Windows 8 installer doesn't want to format the boot camp partition

Hello,
I followed this instructions : http://www.pocket-lint.com/news/45898/how-to-install-windows-8-on-a-mac
All works but the installer doesn't want to format the boot camp partition, i click on "option" > "format", i wait like 3-4 seconds (so not enought to format 100Go) and then same error "Windows can't be installed on this partition".
Any idea ?
I have :
Macbook Pro 15'' 2,4 GHz Intel Core i5
Mac OS X v10.7.5
1 Drive : 320Go
1 USB KEY that i used to install osx lion, so i think it's not the problem.
1 Windows8 64 downloaded from my university, and it works on a PC.

I have the same issue. Dec. 2013 13" macbook pro with 1tb ssd. Windows 8 Pro (have the box/cd).
Why is it that I can find every computer problem I ever have in a thread somewhere where someone else had the same problem too....but the threads never have solutions. There should be a name for this phenomenon.

Please don't double post. Look at your other thread.
If you want to get rid of Windows and the BC partition use the Boot Camp assistant program to remove the Win/BC partition. Don't do it manually with Disk Utility Use the BC A program.

Can no longer see Boot Camp Partition

Hello all,
I was having problems with booting into Boot Camp/Windows 7 (I was just getting a black screen), so I attempted to delete the boot camp partition and reinstall it. When I did that, the program hung for a while, and finally said there was an error deleting the partition. However, it appears it like halfway deleted it, as it no longer shows up! When I go into disk utility, Macintosh HD shows blue, and then there is a 50 GB partition (the size of my bootcamp) that is white, but it is unlabeled. I cannot adjust the partition to make it the whole HD, and if I go to boot camp assistant, and try to make a new bootcamp partition, it bounces back with an error message as well. I am wondering how I can restore the partition back to the original all mac hd partition..ANy help would be greatly appreciated!!

WinClone 3 $20
When you move to a new OS: clone your system, make sure you have backups you can use - for each - the partition table "rules" change with each new OS. And you want to reformat a drive from time to time especially then.
Carbon Copy Cloner 3.4 is a good way to clone your OS X partitions.
Basically, "start over" and restore to one HFS volume with OS X then run Boot Camp Assistant, then restore with Winclone image you made easier.

Can you create a boot Camp partition on a Fusion Disk?

Can I install a BootCamp partition on a fusion disc?
Can I install a BootCamp partition (Wndows 7) on a 1 TB on which OSX mac Yosemite or Mavericks has been installed first? I have a 2012 MacBook Pro, that already has a 400 GB Boot Camp partition, but I am considering replacing it with a fusion disc or an SSD since I shall have to install a windows compatible medical dictation application that could use a speedier disc. Will Mac OS and Windows interfere with each other on the SSDpart of a large fusion disc ( 1 TB) if I switch back and forth from rebooting on Mac OS , then on Windows and vice-versa? Does the SSD part of the fusion disc get confused, and will the fusion disc tolerate the installation pf a Boot Camp partition in the first place, or just give a stretch of plain 5400 RPM disc without the SSD part ?Can I

1. On single-disk Macs, you can use an SSHD (as a single physical disk), but not an SSD/HDD. There is a no single physical unit which is a Fusion drive. A Fusion drive consists of a physical SSD and a physical HDD. MBPs on which the Optibay has an SSD/HDD and main bay with SSD/HDD will support a Fusion (aka CoreStorage volume). Yosemite supports a Fusion drive, which has an internal SSD and and external HDD (the reverse makes no sense, but is possible).
2. On newer Macs, with 1TB PCIe flash, you have an SSD as your whole drive.
3. The two environments, OS X and Windows are self-contained, on separate partitions. The underlying hardware is common.
4. On a Mini, which supports two drives, I have a 256g SSD/1TB HDD, in a DIY Fusion drive, with Windows on the SSD part. Bootcamp Assistant does not support this, but third-party tools can be used. The other option is to install OS X and Windows on a SSD, and later add an HDD and include into a CS volume. This is what I would recommend for you.
5. The 13-in 2012 MBP will allow you use a USB installer, without the need for an Optical drive, so it is possible to replace the Optibay with an HDD, create a Fusion drive. If BCA is used, it will put Windows on the HDD on this specific machine if the Fusion drive is created first.

How can I get my Boot Camp partition off my old drive?

I swapped out the stock 160gb drive that came in my MacBook Pro since it was acting up. I installed a new drive and restored it with Time Machine, but now my Boot Camp partition is still on my old drive. I slipped my old drive into a usb sata enclosure and tried booting from it in hope I could back it up with Winclone. When I went into the startup disk selector the drive would not show up (but it sounded like it was trying to spin up). Earlier when I pulled the drive out of my MacBook Pro it was still functioning fine, so I do not think the drive has failed.
Any ideas on how I can get the Boot Camp partition off the old drive? Thanks for your help.
-Ryan

Some drives require more current to spin-up from a "cold start" than most USB ports put out, even if the port supplies. Additionally, if the drive is failing, it may require even more power for the startup.
I have a couple USB enclosures with external AC power that I keep around in case I run into drives like this. Failing that, I also have a couple of USB cables which use 2 ports to provide additional current. Also the cable length, and gauge makes a difference.

