Boot Camp disappeared after El Capitan update

I am a sailor and due to report to my ship & sail out this coming Saturday 10/10/2015.

I have a mid-2009 13" silver MBP which also has win10 loaded using boot camp. The Win 10 side has all my USCG certifications, professional licenses, email exchanges with USCG, accounts, etc.

I downloaded and installed El Capitan and after rebooting, I noticed the option of booting up in Win 10 gone. Pressing the Option key gave me 2 options of booting up either in El Capitan or the Recovery Disk. A friend put in the following sudo command, "sudo nvram boot-args="kext-dev-mode=1 rootless=0” and now the boot select screen does not show that option either.

This is what diskutil list shows:

/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *250.1 GB disk0

1: EFI EFI 209.7 MB disk0s1

2: Apple_HFS Xxxx Xxxxxxxxx 154.1 GB disk0s2

3: Apple_Boot Recovery HD 650.0 MB disk0s3

4: Microsoft Basic Data 75.2 GB disk0s4

When I type diskutil cs list into Terminal, I get No CoreStorage logical volume groups found.

Typing sudo gpt -vv -r show /dev/disk0 got

gpt show: disk0: mediasize=250059350016; sectorsize=512; blocks=488397168

How can I undo the sudo command and get back the Win 10 partition? I can't see the Boot Camp/Win 10 partition neither in .

Someone has suggested that I use the sudo bless –folder /System/Library/CoreServices –setBoot command. Should I?

PLEASE HELP. I need to get access to my documents and co email before Saturday.

Thanks in advance.

Your output does not have addresses 00-90. Can you please post it for verification?

Also, a few months back I had re-partitioned the hard disk with both Yosemite and Win 7 on it, to make space for Win 10.

This is a bit confusing. Did you have all three, Yosemite, Windows 7 and Windows 10 as separate OSes at the same time? And you could switch between all three? If yes, it would require some esoteric partitioning on your 2009 Mac. Your 2009 Mac officially does not support W10 according to Apple.

How can I undo the sudo command and get back the Win 10 partition? I can't see the Boot Camp/Win 10 partition neither in .

Someone has suggested that I use the sudo bless –folder /System/Library/CoreServices –setBoot command. Should I?

PLEASE HELP. I need to get access to my documents and co email before Saturday.

Let us do one step at a time. In the current state, I do not want to make the problem any worse than what it is. The Bless is just controlling boot ability. If the partition header(s) is(are) incorrect, no amount of such commands will help.

Can you also download the following two pieces of software?

Testdisk - http://www.cgsecurity.org/wiki/TestDisk_Download

GPT Fdisk - http://sourceforge.net/projects/gptfdisk/

These will help in scanning the disk and for potential issues and fixing them as necessary.

This looks like your partition table.

GPT 3 Start	GPT 3 Size	GPT 3 End	NTFS Start	Sector Offset	NTFS Size	NTFS End	Sector Offset (MB)	NTFS(Gb)	Disk End	Disk Difference
301429960	1269536	302699496	302700544	1048	185696249	488396792	1	88.55	488397168	376

Scroll down to the partition with the NTFS Start value (the second MS Data in your list) and press 'p' to list files.

Your screen should look similar to the following (please post a screen shot or what you see).

Scroll down and you should see System Volume Information. It will confirm that this is the correct partition. I can then give you the next steps.

You there? I pasted the System Vol Info quite some time back 🙂

Thanks 🙂

Install GPT Fdisk (aka gdisk). Leave your Testdisk display and start a new Terminal Window. You need to use the following steps. If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8. Please notice the'+' sign in step 8 (this is called offset notation). The text in parentheses is for informational purpose to describe the action being taken. Gdisk has one-character commands except when entering numbers.

