Cant boot into windows 8 partition after updating to 10.10.3

Hi guys,
You may have heard about this bootcamp issue, where suddenly the windows partition is not shown in the startup-boot-menu.. I've tried several things without success.
The partition is still browsable in the finder of OSX
Please help... !! :/

Can't boot into windows 7 partition after updating to 10.10.3. [MBP-mid 2014]

Storage still shows windows partition but when I long press the option key when the laptop is turned on, it doesn't show the windows partition.

Loner T - I can see that your analysis/advice is working. I have the same problem. Below is my info based on your recommended data collection. What do you suggest? Thanks a lot.

Added third partition and cant boot into Windows.

So I had windows 8.1 bootcamped, and being the idiot i am, created a third partition, messing up my bootcamp. I am unable to boot into Windows now. I suspect my mbr and gpt are out of sync, but do not know how to fix this. By the way, both disk utility and finder show that the bootcamp partition is there, but there is not option to boot into it on the boot selection menu thingy.

Back up your data. Erase then format the drive. Reinstall OSX and Windows.

[SOLVED] Dual boot with Windows 8, problems after updating Windows

Hi all,
I have been maintaining a dual boot of arch and Windows 8 for some time. I recently updated Windows to 8.1, and found that the update process had two side effects:
1) The update added a new partition in the middle of my file table, so my /etc/fstab which referenced "/dev/sda6" was wrong because that partition is now "/dev/sda7."
2) The default boot device was switched to the Windows Boot Loader instead of grub. But, this is not a problem because I can work around this by using the "Choose boot device" feature of my bios at start up.
So, neither of these problems are critical for me at the moment. I can fix my fstab and just press a hotkey at startup.
EDIT: I have avoided the /etc/fstab issue by referencing my partitions using UUID as specified in https://wiki.archlinux.org/index.php/Fstab.
How do I set the default boot device back to grub? There is some weirdness here, I think windows is using UEFI booting and my grub uses the old booting system.

Rex: I tried that command, got some warning messages regarding blocklists, but no dice.
Loqs: You are right about windows using a ESP and UEFI while my linux is not booting using UEFI. My bios is configured to try "Legacy boot" first before trying UEFI. Getting linux to boot using UEFI seemed like a pain, so...
I went into my BIOS settings and found that the Windows Boot Manager boot device was listed in front of my hard disk (which boots linux). I don't think this used to be the case, so something about the update caused my BIOS to reorder the boot devices (probably because the partitions changed).
Switching my hard disk to be above the Windows Boot Manager in the boot device list now makes me boot into linux by default, and I can boot into windows by pressing a hotkey at bootup and selecting the windows boot manager.

Cannot boot to Windows 8.1 after updating to Yosemite

I am using a MacBook Pro (Retina 13-inch Late 2013) computer, and mainly use Windows 8.1 via bootcamp on it for work. I have just updated OS X Maverick to OS X Yosemite 10.10, and now when booting and holding option, the Windows and Backup partition no longer show.
I have read a few threads on here with similar problems, and I believe that I understand the crux of the problem, but I am having difficulties actually using TestDisk as I'm not exactly sure what options to use and what to look for.
Below is a screenshot of my Disk Utility:
And here is the output of TestDisk so far (I analyzed the disk0):
It looks like the Bootcamp partition is still there, but I'm not sure what steps to take next -- any help would be most appreciated!

Can't Access Windows 7 Partition after updating OSX to 10.8.2 - Will I be able to get my data back?

Itys does not appear in the boot list after holding down alt. I can still see it in disk utilities as a 66GB partition but it can't be veriefied or repaired from there. Any assistance in this matter would be greatly appreciated.

You'll still be able to access it unless a problem occurs. Back everything up first.

Can only boot into Windows 7. Can't even boot from Snow Leopard DVD.

I have no idea what prompted this. I don't recall installing any OS updates recently, other than some Windows Live apps in Windows 7.
I have an early 2009 Mac Mini with Snow Leopard, and have Windows 7 64-bit installed in a Boot Camp partition. When I installed Windows 7, I couldn't get the Boot Camp utility to install within Windows (I guess because it's 64-bit) so to switch back and forth between OSes, I just shut down the Mac and restart it with the Option key pressed, and select Mac OS X when I want to return to Mac. This has worked for about a month and a half now (ever since I got Windows 7). Suddenly I have problems.
I first had problems booting into Windows or Mac. I got to the grey screen with the Apple logo, with that spinning "progress" thing going for a while, then it would freeze up and get stuck on the grey screen with the Apple logo. I zapped the PRAM. No help. Then, after disconnecting all external drives (I have several) and extra USB devices, I was able to boot from the DVD install disk and reinstall Snow Leopard on my internal drive. Joy, or so I thought. Then I booted into Windows 7, and after some weirdness getting it to start, it did successfully start and ran just peachy.
Then I turned off the Mac and held down the option key (as usual) to return to Mac OS. But now all that happens is that I get a grey screen for a few seconds, then the Mac boots back into Windows 7, which seems to work fine. (I'm in Windows 7 right now.) I turned on one my external drives (Snow Leopard installed, connected via Firewire 800) in hopes that the Mac would boot into that, but same thing. Ignored and back to Windows 7.
Then I thought I'd boot from the install DVD again by putting it in the drive and holding down the C key as I restart, but the same thing--a grey screen for a few seconds, and then booting right into Windows 7. I can't seem to escape Windows 7! It's a bit disturbing when it won't even recognize the install DVD.
I tried to call Apple Care since I'm within my 90 day support window, but of course they are closed. I'm figuring that I'm going to have to take this into an Apple Store, but thought I'd see if anyone has any ideas. Any advice will be appreciated. Thanks.

