Installing windows 7 or later

i wonder which is better in terms of performance to install windows through Boot camp or through a vitual machine such like parallels ? thanks in advance for any guidance in this concern

Install under BootCamp and you need to alter the boot sector of the drive. Also you cannot create any more partitions.
But Parallels can use the BootCamp Windows as is "image", giving you the choice of "how to use it when".

"Install Windows 7 or later version" check box not showing up in Boot Camp

I am following a Reddit guide to dual boot Windows 7 on my late-2011 MBP. I've done every step up to installing Windows 7, but there is no check box to "Install Windows 7 or later" in Boot Camp. I've tried several other resources but none mention this. There is a "Remove Windows 7 or later version" check box which has a description stating it can install a Windows partition as well, but when I select it and click to go ahead it only has a selection to remove a Windows partition. I hope I'm just having a brain **** here, because I've been at this for a minute and it's causing hair loss at 21. Haha.
Ohh, and here's the guide I'm following: http://sampower.ie/windows-7-on-mavericks-via-bootcamp-and-usb/

your mac seems to think you had installed windows before
do you have more than 1 partition on your drive, if so, boot camp assistant will not work
if not, restart your mac and do a pram reset
open disk utility and repair permissions twice
open bca and try again

Installing Windows 7 on Late 2013 iMac w/ Fusion Drive

Sorry in advance for the long post, but I have tried to exhaust all possibilities, and bring as much knowledge about our environment to the table to avoid confusion.
Here's our goal: Install Mac & Windows on a Late 2013 iMac with a 1TB Fusion Drive
Install our Mac Image with Deepfreeze on Partition 1
Install our Windows 7 x64 Image with DeepFreeze on Partition 2
Here's why our goal cannot work out of the box:
Deepfreeze for Mac, is not supported on a Fusion Drive. Now before anyone says "just don't use deepfreeze"...we are using it, and that is that.
In order to get our existing image to work on the iMac, we had to split the Fusion Drive.
Splitting Up the Fusion Drive
We booted into Recovery, Opened up terminal, retrieved the LvGUID, deleted it, and split up the SSD from the HD.
So now, we have a 128GB SSD, and 1TB HD showing up under Diskutilitiy.
We then partitioned the 1TB HD, into two, 500GB Partitions. One for Mac OSX 10.9.4, and the other for Windows.
The 128GB SSD is going to be used for scratch space, temp, etc. And is irrelevant at this time.
Deploying our Mac Image
After splitting the Fusion Drive, we netbooted and installed a "NetRestore" of our image. Worked completely fine, no issues. DeepFreeze Works fine, the 128GB SSD shows up just fine, and the other 500GB Windows Partition shows up fine. All drives / partitions can be written to with no problem.
Deploying our Windows Image
Deployed our Windows Partition image as we have done in the past, by booting into a windows PE Disk. (We have other various 2009, 2010, and 2011 iMacs across campus, with NO FUSION DRIVES installed, and dual boot them successfully using the same procedure. Minus the splitting of the fusion drive part of course) After the Windows image is deployed to the windows partition, we then boot it up to a Windows 7 Install disk to fix the MBR, Bootrec, and BCD options to allow it to boot properly. Here's where we run into issues: Upon getting the Windows 7 Install screen, the USB Keyboard and Mouse, DO NOT WORK.
Here's the options we've tried to get them to work properly
1. Tried another known working Mac USB Keyboard & Mouse = Failed
2. Tried a known working Windows Keyboard & Mouse = Failed
3. Plugged Just a known working Mac Keyboard into each USB Port to see if recognized = Failed
4. Plugged Just a known working Windows Keyboard into each USB Port to see if recognized = Failed
5. Plugged Just a known working Mac Mouse into each USB Port to see if recognized = Failed
6. Plugged Just a known working Windows Mouse into each USB Port to see if recognized = Failed
7. A Windows 8.1 Recovery USB will boot and the USB Mouse & Keyboard are recognized and installed! (YAY!!) However, we cannot repair a Windows 7 install with Windows 8.1..
BootCamp Drivers & Support Media
Downloaded the Current BootCamp Support drivers to enable the USB and other various drivers to be loaded during setup (Placed the $WinPEDriver$ and AutoUnattend.xml, and BootCamp folder on the Root of a USB, and modified a Windows7 Installation disk and placed on the root as well) The drivers do not load. Have also placed on a brand new USB2, and USB3 flash drive formatted at FAT32, to see if that made a difference, which it did not. The BootCamp USB made within Mac, it loads saying "Now booting into Boot Camp Assistant Created USB Drive..." or something like that (Don't remember the exact Message)
Side Note:
Restored Fusion Drive to its original State, and booted from the BootCamp USB drive, still no usb Mouse & Keyboard Support.

