I've been reading lots of posts about how to create a bootable usb and how to install but I haven't been successful.
I've created the "bootable" usb following this guide from Ubuntu site.
When I boot with Refind, my usb is not even listed.
Pressing alt/option key when rebooting I manage to have my usb listed and boot. However I get the following error message:
Could not open "\EFI\BOOT\fallback.efi": 14 error: file `/boot/' not found.
However, a grub screen appears with the options for:
- trying ubuntu without installing
- check memory
But after choosing any option I get stuck with a black screen.
Thanks for your help.
