Ok my daughters Acer laptop already has Windows 8.1 installed. It has a MBR disk. My USB Flash Drive won't boot from it but it does my my desktop so not the USB flash drive.The flash drive was created for UEFI or MBR boot using Rufus. I tried the tutorial in sevenforums to convert the Acer to GPT but it says the boot drive is in use and can't. I tried to boot to a Command Prompt but that gives me an X: drive and I can't change it to C prompt. I have done this before from a boot drive and it worked but won't on this machine. How can I get this converted from MBR to GPT??? How can they make that tutorial work for them? They are doing it from within windows there??? This machine BIOS has nothing for legacy or UEFI or secure boot for sure. Is my only option MBR then? If it is what do I make the flash drive with as Rufus option says for UEFI or MBR but won't boot this machine. Yes I have it to boot first but it lights up but goes straight to windows. Thanks for any insight here.
