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
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.