How to install Windows 7 on Late 2013 Macbook Pro?

I purchased a brand new Macbook Pro last week, retina display and all. I've enjoyed it thus far, yet for whatever reason, I can't seem to install windows on a partition in BootCamp like I used to be able to. I'm on Mavericks of course, 10.9.3. I tried installing Windows on an 8gb flash drive, only to find it freeze right as the Windows initial setup comes up. I have no disc drive on this laptop, and I see no reason why I would have to buy an external optical drive just to install windows. I have an ISO file from my university, and all I want to do is use it. Also, VmWare Fusion is not what I'm looking to use.The Graphics card driver fails for most of my favorite steam games. I'd like to use bootcamp how it used to be. I tried editing the assistant's .plist after finding a tutorial on google, but Bootcamp crashes every time. I'm out of options. So my question is how do I install windows 7 on this computer?
Really hoping someone can solve my problem. All I want to do is play Sniper Elite III, and nothing will work. Thank you

Hello Wes109,
Thanks for using Apple Support Communities.
The link below is the help documentation for Boot Camp, which will show you the exact steps to go through in order to install Windows on a Boot Camp partition:

Installing Windows 8 on late 2012 iMac 3TB SATA Disk

Yes I know installing windows on the new 3TB iMac through bootcamp is not officially supported, but after doing some research it seemed that it was quite possible to do so anyways. Twocanoes seemed to have the best solution for going about this so I gave it a try
http://blog.twocanoes.com/post/42453643591/bootcamp-on-a-3-tb-fusion-drive
I seem to have run into a problem at the very last step. I successfully created the partitions as above, created a bootable usb with bootcamp on a different mac, and then when I go to select what drive to boot from, my bootable usb shows two different drive options (Windows and EFI). If I select Windows, I can successfully install it on to my partition, but no compatibility drivers seem to be installed with it (internet, graphics, bluetooth). If I boot from the EFI option, I make it to the windows installer, but then receive an error telling me:
"The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks. Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk controller is enabled in the computer's BIOS menu."
Any help on what I am doing wrong or what I might try will be greatly appreciated.
Cheers

Welcome to the Apple Support Communities
In the past, Windows could be installed in PCs with UEFI 2.0, but Windows 8 adds compatibility for EFI 1.x computers. What does it mean? You can install Windows in EFI mode on any Intel-based Mac with a 64-bit processor (Intel Core 2 Duo or newer).
This mode provides a better hardware compatibility for the installer, but it will give you headaches to make it work. For example, a Mac uses a hybrid GPT/MBR table for the hard drive. It uses GPT to start in OS X, and MBR to start in OS X. The problem you have is that a Mac emulates the MBR automatically when you make a partition for Windows in the hard drive, and this is the reason why you can't install Windows in EFI mode on your Mac.
In order to install Windows in EFI mode, you will have to leave some free space in the hard drive, and then, create the Windows partition in the Windows installer, after starting in EFI mode. However, I don't recommend you to do this, because after installation, the compatibility will be worse. You may have Internet working and the graphic card, for example, but Apple won't release updates for it, because it's not considered Boot Camp.
In conclusion, install Windows using the "Windows" option during startup, and wait until Apple releases Boot Camp drivers compatible with Windows 8. EFI mode for Windows provides some great advantages, but Apple doesn't support it at the moment