Rebuild GPT4 using start/end offsets

Sudo gdisk /dev/rdisk0
P (print the full list of parts)
D (delete)
4 (part 4)
N (new part)
4 (part 4)
302700544 ( - Start offset in sectors or the start point for Bootcamp part)
+185696249 ( - Size offset, as opposed to End offset)
0700 (Windows part type)
P (print list of all parts just to see what changes will be made)
W (Write the new GPT)
Y (Yes! really write the new GPT)

This will delete and re-write the GPT partition info for /dev/disk0s4.

Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 10. Accept all other defaults that Gdisk offers. Please see thesample Q&A as an example. These steps can be repeated if you make a mistake before you get to Step 12, otherwise start from Step 1 for these steps. Step 6 has numbers which are typed with a space between the numbers. Please see the sample Q&A before you execute these steps.

Sudo gdisk /dev/rdisk0
P (Print list of parts)
R (Recover)
O (print current Hybrid MBR)
H (chooses Hybrid)
Partitions numbers to be hybridized: 2 3 4
Y (Good for GRUB question)
N (part 2 boot flag)
N (part 3 boot flag)
Y (part 4 boot flag make NTFS bootable partition)
O (print current Hybrid MBR)
W (Write the new MBR)
Y (Yes! write the new MBR)
Reboot

Here is sample Q&A for this section. Please notice the Press Enter/Return.

Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y

Creating entry for GPT partition #2 (MBR partition #2)

Enter an MBR hex code (default AF): Press Enter/Return

Set the bootable flag? (Y/N): N

Creating entry for GPT partition #3 (MBR partition #3)

Enter an MBR hex code (default AB): Press Enter/Return

Set the bootable flag? (Y/N): N

Creating entry for GPT partition #4 (MBR partition #4)

Enter an MBR hex code (default 07): Press Enter/Return

Set the bootable flag? (Y/N): Y

Test 1 - Does Bootcamp Volume show up in Finder?

Test 2 - Can you see files in Bootcamp Volume?

Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?

Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.

Hello Loner T

Thank you very much.

Followed your directions and could see Boot Camp in:

1. Finder

2. Startup Disk &

3. Disk Utility.

I could enter the Windows side of the disk thru Finder and access my documents. However, when I tried tried holding the Option Key and enter Windows, I could not and got the error message: Kernel is missing or contains errors. Error Code: 0x0000098. So, in a way Test 4 was unsuccessful.

Google tells me to have an install disk ready. I guess I'll have to download Win 10, create an ISO file and do some repairs 🙂, unless you know of an alternate method 🙂, which would be even better as I won't be back home from my ship till mid-January 2016 😟

One question:

BootCamp Assistant gives me 2 options: A) Download the latest Windows Support software from Apple and B) Remove Windows 7.

Do I really need to download? Apple no longer supports the mid-2009 MBP for Win 10 and after some Googling, I download the pertinent software for the camera, keyboard, mouse and speakers that enables me to run W10 smoothly.

Thank you once again for saving my bacon 🙂

Can you boot in Windows Safe Mode? If you can get to command prompt, try running chkdsk. If that does not work then you will need startup repair. This error can also happen if your BCD is corrupt, which can be fixed using Windows Startup Repair.

You can use W7/W8+ drivers and install them with Administrative rights and computability set to W7/W8 as an option.

At least you have access to your files, which can be backed up.

Nope. Unfortunately not. W10 automatically goes into Repair/recovery mode and gives me the blue screen with that error message. But at least, thanks to you, I can access my documents. And, thankfully, I have access to most of my passwords to the important web sites via cloud 🙂

Once again, thanks for helping and saving me 🙂

Can you try using Shift or Shift+F8 to see if you can a Recovery Console for Windows?

No. Cannot do that either. Get the same screen. But, I've run into another problem. How do I get Apple to boot from the W10 ISO DVD as till I do that, I cannot repair W10? I'd prefer to repair rather than doing a re-install. Any ideas?

Thanks.

Is it a mixed 32-bit and 64-bit DVD?

Boot Camp disappeared after El Capitan update
