The Macrium PE image likely does not have Tiger Lake (Intel 11th gen mobile) drivers.
For the touchpad if you extract the following .zip and add the Tiger Lake Serial IO driver to the “drivers” folder on the Macrium Windows RE boot drive that will maybe get the touchpad working: https://www.intel.com/content/www/us/en/download/19707/30131/intel-serial-io-driver-for-11th-generation-intel-nucs.html
The boot issue I’m not sure, it would probably be easier to use F12 during startup (maybe change the timeout in the BIOS to make it easier) or boot to the device from Windows (not sure on your usecase).
