Computer doesn't "forget" Win10 after removing SSD it was installed on

[cynicoren]

Hello,

I got a new computer, and i had an unused SSD in the old computer (which always run Win 7 from HDD). I decided to install win 10 on the SSD and the install that drive in the new computer.
Sadly, it seems to be a mistake, since every time I turn on the old computer, I have a Win 10 error screen - there I can choose another OS, the Win7.

Is there any way to handle this error? Will there be trouble with the Win 10 on SSD andthat new computer (someone told me Win 10 can run only on 1 computer, and once it ran, it can't be operated on a different comp).


Thanks

Hello... You need to do a "Clean install" of the SSD... because Old Windows Partitions and Boot/hidden files may be still on it.
Basically you need to use the install media-custom-drive tools and delete all the Partitions on Drive first, before install of OS.

Yes... it is One OS per computer... and Win10 has took a different approach to control this... you will 30 days to activate the OS with your Computer.

Hi. So now I need to reinstall my Win7 too?

I saw the video, it said to format the drive, but ppl told me not to format a SSD

Hello... I never mentioned "Format"... B / You didn't have a clean drive in the first place, before the OS install... you need to start over because of this... Practice makes perfect. B )
