So I'm a recent Linux user (as I created a duelbooting system this week for the first time) and I did as you said in this comment and downloaded rEFInd. Is that all you have to do or is there more to the part "manually create boot files for each"? If so would you mind giving me a brief rundown on how to do the same?
I installed Windows and Linux via command line from their installers. I did Windows first, then Linux. Each OS has its own SSD (This is where I manually created boot files for each). I booted into Windows to complete the install then did the same for Linux. Once that was done, while still in Linux, I created an EFI partition on a shared data drive. I placed refind on that and configured it. With all of that complete, I boot into firmware settings and set refind as the default.
For this to work without issue, you need at least two drives. I have three to make it even easier.
If Windows and Linux share the same drive, set up a manual partition layout with two EFI partitions. You'll end up with this:
EFI || EFI || WinRe || Windows || LinuxThe first EFI partition is for Windows, and the second is for Linux. Complete the OS installs and use a second drive for a third EFI partition to set up refind. Again, configuring it and then setting it as the default.
Thank you for the reply. This won't work for me because I'm stuck duelbooting from a single SSD on a laptop. But maybe it can help someone else that stumbles on it.
I've not tried it, but you can do three EFI partitions on the same drive. There's no real limit to how many EFI partitions you can have. The key here is to keep Windows and Linux boot files separate at all times. If they share the same EFI, then Windows will undoubtedly break it at some point. Having refind as the default just makes it easier to choose which OS you want. Rather than relying on Windows Boot Manager or Grub. Of course to do all this you need to wipe the disk to set up the layout.
