Sometimes we encounter problems in booting our windows system up. Even after trying to do automatic startup repairs, the windows fail to boot. It gets stuck in a continuous failed boot loop. This may be because for some reason the windows boot manager is misfunctioning. In this video, we will completely rebuild the startup partition and boot files for windows. For this, we will require Windows installation media. It can be created using an app called Rufus or Windows media creation tool from the Microsoft website. The process is simple and a guide to create windows installation media is covered in this video: https://www.youtube.com/watch?v=Cdydlz5TiA0 In this video, we have also covered the resolution to the Access denied message that we may receive while using bootrec fixboot command. The list commands used in this video are: diskpart list disk select disk 0 list partition select partition 1 format list vol select vol 2 assign letter=g: exit bootsect /nt60 all /force bcdboot c:\windows /s g: /f all bootrec /fixmbr bootrec /fixboot bootsect /nt60 sys bootrec /rebuildbcd exit Note: Please use the disk, partition, and volume number as shown in your system. Also, use your systems path to the windows folder while using bcdboot command. I hope this video helps in repairing your system's boot partition. Thank you.
