No Bootable Device Found

Hi, I've installed Windows a million times but I've never had this issue before. I was reinstalling Windows 11 on an Intel NUC Pro 13 (now Asus) using a USB stick. After the first restart, I got this message message "no bootable device found". I removed the USB drive but got the same message. The SSD is present in the bios. I tried reinstalling but I can't get the usb to boot anymore. Nothing happens when I click on the usb or SSD after loading the F10 boot menu. It just stays on the boot menu screen. I Also tried loading bios defaults.

Intel NUC13 Pro i5 (NUC13ANHi5)
32GB DDR4 3200
1TB Seagate NVME SSD.

Check if CSM / UEFI is enabled and switch between the two.

The laptop might also show the USB twice, as "USB" and "UEFI: USB", make sure to select the correct one. UEFI ideally is the one you want to try first.

UEFI is the only option.

There is only one USB option. It only supports UEFI.

How did you create the USB? Try using Rufus and see if it can boot from that.

I used the media creation tool from the Microsoft site. It booted fine the first time. Not having any luck with Rufus too.

Finally managed to get Windows installed. I went into the bios and disabled secure boot and now Windows 11 proceeded to install. After the install was complete, I re-enabled secure boot. I'm not sure why this happened in the first place but at least I got the NUC working again.

Now that you mentioned that, same thing happened to me last week with a Lenovo laptop when I tried doing a fresh install of W11 25H2. For some reason it refused to boot from the USB until I enabled "Allow Microsoft 3rd party UEFI CA" in the BIOS. Then after following the install steps it wouldn't boot from the SSD. Turning off secure boot also fixed it, then I allowed Windows to fully update, turned secure boot back on and it worked.

I'm curious if it's related to this but the old certificates still have a couple of weeks until expiring: https://forums.overclockers.co.uk/t...tificates-aging-out-on-june-24-2026.19012463/

But weirdly enough the BIOS did show it had the 2023 certificates, but after I enabled secure boot back on, Windows Security was still reporting it was still using the 2011 certificates, so it hasn't swapped over to the newer ones yet.
