This problem is resolved, thanks. But I still can't reconfigure system (‘--verbosity=10’ needed to see some output, otherwise absolutely nothing in console). Experimentally, I found out that the problem with the following code blocks: 1. in file-systems: ;; (file-system ;; (device "c36b9de3-2b00-4263-8844-9f2d72628d78") ;; (mount-point "/mnt/oldhome") ;; (type "ext4") ;; (options "noatime,discard 0 0") ;; (title 'uuid)) 2. and in bootloader configuration: (bootloader (bootloader-configuration (bootloader grub-bootloader) (target "/dev/sdd") ;; (menu-entries (menu-entry ;; (label "OldLinux") ;; (linux "/boot/vmlinuz-4.14.9-calculate") ;; (linux-arguments '("root=/dev/sda3")) ;; (initrd "/boot/initramfs-4.14.9-calculate.img"))) )) If to comment out them (as above), then process starts, otherwise the output is visible only with ‘--verbosity=10’ and nothing else happens, there are no errors. But I need a possibility of the login in old system and old partitions are necessary :)
