Historically, Lenovo cripples its BIOS.

Re: No USB boot option?

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.

Thanks for the quick reply.

Boot Mode just has UEFI or Legacy Support, but no UEFI + Legacy. Is it normal?

Re: No USB boot option?

This is the message I get from Windows when I try to launch the USB after the Shift + "Restart" process.

http://s14.postimage.org/a3xjrimpd/IMG_1881.jpg

"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....

Re: No USB boot option?

After putting Legacy Support (leaving UEFI first) now it seems it can read the USB pen on boot.

Now everything seems to be working.

Thanks.

Re: No USB boot option?

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.
