Sometimes the PC doe not present us with the F1, F2 or F12 options. If you cannot access the options to jump to BIOS during restart, you could try a few options which i have found helpful. Please help, I've been working in a Mac shop for 4 years and I think I'm missing something about this new-fangled UEFI and Windows 10! Also, Lenovo support sucks and I've given up on them, well not entirely, I'm sorta racing them against the Spiceworks community and I think they'll lose!įrom what you've said, I can tell you for sure that Your USB Flash drive is okay, it can boot etc.Your BIOS or UEFI settings are the problem. After I got to the recovery settings and go to the option to change UEFI settings and hit reboot, it sends me to the black screen (basically never makes it to Phase 2 of those instructions). I tried Lenovo's general accessing UEFI/BIOS instructions, but they just led me back to black monitor and glowing power button.

It of course boots fine to the factory Windows 10 install.

It also refuses to boot if I hit F1 or F12 as I power it up. When I plug in the flash drive (tested good on a Windows 7 PC) it won't boot, as it doesn't even activate the monitor I suspect it's an issue with UEFI and secure boot. I am helping a friend setup a new Lenovo IdeaCenter (510A-15IKL 90GV000CUS) and I'm having issues getting it to boot from a flash drive.
