http://askubuntu.com – I have a toshiba satellite L750 laptop with a video card "Nvidia geforce GT525m" on. I would like to "dual-boot" my pc with Windows 7 and Ubuntu 12.04 LTS (windows is already on). I saw from an other discussion Is there a driver for a NVIDIA GeForce GT525M? that there might be some suitable drivers for my video card. Are they suitable for this Ubuntu version? How can i possibly install ubuntu? Do I have to install the drivers first? I tried to install ubuntu from a cd but it wouldn't work Thank you for your help Federico (HowTos)
