    Can't dual-boot installing inside Win7


    Can't dual-boot installing inside Win7 ...

    I have a second hd in my machine, when I attempt to install to that drive running a mounted iso from inside Win7 I don't get the options to where to install. It asks me what I want to keep, as if it is going to upgrade my os. I don't want that, I want to dual boot. Any clues anyone?

    Thanks in advance.

    Burn a DVD from the .iso and try with that. But if you have 2 HDDs, I would disconnect the other HDD during the install and change the BIOS boot order for OS selection. Is a faster boot.

    You are using the wrong setup.exe. Go to the "sources" folder and use that setup.exe.

    I wish I knew that earlier. I am stuck with two separate partitions which fail to work together.

    Do not install with 2 hdd's present! It will not work! Unplug one, install, shutdown, re insert hdd, then start your pc. and you should be good.
