-PrintScreen --- no captures. I will try manually installing each update to see if that will work. Back later...
