Repairing Windows 11 boot selector (Tried multiple methods)

[AssaTM]

Hi all,

I have two separate Windows 11 partitions - however one came from a previous build so I had to rebuild the boot selector, the issue being it doesn't load my second partition when loading Windows and displays the error shown below. However, if I then select F9 to select a different operating system it takes me into the BIOS partition selector and I can boot into either version of Windows absolutely fine.

I have tried multiple methods online with no success so I'm hoping someone has come across this specific issue before and knows how to rectify it.

Thank you

That's not a lot of info to go on, we'd really need to see something like a screenshot of Disk Management to see how your disks/partitions are setup.

If i had to guess I'd say you may have two different partition layouts, one using UEFI and the other using MBR but without seeing the layout of the disks there's no way of knowing.
