I have a laptop with 2 ssds, and the one has win11 and the other endeavourOS. But I was trying some things with EOS and by mistake I installed EOS on the windows ssd. After that, I installed windows 11 again on that ssd, but when I tried to boot and normally have both options (linux and windows11), I only had windows. Then I installed EOS on the ssd2 and now I tried to boot and systemdboot showed only the linux boot option. How can I fix it so that I will have the option to boot into windows and linux? The
lsblk -f output is this:

With a search with keywords “dual boot windows”, you can probably start your fix. Here’s a couple I got:
Hi there. I have a laptop with an SSD which came pre-installed with Windows 10 in UEFI. I installed EOS in an ext4 partition that I created there (I made only one partition for everything). The partitions looks like -
EFI partition (default made by windows)
Windows C drive (default made by windows, shrunk by me)
Windows NTFS recovery (default made by windows)
An ext4 partition with EOS
Some problems that I am encountering -
When I created the installation usb, it didn’t boot up in UEFI mode…
Hey, was wondering if there was a well documented way on enabling secure boot for endeavour + windows dual boot using grub. I don’t mind switching to other boot loader if needed. I don’t really care about the security benefits, I simply need secure boot enabled for some applications on Windows 11 to work.
I’m sure they are going to appreciate it.
I saw your other thread the other day. Unfortunately I have no idea what might cause the issue.
You could perhaps wait a bit more and the bump the thread. Hopefully someone will come along and helping you out.
here’s a tutorial on how to get a Windows-entry in systemd-boot in case you use separate ESP partitions for Windows and Linux, with help taken from the
Arch Systemd Boot Wiki entry.
It is recommended that Fast Boot is disabled in UEFI as it can lead to several issues especially when dual booting - at least for me, it has no influence on boot time anyway.
sudo pacman -S edk2-shell
copy that to your esp-partition:
sudo cp /usr/share/edk2-shell/x64/Shell.efi ESP/shellx6…
