   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?

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:
