I am a total beginner to the world of Ubuntu. I would like you people to help me on how to dual-boot 12.04 on a computer already running windows 7 Ultimate.

I have:

  • dual core processor,
  • 2GB RAM,
  • 500GB hard disk with
    • c occupying 100GB (Windows is over here),
    • d having 180GB (all other stuff like movies, songs and stuff),
    • e having 185GB (totally empty).

I would like to install it on e by allocating 30GB (25 for root and 5 for swap) to it by partitioning the disk .

The problem is that when I select Something Else option it shows all the disks properly but when I select sda4 i.e. local disk e, the Add option does not respond. Only Change option responds on that window.

I'm totally confused. Please help me on that. Is GParted a good option? If yes, then please elaborate. If possible please provide screen-shots of everything.


You may have 4 primary partitions, the maximum allowed.

After you select "Something Else" change sda4 from primary to extended. Inside the extended partition create three logical partitions, one for root / (25GB), one for swap (5GB) and one for /home (rest).

Partition types for / and /home should be ext4 and swap should be swap.

The rest should be easy.

Hope this helps.

Maximum primary partition allowed is only 4 partitions on each drive. Try making logical partition that allows you to create way more partition than primary and I will recommend you to move your partition that without OS (for data only) to logical to easily manage your drive. I will use Gparted from the live cd instead of the installation one, because it's MAYBE more safety and more user friendly.
