Resizing the root partition in Ubuntu

[mayank2013]

Hi I am fairly new user to Ubuntu and recently installed 12.10
But during installation, i was checking the partition space and it by default kept 930 GB to Ubuntu partition

Can you guys suggest how do i go about fixing it and what should be the ideal partition...

So now the current status is :

Partition File System mount point Size Used Flags
/dev/sda1 ext4 / 923.5 GB 20 GB Boot
sda2 extended 8 GB
sda 5 Linux Swap 8 GB

Please help out, after this i need to create a new virtual box for Windows 7 , bcoz lot of my ollege work is in wondows

Moved to your own thread, old one was old.

I prefer to make / (root) 25GB and then allocate remaining parts of drive to /home or data. I have seen some with separate partitions for VMs, but have not done that myself.

You can shrink / with gparted from LiveCD.
