EFI problem related to Boot Camp

Hi I'm new to the forums,
I'm having problems booting into my windows partition on my MacBook. Everything was fine until I had a recent power failure while using Windows 7 for office work. My Macbook just turned off with no warning. Upon turning on the macbook I get the "No Bootable Device" black screen.
I figured the Windows partition corrupted itself after the power failure. I proceed to delete the windows partition via Boot Camp Assistant in OSX, divide the hard drive again, and go ahead with reinstalling Windows 7. But here's the problem I can't seem to figure out. When formatting the BOOTCAMP partition in the Windows Installer to NTFS, I run into this error:
http://i49.tinypic.com/1043i53.jpg
http://i48.tinypic.com/167mux4.jpg
http://i49.tinypic.com/1zxulo1.jpg
Probably the entire hard disk corrupted after the power failure? Okay, so I freshly reinstall Snow Leopard deleting all the contents on the HD. I even performed a complete format using the Zero Out method in Disk Utility. When the OSX install completed I divided the partition again with Boot Camp Assistant and ran the windows installer only to run into the same error like pictured above. Tried this method again but also ressetted NVRAM/PRAM and SMC. Still no luck.
So I'm thinking some part of the HD isn't working. I remove the HD from the macbook and replace it with the original 80GB hard drive that came with it. This time, instead of installing OSX, I formatted the hard drive in FAT32 with Disk Utility, and proceeded to install Windows 7 without OSX. I STILL get the same error though. Can't ever get passed this error. Arghh. I guess its not an HD problem so I replace my 250gb HD back in.
Did some research on google and decided to run rEFIT for its custom boot screen. For the heck of it I decided to run the Windows Partition that was listed on boot screen. Here is where I run into this error:
http://i49.tinypic.com/2mq6og5.jpg
It says: "The firmware refused to boot from the selected volume."
Could this be an EFI problem? Is something corrupted in the boot rom that is restricting me from booting into the windows partition? I already performed a reset for the NVRAM/PRAM and SMC.
I've tried to reflash the EFI again but OSX won't let me. It says: "This computer does not need this update"
Anybody have any suggestion to what I should do? I'm way out of warranty and have no Apple Care. There are no Apple Store within a 100 miles.

Hi,
I am not sure what to suggest regarding the errors that you are having but I am also running Win7 on my Mac. When I first got my MB, I used BootCamp but I quickly changed to Fusion and then to Parallels (which I like the most) - primarily so I could boot into OSX and still have access to my PC VM's. Maybe you should look into switching your PC environment to VM. Most of the VM software has a feature to 'snapshot' your VM session. This way, if your MB should abruptly power off, you can always revert to one of the snapshots without having to re-install. Anyway, good luck I hope you get the problem resolved.

Problem with starting Boot camp

Hi all,
when i try to use boot camp assistant(open boot camp assistant and click continue) it say 'you must update your system soft ware before using this setup assistant' evebn though I have updated by system using Software update option. Please help out with this problem.
Thanks..

This solved my problem...
I recommend going into your Disk Utility and under your hard drive on the left side click on the macintosh HD and then on the top make sure you have Journaling 'enabled.' (It's highlighted in green on the top menu bar in the disk utility box.)

Serious problem when instaling Boot Camp.

Hi, I hope someone can help me because my boot camp has been giving me every problem imaginable.
When I first tried to install windows, boot camp had no problems creating the partition, but my windows XP, for whatever reasons, did not installed.
So, I borrowed a trial windows from a friend, it installed ok, and I installed 3Ds Max in it(which is pretty much the only reason I needed boot camp, since I don't own a PC), and everything was perfect for the 30 days the trial version lasted.
Then, after it expired, I destroyed, the re-created the partition again, and another friend gave me a copy of his windows XP, and from her everything went to ****. The system installed correctly, but when I ran windows, the graphics were incredibly slow, even dragging a window around the desktop looked really jaggy, and 3DS Max installed, but wouldn't run.
I tried the exact same thing with other 2 windows xp copies(all 32 bit), and the exact same thing happened. And now, I have noticed the when I create the partition for windows, it renames itself "untitled" in the mac os desktop, and, even if I erase it, when I turn on the computer it doesn't get me directly to Mac OS, but rather searches for the windows partition even if it's no longer there. I have to press the alt key for the mac partition to appear.
I hope someone can at least tell me what the **** is wrong with my boot camp, thanks to everybody in advance.

