Bootcamp Assistant Stalls on restart after partitioning

Ok so i had some problems with my windows install and i wanted to update to Mountain Lion. I wiped my entire hard drive, deleted all the partitions, and started fresh with one partition. I got Mountain Lion installed perfectly. Heres where the problem starts. I started with editing the plist to make bootcamp allow USB install. (im running an Imac 2007). The Superdrive only works when it wants to and its easier just to not use it at all. I then opened bootcamp assistant and checked all three boxes (created usb disk, download support drivers, and install windows 7). I used my handy .iso of my win7 x64 disk and bootcamp created my usb disk, downloaded the support drivers then asked me how big to make my partition. i choose the size and clicked continue. Bootcamp partitioned my drive just fine and then restarted. And then my computer sticks at the apple logo (with no spinning wheel). i let it sit over night and no difference. so i just powered off and when i powered on i get the *no boot disk -- insert bootable disk and press any key*. The USB flash drive is in the computer but its not showing up after a restart and holding alt. i can boot into OS X just fine but not get windows to install. The bootcamp partition shows up on my OSX desktop with no files. Also the USB disk shows up named WININSTALL with the install files and support drivers on it.
Any help would be appreciated.

Is your external DVD drive an Apple drive, or a third party drive? I Not all third party drives provide full boot support in their hardware, so that could be the cause of your problem. Since you have a MacBook Air, it should support booting from a USB stick with your Windows installer on it. You might try that.

Bootcamp assistant doesn't restarts to the Windows installer. Macbook pro 13" (early 2015)

I'm trying to install windows 8.1 on my new macbook pro 2015, things are good until I got to the point after I chose the size of partition then mac restarts. It supposed to reboot to windows installer as described in step 4 below, but it boots into mac.
I was able to install the windows to my macbook air before without a problem, hope someone could suggest what I did wrong here.
Followed exact steps from here - How to install Windows using Boot Camp - Apple Support
1. Check System Requirements
Some versions of Windows require a certain processor, and more hard drive space and memory (RAM) than others. Check the documentation that came with your copy of Windows to find out what you need. Then use System Information to see what your Mac currently has.
2. Create a disk image of your Windows disc
When you purchase Windows, it either comes as a disk image file (ISO) or as an installation disc. If your copy of Windows came on a DVD, you should create a disk image of your installation disc.
3. Open Boot Camp Assistant
Boot Camp Assistant walks you through installing Windows on your Mac. Open this app from the Utilities folder in the Applications folder and follow the onscreen instructions to automatically repartition your startup disk and download related software drivers for Windows. When prompted, connect your USB flash drive.
4. Format your Windows partition
When you complete the assistant, your Mac restarts to the Windows installer. When you're asked where you want to install Windows, select the BOOTCAMP partition, then click Format.
5. Install Windows
Follow the onscreen prompts to finish your Windows installation.
6. Restart your computer
After Windows is installed, you can switch between OS X and Windows. Use the Startup Disk preference pane in OS X, or the Boot Camp system tray item in Windows to select your startup disk, then restart your computer

Ok, I finally got the problem solved. It didn't mention anywhere that I have to restart and holding down the 'option' key, then go to EFI boot... hope it'll help someone with the same issue.
Cheers!

My MacBook Pro encounters an error when partitioning for loading windows using Bootcamp Assistant. I deleted the partition that was there in order to upgrade to Bootcamp 5 but now I am struggling to get Bootcamp 5 to complete the job. Help please.

I am struggling to Partition my MacBook Pro using Bootcamp 5, can someone help, please. I previously had successfully loaded Windows 7 running Bootcamp 4 on the same machine. When I upgraded to Windows 8 I started encountering problems. My trackpad would not work and it required me to load Bootcamp 5" as I was running 32 bit this is not supported by Bootcamp 5 I had to completely delete the previous partition, but now I can't repartition as it goes halfway and says an error has been encountered and Bootcamp cannot partition this drive.
I do not know how to defragment the drive in Apple as I can in windows nor can I clean it up to maybe get everything in neat clusters, maybe somebody can help me solve this problem.

