Can't format my SSD til NTTS

Hi,
I can't format my SSD drive to NTTS. The SSD drive did run Linus 14.04 first but then I decided to download windows 8.1 64-bit. I clicked on the format button on the SSD, but I got an error saying "the partition have to be formated to NTTS" And when I tried to go back to linux for trying to format the SSD, a got another error saying I didn't have any OS on my SSD drive (must have deleted it when I formated it). So I connected the SSD drive to my desktop computer but in the disk management the option format isn't clickable. Please help :)

The 4 first drive on the pciture (disk1) are thoose I need to format.

You should be able to just right click those partitions and delete. This will turn them into Unallocated Space. When you delete all, again right click on Unallocated Space and create new Simple Volume. Follow the instructions to finish.

However, I am not sure if you need the EFI partition. So try this first:
- Shutdown and unplug power to the 2nd HDD (Disk 1- 224 GB one).
- If Windows boots fine, then attach it back and delete EFI too.
- If it can't boot, don't delete the EFI, only delete the other 3

Thank you so much, used a lot of time trying to figure this out, so I can't say how thankful I am :)
