Dual boot Win10/Win11 question
Hi. One of my PCs is already set up for dual boot Windows10-21H1/Windows10-21H2. At boot I get a dual boot option, with a timeout for 5 seconds, after which, the PC boots into the default installation of Windows 10. The other instance of Windows 10 is there for various reasons (I won't waste valuable bandwidth explaining them!) but I rarely use it. In any event, as each instance is on a separate physical drive, it's good to know that I can boot into the other, should one drive fail.
I am being asked if I want to upgrade to Windows 11 on both installations. At the moment, I do not want to in so far as the default instance of Windows 10 is concerned (used just for X-Plane - I use another PC entirely for emails, browsing and whatever). I need to check out in more detail what might 'break'; first.
I am thinking of accepting the upgrade on the second installation of Win10 to Win11 however, (which I don't use for anything really, and is pretty much 'vanilla'), just so as I can start familiarising myself with it.
My question then (finally) is: if I do go ahead and upgrade the 'vanilla' Windows 10 installation to Windows 11, is this in any way going to affect the way the dual boot works? Is the PC looking for two instances of Windows 10, so that changing one to Windows 11 is going to mess things up? Or will I just see the same boot option when I start the PC? (I think the dual boot was set up with EasyBCD, which is fairly user-friendly as far as I recall).
Probably straight forward, but I want to know what to expect before I do anything., rather than get a nasty surprise
Thanks.
