Boot Camp 4 to Boot Camp 3

How to move from BootCamp 4 BootCamp 3?

Downgrade from Lion to Snow Leopard.
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

How to undo boot camp, wont boot from install disk in dvd drive

A few months ago I went through trying out boot camp and parallels. Now, I think something is messed up. I dont need either right now, so I just want to wipe out the whole system, repartition the drive, and restore to a blank new install of os x 10.5 leopard.
But when I put in the install disk, it wont boot up off it.
I tried holding down the c key while powering it up, and it just cycles through: hearing the drive whirl, a bling sound, and then repeating it again while the screen is blank. Finally, I held down the click button on the touch pad so it would eject the install disk.
Maybe this will help someone recognize part of the problem. Ever since messing around with boot camp and parallels, my machine wont "reboot". To reboot it, I tell it to reboot, then it hangs on the star like screen, then I have to hold the power button down, then if I do nothing, it tries to boot, but ends up in a dos looking screen saying no bootable device. So when I power it back up, I hold down the alt key, and then I have one choice: the hard drive. I pick that and it boots up ok.
So... I thought, well, maybe the boot camp is still messed up; maybe I should undo boot camp. When I start the boot camp assistant, there is only a "partition" and "back" button; nothing to "restore" the hard drive to just one partition.
What can I do? I want to wipe the drive and install a fresh install from my install disk.

Can't boot windows - select boot disk and computer goes to sleep

I've got a Mac Pro 3,1
I've had windows 7 installed on an IDE hard drive in the CD bay.
Lately, I was getting BSODs, so I decided to reinstall - I reformatted the hard drive and I'm trying to move forward.
I haven't been able to boot any kind of windows installation disk! USB, DVD, anything!
I select the boot disk on boot up (hold option, select the windows install) and the computer seems to boot (shows the bootcamp logo) then just goes black (like it's sleeping - monitors off, not an 'active black' screen) There is no hard drive noise - this thing is basically off.
I've tried using rEFIt, using different USB drives, DVDs, everything. I can get into rEFIt, select the boot disk - and it's the same problem. Windows won't boot!
What gives? I've had no luck looking online for this issue. Some folks have a 'black screen' with an iMac - but this isn't a driver issue - the computer is not booting!

never mind, I changed the connection to a different usb port and problem solved. Thanks anyway.

I tried installing Windows 7 using Boot Camp, but it didn't work, I don't know how to "unparticion" the memory I gave to Boot Camp, and Boot Camp "vanished", help...

I tried installing Windows 7 using Boot Camp, but it didn't work.
Although it didn't work, the memory is still divided. So I looked for Boot Camp in aplications, but it literally vanished...
So I tried downloading it again, but I only found EXE files... they don't work on my MacBook Pro...
It's very new... Bought it recently...
Please... I need help to unparticion memory back to original Mac HD and install Boot Camp...
Thanks...

Below is the paragraph from the instructions. Follow it exactly and then report what happens at each stage.
How you remove Windows from your computer depends on whether you installed
Windows on a second disk partition or on a single-volume disk.
If you installed Windows on a second disk partition: Using Boot Camp Assistant as
described below, remove Windows by deleting the Windows partition and restoring
the disk to a single-partition Mac OS X volume.
If your computer has multiple disks and you installed Windows on a disk that has only one
partition: Start up in Mac OS X and use Disk Utility, in the Utilities folder, to reformat it
as a Mac OS X volume.
To delete Windows and the Windows partition:
1 Start up in Mac OS X.
2 Quit all open applications and log out any other users on your computer.
3 Open Boot Camp Assistant.
4 Select “Remove Windows 7,” and then click Continue.
5 Do one of the following:
a If your computer has a single internal disk, click Restore.
b If your computer has multiple internal disks, select the disk with Windows on it,
and then select “Restore to a single Mac OS partition” and click Continue.

Windows will not boot to my boot camp partition on a DIY fusion drive - gives "No bootable device found" error

I have a MacBookPro 9,1 (mid-2012, non-retina) running OS X 10.8.2. Here is what I have done to my system:
Installed Windows 7 x64 Pro to a boot camp partition; installed all windows updates.
Using WinClone, save an image of this boot camp partition.
Removed optical drive and HDD.
Installed HDD in place of optical drive.
Installed SSD in place of HDD.
Booted to recovery partition, installed OS X on a flash drive.
Booted to flash drive, created fusion drive using [MacWorld's instructions](http://www.macworld.com/article/2014011/how-to-make-your-own-fusion-drive.html)
Booted to recovery partition on flash drive.
Restored system to fusion drive from a Time Machine backup. Unfortunately, it seems that because I never installed OS X on my fusion drive, I do not have a recovery partition. But that's an issue for another day.
Using Boot Camp assistant, created a boot camp partition on my HDD.
Using WinClone, restore my Windows installation from the previously created image.
Now, Windows boots to a black screen telling me that it can't find a bootable device. I have tried a few things to resolve this, all without effect:
I know that VMware Fusion has to prepare a boot camp partition in order to virtualize it, so I figured it might inadvertently fix things. Alas, while it *did* successfully boot my boot camp partition into a virtual machine, I still can't boot into Windows.
I figured I'd just try to reinstall Windows. Surprisingly, my system booted to my Windows install disc, which was in my original optical drive (which I had put in a USB case). But, Windows refused to install, giving me a an error 0x8030024. It seems the solution to this issue is to disconnect all drives but the one on which you want to install Windows, which is something I would dearly like to avoid. It would be a pain, but more than that, I'm afraid it would bork my fusion drive, even if I'm careful to never boot to OS X with the SSD disconnected.
A lot of places said that this error results from a borked MBR, and suggest using a tool like gptfdisk to rewrite it. I followed the instructions [here](https://discussions.apple.com/thread/4144252?start=0&tstart=0), but *that* didn't work either.
I am now completely at a loss as to how to proceed, and Google isn't much help either.
In conclusion, here is some information that you may find helpful:

My setup is very similar to your's, Ryan, on a Mac Mini5,2 and the ordering is different and Winclone was not used.
1. New Mini with internal 500GB with Mountain Lion(ML), put into an external FW enclosure, so the Mini can/could be booted using an external drive for contigency.
2. Replaced internal stock HDD (500Gb/5400rpm) with SSD/HDD (256Gb SSD/1TB 5400rpm).
3. Installed W7 x64 on 64GB partition on HDD, which was a single-partition drive to begin with.
4. The remaining HDD partition and the entire SSD was put into a Fusion drive.
5. Using Command-R, new ML installed on Fusion HD.
Here is what I currently have...(Disk0 - SSD, Disk1- 1TB HDD, Disk2 - Fusion, Disk3 - External FW).

Need help with Boot Camp dual booting

I'm trying to install windows 7 on a separate partition but after the mac book pro restarts to start the installation it says windows can't be installed because it needs to be NTFS format
but the mac partition is Mac OS Extended(journaled) but gives no option to format the other partition as NTFS
what to do?

I assume you did not use Boot Camp Assistant to create the Windows partition? If you did and are in the Win 7 installer you should be looking at a display of all the partitions on your hard drive. Locate the partition you allocated for Boot Camp (you should know it by its size and/or it has the volume name of BOOT CAMP. Select the volume then click on the option to Format the volume from the group of options at the lower part of the display. If the option is not active then with the volume selected click on the Delete option. Refresh the display then reselect the now unallocated volume and click on the Format option.
If none of the above work then reboot. When you hear the chime hold down the C key and wait until the computer starts up from the Windows DVD. When you reach the same point as above locate and select the unallocated volume for Boot Camp. Click on that Format option.

Mac Book Pro (2012) tion not booting after installing boot camp

On Sunday I installed windows 8.1 on a partition that I made using boot camp assistant. It worked fine after I installed windows yestarday. Today when I turned on Mac Book Pro and booted it up from the OSX Mavricks partition it turns on but after I hear the start tone, I see the apple logo, a progress bar and then a couple seconds later I see the spining gears and then my computer shuts off. I tried booting the computer up from the windows partition and that worker fine. I tried booting it up from the mac OSX parttion and same thing again. I tried pressing Comand R on start up to go to disk utility so I could verify the Machintosh HD disk. It said that it needed to be repaired but when I went to go repair it I get an error message saying " Disk Utility Cannot repair this disk... back up your files." Next I try going in to single user mode and I type /fsck -y this does not work either. I tried booting into safe mode but that did not work. What should I do next?

Hello Jack Ryen,
Thanks for using Apple Support Communities.
From your post I see that your Mac will not start up in OS X, and the result of you verifying the disk indicates you need to back up your files and reformat. As Disk Utility states, the next step for this issue is to backup and if possible reformat the drive.
Important: If Disk Utility is unable to repair the internal drive, you should back up your important data immediately and if possible, reformat the drive. Consider bringing the Mac to a Genius at an Apple Store or an Apple Authorized Service Provider for further diagnosis. Be sure to ask that, if the drive needs reformatting or replacing, they contact you about escalating your case to a special data recovery service. If you plan to visit an Apple Retail store, you can make a reservation (available in some countries only).

OS X not booting after installing Boot Camp Windows 8

Hi all,
I installed Windows 8 with Boot Camp Assistant however I couldn't boot into OS X anymore. I get a prohibited sign on boot. If I press Command+V on boot it says "Error loading kernel cache (0xe)". Windows 8 can still boot without problem. Are there any way to solve this problem?

I am also facing the same problem but didn't find solution yet. When I give repair disk it say "the partition map needs to be repaired because there's a problem with EFI system partition's file system".
And I don't have windows installed as well.

