I've installed fedora 10 on my PC yesterday along with Microsoft XP SP2...after a lot of struggle i finally got through with the installation and i used it for a shprt while..then i switched to XP a short while later,then i found an error on start-up saying some boot error!!
Then i re-installed XP and i found that the choice for fedora boot on startup was missing!!! I need someone to help me out..the OS is installed but its not booting.. i saw some refernces of 'grub' mentioned on googling..but i can't sort this out still!! pls help me!!!
P.S.:I'm an absolute newbie so pls be clear with your replies!!
Thanks in advance!!!
