Posted: Sat Apr 14, 2018 6:48 pm Post subject: Dual Boot Arch Linux/Gentoo |
|
|
Before i eventually mess things up, i don't really get it. I have installed Gentoo at least 20 times over the years and Arch Linux probably more than that but when it comes to dual boot i dont really understand how to accomplish the task as smooth as possible.
My current setup is Arch Linux EFI and GPT systemd all over the place, systemd-boot, networkd and so on, works like charm.
I'd love to install Gentoo Linux on the same computer, but this time as dual boot, with an entry for Gentoo in my bootloader (systemd) but i do not want Gentoo on systemd but OpenRC and i don't want Arch Linux to use GRUB.
I have a bunch of Nvme- and SSD's in the computer, so i can dedicate one drive completely for Gentoo. But is it even possible?
I know i can install GRUB2 on that dedicated drive and use F8 to choose which OS to start, but can i mix systemd-boot to get an entry for Gentoo in it?
E: MBR/legacy is not an option. I don't even know how to install Linux without EFI. |

Can you not just choose the boot disk in the uefi/bios menu of the motherboard?
edit: Doh, sorry, you already covered that. |

Actually, i think that's the smoothest solution. No biggie. |

Adding boot entries to systemd-boot seems to have a more relaxed syntax than grub2. I would give it a try as it's already there. |

True, thanks, then maybe i don't need Grub at all. |

It looks like it will look in the ESP for a kernel/EFI stub to boot so you probably need an EFI stub kernel and not worry about a built in command line as systemd-boot config has an option for "options" for kernel command-line parameters. |

Other options include using the EFI boot loader. You may be able to configure it to act as a conventional boat loader then chain load systemd-boot or how ever you want to boot gentoo.
Another option is rEFInd. It can be used to chain load or boot directly and can be an elegant solution. _________________ First things first, but not necessarily in that order.
Apologies if I take a while to respond. I'm currently working on the dematerialization circuit for my blue box. |
