Boot camp error installing Windows 8.1 "An unexpected I/O error has occurred"

Well, just like it says on the title, when im going to install windows 8.1 in my MBP (late 2011 13" i7) it gives me a blue screen and the message
"RECOVERY
There was a problem with a device connected to your PC
An unexpected I/O error has occurred
Error Code: 0x00000e9
This problem can happen when a removable storage device is removed while it`s in use or is failing. Properly connecting any
removable storage and restarting your PC may fix this problem."
I dont have any peripherals connected to the MBP while restarting or booting windows installer....
Anyone had this problem while installing Windows?
Any tip of what to do??

If you tried to install Windows 8.1 and it failed at 73% then Windows 7 is lost if you did not create recovery disks.
Should you wish to install Windows 8.1 and you the Win 8.1 license key you could download and create a Windows 8.1 ISO and burn it to USB or DVD to reinstall on your computer.

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

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.

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.

While i was running boot camp to install windows 7 i had to cancel operation. Now my mac comes up black screen with a curser at top

while i was running boot camp to install windows 7 i had to cancel operation. Now my mac comes up black screen with a curser at top

First of all, start your Mac with the Alt key pressed until the boot manager apears. If your keyboard is wireless probably you should press the power button at the same time you start the Mac.
After, go to Bootcamp Assistant and remove the windows partition and do all the process again.
Remember to remove all the USB/Firewire/Thunderbolt devices that are attached to the Mac during the windows installation.
Once windows boots for first time, install windows support software with all the drivers.
IMPORTANT: If the windows partition doesn't boot correctly (Black screen with white blinking cursos at the left top corner) do this steps to boot windows:
1- Start the Windows Installation DVD at system start.
2- Click on Repair System, not install.
3- Select Command Prompt
4- Run these 3 commands: (Press enter for each command)
     Bootrec.exe /FixMbr
     Bootrec.exe /FixBoot
      Bootrec.exe /RebuildBcd
5- Exit command line (type exit)
6- Click on Restart button.
7- Boot the Mac and you will see that It automaticaly loads windows
Tell us how it goes!!
PS: Sorry for my bad english!!!

Using Boot Camp to Install Windows 7. Keep getting error message "Installer Disk Not Found"

I'm partially throught the Boot Camp set-up process and keep getting the same error message when trying to install Windows. The disk is in the drive, not sure why it's not recognizing it.

I had this problem on my brand-new Mac Pro, but fixed it in my case by burning another copy of the installer disc (from the official download image, not a pirate copy lol) at a SLOWER speed, rather than allowing it to burn at the "maximum possible" setting. This gives the laser more time to properly record, but it didn't perceptually increase the time it took to burn the disc.
I speculate that error-checking is too stringent, but weak; that is, not intelligent enough to correct any read errors. Of course, Apple's test configurations are likely using commercially-produced off-the-shelf discs rather than burned from downloads or they know to never use max speed out of habit.

Do I need boot Camp to install Windows on a separate drive

I'm getting a new Mac Pro and want to install Windows XP on a new separate drive (I have the need sometimes to be running in full Windows mode). Do I need to use BC? If someone has the procedure I would appreciate it!
Also can I then use that windows install to then install VM Fusion to use unity to run some Win Apps while in OSX... Thanks in advance

I'm a newbe to Mac Pro and I'm still confused about loading Windows XP. I have Fusion and would prefer to run it and Windows on a separate drive. (I don't expect to need Windows for much, but I don't want to have to reboot to use it.) I think I'm hearing that Fusion must be loaded on to a disk or partition formated with Mac OS Extended. Then Windows would be loaded on to disk or partition formated in FAT or NTFS. Is this correct? Can Boot Camp be used only to format the Windows partition or do I need it at all? ( I guess if Fusion can setup a Windows formatted partition, I would not need Boot Camp.) If I start with a clean drive, Mac formated, does the following sequence make sense?
1. Use Boot Camp to setup a Windows partition on part of the new drive.
2. Load Fusion into the remaining Mac formatted partition.
3 Load Windows into the Windows partition.
4. Done - Ready to load PC software into the Windows partition.
Sorry to be so elementary and if there is another sequence that makes more sense, please let me know. Thanks in advance!

