Repair dual boot setup with windows

I have a device on which I previously had a working dual boot setup with Windows and Manjaro. A couple of months ago, I replaced the Manjaro install with Fedora 32. Ever since then, I can’t boot into Windows anymore, despite the fact that the Windows partition is still there. I tried to create a custom grub entry based on this Stackoverflow answer, but that didn’t work either. Is there a way to repair the dual boot setup?


A little more info would be helpful.

What is the machine you are using? brand & model? Laptop? Desktop? 32 bit? 64 bit? What version of windows? Is windows booted from UEFI or legacy BIOS? How was F32 installed? (legacy or UEFI).

Can you boot to fedora then send us the output of “lsblk” and “sudo fdisk -l”

This almost sounds like one system may have been installed legacy mode and the other (newer) one installed UEFI mode. That situation almost never works.

You may, however be able to confirm if windows is still functional by selecting it from the bios boot menu and attempting to boot. If that works then the repair should be relatively simple.
