I don't see a problem with having OS files spread over two disks. It currently applies to my Win10, Win11 and Linux Mint. They are on the second disk. I have a lot more OS on the first disk as well. I just installed another Win11 to the fifth disk. I had to replace my motherboard a few days ago and this Win11 install was quite different from before. When I got to the screen asking for an internet connection, the "Next" option was greyed out. Both with the install to the first and fifth disk. After numerous attempts I realized the install was disabling my onboard network card. I was just about to install a PCI network card when I decided to try a USB to ethernet device. It worked. I had internet for the install. In the meantime I'd installed Win11 with OOBE\BYPASSNRO That worked for the no internet situation. So I've had the opportunity to delete several partial Win11 OS.
No, my intention was to have 2 independently functioning disks with 2 independently functioning Windows Os, that idè i have dropped since that is not possible. But, just for fun, it would be interesting to try with another Os on that disk #2, that functions independently, boots independently.
For those with BootIt, you can copy your Windows OS on Disk 1 to Disk 2. In my computer this takes 75 seconds and the copied Windows has an entry in the BootIt boot menu. It's ready to boot. It is so simple.
Yeah i looked at bootIt and it is a nice product but nothing for me, it is enough with IFW. At least for the present time. Since it was not possible to have 2 separate disks with 2 independently working Os i have dropped the idè, maybe i will try out some other Os in the future that can function in that way. Or when my idè becomes possible in some distant future. For now, the disk is put back in the drawer. Thanks for your attention Brian K.
Yes, Brian is an expert here so anything he says is to be taken as correct. I think my question may have sent you in the wrong direction. I just like to get as much information into a discussion as possible because sometimes the little details make a difference, especially if anyone was misunderstanding anything.
