Installed Ubuntu on Legacy Bios rather than Uefi on dual boot machine

[mahesh]

I installed Ubuntu without knowing the significance of selecting the correct Bios to run from.

So then I tried booting into the Ubuntu on the Legacy Bios but wasnt able to modify the bios config from there.
Then i was thinking maybe I cannot modify it from within the current Ubuntu as it is a configured to Legacy Bios.

Then I booted from Ubuntu on USB drive.
Installed Boot-repair and ran it.
It told me to create a Efi partition even though I already had one.
I went ahead and created another Efi partition in case Ubuntu could not read the existing one for some reason.
Still got same result.

Here are the results of the Boot-Repair

Any ideas very welcome.

thank you
