That command saved me at least a dozen of times while playing too much with my partition table and the dual boot configuration with Linux. (Partition) Magic :-)

I really miss the simplicity of MBR-based partitioning, still need to wrap my head around UEFI and GPT

UEFI is actually a lot simpler than MBR-type partitioning as far as the user is concerned. The UEFI firmware partition is based on a FAT-like fs, hence it natively supports dual- and multi-booting and can provide a "Shell" that's quite comparable to DOS itself. There are ongoing problems with UEFI due to shoddy OEM implementations, but the basic idea is quite sensible.
