Computer Hope

Hi Guys,
so I tried to install  and duel boot  a linux system and Windows 10.  I  have two seperate Hard drives. I have windows on the first one and tried to install UA/Linux distro on the other one. I formatted it before the install. It all seemed to go well until I rebooted it to boot it up.  No chance. I was only able to boot up using the other windows system. I am going to presume that I have not installed some sort of Grub to enable it to boot. But alas, I am only guessing.  I hope the Linux system I installed will be accessable some time as it really look brill.  I was hoping to use the second hard drive because I did not want the Linux system interfering with my  Windows MBR. Hope that makes a bit of sense.  Any advice would be appreciated.

All the best.
