Lenovo Yoga 920 Boot Device Missing

2019-04-01, 4:39 AM

Hi, I can't seem to boot my Lenovo Yoga 920. I've searched online about BIOS but don't have the option to change from UEFI to Legacy in BIOS Setup > Boot Setup. Also, my hard disk is not being detected. Does anyone have a fix for this?

Hi gsu,

 

Welcome to the Community Forums.

 

Similar to this discussion, Kabylake CPU intended not to use CSM features to support Win10 UEFI. I checked with the latest BIOS but do not include any changes of enabling Legacy option too.

 

To this effect, you may first check if your harddrive is visible/ readable on other machine to rule out HDD failure.

 

If it does shows up perhaps you can take time to back up your files and have it reformatted to FAT32 instead of NTFS. Restore it back to the machine and see if the BIOS sees it under the information tab as done here.

 

I hope this helps answer your query.

Update us how it goes.

 

Regards

Ugh, this just happened to me, now I'm running around the Lenovo Forums trying to solve it as well.

 

Did you guys find a resolution?

Did you ever find your solution? Have had this happen to me 5 times in the past month and it just randomly fixes itself after a few days.

Anyone find the resolution to this problem? Seriously ridiculous that I can't even use my laptop that I paid $1200 for.

I'm also having the same problem with my Yoga 920.

 

Default Boot Device Missing or Boot Failed...

 

and No UEFI to Legacy option in the BIOS either.

 

I had this happen where it would never boot back up without this error back in September 2019 and sent it to Lenovo for service under the warranty. 

 

They supposedly fixed the issue and it's been working fine until now.

 

It's just now started doing it again and I'm going to have to send it in again while the warranty is still valid.

 

So unimpressed.

Hello! Sorry for the super delayed reply. My laptop was still under warranty, so I sent it back for service last year. It's been working fine since then. Sorry, I can't offer any help.

Ridiculous indeed! Doubly so for me with mine doing this again after being sent in for service for the exact same problem. Crossing my fingers that this time does the trick.
