How are you guys installing 64bit Windows on your Mac? On my previous MBP, I installed 32bit Vista without any issues. Now I want to put Windows 7 on my MBP (sig). I was surprised to see no Window Install Guides here at MR. I currently own Windows Vista Ultimate and my desire is to put 64bit Windows 7 on my computer. Thinking I could first install Vista and then use an upgrade copy of 7, I started with the Bootcamp process by creating a partition. However when I used a 64 bit version of Vista, none of the partitions that appeared in the Windows installer were compatible. I got a message about not NTFS (Windows format) when selecting Partition 3 Bootcamp, the partition I'm pretty sure that the Windows install should go. I also noticed in the Bootcamp install instructions that that it specifically states that only a complete Windows 7 install will work, not an upgrade version of W7. This brought up one of many questions. 1.The instructions saying that you can't use an upgrade version only of 7, but what if you have a Vista install all ready, then would an upgrade version work? 2. Does the latest version of Bootcamp v3 work with only Windows7 (versus Vista or XP)? 3. The Bootcamp instructions don't differentiate between 32 and 64 bit just say Windows 7. Can it be inferred it is your choice? 4. Any compelling reason to pick 64 bit over 32 bit? 5. Would it be better to have a version with both 32 and 64bit versions or just stick with one or the other? 6. Is Bootcamp compatible with a 64 bit W7 install without any special procedures? 7. Does Bootcamp format the partition in NTFS or is it the Windows installer? 8. Any version of W7 to specifically avoid? 9. Any good related links? Any other tidbits would be appreciated. Thanks.
