Poweredge R520 UEFI Hyper-V - Too many partitions

We have a brand new Dell Server (R520) 32GB of ram, with 4 x 2TB hard drive, raid 5, usable 5.5TB's or so, I would like to install Windows 2008 Hyper V server. The issue that I am having is that I only want two partitions, one 160GB and the other the rest of the 5TBs, when I use the lifecycle manager it will allow for two partitions, but won't find the boot option for my hyper v, unless I choose BIOS mode, but when I do that I have to make several partitions no larger then 2TBs, what OS in the lifecycle manager do I choose?

Please advise me for the install.

Thanks for your time.

you need a gpt drive not a mbr drive
I'm guessing you want to use hyper-v as the base operating system. When you boot the system you will be presented many options and you must boot with the EFI boot and not the legacy cd/dvd boot option.

subsequently you will get an Microsoft boot option in your boot preferences. You will then use it from now on once the OS has been installed.

If you have previously initialized and partitioned the drive you will need to goi into diskpart from the f10 command prompt and then clean the drive

sel disk 0
and then refresh the drive selection.

if need be, you can just install the operating system (hyper-v) and from diskpart shrink the disk to your desired size then create a new volume (5.5TB)
