Windows 10: I want to upgrade my win 7 machine to win 10. Can I then install my win 7 on another device

I have win 7 installed from an original win 7 pro dvd. I want to upgrade it to win 10 now, and use the win 7 dvd to install the win 7 OS on another, older machine, as that one's old win 7 license key got switched off by Microsoft. Apperantly there were too many PCs using the same key, even though I had originally purchased it new, still in the box.Is it possible to upgrade my PC to win 10, without losing all my installed programmes, and then use the original win 7 pro installer and key on another machine?Thanks in advance.

Uninstall Win 7 upgrade

I recently upgraded one of my Xp rigs to Win 7, and i did a clean install [custom install > full] but gave me an option to install Win 7 on my secondary HDD which i did, but now i just want to go back XP since i don't really need win 7 on that rig. Weird thing is that when i boot [from my XP HDD, as selected by BIOS] I get the option to choose either OS, even though the Win 7 OS is on the other HDD.

Quick question:
How could I uninstall Win 7 from my secondary HDD, without affecting my primary HDD, since [i think] some of the Boot files of Win 7 are on my Primary [XP] HDD.


-New to 2 OS'es on one machine *Eek!

Win.10 won't boot after installing Win.7

Hi,

So i installed Win.10 via the UEFI and after installing Win.7 on Legacy Mode onto a different HDD i can't boot into Win.10 (I believe can only because Win.10 was installed via UEFI)

I tried installing the BCD Software but nope. I even tried to select my HDD but say Winload.exe error

Even tried going into the USB and try repairing but the same thing happens
