When installing Windows 8 I got this error message:

Windows cannot be installed to this hard disk space. 
Windows must be installed to a partition formatted as NTFS.  

Windows cannot be installed to this hard disk space. 
The partition is of an unrecognized type.

I know I got this because I've got Ubuntu on it, but I really want to be sure before I mess up my computer. Do I need to format partition 2 or do I need to do something else? These are the partitions I have:

Do you have any data left on your hard drive? If so, then be absolutely sure to create a backup!

  1. Delete that partition

    That's the only option you have, according to your screenshot.

  2. Create a new partition

    A new list item called "Unallocated space" should appear. Click "New" and create a new partition. You should choose about 25 GB minimum space.

  3. Format

    Select the created partition and hit "Format".
    As far as I can remember, this step is not absolutely necessary since Windows will automatically perform it if you haven't done yourself.

Won't I lose any partitions? – sofboy Nov 27 '13 at 20:55
@sofboy You will lose partition #2. On which partition is Ubuntu installed? Do you want to overwrite the whole hard disk? – ComFreek Nov 27 '13 at 21:10
Yes,but the size of mine memory(923GB) will stay?:p – sofboy Nov 27 '13 at 21:12
@sofboy The disk space of your hard drive will never change. If you directly follow my steps, the partition size will stay the same (freeing 923 GB --> unallocated state --> creating new parition 923 GB). – ComFreek Nov 27 '13 at 21:51
