Hello! I was not able to install Guix having 2 partitions:
/dev/sda1 ext4 Linux filesystem
/dev/sda2 Linux Swap

`guix system init` says in this case:
guix system: error: failed to install bootloader

Hi,

which grub is that? grub-efi?

Installing GRUB to your root partition isn't supported, and should 
never be necessary anyway.

This is a strange partition layout; it's missing a ‘BIOS boot 
partition’ and can never work without forcing GRUB to do something 
it doesn't like to do.

Did you create this layout manually?  If so, why?

Kind regards,

i386-pc, so ‘BIOS’ (which means it's trying to use blocklists, 
which is fragile & won't work without --force).

I have another laptop (Lenovo G50-30) where Guix works on this partition layout I've made manually:

# fdisk -l /dev/sda
...
Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1            2048 230000000 229997953 109.7G 83 Linux
/dev/sda2       230000640 234441647   4441008   2.1G 82 Linux swap / Solaris


But all the new installations on other two notebooks with the same layout do not work.

Yes, I use Bios grub everywhere.

FWIW, I used this partition layout for years, including on Guix systems,
and it worked fine.  Long ago, bootloaders were only able to access the
first 8 GB or so of the disk, because of limitations in the old INT 13h
BIOS interface.  Maybe this is still an issue on some ancient machines,
but I tend to use older hardware (my best laptop is ~11 years old, and
that's typical for me) and I've not had this issue in recent memory.

The only reason I started using a separate boot partition again is
because I now encrypt my root partition.

^ You removed the most important part, please don't do this on 
help lists.

Still, we can tell that this is an ‘mbr’ layout:

                                                       ^^^^^^^^^^^^^^^^^^^^^^^

They aren't the same: the one in your screenshot is a completely 
different ‘gpt’ layout.

Hence my unanswered question:

> Did you create this layout manually? If so, why?

Although now I suspect there was no reason and that the installer 
isn't to blame.

So you can either:

- throw away your existing layout and create new MBR disklabel. 
  Your partitioning software will ask you or provide an option 
  somewhere.  Since modern partitioning software leaves a huge gap 
  before the first partition, GRUB will nestle cosily into that 
  first unused ~MiB.

- keep it as GPT (it has some minor features MBR doesn't), and 
  create an additional GPT ‘BIOS boot partition’ as recommended 
  before.  It only needs to be a few 100 KiB, so I use the space 
  before the first partition (= before the first megabyte; turning 
  off ‘alignment’ in your partitioning software).  This tiny 
  partition is for use by GRUB, and GRUB alone: do not format or 
  mount it.

Both options work equally well, but you need to choose.

Kind regards,

T G-R

The graphical installer does not display a warning when not adding a
separate boot partition on GPT (an installer bug?), but installs
everything only to fail at the very end (this is another bug of guix
system?) at bootloader installation.

In fact, it _is_ possible, if you use an MBR partition table.  I assumed
that znavko was using MBR, but having now finally looked at the provided
screen image, I see now that they're using GPT.  I agree that in this
case, a BIOS boot partition is required.  I should have looked more
closely before responding, sorry.

     Best,
      Mark
