Windows 10: Copied SSD Will Not Boot

I have 2 SSD's, one of which I installed Windows 10 on. I copied everything from the Win10 SSD to the other one. It is an exact copy, all of the partitions are the same and everything. However, the other SSD will not boot. It always gives the message about inserting the boot drive. It does this no matter how/where the new SSD is plugged in. Having just the new one, or having both the old and new ones, no matter what, it will not boot from the new one. Booting from the old one works just fine though.

Is there a way to fix this? Since both the SSD's are exactly the same, I don't understand what could be going wrong.

It should be noted that there was another thread that described this problem, but all the answers involved a boot disk. I don't even have a disk drive, let alone a boot disk.

Windows 10 Clean Install Not Starting

Have now tried: Connected the SSD, booted into UBUNTU from pendrive, ensured the SSD is bootable, copied Windows 10 boot files to the SSD. Then close and boot from the SSD. Result is same as before - displays the blue windows logo but doesn't start the
install.

 

How to add SSD as boot disk on new Dell XPS 8700 with Windows 10?

"I copied Windows 10 to the SSD. I then installed it internally in one of the empty drive bays. Windows 10 file manager recognized the drive and I was able to see that "Windows was indeed copied on it."
"

Hello JimPta

The win 10 ISO copy to the SSD or installed??

"I connected the new SSD to the new Dell 8700 via USB."

Is the drive detect as USB or sata/ide??

The newer Pcs have a one time boot priority option on bios boot. F9 or F12 during the bios start screen.

There is a big difference between copying all the files from one drive to another, and cloning the drive, or making an image of one drive to another. Chances are not everything was copied. What you need to do is get up and running with the old drive. then you need to make a rescue disk. You can get one here Code: https://onedrive.live.com/redir?res...hkey=!AJSRBNQM1i3ilPk&ithint=file,ISO[/quote] This is from this forum. Anyway you should be able to make a bootable USB stick. Boot into that, into a command prompt with your NONBOOTING DRIVE installed. Once you are at command prompt, find letter of drive windows is on. It might not be listed as C. If it is C drive, in the command prompt type bcdboot c:\Windows --That should do the trick. Good Luck

 

And, for future use, one can purchase an in-expensive BluRay player/cd-dvd reader/writer external device. Make restorable OS partition and data partition backups when possible, after the initial set up dust settles [I mean using an external hard-drive or two, and Macrium Reflect, Acronis True Image, or something similar, free or pay-for].
