5 GB showing in OS X, only 1.98 gigs showing in Windows XP boot camp.

Hey guys,
I know XP has a limit of 4 gigs but I would love to have those extra 2 gigs available in Windows. Any idea's?

Run the 64-bit version of Vista (or XP if there is one.) Or you can try this from Microsoft:
Windows XP Professional and Windows Server 2003 Memory Support. The maximum amount of memory that can be supported on Windows XP Professional and Windows Server 2003 is also 4 GB. However, Windows Server 2003, Enterprise Edition supports 32 GB of physical RAM and Windows Server 2003, Datacenter Edition supports 64 GB of physical RAM using the PAE feature.
The virtual address space of processes and applications is still limited to 2 GB unless the /3GB switch is used in the Boot.ini file. When the physical RAM in the system exceeds 16 GB and the /3GB switch is used, the operating system will ignore the additional RAM until the /3GB switch is removed. This is because of the increased size of the kernel required to support more Page Table Entries. The assumption is made that the administrator would rather not lose the /3GB functionality silently and automatically; therefore, this requires the administrator to explicitly change this setting.
The /3GB switch allocates 3 GB of virtual address space to an application that uses IMAGEFILE_LARGE_ADDRESSAWARE in the process header. This switch allows applications to address 1 GB of additional virtual address space above 2 GB.
The virtual address space of processes and applications is still limited to 2 GB, unless the /3GB switch is used in the Boot.ini file. The following example shows how to add the /3GB parameter in the Boot.ini file to enable application memory tuning:
\[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
\[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="????" /3GB
Note: "????" in the previous example can be the programmatic name of any of the following operating system versions:
Windows XP Professional
Windows Server 2003
Windows Server 2003, Enterprise Edition
Windows Server 2003, Datacenter Edition
Windows 2000 Advanced Server
Windows 2000 Datacenter Server
Windows NT Server 4.0, Enterprise Edition

Windows Vista Boot camp will not show video card

Hello
Im running a macbook pro in windows vista 32 bit boot camp mode. Every thing works fine except that the device manager only shows the VGA adapter and not the Nvidia Geforce 8600M GT I have equiped. I cant find any drivers for this card. Is there any way to get Vista to use it properly?
Thanks

Windows 7 Boot Camp partition doesn't show in the System Preferences.

Hi,
I'm running an up to date 10.6.2 on my OS X partition and Windows 7 x64 on my boot camp partition. When I looked at the start up disk preference pane the windows 7 installation didn't show. Is this normal? 32bit XP always showed in the past. If not, what should I do to fix it? I know that I can boot into windows by holding down the alt key on boot but I would like to know this is working correctly.
Any help would be greatly appreciated.

Make sure that you have a good install of the Apple drivers (boot camp 3.x) in Windows and that Boot Camp Control Panel there works so that you can set the default OS to either, and that it works.
But yes, someone else mentioned the same problem or bug.
The only cause I've seen in the past was where Mac OS X had an NTFS driver and control panel (Paragon, MacFUSE, etc) and you had to use their control panel in OS X.

Windows startup disk not showing up after the boot camp is done partitioning.

OK, Boot Camp finished making a partition for windows on my SSD (I gave it 30GB), and it restarded my computer. I pressed the alt key so i could chosse the windows drive so i could begin the installation, BUT the option to open the windows drive was not there! The only otions I had was to startup from Mac OSX, Recovery Disk and a USB Flash drive Named Windows(I tried it previously but it didnt work because it didnt detect my mouse or keyboard). I the booted up from mac so i could make sure that the partition was created and it was. When i went on startup disk preferences on System Preferences the computer couldent detect a Boot Camp drive only the main Macintosh HD. What am I supposed to do?
I am using a Macbook Pro late 2013 13"
(excuse my English as it is not my first language)
EDIT: I do not have NTFS 3G or a similar program installed.

a few things
what is your exact model mac? which windows are you trying to install?
i'm a fan of small windows partitions, but 30gb is too small unless you're absolutely sure that you will not use any major data consuming apps like music, video or gaming. also, you will HAVE to disable hibernation and the pagefile (google). the smallest we run is 35gb with 40gb being much better
does your mac have an internal optical drive? if so, you need to burn your windows iso onto a physical disc unless the newer 2013 macs let you usb install, which would be news to me
use only a usb2 flash drive

Macintosh HD not showing in after making partion of windows via boot camp

HI
I have a MacBook Pro 2012
recnently made windows 8.1 partition with bootcamp. Been using it for a week and it was fine
one of my colleague made a partion in the windows OS and we restared the computer and press the alt button to choose the OS and now it only shows Windows oS. The Macintosh and the recovery icon has disappeared.
Tried to format the MacBook as they are not any important files. So went to disk utility by holding Command+R. And the in the disk utility It cannot detect the Macintosh Disk !!
any idea what is wrong.???

