i am not able to choose between OS
Cheers!
I have set up an UEFI dualboot on my X220 (systemd-boot). Everything works fine and both OSes boot up. The only Problem to solve is getting the bootloader to Show me both OSes at once. Right now I have to hit F12 to choose the SSD to boot from directly - OSes are separated.
I have also tried to Mount both EFi partitions to /boot, generating a new fstab and start bootctl install, but it didn´t help. When I choose either EFI Partition for a bootloader install, the other OS isn´t recognized.
Has anybody encountered this before and is willing to shed some light?
Thanks in advance!

Re: i am not able to choose between OS
This is rather unclear. Are you saying that, if you do nothing, Arch boots normally, but you have another OS installed on another drive that is not being recognized?
If so, you just need to write the relevant configuration to chainload its bootloader (or boot it directly if that is possible depending on how you have your drives setup).
If not, you're going to need to clarify a bit more.
All the best,

Re: i am not able to choose between OS
You should be using only one EFI partition for both OS's, otherwise selecting the drive from your UEFI is the only option.

Re: i am not able to choose between OS
Yes, thats the exact problem Halos. I tried the following setups, with efi mounted to /boot and generated fstab:
- setup with arch's efi mounted -> arch boots fine
- setup with W10's EFI mounted -> W10/boots fine
- setup with both efis mounted -> either OS boots fine, but has to be chosen using F12
I haven't made a config for systemdboot because I actually dont know what to put in for W10.
Also the wiki and other resources keep saying, that systemdboot detects the efis automatically.
While writing this I remember that I didnt install
osprober. Will try this and come back then.
What to put in the config for W10?

As slithery notes, because you have elected to use two EFI system partitions then it is not possible to dual-boot with systemd-boot (although you may be able to do this with GRUB or rEFInd).
If you share the Windows-generated EFI system partition with your Arch system (mounted to /boot) then a Windows menu entry will be generated automatically by systemd-boot.

Re: i am not able to choose between OS
Hi, sorry for the late reply. I have tied you solution @Head_on_a_stick. But W10 refuses to update and gets a bootloop then. I will just stick with hitting F12 and choose the SSD to boot from.
