Having found my way into the BIOS to change the boot order I am faced with 4 options. Which one do I select? I want the PC to call first on a USB Recovery Drive, created with Macrium Reflect. Should I go back to BIOS to make a note of the options and list them here, as I guess they may be different for different machines?
it depends what you want to do and your system you can set the order like usb fisrt then hd then dvd if your using uefi and secure boot it may fail to boot and you may have to turn off secure boot to boot from it
Check your manual, there should be an F function key to choose first boot device, which works only once and you don't screw up normal boot order. Handy when installing OS or making changes, also when boozing with MR rescue disk.
