Windows Installation Not In English

My girlfriend has a new-ish laptop that came with Windows 7 Home Premium, and recently it had some issues. The issues have got worse and it turned out to be a stuffed drive, out of warranty, its basically stuffed.I got a new HD and installed it, but when i went digging for the Windows disc that came with it i couldn't find it. Some googling tells me that this laptop does not come with any install discs (seriously, wtf?!) only some manuals and other paper work. There was however a recovery drive which i assume was a partition for re-installing windows and the rest of the included bloat ware. Without a Windows 7 disc we could not install it on the new drive, so i downloaded an ISO on my machine and created a DVD, but the idiot i am, i downloaded it in the wrong language. I didn't notice the NL at the end of the file, which im assuming is Netherlands? Please excuse my language ignorance if im wrong.I know downloading software is wrong, i dont need a lecture. I'm just not going to pay for another copy of Windows 7 because the scumbag laptop manufacturer wont even include a bloody install disc!I have the product key of course, luckily the sticker on the bottom of the laptop was still visible.Sure i could download another ISO, but being bad once is enough for me and our net is pretty slow.