Install windows on iMac Late 2009 without Optical drive

Hi, i have an iMac 27 i5 11.1 where i want to install windows 7 (or 8). I already did it 2 years ago without problems, but in the mean time i formatted the drive and my optical drive stopped working so i replaced it with an ssd.
I'm trying to install windows but i don't know how without a superdrive. I tried with an external usb dvd drive and it didn't work (you can't install windows from a non apple dvd drive, it is a known problem) but it don't work, so i tried to create an usb installation key of windows with microsoft official tool and also with boot camp tool, both doesn't work (when i select them on the boot i get an apple alternated with a prohibition mark and a folder with a question mark, exactly as with the dvd drive). So i thought that maybe if i can install windows on an external drive and boot it from there i will be able to launch the install directly from windows skipping the problem, but you can't install windows on an external drive..
I'm running out of ideas, someone can help me installing windows on my imac? thanks in advance

There is your answer, now stop stressing and move on without it.
Sure, good answers.
Apple doesn't want to = You can't
Apple doesn't let you = You shouldn't
Too bad i made it. So it is possible, even if you and apple said it's not.
I installed virtualbox, created a virtual machine with the full disk access, started installing windows, when the copy of the files ended and the vm was rebooting i simply closed it and rebooted my imac and finished the installation directly on the imac, everything went well...
Luckily i didn't take apple's word as a written law and i use my own brain..
If you had posted in a Virtual Machine forum, or asked if you could install Windows using other than Bootcamp Assistant then someone would have advised you to use a Virtual Machine like Parallels, Fusion, or VirtualBox. But you posted in the Bootcamp forum so we assumed you wanted to create and use a Bootcamp partition.
So the answers provided you, based on your questions in this Bootcamp forum were spot on and appropriate.

How I Managed to Install Windows 8.1 Pro on an iMac 27-inch, Late 2013

As is typical with many of my Boot Camp installs, this one did *not* goes as smoothly as planned. This installation was particularly troublesome, so I thought I would share how I managed to set up Boot Camp on a brand new iMac (27-inch, Late 2013) using a Windows 8.1 Pro DVD and an external Apple SuperDrive. These are the steps I took:
Download Boot Camp Support Software 5.1.5640 (http://support.apple.com/kb/DL1721)
Copy Boot Camp Support Software to empty MS-DOS (FAT)-formatted USB key
Run Boot Camp Assistant and select third option only (Install Windows 7 or later version)
Computer would reboot after Boot Camp Assistant finished but would boot back into Mac environment and not continue Windows installation
Boot computer holding down option key and select Windows (with DVD icon) and go through initial setup process (could go as far as trying to format Boot Camp partition as NTFS and then got stuck)
Quit Windows installer and reboot computer holding down option key and select EFI Boot
Run Windows installer
These same steps worked for another iMac (same model) that I set up later the same day.

Note: These types of discs or activities are not supported by DVD or CD sharing:
DVD movies.
Audio CDs.
Copy protected discs such as game discs.
Install discs for an operating system such as Microsoft Windows (for use with Boot Camp), or Mac OS X.
Burn a CD or DVD

Installing window 7 to macbook pro late 2011

I am trying to install Windows 7 to a Macbook Pro (late 2011). I got this far: After downloading Bootcamp 5 and going into Bootcamp assistant and clicking both, a) Download the latest windows support software from Apple, & b) install Windows 7 or later version.
NEXT: Installed external 8G usb drive for Windows support software to download to
NEXT: In about 10 seconds it downloads then never moves on the "visual" download scale???????? THIS IS WHERE I GET STUCK
ANY HELP WOULD GREATLY BE APPRECIATED

