Hi. I Want to buy a new DELL Notebook and in the shop on its page is written OS: LINUX . my Problem is : AFter I buy it can I change the oS to windows xp or VISTA?
There are several notebooks which can't be used for anything else than Linux, but yes - in most cases you will be able to change it !
Pay attention to the harddrive - XP has no integrated SATA-drivers so the installation will fail if the laptop has a SATA-HDD
It's pretty easy to patch your XP install disc to include the SATA drivers using NLite. I have a custom XP disc that loads my SATA drivers, so I can install XP onto a SATA drive no probs
Why don't you ask them for the OS upgrade option. Many laptops come with various options and OS is one of them. If you do not have to pay much for the official copy of Win XP, then go for it.
