How do I restore the preinstalled windows7 in Vaio laptop after format

Hi everyone ..

I have a problem in my vaio laptop i7, I used to have the preinstalled windows 7 home premium but i mistakingly formatted the recovery partition while installing Ubuntu 11.04 in the machine.

Previously I have made 4 discs which are the recovery discs. The current problem is when i insert disc#1 the recovery process stops at 9% .. I was able to get the partition back by setting the BIOS into the default value. but still it cant seem to be restoring..

any guidance would be much appreciated ..

Thanks :)

All Linux code must be deleted using the CLEAN ALL command.As you have had linux on the HD you need do a Clean all & full format.

Try a full clean & full format in command prompt.
1) Boot DVD & Press Shift+F10 (for command prompt)
DISKPART : At PC Startup
2) Boot DVD, & Command Prompt at Startup
(for command prompt)

Type in command line
DISKPART
LIST DISK
SELECT DISK # (win HD)
CLEAN ALL
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT fs=NTFS
ASSIGN
EXIT
EXIT




SSD / HDD : Optimize for Windows Reinstallation

Thank you very much theog for the wonderful explanation, i just finished the steps mentioned but i still have the same problem, when i choose the recovery option it starts with formatting and then restoring which stops at 9% and does not move further. the CD tray suddenly stops spinning the disc but the hard disk LED is always blinking and on because of processing..

I need some help ..

One of your Sony Recovery Disks may be a bad burn.
1) Clean the DVD Drive.
2) Clean the DVD Disks.

How to order Sony Recovery disks:
1.Go to http://servicesales.sel.sony.com.
2.Enter your computer's model number (for example, PCV-XXXX), and click List Parts and accessories.
3.Follow the online instructions to order the Recovery Media Kit.
If you are not able to access the Sony Direct Accessories and Parts Center Web site, contact a customer service representative at 1-800-488-7669.

Thank you theog for the quick reply, yes it seems like a problem in the dics. I couldnt access the web address mentioned. when i contacted the customer service online, they directed me to contact www.hermanelectronics.com to buy the recovery dics whereas i stay out of the US at the moment.

Thank again mate for the help :)

The link is OK from the UK.

inaccessible in Malaysia .. probably something wrong with my browser!

Find a Win7 installation DVD for your licensed version and reinstall with the Product Key on COA sticker. The detailed steps are in the link below in my signature.

Thank you gregrocker for the suggestion, that was my first solution i tried before i do anything else, I managed to update and everything is good, but it is not the Vaio edition of Windows 7, hence its not what i am looking for. But thanks anyway for the reply .. :)

I just called Sony center in The US and they said they don't have the CD recovery for the model, plus if they have they wont be able to send it overseas, both ways I have to look for an alternative.

any suggestions ?
