Server OS installation failures

HP Recommended
HP Z8G4
Microsoft Windows 10 (64-bit)

Hi,

 

I've got an HP Z8G4 system that came preloaded with Windows 10.  I need to get a server OS installed on it.  I've tried Server 20196 standard and Server 2019 standard.  Every time I try to install the new OS, the setup program gets to the point where it needs to reboot the system.  It reboots, then I get an error message: "UNMOUNTABLE_BOOT_VOLUME."  System automatically reboots again after that and restores previous OS.

 

I've spent several days searching online for a solution.  The most common one I see is to re-install the OS, but installing an OS is exactly what I'm doing when I get the error.

 

Any other advice?

 

Thank you,

Hi, @TMG9804 

 

See if this HP support document is of any help to you...it is for installing Windows Server 2016 on various model HP Workstations.

If not, perhaps @DGroves or @SDH who both have a considerable amount of experience with the HP Workstations, can be of help to you.

error message: "UNMOUNTABLE_BOOT_VOLUME.", is usually seen when the Drive itself has a problem.

 

if possible remove the drive and connect it as a secondary drive in a working system and run the drive makers diagnostic tools on it

 

this can also be caused by a hardware incompatibility between the server install media and the system it's being installed to

what is the systems hardware config?

 

have you tried new install media from microsoft?  (select ISO) not Azure from this page

last, a clean install is required you can not upgrade from win 10 prof to a server OS as this will cause all sorts of weirdness
