Does the required size of the Win 7 (64-bit) Ultimate partition change when one uses it on an I-Mac with Boot Camp? I am trying to use it on an I-Mac 27 inch (late 2012) with the following data:

  • CPU = 3.4 GHz INTEL CORE i7
  • RAM = 32 GB
  • HD = 3 TB total, 1.5 TB used.
  • OS = OS X 10.8.3 (Mountain Lion)
  • PARTITION MAP TYPE = GPT (GUID Partition Table).

Boot Camp initially gave a default amount of 20 GB but when I used that amount and then tried to use a DVD copy software which required about 4.2 GB for a temp file, Windows said all I had left was 2.7 GB (i.e not enough to use this program). Is there a "sane" partition amount to use in this situation? I will have to remove the Win 7 partition & create a new one & re-install Win 7. I'm trying to do the "right thing" now to avoid having to go thru this again.

The partition size requirements for Windows does not change. Why are you creating such a small partition for Windows? – Ramhound Apr 18 '13 at 17:31
Keep in mind that the minimum size requirements for OSes are just that: minimums. When you use real-world programs, they impose their own requirements. A DVD-copying program is likely to require several gigabytes, as you've found, thus chewing into whatever small amount of free space you may have had after the initial OS installation. None of this is any different when running Windows on a Mac vs. when running it on a generic PC. – Rod Smith Apr 18 '13 at 17:43
