I have a computer with a hard disk that contains two partitions. One partitition was FAT32( C drive) on which windows 98 was installed and the other partition was NTFS on which windows xp was installed. Things were working fine until windows 98 was affected with a virus. After removing the virus I observed that the system was very slow. So I saved all the files in the root directory of C drive and formatted the C drive(FAT32 partition). Now the problem is that I cannot boot the windows xp. I am not getting the boot menu from where I can select which operating system to boot. Is there any way by which I can boot the windows xp installation, without a re-installation ?
