It does sound as if you have obtained a fake or dud version of xp pro,as for running two or more operating systems on the same computer it is ok to do this but you need a program to PARTITION your hard drive.That is to divide the hard drive into seperate sections which are called partitions.A very good and reliable program to do this easily is Partition Magic,the versions available relate to the size of the hard drive you wish to partition and if after partitioning and installing xp alongside win 98 you decide to remove one Partition Magic will allow you to do so.If you need any further info e-mail me,regards pc fanatic.
