Can't upgrade HP ProDesk 400 G3 MT to Win10

HP Recommended
HP ProDesk 400 gG3 MT Business PC
Microsoft Windows 7 (64-bit)



I have a HP ProDesk 400 G3 MT Business PC with Windows 7 Pro (64-bit) and I'm trying to upgrade it with Media Creation Tool 1909.


The Creation Tool runs, and after my computer restarts comes with an error 0x8007042B - 0x300D (The installation failed in the FIRST_BOOT phase with an erro during MIGRATE_DATA operation).


Thanks a lot in advance.

Assuming there is a W10 Pro product key in the BIOS, if the upgrade isn't working, the only suggestion I can offer would be to clean install W10.


You can do that by creating bootable installation media with the media creation tool at the link below.


Or you can use the HP cloud recovery client tool to create a bootable recovery drive.


I have zipped up and attached the information below for how to use the cloud recovery client utility.


If you don't know if the PC has a W10 product key in the BIOS, I have zipped up and attached a free utility below that will show you if there is a W10 product key in the BIOS.
