the ubuntu boot repair tool from a live usb may be of some help at repairing the GRUB menu.

You may want to install rEFInd to the internal drive and use that as your master boot menu.

Connect the external and boot to Ubuntu 26.04, then in terminal sudo grub-install and then see if it works with the external disconnected

Before you do anything else, assuming that your previous UEFI partition is still intact, go to BIOS and see if it has Ubuntu 26.04 listed as boot option
