Bricked by formating all EMMC partitions?

Perhaps have a look here:

Bios/ Cmos Reset

I had the same issue yesterday. Picked up my v4 version from the post office, got home, happily installed Win 10 on the SSD and then decided to delete everything on the EMMC. Felt like a good idea to get some more space! Well ended up in the EFI Shell after the next boot. I couldnt see any hard drives in the BIOS boot order so I tried changing some BIOS settings for the SSD. That made things worse and bricked the BIOS. So I thought I had wasted the computer. But I found a thread here suggesting disconnecting the battery. I did that, waited a minute, reconnected and then I could access the BIOS again. And after that I could boot from my Win 10 installation usb. I reinstalled win 10 at the EMMC and then also reinstalled the SSD.

Can you boot from a usb with the Win 10 installation media?

I solved it by typing exit into EFI Shell and could then jump into EFI settings where I selected my USB Stick with the Windows installation files. I then deleted ALL partitions on my ssd and emmc and installed Windows on my SSD. The setup automatically created a few partitons on my SSD including the 499 MB system partition. The thing is, when you install Windows on your ssd with your already existing system Partition on your emmc, setup doesnt create an extra system partition on your SSD automatically. So your unable to Boot, if you wipe your emmc. If Windows setup doesnt recognize a system partition your emmc, it’ll create a new one if you Install Windows on your ssd. So make sure to delete it first.

Ok, so deleting both the EMMC drive and SSD drive during the Win 10 installation to the SSD solves the problem? Thanks for the information.

I’m pretty sure you’ve removed EFI partition, so now notebook doesnt know what to boot from and drops to EFI console. It’s nowhere close to being a brick.

Here’s how I see it:

You’ve had windows on EMMC, then you had put SSD and installed another copy of windows on it. During install process installer sees that you already have windows installation on EMMC, so instead of making SSD bootable by creating another EFI partition on it, installer used existing EFI partition on EMMC to put info about new OS.

Simpliest fix is just to reinstall windows on SSD (since you’ve already formated EMMC it would make new EFI on drive you point at, i.e. SSD).
