Acronis Recovery is now bootable
I had been unable to boot from a disk recovered by Acronis. The reason was Acronis restores the MSR partition in the incorrect order which changes the partition number of the EFI partition so the disk doesn't know how to boot. What has changed that now all of a sudden my disk knows how to boot?

If you were getting a message that was basically saying to install the boot disk and try again then perhaps the boot priority was wrong in the system bios and eventually corrected itself.

Technogod,
Your question has a very complicated answer. There are a number of factors at play. First, Acronis makes an effort to adjust the BCD file that controls booting during the last phase of a recovery to make it point to the new location of the EFI partition. Second, UEFI computers actually write to the BCD file during the boot process and can change the EFI partition being used to boot. This becomes important when there are more than one disks present with Windows systems. I can tell you I have a computer with 3 Windows system disks. The UEFI firmware has set the BCD in all 3 systems to boot from the same EFI partition on one of the disks. It's a little annoying, but it actually does work. When it does present problems is during cloning or restoring to a different disk.
Not knowing your exact procedure makes it impossible to explain your results. The new disk may have become bootable because you changed the number of disks in the computer, perhaps removing a Windows disk. That could explain why the UEFI firmware corrected the BCD file to made it bootable.

Acronis makes an effort to adjust the BCD file that controls booting during the last phase of a recovery to make it point to the new location of the EFI partition. That explains it. Previously Acronis was unable to fix their inability to restore the partitions in the correct order. It's about time!
