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?

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....

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.

Same problems as yours, I have a Lenovo idealpad Y700.  Boot options used to include Windows, USB and net.  However after installing Ubuntu 16.04 and Windows getting a trojan (after hardly havin used the laptop), it was necesarry to restore Windows.  After restore the trojan was gone, but also the option to boot from USB from the bios.  Now there are two different options to start with Windows mbr (one leads me right to grub because I instructed it to do so), while the other one goes directly into Windows, after them there is an option to start Ubuntu, finally the net, I would be a bit like http://top-password.com/blog/wp-content/uploads/2014/05/lenovo-boot-mode.jpg.  But USB is gone!  How can I add it back? (Perhaps I should say I still to install another Ubuntu).
