Wrong Volume Being Pointed To In Dual Boot System?

Hi

I'm puzzling over why I can't load Win10 in a dual boot system. Running EasyBCD (in win7)I find Win10 is pointing to HarddiskVolume3. After searching the internet, I eventually found that I can get the volume numbers using Diskpart and what I found may be my problem. EasyBCD is telling me that Win10 is on HarddiskVolume3 whereas Diskpart is telling me it is on HarddiskVolume2 with counting starting at 0 (zero). If this is right then of course Win10 won't load because it is looking at the wrong volume. Just how do I tell my PC that Win10 is on HarddiskVolume2. Yes, Win10 IS on the third volume but volume counting starts at HarddiskVolume0 (zero). I'm attaching two graphics which may help explain what I am talking about.



I'm hoping someone can tell me what I'm doing wrong or what is going wrong. Not only that but I'm hoping someone can tell me how to fix it. Hoping to hear from someone soon.

In Windows 7 Disk Mgmt add a Drive Letter for Windows 10, then add Windows 10 using EasyBCD which is the correct way another OS is added. Drive Letter - Add, Change, or Remove in Windows 7 - Windows 7 Forums

How was Windows 10 installed on the PC? If you unplugged the other drive during its install then ideally you would boot the choice of OS by setting preferred to boot first in BIOS Boot Priority Order, then trigger the other using the one-time BIOS Boot Menu key.

Thanks for your reply. Yes I believe I did add Win10 using that method. I should perhaps say that this is our spare PC I'm working on and last weekend when I left it it was working fine no probs at all. Yesterday I came up to update Win10 to latest build to find I had no access to USB devices attached to the system. After some playing around with possibilities I found it was the installation of TrueImage Home 2010. Thankfully that was easily sorted but I still couldn't get into Win10 and I still can't. As requested I attach a pic of my Disk Management.



If it is of any help the window that comes up telling me windows has failed to load includes the error messages:

File: \Windows\System32\winload.exe
0xc0000428
Windows cannot verify digital signature for this file

Perhaps this means something to you - it means not a lot to me. I understand it's possible to bypass signature checking but so far I can't do it as the option does not seem to be offered and I've looked several times. I sincerely hope you can come up with something as I'm getting close to doing a complete reinstall of Win10.

Sorry don't quite know what happened. Please ignore this message as the same as above.

Well now the problem has completely changed from what you said originally. If Windows 10 previously booted via the BIOS and was not dependent on the Windows 7 drive to boot, then unplug all of the drives to attempt to repair windows 10.

If you have the Windows 10 disk then you can System Restore or run a Refresh by booting it into Advanced Boot options.

You can find the latest build disc ISO file in Windows 10 - Clean Install - Windows 10 Forums. Burn to DVD with ImgBurn at 4x speed. The Repair link is on second screen.

If in doubt that Windows 10 was booting itself then first mark it's partition Active, power down to unplug all of the drives besides windows 10, then run automatic repair from the windows 10 disc.

Thanks very much for your response but I think somewhere along the line I haven't made myself clear on what I am trying to do. Nevertheless I am now up and running with a dual boot system comprising Windows 7 and Windows 10. However, I decided to start again and install Win10 afresh.

The process I adopted was to overwrite the Win 10 partition with a copy of Win7 by recovering from a backup (using TrueImage 2010). Once that was recovered I made sure I still had a dual boot system albeit that both were Win7 - both items on the dual boot menu were as previously, i.e. Win7 and Win10. This proved to be fine. I then inserted a USB stick with Win10 (latest build 10162) on it and did an upgrade install and everything went well apart from not being able to carry over my Win7 settings etc.

Once installed it took quite a bit of time to set Win10 up as I like it since so much seems to have changed from Win7 and I had to keep looking for info on the internet on how to do it. Anyway things now seem to be fine at least for the moment and although I've had to install a couple of small free programs that were missing or otherwise unavailable, the vast majority of programs have come through the upgrade seemingly without problems, at least so far.

I'm going to see how things go between now and when Win10 is officially released and just maybe I'll adopt the same procedure on our two main PCs, i.e. mine and my husbands.

Anyway thanks for your input and I'm sorry I wasn't clear enough in what I was trying to do right from day one.