What exactly do you see in disk utilities? Do you see a main drive,such as 250 GB toshiba and then the windows partition slightly indented. Or only the windows drive? If you still have the main drive showing, you can click on it and erase it . Then go to partitions and set one partition click option and set it as a GUID partition. Go back set mac os extended journaled and then click apply. Then you can reinstall the operating system and use bootcamp to reinstall windows.

Windows 7 partition doesn't show up on my boot camp assistant

i tried to Windows partition from my Mac and i this is all i get.
what should i do?

Are you trying to use Airplay or a wired HDMI/DVI connection From Windows?
Are the BC drivers installed? You can find them using the matrix at Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support and download/instal them on the Windows side.
According to MacBook Pro (15-inch, Mid 2009) and (15-inch, 2.53 GHz, Mid 2009) - Technical Specifications you have a Mini DP port.
Does your Audio work on the OS X side?

Windows Boot Camp partition not showing up on Startup Disk in Snow Leopard

Dear Fellow Mac Heads,
I have Windows 7 RTM installed as Boot Camp in one partition and Snow Leopard 10.6.1 installed in another. In Windows, the Boot Camp icon shows everything (i.e. Network, Windows 7, and Mac OSX Snow Leopard) so I can switch back and forth as I please. But in Mac OS, the Startup Disk menu under Systems Preferences only shows the Mac partition and Network. Windows 7 is nowhere to be found. I can't even do the OPTION on keyboard boot to get into Windows. I have to shutdown the machine, restart while holding onto OPTION key before all partitions show up. What's wrong with this picture? Is this happening to anyone else? Thanks in advance.

Maybe you are using something like NTFS-3G?
Maybe this thread has something for you...
http://discussions.apple.com/thread.jspa?threadID=2146363&tstart=30
Oh, sorry I just noticed that you have read or posted in that thread, but didn't like the answer?
You get strange results with many 3rd party products. I don't use Bootcamp at all. Parallels 4 works very well with Snow Leopard and none of this booting back and forth hassle. Windows is just for research, use the Mac side for performance.

Re-installed fresh Snow Leopard, Boot camp boots,but wont show on startup..

Ok, I had Boot Camp on my iMac with Snow Leopard fine. I decided to reinstall Snow Leopard fresh.
Chose the Mac HDD partition, it re-installed fine. I then thought I'd have to do the Boot Camp again, but I held don "alt" key and Boot Camp boots fine and works.
So I normally have the Boot Camp to boot 1st, as wife and kids use Windows. However I go into Boot Camp on Mac OS, and it doesn't show the boot camp startup disk. Where's it gone?
As I say everything is fine, apart from it now looks like its lost track of the Boot Camp partition.
Is there anyway I can get it back? I ran Boot Camp wizard on Mac, but it either wants to create a new Boot Camp partition, or run windows installer, both which I dont want.
Any help please
chers

Set the default startup disk in Windows.
There is no Boot Camp on Mac OS ("go into Boot Camp"?)
Try:
System Preferences / Startup Disk
On Windows, the Boot Camp Control Panel to used set the default OS
Wizard: by this assume Boot Camp Assistant, which is only a partitioning tool.
Boot Camp doesn't "boot," Windows boots.
Boot Camp - Assistant to create a partition
Boot Camp - Set of drivers and services
Boot Camp - Control panel in Windows to set default boot OS (Mac OS X volumes or Windows, with some other features for laptops I believe)
Personally, too many things use the same name and lead to misunderstandings.

Boot camp wont show the option for installing via iso file

version 5.0.2(462)
the boot camp doesnt show the option to install the windows via iso file
i wanna install windows 7 via an iso file
plz help me as soon as possible

That option is only available for Macs without a built-in SuperDrive (the MacBook Air, Mid 2011 and newer Mac minis, the Late 2012 iMac, and the MacBook Pro with Retina display).
If you haven't got one of those computers and Boot Camp Assistant doesn't show the option to install Windows 7 from a ISO file, your Mac doesn't support the Windows installation from a USB because it's restricted by firmware to a Mac without a SuperDrive. In this case, you have to buy Windows 7 on a DVD from eBay or Amazon, and use it to install Windows through Boot Camp.
If you still wants to install Windows from a ISO file, the only option is to install it on a virtual machine, using an application like Parallels, VMware Fusion or VirtualBox

AMD Radeon HD 6750 isn't showing on Windows Device Manager. Help pls?

