Sorry if I don't provide enough information, it's just that I'm not very savvy with these things. I tried to install elementary OS 6 Odin on a separate HDD while having a Windows 10 installation on my main SSD hoping to be able to dual-boot between them. Now, however, I am unable to boot up Windows 10. GRUB only shows Elementary, Advanced Settings and Advanced UEFI Settings or something like that. And if I try to boot up Windows by booting directly from the SSD, I get an error message stating that the device is unaccessible.

I think it's an error with the boot partitions but I've no idea how to solve it. I'm very worried about this as my Windows 10 installation is very important. How can I get it back?

Thanks a lot in advance!
