The pre-activated Win10 was working fine on the eMMC. I wanted to install Proxmox instead on the eMMC.
Booted from flash drive and started the install to /dev/mmcblk0 (58GB). There are 2 other 4MB partitions as well, I assume from the Win10 install. The installation fails with “unable to get device for partition 1 on device /dev/mmcblk0”
Now the eMMC does not show up in the BIOS.
Any ideas on how to install or get the eMMC back?
