I have an older laptop (HP Envy) running Windows 10. I wanted to try out Linux Mint, so I used Rufus to install the latest Mint on a new usb flash drive. I cannot get my laptop to recognize the usb and boot from it. I did notice that Secure Boot is enabled. I also went into the power options and disabled fast boot. I also know that I am using uefi boot mode. Since I use the free version of Macrium Reflect, I installed the MR boot manager. So, upon bootup, I can choose Windows 10 or Macrium Reflect. Getting into the bios settings hasn't been easy. Once I did get in, I noticed that the boot order has usb drive listed second. Any suggestions would be helpful. Thanks.
