1. Windows +R
2. Type "cmd"
3. At the prompt type "diskpart"
4. then after the ">" symbol type " list disk"
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
Disk 0 Online 28 GB 1536 KB
Disk 1 Online 233 GB 993 KB
5.Now select the disk which you want to make INACTIVE (For instance if i want to make my Disk 1 as active i.e where the OS is installed and REQUIRED to boot, i need to select the drive which i want to make INACTIVE. In my example DISK 0)
DISKPART> SELECT DISK 0
Disk 0 is now the selected disk.
6. Type "list partition"
DISKPART> list partition
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 28 GB 1024 KB
7. Since there is a single partition on DISK 0, select it by issuing the command "select partition 1"
DISKPART> select partition 1
Partition 1 is now the selected partition.
8.Type "inactive" - this will make disk 0 partition 1 as inactive
=============================
Explanation : This error crops up because you have been in Computer Management > Storage > Disk Management and selected more than 1 drive as ACTIVE together with the one which was already active- the one where your OS was .
Point to remember : THERE SHOULD BE ONLY ONE ACTIVE DRIVE SO YOU CANT SET MORE THAN ONE DRIVE AS ACTIVE
********************************IMPORTANT THING TO DO FIRST ***************************************
Also since you cant get your OS to boot you must specifically select the boot disk from where to boot.
On my PC it was F12-> then i selected "hard disk" from where i had all my drives listed.
From here you must select the drive where your OS was initially installed
Finally run the command 1-8 above the disable the other drives as ACTIVE.

Hope i helped you
