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.

I tried that solution but it didn't work either.


The partition I'm taking about has nothing to do with bootcamp or windows installation.


I have two hard disks with two partitions each.


SSD: Macintosh HD (for OS X) and Bootcamp (it's blank right now since I can't install windows)

HDD: Macintosh HD Files (this one shows up in finder and I can access it) and Windows HD Files (this is the one that won't mount)


Thanks

Oct 15, 2014 7:24 PM in response to marcoac14

When you have more than one physical disk in the system, Bootcamp requires that all drives that are not needed for Bootcamp, should be removed from the system. The only exception is a Fusion drive. A Fusion drive with Bootcamp Assistant ends up with Windows on HDD only, BA will not use the SSD. This is a limitation of BA design.


Can you post the output of


diskutil list

sudo fdisk /dev/disk0

sudo fdisk /dev/disk1

Oct 16, 2014 7:22 PM in response to Loner T

Confused 😟

Just to clear things up, I don't have a Fusion drive. I installed the SSD by myself on a spare SATA port.

I always had Windows installed on a bootcamp SSD partition. I've run my mac like this for years.

This makes much more sense now. All this while I was under the impression that you had a single disk, while you have two. Your OSes are the SSD and your data is on HDD.


Since you are restarting the Windows installation, the MBR (Fdisk from disk0) indicates it is ready for a Windows installation.


Do you get an error message when you try to mount "Windows HD Files"? Is it an NTFS partition or a FAT? The MBR suggests it is NTFS (type code 07). Since you no longer have Windows on the SSD, you cannot run chkdsk on the drive which is "Windows HD Files".


If you can get Windows up an running, the Windows HD files may need a chkdsk. If it was FAT, OS X could run a Verify/Repair, but not on an NTFS partition.


Do you have any third-party NTFS drivers installed on your OS X side (Tuxera, Paragon, NTFS-3g, etc.)?


You can look at this - http://i.vishalagarwal.com/post/30387627819/ntfs-write-on-lion-or-mountain-lion

Oct 16, 2014 7:49 PM in response to Loner T

It's an NTFS partition and I do get an error.


Mount failed: The disk "Windows HD Files" could not be mounted. Try running First Aid on the disk and then retry mounting.

I have Tuxera. It's weird that Macintosh HD Files is up and running, so I don't be believe I have a faulty disk.


I don't know what's happening but I just can't get Windows working. This is driving me crazy!

I have win xp installed on a VM but the data partition won't show up in windows.


Thanks

Oct 16, 2014 7:55 PM in response to marcoac14

Can I suggest that you remove Tuxera temporarily (and completely)?


Install Bootcamp so there is no conflict between Apple NTFS and Tuxera. One of your issues is such interference and it will cause problems with Bootcamp installation. Once complete, verify the ability to mount/unmount Windows HD Files. If all this works, now you can install Tuxera and retry your tests. I use the NTFS-3g (2010) version with the UI and I have stayed with it for almost 4+ years without any issues with Bootcamp. The UI specifically allows me to selectively disable NTFS-3g for volumes.

Nov 4, 2016 11:25 AM in response to marcoac14

It's actually very simple.

1- Turn off your MAC;

2 - Insert the Windows Bootable Flashdrive that Bootcamp created.

3 - Turn your MAC on AND BE READY;
4 - Once you listen the "chime", yet in the black screen, press and hold the OPTION key;

5 - When the boot menu opens, choose your Bootcamp partition (NOT THE USB DRIVE);

6 - You'll see a troubleshoot screen, choose your language, and go NEXT;

7 - At the bottom part of the window, choose the REPAIR option;

8 - A new menu will show up. Choose ADVANCED;

9 - Then choose to FIX STARTUP (or something like this... can't remember the exact words...)

DONE

Your Bootcamp is back! At least worked for me... Twice...
