I previously installed Linux on my system without a USB by creating a bootable partition in Windows. Unfortunately, I ran into some issues and now I'm left with only Linux (thankfully, I forgot to remove that bootable Linux installer partition). Right now, I have Arch Linux with KDE and I'd love to restore Windows onto the other partitions that are damaged. Can anyone guide me on how to create a bootable partition for the Windows installer? I was hoping it would be as simple as it used to be in Windows, but I realize that might be asking a lot. Any help would be greatly appreciated! Thanks!

I don’t think you really need to try dual-booting. Honestly, it usually leads to more frustration than it's worth. I’d say backup your important files, choose one OS, and get comfortable with it. Trying to juggle both is a tough road!
I recommend doing a fresh install after backing up your data. But if you want to recover your Windows, here’s a method that might help. First, you’ll need an external USB drive (at least 8GB). From your Linux system, identify the disk that has the corrupt Windows EFI partition. Download the Windows 11 ISO from the official site. You can use Ventoy to create a bootable USB with the ISO. Once you boot into the USB installer, press Shift + F10 to open the command prompt. Use the DiskPart tool to create and repair the EFI partition—make sure to run the commands carefully to restore those boot files. Good luck!
Sounds like a solid plan! Just make sure to follow all the steps closely, especially when handling partitions, as it can be tricky.
Honestly, I went through something similar and found that sometimes it's just better to wipe everything and start fresh with Windows. The Windows partition manager is pretty user-friendly, so I’d advise going that route if you can. Just back up everything you want to keep first!

I get your point, but sometimes dual-booting is necessary for particular tasks. It really depends on your needs.
