I've done this a lot of times and it worked normally but this time there's a little difference:
- I got by normal windows 10 and ubuntu 15.04 dual booting with grub and all.
- I installed CentOS 7 instead of Ubuntu and still everything was fine.
- Finally installed Ubuntu 15.04 instead of CentOS 7 and re-activated grub, but I don't get the windows 10 bootloader anymore.

Finally the Ubuntu Menu is still showing 3 Hard Disks: LRS_ESP (opens directories after click) , Windows8_OS & Backup (which are 2 other partitions but they don't function on click anymore)
What could the problem possibly be? Because I don't think the windows partitions got formatted in the middle of this.
