Boot Camp - Upgrade to Windows 8.1

I have installed the upgrade version of Windows 8.1 on my Mac Pro before the instalation of the latetst Boot Camp Assistant and ended up unavaiable to get into the original OS X.
How can I get into the OS X at the starting of the computer ?
Or, can I install new Boot Camp Assistant on the Windows 8.1?

Welcome to Apple Support Communities
Hold the Option (Alt) key while your Mac is starting up until you see all bootable partitions in the display. If you see your OS X partition, choose it. If you want to start up in OS X by default, open System Preferences > Startup Disk, and choose your OS X partition.
If you do not see the OS X partition, you removed it during the Windows installation. If you want to reinstall OS X, you will probably have to format the whole hard drive

I'm getting "Installer disk not found" message during boot camp 5 and windows 8 install on late 2011 MBP upgraded to Mavericks.

hello,
And thank you in advance.
I'm getting "Installer disk not found" message during boot camp 5 and windows 8 install on late 20011 MBP upgraded to OS X 10.9 Mavericks. Any ideas?
I've downloaded the Window support option software and the WindowSetupBox.exe and copied it to the USB drive. I tried to create an iso image from my Windows XP machine but recieved messages that Windows 8.1 could not run on XP. I've ordered the Windows 8.1 backup media.
Any way to proceed?
Thanks Tim

download the win 8 iso from here;

then start over. install on to your usb along with the support software.

Boot Camp problems with Windows 7, and a new Macbook Pro

When I try to install Windows 7, when the process is almost complete and Windows is finalizing all settings, the system reboots then gets stuck at the white/gray bootscreen, and then tries to boot from disk, only to repeat the bootscreen cycle indefinitely. How do I fix this? Thank you very much.

My MAC BOOK is 13 inch, first generation of unibody that I bought when it first came out last November, 2009. It seems that the latest boot camp 3.1 does not support windows7 64 bits on my mac book model. I followed Apple instruction to upgrade boot camp 3.0 when running XP 32 bits. And I then upgrade my XP 32 bits to 64 bit Windows 7. The upgrade/installation was successful but I encountered a lot of problems with the mouse and sound.
1. No sound with my new Windows 7 64 bits.
2. I managed to make Windows 7 64 bit recognize my apple mighty mouse. But the mouse does not funtion normal as expected. It does not work with swiping and scrolling.
3. I could not re-install boot camp 3.0 from windows.old nor from the Mac OS X installation disk. When I tried to run setup.exe from the MAC OS X snow leopard, I got the error "Boot camp x64 is unsupported for this model"
I am really disappointed that boot camp 3.1 is not universally supported for all mac book or mac book pro.
I need help to re-install boot camp for my Windows 7? I bought the upgrade through education upgrade program and I selected to get 64 bit version so I do not want to rollback the installation to 32 bit.
Please help.

Using Boot Camp to install Windows XP: problems with display going blank

I have a new Mac mini (early 2009) connected to an older NEC MultiSync LCD (VGA only) display through a KVM.
I initially used the Apple Mini DisplayPort to VGA adapter to make the display connection.
All worked fine with Mac OS X, but when I attempted to use Boot Camp to install Windows XP (Home), the display would go blank with the display saying "no signal" at some point during the install and I couldn't get the mini's display back without power cycling the mini. Numerous attempts at removing the Boot Camp partition, re-partitioning, and retrying resulted in nothing but frustration. I typically had to force the mini to boot from the OS X install DVD or Mac partition to make the mini usable again.
I have used my LCD display and KVM combination with a variety of computers running a variety of operating systems, including older Mac minis running both Mac OS X and XP, with no problems. And I intend to keep using it, so I wasn't going to assume the problem was there!
After noting that Apple had already released a [firmware update|http://support.apple.com/downloads/Mini_DisplayPort_to_VGA_FirmwareUpdate] for this adapter to address "[possible intermittent flickering and compatibility issues|http://support.apple.com/kb/HT3492]", I double checked that it was up to date--and it was. But, it made me suspicious that this adapter might have some more problems and be the source of the troubles I was experiencing.
So, I got an Apple Mini-DVI to VGA adapter and tried that.
No more display problems! Everything works fine with Mac OS X. Windows XP installed without so much as a flicker, and it works smoothly with my setup.
I'm curious if I'm the only one who was affected by this problem?

Restart your Mac while holding down the Alt/Option-key until you get to the Boot Selection Screen.
Choose to boot OSX.
Use the BootCamp Assistant to remove the Windows partition.
Go to System Preferences then Startup Volume and rest the default to be your OSX volume.
Reboot your Mac again.
Follow the instructions from here http://support.apple.com/kb/TS3173 and use the BootCamp Assistant again to install Windows 7

HT3777 How to install Boot Camp on 32bit Windows 8 on a 2011 MacBook Pro?

