Trying to install Arch on MSI GT75 Titan 8RG laptop with Secure Boot

I'm not a newbie when it comes to Linux, and even not new to Arch (for last couple years been using Kubuntu for its simplicity - Arch still is my true love, and Kubuntu is kind of marriage of convenience wink), but don't have any idea how to get past Secure Boot on my laptop. I have Windows 10 and Kubuntu 19.10 installed on my machine, and wanted to give Arch another try, but get this when want to boot with Arch ISO

https://i.ibb.co/5KCb6WN/20191026-201446.jpg

I know there is a wiki entry for Secure Boot, but I'm not sure how to start. Seems very complicated. Can anyone describe me how to make Arch ISO to boot when Secure Boot is ON?

Yeah, I know that "To successfully boot the installation medium you will need to disable Secure Boot.", but doing that I won't be able to access my other two OS'es.

Why can you not access them with secure boot disabled?  Why do you need need to access them during the installation of arch?
You knew the installation media does not support secure boot so the initial post was rhetorical?
Edit:
Install_from_existing_Linux you could install arch from Kubuntu but you would still have to follow the steps to enable secure boot on arch.

Re: Trying to install Arch on MSI GT75 Titan 8RG laptop with Secure Boot

So you think, that when I would install Arch with Secure Boot being disabled, and my current GRUB files would be overwritten by new installation, I still could access Windows 10 and Kubuntu, when Secure Boot will be up again?

By GRUB files do you mean grub.cfg or are you referring to executing grub-install or something else?

Re: Trying to install Arch on MSI GT75 Titan 8RG laptop with Secure Boot

Yes, as part of Arch installation process.

grub-install --target=x86_64-efi --efi-directory=esp --bootloader-id=GRUB

Re: Trying to install Arch on MSI GT75 Titan 8RG laptop with Secure Boot

What signed bootloader is the system currently using?  Do you intend to continue using that signed bootloader?
Edit:
If secure boot is enabled then boot loader must be signed if it used, the kernel must also be signed.

I use GRUB and dual-boot with Windows 10 and Kubuntu 19.10. Now I want to triple-boot.

Re: Trying to install Arch on MSI GT75 Titan 8RG laptop with Secure Boot

Easiest solution then would be disable secure boot.
With secure boot enabled you need to use a signed kernel that arch does not provide.
If you want to use the arch provided kernel then you would need to sign it with a MOK if the existing bootloader supports it or a PK.

Re: Trying to install Arch on MSI GT75 Titan 8RG laptop with Secure Boot

Disabling Secure Boot is not an option for me. I'm looking for an advice, if triple-booting is possible, when Secure Boot is enabled, and how to achieve this.

Re: Trying to install Arch on MSI GT75 Titan 8RG laptop with Secure Boot

That is covered by Secure_Boot.
I do not know if Kubuntu uses shim or preloader or a directly signed bootloader so I do not know what options that would make available.
The wiki page details all the options available to you and what steps you need to follow depending on the method you choose.
