Windows 10: dual boot win 10/ win 7

Hi, I have been tried to install win 7 64 bits on dual boot with win 10 64 bits already installed on my laptop but always failed. I've searched tutorials but didn't find complete ones .Most of the tutos are about installing win 10 over wind 7 on dual boot but not the opposite.Please help!

:)

 

Dual boot installation?

I currently dual boot Win 7 and Win 8 on my Dell PC. I want to do the clean install of Win 10 on the Win 8 partition. My question is will it affect the Win 7 partition and will I be able to dual boot win 7 and Win 10?

Thanks,

Brian

 

I have Dual Booting Windows 7 Ultimate & Windows 8.1 Pro, Is upgrading my windows 8.1 Pro to Windows 10 will erase Windows 7 ?

I had win 7 and win 10 dual boot, running just fine for several months.

THEN last nite somehow win 7 decided to updgrade to win 10 , even though win 7 was running.

Result was win 7 upgraded to win 10. Now dual boot has win 10 on one partition and win 10 upgrade on other portion. The upgraded win 7 (win 10) is all fouled and does not function. The original dual boot win 10 works ok.

The Microsoft upgrade somehow assassinated my smoothly running system, and I am jumping thru hoops trying to get my win 7/10 dual boot restored from a March 2016 disk image (that I thoughtfully had created while everything was working smoothly). This restore
is currently in progress, and I pray will be successful .. Will find out in a few hours. BUT .. I might jump off a bridge if win 10 again updates somehow to again assassinate my system. It is inexplicable to me that win 10 installs over win 7 when I have
not agreed/selected/opted to upgrade to win 10 while running the dual booted win 7. I don't know how it happened, and I don't know how to prevent it from recurring. Any suggestions?

 

It is same - create some unallocated space on drive, boot from installation drive, install in unallocated space.

If PC id uefi, you have to turn off secure boot. Also only use usb2 slots.

 

That's what I did but never succeeded

 

See additional comments.

 

I'm looking for a clear tutorial.

 

What is to say really. You do not say why it failed. Problem is more likely due to problem of installing Windows 7 rather than dual booting.

 

Yes,indeed the problem is installing win 7

 

Are we playing 20 questions?

We cannot help you unless YOU provide us details of error messages, things you have tried etc. Regrettably we are not clairvoyant.

It contains the procedure for applying the Windows 7 image to an NTFS partition and setting up dual boot manually that way if the regular method of installing Windows 7 is failing.