According to Apple, Win 7 64bit is supported with Bootcamp 3.0. If bootcamp 3.0 is available; I could not find it anywhere on Apple's website. It appears the most recent version is 2.2. The only place I could find 3.0 is not on Apples website and it's a questionable source so I won't post it here.
It may just be a matter of time before Apple makes it available. I'm not suggesting you wait, however if the install disk can't be used, I'm not too sure where u could go from there. Calling Applecare might work.
If you do a simple google search using the terms 'download bootcamp drivers windows 7' u will see what I was referring too.
Here's what I found from Apple (It doesn't specifically mention 64bit however just win7): http://support.apple.com/kb/HT3920
This is not from Apple, but specifically addresses whether they support win7 64bit: http://www.macnn.com/articles/09/08/31/boot.camp.win.7.64.support/
Here is more info about bootcamp 3.0 and win7: http://www.apple.com/support/bootcamp/

Can't boot into Windows 8.1 partition after apple store repair

Can't boot into Windows 8.1 partition after apple store repair
I went to the apple store about a week ago to get my screen fixed, and when I get it back I don't have an option to boot into my windows partition. The bootcamp partition is still there, but I can't boot into it. I can still see all of the files on the drive. When I try to boot into windows from the startup disc setting I get "no bootable device — insert boot disk and press any key” on a black screen. I went in for a dead pixel, and the guy at the genius bar ran something on my computer and went into disk utility application. I’m not sure what he was doing, but obviously that’s what messed up my windows partition. How can I be able to boot back into windows? Here's what disk utility looks like on my computer.

Here's the output

Have to restore OS X.9.1 after booting into Windows 7 on Bootcamp

I am having an odd problem--whenever I boot into Windows 7 on bootcamp, when I then boot into Mac OS X.9.1, I have to restore the disk from Time Machine. This has never happened before, but now has happened twice in a row. It takes hours for the Restore function to restore everything. Anyone have any idea as to why this is happening. My MacPro dates to 2010. Thanks.

Windows is a guest on your Mac. If you use Windows tools to change the partition Map, or the size of any partition, all Mac OS X partition information is trashed, and you will need to restore it before proceeding.
Otherwise, you should be able to hold down Alt/Option key at Startup, and select your Mac OS X Volume to boot from (after several minutes of discovering what Volumes are present).

Can't get past gray screen for OS X but will boot into Windows partition.

Hi- I am really desperate for help here.
Restarted my computer this evening when Front Row wasn't able to find the files on my external HD. When it booted it went directly in to my Windows Boot Camp partition. So I restarted, held down 'option', choose my OS X disk and just got the spinning sun icon on the gray screen for several minutes. It then booted into Windows again. If I hold down 'option' again I can cut it off before it gets to Windows.
I've tried booting into a cloned HD via FireWire and same results.
I've tried booting with the install disk (c key held down) and it won't recognize it.
I've tried Safe Mode (shift key) - same.
I've booted into Single User and done fsck and and it says everything is ok.
- BUT I did notice it says further up- "BSD: rootdisk0s2, major 14, minor 2". Are these errors? If so why didn't fsck find and fix them.
I've tried resetting PRAM and SMC.
The only thing I have done out of the ordinary was an hour before I was trying to get some of my files on my wife's laptop and went into permissions on my HD and changed "Everyone" Priviledges to Read (or maybe it was Read and Write) then chose "apply to enclosed items". This change took about 20 minutes.
The computer is, of course, just over a year old and has worked perfectly up until now.
Someone-Please!!!

