I created bootable usb pendrives using dd many times without any problems, also with SD-cards for the Raspeberry Pi.
But with the Linux Mint iso image something goes wrong and I don't know what.
Here's what I did:
1. I downloaded the iso image from a fast mirror using wget.
2. I downloaded the file sha256sum.txt from the downloadpage from the Linux Mint website.
3. I checked the integrity of the iso image using sha256sum, it's ok.
4. I copied the iso image to an usb pendrive using the command:
Code: Select all
sudo dd if=linuxmint-21.3-cinnamon-64bit.iso of=/dev/sda bs=4M status=progress && sync
I can't copy and paste that message obviously, and the pc switches off after a couple of seconds.mmx64.efi not found
mok manager not found
When I mount the pendrive and check the contents, I see this: (see attachement)
There's no previous installation of Linux Mint on the two pc's I tried (I'm using OpenSuse Leap).
There's no windows installed on these pc's and secure boot is disabled.
When searching for clues I found that many people stumbled over this problem but none of the suggested solutions
worked for me or the solutions weren't applicable to my situation.
Any ideas?
