Bootcamp getting stuck at Windows Setup

Thanks for your help Kappy.

I formatted the only partition that matched the size of the BC partition I made. Here is a screen shot of the set up screen on my MacBook pro., with the error below when I tried to install windows into partition 4. I suspicious about partition 1, which is labeled as a system partition, and is full. It seem this is what set up is complaining about in the error description, which says the SYSTEM partition (partition 1?) doesn't have enough free space.

I forgot to open the caches folder which is filling the EFI. Now I can see this volume is full. Can these files be deleted so there is more room for Windows to stop complaining about this volume not having enough space ?

FIXED

Hi, I did run diskutil repair disk, and it said it added some windows file (I think because of the BC partition), but when I mounted the EFI, it was still full (only 2MB free space) I went ahead and deleted the cache folder, which freed up 170MB in the EFI partition, crossed my fingers the mac would still boot up, and it did. Then I went through the BC Windows set up and had no problem getting Windows to install after formatting the BC partition. The problem was there was no room on the EFI for certain windows system files that need to be installed there.

Yes, I have NTSF formatted the BC partition I created with the BC Assistant.

The problem is after that step. Windows give an error and won't install on that formatted partition, as I explained above.

Does anybody have experience with this problem?

thanks,

Im installing BC on my MacBook pro internal SSD ( It should work, ive done it before). I follow all the regular steps to set up the USB installer using BC Assistant. With the USB installer, the mac boots into Windows setup, and I format the BC partition in windows set up. THEN, I get this error: "Set up was unable to use the existing partition because the system volume doesn't contain the required free space", and windows does not install on the BC partition.

This is the reason Im asking questions about the EFI, partition, as this windows error suggests there is not enough free space in the EFI SYSTEM partition to allow Windows to install. On the web there was an article about reformatting the EFI SYSTEM partition to solve this problem, and allow windows to install on the NTSF partition you allocate with the BC Assistant.

thanks

Right!

So Windows does need to put some stuff in that EFI partition, and in my case its stuffed full with no room to spare. I recently did a clean install of the OS, but formatted the OS partition not the entire drive (I think this was a mistake) so that may explain the "clutter" in my EFI.

The question now: can I delete the contents of the EFI? I read that the OS will repopulate whatever it needs in there,, but Im not sure. Does anybody know what happens if you clear the EFI? Will it prevent to mac from booting up?

No Windows stuff here, and the total is less than 25MB in this EFI. Then what is the EFI that is showing up in the windows set up screen shot(partition 1) that is 200MB ? Hmmmm.