Welcome to Apple Support Communities
As it looks like you can't download the Windows support software from Boot Camp Assistant, download it at the Apple site > http://support.apple.com/kb/DL1638 Follow the steps to burn it to the USB drive.
Then, open Boot Camp Assistant and install Windows. Don't mark the option to download the Windows support software

Problem installing Windows (7, 8.0, 8.1) on BOOTCAMP - Mavericks

Hallo guys,
First I want to say thanks a lot to Christopher Murphy, because one and a half years ago I was having problems the same like the 1st post on that topic and with the instructions from Christopher I was able to get back my BOOTCAMP with Windows 7. Now I think that the commands from the 1st post changed something that is making my current problem appear. All was working like a charm till few days ago when I was get a decision to update to Mavericks.
Previously I was with Mountain Lion 10.8 and with Windows 7 on Bootcamp. The hardware is iMac Late 2010 27'' with 1Tb SATA HDD.
Few days ago I have deleted the BOOTCAMP partition and resized the disk to only 1 partition (with Bootcamp wizzard). Then I made a boot usb stick with Mavericks and then started the installation of Mavericks from my USB Stick. I have deleted all partitions and created a new one when the installation asked me to choose a partition. So everything was fine and Mavericks is ok and working great. Now the problematic part.
I have created a Bootable USB Stick with Windows 8.1 first. I used some windows program to made it which I was using before and never had a problems on normal Computers (PC, not Apple) to boot and installing that windows from the same USB Flash Stick and the same Windows 8.1 and so on. I started Bootcamp Wizzard on my new Mavericks and than I notice that I have only 2 options there:
1. Download drivers
2. Install windows 7 or later version
I have already the bootcamp software support drivers downloaded before and I have leave only the second tick checked.
I tried to press Continue, but the Wizzard told me that it doesn't recognize a Windows DVD and cannot continue. Asked me to insert a Windows DVD and to continue.
Now it's time to say that my DVD device is not working and I cannot use it.
So I was thinking that the problem is coming from my USB Stick and tried few other programs to make a bootable usb stick with windows. That doesn't help.
I started to read and googling the internet. I tried few options from some guys with a close problems. Reset with Options+CMD+P+R, to format USB Stick fully etc. Then I found that if I install daemon tools and mount a Windows 8.1 ISO the Bootcamp Assistant will continue on the next step and will build the BOOTCAMP partition. I made that and restarted the computer with the USB Stick plugged in. I got a message that there're no system disk and to insert one and to press any key to continue (or something like this). Then I made a hard restart and tried to hold the ALT (Option) key after the startup chime. I got the list of bootable devices, but the usb stick wasn't there Only Mavericks partition and HD Recovery one. Tried few more things with no luck.
Then I found a topic where a few guys explaining how to get the 1st option on Bootcamp Wizzard (Create a Windows 7 or later version install disk). I changed the plist file in Bootcamp Assistant, then signed the app with xcode tools and yahoo, I got that option enabled.
I made again a bootable usb stick with windows 8.1 from ISO with the Bootcamp Assistant 1st option. Then when I restarted the Mac keeping the ALT pressed it was a surprise that the USB stick with windows 8.1 showed up. I started Windows 8.1 setup, entered the serial number and then I selected the BOOTCAMP partition and the Next button wasn't active and error message was written that:
"Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks."
I tried format, delete partition, create new etc with no luck. Then I tried to recreate the bootcamp partition with Disk Utility, but with ExtFAT format and again no luck. I found another topic on internet where some guys are talking that only Windows 7 can be installed in that way on Mavericks BOOTCAMP. I don't know that this is true or not, but I tried with Windows 8.1, Windows 8.0 and now I'm going to get a Windows 7 from a friend these days, but I don't think that it will work.
Is there someone who can help me out somehow or to tell me some tips or opinions what to do next?
Here are few infos:

Looks perfect with the Free Space. You can verify this by running sudo gpt -vv -r show /dev/disk0.
If you try the EFI boot, please pick this Free Space slot, and it will get split into a 128MB MSR and the remainder as NTFS, if the installer finishes successfully. You may be able to install, but a preUEFI model cannot use the MSR to boot the main Windows partition, but a UEFI compliant machine can.
On a Late 2013 15" rMBP (which is UEFI compliant), this is what Bootcamp on GPT looks like. (Notice GPT#4 - MSR and GPT#5 - NTFS).

