I desperately need help after trying everything I could find online and understand on the matter.

Here's my goal :

  • Installing Ubuntu 20.04 alongside Windows 10 on a LENOVO ideapad y700.
  • One hard drive for windows 10, one for Ubuntu 20.04.

Here's what I've tried :

  • Windows 10 is preinstalled, I used Rufus to create a live usb key with ubuntu 20.04 in UEFI mode.
  • I deactivated safe boot mode, fast boot in the UEFI, as well as the hibernation mode with the command powercfg /hibernate off in a windows terminal.
  • I deactivated the Fast Startup mode in the control panel.
  • I installed Ubuntu (seemingly) successfully and rebooted my computer.
  • I changed the boot order in the UEFI
  • I set up a password for the UEFI

The issues

At first, the boot order between windows and Ubuntu kept getting reset in the UEFI, I could only access Windows 10. I tried the boot repair method, I got the message Boot successfully repaired and I have a report on this URL : https://paste.ubuntu.com/p/gVVY6BSr7b/. Now the order is not reset anymore, but when I boot choosing Ubuntu, I have a big blue message : enter image description here

Before getting this message, I do have a grub command line showing, but no idea what to do with that :

I don't know what else to do at this point. When I connect the live usb key to see if my installation worked, if I try to reinstall ubuntu, it tells me that Ubuntu is already installed so it looks like the installation is correct ...

here's a few pictures from inside my uefi if that can help you help me :

EDIT : I just saw I had a new disk appearing under windows containing the following files and folder, can I do something with that ?

This answer seems interesting in my case but I'm not sure how to apply it to my specific case ... What do you think ?

  • Windows may see the FAT32 ESP - efi system partition with Ubuntu's boot files. You have your NVMe drive as the very old MBR(msdos) partitioning. Ubuntu lets you use that for UEFI or BIOS where Windows only uses gpt with UEFI boot. But some UEFI may be particular also. May be better to convert to gpt. Note conversion normally erases entire drive, so backup your NTFS data partition also. Converting to or from GPT - must have good backups. http://www.rodsbooks.com/gdisk/mbr2gpt.html But since all UUIDs change you will need to reinstall. – oldfred Nov 02 '22 at 02:46
