Windows 10: Newly installed 2nd internal hard drive causes boot failure

I am running Win 10 64 bit, version 1803.
I have just added a second internal drive to my system. It displays in Admin as Drive E 298.08 Gb, NTFS healthy, page file, active, primary partition, layout simple, type basic).

With the second drive E: installed my boot drive C: only boots intermittenly, but only after removing & reconnecting E: to the motherboard with the system in a live state.
I have spent probably 2 solid continuous hours with microsoft chat support with 3 different techs but none has been able to resolve the issue.
The only off the cuff comments from one of the techs is that the boot drive C: is possibly confused because it believes it is seeing a second operating system on the new drive, whereas it wants to see only a "storage drive".
The techs have tried to configure the drive remotely but unsuccessfully and without telling me what the properties of the new storage? drive should be, so I'm none the wiser how to get it to work.

Any help would be appreciated.

recovering files and transferring them to another internal hard drive

Hi,

To help resolve your concern, kindly follow the steps below:

• Install the 1 TB hard drive.
• Install Windows 10 operating system to the 1 TB hard drive which you added.
• Change the BIOS settings and set first boot option to the newly installed hard drive with working Windows 10 operating system (BIOS settings would differ per manufacturer. Contact your PC manufacturer for assistance on how to do this.)
• Boot to Windows 10 of newly installed hard drive. Windows 10 should see the other drive.
• Copy and paste the important files from other drive to the new one.
• Format the other drive (as needed).

You may check those files you wanted to moved under C:/Users/username.

Let us know how it goes.

 

Error adding a 2nd internal hard drive

I believe the 2nd drive was used for Linux, but it is not in the boot order list in bios. The only drive in the boot order is the correct drive, but it still tries to load the wrong 1.

 

Removal of non-system hard disks causes boot failure.

I have windows 10 pro installed on a Crucial 500GB SSD.

I also have 2 2TB Seagate Internal Hard Disks installed.

I recently purchased 2 3TB Seagate External Hard Disks, so that I can keep my data portable and decided to remove the internals altogether.

Although I installed windows 10 to the SSD, when I remove the two HDDs and try to restart, it shows a boot failure.

As if my system is somehow dependent on one or both of these drives that have no system data on them.
