[EN] BareMetal nanoserver – Boot Media Preperation (SD-Card)

Dear Community Reader !

This blog is about installing nanoserver on bare metal (HP MicroServer Gen8 in my case).

HP MicroServer Gen8 G1610T 2,3 GHz

This device has many boot-options, i.e. Disks, USB Ports, Network cards and also an internal SD-Card reader.

I found the idea to boot a nanoserver from an internal SD-Cards charming, because it could be prepared on a workstation, is then stored inside the microservers case (see pictures) and the disks and SSD´s can be fully used for data and applications.

As we are here in a PowerShell blog, the frame conditions for this (and subsequent tasks are):

  • Do everything in Powershell (no command-prompt programs)
  • Prepare the boot media from a Windows 10 Workstation (no operations on the server itself with Preboot execution environment)

When dealing with boot-media, you need to differentiate between BIOS (old-Stype Basic-Input-Output-System) or UEFI (the new computer bios type). Both need different partition schemes of an SDCard to work.

The HP microserver Gen8 has a traditional BIOS, so we need to prepare a BIOS type Partition.

Start a PowerShell Session as Administrator.

Furthermore it is impoortant to know that managing more than one partition on a USB/SDCard is only possible with Windows Creators Update (march 2017) Version 1703. 

So for creating BIOS-Type bootdisks, this doesnt matter, but if you plan to create a multi-partition UEFI Drive, please make sure you have Creators Update installed.

If your computer is capable of booting with UEFI Bios, the following code with create the necessary partitions

Thats it! – Next steps will be to prepare the nanoserver-image for the server. Watch out for the next blog…
