I got problem when try to create 4 partition used Disk Utility, I installed Macosx 1st then win7, all processes go smoothly
1st Partition for MacOSX: 50GB
2nd for Windows : 100GB
3rd for Data1 : 300GB
4th for Data2: 400GB
Everything went as expected except one: Charmeleon/MacOsx created 2 partition 200MB and 125MB, In Windows, it auto detected 4 partition:
Windows. Data1 and other two. I couldn't see Data 2 partition, THen I went to DIsk Management to format Data2, but then all my Partition is visible include 200/125MB and after that I cannot boot to Mountain Lion anyomre.
How can I avoid that happens, and how can I manage to help my Data 2 partition?
Windows can only see the first 4 partitions (including the EFI partition that doesn't show up in disk utility that disk utility creates by default when formatting the drive.
Suggestion: if you want Win7 to see both Data 1 and Data 2 partitions, format the drive as follows
partition 1 format it for Win7 MSDOS FAT
partition 2 format it however you want, name it Data 1
partition 3 format it however you want, name it Data 2
partition 4 format it Mac OS Extended, Journaled for OS X.
Install Windows on the first partition, reformatting to NTFS with the Win7 installer. update it, install your security suite.
Then install OS X on the 4th partition. update it, run multiBeast to install bootloader, audio and networking, install your apps.
Now either OS can see the Data partitions. If you do a diskutil list in terminal you should see 5 partitions. In windows, you will see 4 partitions and some unallocated space (your OS X partition)
drive 1 partition 1 type EFI should be about 200Mb
drive 1 partition 2 type Fdisk whatever your Win7 partition was sized
drive 1 partition 3 type ? whatever you formatted the Data 1
drive 1 partition 4 type ? whatever you formatted the Data 2
drive 1 partition 5 type GPT OS X
