I also suspected that maybe my Windows install was corrupt but I ran sfc and it did not find anything wrong. f I reformat my System Partition to FAT32 then run this command:ĭo you think that will work? Also currently my Windows Partition is the only bootable partition (I can change the boot flags on E: if needed)Ĭ: - Windows Partition - NTFS My disk is formatted as a GPT scheme but I created a Hybrid MBR gdisk so that Windows thinks it is installed on an MBR partition.
It also may have something to do with the Hybrid MBR setup I mentioned earlier. Wondering if the tool is not creating a proper BCD for BIOS booting? I know Windows 10 supports BIOS booting but I am It is leading me to strongly suspect that it is an issue with booting Windows 10 in BIOS mode. I tried running the bcdedit command that you gave and it still boots to that black screen with a cmd cursor. I really appreciate that you are helping me with this issue. That's what I was trying to research there and why I tried to find a page which could explain the differenceīetween bootsect and the equivalent functionality in bootrec. I was just indicating my surprise that DOCS doesn't seem to mention bootrec. It also still comes with the Windows 10 installer. It seems that several sources online still recommend bootrec to repair Windows 10 boot. We probably need to do some more searching, this time involving GRUB or just non-Windows OS in general. I imagine that bootrec /SCANOS might miss your other OS but maybe not. Repairing a multi-boot legacy scenario? Another uncertainty would concern your non-Windows OS. One interpretation would be that it is needed for I thought the "summary" page I found for you mentioned bootsect as an auxiliary tool but I don't even understand why it would be needed. Any ideas?Īlso, if someone could explain which of the above commands actually installs the Windows bootloader back to the NTFS partition boot sector?ĭo I restore the boot sector of my NTFS partition and boot Windows 10 via Legacy BIOS Mode? I suspect the solution may involve reformatting my EFI System Partition to FAT32, and then creating the following Hybrid MBR table:Īnd then hopefully the "bootreq /fixboot Access is Denied" error will go away. My question is, how do I restore the boot sector of my NTFS partition and boot Windows 10 via Legacy BIOS Mode?

Windows is on Partition 4 below (It still says Windows 7 because I upgraded from Windows 7).
