Thanks for your reply.
Thanks for the suggestion, I have just spent some time playing with the various options in the config file to see if it helps, but I’m still not really getting anywhere.
If I use REFInd as the default exist option for UEFI then I end up at the About REFInd screen, which I guess indicates it can’t find anything to boot.
I have tried enabling the scan_delay option, putting it to 5 seconds, but that doesn’t make any difference.
I then tried enabling scanfor internal,hdbios, which did detect something to boot, but I get the usual “nothing here to boot” screen when trying to boot from a drive with nothing on it.
What did help, was enabling the deep scan, which then showed me 2 bootable options, 2 second of which is the windows install I was looking to boot to.
So, that seems to work. However this config is now causing issues with the other machines that don’t need this enabled to work fine, they throw an error about not having the modules available for this, which blocks the automatic booting into windows for them.
Is their any way for me to target specific machines with different settings?
