I previously was dual booting macOS and Windows 7 on my MacBook but I also needed a Linux partition. So I tried to resize my Windows partition and made a new partition for Linux. When I booted back to macOS and added the unallocated space to the Mac partition (APFS), there was an error which said I couldn't create a new partition. So I restarted the computer, but I could only boot Windows (no Mac option). The bad news is that I haven't made any backup before. Can anyone tell me how to recover unbootable APFS partition on High Sierra?
Some advanced users always have multiple operating systems installed on a single Mac so that we can enjoy all functionality and professional features of different systems on one computer. But there are many drawbacks of having multiple operating systems. The major one is that one of operating systems becomes unbootable. Just like what happened above, due to the APFS partition not bootable issue, we can't turn on Mac operating system and all data on Mac is lost.
Apart from the above situation, APFS partition not bootable problem also occurs to anyone at any time. We are possible to meet it when installing High Sierra, or during our Mac computer startup, even when we don't make any change to Mac. This issue is caused by virus infection, human error, corruption of head file, bad sector, catalog files node corruption, failed hardware, etc.
