Question:

Question: Hard disk space lost when Bootcamp failed

Hei guys,


I've Late 2011 MBP with High Sierra 10.13.

I tried to install Win 7 and during the process, things went wrong and finally lost 75 GB (out of 1TB) space on my HDD.

The discussion at Lost Space After Removing Bootcamp Partition is similar to mine. However, some info provided by the user in that post is different than mine. So, I'm posting the problem here again.

The info requested for in that post is as below:


Output of diskutil list

/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *1.0 TB disk0

1: EFI EFI 209.7 MB disk0s1

3: Apple_Boot Recovery HD 75.7 GB disk0s3

Please note that the first screenshot shows only 924.35 GB while the second one shows 1 TB.

In page no 2 of the above mentioned discussion, it was discussed that OS has to be reinstalled. So, related info from my side is:


No backup of any kind (manual, time machine etc).

MacOS backup - downloading of High Sierra in progress at this moment.

FileVault turned off.


If I try to install Windows 7 in the current state of things, and with Windows partition size as 75 GB, I get the following error.


User uploaded file


If I keep the partition size as 100 GB, Bootcamp spends a lot of time at "Status: Partitioning disk..." and finally throws an error as above.


Please suggest further action.


My ultimate destination is Windows 10. When I tried to install Windows 10 via Bootcamp, I got a message that Windows 10 can't be installed. So, I am planning to install Windows 7 first and then upgrade to Windows 10. Is this right way or something went wrong during Windows 10 installation?

Hei Loner T,


Thanks for the pointer.

Basically, it tells to erase the internal HD completely and restore from TM.

The problem is that I don’t have a TM back-up and am not in a situation to get one immediately.

So, instead of this procedure, can I try one of the following?


  1. Boot to recovery (local) and reinstall OS? Will this delete any of my files?
  2. Boot to internet recovery and reinstall OS? Will this delete any of my files? What if internet connection breaks briefly during installation?
  3. I’ve a bootable external disk (320 GB) with Sierra. Can I boot through this and reinstall OS on internal disk? Will this delete any of my files?
  4. Create a bootable external disk with High Sierra and follow point no 3?
  5. Delete recovery partition completely (thereby merging that space with main partition) and depend on internet recovery and hope it works when required. This will be temporary as I’m planning to buy an external HDD in a couple of months for back-up. Once I’ve a back-up, I’ll reinstall macOS properly on internal disk.
  6. Any other better procedure?


In any case, can I not install Windows without resolving this issue? I'm ready to forego that extra space occupied by recovery partition till I have a proper backup and reinstall macOS.

Regards,

Babloo

Create an external bootable High Sierra installation. Merge the current local internal Recovery HD into the macOS installation using diskutil mergePartitions and re-install HS using the external disk's local Recovery HD which will keep your internal non-OS files intact. Once it is the proper size, then you can try the BCA partitioning again.

Hei Loner T,


Sorry for the delay in responding. Got busy with other things yesterday.

Now, my external HDD is ready with HS and am about start reinstallation on internal HDD.

However, my doubts are

1. Will I lose passwords & history from Safari?

--> If I back-up the folder "~/Library/Safari" and then replace after reinstallation, will I get back passwords & history?

2. How about other built-in programs like Notes, Messages etc? Will I lose that data?

--> I can copy the contents of Notes to TextEdit or something and copy them back after installation. Is this the best way?

--> I don't user Messages much. So, this is not a big worry for me. But, asking just for info.

3. I believe the user account and other related folders (Pictures, Music, etc) won't be disturbed. Right?


In your earlier post, you mentioned that internal non-OS files will be left intact. But, I don't know how separated are programs like Safari, Notes etc are, from OS. So, asking this.

Babloo.

Hei Loner T,


I installed the OS but things don’t seem to be as they should.


Output of 'diskutil list' is as below:


/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *1.0 TB disk0

1: EFI EFI 209.7 MB disk0s1

2: Apple_CoreStorage MacbookPro-1TB 999.3 GB disk0s2

3: Apple_Boot Recovery HD 650.0 MB disk0s3


/dev/disk1 (internal, virtual):

Logical Volume on disk0s2

131F96D3-9067-4E87-B1B5-6A6D00DB095B

Unencrypted


Please see that there are two disks: physical & virtual.

