Windows 8 crashes in boot camp.... bad pool header

I continuously am forced to reboot window's 8 in bootcamp due to a blue screen. The majority of time the error states "Bad_pool_header" but there are times when it is another message.

I would point out as I did above:
I also installed the Boot Camp special hardware.
you are running Windows.
Boot Camp (Assistant) partitions the drive, and in Lion downloads Windows Support software.
Lion 10.7.4 w/ Boot Camp 4.01 is the better choce.
With Windows you will always be on your own and need to update drivers.
Apple isn't going to until after 8 is either released or is finalized, and maybe only for Mountain Lion (guess based on past)

I can't start windows 7 normally from Boot Camp

I can't start windows 7 normally from Boot Camp.
It was running fine since I have installed it 7 months ago, but now it can't start or (restart) normally (safe mode is ok). It displays a black screen after showing the logo, and I have to shut down the machine. My Mac system is working fine. Mac technician (Genius Bar) has run a surface scan to verify hd integrity and proofed ok, but could not give any advice on Windows issues.
Please advice if anything I should do before cleaning up my partition and reinstall Windows.

I would guess and sorry for asking but you already tried booting from Windows 7 DVD and doing auto repair?
There are dozens of things to look at and do, and begin with chkdsk in Windows, yes but that only looks at one aspect. You can't really check for bad sectors on a drive's sectors. The best? to use the drive vendor's own utility actually, often with a linux boot CD or Windows program (they don't make Mac OS versions, one reason I first installed Vista over 5 yrs ago)
Restore check points
Uninstall last update or driver
Clean the system of debris temp files, caches, registry errors, fonts and left overs
make sure you have 20% and 12GB free space or more
A hard shutdown can create more problems.

CS6 (64 bit) crashes 'Bad Pool Header'

Hi All,
I just installed Photoshop CS6 International English and the 13_0_1_1 update.
Bridge standard and 64 bit both work. CS6 standard works. CS6 64 bit crashes with a blue screen 'Bad Pool Header'.
I reinstalled CS6 and the update. No change.
Windows and all drivers are up to date.
I have been using Photoshop for many years - starting with v 6. I have been using CS5 64 bit on this system since it came out with no problems. CS5 64 bit is still working with CS6 installed.
CS6 64 bit is the only program to have ever given me this error on any computer I have ever had.
Custom built system:
Asus motherboard M4A78-e
AMD Phenom 9950 quad 2.61 GHz
8 GB 1066 MHz Corsair ram
Ati Radeon Sapphire Vapor-X HD4890 1GB memory
Enermax Revolution 85+ power supply
Zalman CPU 9950 fan
Lian-Li PC60FN case
Windows xp professional x64 service pack 2.
Thank you for taking the time to read about my problem and thank you in advance for any suggestions.

Dear Mylenium,
I can see from your profile you have been very active on this forum for many years and have undoubtedly helped too many people to count. However, your certainty and negativity belies my experience, both with CS 5 64 bit and with CS 6 Bridge 64 bit, as you can see from my initial post.
I took your suggestion and opened the Event Viewer. There were no logs to read. I looked in the properties of each of the log types in the events window and went to windows\system32\config\ just to be sure. Is there anything I can do to trigger creatitng an event log or should I look to finding the info in some other way or place?
Thank you for taking the time to respond.

Lion - Windows XP (SP3) with Boot Camp

Hi, I have a MacBook Pro with Lion on it and would like to install Windows XP (SP3) with Boot Camp, but the instructions only mention Windows 7... do I need to buy Windows 7 or can I run Windows XP anyway?

that would be a costly option... I got 4 giga and will stick to it, I mainly use 2D, but 3D from time to time too... that's why I thought about boot camp rather than Parallels. Will try to get Windows 7 unless you think it's a bad idea.... By the way, how much space would you allow the partition for windows?
Not really costly at all, 8GB of RAM is currently $51 from www.macsales.com (OWC) and Fusion is $49 retail so for $100 you have an elegant solution. Much less expensive than buying WIndows 7.
Also you can partition as much space as you want, how much you need is 100% dependent on how much you use.

Can windows 8.1 in boot Camp display in target display mode on an IMac?

I have given up on Windows 7 running in Boot Camp on my 15" MacBook Pro and displaying it on my 27" IMac via thunderbolt and Target Display Mode.
The FAQ concerning Target Dsiplay Mode farily clearly says Windows 7 won't work.
But it does not say Windows 8.1 will or will not drive Target Display Mode via thunderbolt.
see: http://support.apple.com/kb/HT5219, question 29
Has anyone found that running Windows 8.1 in BootCamp on a MacBook Pro Retina mid 2012 will display via a thunderbolt cable in to Target Display Mode on a late 2013 IMac 27"?
I don't want to go to the trouble of installing Windows 8.1 and trashing my otherwise functional Windows 7 Boot Camp installation unless it is going to display properly on my late 2013 27" IMac running OSX 10.9.3 via thunderbolt.
Thanks in advance!

no, tdm doesn't work under bootcamp regardless of which windows is being used, imho i don't think it will ever work under bootcamp

