From a recommendation from my teacher I will be switching from Ubuntu to Fedora. Now I have a dual boot of Windows XP with Ubuntu 8.10. I use GRUB as the boot loader. Now I think that the installer will install over my current partition (L:\ on windows) and install Fedora over Ubuntu but what worries me is GRUB. Will GRUB still be up and running and show Fedora instead of Ubuntu or do I need to override my current GRUB settings with the GRUB settings from the Fedora installer?
