On laptop based on i5-8250u efibootmgr works fine (all kernel versions) 2. On systems based on LGA1155 socket (i5-2500k, i7-3770): - kernels 5.10.x: efibootmgr does not work, directory /sys/firmware/efi/efivars is empty - kernel 5.8.0-2: efibootmgr woks as expected On 5.8.0-2 i get: # lsmod | grep efi efivarfs 16384 0 efi_pstore 16384 0 efivars 20480 1 efi_pstore There is no efivars.ko in 5.10.x. Maybe that is the problem? -- Regards Greg
