the /cinch/tmp/found_hw error is because cinch didn't find any supported hardware. When you booted, was your network configured? Was there any network support in cinch?
Here is one of mine from another box:
title cAos: Community Linux 2.0 (220.127.116.11-18.caos)
kernel /vmlinuz-18.104.22.168-18.caos root=/dev/hda2
You will probably need to edit the root line to suite your needs, and you will also probably need to tell grub where the boot partition is with something like:
but remember that you must edit that line to suite your needs. The first 0 represents the disk number -1, and the second 0 represents the partition number where /boot can be found -1.
