Hi there,


A few days ago, I bought my first MacBookPro mid-2010 with 1TB HDD and macOS Sierra in it.

Using Disk Utility in macOS Sierra, I created another partition Format: MS-DOS FAT and successfully installed my Windows 10 Pro to that partition.

When I boot my Mac and hold the Option button, I had two choices Mac OS X and EFI Boot (Window 10 Pro). Everything works fine until I created another partition using Disk Utility in macOS Sierra taken from my Mac OS X partition. After that when I boot and hold the Option button, I have only one option Mac OS X (the windows 10 options disappear). I try to fix the MBR but without luck, so I installed the windows 10 once again and everything, works fine.

For that reason, I decide to backup entire HDD, including all partition's sector by sector backup using EaseUS Todo Backup. The backup takes 26 hours! After that, I felt safe, so I boot to the windows and create a partition using the partition where I have windows 10. The reason why I need extra partition is that I would like to share some common data between my macOS Sierra and windows 10. Anyhow, the system crash and I decide to recovery partition from my backup. After 17 Hours, I have my data back (sort of). I can boot to the windows 10 and use command + R when I boot, but I cannot boot to my macOS Sierra.

EasyUS disk manager in windows shows me the Mac OS X as an Unknown FAT 32 partitions with the added letter D. I am able to see and copy all files and folders somewhere else.

In my opinion, the issue is that I have my Mac OS X partition in FAT32 format instead of Mac OS Extended (Journaled).


The questions are simple.

1, How to fix that without losing any data on that partition?

2, When I lose the data how to put the data back - files and folders that I previously copied to external HDD?

3, Is it there any other way how to do it (get my macOS Sierra back) in my situation?

4, Do you know any better, faster backup system for macOS and windows in one?

5, How to create the partition without crash my system again?


Thank you for your help.

If you can go into the Terminal app and with the external disk connected, type "diskutil list" and post the results here, that would help to understand what's going on.

My guess is that you started with a GPT (GUID Partition Table) disk. It maybe that you now have a MBR (Master Boot Record) partitioned disk. So that may be the reason that you can't boot but your files are intact.

I use EaseUS Disk Copy on an older (USB2) computer and it takes about 6-7 hours to clone a 500GB internal HDD. So 26 hours seems high.

For disk cloning, there's software called Clonezilla. I haven't used it so I can't tell you much about it.

If disk cloning is too slow, then you would have to backup up the individual partitions and if you need to restore, you would need to create the new partitions manually and then restore. On the Mac side, Carbon Copy Cloner is popular (I don't use it). It doesn't do a sector-by-sector copy but a file-by-file copy so it would be much faster than what EaseUS Disk Copy does.

Thank you for your reply,

I was not able to use Terminal or use command + r when the Mac starts, but I used DISKPART in windows so I can provide more pictures.The first picture shows that I can copy and paste files and folders from the partition where should be Mac os. Takes one day to copy the data to external HDD.

Caveat - I'm not familiar with the output from the programs you've used. But from what I can see on the screenshots you've posted, your disk is GPT (so my assumption about it changing to MBR was not correct). You have a HFS partition "Mac OS X" which reports as healthy and from which you can read/write files (correct?).

The FAT32 EFI partition is normal.

So it looks like your major issue is that you can't boot into the "Mac OS X" partition. If that is the case, you may be able to fix it as follows: Can you boot into the recovery partition? If so, you can run the Terminal app. The following explains how to do it:
http://osxdaily.com/2017/05/18/access-terminal-recovery-mode-mac/
(Sorry about this link, it seems to load a lot of ads but it was the quickest one I could find explaining how to run Terminal in the recovery partition.)

Type in the following in terminal:
bless --info "/Volumes/Mac OS X"
and then press Enter

If you get output to the effect that there's no blessed folder, then enter the following:

bless --folder "/Volumes/Mac OS X/System/Library/CoreServices"

and then exit out of Terminal and reboot.

If something happens along the way and something doesn't work, then report back. From what it looks like, the additional partition to share between Windows and the OSX was not created. At this point, you'd have to decide if it's worth the effort to get that extra partition or not. Maybe just use a flash drive formatted as FAT32 when you need to transfer files?

Right now I copy the files and folders from Mac OS X partition to the external HDD (takes another 5 Hours to finish the job).
At the moment I have no access to recovery mode (command + r). Because of that, I will try to take off the letter D and try again.

Thank you for helping me.

If you can't boot into the Internet Recovery (command-r), your MBP also has a recovery partition according to the screenshots you posted. Right after you turn on the MBP when the chime sounds, press and hold down the option key until something appears on the screen. You should then be presented with the bootable partitions on your disk and hopefully the "Recovery HD" will be one of them. If so, select that and see if it will boot from it.

Don't worry about it Mac partition appearing as the "D:" drive. If you try to change it, it may make things worse. Just try and see if you can boot from it either through Internet recovery or booting from the recovery partition (per the instructions in post #6) and run the commands in post #4.

Thank you for your post. I already took the letter D before I saw your post. Then I used PRAM multiple times.
The result is that I can use the Recovery mode again and I have my Mac OS X on the menu again.
Unfortunately, when I select the Mac OS X the system doesn't boot(see picture below).
The disk utility doesn't know the name of the partition where the Mac should be and also saw the partition as MS-DOS(FAT) (see picture below).
So what to do next? Is it any chance to keep all files and folders without losing it that I previously backup to external HDD? There is some Apple disk image (see picture below), but I have no idea how that works.
I don't have experience with Mac at all (only last 6 days).

Thank you.

I don't know what happened because in the screenshot where you show a choice of "Mac OS X" and "EFI Boot" and the later screenshots, the partition has lost it's name so now its "" (empty). The partition type is also "Microsoft Basic Data" which is not correct - it should be "Apple_HFS".

You have the following choices:
1) Try to fix whatever problem you're having. Based on what I seen on the Internet, I wouldn't try to fix it. It seems that nobody who has the "Invalid BS_jmpBoot" problem was able to easily fix it. Also, if data was written to the partition after it changed from "Apple_HFS" to "Microsoft Basic Data" then you've likely lost the directory/file tables.

2) Clone back what you have from your external disk to your internal disk. The white-on-back screenshots you have in post #3 shows your disk in a better state than your screenshots in post #8. It also sounds like you did some work on the disk after you did your last clone. Once you clone operation is complete, you can try again.

3) Work on your clone disk. To save some time, you can work directly on your external HDD. The point of this is to see if what's on the external HDD is OK before doing the clone operation. This is more risky but if your external HDD is not in a good state, you would have spent quite a bit of time to re-clone the disk. If you chose to do this, there are some tips I can offer.

4) Start from scratch, partition the disk the way you want it from the start, reinstall the macOS and Windows and then copy the data from the external HDD to the internal HDD.
