Os installed on SSD and replacing HDD

[Ariel750]

I have 1 SSD and 1 HDD. My OS is installed in SSD and i wanna replace my HDD (since its only 5400rpm) will replacing my HDD remove the OS still?

This maybe a dumb question but i still wanna make sure.

Test it.

Power off.
Disconnect the HDD.
Power up.
Does it boot properly?

(It doesn't remove the OS, but in some cases, removal of the secondary drive does impact the boot process)
