weird problem - the mac os drive was missed after hard reboot

Wallfacer · May 18, 2019

guys,

I am facing a weird problem, as below:

system: thinkpad e431

bootloader: clover

os: win10 + mac os 10.14.2

everything went well until I hard shut the system (by pressing the power button) while the os was inactive, problem was: the mac os option was missed in clover, so as the recovery option.

the partition is still there in Windows Disk Manager program, but it just doesn't show up in clover.

what i've tried:

use DiskPart tool (win) to set the partition's id:

set id=48465300-0000-11AA-AA11-00306543ECAC

sadly, it doesn't work.

anyone has any clue? thanks a lot.

i took a quick screenshot, as attached, it looks like the problem caused by some clover driver?

Make sure that the apfs volume is ok, boot with the installer and see if you can repair the volume that you have macOS installed.

Sometimes, Windows Diskpart.exe can change your macOS partition type, making it "invisible" to Clover - see section III "How to Change Partition Type and Attributes" with GPT FDisk. Also, the GUID you used to set the partition's id is for HFS+ (48465300-0000-11AA-AA11-00306543ECAC) not APFS (7C3457EF-0000-11AA-AA11-00306543ECAC) which is used by default in Mojave.

To fix,

1. Download the zip file of GPT FDisk for Windows here & extract its contents. Copy folder to somewhere convenient eg C:\gdisk
2. Confirm disk number (of disk containing macOS) with Windows Disk Management
3. Open a Windows Command Prompt with admin privileges, cd to gdisk folder and start gdisk eg if macOS is on disk no 2,

Good Luck!

many thanks, go get an attempt.

Wallfacer · May 20, 2019

update on 05/20

all attempts failed.

at the end, i created an installation flash drive, and boot the system to the installation phase, attempted

1, use Disk Tool to fix the partition -- failed;

2, use Time Machine to restore the partition -- succeeded after erase the drive with APFS format.

fianallllllllllllllllly, my Mojave is back. many thanks for your help, guys.

weird problem - the mac os drive was missed after hard reboot
