Description of problem: About 3-years ago I purchased two identical basic systems, A & B. MoBo, I5 processor, 8GB DRAM, Power supply. Everything absolutely the same. One system is my always on server ( A ), the other ( B ) is mostly a mirror image of A. I run a simple rsync of A to B just about every day of nfs directorys on A such that everything critical on A is rsync'd to B. Up to now I have been using MBR boot for both systems. Both systems have identical HD Hot Swap trays. If the A Harddrive goes down I can boot to a USB stick and swap in the drive from B and install it in A and reboot to a working system. That process only takes a few minutes and works just fine. I am determined to switch both systems to UEFI for M7. I have discovered that the above process does not work any more. I can install M7 using the x86_64 Plasma Live-DVD on A, that works fine. But if using the same Live-DVD a UEFI install on B then moving that drive over to system A it will not boot. I kinda figured this may not work as one of the features of UEFI I think is the prevention of doing just this. Is this something that we would expect would work or is UEFI really working as expected? I have not tried this using M6. I'm going to assume it will do the same thing. Yes, I do change the BIOS boot from Legacy to UEFI. Thanks.
Hi Kenny, And the UUIDs on both machines are *exactly* the same?

I believe that the UUID would be different for the two systems. Something I think that UEFI specifically prohibits you from doing. I think.
Sorry, I spoke too quickly. I have not changed the UUID of the HD as I swapped the drive back and froth between the two systems. I was thinking of the unique Bios Motherboard Serial number that is different between the two systems. I think I read somewhere the one of the features of UEFI is that when it is installed on one system it records that Serial number in the boot process and that prohibits the drive from being moved to another system. I will do more research on this.
If I go through this process with M6 MBR during the boot process there is a message presented that says "detecting new hardware" and when that is finished the boot to a working GUI proceeds normally. I have even swapped drives between two systems that are very dissimilar. This may not be fixable. I just wanted to bring up this issue so we have a record of it.
I have repeated this test using: Mageia-7-beta1-Live-Plasma-x86_64.iso and installing MBR boot. Install went fine, update went fine. I then was able to move the drive into either system which booted to a working desktop just fine.

I'm going to change this to WONTFIX as I think it's outside or ability to fix.
