My Windows 8 partition is not showing

Hi,


I have an issue with my macbook pro (early 2011) that I’m hoping someone will be able to help me with. I have tried researching the issue on my own and haven’t found anything that fits my specific situation. I consider myself only a little above the average computer user and do not have any formal education in computers.


I had partitioned my brother’s macbook previously with windows 7 and did not have any real issue. I had looked up walkthroughs on youtube and forums. That was about a year ago. This past week I decided I would like to partition my macbook so that I could use windows. My boyfriend already owned a version of windows 8 (64 bit) that had not been used so I assumed it would be fine to use it. I carelessly did not back up my computer. I used boot camp assistant that has two checkboxes with the options of downloading the latest Windows support from Apple and Install Windows 7 or later version. I did both, which prompted me to plug in a USB drive, which I did. When it was done downloading the Windows support, it prompted me to install the cd I was using for installation, which I did, the windows 8 64 bit. Afterwards it prompted me to choose how much I’d like to partition to windows. I chose the option to divide it equally, which if I remember correctly came out to be about 159 GB for the remaining storage on my mac and about 159 GB going to the new windows partition. At some point the computer restarted and I had the option for accepting the terms and agreements for Windows, and I did, then it prompted me for a product key, which I put in. I had options for disk 0, 1, 2 etc and correlating numbers for partitions. When I had done this before if I remember correctly, one of the options should have looked something like “Disk 1 Partition 3: BOOTCAMP” and I believe I would have done a few steps after that including formatting it. But the bootcamp partition was not showing up as an option. So I decided to reboot into my mac and remove the partition and start again when I had someone to help me.


The problem is that, I can’t remove the partition because its not showing up anywhere on my mac, that I can see. I tried using boot camp again to remove it, but it just gave me the same prompts as if I had just started. I also tried going into disk utility and it does not show up there either. I also noticed that the approximate amount of GB I assigned to the windows partition was still taking up that memory. Instead of having the original number of GB of free space on my mac it is now saying I have 85.87 GB free of 159.84 GB. When I tried to partition windows again using boot camp just to see what it’d say, the numbers matched having only 85.87 GB to divide between mac and windows. After looking up various info on my mac, the only thing I've noticed showing what amount of storage I originally had is going into system report and selecting storage and seeing something called logical volume group that has 319.21 GB of which 159.02 is free, which matches the numbers of the partition I made. But I have no idea if that's even relevant or what a logical volume group even is. I should have backed up my computer and should have looked into it more before blindly diving in, but now that I have, I was hoping if someone had an idea of what could have happened or what I might have done wrong. The only solution I have come across is backing up my current computer and reformatting my mac. I’d like to try and avoid this if its possible but will if I have to.


I apologize for the wordy explanation. I was using OS X El Capitan when I did the partition, and I updated it after I did the partition hoping it might help somehow but there were no changes. If any more information is needed or if pictures are required I would be happy to do that. Thanks for your time.

Can you post the output of the following OS X Terminal commands?


diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0


The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

This your Free Space. Windows partitioning on newer Macs with a CS volume is done in two 'logical' phases. Reduce the CS volume, and creating a FAT partition in the freed-up space. BCA failed in phase 2.


You will need to do this in two steps.


1. Resize the CS volume to it's maximum size.


diskutil cs resizeVolume 1FCD8C26-C95F-4456-9002-A6B1745FE07D 0g


Here is the syntax. Note the highlighted part.

diskutil cs resizeVolume

Usage: diskutil coreStorage resizeVolume

lvUUID|MountPoint|DiskIdentifier|DeviceNode size

Resize a logical volume, which is one of one or more disks that consume storage

out of a logical volume group. The logical volume group will have more or less

available space after this operation, if it was a shrink or grow, respectively.

Specifying zero as the size asks for an "automatic" fit-to-fill-LVG operation.

Example: diskutil coreStorage resizeVolume

11111111-2222-3333-4444-555555555555 10g


2. Boot into Internet Recovery and run a full-disk repair.

a. diskutil repairVolume diskN (where diskN belongs to the following entry)


/dev/disk1 (internal, virtual):

#: TYPE NAME SIZE IDENTIFIER

0: Apple_HFS Macintosh HD +159.8 GB disk1

Logical Volume on disk0s2

1FCD8C26-C95F-4456-9002-A6B1745FE07D

Unlocked Encrypted


b. diskutil repairDisk disk0

Jan 23, 2016 12:43 PM in response to Loner T

Forgive me if I did something wrong or did not do exactly as you instructed, I'm not really familiar with terminal and have not had to use recovery on my mac before. I started doing step 1 and seemed to get a message stating 0g was an incorrect size. I did step 2 just to see what the message would be.


When I type diskutil cs resizeVolume 1FCD8C26-C95F-4456-9002-A6B1745FE07D 0g I get this message:

-MacBook-Pro:~ $ diskutil cs resizeVolume 1FCD8C26-C95F-4456-9002-A6B1745FE07D 0g

Started CoreStorage operation

Error: -69674: The provided Core Storage logical volume has an incorrect size; you should run whole-disk repair

-MacBook-Pro:~ $


When I type diskutil repairVolume diskN in internet recovery, I get this message:

Last login:

-MacBook-Pro:~ $ diskutil repairVolume diskN

Unable to find disk for diskN

When I type diskutil repairDisk disk0 I get this message:

-MacBook-Pro:~ $ diskutil repairDisk disk0

Repairing the partition map might erase disk0s1, proceed? (y/N)

Jan 23, 2016 2:24 PM in response to nattle

The first message is expected. In step 2, the value of N is 1, because diskN = disk1 as shown, but it can change when you are in Internet Recovery, hence N is a place holder to be determined by looking at the output of diskutil list in Internet Recovery. The Repair Disk and Volume should be done in Internet Recovery.

Internet Recovery can be invoked using Command+Opt+R as shown in OS X: About OS X Recovery - Apple Support .

I'm not sure if I'm just missing it or misunderstanding, but I don't see the corresponding disk number for Apple_HFS Macintosh HD. When I use terminal in recovery mode and punch in diskutil list and diskutil cs list, this is the text that I get:

Can you reboot normally and run the following commands? Here is an example.


Disk1 points to the CS volume. The next command runs a verifyVolume. Check the output.

El Capitan diskutil does not want to fix it properly. You will need to run the following steps...


1. Backup OSX and all your files - Use Time Machine to back up or restore your Mac - Apple Support .

2. Boot into Internet Recovery (Command+Opt+R) - OS X: About OS X Recovery - Apple Support .

3. Click on Utilties -> Disk Utility and Erase your internal whole disk.

4. Restore OSX and your files - Use Time Machine to back up or restore your Mac - Apple Support .


This requires a separate external disk which can accommodate TM backup - Backup disks you can use with Time Machine - Apple Support .

My Windows 8 partition is not showing
