@vanopy For reference here is the guidance on setting up a 2012 server for dynamic support for both bios and uefi systems: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy

I would make sure you have filters for both type 0007 and 0009 uefi systems (bc and x64) because both are common in environments.

The tftp logs of course show that a bios file was requested, so that may be why the vm failed to pxe boot.

@vanopy I’m still thinking its a disk error. You may need to boot it back into Windows and run some disk repair utility to see if 1. you can detect the error in the OS and 2. repair the error. The fog suggestion that disk space on the server is the issue is incorrect.

Ticket can be closed for me.
I’ve captured a completely new image, before doing so, I’ve shrunk the disk, just to make sure.
Deployment is now working as expected for me.
Thanks for your assistance.
