Windows 10 on all three systems is usually working well, and is the system I need because (at least at present) it enables my lan, printer and calendar (I can send the new daily outlook calendar to my other computers). Inertia is possibly the most telling reason I use SuSE (Leap 15). I tried ubuntu, and it was ok, but certainly not better.
I like my HP, but changing a hard disk, compared to the one old (mbr) and one newer lenovo's is nearly impossible. I bought extra hard drives and cloned disks on all three systems, so if all hell breaks loose, I just replace the disk in a lenovo system and replace the now dysfunctional disk by cloning the clone.
After I get the dual-boot back up on these systems, I want to work on getting my printer, linux-lan working. I like using linux to log into confidential sites because I feel security might be slightly better.
Thanks for your help.
