I understand your concern. Installing Windows 7 on a system with an existing OS like Windows 10 involves compatibility checks. You can follow official guides or use tools to verify the installation order. If needed, you may need to perform a clean install or use a virtual machine for better control.
Theoretically you receive a list asking which windows to start automatically, but in reality it may not work consistently because the installer chooses where to place the bootloader.
You just access separate storage via your boot settings in BIOS/UEFI. No hassle at all. The steps would be... Unplug your Windows 10 drive completely (and ideally other drives except the Win 7 SSD). Install 7 onto the SSD, complete the drivers and setup. Reconnect the remaining drives. Select the boot device using UEFI/bios. Just remember, Windows 7 doesn’t work well with UEFI mode.
