Yoga 12 won't boot Windows 10 (often hangs at Lenovo logo)

2019-12-01, 17:23 PM

I've got a Yoga 12 that I have applied the latest bios to, and have wiped to install a fresh copy of Windows 10. I've set the bios to load best settings for the OS, and then done a restore defaults, which enables UEFI, secure boot, etc. Trying to boot off thumbdrive, the machine hangs at the Lenovo boot logo probably 90% of the time. Occasionally it will go past, but it'll fail again next time around. 

 

I've pulled the bottom of the machine and unplugged CMOS and battery for over an hour which reset CMOS. I've tried a different SSD, and I've run the lenovo diagnostics. All seem clean. Also reset the security chip, played with secure boot options (reset to factory or reset to install mode). 

 

Is there something I'm missing? Some Lenovo specific partition that needs to exist, or is the machine basically a brick at this point? 

 

I realize the machine is pretty old at this point (I believe we purchased in 2015). But it SHOULD work. I'm going to try the Lenovo recovery download tomorrow and see if that somehow functions (even though I don't want Windows 10 Home on the machine). 

 

Thanks.

Hi !

 

Welcome to Lenovo Community Forums.

 

Kindly try creating a recovery media from our support website before and observe if the machine will boot up.

same result. I got it to boot off the recovery usb, it did the initial install, then hung at the Lenovo screen when rebooting to complete.

So I believe I've found the issue. The machine will not boot reliably with a USB device attached in UEFI mode. 

 

I have to unplug the usb thumbdrive and usb ethernet, let it start to boot (spinning wheel), then plug stuff back in. It then works until it reboots again with stuff attached. 

 

This is obviously an issue... it's running latest bios. I've messed with USB settings to turn off USB3, as well as disable the always-on port. Is there some other setting I might try?
