If you want to see the installed kernels use clr-boot-manager list-kernels. You can set the default kernel by using clr-boot-manager set-kernel xx.xxx.xx.x.
If you want to see the list of kernel available, please modify the bootloader time out in clr-boot-manager set-timeout 20.
thank you for the quick response.
I did all that and it worked on at least one of my other machines.
But on my NUC10i7FNK there is just one entry saying “Clear Linux OS”, there is no kernel name/version shown at all. set-timeout values are ignored and set kernel values in the loader.conf do not work either.
I already tried CBM_DEBUG=1 clr-boot-manager update but there were not errors.
