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:
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS

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.
Thanks
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.
Install edk2-shell:
sudo pacman -S edk2-shell
copy that to your esp-partition:
sudo cp /usr/share/edk2-shell/x64/Shell.efi ESP/shellx6…
