April 9, 20251 yr I used to boot armbian on my Thinkpad X13S, but I didn't use Linux for 6 months. I updated bios few time in mean time. Now I'm no longer able to boot from USB drive and when I select USB disk in UEFI Boot menu. I tried few different images, I also tried to build it by myself, but still it doesn't pass UEFI select menu only return to it or boots windows. I also tried to factory reset UEFI, but still it doesn't boot. I have disabled fast boot in Windows. I used ballena etcher, rufus and dd to flash images. I tried: Custom image, built 20.03.2025(Kernel 6.14). Armbian_25.2.2_Thinkpad-x13s_noble_sc8280xp_6.13.0_kde-neon_desktop.img.xz Armbian_25.2.2_Thinkpad-x13s_noble_sc8280xp_6.13.0_gnome_desktop.img.xz
April 10, 20251 yr I think you might need to have Secure Boot disabled. It might be enabled by default in newer UEFI firmware.
April 10, 20251 yr Author I checked armbian images with disabled and enabled secure boot. Yesterday I tested official generic image from ubuntu(http://www.cdimage.ubuntu.com/daily-live/current/plucky-desktop-arm64.iso) and it is working, but it is creating bootable iso not image which is containing 3 parts free space, ARMBI_EFI and armbi_root. One of bigger difference is lack grubaa64.efi and mmaa64.efi on EFI directory in ARMBI_EFI in armbian image.
