I'm having trouble locating information on installing linux on a ASUS laptop with Windows 8 pre-installed. I'd like to (1) retain the existing Windows 8 partition since its loaded and configured to my tastes; and (2) retain Windows Secure Boot.

It appears ASUS has not released any information on the configuration or steps to perform the Linux install. https://www.google.com/search?q=asus+dual+boot+windows+8.

SuperUser has some similar questions, but some questions don't have answers and most (all?) questions don't have anything concrete on steps to perform.

Does anyone know of an official ASUS document or KB covering a Linux/Windows 8 dual boot installation?

  • I can help you with partition and boot, not with keys. As for the whining, I believe they are complaining because the certificates are provided by MS. – MariusMatutiae Dec 9 '13 at 11:27

You are seeing this from the wrong perspective. There are tons of (answered) queries on Windows/Linux dual boot pcs, on this site and others like this one.

There is nothing instead (or very little anyway) on a dual boot retaining SecureBoot, because this is still either not supported by most Linux distros, or only partially supported by some of them.

This useful blog post states, among many other things:

Choose a Linux Distribution That Supports Secure Boot:

Modern versions of Ubuntu — starting with Ubuntu 12.04.2 LTS and 12.10 — will boot and install normally on most PCs with Secure Boot enabled. This is because Ubuntu’s first-stage EFI boot loader is signed by Microsoft. However, a Ubuntu developer notes that Ubuntu’s boot loader isn’t signed with a key that’s required by Microsoft’s certification process, but simply a key Microsoft says is “recommended.” This means that Ubuntu may not boot on all UEFI PCs. Users may have to disable Secure Boot to to use Ubuntu on some PCs.

I am afraid you may have to experiment a bit yourself, and that the outcome will depend on both your pc and the distro you intend to install, i.e., that no general recommendations can be made.

  • Thanks MariusMatutiae. I've been through the UEFI Security area. I know I can add additional Platform Keys (PKs) and other security bits such as signatures to the DB. I'm not sure what the Ubuntu or Fedora folks are whining about because I can add their signing keys (if they provide them). Now I need instructions on doing it for the laptop. What I'm not sure about is the precise steps to load the keys, create the partition, and create the boot options. I need this from ASUS or Phoenix (who makes the UEFI). – jww Dec 9 '13 at 11:21

    @noloader - Your unlikely going to presuade either party to provide you those keys. The best suggestion at this point disable secure boot if you want have a dual boot. There are several approaches that one can take to leave secure boot enabled and dual boot but not every approach is supported by every OEM. In order to be sold as a Windows 8 device, secure boot MUST have an option to be disabled, unless its an ARM device. – Ramhound Dec 9 '13 at 12:30
  • Thanks Ramhoud. "Your unlikely going to presuade either party to provide you those keys." - they are public keys. Why would they be held so closely? – jww Dec 15 '13 at 14:19
