Thank you for the explanation. My MiniPC is at a not easy access location and I wish I can configure the loader to boot from the network without physically update the USB drive to run upgrades. It looks like it's not possible at this moment.

The installation was actually failed after 40%. The fdisk shows the following information. I'm not sure if the problem is on /dev/md1 that doesn't contain a valid partition table.

Is there anyway to load the loader from IPXE boot? I'm booting the loader with IPXE sanboot. It looked like the loader was trying to write sector 0xc28x to 'hd0' and failed. The Synology Assistant can still find it but installation failed at about 10%. Is there anyway to make boot loader working with IPXE boot? :synology sanboot --no-describe /iso/synoboot_ds3615xs.img || go failed goto start
