Hello Tzafrir,

The twist is that I need to boot some kernel to run it.
What I did was:
1. Leave both disks connected to the PC.
2. Boot from the old (500GB) disk.
3. Mount the partitions of the new (2TB) disk on a directory tree
originating in /tmp/new_2T, so that the to-be-root partition is mounted
on it and other partitions are mounted on subdirectories of the
to-be-root.
4. chroot /tmp/new_2T/ update-initramfs -u -k all -v
5. Reboot - this time into the new (2TB) disk.
6. Get stuck because it doesn't find the root and swap partitions.

How did you boot your PC to run update-initramfs?
