 ## Booting the generated program
 
+Note: producing VHDX requires running from an elevated command prompt. It will not work without elevation.

 Running `build.cmd` should produce a BOOTX64.EFI file in the current directory. There are multiple ways to run this. QEMU with an EFI firmware should work. I use Hyper-V.
 
-Running `build.cmd vhd` will produce a VHDX file for you that you can run on Hyper-V directly (it prompts for elevation, so don't be surprised). You need to create a new Gen 2 virtual machine in Hyper-V and attach the generated disk. Make sure to turn off Secure boot in the virtual machine: the EFI image is not signed.

 Similarly, adding `-p:BuildVHDX=true` to the `dotnet publish` line (when using the `*.csproj` project) will produce a bootable VHDX.
