Reinstall Yosemite AGAIN but clean with existing Bootcamp

Hi I have a very simple question to which I can't seem to find a conclusive answer.

My setup is as follows:

Mavericks -> Yosemite upgraded OK

Installed boot camp OK

But system is slow still so I want to do a FRESH install of Yosemite instead. I intend to do this by creating a bootable thumb drive and erasing the current Yosemite partition. My question is this

Will this mess up my Win 7 bootcamp partition or stop the dual booting process in anyway ?

Many Thanks

Mark

iMac, OS X Yosemite (10.10.2), iMac 27" 2010 4GB RAM

No it won't. I've installed Yosemite from "scratch" on an external harddrive. Then afterwards I formatted the internal Mac-partition (do have a bootcamp partition with Windows 7 installed too) and used Carbon Copy Cloner to install Yosemite on the internal drive. No problems. But check the bootcamp preference pane to secure the right performance of Windows 7 afterwards. You can use Winclone to make a clone of the Windows 7 partition as a security before formatting the Mac partition. Please Google on Winclone eventually.

Well I erased the the OS X partition and did a clean install of Yosemite and the the dual booting still works. Note I did not change the partition size at all I kept the same partition scheme.

Next question tho if I just copy back the user accounts ONLY not Applications etc will this bring over any unwanted junk i.e. sys files etc that may have caused the slow down in the first place. ? As far as I know it just copies mail, iTunes and iPhoto files etc plus documents that I created with other apps which I intend to reinstall separately.

Thanks

Sorry, but you have to search elsewhere concerning user accounts. Can't help you. Too specific for me.

So I just used migration assistant to bring back just the accounts NOT applications and things do seem to be faster so I guess it will do for now. Not sure if manually adding stuff back i.e. creating the account from scratch and just adding the user folders back would make it any faster. But at least the OS system files are fresh which seems to help.

Thanks for the response.
