I was trying to set up a dual boot with CatchyOS and Windows, but I accidentally messed up my Windows boot manager. I had Windows installed on one drive and planned to install CatchyOS on another, but I think I deleted the boot manager somehow. GRUB isn't recognizing my Windows installation at all, and now I can't boot into Windows. Is there anything I can do to recover my Windows installation?

I ran into the same problem and ended up creating a USB installer for Windows and that did the trick! Just followed some online instructions to get it set up again. Sometimes the simplest solutions work, right?
I doubt you actually deleted the Windows bootloader; it might just be a GRUB configuration issue. Try selecting your Windows SSD in BIOS and see if you can boot directly from there. If that doesn’t work, installing `os-prober` and running `grub-mkconfig` after mounting the Windows partition could help. Here's a useful link for more details: [Detecting other operating systems](https://wiki.archlinux.org/title/GRUB#Detecting_other_operating_systems).
If your Windows drive still exists and hasn't been overwritten, you might be in luck! Check out using `os-prober` with GRUB to see if you can recover the boot option for Windows. It should help you detect the installation again.
Tried that already, but I still can't boot into Windows. It’s like it’s gone!
