G'day all
BACKGROUND
Peer, you can tell me anything I have wrong here, with the usual "quote and answer"
Member @Peer has a relatively new laptop he got for his birthday at end of July last.
Before that he had another laptop and had begun his journey in Linux (he also has a Raspberry Pi), starting with Ubuntu, which he still uses.
Since that time, he has also started exploring Debian, another good choice, IMO.
THE PROBLEM
As Peer's Thread Title suggests, he has a problem with the bootloading on his Debian install.
Peer has Windows on, I think, both laptops, the old and the new ... Is that Windows 10 on each machine, Peer?
With his Ubuntu, he gets a Grub Menu, which features Ubuntu, Debian and Windows. He can boot the Debian from there, and there only.
Well, yes it does, that was a part of the install, but does it have a Grub Menu by itself, now?
It is important to note the difference here -
GRUB is the GRand Universal Bootloader, and is installed with most Linux.
But the Grub Menu is what we see to choose what to boot into - Linux, Windows or other.
WHAT WE HAVE LEARNED ABOVE
Through questions, we have established that neither the Ubuntu nor the Debian is a full install to Peer's hard drive.
Windows is still the only OS installed on his laptop.
Peer has performed a full install of Ubuntu, but only to a USB stick, not to his HDD.
He has performed a full install of his Debian, but only to a USB stick, not to his HDD.
MY THOUGHTS
Ubuntu and other Debian-based Distros have been actively churning out updates in the last few weeks, involving:
Debian itself, which Peer is also using, not so busy.
Peer has had both sticks inserted on his computer when one of these "events" has occurred, and Ubuntu has been in charge of the Grub Menu, or it has been affected when he ran updates from it.
Because Ubuntu is a full install on a stick, when Grub is updated, Peer's computer will treat it a bit like a full install, to the point of recognising it in the BIOS.
If his Debian has not been treated in the same way, it will not get its own Grub Menu, and the BIOS will not recognise it as a full install, that can be booted through his Setup Utility.
OPTIONS
Can be done, but the first time he boots from the Ubuntu stick, it will show the Debian entry, but not boot to it, as he will have to change the UUID in /etc/fstab to reflect the UUID of the new Debian install.
3. ALTERNATIVE
Peer, are you aware that you will not ever get the performance and speed that Ubuntu and Debian can deliver with your current setup?
Doesn't matter if they are USB 3.0 or 3.1 sticks to USB 3 ports or whatever?
You can only get that if each of Ubuntu and Debian is fully installed to your HDD alongside Windows.
Which prompts me to ask -
Do you want to do that? Are you aware that it can be done?
And of course - do you need to check it with Mutter und Vater?
Think about it and let us know.
And don't be afraid to tell me I have made a colossal "booboo" in my understanding, here. Just set me straight.

That's how you become a Wizard ... CRASH, BURN ...AND LEARN

THE PROBLEM
As Peer's Thread Title suggests, he has a problem with the bootloading on his Debian install.
I always have to use the grub on my other Ubuntu installation to bot Debian.

MY THOUGHTS
Ubuntu and other Debian-based Distros have been actively churning out updates in the last few weeks, involving:
- New Kernel updates
- New efi-signed packages
- New Grub 2 updates
- New firmware updates
- other, can include shim and shim-signed updates

OPTIONS
- Peer can get his Debian running through his Ubuntu install, and then run
Code:
sudo update-grub
- He can overwrite the Debian stick and reinstall the Debian again (without the Ubuntu stick in place), and once that is completed and running successfully, he can update grub with Ubuntu in place, and reboot, and he should get a new Debian-controlled Grub Menu also featuring Ubuntu and Windows. *Not Desirable, see below
- Alternative
Can be done, but the first time he boots from the Ubuntu stick, it will show the Debian entry, but not boot to it, as he will have to change the UUID in /etc/fstab to reflect the UUID of the new Debian install.
