Hello,
The common issue with dualboot windows + ubuntu:
"error: bad shim signature"
At (hd0,gpt4) linux /boot/vm... error: bad shim signature.
... so you just need to enroll your hash of vmlinuz linux kernel into the machine
then, boot a linux, that works and do: mokutil --reset
enter pass for instance : user
Code:
apt-get install pesign
Steps to Enroll the Kernel Linux:
1. Enroll the hash of kernel image (the kernel image needs to decompressed first otherwise pesign can't recognize the hash) using
mokutil:
here we go :
Code:
mokutil --import-hash $( pesign -P -h -i vmlinuz-5.19.0-26-generic | cut -f 2 -d ' ')
The command
shows the MOK variable.
2. Reboot and continue the hash enrollment in MOKManager
3. Try to boot the kernel
DMESG to check that your modules are all there.
ip addr and wifi is there
