Could there be on this disk that there is one Linux install AND one Windows install?

And that for some reason we only see the Linux instance when using and external disk reader. So that the Windows instance is hidden from us.

But that somehow even if its hidden, some files like those Electrum files still show when doing searches on the disk.
So that the Electrum instance and wallet is somehow on the hidden-Windows-part of the disk and I need to figure out how to access that somehow.