Recovery partition is shown only in physical disk.

Whereas, in virtual disk, there’s no recovery disk and EFI partition & 1GB space are missing.


Disk Utility is as below:


User uploaded file



User uploaded file


If I boot with ‘option’, it shows only the main partition, no recovery partition.

If I connect external disk and boot with ‘option’, it shows main partition of internal disk and main & recovery partitions of external disk.


The installation process went like this.

  1. Booted into recovery partition of external disk
  2. Disk utility —> Reinstall OS
  3. Select internal disk
  4. Installation started.


Note: In the first instance, installation was started around 12.00 PM on Saturday and it showed a remaining time of ~2.5 hrs. Around 1.00 PM, it showed ~1 hr and it was stuck at it till 2.00 PM. I then quit the installation and rebooted. Everything looked as it was before installation. Then, I restarted the installation at 3.00 PM and it showed remaining time of ~10 hrs. I let it proceed at its own pace. It was completed some time during the night and when I checked at around 7.00 AM on Sunday, it was completed.

After booting, the observations are as given above.


Why did I not get the recovery partition now? Why are there two disks, physical & virtual?

What’s the way forward?




Regards,

Babloo.

This is normal, and expected behavior. Your 'virtual' HFS+ file system is encapsulated in a CoreStorage logical volume/volume group. High Sierra will not convert a HDD to APFS, but a CS LV/LVG is a valid configuration for a the disk.

Hei,


I installed Win 7 Pro N successfully and everything was fine.

However, I wanted Win 7 Pro. So, in order to reinstall with Pro instead of Pro N, I deleted the BC partition from Disk Utility. Now, the windows partition is merged with Recovery partition.


Output of diskutil list is as below:

/dev/disk0 (internal, physical):

0: GUID_partition_scheme *1.0 TB disk0

/dev/disk2 (internal, physical):

0: GRMCNPRXFRER_EN_DVD *2.9 GB disk2



When I tried to merge Recovery partition with main partition using terminal, I got the following error.


"diskutil mergePartitions JHFS+ MacBookPro-1TB disk0s2 disk0s3

The chosen disk does not support resizing.

Do you wish to format instead? (y/N)n D

Merge canceled".

So, how do I merge partitions?

After merging partitions, do I have to follow the same earlier procedure (Boot from external HDD Recovery partition--> Reinstall MacOS --> BCA) to install Windows?

I understand that I deleted Windows partition in wrong way. What is the correct way?

This is a bad thing to do. If you partition using BC Assistant, you should also Remove.Restore using BCA. Disk Utility does not work correctly. In High Sierra, DU causes other issues.

This size is a combination HS and DU causing problems. The Recovery HD is supposed to be 650+ MB, not 70+GB.

This is normal and expected behavior. JHFS+ volumes cannot be merged in a CS volume or vice-a-versa.

So, how do I merge partitions?

There are two ways to do it,

  1. Notice the Revertible is currently yes. You can use
    1. diskutil cs revert 131F96D3-9067-4E87-B1B5-6A6D00DB095B
    2. diskutil mergePartitions jhfs+ "MacbookPro-1TB" disk0s2 disk0s3
  2. Convert disk0s3 to Free Space and add it to Macintosh HD via DU, and then re-install macOS to get Recovery HD back.

Hei Loner,

Thank you for the reply.

I followed the steps and started the reinstallation around 00.30 hrs today. At that time it showed a remaining time of ~8.5 hrs.

By 8.00 AM today, it showed remaining time as 3 hrs 5 mins and it got stuck there. Even by 11.30 AM, it remained there. So, I quit the installation and will restart it tonight.

I believe the installation files are being downloaded from Apple server and that's the reason for such a long installation time. Is there any way to install using the installer that I downloaded from app store?


Regards,

Babloo.

Can you post the output of


diskutil list


It is possible to install from the Installer downloaded from the App Store. See How to create a bootable installer for macOS - Apple Support , but you will need a working Mac to execute the steps.
