When I dual boot Linux and Windows, I like to have two separate drives and not ever mix up the bootloaders. I then use my motherboards boot selector to choose which one, and I leave the main OS as the first priority one.

Works perfectly, avoids Windows overwriting Linux and avoids GRUB breaking for the 11th time this month because it's a terrible piece of software. The only downside is it takes 10 seconds longer, because whenever I want to change I need to wait for my motherboard to recognize the boot selection key.

Most distros will run the grab is prober and add the additional entries.

This reminds me of my first week running Mac OS and searching increasingly frantically for an uninstall script for an application I'd installed.

Oh.

Drag to trash. Really? OK.

If you have a choice - use Onshape. Fully featured CAD system, on par with SolidWorks and such, works perfectly on Linux out of the box.

My condolences

I want to like nixos but the documentation is trash.

Assuming that you are dualbooting from a single storage device - If you have some money to spare go and buy a second ssd. Keeping both OSes in separate storage devices will result in far lesser chances of screwing up.

I always get a Clonezilla image made before I do any major changes, which I find takes the anxiety out of situations like this.

systemd-boot discovers windows automatically, no need for configuration.

Why not installing windows in a vm?

Man, I want to dual boot, but I'm scared shitless. I don't want windows to fuck my 1.5 years work on my current set up. VM for now until I find a solid and "complete moron" proof tutorial to go forward.

two little tips:

you can backup your EFI partitions, in case you mess them up. I find it a good idea to back them up in any case, I have had EFI partitions get Filesystem corruption.

also the tool rEFInd can work as an alternative boot menu it has the ability to scan the entire system and show all found Bootable OS at boot time.

So with rEFInd, you install it, set it as the default, and it should show windows automatically.

it looks nicer than systemd-boot and grub as well. And it can even show bootable USB flash drives, and has a few other features.

FreeCAD is a lot more okay than people give it credit for. Perhaps I just remember back to the early days when it was basically unusable.

Yeah, I was about to say when I read the first part. Adding windows manually is quite an old thing. Modern linux setups with grub2 will "find" the EFI loader for windows and add it automatically.

I lost my grub loader when I upgraded hardware recently. But, I just booted into a linux USB, chroot (remembering to mount /boot/efi) and re-run grub install/grub update. That didn't find windows. But, it was fine because I just properly booted into linux and ran grub-update again there, and it found it fine.

Yeah this isn't really much of an issue with EFI now. You can change boot order in the BIOS and things are way less likely to get overwritten or broken. You can even have 2 EFI partitions if it's something your concerned about.
