Pre-installed Windows7, BIOS in "both" mode, Linux installed after
Windows, no way to boot Linux.

Tried BIOS in "Legacy only" - nothing booted.

Tried BIOS "UEFI only", Windows booted, no way to boot Linux.
Interestingly, booting off the Ubuntu USB stick worked without the "not
a COM32R image" message, but came up in a grub menu rather than the
usual full screen menu.

Left it as "UEFI Only".

All the doco I found said that if you just install Ubuntu and elect to
have it bedside Windows, it will Just Work.

I'm pretty sure the the new install is UEFI - how can I check?

I really don't want to go down that path unless I absolutely have to.

Haven't got that far yet. As I can get wifi with a dongle it's pretty
low priority.
