    Hi there
    Linux can boot anywhere on any bootable device - including sd cards if your machine supports booting from those.

    create for EFI systems a /boot/efi and a /boot partition - both needed for UEFI systems and install your boot loader (grub2) to those partitions -- the Linux set up options should give you target devices on which to install grub2 and the system.

    You can then add Windows to the Linux boot if you so wish but you don't need to touch any part of the Windows system when installing Linux.

    Personally if I needed to dual boot I'd simply use the computers BIOS to select the boot device -- but probably even better I'd go for running say LINUX as a Virtual Machine --then no dual boot is necessary.

    If you've got W10 pro HYPER-V can be used as well as VMWare and VBOX software. on Home HYPER-V isn't available.
    Plenty of advice in installing and managing Virtual machines in the virtualisation section on the forum.

    Cheers

    Thanks for jumping in, Jimbo, but recall (from my original posting) that this is not a UEFI system, but a BIOS one. The firmware and hardware, including the SSD, are the same as when the scheme involved Win7 and the dual-booting of Ubuntu from the Windows boot manager/BCD worked. Something seems to have changed with Windows boot operation sometime after Win7.
