On my computer I have my main hard drive (WD 500 GB) which is drive C:\ with windows 10 preview. I also have a backup disk installed. Today I added another hard disk with the intention of making the backup disk and the new disk dynamic. After installing the new disk, I went to disk management and (supposedly) did this. Windows disk management said that I had successfully created dynamic disks, however, the the computer still saw two separate disks.
Now, I went back to disk management and changed the new disk back to basic disk, but it would not let me on the backup disk. attempting to delete the volume on the backup disk would not work either.
I went to MiniTool partition magic and attempted to write zeros to the back up disk and partition magic warned me that if I did this, I would not be able to restart my computer
Then I found out that if I unplugged the backup disk I cannot boot my computer, even if I go into bios and made sure that the preferred boot disk is the 500 gb hard disk. Can someone explain to me why this is and what I did wrong when attempting to create dynamic disk?
