How to install POP OS dual boot with windows on separate drive without erasing data of other drive?

I have windows 11 on 250gb ssd and a 500gb empty hard drive. I want to install POP!os on one of the partition of this Hard drive and let the windows be on the ssd. So while partitioning space to install linux if I select D drive from my HardDisk and does further partitioning there for linux os then we will get Erase and install option. **Now does this option erase all my data from the ssd also? or only from the drive I selected.** If it does delete then what is the other safer option to not delete the ssd data? Also is this way of partitioning correct or Am I doing anything wrong?
