PepperMint Linux: installed uefi but it is not uefi issues

this is a peculiar install.

I decided to install PepperMint Linux (again) after it went to ver9. it was a live with persistence via unetbootin method to usb stick, I have a MBR Legacy install/boot Laptop system, period. this failed to boot something about "something'32 failed to boot cannot locate error,

when I selected boot from the USB Port. then I just set my BIOS to pick the USB Port first on the list, it booted, as eufi because I also had to boot from UEFI in my BIOS turned on.

so it must have seen the ufi part on the stick and booted it, as it said failed uefi boot something something, then booted anyways into the live OS, I installed from there onto partition, it took until it got to install grub part, that failed, no big deal manjaro Linux is controlling the grub.

Luckily it did not screw up manjaro's grub, as I was able to boot it, then get into manjaro and update-grub, it picked up the new install of Peppermint, but in Peppermint I am getting the efi grub issue message whenever I run apt-get 'anything'

Setting up grub-efi-amd64-signed (1.93.5+2.02-2ubuntu8.4) ...

Installing for x86_64-efi platform.

grub-install: error: cannot find EFI directory.

 dependency problems - leaving unconfigured

Errors were encountered while processing:

 grub-efi-amd64-signed

 shim-signed

E: Sub-process /usr/bin/dpkg returned an error code (1)

as it is NOT really a UEFI nor suppose to be a UEFI nor can it ever be a UEFI OS due to the partition table is NOT GPT nor is it set up in any fashion to be GPT or UEFI as a result of it.

so I was wondering if anyone knows what needs to be modified within the system as it is so it will no longer think it is UEFI and stop getting this message.

thanks ahead of time.

I think I found it, just need to check a few things and reboot to be sure.
Just installing its grub onto the mbr /dev/sda failed and had to do this so far.

Code:

apt-get purge grub grub-pc grub-common

apt-get install grub-common grub-pc

"MBR Legacy install/boot Laptop system,"

" then I just set my BIOS to pick the USB Port first on the list, it booted, as eufi because I also had to boot from UEFI in my BIOS turned on."

I'd start here. "grub-install: error: cannot find EFI directory." Are you changing back to legacy in this deal?

got it fixed. I think they the people at peppermint needs to fix their iso as it was not working as I created the stick that caused me to give the shot in the dark turn on my uefi in BIOS, anyways, I just needed to purge gurb2 off my system then reinstall it then update it as stated in post above yours. thanks

Thanks for the update. I was typing a reply to the issue, didn't know you had it fixed. :)
