Microserver Gen11 - Intel VROC RAID1 Windows Server 2025 OS install issue (NOT VROC Driver

mr_vaughn — Mon, 28 Jul 2025 01:45:34 GMT

Had case open with HPE Support for over a month. Have had a repalcement systemboard nad CPU and a new Microserver.

Wanted to start this thread.

On a new updated Microserver with latest BIOS,iLO & other firmwares I can flash from iLO. I cannot even get to the first GUI OS load screen to even agree or select install of Windows 2025 Server. This is BEFORE you get to laod the VROC driver to select the RAID Logical Disk to install to.

This is with BIOS defaults or custom.

The BIOS requirement is switching the SATA to VROC and building a RAID1 /10 for OS install.

OS installs perfectly fine using SATA mode. Using the same ISO via & USB ISO imaged install.

This is using the following Windows 2025 Server ISO from Office 365 /Microsoft admin.microsoft.com under the Billing-> Your Products -Windows Server 2025 Standard - 16 Core License Pack

ISO default file name: 26100.1742.240906-0331.ge_release_svc_refresh_SERVER_VOL_x64FRE_en-us.iso
ISO disk label : SSS_X64FREV_EN-US_DV9
ISO MD5: 25bae857ff6ffbaef6604bfdd31d3027

My next steps are to slip stream Windows Update into the boot.wim and install.wim.

Any other thoughts on this would be get.
I also have tried sourcing other trusted MS ISO downloads (even eval) but all are same ISO build number.

Dear mr_vaughn

VROC SATA controller driver is not intigrated with Windows Server OS. that is why during OS installation it wants for driver. When you start installation with only SATA mode it didnot asking for contorller driver.

Please go through the link for HPE microserver gen11 user guide.

Please go through the link for VROC SATA Driver.

Hope, I could provide you with clear and helpful instructions. If you have any more questions or need further assistance, don't hesitate to ask. I'm here to help!

Have a great day!!

rabindra11sharm Please read my post again.

Since this is even BEFORE you load the VROC driver (F6) and mount the volumes..

You know when you 1st boot any Windows ISO... You have a few screens like language, license agreement, etc before you can even select the volume to install. That 1st GUI screen where it hangs.

Hi same problem here.

New server just updated firmware enabled Vroc and windows setup get's stuck before language selectoion. With Sata there is no problem.

Did you find a solution?

Tks

Hi again

With W2022 it's possible to install...

mr_vaughn — Thu, 21 Aug 2025 16:48:13 GMT

Here is the Solution.

You have to merge the latest Windows Updates into the ISO installer.

Apparently there is a know issue resolved with MS Nov 2024 update

https://support.microsoft.com/en-us/topic/november-12-2024-kb5046617-os-build-26100-2314-701f76d0-1127-43f5-a554-f562a940bc17

You have to update/slipstream with Windows udpate into the install.wim & the boot.wim using DISM

There are sites out there that have all the latest updates merged into a downloadable ISO but are a bit dodgy.

Me pasa exactamente lo mismo.

Sin RAID Vroc el sistema se instala y se inicia correctamente.

Cuando configuras el Vroc y creas el RAID. inicies el sistema por F11 desde CD o USB o desde el provisioning se queda colgado en la primera pantalla de instalacion ventana blanca donde deberia de aparecer idioma o cargando ficheros etc, se queda con el circulo dando vueltas en infinito. he probado apretando F6 antes de iniciar, he probado con otra ISO de Windows server 2025 Free, con el CD original de HP Windows server 2025 Rok. Llevo perdidas muchas horas por este error. que por lo que veo ya es conocido.

En fin... Si alguien tiene la solucion y no he desistido del Vroc.

Nota: los SPP estan al dia. con el ultiomo service pack

**Google translate**

I'm experiencing the exact same issue.

Without the Vroc RAID, the system installs and boots correctly.

When you configure the Vroc and create the RAID, whether you boot the system from CD, USB, or provisioning via F11, it gets stuck on the first installation screen—a white window where the language selection or loading files should appear, etc.—it just spins endlessly. I've tried pressing F6 before booting, and I've tried with another Windows Server 2025 Free ISO and with the original HP Windows Server 2025 Rok CD. I've wasted many hours on this error, which, from what I can see, is already known.

Anyway... If anyone has a solution, I'm not giving up on the Vroc.

Note: The SPPs are up to date with the latest service pack.
