It was not completed, but it's fixable.

1) First things first.

Install 'screen' utility into stretch.
run 'screen' and do everything else there.
In case of any trouble (such as network connectivity loss), reestablish
your connection and run 'screen -DR'.

2) Mount chroot again (from inside the screen). Ensure you're able to
run 'apt-get update' without trouble, as you'll need it.

3) Perform the usual upgrade dance:

apt-get upgrade

apt-get dist-upgrade

The process will ask you questions (many questions, in fact), you're
assumed to choose answers wisely ;). Take special care while upgrading
grub.

4) Unmount chroot, exit screen (simple 'exit' should do it).

5) Reboot into your brand-new buster installation.