Sorry Bobthefisherman, this was not helpful. I had already gone through these pages before coming to you. What I have discovered however is that when Bootcamp Assistant deleted the partition, it did not create a single volume but created three partitions instead which maybe the reason why it cannot create the new part ion parameters I am asking it crate. So I took it to the geniuses at Apple who suggested that I reformat the drive and reload everything again! and this might solve the problem. We'll all know whether this is helpful once it finishes the formatting of the hard drive. This process is taking a very long time to complete so I am leaving it overnight for it to complete. I will keep you updated on progress. I am also told that Apple is struggling with Windows 8 drivers and I may not be able to use that, so I am going back to Windows 7 even though I was beginning to like windows 8 very much.

Bootcamp won't install windows after partition

I am attempting to install with windows 10 preview via bootcamp. I've had it running in Parallels just fine but want to run it using bootcamp and then run the bootcamp partition through Parallels.
I went through the bootcamp assistant, made the bootable usb drive with the drivers and then went to partition the drive. Once the partition finishes, the Mac reboots with no warning. It reboots right back to the login screen for mac. If I go to the disk utility I see the BOOTCAMP partition there.
Tried rebooting holding the option key and the only option is the Mac, no Bootcamp partition. I've tried deleting and re-creating the partition and it still isn't available as a boot option.
How do I fix this?

Frozen on restart after partitioning

I am installing Windows 8.1 on an iMac running Maverick. After going through the partitioning sequence the machine automatically restarted and now shows a gray screen with a 'forbidden' circle with diagonal slash throough it. the loading cogwheel has been running for 15 minutes with no sign of anything happening.

This probably won't help if it was actually a glitch in the download, but you could try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up in Safe Mode, try to restart normally, and go to Applications > Utilities > Disk Utility.
Select the named boot volume in the left sidebar, and repair permissions on it.
See if you are able to do some hard drive maintenance to help things out.

Migration assistant stalled ( 110 hours, after 30 hours ). How else can I transfer my data from PC to new iMac without wireless migration assistant?

i am a new mac user
i have a new imac
was trying to transfer data from old pc to imac using migration assistant ( wirelessly )
i had done it once already, but i noticed that although it took about 8 hours, very little data from the c drive was actually transferred ( i had not noticed i had to designated folders to copy )
so i did it again, targetting folders on the D drive and my external hard drive F - lots of data ( about 300 GB )
after an hour i noticed that the estimated time for completion was 88 hours ! i did let it run for about 30 hours anyway and hoped for the best ...
this morning when i woke up the time remaining was estimated at 42 hours, but then it suddenly jumped to 110 hours !!!
when i came home 8 hours later, it was still at 110 hours, so i stopped it - i assumed it had crashed ...
i got a message that one folder on my pc might have been lost - corrupted
incredibly, after more than 30 hours, no data had actually been transferred to my new mac !!!!
in any case, i see now that migration assistant created a new user account anyway, which i do not want
SO
how can i transfer data from my pc laptop to my new imac, preferrably with a direct cable connection as opposed to wireless, directly into my main account
and i how can i delete the other account migration assistant created in the initial "successful" transfer
thanks
chris

Ah yes, forget the Firewire cable then, use ethernet.

Computer stalls on restart after ONYX

My friend has a 24" 2.4g iMac running 10.5.8
I recommend Onyx to him and he downloaded, installed and says he ran maintenance. Then went to restart. computer chimes, apple logo, exactly 3 revolutions of the gear and then freezes.
Apparently there is a disk in the drive and we've been unable to eject. When holding down mouse button, eject or option, computer shows only a blank white screen on startup.
Need some help with ejecting disk to try and boot off DVD and possible solution as to why it won't reboot after running ONYX

Tried reset of PRAM...called Apple support and spent 30 mins online with young (very) man who gave up after trying several trouble shooting steps....
Starting up with command, option, p, r results in just a blank illuminated screen...pressing any key or clicking mouse on start up results in same screen....pressing nothing results in the logo gear scenario....