Hi and welcome to Discussions,
as for the startup problem: once you are in OSX goto System Preferences - Startup Volume and set your OSX volume to be the default startup volume.
(During the Windows installation this is set to be the WIndows partition and remains that way until resetted).
For the obvious with the Windows installation: after the successful installation of Windows did you insert your OSX install DVD while in Windows to install the needed BootCamp Windows Drivers ?
If not, then that's why you had these graphics problems.

Urgent help needed related to boot camp and Win7 32 bit

I have installed boot camp and Win7 32 bit on my iMac (2010) but I can't start from my mac os even by holding the option key. Windows doesn't recognize my wireless mouse either, but for now going back to the mac os is the priority. Can anyone help please?

Welcome to Apple Support Communities
Hold the Option (Alt) key after hearing the startup chime and until you see all bootable partitions in the screen. Do you see the OS X partition? If so, select it to start up in OS X. If you want to start up in OS X by default, open System Preferences > Startup Disk, and select your OS X partition.
Respecting to your wireless mouse, you have to install the Windows support software. To download it, you can use Windows or OS X, from this site > http://support.apple.com/kb/DL1630 If you are in Windows, decompress the file and run the installer. If you are in OS X, follow the steps of the website to burn it to a USB drive

MBP with EFI Problem does not boot

Hi everyone,
I have a huge problem with my computer.
After upgrading my iPhone to iOS 7.1 via iTunes i wanted to disconnect my iPhone from my Mac which produced a beachball. I have almost no beachball issues with my Mac since I upgraded to an SSD. After disconnecting the iPhone (beachball still spinning) my computer froze so I had to push the power button until it shut down immediately. After a restart it used it just minutes and it froze again and showed the beachball again. I shut it down with the long press on the power button again and did this several times, what made the problem even worse. After a few restarts I booted into recovery mode and tested the harddrive with disc utility which found a fail, but couldn't fix it (the fail was something with EFI and it sId it couldn't fix it because it can't work with this file format [filevault encrypted HFS+?]). After a restart my Mac didn't boot (and still doesn't) and just shows a blinking folder with question mark in it.
Because I have two USB-sticks with OS X on it (1 with lion and 1 with mavericks) I booted with them and tried to install a backup and even tried to install a new copy of OS X, but I doesn't find the SSD to install it on there. Just a recovery partition.
I have no idea how to fix this without another computer. Maybe I could delete the SSD with another computer, but is there a way to do this with my hardware?
My system:
13" MacBook Pro early 2011, Samsung SSD (840 Evo 500 GB), 8 GB RAM. The hole harddrive is encrypted via filevault 2.
OS: 10.9.2, backup (also encrypted) available.
I would be very thankful for every help and advice you may have.
Greetings,
Jonas

Hello Jonasschoen,
As the issue that affects your Macintosh HD is not one that Disk Utility can repair, you'll need to boot to internet recovery (by holding Command + Option + R at startup). Here, you will need to use Disk Utility to repartition your hard drive by changing the Partition Layout to 1 Partition. Once you've set up a functional volume, you should be able to successfully reinstall Mavericks or restore from your backup.

Problems on installing boot camp on windows vista 64

I've a problem,when I finished installing vista 64,I should install the bootcamp 2.0,I searched many discussions about this.But I can't find the file 'bootcamp64' on my leopard disk(apple\driver\bootcamp64?),I just find the bootcamp.msi,what can I do?
Thank you.

When you insert your DVD while in Vista, it doesn't open to
/Bootcamp directory and doesn't show an Apple setup.exe ?
I think you are fine... I copied it off and keep it on USB and on a data partition NTFS that I have all my data, downloads and files and haven't used the DVD in a year.

Problem to update Boot Camp 2.0 to 2.1 on WinXP

When I user "Apple Software Update" on XP,I get error "Erro ao aplicar Transformações. Verifique se os caminhos de transformações especificados são válidos." In english is something like "Error applying transformations. Make sure the paths of specified changes are valid.".
When I do download update file, same error happens...
Any one have this problem?

