I've just gone a roundabout way of flashing an SD card with IoT core as my Win10 machine has no SD card reader. Using the IoT dashboard I've downloaded the image onto a USB stick and cloned it onto SD using a linux laptop (using dd with error checking disabled
dd if=usb of=sd conv=noerror,sync, otherwise it blows up a little past 8GB). However, the IoT image is resolutely read-only, I can make any changes I want, hostname (via PowerShell or the web interface), adding new files, changing the password (which then sticks for that session) but after I restart it's exactly back to stock
minwinpc. Is there something in the imaging process that ties the image to the SD card? Seems like that would prevent you restoring a device from a borked SD or is that all part of the IoT dream? None of the settings provided from the Dashboard installer are reflected in the image either?
Bad SD card - could not get it to perform any write operations, gparted,
dd if=/dev/zero and fdisk would all happily report it was blitzed only for the partitions to still be there. Very odd. I would expect flashing the card this way would in fact work, coincidence proved its undoing in this case however.
