Yes I do. The exact same setup worked for nearly 1.5 years until I upgraded the BIOS. I made sure that, post CMOS reset, the required options were all enabled.
I've decided to convert to dual boot rather than experiment with the BIOS. I have no desire whatsoever to brick the damn thing - especially not now as I've got other, far more important priorities to focus on and don't want to have to go through the purchase-install-configure cycle again.
Fortunately Linux is a fantastic tool to be working with so I managed, rather easily, to dump the VM images to a single HDD and have since confirmed it all works fine.
The takeaway for me is as follows:
1. I will not buy into a vendor who places restrictions on downgrading. I understand it may be needed sometimes but other vendors are far more liberal in this regard.
2. I will need to dig deep before upgrading BIOS etc. which is a real shame. I do not aspire to knowing the inner workings of every software framework out there.
3. I might reconsider running on AMD stack. I've been a long-term user but I hate surprises of this nature. Hence my server runs on Xeon rather than AMD equivalent.
Thanks for your quick inputs - much appreciated!