Hi Guys,
I am a noob to this, hence appreciate some help here.
I have installed Windows 7-32bit using either Parallels Desktop and VMware Fusion with hope to run some latest Windows games like BF3. Unfortunately, the Display Adapter in Device Manager isn't showing AMD Radeon HD 6750 (unlike many of you here in this forum) but Intel Graphics (WDDM). When the game launch, it draws on the Intel Graphics instead of the AMD Radeon's and make it unplayable. Please advise what I've done incorrectly and what should I do, thanks a lot!
Thanks and regards

If you want to play Windows-based games on your Mac, install Windows via Boot Camp rather than try to run your games in a virtual machine. When you do the latter, your Mac's hardware resources are divided between the two operating systems, and Windows doesn't have full access to or control over the hardware. That will make Windows games run poorly or not at all. When you boot into Windows, only Windows is running, and it can use all your Mac's hardware to run your games.

Is anybody else struggling with an intermittent connection when using the Magic Mouse/Trackpad ONLY on Boot Camp?

Hi,
I've seen thousands of posts about Bluetooth connection issues and interference and stutter/lag for both the Magic Mouse and Trackpad (affecting both Mac OS X and Windows under Boot Camp) but my problem is different.
To summarise my setup, I use:
- Retina MacBook Pro (lid closed or open, doesn't make a difference to this problem)
- Thunderbolt Display
- Wireless Keyboard
- Magic Trackpad (have also tried a Magic Mouse and experience similar issues to the Trackpad)
And in Mac OS X, everything works perfectly. The keyboard and trackpad work smoothly when I'm 6-7 metres from the machine, whether or not the laptop lid is open or closed, and whether or not the Thunderbold Display is connected.
But on to my problem: the bluetooth connection is incredibly unreliable/intermittent when in Windows (I run Windows 7 64-bit and Boot Camp 4.0, and got both devices connected without any trouble via Bluetooth).
But during usage, the cursor stutters/lags frequently, and tap to click (when enabled) seems to get triggered by mistake all the time (even when I'm not touching the Trackpad or even at the computer, clicks get registered).
The Wireless Keyboard is perfect, and works well 5 metres from the machine. The Mouse and Trackpad, though, don't even work reliably when they are 6 inches from the machine. The built-in trackpad on the laptop works perfectly too, in Windows and Mac.
I spent a week assuming I was suffering from Bluetooth interference, so I tried:
- using the laptop with the lid open
- removing the Thunderbolt display completely and trying the Magic Trackpad
- repositioning items on my desk
- disabling wifi
All of these adjustments made minor differences to how good/bad the Trackpad was, but none came close to fixing the problem or making it work as smoothly as under Mac OS X. It was only after doing all of this that I realised perhaps it was just a Apple driver for Windows issue, so I booted into Mac OS X and tested everything out, and sure enough, it's all perfect. But back into Windows, the Trackpad doesn't work reliably at all.
Obviously, the hardware is not at fault, and I assume the signal strength doesn't vary between operating system (why would it?) so I'm left believing this must be a driver issue. The TrackPad and Magic Mouse drivers have been out for a couple of years, so I'm surprised they can still be this bad. I tried both the latest driver from Boot Camp 4.0 (3.2.0.0) for the Trackpad, and also the older one from Boot Camp 3.2 (3.1.0.7) and both are equally bad for me.
So my question is: has anybody else struggled with using the Trackpad (or Magic Mouse) with Boot Camp 4.0 and Windows 7 64-bit, whilst finding it to be perfect under Mac OS? I haven't found many posts complaining about the Windows driver, which is why I assumed it was an interference issue. But I'm almost sure it isn't, having spent 2 weeks investigating.
Any thoughts/suggestions/answers much appreciated!

SOLVED!
After much testing, I have found the cause of lagging/jumpiness on the Bluetooth Magic Mouse and Magic TrackPad in Boot Camp. Hopefully this will help others:
The drivers for the Broadcom 802.11n Wireless Adapter have a setting called "Bluetooth Collaboration" that is Disabled by default. Enabling this option removes the problem instantly. My Magic Trackpad now works flawlessly, even if I stand 6 metres from the machine. It now works just as well as under Mac OS. The setting can be found under:
Control Panel > Device Manager > Network Adapters > Broadcom 802.11n Network Adapter (right click and choose "Properties". Under the "Advanced" tab, highlight the setting named "Bluetooth Collaboration", then change it to Enable. Then click OK.
I narrowed the problem down to the wireless card by disabling ALL startup services and processes for Windows, then re-enabling one by one. As soon as I enabled the Windows Wireless Service, the problem came back. Similarly, disabling the Wireless Card inside the Network and Sharing Center (or Device Manager) removes the problem. This led me to believe it must be a driver issue with the wireless card, since the problem didn't occur with the Magic TrackPad under Mac OS, or on my mother's Windows 7 64-bit computer. So when I went into the Driver Properties to check for an update, I found this setting about Bluetooth Collaboration.
I really hope this helps others trying to use Bluetooth devices under Boot Camp. All Apple notebooks use the Broadcom card (and have done for years), so this driver is installed for almost anybody using Boot Camp on an Apple notebook. I'd assume this problem would affect anybody using Boot Camp + wifi + a Bluetooth device.
Cheers

HT1461 Can one use boot camp to play computer games normally only found for PCs?

