Hey everyone! I started my journey into Linux a couple of days ago and I've been planning to dual boot Windows 11 and Kubuntu. I've got my USB set up with Kubuntu 25.04, and I just bought a new 1TB Kingston Fury SSD for the installation. Here are my planned steps: 1) Remove the old SSD with Windows, 2) Install the new SSD, 3) Plug in the bootable USB, 4) Boot from the USB via the Boot Menu, 5) Install Kubuntu on the new SSD, 6) Reconnect the Windows SSD, and 7) Choose which OS to boot from the menu each time. My questions are: what should I do about the EFI partition so that Linux won't detect Windows and vice versa? Am I missing any steps? Any extra tips?

Just a heads up, Linux won't specifically detect Windows if the SSD is removed during installation, but you might still need to regenerate the GRUB config later. If you choose the bootloader from your BIOS, that will work too. It's fantastic that you’re diving into this! If you do have any questions later, you can always reach out.
Yeah, the separate drive setup you have is smart! Setting Linux as the boot priority will allow you to access the GRUB menu, letting you choose between Linux and Windows easily. Since you'll disconnect the Windows SSD during the install, you shouldn't run into any configuration issues between the two. Regarding customization, definitely, you can personalize your GRUB menu to make it look cooler! There are lots of guides online.
Your steps look great! Linux will indeed detect Windows, but that's actually helpful for dual booting. Just be careful not to mess with the Windows partitions during the installation. To avoid Windows messing with the Linux bootloader, having separate drives helps a lot. Once you plug the Windows SSD back in, you can adjust the boot priorities in your BIOS, selecting Linux as the default to get the GRUB menu where you can choose to boot either OS. You've got this! Good luck and enjoy your new setup!
