How to run 10ku from a flash drive?

Question

Windows

Hello, I need help because I don't know what to do.
The bottom line is, I can’t run the installer from this Lenovo v580 laptop model, I scrolled through 2 forums, and 3 manuals, without results, I even “go into” the BIOS through the battery.
main
bios version. 1.12
Startup
Network Boot USB HDD
UEFI/Legacy Boot Both
UEFI/Legacy Boot Priority Legacy First
But does not see the flash drive

The issue was resolved in other ways. Thank you all for your advice and sorry for the hassle!

Answer 1

Flash drive format is not suitable for UEFI, make a flash drive with Rufus
