Help upgrading in-place 2016 to 2019 on microsd boot setup

Hello everybody! :)

 

I am trying to do an in-place upgrade of my Gen8 to W2019 but I am not having much luck with that/

 

1. I have a SSD connected to the OOD bay as the OS disk (running 2016)

2. A microsd card with the proper bcd config to boot the OS from the SSD.

 

 

When trying to do an in-place upgrade, I get the following error on the setup:

 

"We can't tell if your PC has enough space to continue installing Windows 10."

 

And that's all! I am pretty sure this is due to :

 

Microsoft Windows [Version 10.0.14393]
(c) 2016 Microsoft Corporation. All rights reserved.

C:\Windows\system32>bcdedit /enum
The boot configuration data store could not be opened.
The volume for a file has been externally altered so that the opened file is no longer valid.

C:\Windows\system32>

 

But I cannot figure out how to "trick" the installer into seeing the BCD store on the sdcard (assuming this is the issue).

 

Any of you managed to do an in-place upgrade on a similar setup? I would like if possible to avoid a full re-install (i don't even know if I would be able to setup the microsd boot again from scratch :( )

 

Thanks a lot!!!

Silly question. If I buy a pci-e sata card and connect the ssd there instead to the ODD drive, would I be able to boot from the pci-e card in AHCI mode? Maybe that's a less painful solution... I should be able to repair the bcd using a repair disk to be able to boot again from the ssd, but I don't know if AHCI mode BIOS allows to boot from a pci-e card.

Something like this: ref=sr_1_1?keywords=pci-e%2Bsata&qid=155

A SATA controller that is bootable should be able to do that. You could add a SATA/SAS HBA and connect the the swappable bays to it. Then add a breakout cable to the SATA controller on the system board and boot the SSD from that in AHCI mode. There are several ways you can make it work if you add a controller.

Power off, pull the drive bays, then the OS will install ok on the SSD.

 

Then just reseat the drive bays and off you go.

 

I had to do just that with each major upgrade of Windows 10.

@schoondoggy: Thanks for confirming this, this should be a good workaround.

@psykix: Of course! Removing the drives will force boot from the ODD :( I completely forgot! I'll try this and report back. Thank you so much!!!

You may have to change the boot order to SSD first if it still refuses to install - I can't remember if it worked with just pulling the drive bays or if I needed to actually boot direct from the SSD
