I have fix it! Have been reading older post by Loner T all day yesterday!
In case others have similar issue: You should read this discussion where elikeness has concluded what Loner T have told.
Bootcamp partition has disappeared after upgrade to Yosemite 10.10
For me, I did quick search (test disk) on /dev/disk0
and I found a partition that store all my window files.
So I use that partition start/end sector to config GPT and MBR.
After reboot, check in disk util that the partition is mounted and detect as bootcamp.
Check hex dump for R.NTFS string.
Reboot again with "option" button down and boot window
Thanks Loner T for all the help!
You must be exhaust with this issue.
Hope Apple give out a new patch with this fix or automatic quick fix solution.

Upgraded to Yosemite and Windows 8.1 Pro in Bootcamp, can no longer drive retina display and two external monitors simultaneously?

Greetings
I just upgraded from Mountain Lion and Windows 7 Ultimate (Bootcamp) to Yosemite and Windows 8.1 Pro on a late 2012 MBP 13" Retina. Prior to the upgrades, I was able to drive the retina panel and two external monitors simultaneously when operating directly in Bootcamp. Now, I can only drive 2 of the 3 simultaneously though all three are recognized under Graphic Properties. I simply cannot find any option or profile under Graphics Properties or Options or Personalization to run all three screens.
My hardware hasn't changed and this worked prior to the updates. I have no issue on the Mac OSX can run all three. I also have no issue doing it in Windows under Parallels Desktop 10. It is just when I boot directly into Bootcamp that this happens. What am I missing?
Thanks,
G.

Great point, Loner T. It was late when I was working and I thought about this afterwards also.
The issue was that in Windows=>Control Panel=>Display, under "Change Display Settings", the three screens showed but "Extend Display" was not selected for one of the screens. It was simply off. I can't believe I danced around this w/o picking it up sooner. In fact, it has happened in the past that for some reason a display loses this setting.
As an aside, thanks again for all of your help and terrific input to upgrade both the Mac and Windows operating systems. As I was going from Windows 7 Ultimate to Windows 8.1 Pro, one thing I did come across that made life much easier was to upgrade first to Windows 8 so I could keep my apps. The jump from 7 to 8.1 would otherwise migrate my personal files, but not programs and require a lot of time to reinstall all. This was completely avoided by going to Windows 8 first.
Thanks, again, and very much appreciate the work that you do here.
Best,
G.

HT4818 I want to have an exFAT parition in addition to the Mac OS X and Windows partition. If I create it before running BootCamp, it wants me to delete it. If I create it in either Windows or Mac OS X afterwards, I can no longer dual boot.

I want to have an exFAT parition in addition to the Mac OS X and Windows partition. If I create it before running BootCamp, BootCamp wants me to delete it before continuing. If I create it in either Windows or Mac OS X after running BootCamp and installing both OSes, I can no longer dual boot. What is the magic sequence to get this to work?

I've got the same quandary.
After upgrading my hard drive to a Momentus XT Hybrid and doing a clean install of Mountain Lion, I was surprised that I couldn't format partitions separately and then restore from my clone of the old Windows 7 Partition. I found that I had to use the BootCamp Assistant to manage it all, which essentially meant getting rid of the partitions and starting again...
I now can't get my Windows / BootCamp partition to boot, after adding a 3rd, ExFat, partition, when it was working perfectly fine before. I just get a lot of dos booting failures and a final message that "No boot device is available, press Enter to continue".
See the attached message, that I get when trying to boot the bootcamp partition, through Parallels 7; which also worked perfectly fine before.
Be good to know if there is a work around this in Mountain Lion as, if not, I'm thinking I might skip Bootcamp altogether and just install a machine drive via Parallels. As suggested here:
http://forums.macrumors.com/showthread.php?t=1420754
I might even keep the virtual windows machine on a separate hard drive and then I'll have no need for the ExFat partitions altogether as that was designated for sharing between Windows and Mac.

