[ubuntu] Will Installing Ubuntu over my Mint partition ruin my dual boot Windows 7

view story

http://ubuntuforums.org – I dual boot Windows 7, and Linux Mint. I have a backup I desperately need to restore that I created in Ubuntu using Deja Dup. I cannot get Deja Dup to launch in Mint so I am planning on possibly installing Ubuntu in the partition that I currently have Mint installed on, but I am worried that installing a Linux flavor after having Windows 7 already installed will cause Windows to no longer run.
