Installation of ubuntu to replace windows

I’m trying to install Ubuntu on a windows desktop. I’ve created a bootable usb stick and adjusted the boot menu, but I get an error message, something like:

Could not create MokList: Volume Full
Something serious has gone wrong.


Any help in resolving this would be appreciated.

Sorry, not enough detail.
Have you deleted Windows? or are you installing Ubuntu alongside Win on a separate partition.?

Where did that error message come from..
What were you doing when it gave the message.

What do you mean by " adjusted the boot menu" ?

Have you done the install? Did it complete?

I have not deleted windows - I want Ubuntu to replace it.

I adjusted the boot menu in UEFI/Bios settings to make the bootable USB the primary boot.

On restarting the PC, the boot did not start and the error message appeared at that point.

OK… you are having problems booting the USB drive
How did you make that usb drive?.. I assume you downloaded an Ubuntu iso file, and then copied it go the usb drive somehow?

It may be that the bios is trying to do a legacy boot and your usb drive requires a uefi boot… or the other way round. Did you get a grub menu?
or, it may be that you made the usb drive incorrectly.

If you are going to put Ubuntu on the partition Windows was on, I would advise you to reformat that partition to an ext4 filesystem… because the ntfs filesystem used for windows is not suitable for Linux.
You can use gparted to do that, or you can ask the Ubuntu installer to do it.

Do you understand disk partitions? If not, your simplest option is to use the Ubuntu installer and tell it to ‘use the whole disk’ for the install.

I followed the instructions here Install Ubuntu Desktop - Ubuntu Desktop documentation

to create the boot drive.

Did not get grub screen.

I’ve done this procedure before on other PCs without problem. As you suggest, the installer handles the necessary disk partitions.

Thanks for responding, Neville.

With a further bit of research, I found a solution.

I needed to delete the Secure Boot Keys in UEFI/BIOS.

Having done this the boot from the usb stick went smoothly.

I was just asking Copilot what the issue might be and it looked to be UEFI related. Glad you found the solution.

Great you solved it.
The error message “Volume full” was not very helpful.
I was starting to think the usb port might not be working.

Opened the box, took out my new (refurbished) Optiplex 7050, plugged it in, watched Windows 11 boot. Downloaded and installed Rufus. Downloaded MODICIA OS.
Loaded MODICIA on USB with Rufus.

Restarted to access the BIOS. Disabled Secure Boot.

Restarted, pressing F12 to boot from USB. Installed MODICIA to replace Windows.

Restarted, installed Vivaldi, installed Proton Pass, started up ItsFossCommunity.

Twenty minutes, with a bathroom break.

Well done Bill.
It shows how easy a Windows-to-Linux conversion can be.
Do you think a user who had only ever used Win could do the same , with the right tutorial as an aid?
How do we get this out to potential converts.?

How important was Modica? Can you do that with Mint or MX ?

I haven’t seen an installer that won’t take over the entire target disk/partition. Calamares is superior because it has the option of total takeover, side by side, or replacing an existing OS.

Gazelle installer , used by MX and antiX , has those options too, plus custom.

We need a discussion of installers