The disk itself reads:
"Includes Service Pack 2.....Version 2002"
So it's a full install package that I'm using (comes in a blue box) and not an OEM version (even though I've tried that as well).
Be sure that "now includes Service Pack 2" does not mean it's simply a separate file on the disk. Look on the disk to be sure there is no file labeled SP2. Early versions shipped with SP2, but not as part of XP.
My DVD says, "Windows XP Professional With SP2"

Problems with Boot Camp 2.1 update & Heat Generation with new MBP

After spending a lot of time debating whether to go with a high-end mac or high end PC, I eventually went with a top spec MBP (17” 2.93 ghz). This was a difficult decision to make, not to mention expensive.
I figured - the Mac was the winner although lower spec then a similar priced PC it had a major advantage – to run Windows XP (which I use for some creative and recreational purposes).
I am now very frustrated and angry – the peace of mind, stability and straightforward Mac ideals that I admire have been non existent so far. It has been extremely stressful!
Problem 1 – when setting up boot camp I wanted to go with the NTFS option, so I partioned 50 gig of space. But after choosing this, the only confirmation option that was displayed was for FAT so I was left wondering if that was correct? (I was very slow and methodically following instructions).
*Problem 2* – After boot camp was set up, there was not Ethernet driver in the Boot Camp / OS Install Disk so I couldn’t connect to the net. It is just lucky one of my neighbours has an unsecured wireless network that I ‘hopped’ onto, to download the driver.
*Problem 3* – HEAT!!! when running an old spec video game (Unreal Anthology) the MBP became incredibly HOT. So much so that I had to stop after a few minutes because it was clear that damage was being caused. I have since read on other discussions that this is a problem many other MBP users running boot camp are experiencing.
*Problem 4* – I downloaded the Boot Camp 2.1 update hoping this would help, but all it did was cut all the sound and disable the keyboard apple keys. I had to uninstall boot camp then reinstall the older version to get the sound back (no ethernet connection again!)
I am extremely upset – I feel I have been miss sold. I brought the Mac with Apples reassurances (and their sales patter of ‘oh yeah, your windows programs will work better on a mac’) only to find this is NOT THE CASE.
I hope I have been doing something wrong, because then I can sleep better knowing I have just spent a lot of money on the right tool I need for my job. At the moment I have a nasty feeling of painful regret and stress – everything I hoped to avoided when buying a mac.
If any apple support people or other users can help I would really appreciate any feedback you may have. Thanks in advance…

Hi I too just bought a MacBook Pro 2 weeks ago. I settled on a Mac as I had so much problems running Mac OS on my Dell laptop.
I had OS 10.5 running on my work Dell Latitude D520, it was not a hack but a genuine retail version of Leopard. But I had issues with the keyboard / track pad not working, so I had to use external keyboard / mouse. Not fun on a laptop.
I’m now running OS 10.5.6 and XP 64 bit on my MacBook Pro. I chose XP 64 bit so I can take advantage of the 64bit CPU and the 4 Gig of RAM in my MacBook Pro.
It took me 2 days to get all the drivers to work properly well I say all, the bluetooth does not work but I don’t use bluetooth so don’t really care.
I chose XP 64 bit over Vista 64 bit as Visa is the worst OS Microsoft have come up with to date.
*If any Apple guys is looking at this please let me know if Apple will ever produce XP 64 drivers, I think I’m not the only one interested in the drivers.*
Nick9000 with regard to your problems.
Problem 1
The Mac will only format FAT32 as it cannot write NTFS only read it. You need to choose NTFS when you are installing from the Windows CD, you can still convert your FAT32 system to NTFS within Windows.
Problem 2
I had the same problem but then I was using a non-supported OS.
Problem 3
My laptop runs a bit hot at times but to me all laptops run hot maybe more so Mac laptops. You are running the 2.93 GHz so I guess it does run hotter than my 2.66 GHz.

Boot Camp Problems: Disc Error?

