Boot camp partition?

You need to first format that partition NTFS before you can install it. This is done within the Windows installer's formatting window.

Click on the "Advanced" button and format your Boot Camp partition.

Read and follow the Boot Camp Installation Guide http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.7.pdf

click on advanced option

you didn't read the BCA instructions or guide, page 22.

If everyone who posted that same question (yes, daily!) would read or seach or just look at the screen and the options right there... it would avoid all this.

The original beta of Boot Camp Assistant did format as NTFS for users when the partiton was 32GB or larger (40GB or larger recommend for Windows 7) but due to Microsoft holding rights to NTFS I guess and Apple wouldn't even provide the feature.

I have the same problema, I am trying to install windows 8 and until now with no sucess. The instalation by the bootcamp runs smoothly, but when I boot from the USB, start the instalation process on windows and it asks me what partition I want to install the windows, I try to choose the Partition 4: BOOTCAMP and it doesn't work, even after I try to format as you said...And if I don't press the Alt button, when the bootcamp finishes the instalation and reboot the mac, it goes to a black screen where said that I don't have any boot devices connected

Why do you have 4 partitions? What are they? Bootcamp can only be used on a drive with an existing single partition plus recovery parftition. What partition options are you given?

You should really start your own thread. You are asking in a year old solved thread. Many will not even read your question because the thread is already solved.

Thanks btw.

I have only 1 partition, but when I create a partition for Windows, boot camp creates partition1 with 200mb, partition 2 stay with the 650GB (Macintosh HD), partition 3 has 650mb, and partition 4:BOOTCAMP in my case I define to 100GB.

I will create my own thread, thanks for the advise

The 2 small partitions are for recovery (Windows and Mac) you have 2 active partitions, OSX and BootCamp.

I know, the problem is when I try to install Windows on partition4:BOOTCAMP it says it needs to be formated because it has to be a ntfs format. Then I format and It says this error.

It's because I try to install Windows with a USB Drive in a Mac that has SuperDrive?

Yes, it very well could be, is anything other than the USB with the Windows iSO plugged into the USB ports?

No, I only have the USB with the ISO plugged.

It seems to be the only solution, I will make a boot dvd with the .iso and I wil try. In ohter thread someone alert to the same thing, so it could be. After all I have to change the info.plist of the assistant boot camp so I can install the Windows from the USB, because initial it didn't have that option...

I agree.
