I'm using Wubi 12.04. When I installed, the disk size was 18 GB. Now I'm almost running out space. But I have enough space in Windows drive in which I installed Wubi.

I tried to increase the size of Ubuntu from this link:


But it gives the message:

wubi-resize.sh: The new size (5 GB) isn't sufficient to hold your
wubi-resize.sh: existing install (18 GB) plus a freespace buffer

What should I do?


You are trying to make the disk smaller (according to the posted error log, 5Gb). Try to make it bigger than 18Gb!

  • Need your immediate help pls... I missed this step. as I now checked it and found out that in ubuntu the disk size didnt increase but from windows drive the disk size had been decreased... 6. You're done! Reboot into windows, rename the file \ubuntu\disks\root.disk to \ubuntu\disks\OLDroot.disk and rename the file \ubuntu\disks\new.disk to \ubuntu\disks\root.disk. Then reboot back into Ubuntu -- only delete the OLDroot.disk if you are sure it worked. – lara Dec 13 '12 at 9:54
