I have two problems related with each other. I use Clonezilla a long time for system imaging of all my computers and OS. I had no problem until now. I bought a new laptop Acer Aspire A315-55G with a NVMe SSD with preinstalled windows 10. When I use an USB with the latest Clonezilla on it, I can boot clonezilla but the internal disk is not listed in the kernel. Only the USB stick is visible as sda in dmesg.

I searched several forums and one hint was to use a live system like KNOPPIX to do more verification of the problem. So I downloaded the latest ISO of KNOPPIX and I created a bootable USB stick with that ISO using UNETBOOTIN under Windows 10.

When I boot this USB-Stick, I was asked to enroll a Hash for loader.efi which I did. Then I get to the following prompt:

What do I have to do now? How can I make the KNOPPIX usb stick booting to KNOPPIX? What do I need to enter at the boot prompt?

I have UEFI and Secure boot enabled (due to Win10). The Boot menu offers me the Win10-SSD and my USB-Stick for booting. But then I fail. So I think the BIOS/UEFI-settings are ok, but the configuration of the boot process for KNOPPIX image doesn't work.

You can try disabling secure boot when booting either Clonezilla or Knoppix for starters and see if that helps.

kilgoretrout's suggestion may fix it. You have to be careful playing with those keys if you want to keep windows.

Most of the nvme tend to have to have uefi enabled. They are not visable to csm emulation. If the Clonezilla booted then secure boot shouldn't be an issue. There are some cases where the bios can sort of lock the drive if Windows is there.
A nvme would not usually be a dev/sdx I'd think, it would be /dev/nme or something like that wouldn't it?

I'm not sure that all distro work equally well with any one usb creator.

UEFI can be vexing. Not NVME-related, just yesterday I found a UEFI PC (Asrock) that won't boot my everyday Knoppix stick to memtest, only Knoppix, and then only automatically, not accepting any options from the keyboard.

If you're not averse to using non-free software, and can't find a way to run Clonezilla, you could try the software I've been using exclusively for partitioning and cloning for two decades. DFSee includes binaries that use the same interface for DOS, Linux, MacOS, OS/2 & Windows, and (tries by default) logs everything done with it. I use edited/annotated logs to catalog hundreds of partitions across tens of PCs, besides for partitioning, cloning, sector editing and more. It's also part of my backup processes.

Another way to deal with such an issue is employing an old HD temporarily plugged into an SATA port to boot from and run Clonezilla or any other software you want to copy anything with, without any of its content possibly in a dirty, open or live state. This is how I have for years done BIOS upgrades that can only be done from a DOS boot.

I have tried to turn Secure Boot off but it doesn't change anything.

I have reseted everything back and made a shoot.

It says HDD0: NONE ????? That is really strange, because the HDD0 is there with Windows 10

What do I need to input when the boot-prompt is shown?

Which one should I use?

That's not a prompt. It apparently found nothing to boot from, so dumped you into UEFI BIOS setup. If you right arrow over to the Boot tab you'll likely see among boot device possibilities nothing listed because of a mismatch between configuration of the Kingston and the CSM setting.

Find CSM and Secure Boot there somewhere and report here those two settings, and/or try booting after changing them and/or any listed bootable devices, and saving the change(s).

There may be three or four good programs to make a usb. Etcher, rufus, linux live creator and unetbootin. Might look at pendriveliux.com for any that may help.
