Windows 7 works with a activation code (yeah, big news
). So you just need a clean Windows 7 [your version] dvd. You can install any language with your code. with clean I mean no HP version, Toshiba, or what so ever. (also no cracked or adjusted, just the normal dvd)
You install it. Login. After you did this, go to computer properties and change the code to your code. Now you can activate it, and you have a legal version. After this, you will have to install ALL your drivers, I mean ALL. Go to the site of your laptop brand , it should be easy to find.
of course, this will mean you lose all the pre-installed software.
If you are lucky, you can use the recovery dvd of someone with the same laptop as yours since the activation works with a code. make sure it is exact the same. You can do this by checking which recovery dvd he has to buy. this is determed by the product number of your laptop.
In any case, you better make a recovery dvd on your own, to avoid all this.
as for reply on writhziden:
ubuntu was not able to run e2fsck (yes I checked with wine (the windows emulator).
f11 didn't do anything new, because it ended up with the same recovery manager.
also: I once used the recovery manager on the partition on my windows even with ubuntu installed. But this could just be luck.
anyway, thanks for the response
and sorry for my bad English