Can I Use Boot Camp to Install Windows XP on Late2012 MacMini

I can't remember everything I've read here in the Community, I still have my Windows XP laptop, haven't used it except to transport videos. Can I use Boot Camp to partition & install the XP on my Dec 2012 Mac Mini? Running Mountain Lion 10.8.5. I still have my Seagate ext HD 1.5 TB, connected to the Mini, but haven't reset it to Mac only. I'm having a slight prob with memory loss, mine, not the Mac's. I think I read that I can't do this with Mountain Lion, but when I try to find what I think I read, it's so far back, I can't get to it. Please help? Thanks in advance.

The Late 2012 Mac mini only supports 64-bit Windows 7 and 8 versions, so you can't install Windows XP with Boot Camp.
If you need Windows XP, download an application like Parallels, VMware Fusion or VirtualBox, create a virtual machine and install Windows XP there. You shouldn't have any RAM problem with Windows XP.
OS X can copy to FAT and exFAT drives, so you can format your external drive in "MS-DOS (FAT)". First, open Finder, choose your external drive in the sidebar and copy all the files to the desktop. Then, use Disk Utility to format your external disk in "MS-DOS (FAT)" > http://pondini.org/OSX/DU1.html Finally, copy all the files back

I'm trying to use Boot Camp to install Windows 7 Enterprise on a 2011 MacBook Pro, but most of the drivers aren't installing correctly.

Apparently, the only boot camp functions that work are restarting in Mac OSX and double-touch right-clicking, which I got after downloading the BootCamp 3.2 upgrade.
This means no sound, no Direct3d (though I've installed the Intel drivers manually and that's now working), no keyboard functions, and no internet access by ethernet port or wifi, which means I won't be able to activate Windows and this install will soon die a quiet death.

Boot Camp not installing Windows 7 - "No bootable device, insert boot disk and press any key."

I need some help with something. A while back, I put a brand new hard drive in my MacBook, a 500 GB model to replace the 120 GB one. I cloned everything successfully to the new drive via Carbon Copy Cloner, but now I want to make a Boot Camp partition on the drive. The SuperDrive in it is defective, so I use an external FireWire drive. So far the Boot Camp Assistant in 10.7 Lion works fine in creating the partition, but when it gets to the part where it tries to boot into the Windows installation disk (32-bit Windows 7 Home Premium, or could the 64-bit work fine as well?), it shows a black scree nwith "No bootable device, insert boot disk and press any key." I try pressing keys, but nothing happens.
I also tried using rEFIt, but that didn't work out either.
Here are the specifications of my machine...
MacBook (Early 2009 model)
2.0 GHz Intel Core 2 Duo processor
4 GB of RAM
500 GB SATA hard drive
Dual-layer SuperDrive (defective, may replace it once I have the cash)
NVIDIA GeForce 9400M graphics chip
Mac OS X 10.7.2 Lion
Can anyone help me out with this? Is there some sort of workaround?

Believe it or not, it was the FireWire drive that was the problem! I managed to successfully install Windows 7 using an external USB DVD drive!
Well I am truly staggered, I have tried this on two different MacBook Pros, with three different external USB optical drives. Don't know if you googled as I suggested but you would find hundreds of others who have found same thing. The exception is MacBook Air which works with the Apple writer, but I don't know much about this.
Were you doing any of the special workarounds with refedit etc?
What model USB DVD 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

Boot Camp failure installing windows??

Hi all, I have been trying to install windows for few days now with no success.
I have a Macbook Pro (Uni) 17" with OS X 10.6.8 and boot camp 3.0.4. Started few days ago by partitioning the hard disc, assigning 35 gigs for the windows (to be) partition without a problem.
Next step was either selecting to download or instert DVD for the installation. First option with the downloading continuously failed and couldn't find any software to download. The other option (inserting the DVD) was also a failure. Tried to connect a USB stick with the windows installation disc on it but the computer still didn't recognize it.
Also tried restarting while holding the ALT key but I get no options for a start drive other than the Macintosh HD.
Can anyone please help out because it is sort of becoming a pain with all the hassle.
Do I need to install a different Boot Camp Assistant? Do I need to update anything?
Thanks in advance

Hello zeeman,
Thank you for the details of the issue you are experiencing when trying ot install Windows on your MacBook Pro. I recommend reviewing the steps in the section titled "If Windows didn’t install properly" on page 11 of the Boot Camp Installation and Setup Guide:
Boot Camp - Installation & Setup Guide

Thank you for using Apple Support Communities.
Best,