How to Install Windows 8 on (some) unsupported Macs

Open finder
Open Applications folder
Open Utilities folder
Right click on Boot Camp Assisstant > Get info
Click the Lock in the bottom right corner and enter Admin password
Click the plus in the left corner and add your user.
Give yourself Read & Write privleges
Click the lock again
Right click on Boot Camp Assisstant > Show package contents
Open Contents folder
Open Info.plist
Scroll to the bottom where the <key>Win7OnlyModels</key> string is
delete the whole string (in my case <string>MacBookPro5,5</string>)
You will be promted that your don't have permission and to make a duplicate. Click Duplicate.
Backspace out the space between the lines if there is any.
Save as Info.plist to the Desktop.
Find the Finder window with the Contents page in it.
Change the name of the Info.plist to Info.plist.bak. It will automatically add .plist to it
Drag the Info.plist file from the Desktop the Contents folder.
Authenticate yourself
Let the file be moved.
Click back twice.
Open Boot Camp Assisstant
Click next.
Install Windows 7 or later version is now shown.
There you go. Windows 8 on unsupported Macs in 25 steps, or a couple minutes. (not including partition or install ;P)
If you don't know what your Model number is, Click the Apple in the upper right corner, About This Mac > More Info... > System Report... > and it will show Model Identifier. That is the <string> that your will need to delete. If you don't see it chances are your won't be able to do this. Could try this other "Trick" in here: https://discussions.apple.com/thread/4897066?start=0&tstart=0

"If you don't see it chances are your won't be able to do this."
WRONG! YOU WILL BE ABLE TO DO THIS THANKS TO ME! FIRST FOLLOW ALL OF "aplet's" steps and then do this:
<key>PreUSBBootSupportedModels</key>
          <array>
                    <string>MacBook7,1</string>
                    <string>MacBookAir3,2</string>
                    <string>MacBookPro8,3</string>
                    <string>MacPro5,1</string>
                    <string>Macmini4,1</string>
                    <string>iMac12,2</string>
Click the Apple in the upper right corner, About This Mac > More Info... > System Report... > and it will show Model Identifier.
Change it by deleting "Pre" and adding your Model's <string>
For example I ended up with this:
<key>USBBootSupportedModels</key>
<array>
<string>MacBook6,1</string>
<string>MacBook7,1</string>
<string>MacBookAir3,2</string>
<string>MacBookPro8,3</string>
<string>MacPro5,1</string>
<string>Macmini4,1</string>
<string>iMac12,2</string>
Then finish it off by following "Giuseppe Cantarella's" Steps!
AND THAT'S IT! YOU'RE WELCOME!!!!!
P.S. THANKS TO "aplet" for giving me guidance on the first steps and inspiring my edit, and "Giuseppe Cantarella" for finishing off the whole process!!!!

Boot Camp sees my internal SSD as an external drive - can't install Windows 7

I've just replaced my old 1TB drive on my Mac Pro (mid 2010) with a 1TB Samsung 840 EVO. To get the best speed I've installed it using the Sonnet Tempo PCIe interface. I performed a fresh install of Mavericks 10.9.1 and the system absolutely flies.
However, I wanted to also install Windows 7 but Boot Camp Assistant will not allow me to do this. It warns....
You cannot partition an external disk, a RAID disk or an internal disk on which FileVault encryption is in progress.
When I look through the system information, my SSD is reported as an external drive - which is why I guess BCA refuses to partition it (and ghosts out the option to install Windows 7 or later version.
Here's the system information under storage...
MAC SSD:
Available:          941.47 GB (941,471,612,928 bytes)
Capacity:          999.35 GB (999,345,127,424 bytes)
Mount Point:          /
File System:          Journaled HFS+
Writable:          Yes
Ignore Ownership:          No
BSD Name:          disk0s2
Volume UUID:          DED0438B-7A12-3AB0-8E6D-E6911C595CA2
Physical Drive:
Media Name:          Samsung SSD 840 EVO 1TB Media
Medium Type:          SSD
Protocol:          SATA
Internal:          No
Partition Map Type:          GPT (GUID Partition Table)
S.M.A.R.T. Status:          Verified
So my questions are... Why does OSX identify it as an external drive? Is it because of the PCIe interface? And, more importantly, how can I get around this to allow me to install Windows 7? Could I temporarily remove the PCIe card and install the SSD in a standard drive bay and then run BCA? Any ideas???
Thanks.