Bootcamp will no longer boot after deleting partition #3 of my new Mac Mini. What happened? Was it the way I tried to reclaim the HDD space for Mac?

Here's my dilemma. I have a new Mac Mini - a week old. I installed Windows 7 on it using Mac's Bootcamp assistant. I then set up and configured my Windows 7 world and everything worked fine. No issues logging in between Lion or Win7 via the restart/option key procedure. Well, yesterday I split my Mac HD partition one more time to create a third partition (was created as an "extra", e.g. possible future partition for another operating system). After creating it, I then decided that I didn't really need it. So I deleted it in Disk Utility and attempted to drag the Mac HD partition line downward so as to "fill in the gap" and reclaim the lost hardrive space. It seemed as if I could reclaim about 1 gig or so, but I figured...oh well.
Well, the Mac HD partition seems to work just fine, but now I've noticed that I can't get into the Bootcamp partition anymore. It wont boot. If I try to verify the partition [doesn't even give me "repair" as an option), then it fails and gives me the following error message: "verify volume failed. invalid request." When I go to the Startup Disk option in my System Preferences section, it displays the bootcamp partition as a folder and not as a drive anymore.
I'm assuming that I messed up some permissions or lost some vital links during my attempted resizing/reclaiming of harddrive space. How do I fix this without having to reload either all of my Mac info or all or my Win7 info? I'd hate to consider the last two days of my life loading this crap up a complete loss.
Thanks in advance!

Thanks for checking in, BDAQua.
Problem solved.
In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
"If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.
Gratefully,

Error in Restoring the HDD partition using BootCamp assist

This is regarding error in restoring the HDD partition using BootCamp assist. Yesterday I was trying to instal Windows 8.1 Pro on my Mac Mini.
Started had installing windows software using Boot Camp assist using the USB flash drive
Took the back of Windows Support software from Apple store
Did the HDD partitioning for Windows,
Then went ahead to install the windows and automatically machine restarted.
After few minutes started installing Windows... and stuck for more than 3hrs at by displaying the blue screen of Windows installation... and inactive
I had restarted the using start button, and finally I could not able to install Windows.
Then I got black screen with message ' No boot disk, please insert boot the disk and press any key to restart'
I have restarted using start button by holding 'Alt' key
Finally I could able to started machine with OS X
Now I wanted to remove the partition created above, using Boot Camp assist, but it is not able to do it. There is error message ' Error while restoring the hard disk'
Any help, how to remove this partitioning? Also in every restart I need to hold 'Alt' key to boot the machine with OS X.
-Narsimloo Begari

if you've tried and cannot remove the partition with boot camp assistant, you'll have to open disk utility and reformat the partition there - choose mac journaled and then try to combine this partition back into your existing Mac partition

IMac continuously restarts after bootcamp failure

Hi, I hope I'm posting this in the correct forum!
I've just done a fresh install of OS X Snow Leopard on my 2 and a half year old iMac. (I wanted a clean HDD before going back to Uni), I installed all my software and finished up by trying to install Windows 7 Home Premium via bootcamp. Bootcamp partitioned the HDD and restarted with my legitimate Windows 7 disk in the drive. But now it doesn't start back up! Just a white screen for 10 minutes or so then it restarts again.
The only way I can get onto my mac is by holding down the alt key as it tries booting up and it lets me select my Mac HDD. That's the only one it shows. I remember having the same problem at the start of the year, so a fresh install of Snow Leopard should fix it, I know. But I've just done this once and it took all day to sort of my programs! It'd be a hassle to have to go through it again, is there anything else I can do?
Thanks.
Edit: I originally set 60GB for Windows, after that failed I erased the partition and tried again with the default 32GB. None of these attempts worked and after erasing the windows partition a 2nd time, it still doesn't start up properly. (My iMac is a 20" intel model) Thanks again

Hi,
to avoid the neccessity for the useage of the Option-key got System Preferences in OSX - then Startup Volume and set your OSX to be the Default Startup Volume.
After that your Mac should start automatically in OSX on the next reboot.
Then you can/schould use the BootCamp Assistant again to revert the done partitioning back to one single OSX partition.
Refer to the BootCamp Installation Guide.

