can i downgrade bootcamp from 4.0 to 3.0

If its a new mac that came with lion than the answer is NO otherwise if its a snow leopard mac, you could just revert back to snow leopard and use bootcamp 3.0
 
Or stay with Lion and use Boot Camp 4.0 to partition the HDD and use the 3.x drivers from a SL disc.

The key is that for most 2011 Macs Apple does not officially support anything earlier than W7 under any version of Boot Camp.

Please be very specific about what you have done in the past and what your current configuration is, etc...

This particular error will not be fixed by reverting to 3.x

i tried to pull the boot camp off the external and it comes up with this The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.

You are not explaining yourself well.

What do you mean by "pull the Boot Camp off the external"? The Boot Camp app? A copy of the partition? The drivers? ...

How did Boot Camp end up on the external?

Step by step how did you get here and where do you want to get to.

I think he has the same problem as me..

Under SL I had a Windows XP Bootcamp Partition... everything was great. I have since upgraded to Lion, and I can no longer boot Windows XP. I want to downgrade Bootcamp 3.0 so I can use my XP install.. because I'm sure not buying Winblows 7 for the once a month I boot it up to test webpages.

Does the Lion upgrade update the boot loader? It must... because XP booted just fine the day before I upgraded to Lion. I understand that you can't create XP compatible partitions from Lion, but shouldn't my old partition (created under SL) still work?

I'd appreciate any thoughts on how to get my XP install booting again.

Cheers,

You we might be able to figure out. You don't have a mystery external drive do you? :p

Can you run rEFIt's partition display tool? Download from here https://forums.macrumors.com/posts/11629332/ launch Terminal.app and run:

Code: 
sudo ~/bin/showpart /dev/disk0

post the output in a CODE block here...

My guess is it has something to do with the recovery partition creation.

On my MBP things worked just fine with W7 Ultimate 64. I have yet to upgrade the Macbook though.

It could be that with Lion and the recovery partition, the Boot Camp one got moved to the 4th position. On a GUID disk with Tiger through Snow Leopard and Boot Camp there is only a 200 MB EFI partition, the OS X partition, and Boot Camp. With Lion, the Recovery Partition is put before 4th, so now Windows.

At least, that's what I think, I'm not sure 100%.

Oh man, this is exactly what I want to do. My condition is that I have Lion, Windows vista and Windows 7 upgrade. I want to finally get installed win 7 with bootcamp.

Can you please provide me with some instructions?How do I use these drivers? I desperately appeal to you for help, me, a noob. :)

Cheers buddy

- Use bootcamp (under Lion) to prepare the space for windows.
- Install Windows as per instructions
- At the end of the install (after windows installation has finished) you'll have to install the drivers. Basically in Windows you run from the install DVD the bootcamp setup which installs the drivers. However in Snow Leopard this Windows part of bootcamp install was sitting on the OS X install DVD, for Lion you have to download this. (BootCampESD 4.pkg, about 500 Mb) You have then to burn this to a DVD (under OS X) or else (if you do not have a DVD player) put it on a USB stick so you can use it in Windows.
Restart Windows and run setup.exe from this DVD/USB and you are done.

Do I have to download and burn the Lion BootCampESD 4.pkg or use the one (BootCampESD) from SL install DVD? Where could I find that file in any case?

Finally, in which point of the procedure am I doing the upgrade from vista to win7?

Cheers mate!
