I have a Lenovo ThinkPad (UEFI enabled) with Windows 10. I just have one hard disk. I am trying to install PopOs and have a dual boot option.

This link from PopOs has description regarding dual-boot installation. They have mentioned that we need to have three paritions Boot (/boot/efi), Root (/) and Swap. While installing PopOs, since I already had EFI secure partition, I selected this partition for Boot, and created new partitions for Root and Swap.

Installation was successful and when I rebooted and entered Boot menu, I can see PopOs bootloader entry has been added. But when I click on it, nothing happens. I am able to boot into my Windows though.


Had almost the same issue - difference was I actually created a new EFI partition at the beginning of the free space; but symptoms were the same. Here's the answer:


In short, disable secure UEFI boot in the BIOS.
