Repairing Boot Camp after creating new partition

My problem seems parallel with this thread. I am hoping a smarter person than I on this thread can lend a hand.

I have dual boot MacPro5,1. OS X 10.7.5 on one HDD, WIN7 on the other HDD. I went to clone my "MASTER" WIN7 to another drive. Unfortunately the "ALT" drive was not clean, it had a copy of WIN7 as well. My computer booted into this "ALT" WIN7 and scrodded my "MASTER" WIN7. I can no longer boot into my "MASTER" WIN7, even when I remove "ALT" WIN7 drive. It seems like something changed on the "MASTER" WIN7. Something with it's boot record or flag. It seems awefully close to the problems in this thread.

Here are the outputs from the various commands:

Command (? for help):

After spending a good hour reading this entire thread, I found a solution which worked! Thank you Christopher Murphy.

It's important to use chkdsk again with /f because the journal may say the file system is clean when it isn't. So give /f a shot and see what happens.

Next read this. You may have to click on the link to show more information. It's not exactly clear what order they want you to try this in, I would do the following three in order all at once, then try a reboot.

/FixMbr

/FixBoot

/RebuildBcd

If those don't work, then I'd try this:

bcdedit /export C:\BCD_Backup

c:

cd boot

attrib bcd -s -h -r

ren c:\boot\bcd bcd.old

bootrec /RebuildBcd

"

That did it.

diskutil resizevolume [MountPoint|DiskIdentifier|DeviceNode] limits

For your disk this appears to be /dev/disk0s2

when i type

"sudo gdisk /dev/disk0s2"

its giving me the error again:

"sudo: gdisk: command not found"

But anyways thank you for your help. I've learnt more about gpt and mbr's.

I have temporatily solved the problem by installing rEFIt. I can now boot windows from partition 4 😀

This is enough for me so I am just goin got keep it like this for now.

Again thanks for your help 😀

This whole thread, and four posts ago I told you were to find and install gdisk. So the fact you're getting this error message that it's not found indicates you still haven't installed it.

Hey

I'm having a similar problem as everyone else in this posting. I have 5 partitions. 3 of which I created for my Mac OS Lion installation, Windows 7 installation and a 3rd for storage. Everything was running fine for quite sometime until recently. My Windows 7 installation has suddenly stopped booting. Instead of a start up screen I get:

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

File: \BOOT\BCD

Status: 0xc000000d

Info: An error occurred while attempting to read the boot configuration data

Mac OS Lion starts up fine. I'm unable to mount my "Bootcamp" partition nor the "Storage" partition. On top of that "Storage" has been renamed to "disk0s5". When I installed Windows 7 it didn't recognize the "Storage" partition that was created in Lion so it merged what it thought was free diskspace (I'm assuming the same space that Mac OS recognized as Storage) to the Root Drive of Windows 7 (Bootcamp).

Are you able to assist?

It doesn't seem similar to everyone else's problem in the thread at all. The error you're getting is totally different. And everyone else experienced their problem right after creating a new partition, while you're saying your problem suddenly spontaneously developed. You wouldn't get this error message if there were partition problems, so you probably need to start out with Windows Startup Repair.

I've already made attempts to repair the windows installation. The bootcamp partition doesn't mount and the recovery system can't detect a windows installation. I've even tried placing the hard drive into a dock and using a different mac to look at the files. But the partitions aren't even visible

Guys...I have experience the same with you all. I make partition on my macbook. then I make partition using disk utility.after that. I can not boot on my wndows.
I already install gdisk,xquartz (trying to do the resulution in page 1), but, actually I dont know what is that.
Could u explain again step by step.
Thanks.
I do this all in my macbook pro I bought last month.

sorry...double Post.
Hi Christopher....I got same problem.
Please help me.

This is my result from gdisk

So, what is the next step in order to I get back my windows OS working on my macbookpro.

Thank you

(sorry for my bad english)

Regards,

Well then chances are the volume is toast, I suspect you haven't told us the whole story if OS X is working fine on this drive, but Windows is now failing to boot. Something explains this. Anyway, feel free to post the results from

sudo gpt -r -vv show disk0

sudo fdisk /dev/disk0

You need to install gdisk, create a new hybrid MBR, and add partition 5 to the hybrid MBR, and flag it as bootable.

There was a failed boot on the Windows side. Windows booted again after removing an audio interface connected through firewire. I don't know what else to tell you.

For some reason these partitions are only visible on my macbook. If I try to view the drive on another Mac or PC then both systems believe that the drive needs to be formatted.
