How can we disable secured boot with rhel/centos ?
by ranshalit from LinuxQuestions.org on (#4TPRS)
Hello,
How can we disable secured boot with rhel/centos ?
I have some strange behavior with centos8 which I did not have with centos7...
when I compiled same kernel and installed it it worked perfectly.
After some resets I made some new configuration in kernel and on the new install I got:
"
error: ../../grub-core/loader/i386/efi/linux.c:208(hd0,gpt2)/vmlinuz-4.18.0-51.el8.x86_64 has invalid signature.
error: ../../grub-core/loader/i386/efi/linux.c:93:you need to load the kernel first.
Press any key to continue...
"
I checked BIOS and "secured boot" entry in BIOS is DISABLED !
What is going on ? Why it still give this error ? Why does it think there is a signature error ?
I can't remove this error, and boot.
I also see that this issue is "on progress" in rhel issues of centos8:

Thanks,
