Windows 10: Can windows 10 be reinstalled on my device after my change of os

I bought my laptop with windows 8 and upgraded freely to windows 10 in the time of its release after updating to windows 8.1 Then i changed my OS to ubuntu and now can I get back my windows 10 on the same laptop.

Upgrading cpu and mother without reinstalling windows 10

in most cases you can do exactly what you are trying to do by taking the os drive and plugging it into the new system and booting in safe mode. once in safe mode open a command prompt as administrator and type "set devmgr_show_nonpresent_devices=1" hit enter. then type "start devmgmt.msc" hit enter again and device manager should open up. after that click the "view" tab and select "show hidden devices". then you just expand each list and unistall all the drivers that are slightly transparent. once you are all done go ahead and reboot the system and install all the new drivers. in most cases this is enough and does not need anything more done.

edit: just boot the os into safe mode the first time and let it install drivers then reboot and fallow the steps i listed above. back with windows vista and earlier windows versions this would be problematic but sense 7 ive found that swapping boards from different manufacturers and even amd to intel has become mostly doable. ive done it a handfull of times.

 

Reinstall Windows?

You don't need to reinstall windows. Go to the device manager and remove uninstall the processor and motherboard drivers listed. When you start the system back up you should be able to re-install the new ones. I just changed my mobo/processor Friday, everything is fine.

BTW I have seen some reviews that state practically no difference in using more than 2gb of ram.

 

How to change the MB without having to reinstall windows ???

Suggestion

Before you turn off Windows for the last time prior to changing MBs, go to Device Manager and delete everything you can, with no mercy, especially the items under "System devices".
Then next time you boot (after changing MBs hopefully), Windows will re-install everything again, but this time according to the new hardware.
Works quite well... Good luck!
