Dual Boot GuixSd along side other preexisting distros

Dual Boot GuixSd along side other preexisting distros

 Hi Guys,
Can you guys please help me with a bit of understanding?

I have a ThinkPad T410 on which I am trying to do this. Currently I have a dual boot configuration running Ubuntu and Windows 7. Could that grub install failure because of my /boot not being empty and formatted afresh for GuixSD? If so, can anyone of you please help me in figuring out how to install GuixSD alongside those existing ones(other distros plus special Mr. Windows)? Do I need to reformat my /boot to make it fresh so that Grub install from GuixSD installation could succeed(not sure if this is the reason for failure).  if a reformatting is imminent, what will you suggest to do on case I just need to recover my old stuff?

Thanks and Regards
Nalin Ranjan

I can share my solution. I am running dual boot with openSUSE and
GuixSD. GRUB is managed by openSUSE and it sourcing GuixSD
configuration from /boot on GuixSD partition. That brings Guix menu
entries to the GRUB.

In my system configuration I have this hack I found somewhere:

 (bootloader
  (bootloader-configuration
   (bootloader
    (bootloader
     (inherit grub-bootloader) (installer #~(const #t))))))

so it doesn't install bootloader at all.

My usecase is a bit special because I am using LUKS and unlock it on
bootloader level.

If you want your bootloader to be managed by GuixSD, just follow
corresponding part of Guix manual:

  https://www.gnu.org/software/guix/manual/en/html_node/Bootloader-Configuration.html

I had a dual boot set up for a while, but I let guixSD take care of the
grub generation.  With guix you can configure the bootloader to boot two
different OSs.

I don't think we can boot non-linux systems. If I'm wrong, I'd be very 
happy to know how.
Right now, I have to use the grub command-line and run "chainloader +1" 
to get in my
haiku system :/

FYI, the --no-bootloader option to "guix system" should prevent Guix
from installing a bootloader.  You might find that useful.

I personally found it more useful to have GuixSD manage my grub.  And
code in my config the other boot option.  That way GuixSD generated the
grub booting for both GuixSD and the other distro.
