Today I decided to install Ubuntu 18.04.1 LTS, but never used it before (used only win7x64).

First time, after reading a number of topics, I didn't pick "erase and install" but tried to set it manually.
Everything seemed great, but an error appeared (forgot to take a photo) only remember a word like gpub or something like that.
Then I reinstalled it through the "trying mode" by clicking on the pic (Install Ubuntu).

In bios menu I saw this

(probably some of them are unnecessary)

So the question is: "Is it okay to have 2 Ubuntu options and UEFI OS as well?"
I don't mind reinstalling it again, just want to fix it.

I used a USB-card to install it.

Thank you

  • If you have UEFI Secure boot off, you have two Ubuntu boot options, shimx64.efi and bootx64.efi. Shim is for UEFI Secure Boot, grub is for standard UEFI boot. And hard drive boot is usually /EFI/Boot/bootx64.efi or a fallback boot. Usually orginally a Windows boot file copy, but Ubuntu may make it a shimx64.efi copy. You can try it to see what it tries to boot. – oldfred Sep 2 '18 at 18:27
