Well, funny. This is not hard at all. Just keep pressing esc key while booting up your machine. You will see a Window with select boot device option like the above image. Importantly, you can see that your one bootable USB device shows two options: One is "USB Flash Drive 8.00" The another is "UEFI: USB Flash Drive 8.00..." Select the first option if your system is in Legacy BIOS mode with MBR partition. This scenario is common with dual boot systems that has Windows 10 installed. If you examine your hard disk partitions using whatever partition manager you use, you probably will find a "System Reser...
