Change dual boot Win10/Win7 to Win10/Win10(11)?
Hi. I have a PC which dual boots between Windows 10 and Windows 7. I now no longer need Windows 7 on the PC and want to change that O/S to Windows 10, with a view to 'upgrading' (?) to Windows 11. (I don't think I can go from Windows 7 straight to Windows 11, can I?). The current Windows 10 installation will remain as my default.
I originally created the dual boot using EasyBCD (and I then installed iReboot to switch between them). All works well. I note that there are still ways to upgrade Windows 7 to Windows 10 for free: I can't, I think, just format the Windows 7 partition and reuse my licenced Win10 installation iso for this - even though it's on the same PC, my understanding is that only one instance per license is legal, even on the same PC? Sounds risky too to do it that way, in respect of the dual boot still working afterwards: updating my licensed Windows 7 installation seems to be the way to go.
I am very hesitant however simply to go into the Windows 7 O/S and upgrade it to Windows 10: will that somehow 'kill' my dual boot? Do I need to prepare this in EasyBCD somehow - or reconfigure EasyBCD after the upgrade? Or will EasyBCD recognise the change automatically? The goal, probably perfectly clear, is to replace the Win10/Win7 dual boot with a Win10 (same installation as current)/Win10 dual boot.. and probably upgrade the latter to Windows 11 at some stage soon.
It's some years since I created the dual boot system (which I definitely want to keep) and to be honest I have very little memory now of how it is done! Some reminders and info re. the above (is there a step-by-step tutorial for dummies somewhere?) would be really helpful.
Many thanks.
