Dual Boot Windows 10 and Windows 7

I have just 'upgraded' my Windows 7 working partition to Windows 10 and it all worked OK and the desktop looks identical in both. I did this using Macrium Reflect to take an image of W7, update to W10, save the W10 image and then put the original W7 image back.

I intend to continue to work with W7 so that I am compatible with the organisation I volunteer with. I would like to make my pc dual-boot so that I have W7 on one partition and W10 on another.

If I do this which OS should be on the C: drive and which should be on another. When I originally tried to update W7 images on my E: drive, the W10 update did not want to know.

Many thanks for any help or advice.

Do you have a second license for Windows? In order to dual boot, legally, you have to purchase (or use an already existing) second license for Windows. When you upgrade Windows 7 to Windows 10 you do not gain a new, second license for Windows, you still have only 1 license = 1 installed version.

Yes I already have a second license for Windows 7 purchased a while ago through eBay and never used.

I have already read the thread that you gave me the link for but it deals with installing a new copy of Windows 10 on to the second partition. I am interested in any comments or problems that anyone has had when a copy of Windows 7 on drive C has been updated to Windows 10 and then a image taken. Another image is then used to put that C drive Windows 7 again and the image taken of the converted Windows 10 partition is restored to a partition on the same hard drive but to a different partition letter such as E: Will the create problems running Windows 10 from this E: drive.

After you restore the Windows to E: drive, you will need to add it to the boot menu. In the Windows you are booted into, open a command prompt with administrator privileges. Run:
bcdboot E:\Windows /d /addlast

If it isn't E:\ drive, just put in whatever drive letter it gets. When you boot into the newly added Windows, it will get C:\ drive when you boot into it.

Thank you for the information. I have now restored the W10 image and I actually used the program EasyBCD to set up a OS choice program as part of the start-up. It all works as it should. I can now continue to use W7 for my 'work' and look in to W10 when I want to.
