Attaching a VHDX file

---

Hi,

I need to add a VHDX drive to a new hyper-V VM, do I need to grant the new VM's SID access to the VHDX file if so how?

@Dan-Wages , I hope all is well. Depending on exactly where you are in the process, and what you have done/want to do, the following should be helpful to show you what to do, and what order to do it in:

Good Luck !!!
