Did you just install kernel-cachyos and got hit by bad shim signature when booting? Me too. This is how I fixed it.
First, make sure you have Secure Boot with mokutil --sb-state.
Note, there's a second way of doing this by using sbctl, but I didn't want to wipe my Secure Boot keys.
Need help? Feel free to leave a comment below, contact me (@mikaeldui) on the CachyOS Discord, or send me an email.
