Re: windows 7 installation problem
You need to enable the virtual disk service before performing the upgrade if you hit this error.
1. Click Start / Run and type SERVICES.MSC
2. Look for the Virtual Disk Service
3. Right click it and choose "Properties"
4. Make sure the Startup Type is Automatic, then click the Start button.
5. Reboot and try the format again.
Start | Control Panel | Hardware and Sound | Device Manager.
Then I selected Disk drive and double-clicked on my hard drive, which brought up the Properties window for the drive.
I clicked on the Volumes tab and noticed there was no information displayed there whatsoever. So I clicked the
Populate button, and poof... like magic all the volume information correctly appeared.
A google search to help you-
Windows could not retrieve information about disks on this computer - Google Search