Boot options duplicated; Boot Camp Assistant newly non-functional

Short version:
1. Up to tonight, my hard drive was encrypted using PGP Whole Disk Encryption -- secure boot and all. Had Boot Camp working fine with it.
2. Attempted to install OS X 10.6.5 despite PGP warnings to decrypt first. Ended up with an unbootable OS X partition. Decrypted drive in Windows, got back into OS X.
3. Disk Utility returned a few errors on OS X partition. Quickly fixed those by booting from Snow Leopard CD and running it.
4. What I'm now noticing is that when I hold down the option key, I'm given duplicate options. Instead of "OS X Partition Name Here" and "Windows 7 Name Here", I've got a duplicate for the former. So my options are "OS X", "OS X", or "Windows".
5. And, when I try to run Boot Camp Assistant out of curiosity, I'm told that I either need one big non-partitioned drive, OR existing partitions created by Boot Camp. I already did that.
Any thoughts on fixing #4 or #5? Resetting PRAM doesn't help. Windows does not show as an option in "Startup Disk" in system preferences. But the Windows partition boots just fine when holding option on restart.

And since I can't edit my original post any longer, here's what fixed the redundant boot option thing:
http://hints.macworld.com/article.php?story=20091111185717745
Worked like a charm. Fixed the duplicate "OS X" option on boot, and both OSes boot normally. Can now click past the first few options in Boot Camp Assistant, so I'm assuming that's working normally now also.
Still no Windows option in Startup Disk, but apparently that's related to my use of NTFS-3g? Thought that was fixed.
sudo fdisk /dev/rdisk0 is now:
Disk: /dev/rdisk0 geometry: 30401/255/63 [488397168 sectors]
Signature: 0xAA55
Starting Ending

4: 00 0 0 0 - 0 0 0 [ 0 - 0] unused
Only thing I'm worried about now is whether I might have damaged any files though any of this crap. Don't know if I can check for that, or if I should worry about it.

Leopard always boots into Safe Boot

Every time I restart Leopard it boots into "Safe Boot" mode. To get it to boot into regular mode I have to keep hitting "x" after the startup sound while booting.
I read that Leopard shouldn't boot into safe mode unless I hold down the shift key when starting up. My shift key isn't stuck down (I wouldn't be able to type this message in lower case if it were). But Leopard insists on booting into safe mode by default.
I applied the latest updates just this morning. So everything is up to date.
What can I do to get Leopard to boot by default into normal mode again?

Maybe I need more specifics. I clicked on the Apple menu in the topbar and clicked Restart. I then clicked Continue when prompted to restart immediately. I then held down the Command, Option, R and P keys. While holding down the keys I heard the startup chime once (not twice) and my computer started normally.
I'm wondering if I did the right thing since I didn't hear the second startup chime.
Did I miss something?
Thanks so much for your help.

Error "Can't find boot device by boot options" when boot from ISO via AMT

Hello.
When I try to boot from ISO CD via AMT I got an error message:
"Can't find boot device by boot options"
Settings are similar to what I made in HP 8100, 8200 etc - SOL/IDER/KVM, network access enabled
Where could be a problem?
Prod. name: HP Compaq Elite 8300 Microtower PC
Prod. number: B0F41EA

Just wanted to follow up with this as I got a response from HP. It looks like it is at least the 2.9 BIOS version that has this issue. I know that at least the 2.51 BIOS version is unaffected.

Slow boot after failed Boot Camp

Hi,
I have an iMac, where I installed a SSD in a Thunderbolt enclosure and booting OS X from it.
That made it insanely fast :-)
Now I tried Boot camp to install Windows on the internal HDD which failed. Seems to be a known problem when using Thunderbolt as bootdevice…
After this, when I boot, the system hangs about 20 seconds, before OS X boots (Apple logo with the line moving). Just black screen before the Apple logo comes.
Seems the system is trying to load a not existing Windows…?
Formatted the internal drive, but it didn't help.
How do I stop this delay?

IMac randomly booting into "safe boot" mode after a clean installation of OS X Lion 10.7 (??)

Is anyone else having problems with their Mac (running a clean installation of OS X Lion 10.7) randomly booting into "safe boot" mode after a restart or shut down?
(Indicators being: seeing the login screen even when "automatic login" is enabled, the proper video drivers not loading - indicated by laggy desktop animations, WiFi not working properly, Menu Bar icons that normally show - not showing, etc.)
**Note: I migrated from a Snow Leopard Time Machine backup, but did not import "Settings". I thought this would be the best way to keep from encountering any issues with 10.6/10.7 incompatibility.

Found this answer from another user. THE EXACT THING HAPPENS TO ME:
Its really annoying Apple hasn't fix it.
=================
I think i got it :
The progressbar while booting ( booting in safe-mode ) came from the wireless keybord and is reproduceable.
At evening I shut down my iMac an put off my mouse and keyboard. To startup I put on the iMac and immediatly after I switch on keyboard and mouse. In tihs case the keyboards sends some event wich leads to safe-mode.
Know I wait until I switch on the keyboard. In my opinion this is a bug, i can live this way but i hope it will be fixed.
I will know take a look at it while not switching off the keybord, power consumption should be acceptable

Boot Camp Vista : boot with Numluck on ?

I'm running Windoze vista via Boot Camp for gaming purposes.
I have all the latest Boot Camp drivers loaded.
I noticed that the numeric keypad on the Mac keyboard is not activated (numlock off) after boot.
Is there a way I can force the numeric keypad on after boot without having to do it myself every time ?
Thx,
Tom.

I have not tried this myself using Vista but various threads on the web say this is also suppose to work with Vista.