I used Boot Camp to install Windows 8 Consumer Preview as the 2nd OS on my 2011 MacBook Pro. However after the installation I cannot install the additional Boot Camp just the drivers for webcam/wifi/ethernet/cardreader/display/chipset etc.
But I would like to be able to use the function keys to adjust the brightness and volume like on a normal laptop without having to go through settings.
Anyone know how?

You need to install the Boot Camp Windows Support Software, but I have no idea which version of OSX you have so, if 10.6.x the software is on the OSX install disk, likewise for 10.5.x, if you are running 10.7.x (lion) it is a download from the Boot Camp Assistant.

Welcome to Apple Support Communities
Boot Camp Support Software 5.0.5033 supports Windows 8.1 and can be used with that version. The Mid 2011 iMac is compatible with Windows 8, so you should not have any problem by installing Windows 8.
Follow Apple's steps > http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf

I'm using a 2014 iMac and a Win 8.1 64bit install disc with bootcamp. I created the ISO according to the instructions but when I selected it in bootcamp I got the following error "Boot Camp only supports Windows 7 or later..."

Bootcamp rejects the ISO file made from a windows 8.1 disc with the error message "Boot Camp only supports Windows 7 or later installation on this platform. Please use an ISO file for Windows 7 or later installation."
How do I get past this?

Hi Loner T
No the ISO is just 64bit. I bought a shrink wrapped copy of 8.1 full version. It has two discs, one for 32bit and one for 64bit. I used the 64bit disc.
I inserted it in an older iMac that has a dvd drive, and shared that across to my new iMac. I used disc utility to create a disc image following instructions I found here...
Boot Camp: Creating an ISO image from a Windows installation DVD - Apple Support
This created an ISO file. I then went into bootcamp but when I tried to use the ISO file to create a boot USB it failed with the error above.

I Mini with an i7 processor. I would like to use Boot Camp to install windows based CAD software on my MAC. Would it be better to use a plugin external hard drive to load my software on and if so what hard drive would you recommend?

Thank you for your quick response. I can then use a ZIP drive for data storage. I want to keep as much of my hard drive free of data as possible.

Boot camp installation of windows 8.1

Hey Gang,
Struggling here with using boot camp to load windows 8.1.
My machine: Macbook Pro retina, 15 mid-2014 2.8GHz, OS X 10.9.5 867GB
Strange I cannot find straight forward directions on the web.
Everything apparently works smoothly until windows starts up. I cannot find the Boot Camp partition.
Got to this point 5 times now.... :-)
HELP!

What is your exact machine and what's the error

Is it possible to use Boot Camp to install Windows on an external HD?

So I don't use up space on my internal hard drive, would it be possible to use Boot Camp to install Windows to an external hard drive?

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.

I've downloaded the Window support option software and the WindowSetupBox.exe and copied it to the USB drive.

Boot Camp drivers for windows (download)

I am trying to instal windows 7 on my MacBook Pro thru Boot Camp. Does anyone know where I can download the Boot Camp drivers for windows. I can't find them on the apple website and I don't have my Mac OS X instal DVD with me.
Thank you

Only if you don't mind a Windows system lacking most features and thus beaing nearly unuseable.
Applying the appropriate drivers for hardware support is a must for all operating systems.

Unable to install Boot Camp Drivers for Windows

Mac Pro (2) 3.2 Xeon quads
Mac OS 10.5.2
Boot Camp side - Windows XP pro x64 w/SP2
Step 3 listed in the instructions for setting up Boot Camp is to Install the Boot Camp drivers for Windows. At this point Windows recognizes my Mac Install disk 1. I get the following message: "the installer encountered errors before Boot Camp could be configured. To retry these operations at a later time, please run the installer again." I am not sure if I needed to do something to install the Service Pack 2? My firmware is at MP31.006C.B02 and 1.25f4. When I checked for the latest firmware, it returned a message that it was not necessary.
Maybe the XP pro x64 is not compatible?

I did install windows xp sp2 32 bit on my macbook pro 2.2 GB and I'm getting the same ...
When trying to install boot camp drivers, a message came up saying:
Boot Camp requires that your computer is running Windows XP Service Pack 2 or Windows Vista.
The only option it gave me was to click the "OK" button. When I clicked OK , another message came up saying:
Boot Camp Installer completed. The install encountered errors before Boot Camp could be configured. To retry these operations at a later time, please run the installer again. Click "finish" to exit installer. I am running a brand new full retail version of windows xp service pack 2. Applecare will not help blaming Microsoft and of course Microsoft is blaming Apple. What a bunch of useless crap!! Can anyone help??
