Formatting and Partitioning Hard Drive for Boot Camp and EFI Upgrades

A month or so back, I upgraded the HDD in my Aluminum Macbook to a larger drive. Now, however, I've got a couple of problems caused by me not apparently formatting and partitioning the HDD correctly.

For the Boot Camp Assistant, I get the following message:

For the newest EFI upgrade, I get:

Disk Utility says on my drive:

And that it's already "Format : Mac OS Extended (Journaled)"

So what had gone wrong in the upgrade process that has caused all these headaches now? And could somebody give me a step by step that will allow Boot Camp to be set up and EFI firmware updates to occur so that I apparently don't do something wrong again?

 

make sure to run a permissions repair as well as a disk repair in disk utility, restart, and see if that does the trick. it may not.

and definitely search around, there are a few different things that can cause an issue with bootcamp, but there may be something else wrong if you aren't able to even run the update.

so I would make sure to run the repairs, and do all the normal Mac troubleshooting steps, resetting PRAM etc.

 

I encountered the same issue with my old MBP with bootcamp after deleting the partition a few times.I tried everything in disk utility, short of reformatting. In the end I had to reformat and recreate the guid partition. I think the guid partition gets corrupted some how and needs to be recreated. I think this may your problem also because from what I understand, the computer firmware looks to the guid partition to make sure that it's properly formatted.

 

you partition map scheme is MBR. you need GUID partition scheme to install EFI update.

if this is your startup disk then i believe you need to repartition it from the Mac OS install disk. open disk utility -> partition tab -> option -> GUID
