Hi, Please help me! My brother has 3 STA HDD and Windows 7 OS. Disk0 [Primary C: (Windos 7 OS)+ Extended(Logical) D :] Disk1 [Primary E:+ Extended(Logical)F:] Disk2 [totally Unallocated] Now want to create a Primary and a Extended(Logical) partitions on Disk2. Primary Partition( G: ) has been created without any problem. But when I R-Click on Unallocated Space(Disk2) at Disk Management there is no option for Extended Partition only Simple Volume option available(which gonna make another Primary Partition). So,how can a make a Extended(Logical Partition) on Disk2 ? Is it not possible on at Windows 7 mode ? Do I need a Bootable Disk of third party Partition Application for that ?
