(A/B) - No (BIG NO!), you cannot do that with one product licence.
Source: Can I use the same product key to run a Dual Boot OS | Microsoft AnswersIf you purchase one (1) retail Windows 7 edition, you may install and activate just one (1) installation at a time.
To do so would be illegal, and therefore against this Forums rules for me to discuss such matters.
I think that with the status of Windows 7, support wise and the fact that the set-up of both copies on the same system, which cannot run them both at the same time ...
If we examine the rule
This install would meet the spirit and the letter of the rule, so is OK to continue here ... .... if the same key was on different hardware it would be a completely different situation and would not be a legitimate installIf you purchase one (1) retail Windows 7 edition, you may install and activate just one (1) installation at a time.
Thank you both of you.
I will use Acronis true image 2020 to clone the disk, and i will see after.
Regarding the same license, I have drive E with Win7/64 retail license, and drive H with Win7/64 tha same license.
When i tried to activate the second one, i got an error, then call tech support, explain what i have and they activate it for me with no questions ask.
Yes, you can use the original windows disk as a System Recovery disk. If you were using Windows Backup/Restore, then that would be all you needed.
If you are using Third Party Backup/Restore software, then you need to create their Rescue Media Disk.
A Rescue Media Disk has some of the features of a Windows System Recovery disk, but they are not identical.
If all disks on the computer are present when you Clean Install Windows, then the installer will modify the Bootmanager, and you will see an option at boot screen.
If you remove your "old" system drive from the computer, before Clean Install Windows, and then there will be only one OS detected, and no option at boot screen.
Iko22 and Barman58 Update:
I used Casper 10.1 . I bought it long time ago and every time i get an update for free when they change.
I booted on my Other drive E , then i start Casper and i selected Clone (copy disk).
Because i cleaned the disk before, it took just 1 hour and 35 minutes, while i watched a movie.
Now, the trick. I reboot and i selected on Bios to boot from MARVEL which was my RAID drive.
It boot from there, and as i got on the old H , and easyBCD file, it ask me like before what i want :H or E
I selected H, and boot me on my old H drive. Then, i open EasyBCD, and edit to add a new entry - The RAID disk.
Now i have 3 entry :H,E and Raid.
Reboot again and selected Raid.
It took some time first time until it shows up, but everything was fine.
I tried some programs from the OLD H drives, and they work OK.
The BIG test. Click on the disk and select properties.
New screen, with everything about drive but GENUINE EMPTY.
After 5 minutes, finally post windows genuine, and the key.
I have to do more tests with my installed programs, but it looks OK for now.
Thank you very much guys for all the guidance and help.
