Windows 10 GPT partition keeps getting MBR corrupted after restart
Recently my friend laptop got problem with the master boot record & keep showing that "no bootable devices can be found".
I though it's only a MBR problem but then I fixed the MBR & rebuildBCD with following commands
bootrect /fixmbrbootrect /rebuildbcd
bootrect /fixboot-> Output of this one giving "Access Denied"
I then can boot again into the windows. However, after restarting the problem comes up again.
I also try to delete all partitions and create all drives all over again, including formatting System Reserved drive.
After installing windows one more time, I got several successful reboot & then it comes up again. At this time I have no clues. (The system diagnosis from Dell showing green check on Hard Drive)
- ACHI enabled
- UEFI enabled
- Partition is GPT

But UEFI systems do not use a MBR.
