Issue: (1) After Windows install, unable to see network adapter. Light is green where

need to fix 2 before can look at 1. depends on fix really... hence why fixes are backwards

2 would stop my fix for 1... only complication I see is how do you get it to boot off the USB? not boot into windows, but actually run the tools on USB?
You could create the new installer in step 1 and use it to do step 2.. its clear windows has somehow managed to link itself to the efi on the USB instead of making its own when installing. I can sort of understand how that can happen but not seen it before.


(2) If I remove USB stick, Windows does not boot.
fix for 2
  • Boot the computer using the Windows 7/8/8.1/10 installation media.
  • On the first screen, press SHIFT+F10 to bring up the command prompt.
  • Run the following commands at the command prompt.
diskpart
list disk
select disk #
Note: Select the disk where you want to add the EFI System partition.
list partition
select partition #
Note: Select the Windows OS partition (# number) or your data partition.
shrink desired=100
create partition efi size=100
format quick fs=fat32
assign letter=s
list partition
list volume
Note: Note the volume letter where the Windows OS is installed.
exit

bcdboot X:\windows
/s S:
Note: Replace "X" with the volume letter of the Windows OS partition.

BCDBoot copies the boot files from the Windows partition to the EFI System partition and creates the BCD store in the same partition.

Remove the Windows installation media and restart the computer into your BIOS settings and set the SSD as the First Boot Device.

Possible fix for 1:

which version of win 10

  1. right click start
  2. choose run...
  3. type winver and press enter
  4. current version is 21H2
If you on a previous version,
On another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB - that way you know you have the latest version.

put it into PC with windows running
go to file explorer and navigate to the USB
run setup
choose upgrade this PC
it should restart and install 21H2. It should have drivers to run LAN
