I just finished dual booting the latest image with Windows 10. Very smooth experience and everything worked fine. Amazing job! I am from the Manjaro world where I always used the root tip command to enable grub with this command as explained in the Manjaro WIKI
The fact that you ask, while you are providing data that the solution is obvious to a standard Linux user, means you have chosen not to spend any of your life time to read Linux usage documentation.
Even if I give you the answer, you should still try to spend some of your extremely valuable time on reading technical documentation. …or hire a system administrator for your devices…
This Manjaro file path is from your system’s $ESP partition.
Find the EOS equivalent and replace the path in the command.
Use the Live USB to boot and use efibootmgr to make EOS the 1st OS to boot, using the appropriate command parameter (run man efibootmgr in a Linux terminal, for usage instructions).
It actually detected Windows no issues. The main issue I figured out later was that the motherboard moved eos grub (which contains eos and windows bootmgrs) below the windows boot manager that came with windows so it never hit eos grub.
All I had to do was change the boot order and all is well
Yes. Sometimes you have to do that. I use rEFInd also and it becomes a boot entry in UEFI so you have to change the boot order to rEFInd. This can happen with drives also depending on which drive stuff gets installed to because there is a kind of a hierarchy to the installed drives if you have multiple m.2 and ssd etc. I was just pointing out that normally grub would have the Windows entry if os-prober is installed and everything works according to how it’s supposed to work on the install.
