Bootcamp not working after partition resizing

Hi,

Following Loner T's advice, I'm starting a new thread.

My problem:

I run OS X 10.9.2 with an SSD which is partitioned. I have OS X and Win 7 via bootcamp. I also use Parallels to run the bootcamp partition when I don't want to restart my computer.

One day I thought I could easily resize my partitions but once I did that, I got my bootcamp ruined and I no longer can boot windows from bootcamp or Parallels.

However I do access the files from OS X.

What Loner T has asked me to try:

Please start a new thread, but it may be easily fixable.

Your GPT#4 and MBR#4 seem to be in sync.

1. Check if NTFS is intact (this should show you "R.NTFS" in the dump).

sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C

2. Using fdisk,

sudo fdisk -e /dev/disk0

setpid 4

07

flag 4

p

w

y

Reboot and test.

Unfortunately the file is missing but I hope this is still fixable.

Good to see the NTFS header intact.

Please ignore that error messages which is related to older i386 stuff and continue.

Hi Loner,

I believe you didn't notice I tried to follow step 2 but I couldn't because the file is missing.

Marco-Correas-iMac-3:~ marcoac14$ sudo fdisk -e /dev/disk0

fdisk: could not open MBR file /usr/standalone/i386/boot0: No such file or directory

Ignore that.

The file is missing but I was able to follow the steps.

However I got another error.

Windows failed to start. A recent hardware os software change might be the cause.

...

Status: 0xc0000225

Info: The boot selection failed because a required device is inaccessible.

Anything to do with my previous problem?

Thanks

If you reduced the OS X side using Disk Utility, and then expanded using the Windows side, You may have tried to create a new logical drive, but the MBR can accommodate only four entries, as you can see, it already has four. Good to see that Windows is starting up, but cannot find the MBR entry for the new space. If you move the partition header to 314493416 location, Windows NTFS headers will be lost.

I would suggest a Windows repair and fixing it so it boots correctly first. It will at least allow a backup of Windows to an external drive to save your files. Then next steps can be discussed.

One option is to delete Bootcamp after the backup, and reinstall Windows from scratch, which depends on you.

The other option is to use Winclone and allow it to see the larger partition after removing the old Bootcamp installation and restoring from a Winclone backup (this backup is different from a regular Windows backup). Winclone requires a purchase of the tool.

Thanks.

What if I try the windows repair tool and it boots correctly, can I leave it alone and don't do anything else? What are the odds?

Thanks

If Windows repair tool works, then

a. Leave it alone, but Disk Utility on the OS X side will show you a gap (if you run DU now, and promise not to modify anything 😉, you should be able to see it), or,

b. Use Winclone to backup, delete, restore and reclaim the disk space.

Got your point.

I think I'll try the WinClone solution if I ever get Windows working again =)

Check it out:

Can you post a link using an external image service (like IMGUR)? The Apple Discussions servers seem to cause problems, across several different versions of Safari and other browsers. I cannot see the link, it just shows a broken "?".

Thank you. The gap between Macintosh HD and Bootcamp is the "lost space", which seems to be roughly 14GB (if I did the division correctly).

Please run Windows repair and post your results.

Yes, it is!

I'm in the process of doing it.

Actually, I just remembered I watched a video on youtube explaining how to reduce the OS X logic drive and use WinMerge to join the Windows logic drive and the "lost space" together. The guy succeeded but I didn't. Well, at least that's what he showed on the video. =)

I'm trying to run windows repair tool but I can't.

First I tried to run it from Parallels but windows installation software can't list my Win7 partition so I can repair it.

Then I tried to run boot camp assistant as Parallels recommends:

For VM that uses Boot Camp partition as a hard disk (Parallels Desktop for Mac only):

1. Launch Macintosh HD > Applications > Utilities > Boot Camp Assistant,

2. Choose to "Start Windows Installation",

3. Insert Windows Installation Disk into your Mac DVD Drive and restart the Mac,

4. Make sure that you are booting from Windows installation DVD,

5. When prompted press any key to boot from the Windows DVD,

6. Follow step 10-17 in previous section.

Doesn't work either because the only option I have is to erase my bootcamp partition as you can see: http://postimg.org/image/f056l0lan/

I also tried to load Windows installation disc pressing C during startup but it won't load =/

Any clues?

If you are looking at this article - http://kb.parallels.com/en/5223 - steps 1-6 are important. Is your VM startup order set to "CD/DVD, Hard Disk, Floppy"? I have never used this recovery, but I have used http://support.microsoft.com/kb/927392.

To verify that the MBR update is correct

a. Can you see the Bootcamp volume in Finder on the OSX side?

b. Can you choose Bootcamp/Windows in System Preferences -> Startup Disk?

You may also want to post the output of sudo fdisk /dev/disk0 and the MBR entries can be checked.

This following steps are executed when your machine is already up and running OSX.

1. Put Windows CD/DVD in the Optical drive.

2. In System Preferences -> Startup Disk choose Bootcamp/Windows as start up option and click on Restart.

3. The CSM-BIOS layer should boot from the CD/DVD, which should provide a System Recovery console. If there is a prompt to "Press any key, to boot from CD/DVD...", please press any key and start the boot from the CD/DVD.

The goal is to start the Recovery Console and fix any startup issues which were caused by the manipulation of partition information via Disk Utility.

Yes, I can see the bootcamp volume in Finder.

No, I cannot choose Windows under startup disk.

When I hold Alt/Option after the tone it will let me pick Windows but it won't start because it needs to be repaired.

Your MBR looks correct. Can you try

1. Put Windows CD/DVD in the Optical drive.

2. In System Preferences -> Startup Disk choose Bootcamp/Windows as start up option and click on Restart.

2. Power-Cycle Mac and choose the Windows installation (not the CD/DVD).

3. The CSM-BIOS layer should boot from the CD/DVD, which should provide a System Recovery console. If there is a prompt to "Press any key, to boot from CD/DVD...", please press any key and start the boot from the CD/DVD.
