   5. Type: clean //!! Will remove everything on No.0 disk !!
   6. Type: convert gpt
   7. Type: create partition efi size=200 //Win7 only need 100M EFI partition, but Mac need 200M, in this case we used 200M here, you can use 300M or large. REMEMBER DO NOT FORMAT HERE!!
   8. Type: create partition msr size=128 //Win7 NEED, just add
   9. Type: create partition primary size=40960 //40G Win7 install partition, you can change the size, Win7 64 only need 8G for install
