Nope. works fine, had already used it. You need to flash the iso created by Reflect with Rufus, select GPT and FAT32 (important, not ntfs). Then you shutdown the tablet. power it on, esc => bios/uefi. then go into the last tab, boot override. select stick. done.
@Hans: Thanks for your help. I did as you advised, but the stick did not show up in the bios. I attached it via the OTG cable from Cube on the tablets USB 2.0 port. Did I make any mistake though?
Mostly. If you did not do what I said then it wont show up. Needs to be GPT AND fat32., and I hope you wrote the ISO to the stick… also you need to boot it from shutdown state with connected, otherwise bios will bug and wont show it.
