Administrators Hervé Posted December 7, 2020 Administrators Share Posted December 7, 2020 Did you try your Big Sur disk via F12 boot menu? That would normally be expected to add an entry in the UEFI boot list. Also check if you have Secure Boot set somwhere in your BIOS as you would probably need to have that disabled.

Moderators Jake Lo Posted December 7, 2020 Moderators Share Posted December 7, 2020 Boot with your USB installer, select your internal disk to boot. After booting into MacOS, mount the EFI partition of the internal drive as Hervé mentioned a few posts back. Mount the EFI partition of the USB drive, copy the /EFI/Boot and OC folder to your internal drive's EFI partition /EFI Reboot without the USB Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 7, 2020 Moderators Share Posted December 7, 2020 Looks like you have not completed the installation. Select 3.macOS Installer That should go away after successful installation and show your internal drive name. Link to comment Share on other sites More sharing options...