The guide to bootcamp assistant states that bootcamp can only be installed on a drive with a single partition. New Macs with Lion preinstalled have two partitions - the second is a recovery partition. How do I install Bootcamp?

Late in August 2011 I took delivery of a new 27" iMac with Lion preinstalled. I need to run Windows as well. Following Apple's written suggestion, I printed off the then current 12 pages of the document "Bootcamp Installation & Setup Guide" which clearly stated that the hard drive you were going to install on had to have on it, before install, a maximum of one partition. Using finder and disk utility I determined that there was only one partition. Unbeknownst to me, there was (is) an additional hidden (from those two pieces of software) partition on the disk. As of machines delivered new with Lion preinstalled, Apple has begun to include a "recovery partition". In that partition there is a copy of the software necessary to reinstall Lion via a download from the Apple App Store. Not knowing the partition was there, I cranked up "Bootcamp Assistant" which nicely offered to repartition my hard drive creating a "Bootcamp Partition" in addition to the existing. I told it how big to make each and hit the do it button, subsequently destroying my operating system. Oh, it very nicely told me, after the damage was done, how many partitions were REALLY on the disk and that I could not install Bootcamp cause there were too many partitions.
Luckily the the Recovery Partition, which at that point I knew existed, was not harmed and after doing some research on another compter, I used it to once again download Lion from the App Store and reinstall. So, I have recovered but am still stuck with the problem: how do I install Bootcamp in this new environment?

First you need to seriously back up your Mac.
A clone is an exact duplicate of your existing Mac HDD. Merely copying and pasting a drive will not make a bootable backup. In case of problems you can boot from an Ext HDD clone and use the utilities to repair, reformat, or clone the Ext HDD back to the internal Mac HDD. While Time machine back ups are easy you can not boot from it. The best thing to have for any kind of problem is a bootable clone backup on an external drive. Some even have two external backup drives in case one fails. There are two good apps for cloning named SuperDuper and Carbon Copy Cloner.
In dealing with the recovery partition a simple approach is to clone the Mac partition to an external disk then re-partition the Mac to a single partition (GUID partition table) . Then clone the external disk clone back to the Mac. You will now have only one Partition and Boot Camp assistant sould not object.
Some have recommended getting rid of the recovery partition while others have advised not to do this. If you have the Lion USB Thumb Drive you do not need a recovery partition so can discard it without concern. There is another way to get rid of the recovery partition if you decide to do it but first be sure to have a backup of your Mac ( I know I sound like a nagging mom but many dead computers have been saved by this simple precaution).
Use Disk Utility.
1) Make the Recovery visible in Disk Utility by using a program like Secrets:http://www.macupdate.com/app/mac/27025/secrets or MacPilot:http://www.koingosw.com/products/macpilot.php (15 day free trial).
2) Highlite the Recovery partition and Control click it and select Mount the partition.
3) With the Recovery partition highlited, erase the partition, you'll get an error message, ignore it.
4) Now highlite the top identity of the hard drive and select the partition tab.
5) Highlite the Recovery partition and press the minus sign.
6) Click and hold on the bottom edge of the partition above and drag it to the bottom, if it doesn't go there automatically, the press apply.

