I installed Ubuntu 19.04 on my windows 10 machine this weekend with no problems. On my first windows boot since the Ubuntu install I got a memory management bsod after which windows booted up fine. However I havn't been able to successfully boot up Ubuntu since. I get a flashing cursor. I can hit ctrl+alt+f2 and log in, but I don't know what to do after this. I tried using boot repair which changed the boot menu but hasn't fixed the problem. The URL it gave me is http://paste.ubuntu.com/p/DYqmGMzQWc/ It also told me to make my BIOS boot on sda2/EFI/ubuntu/shimx64.efi file, but I'm not sure how to do that. Thanks for any help!

Update: I tried purging and reinstalling grub2 using instructions from here https://help.ubuntu.com/community/Grub2/Installing and I keep getting stuck with an error message "dpkg: unrecoverable fatal error, aborting: files list file for package 'linux-image-generic' is missing final newline" Is this related?

This is more ongoing debugging session than an answer

Your Linux is up

If c-a-f2 gives you a login... Which means if

  • logout (ctrl-d) followed by again login works
  • ls works
  • apt/apt-get work

Then

  • shell is working
  • basic utilities are ok
  • kernel is ok
  • grub is ok

Currently it looks like

  1. Apt (data) is not fine
  2. X (lightdm) is not starting ok
  3. Efi issue

I'm not up to recent Ubuntu...Here's the older solutions. You may want to open new focussed questions

  1. apt-get update... apt-get -f
  2. service lightdm restart...check X logs
  3. Image/text-copy/photograph efi message
