I was virtualizing a physical machine running ISA server 2006 by using the sysinternal tool Disk2Vhd.

VHD file was created successfully. I attach this VHD in Hyper-v running on Windows 2008 R2 SP1.

While installing Hyper-v integration services, I get the message “HAL Upgrade Required“, try to upgrade by clicking OK.

After sometime, get the message below.

You must restart your system before Hyper-V Integration services can be installed. Do you want to restart now

Even after restart it fails to install the integration services.

Resolution:

Find the boot.ini on the operating system installed drive edit the file and delete the option “Disk2Vhd Windows Server 2003 Standard” then save the file.

Now reboot the guest machine and try to install the integration services it should work like a charm.

IE 9 Windows Update Error 9C48

“Error Code 9C48: Windows Update encountered an unknown error.” 

This error occured when trying to install the following update “Windows Internet Explorer 9 for Windows Server 2008 R2 for x64-based Systems.

Resolutions:

  • Uninstall IE9, if you already have it installed, and restart the system.
  • Disconnect from the internet. This is important because the installer attempts to download the latest, bad binaries from Windows Update.
  • Let the install finish and then restart system.
  • Reconnect to the internet and check Windows Update.  You should be able to see the Cumulative Update for IE9, instead of IE9 itself.
