Hi to community.
Maybe it's an old thread, but I thought it was useless to open another thread.
I just bought an Y580 on december, with win8, bluray, etc, BIOS version: 5DCN90WW (V8.01), and it doesn't recognize at all any USB device during boot. I tried to put the USB pen on every usb port, from a restart and from a shut down, but nothing. Even the boot manager with F12 doesn't recognize it.
Did Lenovo blocked the BIOS of what? Because I think it's unbelievable that I cannot boot from nothing else but the Windows Boot Manager. Or is it a problem of Win8?
Thank you guys for any help.
Here's a pic I took to show you guys that the BIOS doesn't see nothing as external.

Hello and welcome,
Try going to BIOS and tuning off Secure Boot. You may also need to set the mode to UEFI + Legacy.

This is the message I get from Windows when I try to launch the USB after the Shift + "Restart" process.
"System doesn't have any USB boot option. Please select other boot option..."
I already turned off Secure Boot....
I'm afraid that if the computer behaves like this with USB, it will do the same also with DVDs....

Actually, there is a solution that works.
When you get into the BIOS settings to the following:
1. Enable Legacy
2. Change To Legacy first
This worked for me. I was able to boot from the USB windows 10 installer.
