USB drive won’t boot after successful flashing.

Etcher appeared to successfully flash my usb drive with an image of Linux Mint 20 Cinnamon 64bit. I am attempting to create a dual boot of Linux Mint next to an existing Windows 10. When I enter the boot menu and select the usb drive, the light on the usb drive just flashes quickly and then nothing happens. CPU is Intel i7 9th generation. Thanks for your time!

Hi there. It sounds like etcher has done its job successfully and flashed the image to the USB drive. What is the type of machine are you trying to from?

It’s a Lenovo Thinkpad P53. Windows 10 Pro installed. Intel i7 9th gen.

One quick troubleshooting tip, is to try that Linux Mint USB drive on another computer, to see if it exhibits the same behavior. No need to proceed with actually installing it on that second machine, just test if it boots. There could also be BIOS/UEFI settings on the Thinkpad preventing booting from external media, sometimes called “Secure Boot” modes that may need to be disabled, as well. Perhaps simply try the drive on a second machine first, as a quick test.

I tried booting from usb using a different laptop (this laptop only has Linux Mint installed, no Windows). The same thing happens, but at least some text appears
on the screen:
ISOLINUX 6.04 20191223 EHDD Copyright…
Failed to load ldlinux.c32
Boot failed: press key to retry

I also attempted turning off Secure Boot and the results were the same as before.