Can VirtualBox use a Boot Camp partition for a virtual machine?

Parallels can now run your boot camp partition!

Having seen this question many times in this forum, I thought I'd let people know that the new beta of parallels can boot from your existing boot camp partition. It also has a few other features with some major cool factor. Check it out here.

unforunately it won't work if your bootcamp partition is fat32, however they said it will be fixed in the next release!

Windows 7 will only install on an NTFS Formatted disk: boot camp partition not formatted right?

I recently tried to install windows 7 on my Macbook (early 2008 white). Boot camp made the partition and I even got to the Windows install screen, but the partition made by boot camp could not be used to install windows on, because it was in the wrong format, evidently (Error: windows can only be installed on a NTFS disk, or something like that). I tried to find someway to reformat the partition in disk utility, but I don't see anything that could change the format. Please help! (If there isn't a way to fix this, is there at least a way to delete the partition? It's rather annoying having 100 gbs of your harddrive just siting there, unable to be used)
And just a side question, does it matter whether you install Windows 64 bit or 32 bit? The printed-out boot camp guide said only the 32-bit version, but it didn't include anything about Windows 7)
Thank you!

Hi,
Windows 7 needs its system to be installed on a NTFS formatted partition.
There 's no way to use FAT32 as file system for this.
Pages 8 - 10 of the BootCamp Install Guide http://www.apple.com/support/bootcamp/ describe how-to reformat the partition to NTFS during the Windows installation.
Officially 64-bit Windows 7 is not supported on a 2008 MacBook.
However, there are instructions to be found on how-to do it nonetheless.

How small can I make the boot camp partition on my MacBookPro internal drive?

it seems that in order to get Windows7 on to my old non supported MacPro 1.1 that I need to firist install onto this mid 2009 MacBook Pro I want to do the install onto an external firwire800 hard drive which I have formater and Downloaded and installed the Windows support folder using the boot camp installer but the installer wants to grab 20 gig of my internal drive for the win 7 install what is the minimun that I must have on the internal drive to install and use win 7 on the external drive?
is ther annother way to get Win7 onto my MacPro1.1 where it can live on an internal drive of its own. I do not have have it running on this MBP5.3 other than to get it running (64 mode) on the old tower In addition to the MBP I have at hand the esternal drive a blank 16 gig thumb drive and a firewire800 external DVD drive that I use mostly as a burner on the macpro as it is faster than the internal superdrive that it came with

I assume that is a product so then I can remove the bootcamp partition from my internal drive and boot to the firewire 800 drive or do I need to have a SSD drive inside the macbookpro first?

Please, I'm french, so if you could answer me in french, it will be easiest for me !!!
Thanks,

While we all have MacBooks in this forum not all of us use BootCamp. There's a BootCamp Support Community where everybody uses BootCamp. You should also post this question there to increase your chances of getting an answer.

Snow Leopard and Boot Camp partition

hello all.
can i keep my Boot Camp partition intact when performing a clean install of SL?
does it allow me to format only the Mac partition of the HD, keeping the Windows (Boot Camp) partition untouched and fully functional?

I would move to SL if, and only if, I had an external drive with a bootable clone of my internal on it and had my files backed up separately on a second partition of the external. I think that there is enough risk in going to SL that such conservatism is warranted. I would not use time machine. Without getting into detail, it can be highly problematic. You will be able to extract your settings, files, and programs from your clone if you do the current version of an erase and install.
To erase and install, start up to your DVD and stop after selecting your language. Use the menus to start Disk Utility and erase you drive. Quit Disk Utility and proceed with your installation. At the end, you will be able to choose to reclaim your settings, files, and apps from the clone (leave the external drive plugged in during the installation).
If you do not like SL, then you can restore your internal using the clone. I would do all cloning and related restoration with SuperDuper. This app is up to date.

Any way to reduce the size of Boot Camp partition?

I made my Boot Camp partition way big and now I'd like to smallify it by about half, down to 60G or so (it's 130G now). Is there any EASY way to do this?
Many thanks,
Pier

In Vista (Ultimate in my case), RightClick My Computer -> Manage: select Disk Management. In Vista you can shrink your (C:) Boot Camp partition which leaves OS intact but allows another install to new (D:) (extended) volume created within space. In XP, I think same can be done with Diskpart.exe which is in \System32. As I have, you can install another Windows OS to the new partition.
I can't see data from Leopard OS for the extension made, though I can see Ntfs files and copy/paste from original Windows (C:) volume bootcamp set up. I do not know if formatting the new split to Fat 32 would make it a share space for Leopard.
