I'm adding another SSD to my Alienware 16 Aurora and want to install PikaOS on the new drive. Is it safe to leave the existing Windows SSD installed during the Linux installation, or should I disconnect it first to avoid bootloader or partition problems?

A separate drive makes dual booting fairly straightforward. You can leave Windows attached and select the Linux drive as the installation target, but you need to carefully verify the disk and partition names. If you want the least risky setup, remove or disable the Windows drive while installing Linux, then use the firmware boot selector afterward. Linux can be the default drive, with Windows still available whenever you choose it.
It can work with both drives connected, but disconnecting the Windows SSD during installation is the safer option. That prevents the installer from accidentally placing the Linux bootloader on the Windows drive or modifying the wrong partitions. After PikaOS is installed, reconnect the Windows SSD and use the UEFI boot menu to choose which drive to start. Back up important files first, and make sure you install in UEFI mode.
