My Lenovo X1 Carbon 4th gen came with Windows pre-installed with a ton of bloatware. Reinstalled Windows just to clean all the crap off to learn that the SSD had an MBR partition table. Wiped the entire drive to change to GPT, then reinstalled Windows again and (of course) added linux. Gotta love how companies put random bloatware and crusty partition tables on brand new technology. It's ok, laptop. You're in good hands now.
