Hi. Thanks for your article, because I almost went mad. I have a Samsung 500T tablet-pc, I was trying to complete a full format with UltimateBootCD, also tried Hirens boot, both obviously from usb (no cd unit available). And it didn't work anyway. Even with secure boot disabled. Then I tried to run Windows 10 installation from usb created with official Microsoft install tool, and also didn't work. I had to run it from Windows normally. I think the problem was the Windows 10 was loaded into an sd card with one of those USB adapters. So it was being found as generic usb card reader. I think this is a total crap from whoever it comes. If I paid for my machine I want to be able to modify it any way I want or need to. Tried every way. Shift+restart option from Windows: it shows the option to start from uefi usb. But then boots into Windows again. Found that the vol+ & vol- + power key works to get in recovery mode. Windows button (in the middle of the tablet, not the keyboard one) + power: boots into bios settings (here you disable secure boot). Pressing F10 several times gave me the typical boot menu: Here I was able to select the usb again but instead booted windows for the 10th time. So yes there is a heavy restriction not for hardware, but for software. It wasn't even able to run a Linux live usb. Any help or suggestions on how to solve or somehow bypass this will be greatly appreciated. Thanks again for this great post, as said it helped me to not waste any more time thinking I was doing something wrong. Greetings from Colombia.
