"boot failure insert system disk and press enter" Error After Disk Change (Ssd) & Solutions

- Boot the computer using the Windows 7/8/8.1 installation media.
- On the first screen, press SHIFT+F10 to bring up command prompt.
- Run the following commands at the command prompt.

bootrec /fixmbr

bootrec /fixboot

****
bootrec /rebuildbcd

The bootrec /rebuildbcd command will search for Windows installations not included in the Boot Configuration Data (BCD) and then ask you if you'd like to add one or more to it.



****Note: 

If you receive the error message "Element not found" when you execute the "bootrec /fixboot" orbootrec /rebuildbcd command, then you must first mark boot partition as active with diskpart. Note: If there is a partition labeled "System Reserved", it is the boot partition, if not, the Windows OS partition is the boot partition.

diskpart
select disk 0
list partition
select partition # 
Note: Select the "System Reserved" partition (if you have it) or the Windows OS partition.
active
exit