EXTREME lag after installing Windows 8.1 pro via / Bootcamp assistant

Hey guys, today I've literally been through **** trying to get this game working on my MacBook Pro.
I've basically gone out & bought Windows 8, created a partition on my hardrive (of my MacBook Pro) & installed it into that partition using Apples 'Bootcamp assistant'. After installing the operating system I also loaded the drivers which were given to me by Apples 'Bootcamp assistant'.
I now have the game on the Windows 8 (on my MacBook) which is a £2000 machine... I have got to the menu & experienced extreme lag to the point where I've even managed to turn down all my video settings & it is still lagging a lot despite my high-end computer hardware - here is my computer http://store.apple.c...B/A&step=config#
I have tried running the game on this website http://www.systemrequirementslab.com & everything is great but it says I don't have the required 512MB of video RAM... It says I have 256MB. This is complete ********? I believe I have 2GB of GDDR5 video RAM. It also says that my graphics card is called 'Microsoft Basic Display Adapter'. So I believe this is where the issue lies. My theory is for some reason one of the drivers which I have installed which was given to me by the Bootcamp assistant is messing with me.
This is literally all the information I can possibly provide, does anybody know how I could fix this?
Thanks you!

If the underlying hardware was exposed correctly by the CSM-BIOS when Windows was installed, your Device Manager should look like this.
If the Windows installer did not see any devices as your screen indicates, Windows will use generic software-based drivers which will be very slow and painful.
Rudegar ... I think the Windows installer did not see any hardware, otherwise there should be HW with yellow triangles with exclamation marks.

Can't partition HD with Bootcamp Assistant on brand new iMac

I just got a 27" 1TB brand new iMac three days ago. After copying over all my files from my previous computer (PC), installing some software packages and configured the Mac the way I want it, yesterday I wanted to partition 80GB out of remaining 330GB with bootcamp assistant to install Windows 7. After one hour it stopped with an error message that it wasn't able to move some files and I would need to re-format the HD and start again.
Is there really no other way? It took me two days to get to where I am.

It should only take less than a minute.
So just use OS X software to clone what you have to another hard drive, then do an erase and restore.
And backup before starting is at the top of the list of things to do to prepare.
http://www.apple.com/support/bootcamp - re-read the pdf guide linked at the top and other tech articles.
And you really do want bootable clone image of Mac OS anyway, in addition to or in place of TimeMachine, so no loss in doing so. It isn't as if you will lose or have to redo.
It needed contiguous free space and no files at the end of the disk. But installers and updates do scatter files and fragment free space a lot and can leave files locked where they can't be moved.
SuperDuper
Carbon Copy Cloner
iDefrag
iPartition
Apple Disk Utility Restore
And you can have OS X on multiple hard drives, plus it really helps for doing the type of maintenance and repairs needed for updates and proper running.

I'm trying to install windows 8 on mac, but after partitioning and restarting, it stucks on blue logo and i waited 20 minutes but nothing happened, what can i do, please help.

I'm trying to install windows 8 on mac, but after partitioning and restarting, it stucks on blue logo and i waited 20 minutes but nothing happened, what can i do, please help.

I think there's some remmants left over from when Apple transferred stuff over. We can try a quick fix, but if that doesn't work, I think the only option is to clean install OSX and then install Windows.
open disk utility, confirm that you only have 1 partition (mac journaled)
restart and PRAM reset
open disk utility and repair permissions twice
restart boot camp assistant
Does it work?
If not, I would boot holding command+R, choose disk utility from the menu and completely erase your HD (formatting it as mac journaled again). Then, install OSX on this HD. Once OSX is installed, don't copy your files over from the backup yet. Instead, start boot camp assistant and see if you can get Windows installed. You can copy back your other files after we get Windows installed.

Problem after the uninstall of windows with the bootcamp assistant!!!!

I have too problems: The first is my bad english i like to excuse for that. I hope you can even so understand my main problem. I try to describe it to you: I install windows on my mac. After a short time i decide, i don't like it and i uninstall it with the bootcamp assistant. Than i want to start my mac but it didn't work. My mac want to start windows even though I install windows.
I think there is something that isn't uninstall but i don't no where and what i can do against this problem???

If you can't boot into OS X, then hold down the Option key on startup, and select your OS X partition.
After that, do what the above poster said, so that the Mac knows to always boot to that volume.