How to increase Boot Camp partition without harming both Mac and Windows partition

Hello Apple Support Communities.
I have made a Boot Camp partition with my Mac partition, but the problem is that I am running out of space on my Windows partition. (Darn you, Steam Summer Sale! )
Anyways, is there any way to increase the space on my Windows partition without harming both Mac and Windows partitions. I would prefer if I didn't need to delete the Windows Partition and do everything all over again, as I need to download and set up everything all over again. I also know that changing the Windows partition is a tricky and hard thing, and one step can harm my whole computer, but I think that it is worth the risk.
I really don't care how to do it, anything, from a bootable program, to anything. I just want to know how to do it.
So is there any way that I can increase the Windows partition of my Mac without harming both Mac and Windows partitions? Thanks.

This cannot be done using Boot Camp Assistant. But, you can try using Paragon Camptune X for Mac® – How it works.

IPod and Windows Partition

Hello,
I've recently purchased the latest generation MacBook with a 4th generation iPod Nano. A couple of weeks ago I had my iPod connected to the MacBook while it was running Boot Camp (on Windows XP Service Pack 2) and soon after this I noticed that my iPod said that it had no songs. I opened iTunes (on the Mac partition) to find that all the data that was once songs is now listed as "Other". After no luck with getting it to work, I chose to restore the iPod back to factory settings, but the problem still persisted. Whenever I added a song to the iPod, it would show up in iTunes on the iPod as a song, but as soon as I disconnected, the iPod would say that it had no songs, and when I reconnected, iTunes couldn't detect any songs on it.
Since then, I have tried reverting iTunes to an earlier version (as I installed iTunes 8.1 around the same time as this and thought that this may have been the problem), restoring the iPod multiple times, and eventually used Disk Utility to erase the iPod to see if that would help. I've also been looking on many forums where users have had some similar problems and tried their fixes, but none have worked.
I came across this article (http://support.apple.com/kb/TS1493) today which suggested changing the Drive Letter on the Windows side, which I did and changed the iPod from 'E' to 'I', and then my flash drive which was listed as the 'G' drive is no longer detected on either the Mac or Windows partition. I also ran a "Hotfix" .exe file from the Microsoft site that the support article was linking to, which didn't appear to help either. As far as I know, there is no other device that has an 'I' Drive letter (sorry I don't know much about Windows as I've been using Mac all my life).
So if someone could help me out or point me to a relevant link, it would be much appreciated.
Thanks very much

...Anyone have any ideas at all?

OS X and Windows partitions won't appear

I created a 60 gig partition for Windows 7 in boot camp a few weeks ago. Today, I decided to erase the Windows partition, split it in two, and install Windows 7 on one and Windows XP on the other. Windows XP installed fine, but now the other partitions won't show up in the boot screen, or in target disc mode. Are they just lost now?

Did you erase the partition with bootcamp before creating the other 2?

Time machine and Windows Partition

Will Time Machine backup my windows/Boot Camp partition?

i am using time machine and vm fusion. If time machine backs up my entire mac HD, is it backing up my windows data saved on the windows/fusion partition?
Welcome to the Apple forum.
Fusion is something quite different from BootCamp. Naturally fusion or VPC or any other virtual system will be backed up along with Leopard, We are talking about a separate OS in its own partition, and the answer as already noted is no, TM will not backup the Windows partition.

IMac running slow and windows partition not showing

I have an iMac 12.1, 2.5 ghz, i5, 4 gb ram, 500 gb hd (41 gb used) running 10.7.4. We installed windows parallel and windows 7 about three months ago. We rarely used windows and now windows doesn't work, although the icons are there. I tried to uninstall via boot camp and the partition does not show. The iMac is now running extremely slow except when running in safe mode.
How can I delete or reinstall windows and speed up the iMac?
Thank you

Open Console in Utilities & see if there are any clues or repeating messages when you try to launch Parrallels Desktop.
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitiion & use Disk Utility from there to Repair the Disk, then Permissions.

HT6114 Is anyone else having problems with connecting to projectors on the OS X and windows partitions after this update?

I am using the thunderbolt port with an adapter for hdmi connecting to a 42" RCA tv from my mid 2012 MacBook Pro 15". I have confirmed that the adapter and the hdmi cable are perfectly fine. I can only connect to a projector on the OS X 10.92 if I keep the displays separate. As soon as I try to use the mirror feature I lose the visual feed. Sound will still go through however.
On my Windows 7 partition the OS can't even detect it is connected to an external display.

