    Question about Dual Booting Win 7 & 8 on Notebook

    My notebook that I bought a year ago came with Windows 7 HP. I spent an additional $79 for a Windows Anytime Upgrade key to Pro, so I'm not going to give up Win 7.

    A couple of questions on the upgrade promo (though I'm doing a clean install of 8 Pro). First, does the 100MB System Partition need to be enlarged to 350MB for BitLocker To Go work? Secondly, what does MS consider an "underlying" license? I suppose I could install 7 Ultimate (a TechNet one) beside my OEM one (or furnish the media or COA if needed), it's supposed to be Retail media & license, just no sharing, per the TechNet membership rules, to meet the need for this. Or can I?

    I haven't installed 8 RP on it yet, because I want to know about the System Partition (the 100 or 350MB) issue first.

    Any suggestions will be appreciated.

    Cat,
    The one thing that i do know about dual booting any OS's...Make sure that you make an entire "Full OS Image" and save it off your PC.. When things go wrong ...and they will you'll be glad that you did. Regards Fred

    PS: One other thing ... Keep your main OS ( 7 Pro ) Disk 0 partition 1

    Thanks for your answer, Just Plain Fred.

    When you state "Disk 0 partition 1", does this mean to do away with the 100MB System partition? It probably doesn't mean anything as far as the question, but I have a 128GB M4 SSD, just in case it does.

    And I always keep a system image, usually the 1st one, & the last one, created just before checking for updates on Update Tuesday. Yes, you're correct, things do go wrong, as one who is constantly playing with new software & moving things around (not on my notebook), I usually need one of my images every month.

    Cat,
    Hello... If it's there and you delete it you will "messup" your Partition Table...If your starting from scratch and format and partition before installing "7"..it will get gone ... Not sure what would happen if your Format and Partition and reinstall "7" to the first partition ...If it would try to recreate it again...But that's why you have the "Image" Regards Fred

    PS: It's not there on either of my "7" OS's 32 or 64

    OK, I found it, in System Information. Windows 7 is installed in Disk #0, Partition #1. I was also able to verify that my partitions were aligned (dividable by 4096 to any whole number, w/o a decimal). This is critical for proper SSD performance.

    The number provided in Partition Starting Offset for each partition is the one needed to determine this. Many calculators (especially pocket or cell phone ones) won't work this high of a number, if so, use an online calculator. Here's one that works well.

    So the will the present 100MB System Partition work for the purpose of BitLocker To Go on Win 8 RP?

    EDIT: I wished that I had ran across this trick earlier, if I had, the 100MB partition wouldn't even be there. In the past, I've removed these system partitions, then used the Win 7 install disk to repair the OS to run. Here are the tutorials as to how to install 7 w/o creating the 100MB System Partition.
