The point is that you need to have EFI System Partition. So create one with 512MB. For detailed installation instructions check: Ubuntu 18.04 LTS Minimal Install Guide

The ' grub-efi-amd64-signed' package failed to install into / target/. Without the GRUB boot loader, the installed system will not boot.
This is the error I get every time I try to install 18.04. I have formatted the MBR and C drive of Windows and currently I have only
dev/sda
to install. I don't want to lose other data which I had in Windows 10.What should be the status of legacy mode and secure boot while installing Ubuntu 18.04?
I see only
dev/sda
instead ofdev/sda2
,dev/sda3
.What should I do?

Rinzwind over 5 years"I don't want to loose other data which I had in Windows 10." And that's why you make a backup before messing with your system.

user227495 over 5 yearsThanks @Rinzwind . My previous installation had a virus. Therefore, I thought it was not safe to move files before checking to another PC. My best bet is installing Ubuntu, reviewing files and then move them. How can I achieve " bootable USB should have a GPT ". I am not skilled. If you don't mind, can you please tell me what I should do in a sentence or two ?

Rinzwind over 5 years2 sentences? Not really. But the 3 topics I posted in comments should be enough ;-)
