Windows 10: Easy BCD boot assistance

HP G6 i3 usb2.0 laptop. Came with Win 7 Home on a 5400rpm HD. Got USB 3.0 10 port powered hub.
Installed new Samsung SSD with Win 10 on 1st of three partitions. Win 8.1 and Linux on other partitions. Works Fine.
Need to boot to external 5400rpm HD via USB to run work related proprietary Programs I can't. transfer.
Got boot menu to boot into Win 7 but it crashes as soon as the Windows logo appears. I do not even see a login screen.
I have multi booted for years on many a system but always internal only. This is my first attempt to boot to an external USB HD.
I'm out of ideas. Need help please.

How to clean up BCD entries? Rebuild the BCD?

This is normal that under Recovery Environment, The letters are re-assigned. This is why you have to be careful and select the correct one.
@dictum
Advice: Never use Easy BCD with Windows installed using GPT disk. Use Easy UEFI instead provided you know what you are doing. Easy BCD only works with MBR disk type.
Base on the screen shot above. Your disk 0 is your new Windows and your disk 1 contains the old Windows. Disk 3 contains a 512MB Fat32 partition and I don't know what that is. I suggest you disconnect disk 3 for now before proceeding.

Let rebuild new BCD's for both disk 0, and disk 1. Please follow step by step on the 2 screen shots below. On step 3, write down the drive letter for PM981_New. In the screen shot, My Windows is still assigned to C but it might be different from yours. In step 10, if the drive letter is different than C, then use the letter in step 3.

Do exactly the same for disk 1, this time select disk 1 in step 4 and assign letter V in step 7, Use V and the drive letter for Old Windows in step 10. This will create a new BCD for PM981_Old and you will be able to boot separately from boot menu.

From boot menu, select which one to boot from.
Once booted into Windows. If you wish, you can set up dual boot for Windows old & New. Under This PC, look for the drive letter of the offline Windows and type:
bcdboot X:\Windows where X is the letter of the offline Windows

 

Multi Boot system Easy BCD issue

Ok so here's what has happened. I have a multi boot system. Windows 10 on my M2 hard drive. Then on another SSD I have Windows 10 Creators addition that I use to test updates . Then 1 more SSD that has Windows 7 and Windows 8.1. All were booting fine using Easy BCD until I added Linux on another SSD. I installed Linux with all other drives unplugged except the M2 which is not easily removed. Now Linux Grub boots first with Windows 10 on the boot list.
I'm assuming that Linux installed grub on my M2 Windows 10 installation.
I have tried to repair using Windows installation disk but no result.
How can I get Easy BCD back to be my first option? Then I can add Linux to the boot menu.
Thanks
