    Not the same partition. or the same drive. It does not need to be all on the same drive.

    Basically it is what I thought,, Win8 actually replaces the BCD I think. but in this case it didn't add the boot record for the Win7 boot.
    If you were able to successfully add the Win7 boot entry back in with EasyBCD (which I do believe you can by doing what you did, however, you could have just changed it to the Win7 boot, hard to say without knowing exact steps) and you can successfully reboot and choose either 8 or 7 and boot into both, you are fine.

    Yes, when you boot it will start to boot into Win8, when you choose Win7, it will re-post the system and boot 7. That is normal.

    There should only be one ACTIVE Partition/HDD, were all boot files are stored.


    As the screenshot in post 5.
    You have Windows 8 boot files on I:
    Windows 7 boot files on D:

    Should be all on the same partition.

    EasyBCD not need.

    Thanks theog and Tepid. It's times when I see so much knowledge as you both collectively have that I understand how much I don't know...

    Tepid- thanks for verifying what I am seeing having worked with EasyBCD.

    theog: Disk 0 (I: in Win 8) contains non-OS files, it is and has always been in Disk 0 (my error maybe in building the system, as you will note Disk 0 and 1 are identical hardware). As far as I know there are no boot files on this HD, unless Disk 0 always has to be the one first looked at by the system for a boot record- which I know is the way that the older PC's using IDE worked many years ago.

    Disk 1 (D: in Win 8) is my Win 7 HD. It only contains Win 7 OS and some document/data files.
    Disk 2 (E: in Win 8) is a new SSD. I mistakingly partitioned this HD thinking I was partitioning my Win 7 HD, so Win 8 in on the second partition of this drive.
    Disks 3 and 4 are external HD's containing backups and data.

    You see something in my screenshot (which I cannot) that indicates (correctly) that Win 7 boot files are on D: and Win 8 on C:.

    I think I would like to restore my system to what it was before I installed Win 8 and partition the correct HD, I understand that doing what you say would do that in pointing the boot process to the boot record on D: first?? Am I correct?

    Thanks, Bruce.

    Disk 0 (I: in Win 8) contains non-OS files,
    Boot are installed to the first ACTIVE partition, I: is
    Also boot files are hidden.

    I think I would like to restore my system to what it was before I installed Win 8 and partition the correct HD, I understand that doing what you say would do that in pointing the boot process to the boot record on D: first?? Am I correct?
    Yes, I would mark the I: partition INACTIVE, & move to Disk 2.

    Thanks theog,

    You have my image of Disk Manager in Win 8 in post #5 in this thread. I am also posting the same disks in Win 7's disk manager below. You will see the same disks, however note that "Disk 0" is now the SSD that I partitioned and installed Win 8 onto. This same SSD is Disk 2 in the Win 8 disk manager (post #5). I would have thought that the "Disk #" would correspond to a physical position that the SATA cable is intalled to... or something defined in BIOS, I'm surprized to see a new configuration of disks between the 2 OS's (and I have not phyically or otherwise made any other changes, othjer than to run EasyBCD and include the Win 7 boot files into my Win 8 boot manager.). You said that the boot files are on the "first active partition"- is the "first active partition" different when looking from my Win 7 or Win 8 perspectives?

    You said: "Yes, I would mark the I: partition INACTIVE, & move to Disk 2." Since I am currently booting now to the Win 8 boot manager, then selecting Win 7, I assume that I am initially accessing I:, then booting to the Win 7 OS. So, if I mark I" inactive, won't that stop me booting up? Or do I also need to change the boot priority in BIOS to get to the Win 7 HD?


    Thanks- I probably should go and look up some info on boot management in a PC, but any comments you might have a most welcome.

    Bruce.

    Your first ACTIVE boot partition is now D:

    Windows 7 has a little bug that some times changes Disk No: round.

    I would mark D: INACTIVE.

    Thanks theog, I have done as you suggested and all works well again, I am booting now directly into Win 7.

    Just 2 more questions- am I now free to delete my existing Win 8 partition and start over with a new partition on what is now my primary boot drive? And what should I learn from this to ensure I aren't having the same issue of not being able to boot into Win 7 next time?

    Thanks for the help, Bruce.

    Yes, you are free to reinstall,
    But why would you need to?

    I installed Win 8 on the incorrect drive (SSD) to start with, and I need all of that SSD space for my flight simulation (lots of files ). As well, now that I am booting directly into HD #2, I am now not getting any multi-boot option to go to Win 8. I guess I could use EasyBCD again, but that doesn't solve my SSD space issue. But re-installing Win 8 again now raises questions about getting back into another problem issue with my Win 7 (as occurred about 24 hours ago). Is there any reasoning as to why I would have had this issue in the first place? If I re-install Win 8 it would now be on the HD as Win 7 (separate partition).

    Thanks, Bruce.
