    Hello savy118, welcome to Seven Forums!



    No you do not have to 'remove' the current Windows 7 install first, but you should at least use the installer to format the partition during the new installation, look at step #7 in this tutorial at the link below.

    How to Do a Clean Installation with Windows 7


    If you really want the best space to reinstall Windows 7 to, use Option Three in this tutorial to do a partition-specific wipe (secure erase) to the partition first, then do the clean install to the same partition with a format.

    I had Windows 7 x32 and Windows 7 x64 dual boot on my computer. Due to installing the wrong version of Windows 7 x64, I had to reinstall it again from scratch. I reinstalled x64 over the x64 partition and the boot loader menu was still intact after the reinstall. The only difference was it changed the description name from what I set it as to the default when a new OS is installed.

    FYI - If you install two Windows 7's OS's, x64 and x32 - both will show up with the same name in the Boot Manager. You can easily change this in Command Line prompt as an Administrator. Just type;
    Code:
    Bcdedit /set {current} description "Windows 7 x64"
    If you want to change another installation type, just type
    Code:
    bcdedit
    and find the identifier of the other OS name you want to change and {current} to {IdentiferNumber}. E.G.
    Code:
    bcdedit /set {12312-13212-123213-1231231} description "Windows 7 Enterprise"
