Yes exatly I’m wondering if Calamares is not blind with your M.2 disk or recognize it as sda not as nvme0np !
i did exactly this Modifying grub installer, to fix problem
Could you check there about someone who had problem with M.2 and Calamares :
my m2 appears on calamares partitions tho
Yes I saw on your picture, I checked it again and I don’t see the EFI on the left of Storage Device. So you didn’t boot the UEFI USB key but the USB key.
Look on this link for exemple on the partition picture, you have to see EFI on the left top :
Well it does (i think?)
This is what mentioned before. It will automatically think it’s /dev/sda for grub and it will not identify the right drive if you don’t select it and os-prober has to find it.
i don’t know why it try to look for /dev/sda when i arch-chroot into /mnt (which is mounted in /dev/nvme0n1p2)
Have you tried even once just installing it without creating manual partitions and instead create GPT and let it delete all the partitions Then let Calamares install it using erase disc with swap. Or have you just tried every time to do manual partitions and changing things?
i think i tried both, will retry right now, i give you ETA in 5 minutes
It fail at the same steps again 
So I have a question then. Why not pop in a fast SSD drive and install it on that instead. It probably won’t give you an issue. Or did you say before that you were able to install Arch and it worked? You could then just add the endeavor repo and add the few packages.
can’t make DE works in arch
Are you able to add an SSD drive? They aren’t very expensive.
well need to buy one, open laptop and stuff, don’t really have time meh. but is it really only a m2 drive problem? xD
What brand of m.2 drive is it? I have a corsair MP500
i have this one : SAMSUNG MZVLB512HAJQ
will try to install arch since it’s the only way for the moment, except windows+vm+wsl
need to have stable and working things in 5 hours
I thought you said Arch desktop doesn’t work?
Hi @anon64481721,
could you check this post, they used another way than --removable and it works :
Anyway, I have created the /boot/EFI/BOOT directory and pasted /boot/EFI/arch/grubx64.efi to /boot/EFI/BOOT/BOOTX64.EFI. Is this the same as if I’d had used grub-install --removable?
