Hey all, I'm fixing a MBP for a friend. Her HD couldn't be repaired and so I backed up what I could and erased it, but then ran into an issue whereby the machine wouldn't boot from USB (despite it being visible in Disk Utility). After trying a few different things, I opted to use the machine's internal HD as the install media. I burned the installer to it with createinstallmedia, and when I switched the machine on it booted into Utilities. I used Disk Utility to create a "Macintosh HD" partition for the installation, and after a nail-biting 30 minutes or so, I had a working system. I thought it'd be a good idea to remove the "Install OS X El Capitan" partition from the drive, but realised that it's a physical volume and so cannot be removed (is that correct?). I just wanted to ask, are there any pitfalls in running OS X from a logical volume? I've rebooted the machine with no issues. Just want to check that it'll all be cool before I return it to my pal. Thanks in advance!