Problems with Windows XP SP3 in Boot Camp

Hi,
I have recently received a 21.5" iMac; it is the higher-end of the 21.5" standard configurations. The problems I am having, I believe, specifically relate to drivers.
Firstly, I get no sound whatsoever in Windows XP SP3 (boot camp); I have tried removing and reinstalling the drivers from the Snow Leopard install disc, but no success. I have no yellow question marks in the device manager window, but the absence of audio still persists.
Secondly, I cannot gain access to the special functions of the Apple wireless keyboard in Windows XP SP3 via Boot Camp. Again, I have tried reinstalling the drivers, but no success. I have read an Apple support document which states that the keys are only supported on late 2009 Macs; I own one of these Macs, so that cannot be the problem.

Boot Camp forums are here: http://discussions.apple.com/category.jspa?categoryID=237

I have a copy of Windows 7, and I am trying to bring up Boot Camp on my MacBook with Snow Leopard. But my Snow Leopard install disk is too old for Windows 7, so attempted Boot Camp install of drivers fails.

I have hand-installed the NVidia graphics driver, and I have keyboard, minimal trackpad, and hardwire to internet all working. So the WIndows machine is usable. But I am hurting for wi-fi, better trackpad, and whatever else is delivered by Boot Camp. I can't use any of the Boot Camp upgrades because I do not have XP or Vista.

While we all have MacBooks in this forum not all of us use Boot Camp. There's a Boot Camp Support Community where everybody uses Boot Camp. You should also post this question there.

I bought macbook pro at cash america used and loaded with windows 7 ultimate by boot camp.My questions is it has mountain lion loaded but original ower has name with password so how can I reload so I can sign on as administrator for downloads and upgrades

I bought a 13 inch macbook pro9.2 at Cash America with windows 7 Ultimate with boot camp program.
The Mac op sytem has Mountain Lion installed but the previous ower has his name and password attached to it and can only use as guest.
My question is how do I get around this to be administrator to reload software so i can use mountain Lion,and not loose the windows op .

If you reformat the partition that contain Mountain Lion and reinstall Mountain Lion, it should not effect the Windows pratition.
Have said that I suggest you backup everything you might want to save just in case.

Windows Update on Windows 7 (x64) on boot camp fails

Running Windows 7 x64 on Boot Camp and trying to install an "important" update from windows update, but it fails:
Update for Windows 7 for x64-based Systems (KB2506014) - Published: 4/12/2011.
I received error code 80073712 and ran System Update Readiness Tool to no avail. Microsoft recommends repairing Windows from the install disc if using that tool fails, but I'm not willing to go that far just yet.
KB 2506014 title is "Update for the Windows Operating System Loader", so I am wondering if there is something about how Boot Camp is configured that is preventing this from installing.
Has anyone else running Windows 7 x64 on Boot Camp received the same error for this particular update, or been successful in installing it? It is thus far the only windows update that has failed to install for me.

I uninstall bootcamp wireless etc. drivers such as broadcom, bluetooth that I do not use on Mac Pro.
There are some utilities not compatible with Windows 7 which you do not want to use.

How can I force mount a dvd that isn't even seen by Disk Utility? I can see it on the Mac when using my Windows 7 partition via Boot Camp, but not in Lion, which is how I would rather be running.

Well if there is a EFI block, then running a program in OS X isn't going to do a lick of good.
After all EFI was designed for Trusted Computing and Digital Rights Management, to act between the OS and hardware, can read drives, contact the Internet and everything.
Windows doesn't use EFI, will have UEFI in Windows 8 though.

Install Windows 8.1 with Boot Camp

Greetings you all,
I've been trying to install WIndows 8(.1) on my MacBook Pro early 2011, but without any success. I downloaded the .ISO of Windows, stored it on my external HDD, downloaded the software via Boot Camp to host Windows (I'm sorry I'm french so I'll have to translate everything) and put it on another external HDD, and when I plug them to my Mac and start the installation of Windows, it doesn't detect the USB.
What should I do? If possible, avoiding any installation of the disk image on a DVD.
Thanks.

There are several possibilities.
1. You do not have contiguous free disk space.
2. BCA has failed, or you may have a Fusion drive which is causing problems.
3. You have incorrect permissions on the disk.
4. Can you boot in OS X Safe Mode - OS X: What is Safe Boot, Safe Mode? - Apple Support?

Can't install windows 8.1 with boot camp

I'm trying to install windows 8.1 with boot camp and this is the message I keep getting. I've tried several times and every time I get this. I have a 2015 MacBook Pro. I've tried installing from a usb with ISO and also from a oem windows dvd. Any help would be appreciated.

Excellent.
Windows installation has four or five reboots, and the Apple BootManager tracks such reboots via the Mac NVRAM, otherwise the next reboot will cause OS X to boot rather than Windows. It is also used to set up some variables used to pass information to the CSM-BIOS layer. If an installation has failed, the variables do not reflect the current and clean state of the machine. A NVRAM reset will re-initialize these variables for the next attempt.