Tried that and it just doesn't read the disk. I've booted it with the disc already in and held Shift and also tried it with "C". The same for putting the disc in just as it boots up.
I went into Single User mode again and compared the text against what shows up on the laptop. Their are a few differences. At the very beginning of the iMac text there is:
npvhash=4095
hi mem tramps at 0xffe00000
PAE Enabled
64 bit mode enabled
-then-
Extension "com.apple.driver.AppleACPIPlatform" has immediate dependencies on both com.apple.kernel and com.apple.kpicomponents; use only one style.
Extension "com.apple.driver.AppleIntelCPUPowerManagement" has immediate dependencies on both com.apple.kernel and com.apple.kpicomponents; use only one style.
-then- after "MAC Framework successfully initialized" comes this three times...
Extension "com.apple.driver.AppleACPIPlatform" has immediate dependencies on both com.apple.kernel and com.apple.kpicomponents; use only one style.
These are really the only major differences that I can see in the Single Mode screen.
I also have tried booting from the Firewire drive clone on the laptop but it is not an available option for booting. The disk partitions mount but have a lock in the corner and say they cannot be opened because I have insufficient access privileges.

No SATA drive after booting into Windows (BootCamp 5.0)

One of my DVD burners has failed in one of my 2008 Apple Mac Pro's. I pulled the drive out (it was PATA/IDE) and replaced with a new LG WH14NS40 Blu-Ray Burner. I had to pull the fan out (temporarily) and run a new 24" SATA cable (with right-angle connector) from one of the two extra SATA ports (on the motherboard) to the new actual SATA drive, and also install a MOLEX to SATA power connector.
I managed to get the drive installed (and working). I now at least have a Blu-Ray burner in my 2008 Apple Mac Pro (with OS X 10.8.3 Mountain Lion).
The problem seems to be with when I boot directly into Windows 8. When I boot into Windows 8, the two ports on the motherboard are disabled and the latest BootCamp 5.0 drivers don't seem to support the two SATA ports on the motherboard (they seem to be disabled). So when I boot directly into Windows, my LG WH14NS40 Blu-Ray drive disappears.
I really wish Apple would have just "done things right" from the very beginning and took the time to write decent BootCamp 5.0 drivers that supported the two SATA ports on the motherboard, so that users who need to replace their old/dying/aging PATA drives could easily replace them with SATA drives and use the two SATA ports on the motherboard.
Also it would have been nice if Apple would have taken the time to write good BootCamp 5 drivers (for Windows 8) that support booting from the two SATA ports on the 2008 Apple Mac Pro motherboard.
I've heard of many people that have tried installing RAID Controller Cards (from OWC) in their 2008 Apple Mac Pro to upgrade their four hard drive caddys from SATA II (3Gbps) to SATA III (6Gbps) but unfortunately the RAID Controller Cards don't seem to be bootable and the only option is to install a fifth (bootable) hard drive into the Apple Mac Pro and this is normally done by installing a bootable SSD drive into one of the DVD-drive bays. Unfortunately if you use a SATA SSD drive (which most SSD's are SATA) and then use one of the two SATA ports on the motherboard to connect it, then you go back to having the problem of not having a boot drive when you boot directly into Windows 8 (since there are no BootCamp 5 drivers for the 2008 Apple Mac Pro that support the two SATA ports on the 2008 Apple Mac Pro motherboard).
This seems to be a never-ending problem, and we have twelve 2008 Apple Mac Pro's (along with an office full of 2008/2009/2010/2013 Apple Mac Pro's) and we're getting extremely frustrated with Apple's lack of support in BootCamp 5.0 drivers for the 2008 Apple Mac Pro (and the two SATA ports on the mainboard).
Please fix this problem, and please update the BootCamp 5.0/5.1 drivers (for 2008 Apple Mac Pro users) and please support the two SATA ports on the Apple Mac Pro mainboard, and please make those two SATA ports on the motherboard bootable and usable in both Microsoft Windows 8 and in OS X 10.8.3 Mountain Lion. Please update the BootCamp 5.0 drivers to support the two onboard SATA ports in Windows 8 (so that my Blu-Ray burner is viewable/usable in Windows 8).

Just as a follow-up, yes it does seem to be possible to get both SATA ports on a 2008 Apple Mac Pro working (in Windows 8).
You need to enable AHCI in Windows 8.
First boot into Windows 8 and then go into the windows registry (regedit) and enable AHCI in your registry.
You can do this by going to the following registry key:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci
Set the "Start" Value data to "0" (to enable AHCI in Windows).
After AHCI is enabled in Windows, then reboot your computer and now the SATA drive (connected to the ODD port) should appear in Windows (under devices).
Now the next step is to update your AHCI drivers (in Windows) to the latest Intel drivers, so that your SATA device will actually work (and work properly).
The latest Intel RST drivers can be found here: https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=2101&DwnldID=2306 0&ProductFamily=Software+Products&ProductLine=Chipset+Software&ProductProduct=In tel%C2%AE+Rapid+Storage+Technology+(Intel%C2%AE+RST)&lang=eng
Download the 64-bit drivers (if you are running 64-bit Windows).
After you install the latest drivers, and perform a reboot, your SATA drive should now work under windows.
You can find a long detailed thread about enabling AHCI (in Windows 7) here: http://forums.macrumors.com/showthread.php?t=760482
The thread listed above is a bit old/dated (2009?) but it does give detailed step-by-step instructions for those that want to enable AHCI (and get those two onboard SATA ports working in Windows 8 or Windows 7).
I managed to get everything working in Windows 8, and I was able to enable AHCI in Windows 8, installed the latest AHCI drivers and I'm now able to use my SATA Blu-Ray burner in my 2008 Apple Mac Pro.
Hope this helps!

