Arrived in California for a summer internship.

I remembered last last night that not only did my laptop's Windows setup really need a partition with more space, the version of Linux Mint that I was using on another partition was no longer supported. So, since the night before your flight is a great time to reinstall Windows and Linux (you're up anyway, right?), I decided to install Windows on the larger 3rd partition and Linux on the 4th one, reformatting those partitions without resizing them. Turns out that the version of GParted on the Linux Mint disc ****ed up the MBR, including its partition table

although luckily, OS X depends only on the GPT, which was untouched by GParted, so it booted just fine. Still, error messages from
gptsync are never a good sign.

And I don't remember ever having this problem with GParted in the past. I got pretty good at manually reconstructing the MBR's partition table with
fdisk and repairing the MBR with
bootrec.exe /fixmbr, though. Now my triple boot setup seems to be working and up-to-date, at least.
EDIT: Clarification.
