    I was very cautious with that tiny screw, realizing that my old eyes might not see it, if I would drop it to the floor.

    Yes, I connected my nvme drive (an m2 stick) via a PCI Express card to the motherboard. (And my computer cannot boot from it, but can use it for the root partition when booted from another drive.)

    Still not sure what size it really is, looks like M2, and search just finds other metric screws.

    I like the second link is $7.99 but $144.19 for expert installation.
    I found useful links specifying that tiny screw via your search pattern. Thanks @oldfred

    lol. If you can find it locally in a bin of a hardware store or, better, your local makerspace, it would be less than a quarter.

    ...sorry to bust in, all. I don't know what sub-forum this even is. I just read about the screw on the feed...

    As you were.

    The dimension of that tiny screw is related to the motherboard. There is certainly no standard size. The screw on my PCI-card has one size and the screw on the motherboard has a different size. The screw on the MSI motherboard isn't that common. I had the opportunity to find a replacement in a computer repair shop, but I didn't find one.
    However there is an advantage to use the PCI-card as you are able to easily remove the NVMe disk in case you want to install different systems on different disks. The big drawback is the speed. Average read speed is in my case limited to about 1GB/s on the PCI-card.

    OK I can use my spare NVMe Samsung 960 EVO to do some testing. I normally use dd to copy an ISO to USB, but it's good to learn some more methods.

    The M.2 nomenclature for the type of storage notwithstanding, I believe that "M2 screw" represents the size of the screw (M2.0 wafer head machine screw), which should have a thread length of about 1.5mm in most cases. These can be bought by the gross.

    Good news

    Please tell me if you need [more] details in order to start testing.

    yes, but... who needs a gross of screws? What are you going to do with the other 143? I guess you could start using them for odd projects, if you bought an m2 tap and had something to tap into...

    ...it doesn't matter much...

    There is an issue though in that there's more than one common threading for an m2 screw, and we're not certain it's an m2 even. You need calipers and a thread gauge: about $140.00 for quality versions, maybe $40.00 for inexpensive but functional clones from China...

    Edit: It's not just thread length, it's thread spacing... you buy different taps for different screws with different thread spacing. Using the wrong threaded screw is liable to strip the threads, break the screw, gum up the works. Quite likely in this instance, you would strip the threads and make the screw non-functional. It would vibrate loose in the case later, and roll around and annoy you 'till you found it three years later while dusting the fans... Not a big deal, in the grand scheme of things

    So far so good
    Now it's only to select the NVMe drive and see if it's OK to boot.

    Now I will reboot to see if it's working.

    Worked to boot from the NVMe in legacy mode. Perhaps there is a setting in BIOS to boot from the EFI partition.
    Perhaps this wasn't the usecase you wanted. When I start the installation I'm able to install Ubuntu to either sda, the Samsung 250GB SSD, or ScanDisk Cruzer Contour USB.

    What I want is testing mkusb and Calamares:

    - Test if the tool can make a complete installation into an nvme drive so that the computer can boot from it
    - If it works, fine, that's it,
    - Otherwise help debugging by repeated tests with modified versions of the tool until it works.
    Yes, I can install using Calamares and it does boot. Unsure about meaning of 'mkusb'. I install ubuntu.iso using hybrid method into my usb flash, then boot into that usb, then install from Calamares into my m.2 ssd.
