I installed Ubuntu 19.04 to an external HDD,in UEFI using a laptop.
I then tried booting it through my desktop (BIOS only, Windows 10), but an error popped up, about missing normal.mod file, prompting grub rescue>.
I figured out the normal.mod is in some x86_64-efi inside /boot/grub/ basically UEFI installed. But BIOS is trying to find it in /boot/grub/i386-pc.
Can i go to boot/grub and make copy of the x86_64-efi folder and name it i386-pc?
Is that possible or do I have to format the disk or install in BIOS?
Can anyone suggest a lossless conversion method for GPT to MBR?
Thank You

Your question is a bit confusing and very unclear. Perhaps you can edit it to clear some things up: "installed portable Ubuntu 19.04 to an external HDD" -- what are you referring to when you say "portable Ubuntu"? Are you trying to set up a dual-boot configuration? What answers did you find that say "it's not possible" and what exactly is "it" that you are trying to accomplish: Are you unable to boot at all?

And you don't need to convert to MBR. Unlike Windows, Ubuntu can be installed in a GPT In Legacy mode, it just needs an unformatted bios_grub partition at the beginning of the drive.

No guarantees on conversion, but this usually works. Converting to or from GPT - must have good backups. rodsbooks.com/gdisk/mbr2gpt.html Note that Windows only boots in UEFI mode from gpt and BIOS mode from UEFI. And Ubuntu needs an ESP if UEFI boot or a bios_grub if BIOS on gpt drives. I used to always but both as first two partitions on every new or repartitioned/reformatted drive and only used gpt.

ubuntu.isoand your physical external HDD via USB as a single boot drive. - Install Ubuntu.
