Windows 10: Upgrade one side of current Dual boot setup

All,
My current computer is already in a dual boot setup with a dedicated Win7 SSD and a dedicated Win8.1 SSD (not just a partitioned drive). Both drives are booting through BIOS not UEFI. What I would like to do is Upgrade the Win8.1 drive to Win10 and keep the Win7 drive functioning as is and intact. Both of my current versions of Windows are completely legal with their own separate Product ID's.

I've done some initial research on this question but was hoping to get some answers from someone that has done this or at least some "best practices" on subject. It seems that from what i can find that my best bet is to disconnect the Win7 Drive, upgrade the Win8.1 drive to 10, then reconnect the Win7 drive and hope for the best.

Any help or suggestions would be greatly appreciated. Sorry in advance if this topic is covered in a different tread already.

Thanks!

:)

 

Can I dual boot Ubuntu after i upgrade to Win 10 from Win 7?

I currently have Windows 7 and Ubuntu installed side by side on my laptop and dual-booting is achieved through the GRUB boot-loader.

If I upgrade my Windows to Windows 10, will I be able to dual boot Ubuntu and Windows 10 or not?

Please help..

 

Windows 10 very slow performance since I dual-boot

Yes, your hardware sounds like a reasonable gaming system, your RAM is a little on the slow side by current standards, but you have lots of it. You don't mention the type of drive you have. In general, if you have HD, swapping it out for a SS will make
your system seem like it has been significantly upgraded.

If you really have setup a dual boot, where at the start of the boot process you have to select the OS, then having Linux will NOT impact Windows. They are invisible to each other because they are on separate partitions. And Windows literally cannot see

If you have it setup some other way, then yes, there may be an impact. Please provide us with more details of how you setup the "dual boot".

 

Hi and welcome.

I recommend doing exactly as you have stated, Remove the Windows 7 drive and then do the upgrade. I would also create an image of your Windows 8.1 drive just in case.

 

Exactly !!
