I've used it many times now and it works under all boot conditions, UEFI/GPT/MBR or CSM/MBR.ġ.
Here is a manual (non-Rufus) procedure originally posted by NavyLCDR that I recorded and saved (with slight modifications). The weird thing is i can Install Steam OS Beta or Ubuntu no problem with UEFI, just not windows, when i try to boot it with legacy support enabled and make the drive with Legacy (MBR) in RUFUS it loads to a blue screen and gives me a ACPI error I Don't know if the UEFI is corrupt i have reset the BIOS and factory Reset the bios with the button keys that dell support website show still no luck i cant install windows 10 at all which is what the device originally came with but i bought it second hand for like 100$ but would like to get it working I Have a Dell Inspiron 15 Gaming 7567, when ever i create a UEFI bootable USB recover whether it be With RUFUS, Windows Media Creation Tool or even with the Dell OS Recovery Tool Program it will only boot the USB (i can see the activity light on the Flash drive flashing rapidly) then Show the Dell Logo and then before the Spinning Circle of Dots loads or the windows setup it restarts and just keeps doing the same thing over and over again.
