Hello, Gentooers,

I just acquired a new Asus board (b560m tuf gaming+wifi) to replace a
failed gigabyte board on my main Gentoo machine.  Assembly went well, it
powered up flawlessly first time, it recognized all the hardware... and
then nothing.   Cannot get it to boot.

On all my other machines, there’s a bios setting that allows me to turn off
secure boot, which allows me to boot Sysrescue from usb, or Gentoo from a
hard drive.

Not so (as far as I can tell) on this mobo/bios.  There’s the usual bios
boot menu and a secure boot submenu.  However, the secure boot submenu only
allows me to select between Windows UEFI (with, presumably, secure boot
enabled) and “other OS”.  I have no clue what “other OS” implies about
secure boot.  It also offers the ability to accept the standard
Microsoft-supplied secure boot keys, or to change or delete them.  There
are a few claims on the web that clearing the PK key (and only that key) or
clearing all of the keys is the way to turn off secure boot.   I’ve tried
all the combinations; none of them allow me to boot.

The farthest I’ve gotten is to display the Sysrescue usb boot choices.
Selecting any of them seems to (briefly, for a second) start a boot and
then the screen goes blank.  Nothing after that.

I haven’t found any mention on the web that Asus boards are particularly
linux hostile, nor much discussion implying that turning off secure boot is
particularly tricky.  Most of what I’ve seen is, say, Ubuntu oriented.  I
gather that they have gone through the process of getting their secure boot
keys authorized by Microsoft.

Anybody have success getting Gentoo to boot from a recent Asus mobo?

Thanks!

John Blinka

I have an Asus TUF Gaming X570 and have the secure boot OS type as "Other
OS". I've been using rEFInd to dual boot with Windows.

So, this suggests that “Other OS” was sufficient to allow you to boot some
kind of Linux distro, which you then used to install Gentoo.  I take that
as proof of concept that what I’ve tried *ought* to work.

Thanks for that reassurance!

Thanks for the suggestions for solving my booting problem, which admittedly
is not particularly Gentoo related at this stage in the installation
process.

I’ve tried usb sticks with both Sysrescue and Ubuntu server to boot this
thing.  It appears to attempt to boot each one, but then the screen goes
blank after 1-2 seconds, at which point I can’t tell what’s going on.  Each
usb stick boots my other machines normally, and the screen works normally
when used as a display for my other Gentoo machines.

Your suggestions imply that there’s nothing especially magical about
putting Linux on Asus mobos and that I’m setting up the bios correctly.  So
I’m coming to the conclusion that this mobo may not be working as
intended.  Back it goes!

I think I had used the Gentoo live USB originally, although I've the
gparted live USB as well. Sysrescue ought to work but I'm wondering if
there's an issue with a missing GPU driver or something. Granted, id be
surprised that both sysrescue and the Ubuntu server USBs are missing
drivers.

What is your graphics setup? Integrated? Dedicated?

I suspect the OP has seen these but I'll post them anyway in case they
haven't popped up yet:

https://wiki.gentoo.org/wiki/User:Sakaki/Sakaki%27s_EFI_Install_Guide/Creating_and_Booting_the_Minimal-Install_Image_on_USB#turn_off_secure_boot

https://wiki.gentoo.org/wiki/User:Sakaki/Sakaki%27s_EFI_Install_Guide/Configuring_Secure_Boot

I'm at the point where I'm looking at building a new machine and being a
long-time Asus user I'm pained seeing the pain being inflicted.

This could possibly be KMS kicking in, try adding nomodeset to the boot
options. While you're editing the boot options, you may as well remove
any quiet or splash options too, so you can better see what is going on.

So what I guess *might* be happening is that there is a signed
boot-loader on the "other OS" on CD, but because the gentoo boot loader
is not signed, that's why it's not working ...

So somehow you need to get your "other linux" booted again, get back
into gentoo, and install a signed binary boot loader. Pain in the Arse!!!

Wol

I suspected that sysrescue and Gentoo do not have signed boot loaders on
their isos (does Gentoo even have isos? Haven’t used anything but sysrescue
in ages…).  That’s why I downloaded and tried the current Ubuntu server
iso, believing that it would have a signed boot loader.  That didn’t boot.

KMS… had to Google that. Not that I am fluent in this stuff
(understatement!) but how does one add nomodeset to boot options, or edit
boot options?  The world I’m living in consists of downloading a bootable
Linux iso image,  dd’ing it to a usb stick, then trying to boot my
recalcitrant Asus board from that.  What you’re suggesting sounds to me
like rolling my own Gentoo usb boot stick.  Is
https://wiki.gentoo.org/wiki/Install_Gentoo_on_a_bootable_USB_stick is the
place to go for that?

Press e at the boot menu, that's the usual key to edit the boot options.
You may have to press a key, usually space, to bring up the boot menu,
depending on the ISO you are using.

I'd be surprised to find that "Other OS" is a secure boot option, it
sounds like the option to run without secure boot.

  The default ISO USB action is to wait a few seconds and then boot the
standard kernel.  Tap "any key" (e.g. spacebar) ***BEFORE THE WAIT TIMES
OUT*** and then type in the line...

gentoo nomodeset

...followed by the {ENTER} key.  That should boot with the nomodeset
option.

Cool!  I’ve been linuxing for decades and never had the need to do this.
Until now.  Sysrescue booted (has probably been booting all along) *and*
with nomodeset applied I can now see what it’s doing on the monitor.  Now
that I’m on terra firma, hope it will be clear sailing from here.
 (Apologies for the clash of metaphors!).

Perhaps.  That will be one of my experiments once I get things working.

Thanks - works like a charm! (And I learned something new.)

And it appears your intuition is correct.  I left all the “secure boot”
options in the bios at their defaults except one.  I changed “OS Type” from
“Windows UEFI mode” to “Other OS”.  That was sufficient to boot from my
Sysrescue usb.

  I should add...

1) you can enter multiple parameters on the commandline, separated by a
space.  For an incomplete list of boot parameters, scroll through...
https://www.kernel.org/doc/html/v4.14/admin-guide/kernel-parameters.html

2) these instructions work for a LILO boot.  On a GRUB boot system, if
you want to add one-time kernel boot parameter(s), see...
https://wiki.ubuntu.com/Kernel/KernelBootParameters for instructions.

One other little point of interest ... so does that mean 
non-windows-uefi, or does it mean bios legacy?

That could be important information at some point, especially if you 
want to dual-boot.

I boot with UEFI using that setting so i assume it means non-Windows-UEFI,
weird.
I've been booting Windows and Gentoo without issue so Other OS should be
fine for that.

Don’t know for sure.  Suspect it’s non-windows-uefi.  There’s a separate
option in the bios boot submenu called CSM (Compatibility Support Module).
Googling this suggests to me that this is the bios legacy switch.  I’ve
moved on to uefi exclusively, am beginning to get a grip on it, and will
not dual boot on this box.
