UEFI or BIOS mode for a new Dell server running server 2019?

[TwistedHelixis]

Sorry, this could have got posted in a number of different forms, so please move if needed.

 

Just about to order a new server and will probably install server 2019 as a GUI host with 2019 VMs.

 

So, over the years I have asked this question and each time I get a different answer.

 

When the new server arrives should I set it up as UEFI or as BIOS?

 

Obviously this choice has an impact over the lifetime of the server, which in the primary schools I look after can be 10 years.

I would go UEFI. The vast majority of our machines are UEFI - clients and servers.

Definitely UEFI.

 

MBR-partitioned boot drives cannot be larger than 2TB so going with UEFI is a no brainer.

BIOS supports only MBR-initialized disks to start the computer. To restart from a device that is initialized by using GPT, your system must be UEFI-capable.
