You can't partition a systems drive using XP,you need 3rd party tools such as Partition Magic (not free) or Gparted free download as iso file.
it seems to be easy but I simply don understand. I have a new PC, it has only 1 partition, so I want to create another. I ve installed XP, and went to Control Panel-Adm. Tools-Comp. manag.-(on the left) Disk Managm. Thats exactly what Help tells me to do (Help search: partition, result: create part. or log. drive). But, NOW it begins. Help says: Right-click an unallocated region of a basic disk, and then click New Partition. But WHERE to click?! I have been clicking everywhere and can not come to this message. I am desperate. Please help. THX
