Y40-70: Default Boot Device Missing or Boot Failed

Good day.

My computer (Y40-70) prompted me "Default Boot Device Missing or Boot Failed". I tried booting with "Legacy" on but it still did not solve my problem. Any ideas on how to fix this?

Thanks.

hi uynauk

 

Welcome to the Forums.

 

If the machine came preloaded with Windows 8.1 then your problem is likely similar to this thread.

 

Can you try the suggested options to fix the Default Boot Device error.

 

 

Let me know how it goes.

 

Regards

Hi.
Thanks for your quick response. 
I tried attempt #2 and #3 but it still did not work.

hi uynauk

 

Just to check, when you tried Option 3, were you able to finish the OneKey Recovery? As for Option 2, did you wipe all of the partitions and format the drive or did you perform a repair installation as discussed in this article?
