Repair Windows BCD error

So today I start up my laptop i get a blue screen and see error message like this Z:\EFI\Microsoft\boot\BCD missing file. I was a ticked due to I just reformatted the computer. So I did some searching and I found a fix.
diskpart (opens Disk Partitioning tool)
select disk 0
list volume (please note the number of the volume that has no drive letter assigned and has FAT32 listed in Fs column)
select volume
assign letter=Z: (gives drive letter Z: to EFI System Partition)
exit (closes Disk Partitioning tool)
cd /d Z:\EFI\Microsoft\Boot\ (changes current folder in Command Prompt window)
attrib Z:\EFI\Microsoft\Boot\BCD -h -r -s (removes hidden, read-only and system attributes from BCD folder)
ren Z:\EFI\Microsoft\Boot\BCD BCD.old (renames BCD folder to BCD.old)
bootrec /rebuildbcd (retries the rebuild)

AFter this press the button your computer and reboot it.
