I recently installed fedora on an external hard drive and it was working great. I plugged it in to my microsoft surface pro 3 and it booted up fine from the usb port. Well I proceeded to run sudo dnf update. Everything went fine. I opened the app section and there was 1 update available called Secure Boot dbx Configuration Update so I clicked on it and it installed and restarted my surface pro 3 device and it entered a grub page like it wouldn’t boot my fedora OS on the external hard drive any longer something had failed I was in some sort of grub> display but since I’m so knew to linux I didn’t know what to do so I restarted my surface and it rebooted asking for BitLockerKey it never booted up again something went terribly wrong . I’m able to access my surface original system just fine but I could no longer boot the fedora OS I had installed on the external hard drive. I need help on what I’m supposed to do for the Secure Boot dbx Configuration Update that messed up the installation boot loader config. This my first time trying to use Linux but I’m very curious in trying it. Please help! I tried creating another Live bootable fedora workstation using media writer but on my surface it wouldn’t read the flash drive it keeps saying unknown file something to that effect. and then making me enter the BitLockerKey every time I tried booting the live fedora usb flashdrive. So I’m not sure how I would even install fedora on my surface once support runs out in 2025 for windows 10?
This updates the bios secure boot area.
As I understand it, the update not only installs new valid keys into the database, but it also blacklists keys that are no longer valid (expired or have been deactivated).
For some devices it may even disable booting from DVD or USB and it is possible that was done for you.
I would suggest that you get into the bios setup menu on the surface pro and see if booting from USB can be enabled again.