Hi All,
I hope this is in the right forum, if not - I'm sorry!
Have just tried to install XP Pro using Boot Camp, on a 20Gb Partition. Boot Camp created the partition smoothly, and XP installed all of the set-up files onto the new partition.
When it come to restarting the machine however, I had the option of booting from disc again - after that option times out, I get a message "Disc read Error" or something along those lines.
I do have the option of restarting by hitting any key, however the system just freezes!
Does anyone have any solutions to this problem?
Also, should Flight Simulator 2004 run smoothly on Boot Camp running XP?
Your help is much appreciated!
Simon.

I just spent the weekend dealing with this.
Credit to this Austrian guy diagonalinho who posted this in a different thread. I had a little trouble understanding his instructions (looks like English is not his first language) so I am posting the summary that I wrote for another person having the same problem. Credit goes to diagonalinho though.
First, I think someone already mentioned that the reason you are having the problem is because Boot Camp Assistant formatted the XP partition as FAT32. It needs to be NTFS. Windows Setup is supposed to ask you how to format the new partition (see page 13 of the Boot Camp manual). If your experience is like mine, Windows Setup never asks that question. It simply goes from you selecting the C: drive (Boot Camp manual page 11) to the installation process (a blue screen yellow bar marking progress as things are copied to the partition).
Here is a link to the manual that I'm referring to if you don't have it already: http://manuals.info.apple.com/en/BootCampInstall-Setup.pdf
I do not know why the format step is being skipped in some installs but not in all. Call it an "undocumented feature" (e.g., bug).
Here is how to fix it:
Boot Camp Assistant should have instructed you to insert the XP CD in the drive and then it will restart. This is what you want. After some time, you will get a blue screen with white text in the upper left hand corner that says "Windows Setup." On the bottom of the screen there will be some words telling you this and that is loading. Keep an eye on this. It will slowly list a bunch of things that it is loading. Toward the end, it will say something like "Starting Windows Setup." At this point, press and hold the F10 button. Keep holding it until you get a black screen with white text.
You are now in the Recovery Manager. You will be asked what volume you want. The only choice you should have is 1. This is your new Windows partition, it is not your Mac OS partition. YYou may safely type "1" (without quotes) and press return. Then, the prompt will look like this:
C:\WINDOWS\
At the prompt, you type "cd.." (without quotes) and press return, the prompt will now look like this:
C:\
Now, we are going to reformat your windows partition as NTFS. To do so, at the prompt type the following without quotation marks "format c: /fs:ntfs" When typed into the prompt, it will look like this (pay close attention to spacing)
C:\format c: /fs:ntfs
It will give you a warning and ask if you are sure. Type "y" and press return. It will take some time to format and you will see a percentage counter counting up from 1% to 100%. When it is done, you will be back at the C:\ prompt where you will just type "exit" and press return.
Now, Windows Setup should proceed normally.

Can't get Vista 64-bit to format Boot Camp partition

Okay. I went through all the normal steps, I checked back here, read as many threads as I could, and still nothing has worked. The core problem is that after I use boot camp to partition my drive, I boot into the Vista DVD, it sees the partition, I use the Format button to format it to NTSF, it does, then it says "Windows cannot find a suitable volume for installation".
Here's my setup:
Mac Pro 2.8 GHz 8 core, 10 GB RAM, 8800GT card.
3 internal HDs, 2 500 GB drives for my system, apps and media stuff, and 1 250 GB drive just for Windows.
Vista Ultimate 64-bit (yes, a real store-bought copy) Note that this is an OEM copy that's 64-bit ONLY, as opposed to the retail version that has 32-bit and 64-bit on the same DVD.
Here's what I've tried:
- Zeroed out all data on the Win drive, formatted as OS X extended, used Boot Camp to partition for Windows
- Formatted drive as OS X extended, then used Boot Camp to partition it into a 5 GB OS X volume and a ~230 GB Win volume
- Used Boot Camp to partition it as a single Windows volume
- Used Boot Camp to partition it as a single Windows volume, then tried to install Vista onto it without formatting it to NTSF
- In the Vista installer, tried deleting the main partition, creating a new one, then formatting it
- In the Vista installer, tried deleting both partitions (including the 200 GB EFI one that Boot Camp creates) and recreating them
In every one of these cases, after Vista formatted the partition it would not allow me to install Vista onto it, saying it couldn't find a suitable volume for installation.
I noticed that when Boot Camp does it's thing to your drive, it's supposed to create a partition named BOOTCAMP. In my case, it failed to do that when I told Boot Camp to create a single Windows partition on the drive. Instead, the drive would simply disappear from my desktop. It would then show up in the Vista installer, but it had no name. It just said Drive 1 Partition.
However, when I used Boot Camp to partition the drive into a 5 GB OS X volume and a ~230 GB Windows volume, it did create the BOOTCAMP volume and mounted it on the desktop, in addition to the 5 GB Untitled OS X volume. And in the Vista installer it did show up named BOOTCAMP, however formatting it had the same results as all my other attempts.
So after doing this for over 5 hours today, I don't know what the problem is. Nothing I've done, either in Boot Camp or in the Vista installer, is letting me install Vista onto the volume. Vista is simply refusing to install onto my drive no matter how it's been erased, partitioned or formatted. I don't know if this is a problem with the Boot Camp drivers, or with Vista. Maybe it's something to do with this Mac, it's pretty new just got it last week, there's a lot of variables here. The Mac is 100% perfect in all other ways though.
Any suggestions?

