Hello,

we have about 400 Windows 10 VDIs in use. We are currently trying to install the upgrade Windows 10 1809. Our hard disk controllers are available as SCSI controllers. During the upgrade the virtual machine gets stuck in the boot screen and does a rollback. The failure “The installation failed in the SAFE OS phase with an error during the INSTALL_UPDATES operation” appears.  If I connect the hard disks to the IDE controller, the upgrade works. The latest VMWare tools are already installed (10.3.5). But we wouldn’t like to switch all VDIs to IDE controllers. Is there a general problem?  I hope someone has an another idea. Thanks in advance.

With kind regards
Dominik Geb
