Warning
The used space of the partition to resize must not be larger than the new size.
To resize the partition, use the resize command followed by the minor number for the partition, the
starting place in megabytes, and the end place in megabytes. For example:
resize 3 1024 2048
After resizing the partition, use the print command to confirm that the partition has been resized
correctly, is the correct partition type, and is the correct file system type.
After rebooting the system into normal mode, use the command df to make sure the partition was
mounted and is recognized with the new size.
