I'd Fedora7 & WinXP. But, as result of some trojan attack on WinXP, i tried to format the partition having Fedora7 throught PartionMagic and didn't respond. So i restarted PC using WinXP CD but screen went blank for more that 30 mins. So i removed and restarted without any CD. LINUX started but not WinXP. So i again tried to open WinXP in Safe Mode, Win XP isnot opened nor through win any startup options, rather it's saying remove any installed OS.
So would like to know how to uninstall Fedora7 and reinstall back WinXP???
