How to restore grub?

Question

Windows

Hello, I have installed UBUNTU 14.04.3 on the HDD and installed grub on this drive. I also have an OCZ RevoDrive2 x3 on which I installed Windows 10. Everything was installed sort of like in efi mode. How can I dual boot from grub if Ubuntu completely ignores RevoDrive? He sees it as 4 separate disks without FS. Now, when specifying a boot device on the HDD, Win10 is also loaded from Ubuntu.

In general, it was enough to boot from Ubuntu Live and download Boot-repair and run it, and it did everything!)
