SOLVED No cmd (F8) in new Boot Image

[AlTu]

I have recently upgraded to SCCM 1606 and ADK 1607.
My old custom boot image still works. It has not been updated by the upgrade process.

I then created a new Boot Image based on ADK 1607. All went well.
However, the F8 key doesn't trigger Command Prompt.

Enable command prompt support is enabled in the Boot Image properties.
I need this to work becuase my Task Sequence is failing with this new Boot Image and I don't really know why.

I would like to examine the smsts.log file.

Did you update the boot image to DP's after making changes ?.

Yes I did.
Yesterday I just re-created the boot image again and this time F8 works.
Really not sure what happened.

So, I was just panicking for nothing

Thanks
