I was trying to create an extra partition to get a file from the Windows side of my Macbook Air to the Mac side, and I accidentally made the disk dynamic without realizing it. I am now unable to boot to the Mac side (holding Alt to go into the system manager at startup doesn't even list the Mac partition), and the Windows side blue screens during boot (goes so quickly that it doesn't even get to the error code before restarting).
What can I do to fix the issue? I don't know how to make a bootable flash drive that a Mac will recognize, and Disk Utility (via Internet Recovery) couldn't do anything.
