New motherboard, so will I have to fresh install my multi-boot rig?

I just purchased a new MB, a MSI Z77A-GD55 and am upgrading from a B75 Gigabyte board. I will be swapping onto it my i7-3770k, my MSI GTX 760 OC TwinFrozr and my SSD which is currently set up to dual boot either Windows 7 or Windows 8. Prior to this I had another motherboard (Gigabyte Z77A-UD3H) that didn't work so I went back to my B75, I then "upgraded to W8" and after not liking it, decided to do a fresh install and partition for multi-boot of both W7 and W8. Now my rig is set up just how I want with both OS's in their own respective drive path. Once I open the case up and pull this thing apart, then put it back together on the new MB, what am I going to do for the OS SSD? I am certain it shouldn't work on the new MB the same but is there anything I can do in the BIOS so I don't have to fresh install both operating systems or is a fresh install the only way to go? I don't want glitchy operating so if the second way isn't as good as the first just give it to me straight :) As a side note how much space should each partition have for each OS? Right now I have 70GB for Windows 7 which I have my games installed on and 40GB for Windows 8 which I don't use too much unless I am syncing with my new Windows 8 phone (yay). I love this combo by the way and I am thoroughly enjoying the awesome SNES emulator for W8 and W8P. Another question, I have a decent air cooler for my CPU (EVGA Superclock). What is a good overclock for the 3770k on air? is 4.2 a good OC or should I go higher? Thank you all who read and reply, your help is invaluable. FYI I have 20GB free on the W8 partition and 30GB free on the W7 partition as well as a separate 1TB HDD for my media files which is shared across both libraries and OS. Thanks again.

    Yes unfortunately you will need to reinstall the operating systems. There is probably a way to get around it but it's probably easier to save the time and headache with a fresh install.

    4.2 Sounds like a good over clock, it's enough to give it that bump without having to constantly monitor temperatures and stability issues.

    You're going from an Intel chipset to another Intel chipset. Just make sure the new motherboard's Intel SATA controller is configured the same (AHCI or RAID) and then try it. You have absolutely nothing to lose. You'll probably have to upgrade the drivers, but it should work.
