Go to SolutionUEFI problems setting boot options
Have a 7773 using UEFI, bios. I can't find anything that helps me get the boot sequence or F12 to see USB. Tried turning off secure boot and turning it back on. Nothing changes. Does not see or list the drive in boot up menu. Any help would be greatly appreciated. Need to clean install Windows 10 from 11. It's been 3 months since it was upgraded. System very slow. Want to go back to !0 for now since laptop not in list to support 11.

The drive does not need to be in the boot sequence. Connect it and press F12 a few times at startup - a UEFI-bootable drive will then show up in the boot list.

Are you sure the flash drive is UEFI-bootable?Use Rufus, which is free, to create UEFI-bootable USB flash drive from Windows 10 ISO file. I have one that is created for installing Windows 10 v21H2

If the system doesn't see the drive as bootable, it's not UEFI-bootable.
Best option is to use the Microsoft Media Creation tool -- it will make a UEFI-bootable flash drive.

Rufus can be used but be careful to read the documentation -- it can equally well create media that isn't UEFI-bootable depending on what options are chosen.

Using a Dell provided Windows 10 USB(media mentor) drive. Is there any other way to check for UEFI useable? Rufus never heard of. How do I get it?

I have done that. Still will not see drive. The drive is a Dell media mentor drive with Windows 10 on it. Wouldn't that show up on the listing?

Since I don't know the purpose of a media mentor Dell drive, could you describe its use. Some folks seem to be saying is for a specific purpose so it may not be usable in that system.
Also, make sure the drive is plugged in before you boot the system and you might attach a disk management picture with the drive showing.

Hello, the Dell media mentor usb drive is supposed to be in this case a Windows 10 install on the usb drive provided by Dell with new systems. I will boot up and see how disk management sees this drive. This is what the dell laptop sees that usb drive.

This is what is showing on the drive. If I'm not mistaken the .EFI is supposed to be that UEFI boot is it not?

It depends entirely on how the media was prepared. The surest way is the Microsoft Media Creation Tool.
The presence of the EFI folder (/efi/boot) is only part of the requirement.

I ended up using Dell recovery to rebuild my system. I used the "not save" files option and let it run. I believe I should create a boot able usb with the Windows 10 on it. I did get the Bios to read the drive, but the drive would not boot up to the point to install Windows 10. I thank you all for your help on this. I'm back up with Windows 10, it did not fix my problem with 100% disk usage which is what started this whole adventure. I will open new thread on this problem for help.
