Windows 10: Boot manager on wrong drive

I just replaced the HDD in this desktop PC with an ssd, but both drives were connected when I installed windows on the SSD. For some idiotic reason it requires BOTH drives to boot to the SSD. Is there any way to fix this without having to reinstall windows all over again?

Windows 7 booting off wrong drive?!?!?

Please move if this is in the wrong place.

I have two hard drives, a 1.5TB drive, and a 160GB drive. Windows is installed on the 1.5TB drive, as are all my files and programs. The 160GB drive has a bunch of old files, and apparently the bootmgr and boot folder. Nothing else is on the 160GB drive, other than media files etc.

If I remove the 160GB drive from the machine, windows refuses to boot, plug it back in, it works fine. The setup with two hard drives I have now is temporary, as the 160GB drive will go into another machine.

My question is, can someone give me a step by step on how to make windows force to boot off the 1.5TB drive, ignoring the 160GB drive in the boot process completely?
I don't know how to do this in Windows 7, on XP I would just run the /fixmbr command and its related ones.

Any help would be appreciated.

Note: I would really really rather not have to wipe and reinstall, I know it can be done without one as I've had this issue with XP before.

 

Booting from wrong hard drive

Hi,

Thank you for posting your query on Microsoft Community.

I would like to know some information.

• 
  Since how long are you facing this issue?
  
• 
  Did it ever booted with Windows 10?
  
• 
  Have you made any changes to your computer settings prior to this issue?
  

I would request you to please provide us the screen shot of Disk management whether it shows the drive or not.

Refer to the link:

You may try the steps.

I would suggest you to try to check for the status of the drive in the device manager.

1. Press Windows Key + R Key.

2. Then type “devmgmt.msc” without the quotes and hit on
Enter Key.

3. Expand Disk Drive. If you are able to find the driver for the external drive.

6. Then again right click on the driver and click on Properties.

7. Check the device status of the disk.



Hope this information helps. Please let us know if you need any other assistance with Windows in future. We will be happy to assist you.

There could be some system conflict triggered after the said changes. To help you with your concern, we suggest that you perform a clean boot. A
