Lubuntu or Kubuntu?

[MarkS]

Why aren’t you selecting *Ubuntu from the Grub menu? That is the Kubuntu entry you are looking for. Installing Kubuntu doesn’t create a *Kubuntu entry in Grub.

Because when I do that Ubuntu came up. Thanks, I know what you mean. Seems like the latest version of whatever installation is is called Ubuntu on the Grub menu. Anyway, all working now.

Okay so I entered BIOS and moved UEFI USB Device to the top of the boot sequence and rebooted. Kubutu started up this time but crashed unless I started in safe graphics mode. Installation went fine. Thanks for the pointers everyone!

Yes, I select "Grml Rescue System..." since that is what Smart Disk Creator added to my Grub. All other entries boot normal. Yes, I can change the order in BIOS but makes no difference.

So, to be clear this is what you see when you boot using the USB, correct?

*Ubuntu
Advanced options for Ubuntu
Windows boot manager
Ubuntu 20.04.5 LTS (20.04) (on /dev/sda9)
UEFI Firmware Settings
Grml Rescue System (lubuntu-17.10.1-desktop-amd64.iso

If this is correct, then the USB's (and the DVD's) Grub boot loader is detecting the "Grml Rescue System" as something already installed or present on your system, along with your Windows OS and 20.04 install, the Startup Disk Creator tool is NOT putting this on the USB
Select the Ubuntu entry at the top to boot into the 22.04 installer.
You can ignore grml for now.

My quick guess is that this some utility was used to create a menu entry that can boot an iso image directly from a hard drive. This is a thing that can be done
EDIT:
yup grml-rescueboot :

This is a bit old, but it sure looks familiar.....

"So your computer bios seems to want to boot this Grml rescue system entry with a higher priority for some reason?
You can change that of course"

I'm looking for the initrd.log so I can see what's happening at boot up. Forget how to use the "su udpatedb" and locate commands.

*Ubuntu	<<< This is for the Kubuntu 22.04 installer
Advanced options for Ubuntu	<<<< so is this
Windows boot manager	<<<< Obvious
Ubuntu 20.04.5 LTS (20.04) (on /dev/sda9)	<<<< This is Kubuntu 20.04
UEFI Firmware Settings	<<<< Open BIOS settings (may/may not work)
Grml Rescue System (lubuntu-17.10.1-desktop-amd64.iso	<<<< No idea what this is

What you have above is what the *buntu installer USB will look like, as it is all Ubuntu as this low level.

The other entries below 'advanced' are for other OS entries that the USB stick's own Grub detects when booting, plus the UEFI firmware entry (your BIOS settings)

So your computer bios seems to want to boot this Grml rescue system entry with a higher priority for some reason?
You can change that of course

Also note that each *installed* Linux OS will have its own separate Grub boot loader.
And each grub can boot all the other installed OSs, if they have been updated (usually when its kernel gets an update)
So it usually a good idea to set your desired Linux OS as the main boot OS in the Bios, and check every now and then, as Windows updates often changes this.

Snohog:

Yes, exactly. That is the new Grub entry created when I used Statup Disk Creator pointing to Kubuntu 22.04.01 LTS amd64.iso

[Snowhog]

Grml Rescue System (lubuntu-17.10.1-desktop-amd64.iso

Seems to me, that this is what is getting booted?

[MarkS]

There must be a log file that tells me what's going on during boot. Initrd.log or something?
These are my boot options in grub.

*Ubuntu
Advanced options for Ubuntu
Windows boot manager
Ubuntu 20.04.5 LTS (20.04) (on /dev/sda9)
UEFI Firmware Settings
Grml Rescue System (lubuntu-17.10.1-desktop-amd64.iso

I have Kubuntu 20.04.5 LTS installed on sda9.

The Grub selection Grml Rescue...boots the dvd or USB. What should the Grub entry look like for Kubuntu 22 ?

Not booting off the hard drive.

We're suggesting that the boot from the USB or DVD fails very early, so the firmware tries to find another drive to boot from. Other than that I can't imagine how the DVD could possibly get you anywhere near anything that says "Lubuntu".

Not booting off the hard drive. I can chose where to boot in the BIOS. I can boot off optical drive or USB. Same result. Boots into a Lubuntu window manager.

[arsivci]

I suspect you're booting from the hard drive, not from USB. Most UEFI PCs do not allow booting from USB automatically. For instance, in my Lenovo I have to repeatedly press F12 to choose the USB stick to boot.

jlittle:
I use the Startup Disk Creator to burn the Kubuntu iso to a 256gb USB stick. I may have used this once before for a Lubuntu installation years ago. I would think the Startup Disk Creator would erase and reformat but maybe not. When I boot, Grub screen sees the USB sick as Lubuntu not Kubuntu. I have the same problem when booting directly from the DVD. It's a fresh Kubuntu iso with correct sha256 checksum. It boots into a Lubuntu window manager.

(When you say "installed to USB stick" I now presume you meant you "wrote" (or "burned") it to a USB stick; installing Kubuntu to a USB stick is quite possible these days, and initially that's what I thought you'd done.)

To boot from the Kubuntu iso, what do you do? Do you press F12 or F8 or something to interrupt the normal boot, then choose Kubuntu from the choices you see?

I suspect your computer is booting in BIOS mode, and grub from some ancient Lubuntu install is in the MBR gap of a BIOS/MBR hard drive in your system, or something like that. You need to boot the computer in UEFI mode to install Kubuntu 22.04. I suggest you look closely at the choices I referred to above; there may be several Kubuntu ones, and sometimes the one you want has to be found by scrolling down. Perhaps you can disable "compatibility" mode in the firmware. If I'm right and you're not installing to the old drive, it might work to disconnect that drive temporarily.

Writing a Kubuntu 22.04 iso to DVD sounds like an achievement. That the DVD does the same is evidence that the boot moves on to another drive.

[MarkS]

I may have used the USB stick to load Lubuntu 5 years ago. I used Kp3 to delete the old partitions on the USB and re tried Smart Startup but same results. Boots with a Lubuntu window manager with a Kubuntu file folder and "Install Lubuntu 17.01" icon.

The odd part is I can burn to a DVD and get the same result so not the USB stick. The Grub selection I get is "Grlm Rescue System (lubuntu-17.10.1-desktop-amd64.iso. I get no selection for Kubuntu. Sounds like Grub may be the problem?
