Windows 7 Installation problem with Sony Vaio

What exactly is it you want to do in the Command Prompt?

The Sony instructions for running Recovery Disks don't say anything about it requiring the Recovery Partition to run. This is why Recovery Disks are made - in case HD and/or Recovery Partition fails.

You said earlier you have this Recovery Disk set. Try running them now following Sony's steps: View Document

If this fails find or borrow a Win7 installer for your licensed version to clean reinstall using Product Key on COA sticker: Reinstalling Windows 7

How to use a OEM manufacturer's Product Key (COA):
Clean Install : Factory COA Activation Key

Hi,

Thanks for all the help.
Since I am still in guarantee period, do not want to perform anything myself.
Am trying to get someone from Sony as i am under international warranty too.
Will update soon on the status.
