No. Both the Windows installer as well as the Fedora installer will see both of your hard disks and allow you to chose which one to use for the install(s). > - Is it possible to install Windows on the second HD ? Somebody else might want to give more detail here, but the last time I was confronted with this, it was better (or even the only possibility?) to install Windows on the primary and Linux on the secondary hard disk. > - When I have to install Grub, what do I have to choose ? the MBR or the The MBR. This will make sure that Grub is the first thing you see upon booting, so that you can select which OS you want to start. All in all, I'd recommend this: Make the 40 GB hD the primary master and the 80 GB HD the primary slave (or better secondary master) on your IDE bus. First install Windows on the 40 GB thingy, then - after this is working - install Fedora on the 80 GB drive. Let Grub install itself into the MBR and everything should work fine. Greetings, Nils
