[-- Attachment #1.1.1: Type: text/plain, Size: 670 bytes --]

I have tried to install GuixSD on my non-UEFI PC from USB and I have
encountered multiple problems.

1) The USB is /dev/sda while HDD is /dev/sdb during the installation,
but after reboot HDD becomes /dev/sda.
How do I set the device for the bootloader and swap partition without
using device tree name (/dev/sdX)?

2) I have set the labels on HDD partitions this way:
/dev/sdb1 (ext4) - boot
/dev/sdb2 (ext4) - root
/dev/sdb3 (swap) - swap
/dev/sdb4 (ext4) - home

The config file for my system is attached.

After invoking `guix system init /mnt/etc/config.scm /mnt` and rebooting
the OS fails to mount the partitions because it doesn't detect them.

That's strange, as this is working for me on guixSD 0.11.0 installed in a Qemu
VM.

Hi, and sorry for the late reply!

dt <dtluna@openmailbox.org> skribis:

Use a device label, as suggested at:

  https://www.gnu.org/software/guix/manual/html_node/Preparing-for-Installation.html#Disk-Partitioning

The config file you posted does use partition labels, as in:

  (file-system
    (title 'label)
    (device "root")
    …)

Could it be that the partitions actually carry a different label?  You
can check that by running ‘e2label /dev/sdX’.

HTH!

Ludo’.
