There are 2 disks in the computer (Legacy UEFI mode):
(/dev/sda) SSD (2 partitions): efi, siduction 18.3.0 Patience - kde - (201805132121)
(/dev/sdb) HDD (2 partitions): KDE neon, data
Installed with siduction/calamares in automatic mode, and then completely updated: no errors.
After a system freeze/hard reset, the computer always boots from the HDD (KDE neon grub menu), although the SSD was selected as start disk in the computer boot menu (here via F11)!
(How can such a thing be explained?)
My real question:
Can I simply rebuild the boot sector on the SSD/efi partition using
# grub-install /dev/sda
or is there anything else you need to do?
Greetings,
Tom
