  • i think the partition is faulty , it is not readable , i think it has been corrupted badly . when i am trying to delete the partition it shows "Please unmount any logical partitions having a number higher than 5" . Does this relate to the partition name ? because the partition having windows 8 is dev/sda5. i deleted windows 7 partition successfuully . But i cant even mount this partition now so cant delete the boot files . :(

Just delete the Windows partitions with gparted.
Make sure to open gparted as root.

if you don't have gparted installed install it by typing sudo apt-get install gpareted in a terminal.

Start it with sudo gparted and edit your partitions.

The most simple way for you to do it is trough graphical interface:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Afther you install the program you will be presented with all the boot options, remove rom that list windows 8 and 7. Afther that you have to physicaly remove them from your hardware.

sudo apt-get install gparted

Now press the super key, type gparted and open it. You should get something like this:

enter image description here

Now just make sure you chose the corect partition(for windows 8 aor 7) and press the delete button and you will delete that partition.

For a graphical tutorial just go on youtube : GParted Tutorial

  • Pls provide a screenshot with what you want to do. I think the problem is, if you have a partition for example sda2 and another one sda3, and sda3 was made from sda2 i think you have to delete first sda3 and then sda2

There is a simple solution, only takes 10-15 minutes. It worked for me several times.

SOLUTION:

  1. GET A WINDOWS 7 OR 8 INSTALLATION DISK.
  2. BOOT WITH THAT DISK{just like windows installation}
  3. When installation reaches hard disk partitions menu......
  4. Format the drives in which windows 7 and 8 are contained.....

NOTE DO NOT FORMAT OTHER DRIVES. IF THE FORMAT DOESN'T COMPLETES. JUST DELETE THE PARTITION AND RECREATE IT.
