Step 6. Format your disk

  • This is the tricky part. If you are not sure how to partition and format your machine then just choose the default Replace Existing Linux System(s).


  • Tick Review and modify partition layout if you want to make sure you are formatting the correct partitions. This is just to play safe on where you are installing Fedora. You backed up your data anyway. You backed up, right? Didn’t you? If not, back up first and go back to Step 1!
  • If you have a multiboot system like a separate Windows partition verify in this step that you are not overwriting it.


  • You will see at least two physical disks (more if you have more hard disks) one is your physical hard disk the other is your live USB.
  • Choose the hard disk and click the right arrow.


  • Click Next.


  • You will see your existing partition layout. Click Next if you prefer the same layout as before.

  • Otherwise, if you want to change, you can click the partitions you want to edit.
  • In my case, I want to move /home to a separate physical volume so that in my next upgrade (hopefully not so soon), I will not be forced to format it again. If you notice here both root (/) and home (/home) partitions are in the same physical partition sda6 so upgrading root means formatting its physical disk thus affecting home.


  • In this new layout, the root partition vg_georgie_root is in its own physical volume sda6. Similarly, the home partition vg_georgie_home is also in its own physical partition sda7. Do note that the root partition must still be divided into at least two logical partitions, the root itself lv_root and the swap partition lv_swap.

  • Click here for recommended swap size. In my case, I used around 6gb which is the default given from my previous install and even in Fedora 15 it defaulted to the same size.

  • The /boot partition should be left as it in its own physical partition as before. It is required to be separate. If you noticed, it has increased to 500mb as compared to previous Fedora versions where it defaulted to only 200mb.
  • The rest of the partitions (sda1 to sda3) are Windows partitions which unfortunately I am still hesitant to remove just in case I need them although I have reduced it dramatically to around 50gb.
