i parted my hard drive and shrunk the new partition in attempt to recover the space ,how can i undo the shrinking and the partition
To change the partition sometimes you can use the “Disk Management” Tool in Windows. Press the Windows button on the keyboard and the X key at the same time and then choose “Disk Management”. If you right click on a partition you see the options you have. Be aware that you should backup the files from the partition if the are important to you since there is a risk of loosing them if something goes wrong while changing the size. You can normally not change the system partition C in windows. Then you would have to get a live CD/DVD of a Linux OS for example and when you have booted from that you could start a partition program like “gparted” and change any partition on you computer.
