Windows 10: Unlock system drive

I am installing Win 10 from Dell disk to replace Win 7. Says system drive is locked. How do I unlock it and proceed with Win 10 installation?

unlock hard drive


I just installed w10 and I love it!!!!!!!!!!!! I have a dell laptop with a ssd and it works fine. the problem is my second harddrive which is connected a usb and it has all my data on it, except it is locked and cannot edit a file and save the file. We will call that #2, #1 works fine, I can edit and save, #2 I can view but no edit and save. I use photoshop and when I go to save it states that the file is locked. #2 is partitioned into 3 drives and all drives act the same. everything worked on win 7 in the same configuration.
So with my whiz bang mentality I say the drive is locked. But I do not know how to unlock it !!! can anybody help me!!!
I am a old senior teckky and things have to be laid out step by step. Is there a program I can download to unlock the HD,??? or do I have to do it the old fashion way, step by step

TIA

Enable Bitlocker auto-unlock without system drive encryption

1. turn off bitlocker on the drive you want to auto-unlock
   
2. mount this drive as a removable drive
   i.e plug it into a usb attached drive unit such as StarTech or many others
   
3. boot the system and bitlock the drive and turn on auto-unlock
   
4. shutdown the system
   
5. mount the drive as a permanent drive
   
6. reboot the system and the drive will auto-unlock because windows now thinks
   that it is a removable drive
