Windows server 2019 installation problem

[Tylerebowers]

Trying to install server 2019 on my HP dl360p g8, currently I have two 4tb drives in RAID 1. When I try to install windows it limits the install to 2tb (because of MBR). I reinstalled but this time I used diskpart to convert the volume to gpt but It still did not let windows install to the full 4tb, still only 2tb. I have reinstalled several times still no luck.

What are you using as an installation medium? Sometimes how you create the bootable media determines weather it defaults to MBR or GPT.

 

Do you know if the server supports UEFI or only Legacy BIOS?

I was using a usb cdrom, but I also tried a usb drive. It is a Legacy bios.

This would be part of the problem. Some Googling says Windows does not support booting GPT disks with Legacy BIOS.

 

It appears there may be work-arounds for it but your results may vary. I came across this little passage. May provide some useful information.

The server doesnt support uefi booting, so I am just using MBR and Segate Beyond 2TB to make two partitions. Maybe ill have to upgrade to the gen 9 for uefi booting.

So long as you don't mind telling your applications to use the D:\ or E:\ disk the performance will be identical. It's only a mildly annoying work-around.

Normally the raid cards on those let you make multiple volumes per raid volume. Make something like a 500gb for boot, and the rest of the 3500gb in a dta partition.

This ^ 

Or better still, get 2 small SSD's to create your boot. You can get 120GB ones second hand for really cheap these days...even brand new you can get them for ~$30

Legacy BIOS does not support GPT partitions, only MBR and therefore has a 2TB limit. This is actually part of the reason why UEFI was created, they realised that limitation was going to become an issue.
