Change mobo - boot drive format required?

[DwayneElizondo]

Hi, in the quest for a stable 5.0 ghz overclock on my 7700k I've fried my mobo ( oh joy oh joy).

Now, having to change mobo I also decided to upgrade a few thing, and also change form factor, moving from atx to itx - I've read on forums and alike that a new clean install of OS and apps would be preferable in case of a mobo change, but I my situation, with an "orizontal" change, going from a z270E to a z270I asus (Same brand, same chipset), is it really necessary? 'Cause my boot drive is a 500gb m.2 which is almost full of stuff, and reinstalling everything wuold be a real hassle. 

Win10 was an oem copy, so I'll probably have to buy another key, but other than that I don't really foresee any problem...

thanks

See if it boots. Last time I switched a Gigabyte board to another Gigabyte board and re-assembled it, it booted to the desktop no problem.

 

I then of course did a chkdsk and SFC scannow just in case

I recently switched from and old Legacy based Mobo to a "new" legacy-uefi based Mobo and it all worked well without any reformatting. Ofc there was a "getting devices ready" when I first booted the system but it all worked.

Yes good point. Make sure to note if your BIOS on your original motherboard is in EUFI or CSM/Legacy. Then be sure to set the new BIOS of the new mobo the same or you will encounter issues. Good luck!
