I have partitioned my Mac and have Lion OS & Bootcamp with Windows 7,

Now, I want to create a new drive for data. However, as I read items on the web on using the Mac Disk Utility, suggest that it will destroy the existing partitions.

I believe I should be able to use the Mac Disk Utility and scale the Mac partition down and the remainder will be the new data partition. With the Bootcamp partition remaining the same size as before starting.

thanks

That is my understanding as well. As always, do a fresh Time Machine backup first just to cover your bases.

I wonder if you need to boot from another start disk first though. Just a thought.

I was hoping someone here would have had a more definitive answer that they have done many times and not a problem.

I had partitioned for installing bootcamp without issue and I know in Windows I have done it many times without issue.

Still working on a solution to use Time Machine and Truecrypt.

Seriously. It will work. AND make sure you have a good backup. There are never any guarantees with data.

Thanks for the feedback. I was holding back on commenting until I had a chance to progress.

I want to put this on hold while I sort out some other system issues. Unfortunately the only I can see is to put comments every now and then.

Finally got around to partition the drive into three (Mac, WIndows, data). Everything from the Mac side looks good. Mac is running, I can see the new data drive and the Bootcamp - Windows drive.

Even pulled a few files from the Windows onto the new drive without issue.

Rebooted to enter into the Windows 7 from Bootcamp and get a message on a black screen that the boot is not recognised and to enter a valid disk.

Rebooting and holding down ALT I rebooted into Mac without issue.

I can again see the Windows partition and wonder around in the drive.

How can I fix the booting into Windows Bootcamp issue?

Thanks
Peter

Hate to be Mr. RTFM, but are you working from these instructions?

Did debate on new or continue with this question. As the issue occurred from asking this question.. But, ok will close and open a new question.

As for the Mr comment. I have referred to it, and had another look at it from the Mr comment, but cannot see anything telling me that if you want to now create a third partition, what you need to do.

Even though I was able to partition my hard disk into three and I can still see the Bootcamp Windows partition, Windows will not boot.
