Windows cannot complete the installation

if you have the recovery disk or recovery partition in your hard disk then that can help....
else you can ask if someone near and dear have the cd of windows of same version then that can help

It happened to me too 2 days ago. I suggest you check the manual that came with your VAIO laptop. Specifically, check out the pages on "how to restore your computer when windows does not start." It explains how to do it using your recovery discs or your laptop's recovery partition. I probably would have gone to the repairman had I not bought some time out to read the manual again. It certainly saved me money and gave me a big sigh of relief.

You also have the option to Clean Reinstall - Factory OEM Windows 7 which is a superior reinstall without the factory bloatware and useless OEM utilities which have better versions built into Win7.

Until that happy day you can Clean Up Factory Bloatware - Windows 7 Forums