I have some older computer games, specifically Warhammer 40k rts games, that I woud still like to play and was curious if boot camp would allow me to play those on my mac? Also, if it is possible am I putting my computer at risk in any way? I'd like to play them but not so badly that I would be damaging my mac pro or shortening its lifespan. There dont appear to be any emulators out there currently so I'm checking here to see if anyone knows anything.

Yes. There are several ways to run Windows on the Mac:
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
   1. Install the Apple Boot Camp software. Purchase Windows
         XP w/Service Pak2, Vista, or Windows 7. For Boot Camp
         4.0 and above you can only use Windows 7 or later. Follow
         instructions in the Boot Camp documentation on
         installation of Boot Camp, creating Driver CD, and
         installing Windows. Boot Camp enables you to boot the
         computer into OS X or Windows.
     2. Parallels Desktop for Mac and Windows XP, Vista Business,
         Vista Ultimate, or Windows 7. Parallels is software
         virtualization that enables running Windows concurrently
         with OS X.
     3. VM Fusion and Windows XP, Vista Business, Vista Ultimate,
         or Windows 7. VM Fusion is software virtualization that
         enables running Windows concurrently with OS X.
     4. CrossOver which enables running many Windows
         applications without having to install Windows. The
         Windows applications can run concurrently with OS X.
     5. VirtualBox is an Open Source freeware virtual machine such
         as VM Fusion and Parallels that was developed by Solaris.
         It is not as fully developed for the Mac as Parallels and VM
         Fusion.
Note that VirtualBox, Parallels, and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech Labs- Virtualization Benchmarks, January 2013 | MacTech for comparisons of Boot Camp, Parallels, and VM Fusion. Benchmarks of all of the above except Crossover can be found in Benchmarking Parallels, Fusion, and VirtualBox Against Boot Camp - The Mac Observer. Boot Camp is only available with Leopard or later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

Is it possible to use boot camp to install windows xp from only an update disk?

Hello,
I have recently come across some of my old windows applications and an update disk for windows xp sp1. All I have is the update disk and I partitioned my drive and booted into the CD. Whenever I got through some of the processes of the initial install it said that I had an update disk and prompted me to first install an earlier version of windows (in this case I do not own one). Is there anyway that I could bypass this part of setup and install windows using this disk (like I have on PCs with no operating system installed) or do I need to go out and purchase a copy. If there is anyway that you could help it would be appreciated very much because the way the economy is these days I would like to save a couple bucks here or there. Especially putting money to a company like Microsoft....it wouldn't suit my fancy. :D

Ok, so officially, you have to install it on your Mac's internal drive. Good, thanks for clearing that up.
I guess the only simple alternative to installing Windows on your Mac's internal drive is to buy another Mac, and install it on there instead I mean, you could have a Mac Mini or a MacBook, and have that running Windows under Boot Camp.

OS X not showing up in boot camp control panel

Hi, I am using mac book pro with OS X mavericks. Recently I installed windows 8.1 with boot camp assistant. It was all running fine. I partitioned my windows 8.1 drive to a new volume. When I did this,my OS X disappeared in bootcamp control panel. It not showing up in the list of OS's when we boot the machine. any help would be appreciated. Thanks.

If you are not seeing the OS X partition while holding down the option/alt key during a restart, it appears your Boot Camp installation damaged the OS X partition, which is probably why it is not showing up in the Boot Camp control panel.
Do a backup. Boot to the Recovery Volume (command - R on a restart or hold down the option key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then select the Macintosh HD partition and re-install the OS.

IMac used as PC only through Boot Camp

Crazy question on behalf of a friend of mine who loves the form factor of the iMac, but is unfortunately completely reliant on Windows applications for his profession:
Has anyone used an iMac as basically a PC only...utilizing Boot Camp? Is there any downside to this? Apple hardware (especially in the all-in-one category) seems so much better than similar PC hardware. But I'm wondering if planning to completely relegate an iMac to being just a Windows box is a crazy idea. Any opinions appreciated.

Windows 7 on iMac Late 2009 graphic fix:
Installing graphic drivers on iMac
iMac and ATI graphics with Windows is a PITA and real issue.
There are work around solutions people came up with.
Is a Mac OS better? I don't see it that way at all.
That's why I now use and built two PCs and turned Mac Pro into Windows 7.
Is a PC or a Mac better when it comes to Windows? No. Much better and easier to run Windows on PC hardware. Really.
Windows 7 support for Core i-family of processors is a step ahead.
OS X is so tightly tied to hardware, that can work against you.
And Apple doesn't keep Windows drivers (Boot Camp) updated.

5 GB showing in OS X, only 1.98 gigs showing in Windows XP boot camp.
