UEFI Boot Question

On a windows 7 Desktop (HP Compaq Elite 8300 SFF) the uefi is set to legacy and yet even if I move the SATA0 setting to first in the list  the PC wants to boot to the USB drive if it is plugged in.  I uploaded a picture of the boot order screen.

When I see this, the BIOS does not use the boot order correctly and needs to be updated. Sometimes that does not always work. I tell clients not to leave USB sticks or USB drives plugged in as some computers just do not do it correctly.

Now that was an unsatisfying answer<g>. I figured a bios update was in order. I've also seen where some people say "Apply Defaults from the File menu in BIOS" will fix the issue.

Yes I understand. I work with lots of client computers and some insist on booting from USB if there . BIOS updates do not help in these cases.

Try updating BIOS and see if it helps. If that works then great but it does not always work

In the image you posted, SATA doesn't look as if it comes before USB. Usually boot orders are from top to bottom.

move usb hard drive below sata0

Your USB floppy and USB hard drive are sitting over SATA, sure it wants to boot from USB. Move the SATA to the top.

I have moved the SATA0 over the uSB drive and it still wants to boot to USB drive or PXE as long as the USB drive is plugged in

If you cannot fix it as per above, then as noted, your particular machine is going to start from USB unless you remove it. Very simple workaround.

Is the UEFI now disabled or enabled? Does the same screen shot USB over all other boot devices?
David Johnson, CD, MVPRetiredCommented:
you can hit f5 and disable items that you don't need.

Are there UEFI boot files on the USB drive? If so it may be UEFI-booting and you will need to edit the UEFI NVRAM boot list using the Setup options and delete the USB entry. OR change the boot order so it boots to legacy first.

Well, the answer was... Seems that the hard disk had a bad boot sector. This morning the machine failed to boot at all with the USB removed. I fixed the MBR and Bootrec and all is ok. I never saw a boot sector manifest itself in this manner and because the machine booted without the USB the day I was working on it, I got mis-directed. I appreciate all of your suggestions.

Well that explains it. System would always seek for next bootable device if the main drive is no more bootable.