Kappy is dead on with 1 more tweak ... remove the PCI card, and put the SSD back onto a normal drive bay and fully install Windows.
Then, put the empty PCI card back into the machine and boot into both OSX and Windows ... both OSs should work just fine.
Now, put the SSD onto the PCI sled and test both OSs.

Can't install Windows "No bootable device -- insert boot disk and press any key"

I'm running OSX 10.9.3 on my Macbook Pro 13-inch, Early 2011 and trying to install Windows 7 via Boot Camp Assistant and I'm using a flash drive loaded with bootable copy of Windows 7 Ultimate (legal, if that makes any difference).
Here's what I've been doing:
1. Plug in my flash drive, then on Boot Camp Assistant, click "Install Windows 7 or later version"
2. Set my Windows partition to 45GB and continue... so far so good...
Then the problem:
3. My computer restarts, goes to a black screen with the message "No bootable device -- insert boot disk and press any key"
The flash drive is still plugged in but is it not being recognized or something? Nothing happens when I press any keys.
I can use OSX just fine by holding down "Alt/Option" on restart, but in my case what can I do to continue further with the Windows install? It's basically an empty partition as of now. Any help appreciated!

Ive been having this problem and have been trying to figure out how to fix it for almost a week now. I have a 2011 17" MBP with the superdrive removed. Ive tried many different methods and many different methods to no avail. If anyone can help, please do!
xxzy, have you tried the KUNU method?
you can find it here:
Bootcamp without Optical disc drive
Scroll down to Kunu's post about his solution and see if it works for you.

Dual booting pre-installed Windows 8 and Linux?

I just bought a G780 with Windows 8 pre-installed. Ideally, I would also like to install some flavor of Linux. I've been searching but not finding much info on how difficult or time-consuming this would be, or if there are any special considerations or anything. I've found some guides on dual-booting Windows 8 and Linux but they were all for installing Windows straight from a disk, not anything where it's already pre-installed, and some indicated they thought it might be problematic to use a pre-installed version of Windows. Anyway I was hoping that if anybody has done this on the G780 or even a similar laptop that you could share how it went and any difficulties you encountered. I'm open to using any Linux distro if it'll be easy to install. I would appreciate any info you could share. Thanks.

I had issues with Windows 8 as pre-installed on my G580, my employer at the time was using Windows 7 only and would not allow upgrades for security purposes. I deleted the entire drive (including hidden) knowing at some point I would re-install Windows 8 or later from retail disk when needed.
Linux can resize partitions during the install process, but be careful not to disturb the hidden partition or the windows boot loader in the process. Linux Mint is the best yet for this purpose, OpenSUSE and Fedora failed, CentOS failed and Ubuntu was not able to boot, but did not "hurt" the windows partitions.
Good luck.

Option disabled on Bootcamp Install windows 7

Hello guys.I have a problem.Boot camp won't let me to select " install windows 7 or later".i have search on Google but I dindt found something..Can you give me a hand please.Thank you!

2 problems
first, you have too many partitions, boot camp assistant will only work if your hd has 1 partition when it starts (usually named macintosh hd), to fix this you have to delete the extra partitions
second, you'll likely need a new w7 iso, dl the correct one from this link
