Okay. I have a laptop here with windows, haiku and Linux. And actually the grub (2) configuration to get haiku to start was strange. What exactly do I install best to replace grub? Or alternatively, I have a PC with only Void Linux. Compatibility mode for booting, since uefi mode did not work (I dont know why - some secure boot shenanigans? MBR vs GPT mode? There is no EFI partition as well). What could replace grub there?

I am on Void Linux too, and grub works fine. sighs. Why would I replace what has worked for decades?

  I personally would like to be able to enable the UEFI boot mode of the board, so that I can enable Resizeable bar - for the performance benefit and to have the option to add an Intel GPU later. So cleaning up the GRUB situation could help me there - that's why my comment above was completely serious, I'd really look at suggestion. Because otherwise I see it like you, why change what works. Even the move to Grub 2 with the more complicated config options wasn't all that bad, since it really needed less often to be configured manually. So after a bit I was fine with that.

In same boat here. I just do not understand the *EFI stuff anymore, and I've tried. I somehow got refind to work, after disabling some vaguely named "secure boot" option in the BIOS. It shows my several linux options, and the only one that works is "rescue", that boots what is apparently a systemd bootloader with Nix generations. When I select Windows, I get some windows boot menu/loader instead of directly booting Windows. I have no clue how it all works - there is some partition with some files, but I also must run some command to "apply" changes - I think. It's horrible.

I don't know if it will work for booting Windows, but have you tried installing Haiku's BootManager to the MBR? https://www.haiku-os.org/docs/userguide/en/applications/bootmanager.html https://www.haiku-os.org/docs/userguide/en/applications/boot... On the booting Windows front, this thread has a few people describing how they successfully used BootManager to dual and triple boot Haiku, Windows 7, and/or Linux: https://discuss.haiku-os.org/t/dual-booting-haiku-and-windows-7/1690/13 https://discuss.haiku-os.org/t/dual-booting-haiku-and-window... I have a laptop (Lenovo ThinkPad T410s) with Haiku, Linux Mint, and Devuan GNU/Linux. I use BootManager in the MBR, and it gives me a menu of all three to choose from. For the two Linux options, I have GRUB installed on each of their own partitions, so BootManager just sends me to the GRUB installed on whichever Linux partition. (Of course, this isn't exactly "replacing" GRUB altogether.) I do it this way because I find dealing with BootManager to send me to individual GRUBs to boot a particular Linux partition much, much easier than fiddling with GRUB to boot Haiku. (One last thought, parenthetical as I'm not sure it can even work from a USB drive: Worst case, you might make a USB "boot stick" that uses BootManager to choose between Haiku and Linux and let Windows do its jolly thing on the MBR?)

  I tried to install the BootManager, but the limitations mentioned in the docs blocked the install. I think this part: > BootManager isn't yet tested very well and still has a few restrictions that it will complain about if they aren't met: the menu can only be installed on your first harddisk and there has to be a 2KiB space after the Master Boot Record (MBR). No idea how to create those conditions, the 2KiB space, and since I would have to do it with gparted in Linux anyway this made me install Linux instead first (with grub). BootManager actually sounded nice - like you describe, I expected it to simply offer me the other OS(s) option(s), and I wasn't even set on installing Linux in the first place on that machine. To your parenthesis: Yeah, I even had a boot manager on USB once for my PC, so it crossed my mind here, but for a travel laptop this would be a bit uncomfortable.
