I am trying to dual boot a computer with pre-installed Windows10. My goal is to install the latest version of Ubuntu18 in a partition. I have followed the instructions I found. I

  • unflagged "turn on fast startup"
  • unflagged "secure boot"
  • created an installation USB key
  • freed some space from Windows disk management
  • rebooted and selected the option "Install Ubuntu"

everything went on smoothly until the end of the installation. Then I was asked to reboot but, as soon as I clicked that option, the computer became unresponsive. I may have done a terrible mistake here because after some (long) time I decided to switch off and back on.

Next, grub prompt appeared and it was impossible to enter either ubuntu or Windows

After some unsuccesful attempts, I just used F11 and managed to go back to Windows (which works just fine)

Now the system seems to ignore the partition or grub if I reboot. my questions

  • did I mess everything up when the system seemed unresponsive or something had already gone wrong?
  • since the installation seemed to be succesfully completed, is there a chance to get the grub prompt back and fix things from there?
  • I am quite tempted to just delete the "broken" partition from Windows and repeat the passages, but I may solve nothing and make thing worse... or maybe not?

Any suggestions? Thank you in advance

edit: by reboot+F11+ubuntu disk I can get back to the grub prompt. then if I type

ls (hd0,1)/efi/ubuntu/

I get

./ ../ grubx64.efi shimx64.efi mmx64.efi bootx64.csv grub.cfg
