The biggest problem I've had is with Windows, not Linux. If you mess up its boot block, it is a pain to get working again. (I copied the partitions from one SSD to another and for some reason, this messed up the boot from Windows).
I've also had issues when moving a disk from a legacy bios boot motherboard to an UEFI boot motherboard. I never got that quite working so i had to install Linux on a second parition, then point that Linux boot sector to my frst install, then remove the second parition. Debugging that UEFI boot was a pain as it didn't give any error messages, it just reset-ted the system.
But neither of these two are common use cases, so I can excuse it for not being easy.
