1.1.1. Reparar la partición de arranque

  diskpart
  DISKPART> select disk 0
  DISKPART> create partition efi
  DISKPART> format [quick] fs=fat32
  DISKPART> assign letter=B:
  DISKPART> exit
  bcdboot C:\Windows /s B: /f [ALL|UEFI|BIOS]

  1. Enter live mode
  2. Unmount all partitions on media with umount /media/*
  3. Make a ext4 partition named SB@ with label also SB@. Set the boot flag of that partition with GParted,
  for example.
  4. Recreate the structure of the disk using hard links with a device name that systemback recognizes,
  as /dev/sdd. I have /dev/nvme0n1 as the actual disk and 7 partitions nvme0n1p1, nvme0n1p2, ...
  so the commands are:
  ln /dev/nvme0n1 /dev/sdd; for((i=1;i<=7;i++)) do ln /dev/nvme0n1p$i /dev/sdd$i; done
  5. Then run systemback. You should be able to select the new ext4 partition to install the system.
  Step 3 may not be needed, but Systemback didn't see the free space on the disk so I made the SB@ partition

1.4. Windows messing with bootloaders

No bootable device found
Windows overrides the nvram
Live usb, mount your ssd, chroot to that folder, use refind-install (arch package)