It worked! The only way I could get it to work was to pull out both my 500 GB drives so that the boot camp drive was the only one left. And even though the drive wasn't named BOOTCAMP Vista finally installed onto it. So it looks like the bug is just in Vista's installer - specifically that it appears to ignore the fact that you've selected the correct partition to install onto, and it gets confused if you have multiple HDDs installed.
Once Vista installed everything else went fine. I put my drives back in, updated Vista, installed the Boot Camp drivers and it's peachy now. Thanks again for the help.

Yosemite Boot Camp Drivers

Hi,
Thanks in advance for any help I receive. After upgrading to Yosemite, like many, windows 8 was having a problem loading. As soon as the 8 desktop would appear, the screen would go blue and Windows would shut down. I erased the partition and started over. Here is the procedure I used:
1) Launch Boot Camp assistant
2) Download latest drivers to flash drive
3) Boot Camp assistant partitions the drive ( 400 GB Windows partition)
4) Boot Camp restarts and installs Windows (8.0)
5) Windows asks me to select a drive to install windows.
6) I select the BootCamp drive, but I have to use the format tool on the installation page to format it to NFTS (otherwise I cannot install windows.
7) Windows ask for key-key accepted
8) Installation runs fine-Windows asks for all the setup information
9) Desktop appears
10) Boot Camp support drivers program runs automatically and installs drivers-computer restarts fine.
11) Problem-once the desktop appears, as soon as I start to do anything, the blue screen appears that says windows had a problem-
12) no amount of windows self repair works short of taking it back to a point before installing Boot Camp support drivers
Either I am doing something wrong or the problem is the Boot Camp drivers need to be upgraded by Apple.
The error I see on the screen says something about "security check on Ktext" or something close to that.
Any ideas?
All the best,
Ciro

Hi Loner T,
Thanks for the reply. Firs the links Kappy provided are the procedure I followed. To answer your questions, BCA downloaded the the drivers. I assumed that it downloaded the 5.1.5621, which seems to be the correct drivers for my machine, a Mac Pro mid 2010. The 5.1.5640 drivers are for 2013 macs. I tried downloading the 5.1.5621 software manually and running it once Windows loaded, but I got the same problem.
The error message that appears in step 11 is "kernal_security_check_failure" This seems like it might be related to Yosemite. Doesn't Yosemite now have some security feature related to ktext files? I am getting this from Trim enabler.
Thanks
Ciro

Windows Vista Boot Camp - No Audio (sound)

