so this means i will need some third-party software... ? Since there is an OS on the partition that i want to format and install to... Right now, i just boot into windows 2000 on C:, and i start winnt32 with necessary parameters. Some idea about how I do it best? Since, if i boot with win98 disk, i can not see the different ntfs-partitions, it all looks like one big partition next to a little Fat32 one. thx in advance
