I am trying to use diskpart to extend the size from 10G to 20G, but it tells me "diskpart failed to extend the volume. Please make sure the volume is valid for extending."

when i type in "list volume", it only gives me two volumes, one is volume 0: D VBOXADDITIO CDFS CD-ROM 50MB, then volume 1 is C NTFS PARTITION 10G HEALTHY SYSTEM.

should there be a volume 2 as boot? that's what I searched online teaching people use diskpart to partition windows.

Diskpart can't be used to resize the boot volume of an XP system. Use Gparted as discussed in the other thread.

ok, thank you !!