Hi Guys,
I just got my father's Macbook Pro he bought last year for christmas, and I was already excited how I could actually have both Mac and Windows on one laptop (as I need Windows for making music in Fl Studio). Now the problem is, that there is no Sound coming out of the MBP when in Windows, and there is the infamous red light coming out of the Headphones Jack. I'll explain everything I did in steps so that you get the idea. So first of all, I started with the Bootcamp Partition and Installation. Since I lost my Mac OS X (or tbh my father lost it ) I was happy to see that I could actually download the 'support software a.k.a. Drivers' directly before the installation. Well, guess what, It didn't work because the 'support software was not available'. Anyways, I proceeded with the Installation as if I had the CD and Drivers ready. Everything went fine, after booting to Windows I installed Bootcamp and the drivers (Since I found someone posting the .Iso file of the contents of the MAC OS X CD I lost, so I downloaded it.), I was excited to see that every button on the keyboard worked and also the trackpad worked almost flawlessly.Now after the Installation, I did some Windows updates, and then I wanted to listen to some Music, and suddenly I realized that my Sound isn't working! And the Jack started to Glow Red.
So I went online, in search of the problem. I found various 'fixes' for the problem, such as installing a Cirrus Driver (well that didn't work, as it said that my windows is in Slovak and that's not a supported language... what the ****?), then I tried to install Realtek Drivers - didn't do anything (although I didn't uninstall the old ones, because I wasn't sure how exactly to do that.)... Well I think it might be helpful if I'll just summarize what 'fixes' I tried:
Update to Boot Camp 3.1 - Didn't work
Update to Service Pack 1 or later. - Updating to Service Pack 1 and then 2 got rid of the red light, when there is no sound output, as soon as I try to play something it's back on, glowing like a Christmas Tree
Try to wiggle a toothpick in the headphone jack - amazing fix, isn't it? Well I actually found out that It worked for some people, and since I'm desperate, I tried it... As expected, it didn't work.
Install Realtek Drivers - as mentioned above, didn't work...
Install Cirrus Drivers - Slovak Language not 'supported'... right.
Update Boot Camp to latest update - Didn't Work...
Install a 32 Bit Version of Windows - I didn't mention this, I had first a 64 bit version of Windows 7 Installed, and the sound didn't work as well. As there was some problem with the Boot Camp installation, I tried to reinstall to 32 Bit, But used Windows Vista instead, because I heard Windows 7 Is 'not yet supported' or something..
Make sure the Speakers are 'preset' as a default device in the Sounds Control Panel - It Already was preset -.-
'Rage Plug' the computer and hope for the best...? Yeah.
Can anyone finally tell me how to fix this, I am desperate, tired, angry and all the other negative emotions you can imagine right no, because I spent hours on this, looking up millions of forums, in which there was no answer for me!!
Please.
Thanks.

Welcome to the Apple Support Communities
You have to download the drivers. To download them, press X key while your Mac is starting to start into Mac OS X, open Boot Camp Assistant and follow the steps to download them. You will have to burn them onto a DVD or USB drive, so you will be able to install the drivers on Windows. Then, it should work fine.
If you can't download them in Boot Camp Assistant, download the drivers from this website > http://www.cafe-encounter.net/p682/download-bootcamp-drivers The links are from Apple and that's safe to download and install

How can I install windows 7 using boot camp, if the partition will not format correctly?

Hi All,
I'm new to this forum and have had a chance to look around a little bit, but haven't really found an answer to the problem that I'm having.
I have an imac and I'm attempting to use boot camp. I have used it in the past, with prior versions of mac os x, but this is the first time that I have tried it with 10.6.8. The first thing I found out is that I can't use Windows XP, even with service pack 2 installed, because it doesn't find the "boot camp" partition. So, I recently obtained a full retail copy of Windows 7 and have been trying to install it. I have no problem with the boot camp assistant creating the new partition, 200 GB. However, when I insert the Windows 7 DVD and the computer restarts in the Win 7 install screen it tells me that I cannot install Windows on the selected partition (which I expected to see.) So I choose "format" the further format the partition. It doesn't ask me how I would like to partition this, but just seems to start. All seems to go fine until it finishes and i see the same message of "Windows cannot be installed in the selected partition." I can click on the format tab endlessly but it still doesn't seem to work. Does anyone have any ideas? I've called Apple and their technicians keep telling me that I need to reinstall the Mac OS again, which I've tried. It doesn't seem to help either.
Thanks in advance for your help,
DTK

Yes, I choose "Format" under the advanced options screen. It seems like it formats, but then I get the same message of "Windows cannot be installed to this disk. The selected disk is of the GPT partition style." I can continue to click "format" but i keep getting the same error.
There is the answer, right in front of us ....
Delete the bootcamp partition and start again the correct partition type is GUID but BootCamp should take care of that automatically so try again.
