I just installed Fedora 33 using a live USB while deleting the Windows 10 partition I had. After installation, Fedora didn’t boot. Lenovo splash screen flashes for less than a second and says “system bootloader not found”. Then it keeps restarting infinitely.
I tired booting into live CD, used efibootmgr and deleted “Windows Boot Manager”, “Fedora”, “Fedora” (Not sure why I had two Fedora entries. probably because my last install of Fedora dual booting Windows 10 wasn’t removed), deleted my SSD partitions again (using Gnome Disks), and installed Fedora for a second time. still same issues as before…
I also came across an old thread on Lenovo forums saying that it could be due to me using a docking station!!! I didn’t think that made any sense (specially since I installed Fedora 33 last month as a dual boot with Windows 10 and always docked without any issues). Anyways, I tried pulling the dock. Still no difference.
Secure boot is off.
Every install was done using default settings and automatic partitioning except I turned on disk encryption. Though I did try an install WITHOUT encryption and same issues …
Right now I’m booting into the Live CD and as you can see below, efibootmgr didn’t remove the entries I deleted before! Anyways, I don’t even understand efibootmgr that much (just followed an online guide) but I can’t boot into Fedora.
How can I do a fresh/clean install of Fedora on my SSD deleting everything and fixing my EFI boot ?
I’m on Lenovo ThinkPad T460s and my SSD is using a GPT
Here’s the output of efibootmgr:

If you no longer need dual boot, then just wipe the disk entirely.
In addition, upgrade and reset the BIOS/EFI firmware and reset the EFI boot settings specifically.
It should work with secure boot enabled and Intel RST disabled.
Since you want this to be a clean install without windows I would suggest you first, from the live USB, run parted on the disk and create a new clean gpt partition table. That will wipe out the existing windows garbage remaining on the drive.
Then reboot the USB, making certain that when you select it to boot in bios that you pick the UEFI version to boot.
Now you should be able to select the drive and use the automatic partitioning install. Remember that doing a clean auto install on 33 will use BTRFS for everything except /boot and /boot/efi. If you want something else you will have to use the custom install.
