Boot problem with Kubuntu 23.10

Hi all,

Long story as short as possible:

Lenovo Ideapad 3. I had windows 11 on SSD. Installed Ubuntu on HDD, dual boot with windows on SSD. Later decided I like Linux, no need for Windows. Installed Kubuntu on the SSD. Worked fine. Manually deleted partitions etc on HDD, made it one big partition for backintime and timeshift to use. All is good.

Now, when booting the laptop, it will start (I can hear the HDD spin up, and I see the screen come on, but nothing displays) then the laptop switches off, and immediately comes on again as above. This happens three times, on the fourth reboot the system starts normally. I have tried changing every single setting in the BIOS, no difference. I do not know much about grub, it seems OK to me, but the problem is probably there.

Please, does anybody know what I can do to fix this?

Thanks!

Some info below:

There is a lot of stuff in /boot/grub/grub.cfg, let me know if I should post it.

surewhynotlem,

Old advice. Might be out of date. But when I had issues like this it was because my master boot record was on both drives, but the second one was first in the BIOS boot order. It had to cycle through that failing before it tried the MBR on the correct drive

Dakspyker,

I think it is something like this, it looks for something before timing out and moving on to the correct drive. I don’t know how to fix it though. I’ll start with man journalctl as was suggested elsewhere. Thanks!!

PlasticExistence,

This tool might make fixing the issue easy:

sourceforge.net/projects/…/download

It will scan for Grub installations and attempt to fix errors. It’s possible to fix things manually, but this is often easier.

I recommend disconnecting the HDD to prevent installing anything on it, then repair the boot / EFI / Grub issues, then reconnect the HDD. That way you know for certain all linux partitions are on the SSD.

kaleid,

Check for errors in journalctl. If not sure what options/ flags, start with ‘man journalctl’, this will show you manual page for systemd log.

Dakspyker,

thanks, I’ll do that!
