Hello, I've got an asus Motherboard with UEFI. It's set to UEFI boot mode and I've disabled secure boot. I'm trying to get it to boot a Linux thumb drive and having no success. If I put in a windows talking PE and boot, pressing f8 (the key on my motherboard to bring up the UEFI boot menu), then when the menu comes up, down arrow three times, the windows PE loads and it will start talking. This was created with Rufus. If I try a Linux-created thumb drive, in this case Debian10 live, for example purposes, I put it in, f8, down arrow three times, enter, and nothing, no boot beep, no drum sound, nothing. What i'd like to do is set USB to be first in the f8 UEFI boot menu, I believe this requires altering the bcd. Can anyone confirm this and if so do you have a procedure? The ideal outcome is I put in any bootable thumb drive and start the system and it boots it. If there's no bootable thumb drive in the system the system goes to the second choice, win10. Thanks. Dave.
Hi, I can't see how you can do this without manipulating data in the BIOS for the boot order to be honest. I just tried writing a Debian live ISO to a USB drive and was able to boot it fine using UEFI using my normal procedure on this machine using the boot menu I know from past experience. Interestingly enough when using a Windows USB drive it can show up on the boot menu as both the UEFI USB drive and Windows Boot Manager, I think that has something to do with the signed UEFI boot image but not sure. This can sometimes mess up the order of the boot menu in the BIOS. I have this sometimes when I want to boot from a Windows USB drive, I have to use a different amount of down arrowing to get to the right place. Whether there is an active OS on the hard drives makes a difference as well.

Hello Andrew, Thanks. In your UEFI is the mode set to UEFI or Legacy? Do you have Secure boot on or off? Do you have CSM on or off? Lastly, do you have to format/provision the USB drives in a specific way? Thanks. Dave. On 7/27/20, Andrew Hodgson <andrew@hodgson.io> wrote:

Hi, UEFI mode with Secure Boot switched on. This machine is very old (from 2012) so may be lacking on some of the newer stuff. I don't use anything special to write USB drives, just format them as FAT32 then use Winrar extract function to extract to the root of the new drive. That works for Linux (Debian) and Windows. If you are using a modern Debian distro it should beep twice when it gets to the menu.

You can modify the EFI boot order under Linux using the efibootmgr command: https://www.linuxbabe.com/command-line/how-to-use-linux-efibootmgr-examples It worked on my Lenovo P51 laptop. -----Original Message----- From: David Mehler <dave.mehler@gmail.com> Sent: Monday, July 27, 2020 11:24 AM To: blind-sysadmins <blind-sysadmins@lists.hodgsonfamily.org> Subject: [Blind-sysadmins] setting USB first in bcd boot order Hello, I've got an asus Motherboard with UEFI.
