    Boot Change Help


    I've searched the forum and haven't seen anything like this.
    I have a win 8 /win 7 system. the win 8 is the default boot os.
    Unfortunately I installed win 8 with the win 7 drive in the system and the computer needs that win 7 drive in order to boot.

    I've tried a bunch of things to get the win 8 drive fully setup to boot alone but can't seem to get it right.
    I tried just booting up with the win 8 drive only in the computer and then run bootrec. I tried all the options in bootrec and all are successful except the important one. When I tell it to add the c: drive to the boot menu I get...
    "The requested system device cannot be found'.

    My goal is to get the system to boot to windows 8 all by itself and then add the drives I want after that.

    Here's a copy of my bcdedit command and thanks for any help you can provide...

    Partition K: is my win 7 drive and C: is Win 8

    Welcome to EightForums.

    Try doing a Automatic Repair from the DVD.

    Note: You may need to do startup repair 3 to 4 times.

    Tried that and did it 3 times as I read somewhere that it only solves 1 problem at a time and might need to do it 3 times. But it just gets to the point where it says it can't repair.
    A side question - If there is only 1 drive in the computer it doesn't matter which port on the motherboard u plug it into right? Also I left the data cables plugged in while trying this and just disconnected the power to those drives. That doesn't matter does it? Thanks

    I still get the system device not found.
    I noticed in the disk management console that the win7 drive is marked as the 'system' and 'active' disk (MBR)
    The win 8 is GPT and marked as...
    (Boot, Page File, Crash Dump and Primary Partition.

    I think I somehow need to get the bcd store on the win 8 drive. But I'm sure just copying the bcd folder over and trying to rebuild from there won't do either probably. I have to figure out how to make that disk the 'System' disk.
    Can bcedit assign a value so that bootrec /rebuild would see the a "System Device" that it is now not recognized when that's the only drive hooked up?
    I know there has to be a way to do this.

    You can not dual boot with One OS installed in uEFI mode & one OS installed in Legacy mode.

    I beg to differ but i'm doing that right now. Win 8 on 2 different drives (1 mbr and 1 gpt) and win 7.
    All will boot fine but they r doing it initially from the win 7 drive that I want to get rid of.

    Oh and I tried using easybcd's 'change boot drive' but it fails saying it needs a primary partition on my C: drive (GPT)
    The C: disk shows the partitions correctly in the management console and the primary partition is listed. The drive shows as Boot, PageFile, Crash Dump and Primary Partition.
    Unfortunately the disk marked "System" is the K: drive.

    You not dual booting, you are initially booting each OS.

    Below is a screenshot of Windows 8 & Windows 7 dual booting in uEFI mode, & Win XP initially booting in Legacy mode.

    You can only dual if both OS are in the same mode.

    Maybe I misunderstand what dual booting is.
    I thought if you had the option at initial boot to choose whatever system you want to load... i.e win7, win 8, Linux etc. then it was a multi boot system.

    At any rate I still have my problem of trying to have ONLY my win 8 ssd in the system and get it to boot.

    As Disk 0, 1, & 2 are marked ACTIVE, I am taking that as three OS's installed, there can be added to the boot menu with EasyBCD,
    as there are installed in Legacy Mode.

    The OS on Disk 5, can not be added, as installed in uEFI mode.
