I recently got macOS Mojave running on my E7440, but when I try to boot from my SSD normally, I am presented with the "Invalid Partition Table" error. This happens in both Legacy and UEFI boots, and pressing enter only prompts a "press any key to restart" option. I am, however, perfectly able to boot into my already installed copy of macOS if I do so through the Clover USB I used to install Mojave. When googling to try and find the answer to this, I could only find people with an issue the other way around, where they get this error when attempting to boot the USB rather than the SSD/HDD. The only big change I made when formatting the drive was changing the mode from MBR to Guid. I'd hope this doesn't have anything to do with the error, because I wasn't able to install macOS to the drive when I originally formatted it to MBR.
Please don't hesitate to answer or suggest something. Thanks!
