I have Fedora and Windows installed in the same drive in my laptop. The drive has 512GB and it’s divided so that each OS has 256GB. Fedora’s partition is encrypted using the option it shows in its installer.

Problem is I’m running out of space. I’m considering getting a 1TB drive on which I would move Fedora and then giving Windows the other drive, so on the whole the laptop would run Windows on the 512GB drive and Fedora on the 1TB one. I’ve already read lots of forums but am still unsure on how to do this without losing any data and messing with Grub (I’ve had some bad experiences previously). So any help would be appreciated.
