No GPT During Installation, No Boot Options

Hi @npaladin2000
Again this laptop is driving me crazy! I tried to install again… went fine to the end.
Rebooted. Nothing.
So, I thought to try install something else.
Connected an external DVD, power on to start installing…

I swear I do not know how did Grub appear and booted.

Maybe I should change to systemd-boot to be sure it will boot!

I know there is a tutorial @dalto made [Tutorial] Convert to systemd-boot
and I successfully used it and changed to systemd-boot.

But as this laptop is quite old, (maybe BIOS not UEFI, I saw something in BIOS saying Legacy and it is on) so I do not want to go and do instructions given by @dalto blindly.

It notified me there are updates but I didn’t update anything!

So, what should I do now to be sure I will be always booting (I have a gut feeling that systemd-boot should be better in my specific case. Or just leave Grub as is?)

Your valuable help is highly appreciated as usual.
Thank you.
