RESOLVED... Yoga Book YB1-X91F Boot Manager Failed

Some time ago, I was installing new software and I believe what happened is that storage filled up.  Ever since, I'm getting this message upon boot up:

 

Windows Boot Manager boot failed.

 

When taping OK, I get a different mesasge:

 

Default Boot Device Missing or Boot Failed.

Insert Recovery Media and Hit any key

Then Select 'Bookt Manager' to choose a new Boot Device or to Boot Recovery Media

 

Then, tap OK which brings up a boot option menu.  There are two options, EFI Boot Devices and Windows Boot Manager.  My plan is to create a USB boot image and boot from that but to select EFI Boot Devices, It requires using the up/down arrow keys.  Unfortunately, the halo keyboard isn't lit so I can't do that.  Taping EFI Boot Devices won't work.  the only think I can tap is the OK button which just tries to reboot and goes back to the initial error.

 

Does anyone have any ideas on how to restore my device?

I managed to fix this.  I created a bootable usb stick.  When I restarted with it attched, it asked if I wanted to updat or clean install.  Choosing update did the trick.

Hi! How did you manage to create a bootable disk?
Was it through the recovery image or just the "normal" Windows ISO?
