Owing to bad planning and lack of foresight, I messed up primary/logical partitions on my new 1TB HDD.

I need a dual boot Ubuntu and Windows, and one 100gb unallocated space just sits there in the middle.

I was thinking of merging it with the other unallocated space and install Windows on a logical partition, while Ubuntu remains on primary (is that even a good approach? )

Following is my GParted current view,is it possible to delete everything on the hard drive, all the partitions and start afresh by creating partitions from the beginning?

Thanks in advance!

  • I am fine with that. Do you mean I should put in the usb stick, boot in the live mode, and it will give me an option to wipe it all away? – Aman Alam Jun 29 '15 at 7:37
  • I believe windows likes to be on a primary partition – mchid Jun 29 '15 at 7:43
  • Boot from the Ubuntu installer, open GParted and delete all partitions. Then you can start anew... – s3lph Jun 29 '15 at 8:54
  • Why not just create another partition? – VRR Jun 29 '15 at 15:47

If you don't mind to reinstall, I propose to reinstall instead of dealing with Gparted and all those partitions.

  • Boot into Ubuntu Installation media. This can be either CD or USB stick.
  • Start the installation. Proceed to Step 4 and choose "Something else":

    Step 4 — Something else

  • You will see your disk as /dev/sda

  • Click "New Partition Table..." You will see that you have free space on your disk now:

    free space

  • Create partition for swap if you want to use it(recommended)

  • Select free space and click + and set parameters

  • Create partition for /

  • Select free space and click + and set parameters

  • Repeat the same steps as many times as you need partitions

Then move on and complete your installation


You can find information on Dual Booting Windows and Ubuntu here: https://help.ubuntu.com/community/WindowsDualBoot

It is recommended that you first install Windows and then Ubuntu.

Also, Ubuntu gives you an option to create a new partition table, when you install.
