I know there are a bunch of questions similar to mine, but I don't know what went wrong and how to fix it :(

Now, some back story. I have managed once to install Ubuntu with my Surface Pro 4 on an micro SSD card a few months ago as a test. After the test was successful, and after a few months, I bought a proper SSD card to properly use it.

But now grub doesn't work any more.

The checklist:

  • Disabled secure boot
  • Make sure that the EFI files are in the first partition of the /dev/nvme* drives, not on /dev/sda
  • Then tried to use boot repair which seemed only to understand the /dev/sd* partitions (log here).
  • Attempt to reinstall Ubuntu tells me clearly that the partition already has Ubuntu there.
  • Formatting the dist and reinstalling Ubuntu, still no luck
  • Trying 18.04 and 19.10 and again still no luck

I don't know what to try next...

I managed to fix this issue like this:

  • reinstalling/clean installing ubuntu just to be on the safe side
  • boot into windows (linux still doesn't boot due to grub issues)
  • install rEFInd following the official instructions
  • reboot, and not only it works, but as a bonus I have a nive graphical UI to select operating systems
