After Install of Ubuntu 24.04 onto a drive with Win 11, I get everything except the GRUB menu at reboots. I installed Boot Repair, ran the diagnostics. The app did find no Grub and the suggested repair would install a GRUB.
I must use the hardware Quick Boot menu that shows Windows, Ubuntu and Enter Setup. If I select the Ubuntu option then I get the GRUB, the choices of OS or Memory.
If I go into UEFI firmware , Boot Order I don"t see anything Ubuntu. I see Windows, Hard Drive, CD, etc.
What I’ve Tried:
This is the second miniPC with a dual boot and it failed to include a GRUB startup. The first miniPC did install a GRUB startup and I think the only difference was I Tried Ubuntu from USB stick and then I installed.
Therefore, it looks like a UEFI option to set OS priority
In your UEFI Setup, do you have a Boot tab?
Then, can you see UEFI Hard Disk (or NVME) Drive BBS Priorities or similar?
Your suggestion lead me back to the EUFI, Boot tab and at the bottom was another sub-menu that fetched a popup dialog menu to cycle through the choices shown on the Quick Boot Menu. In other words, I could provide Ubuntu as a choice and then select it in the tab to always start from there.
Just crazy. Two identical miniPCs and this 2nd dual-boot install is a little different. Now, if I could just get my all-in-one network printer to be recognized. It was a bear on the first miniPC.
And, BTW, in Germany around New Years was “Dinner for One”, an old TV comedy clip from Great Britain, that ran very often on every German channel , ad nauseam, as a joke. The clip is on youTube.
