I have just added XP onto a new disk and want to format the old disk with XP, when I try I get the message "this disk contains operating system cannot formt" or words to that affect. How do I format my old disk? Anyone. Thanks.
Good point, didn't think about that.csmager said:If it's telling you it's the system disc, then it still is. It might not have the OS on, but it probably has the bootloader on it. Formatting would probably cause your PC to stop booting...
