Grub has overwritten my main hard drive

I installed MX Linux into my ssd to dual boot it with PopOS but I chose the grub option because it said that I can dual boot easily with it. But that one choice doomed my life. my main hard disk has been overwritten by grub and grub now doesn't recognise PopOS as a choice. I have been researching for months while using mx but nothing, absolutely nothing. Tried to edit the grub.cfg file, tried to edit the mx boot options, tried to literally **remove** the ssd and try to force boot the hard drive but it was of no use, nothing I found from here, youtube, mx forums, grub's website, nothing could help. I wanted to install windows as a replacement to the other os on my hard drive but for some reason grub prevented everything. I can provide you any details just please help me I feel like my pc is stuck in this state with no other way to even replace the os'es. I'm literally stuck with MX Linux
