Boot Change Help

  1. #21


    ok, rather than spend 50 bucks to find out whether it will do it or not I think the following might work. I'll be getting around to it tomorrow sometime. And I know I could have just done a re-install or a refresh or a blah blah by now but now i'm doing this more to learn about uefi and gpt. also, it's still a pain to get a machine back 'just right' like u had it if you can't just restore a current image.

    Anyway, I'm thinking this...
    1. Backup just win 8 PARTITION
    2. Disconnect drives totally except for new ssd
    3. Install windows 8 on new ssd with uefi turned on in bios
    4. reconnect all drives
    5. once installed then backup the new drive if it's booting properly. Save this forever as it's a fresh new install of Windows 8
    6. restore partition from step 1 and re-boot

    then cross my fingers whaddya think? that way, in the future I can always have a choice of efi or mbr and be up and running in any disaster case in a matter of minutes.
    AND, most importantly, my system wouldn't be requiring 2 disks in order to boot into windows 8. Now that I've been using 8 for a while I like it. It is a little faster (win 7 is on an ssd also so it's a valid comparison) too.
    So right now my default system needs 2 drives to be working or it won't boot. ergo my quest.

    Make the Windows 8 SSD, disk0 & first HD boot in BIOS.Also connected to the first Sata port on the MOBO.

    (Than do a Auto Repair, if needed.)

    Well, I was successful (pretty much).
    As u can see below, i'm now booting into win 8 via efi and win 7 is there on the E: drive.
    The only problem now (and it's not that huge of a deal for me but I'll keep plugging on this too)
    is I can't just select the win 7 menu item during boot. it will just reboot to the win 8 installation. I'm pretty sure this is due to the fact that when I installed win 7 it was the c: drive in slot 0. Maybe change the UID in the boot manager? When I change the entry in easybcd to the E: it still shows the UID (Current) which is the win 8 drive.

    So if I want to boot win 7 I have to swap the cable from the win 8 drive to the win 7 one and reboot. I leave my case open so it's not difficult at all.
    On another side note...windows is showing the win 8 drive in slot 1 not slot 0. The newer motherboards are changing how the slots are numbered and they don't even show a slot 0 anymore. I have 6 sata ports and they are numbered 1-6. The disk management console in win 8 needs to keep up with that apparently.

    Screenshot below is

    Sata Port 1 Windows 8 in uEFI mode = Disk 0.
    Sata Port 3 Windows 7 in uEFI mode = Disk 1.
    Sata Port 4 Ubunttu in uEFI mode = Disk 2.
    Sata Port 2 DVD Drive.

    Set the Windows 8 uEFI mode HDD/SSD as Disk 0,
    Set the Windows 7 HDD/SSD as Disk 1, & install in uEFI mode.

    I have win 8 in the 1st slot on the MB but it shows as disk1 in the console of windows. There's another drive showing up as 0. That drive is connected to a pci expansion card. I'm pretty sure I'd have to eliminate that drive in order to get win 8 to show as disk 0.
    If that's the case when I got everything installed I'm sure if I put the pci drive back in the mix it would screw it all up again.
    Am I thinking correct here?

    and thanks again for all your help

    Yes, you are correct, as HDD on Raid cards will show first in Disk management.

    OK, I promise this is the last time I pester you.
    Below is my current config. I got rid of the pci card and installed a 3TB drive so that I was able to eliminate that 1 and 1 other.
    Now, looking at my system (The win7SSd is not installed), if were to plug in the win 7 ssd and install a fresh copy of win 7 on there wouldn't that screw up the windows 8 boot manager and I'd have to go back and fix that again?

    As above.

    Than connect SSD2, as Disk1.

    than install Windows 7 in uEFI mode to SSD2.
