Partitioning the hard drive appears to work.
AH, then yep, its an easy matter of partitioning the drive to jusy small enough to contain windows 10 or 11. Thanks for the tip. (Note, can a,ways rspartition if need a little more room for a new program or app too).
Thr only issue though is the security issue, so might as sell keep say jusy 10 on since the 11 would nevdr be able to update for new security patches.
I triple boot linux, 10 and 11- but seriously considering a move to running windows onky from a vm but onky IF i cnz run my photo programs and painting programs from the vm well enough. With a vm i can make the virtusl drive as small as needed to prevent updates too.
