Grub error: unknown Filesystem with no OS installed

Idk if this fits here but I have a problem. I wanted to install windows 10 as second OS on another hard drive but it didn’t work with manjaro installed, so I just thought it’ll work if I uninstall manjaro. Plot Twist: It didn’t. I am now stuck at a point where I could hypothetically install Manjaro again but not Windows. When I try to run windows from a USB-Stick I get the error “unknown filesystem” even though I wiped both my HDDs and then re-partitioned them to ntfs.

Idk how to explain this because it’s extremely weird. Can someone help?

Just note that this is a Manjaro Forum, therefore it is there for Manjaro Topics. If you have Problems installing Windows 10, then please visit a specialized forum for that. Windows is known to be incompatible for dualboot setups, it only works with tweaks on the cmd when installing as second OS.

If you continue asking for help installing Windows, then this thread will be closed according to the forum rules, since this is explicitly off-topic.
