How to change Korean Sony Vaio SR25

Hello,

I own a Korean model of the Sony Vaio SR 25, with Windows Vista, which has only been sold in South Korea as far as I know.

Now as I never got fluent in Korean and have big problems understanding the characters I would really like to change the language to English. I already tried a language changer tool I found online, which changed the language at first but then caused a few bugs. Plus, after the first restart my computer reinstalled Vista with its internal recovery CD setting everything back to the original Korean installation as before.

I want to install an English version of the recovery CD and Vista. Is that possible? Where would I get the English recovery CD data?

Thank you in advance. I appreciate any help!

Loui
