    Dual Boot Issues with Windows 7


    I have two hard drives (Drive0 - Windows 7 Drive1 - Windows 8). Windows 7 was working great, I booted off the CD, installed Windows 8 onto Drive1 but upon reboot I never get any dual boot options, it acts as only Windows 8 is installed. I don't think it matters, but Windows 8 seems to lock up on reboot too (maybe a seperate issue). But for now my computer is useless.

    I tried disabling Drive1 in the BIOS to force it to boot to Drive0 but I get a Windows 8 start up error saying files are missing.

    Any thoughts on how to get this dual boot setup corrected? Let me know if you need more info.

    Physically disconnect the Windows 8 HD.
    Make the Windows 7 HD, disk0 & first HD boot in BIOS.Also connected to the first Sata Port on the MOBO.

    Boot up using the Startup Repair CD or Windows 7 DVD. (not the OEM manufacturer's Recovery Disk) If you have a Netbook, you will need a CD/DVD drive.
    NOTE: Make sure no USB drives are plugged in.
    Do not use a USB Pendrive for Startup Repair.

    EasyBcd did it for me.

    But I was on a dual partition. This will seem clumsy for some, but this is what I did. I used Acronis, but any image program will do. I made a new image of Windows 7. I then installed Windows 8 (From a DVD). Went into Admin tools and shrank the partition. (Windows 8 had taken over the Whole disk and 7 was gone). I then imaged Windows 7 back to the new partition I had created and used Easybcd to set up a dual boot. I had to repeat the easybcd operation for some reason, but now all is working 100%.

    P.S. Later. I have read, since posting, that many have installed in twin partitions, with a dual boot option. I have no idea why, but I was not offered an option to choose a partition.

    I'll give it a try, I just figured disabling it in the BIOS would basically be the same thing.

    I done a dual partition today, with no problems.

    I've normally done dual boot on different partitions, but I figured I had 3 hard drives, why use paritions when I could just use another hard drive.

    I'm at work now, so I'll have to toy with this more when I get home.

    Hy there ...
    Exactly the same thinghappend to me yesterday, but with XP SP3 on HDD 1 (SATA, 3 partitions C,D,E) and win 8 on HDD 0 (IDE, 1 partition F). Installed succesfuly but no dual boot. I`m startind win 8, all good but looking to My Computer I see that HDD 0 changed his letter to C and the 3 partitions on HDD 1 are now D,E,F. Kind of scared at that particular moment, because I was absolutely shure there will be no problems this way.
    So now I couldn`t go back to my XP. Disconected the HDD 0; getting error message about some files missing (a screen that seems particular to win 8). Reconected the HDD 0 and deleted the partition using XP system DVD. No good, again. At this point I`m really annoyed, HDD 1 having all my data.
    So I insert XP system DVD, start the setup and go for a repair of drive C: (surprise, the letter is back). All goes well untill system restarts and my screen goes black, no signal (I suspect a conflict due to my video card, a Gigabyte with NVIDIA 7300, and my on board vidoe card being disabled). I`m shuting down, disconect the Gigabyte, enable the on board video card, the computer starts, but can not load all services and restarts automaticaly. I`m getting BSoD with the message: Windows SubSystem system process terminated unexpectedly and dumping all memory on disk.
    A new repair did not work.
    Do you have any idea on making it work without reinstalling fresh ?
    Thanks for reading this.
