SOLVED Installing Mageia 5 for uefi boot fails to boot

I have not been on here for a while. The old Dell up and died on me. Built a new box and have been setting it up and learning to use something quite a bit newer than the 2008 Dell. Specs in sig.
As this is a new MB it runs on uefi. Has legacy bios boot support and that is what is going on with my internals as I just put the old drives in to see if it would work and it did.
But I have an external formated to GPT. This is where I am attempting to install Mageia 5. Install seemed to go well. Installed from the DVD image. Image was put on a usb stick using dd. md5sum was correct. I disabled the onboard sata support before installing so that the internal drives would not be a factor.
Doesn't boot. In my boot menu I get 3 entries for Mageia.
The first seems to be the one is the default. Uefi "bios" set to boot from usb device first, this is the option it picks. Selecting it causes the screen to go black, then the Asus logo reappears with nothing else on the screen. That is permenant and only the power button will cause it to reboot.
Second option is really strange. Boots to a menu. For the install media. Can find no trace of the install media on the drive. Have not tried booting from this menu.
Third option tells me I need to mount the kernel first and lands me in grub rescue mode. This I am not expert at and have had no luck with.
This was true with on board sata support disabled and enabled.
But opening the file system for the new install it all looks like it is there. The fat partition for efi boot is there. Populated even;
/etc/fstab has this entry;
/boot/EFI is unpopulated. This seems to me to be the problem but can't for the life of me figure out what to do about it.
The drive was set up using gparted to create the GPT on the old Dell. This could be a problem. I was, at that time, simply interested in trying GPT. Love it.
Only thing on the drive currently, besides the the new install (efi, /, /home /Shared (data), /swap) is the Shared data partition. This contains some stuff, way out of date, from the data partitions on the 4 internal drives. Linux files I have written/collected as notes on administration and so forth, music, movies. Nothing I can't simply delete with no problem.
One solution I am thinking about is simply wiping the drive, let Mageia reformat the thing from scratch and add the same partitons leaving about half the drive empty for future installs.
This might work. But I would rather wait and see if someone has an idea about fixing this problem. Seems like it should be curable. This is my first attempt to actually boot uefi and would like to actually learn something rather than simply reinstall and hope for the best.
Could be I simply did something wrong during the install process. I am much more familiar with the Debian installer and most Debian branch installers are very similar to it. So I feel this is a very possible cause.
Will be happy to provide more info. May be on here in a rather spotty manner until the weekend. Work is so inconvenient when you have an interesting problem.