Setting up bootable mac partition and windows partition

I have a 250GB portable harddisk (USB 2.0 and Firewire connections available). I've allocated 150GB for a bootable OSX partition using firewire which works very well.
How can I use the remaining 100GB for backing up my Windows PC data?

If I partition the portable harddisk as FAT32, then I cannot install OSX into that harddisk.
MacDrive is one possibility. The other solution is to get another portable harddisk for backing up my PC data. I was hoping to use one portable harddisk instead of two.

Yosemite and Bootcamp Windows 7 booting problem

Hello all,
I upgraded to Yosemite from Mavericks from the App store on a MBP 2013 late which also had windows 7 installed on it using bootcamp.
I can boot into Yosemite and Windows 7 by going to start up disk and selecting the OS and then restarting but what I cannot do is use the option key to show me the boot disk options when I power on like how I used to do before the upgrade.
Is it the same for all, is there any work around or am I doing something wrong here ?
Thanks in advance.
Priyank.

What about booting into safe mode and then uninstalling the app?

Need help urgently with OS X and Windows 7

I need help urgently.
I installed Windows 7 on my macbook pro with OS X Lion. After installing Windows7, I accidently converted the basic volumes to dynamic volumes and now i can't even boot to OS X.
Please help me how to recover my OS X Lion. If I have to delete Windows and bootcamp partitions, it is OK.
I just want to get back my OS X bootable.
Thanks

I can't even see the OS X partition when I hold down the "Option" key.
I could see OS X and Windows partitions if I hold down Option key before changing the partitions to Dynamic partitions from Basic in Windows 7.
Now can't see OS X partiton and only see Winodws partition but when I tried to boot onto Windows7 , I got BSOD and macbook pro restart.
Please help
The usual reason for the OSX partition to be invisible under these circumstances is that it has been trashed by Windows.
Do you have a backup?

Windows partition boots to Mac OS through startup disk.

In the startup disk window, both my mac and windows partitions are visible. However, both list the Mac OS. Choosing the windows partition boots into the Mac side. I am still able to boot into windows using the option key at start up. How can I change the startup disk OS to get the windows partition in the start up disk to boot to windows?

Sharing my mp3 folder between Mac and PC partitions

Hello,
I'm a Mac newbie considering Bootcamp on a new MacBook Pro. I'm wondering what's the best way to share a folder of mp3's (about 10 GB) between my Mac and Windows partitions. I read that Fat32 partitions can be shared but they are very wasteful of disk space. What's the alternative and is it reliable? Thanks in advance!

I use MacDrive to enable Windows to see the Mac partition. Then you can tell iTunes not to copy the songs when added. I think you can even copy the iTunes Music Library.xml from the mac side

If I install VM Fusion or Parallels, does Windows run all the time? How does that affect computer performance? and how much do I need to worry about hard drive corruption?
Current versions of Fusion and Parallels are compatible with Yosemite. Both are applications which you only run when you want to run Windows within them. As such, there's no effect on computer performance when they're not in use. Like any other software, there is some additional load on your Mac when both Windows and the Mac OS are running together, but any noticeable effect depends on what each is being expected to do and what resources (e.g. available RAM and the number of CPU cores) you can devote to each.
I think there's less chance of HD corruption with a VM than there is with running Windows natively on the Mac in Boot Camp. Consider that, with a VM, you can create Snapshots of the state of your VM at a given time, and then, if something goes wrong (virus, malware, software installations), you can simply restore the Snapshot in a matter of seconds and eliminate the problems in the process. Moreover you can make a backup copy of the entire VM file, and replace a later version if you wish. Also consider that you can assign, say, 100GB of HD space to the VM, but the actual space devoted to the VM is only what's actually used; as more is needed, more is made available and Windows can't tell the difference. So, for example, my Win 7 Pro VM has an 80 GB virtual HD but only takes up 45 GB on my SSD, and that's with XP Mode in VPC installed inside it.
Microsoft no longer supports XP, though virus signature updates are still being issued. But MS has installed a pop-up message about EOL that won't go away (it's installed with KB2934207). Even if you remove that KB in Add and Remove Software, the pop-up continues. But if you have a Snapshot or a backup which is prior to it's original installation, you can skip installing KB2934207, and suppress it's reappearance on a Software Update list.
