Win Boot Menu Show/Hide, how?

[nadiadsz]

I have dual boot, but i there is one OS that i barely use, lets say once in a week, but everytime i start the pc its takes more time due to the load of the boot menu so i want to know if there is a way to hide it and show it with a combination of keys or just a key... i google it but i didnt find anything. This exists? 😛

Sorry if the category is wrong, didnt know where to put this 😛
