Ubuntu – Ubuntu is not booting on acer aspire laptop

bootgrub2uefi

I installed Ubuntu on my Acer aspire f 15 laptop using option "erase the disk and install Ubuntu". it erased the entire disk and installed Ubuntu successfully. but when I restart,I sow the message "no bootable device". I entered bios to change the order of booting but Ubuntu name is not there to change its order!
I tried boot-repair and it gave me the link and a message "please do not forget to make your BIOS boot on sdb1/EFI/ubuntu/shimx64.efi file!"

I don't know what does this message says and I don't know what action i should take.

note:Ubuntu is installed alone on my laptop.

any help is appreciated.

I also could not boot into my computer when I switched to UEFI. I fixed it by selecting "Boot from EFI File" in the BIOS and "Customized Boot" or something similar.

But I think it can be fixed if you put the EFI Partition to /boot/efi/. So in your case it should be in /boot/efi/EFI/ubuntu/shimx64.efi. It should then detect it normally.
