To Increase the hard disk size of OS in Parallels (Mac OSX)

Refer the link:




In case, if you dont find it there:

1. Find your hard disk image file on the host machine (in this case Mac OS). Run the Parallels Image Tool.app on it and expand it to the desired size.

My Parallels disk image is located in:

~/Library/Parallels/Microsoft Windows XP/winxp.hdd

These days, Parallels is installing that image in:

~/Documents/Parallels


2. Use the Finder to duplicate the hard disk image you wish to expand.

3. Open Parallels but do not start Windows. Open the Parallels Preferences for the virtual machine. Change the hard disk image path to the duplicate image. (Note, this is not the "Default Folder for Virtual Machine" setting you first see. It is the Hard Disk setting, lower on the Preferences screen.)

4. Add a new hard disk via the Add button at the bottom of the screen. Set the new hard disk's path to the original image. The purpose of this and the above step is to boot from the duplicate disk, so that Windows can have full access to the disk (original image) you wish to expand.

5. Boot up Windows. Windows will report that it has identified new hardware. After that is finished, then navigate to Start -> Run. Type (no and no quotes), and press Run/Enter.

6. In the new window that appears type:

7. After that process runs, a list of disks appears. Notice that Volume 1 and Volume 2 look identical. Note: Volume 2 should be the original hard disk image.

8. Select Volume 2 by typing: select return. Then extend it by typing . Once that is complete type exit return. Then shut down Windows.

9. Before starting Windows, clean up the Virtual Machine preferences by using the Parallels preferences to delete the second hard disk, and to switch the Hard Disk 1 path back to the original hard disk image. You can put the duplicated Win XP hard disk image into the Mac Trash.

10. Restart Windows. Rebooting may be necessary if Windows "detects new hardware."
