Hackintosh-Mini-Guides VS refind-theme-regular

You can use Ubuntu Live(without intalling it) to install reFind ! If you want to do it manually take a look here

Until recently, I had a Ryzentosh triple booting Windows 10 (primary NVMe), MacOS and Ubuntu (both on separate SSDs). I followed this guide to get rEFInd working with OpenCore.

You could also use rEFInd, see the installation guide for OpenCore

As in, setting us rEFInd? Yeah, I basically followed this: https://github.com/dortania/Hackintosh-Mini-Guides/blob/master/refind.md

https://github.com/dortania/Hackintosh-Mini-Guides/blob/master/refind.md.

You can use different bootloader like refind boot loader and chainload opencore and windows boot so they boot seperately and doesn't conflict each other . I had this same problem and I use refind bootloader. Here is guide. https://github.com/dortania/Hackintosh-Mini-Guides/blob/master/refind.md. and here is download link https://sourceforge.net/projects/refind/ you can also change themes just search on Google how to do it. This fix my issues you are facing.

My boot manager is refind (not grub), and the theme is refind-theme-regular

You can have multiple boot-loader partitions and it will detect them all without any additional setup from user. So if you are dual booting and accidentally formatted boot-loader for one operating system the other will still work. This happened lot of times for me. I accidentally deleted windows option when reinstalling linux a lot. You can also boot from usb directly from refind within needing to go into bios. You also mentioned config file for systemd being simple. Refind also has config file similar to that. And it has theming. I use this theme https://github.com/bobafetthotmail/refind-theme-regular

I actually managed to get it to work both ways: I can boot each OS in a VM from the other. A handful of scripts inside each detect the VM and make some changes appropriately (like disabling certain startup apps and services that I already have in the host OS, disabling some fancy graphics that like to glitch out in VMs, etc.). And because I like to over-complicate things, I set up static IPv4s, so I can for example connect to Linux with the same IP, not matter if it's in a VM or running on bare metal.

Also, regarding hating GRUB: take a look at rEFInd. The themes are way better [0] and it can autodetect operating systems so not only is it harder to break your system with a bad config, it'll detect USB boot devices as well so you don't have to mash F11 or whatever if you need to boot from one. It also has mouse support and (in theory) also touchscreen.

Finally I installed a simple minimal theme https://github.com/bobafetthotmail/refind-theme-regular and added the OpenCore logo to the icons folder.

I use this one.

For me, Refind it's the best bootloader for dual boot. With a theme like this it's quite pretty : https://github.com/bobafetthotmail/refind-theme-regular

I use this rEFInd theme and convert them into .icns

I would like to switch from grub to rEFInd because it has this specific theme but my main concern is: will it have an option for booting into snapshots? is a handy feature with something breaks on a update but if not that's fine!

If you want to theme refind, I suggest this beautiful theme which has distro icons for all operating systems: https://github.com/bobafetthotmail/refind-theme-regular
