This is my solution for the error I got when install wrong driver or maybe caused by the windows upgrade.
The solution were combined few of other's solutions I refer from the net.
credits to all of them.
First I just follow the instruction like on this video but not works for me. I notice I got an error access denied when I try to input bootrec /fixboot . I think this solution might correct if we don't get this error.
If you got same like me then skip this video.
The solution is to follow just like in this link.
Then if the error still appear check boot manager on Bios setting whether it is the correct disk or not at the first boot drive. Done.
But befor following the solution from the link. First, check if your disk already have the EFI partition.
For my case I still can access my Windows 10 operating system after exit
BIOS screen from the error screen and I dint have any EFI partition my disk. Then I follow the video. before the solution on the link.
refer this video on how to create EFI partition ->
This is how to make partition using Diskpart. please refer this video.
In case you can't access your OS I think the comand for diskpart can be used on the comand line interface at the recovery option.
Thanks.
