Dell Precision Win10 In-Place Upgrade – “Installation Failed”

“Installation Failed”, what an unhelpful error message direct from Microsoft. If you’re reading this, you’ve probably been fighting with upgrading a Dell Precision Win7/8 OS to Win10, like a T3600, and it randomly stops around 79%, or reverts on initial reboot.

The T3600 I was attempting to upgrade to Win10 was running Intel C600 Series SAS RAID Controller, Dell branded as a RST F6.

The most common error codes you’ll bump into are:

  1. 0x80070032 – 0x50015
  2. 0xC1900101 – 0x20017 – Installation Failed in SAFE_OS phase with an error during BOOT operation.
  3. CheckImageHealthCommandObject::InternalExecute(hr:0x80070032)

You can run SetupDiag from Microsoft to diagnose the C:\$Windows\Panther error logs, but none of it relates to the root issue — Windows can’t find a driver for the RAID controller inside the machine.

There are plenty of posts to run DISM or System File Checker…. like the following.

  1. DISM /Online /Cleanup-Image /CheckHealth
  2. DISM /Online /Cleanup-Image /ScanHealth
  3. DISM /Online /Cleanup-Image /RestoreHealth

If you install Win10 v1903, it will fail on a Pre-Finalize Setup and not proceed. If you install an earlier version, like Win10 v1607, it will install, reboot, and revert.

The solution: Disable the RAID Controller in Dell BIOS, and connect your drive to a standard SATA port (reuse the SATA cable going to the DVD drive). Installing Win10 should now proceed just fine. Some days I hate computers….

  1. I have precisely this machine and this problem. I’ve been at this now for 2 weeks, including putting in an ‘all-nighter’ without success. But where is the BIOS, what is a RAID controller and how do you disable it? What is a stardard SATA port and where is it to be found? Thanks! I am just an ordinary user, not an IT person.