Can I boot into Windows if it is partitioned on a second hard drive?

I want to put my 2009 MBP hard drive into a 2012 MBP by replacing the optical drive with the 2009 hard drive in a caddy. The 2009 has Windows partitioned on it already through bootcamp.
Will I be able to boot into windows through the second drive or will I have to bootcamp the new 2012 drive with Windows?

OK Cool. I think I will try that. Thanks for the tip. I appreciate it.

Trying to boot into Windows with no Windows Partition

So I tried Windows XP on boot camp and ofcourse it says it's not installed when it clearly is >_>
So I restored and when I boot up it tries to boot into windows, when it loads it says Disk Error insert boot disk. When I hold alt it only shows Macinstosh HD.
I've just re-partitioned and restored to Mac full partition again so I need to reboot and see if that works...
Any help?

The last line in your post says "I've just re-partitioned and restored to Mac full partition again so I need to reboot and see if that works"
Rebooting should take you to OSX provided you removed the BC partition correctly (using Boot Camp Assistant)
I am not sure what you mean by the rest of the post "So I restored" restored what?
It sounds as though XP was either not installed or not installed correctly, what happens now when you reboot?

MSI K9A2 Platinum + Phenom 9600 + 2GB Mushkin XP8500 cannot boot into windows

Hi!
I am building my computer using the Spider platform and I ran across problems during booting into windows.
I am using MSI K9A2 platinum with Phenom 9600 and Mushkin 2Gb kit XP8500 ddr2 1066. I have no problem installing windows xp.
The problem starts when I install the utility and drivers that come on a cd from MSI, my computer requests to re-boot after installation and after
that it will not boot into windows. I can get to the windows logo and then the system reboots right away.
I checked the bios and it shows that the ram is running at 800mhz and i have tried running with just 1 stick and im getting the same problem every time.
Anyone knows how to resolve this?
thanks!

Everything is stable now...I guess installing the driver from the MSI website is the best thing to do right now
I notice that my ram is underclocked to 800mhz instead of 1066mhz...I have update the motherboard BIOS to v1.2 and i checked that the ram is running on unganged mode...I tried adjusting the spd to 5-5-4-12 with voltage of 2.2v as suggested by the mushkin ram itself
Any idea?
"I have update the motherboard BIOS to v1.2 and i checked that the ram is running on unganged mode..."
That is the correct mode.
"I notice that my ram is underclocked to 800mhz instead of 1066mhz..."
1066 is not officially certified by JEDEC, also your memory probably don't have SPD configuration for that freq.
Contact to Mushkin for more details.
"I guess installing the driver from the MSI website is the best thing to do right now"
Yep
"Everything is stable now.."
nice :smiley:

Black screen when trying to boot into Windows 7

Hello everyone.
Today we've encountered an issue with one of our MacBook Pros with Windows 7 installed. The computer was booted into Windows 7 (it's strictly used as a Windows machine by this particular user) and after a time of inactivity it went to sleep. It wouldn't wake up from it's sleep so we tried a hard boot. At that point we would get the grey screen, the Apple tone wouldn't sound off and it would just go to a black screen (by default we have it booting to windows). So then we reset the PRAM. Now, we get the apple tone and we can boot into the Mac side. But when we try and boot into Windows, we get a blank screen.
What's even more interesting, if I try and boot into a Windows install disk to do a boot repair, it gives me a black screen. If I even try to boot from a live Linux cd, I get a blank screen! When important thing I then noticed was that the cd spinned for a couple minutes, then stopped. So I began to wonder if it was still loading the OS like expected, but just wasn't displaying it.
So I booted into Windows, got the blank black screen. Then I went into another computer, fired up remote desktop and voila! I'm in the machine!
So the problem is this: When booting into ANYTHING other than OS X, the display turns off.
What can we do?

Hello there,
I have a similar problem! Windows 7 shutdown unexpectedly and since that I can not reboot in windows anymore only with safe mode where everything is a mess.
Also when it's trying to reboot in windows a blue window appears,says something about drivers and it is counting something (79.78...till100)but I m not able to read it cause it disappears immidiately and then black screen and then it turns to reboot in mac which works fine.
I m sorry if I confused you with my english...
If anyone knows please help!
Thanks
