Ideapad Y400 Cannot boot from USB

I have ideapad y400 and am trying to dualboot windows8 and linux.  When I press the bios button on the side of computer, the computer cannot find the usb in the boot menu or the bios.  I am positive the USB is bootable because it works on my old laptop.  There is no option to boot from USB.  In bios, USB Boot is yes (by default).  I can only boot from windows boot manager and ipv4 and ipv6.  No usb.


I read that the USB may not work with lenovo, but I have tried two USB sticks: Sandick and Verbatim.  


I also read that I may need new bios software, but I doubt that because I just got the laptop, and I could not find windows 8 bios update under the y400 drivers.


Thank you.

Hello and welcome,


Try going to BIOS, turning off secure boot, selecting legacy boot or UEFI + legacy.

Re: Ideapad Y400 Cannot boot from USB

This worked for me just now. I have a y400 and was trying to boot from a recovery disk. The only way to get the optical drive to display was to turn of secure boot, select legacy boot and then legacy first. Thanks.
