Desktop PC: Can I Have Same OS on 2 Different Drives?

[5er driver]

At the moment my PC has only one OS installed, Vista 64 Home Premium on an HDD. I've never had or used a PC with a dual boot configuration. I'm adding an SSD soon and want to put a fresh install of the OS onto it and use it as the boot drive it instead of the current OS on the HDD. The reason I want 2 installs of the same OS on the PC is to make sure the SSD is stable and if not, I could revert back to booting from the HDD and not have to reinstall the OS onto the HDD. I have read horror stories on several forums where SSDs are installed and an OS put onto them and after a few days neither Windows nor bios will recognize the drive, for whatever reason. If that were to happen I could still use the PC by booting from the HDD. Will this configuration work? Can I have the same OS on the PC on 2 different drives and boot from them independently?

Thanks,

The safe thing to do is UPplug the current drive when you install on the SSD. When done, you plug the SATA back and select which drive to boot off of in the BIOS.

Thanks for the info, sounds easy enough for me (fool proof).
