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

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

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.

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,
