Hello guys,

First of all, I am using windows 8.1. Everytime I attempt to reset it the error "REQUIRED DRIVE PARTITION IS MISSING" always appears. I have googled this problem and I've found the suggestion (using bootrec):
In the command prompt, type

1. bootrec /fixmbr

2. bootrec /fixboot

3. bootrec /rebuildbcd

Now,  bootrec /rebuildbcd command always results in 0 total...

So (4) attrib C:\Boot\BCD -h -r -s

However, I always get the response "C:\Boot\BCD FILE NOT FOUND"

Can anyone help me please? Thanks so much!

Hi Blessed,

Have you got an installation media ?

If we haven`t got one ,we can made one referring to the following link :
Create installation media for Windows 8.1
http://windows.microsoft.com/en-HK/windows-8/create-reset-refresh-media

We can boot from the installation media and then choose the repair mode during the  install now screen .And choose the Startup repair option in the Windows Repair Environment .

If the automatic repair will not work ,choose the command line mode and take the following steps to have a check.
Type diskpart
Type select disk 0
Type list partition
then note the partition number where you installed windows 8.1.
Type select partition X   (X is the partition number where Windows is installed)
type active
type exit
type bcdboot c:\windows  (if C is your windows partition)

Here is a link for reference of this method (Juke Chou`s answer):
BCDboot "Failure when attempting to copy boot files" (This method should also be applied to Windows 8.1 )
