No answer about "platform reset" maybe I simply do not remember but - I have installed Linux Mint / Mate (including Trinity) on two Asus Zenbooks without a problem. The last was a Zenbook Flip of a friend. My Bios tells me: Platform Mode User Secure Boot Disabled Secure Boot Control [Disabled] On my Laptop I can reboot into original Windows 10. sudo fdisk -l gives me Device Start End Sectors Size Type /dev/sda1 2048 534527 532480 260M EFI System /dev/sda2 534528 567295 32768 16M Microsoft reserved /dev/sda3 567296 117864447 117297152 56G Microsoft basic data /dev/sda4 117864448 485423041 367558594 175.3G Linux filesystem /dev/sda5 499095552 500117503 1021952 499M Windows recovery env. /dev/sda6 485423104 499095551 13672448 6.5G Linux swap Partition table entries are not in disk order. On her Laptop I moved the original installed Windows into a VirtualBox image according to https://www.gaulnet.de/physical-to-virtual-p2v-windows-pc-in-virtualbox-kopieren.html and https://www.tenforums.com/tutorials/2206-hyper-v-create-use-vhd-windows-10-disk2vhd.html formatteded the disk, installed Linux and installed Windows inside VB. All works well. No access to her Laptop at the moment. Hope that helps Gerhard
