I know i have not posted in awhile, but here is the start of a new day! And here are instructions for Dual Booting Snow Leopard and Windows 7 on a MSI WIND U100. I haven’t tested this yet, but will update tonight after I have. I cannot post a link to the actual ISO… but it can be found. Full Credit to:

Things I used:
1
plug in the osx usb key and turn on the mini. Press f12 to boot from usb, and wait until the mac installer starts.
2. In the utilities menu open disk utility. Select the hard drive (not the existing partitions but the hard drive itself), and click on the partition tab.
b) If you are doing a fresh install, you want a GUID partition table with 2 partitions. The first needs to be in the hfs+ format – this is your mac partition. it can be any size you like as long as there’s enough for OSX – typically you need at least 10gb. I chose 110gb). The second partition (for windows) needs to be in the FAT format and again can be any size you like above around 10gb – I chose 50. Note: When you name the FAT partition make sure the name is not longer than 8 or so characters. I used ‘windows’ as the name – you can change it later….
3. Quit disk utility and continue the mac installation
1. First of course you need to burn the iso. It will fit on a single layer dvd.
2. Put in the disk and power on, then tap F11 to get to the boot menu. Choose the SnowyWindoSX Alpha.iso. It does take about 4-5 minutes to boot the disk, don’t worry, that is not the case with the final install.
3. Once booted up, choose the language, click continue, and agree on the licence.
4. Click on Utilities on the menubar, and click Disk Utility. Create and/or format your partition as Mac OS Journaled. It can be MBR OR GUID.
5. Close Disk Utility and choose your partition.
6. Click Continue. Do NOT click customize. It is pointless. There is nothing on the list to customize.
7. When you get to the Install button it will check the disk, you can skip it or not.
8. After it is finished, Reboot back into the disk, choose your language, and then click Utilities on the menubar and click Terminal.
9. In terminal, type:
cd /Volumes/MacOSXInstall/fix
diskutil list (This will give you the disk and partition number for your Mac install)
fdisk -f boot0 -u -y /dev/rdiskX
dd if=boot1h of=/dev/rdiskXsY
fdisk -e /dev/diskX
p
f Y
w
y
q
(X=disk number from diskutil list)
(Y= partition number from diskutil list)
In the following image, the Green text is the name of the partition youinstalled to, the red text is the disk number, or X, and the blue text is thepartition number, or Y.

10. Now reboot and boot into your newly installed Mac. Note that sound and graphics won’t be working at this point.
11. Once booted into your fresh install, mount SnowyWindOSX Alpha on your desktop. Look in the Optional Installs folder for the 10.6.1 update. Install it, but DO NOT REBOOT.
12. In the Optional Installs folder there is a package called Update Handler. Install that package. Then stored that package on your hard drive. It will handle future updates in this same manner.
13. Now you can reboot into your perfect system.
14. If at this point you do not have full graphics, look in the Optional Installs folder. Read the Read Me file. It will explain the use of EVERYTHING in the folder.
NOTE: The Update Handler.pkg will throw errors about the kexts, but don’t worry, they are false errors. The package rebuilds the kext cache when it is finished, which fixes the errors.

1. For internal mic just double click on the VoodooHDA prefpane to install it. It will take some time to find the perfect settings for you.
2. For those using the nettop, copy nettop.sh to the desktop, then open terminal and type:
sudo -s
cd ~/Desktop
./nettop.sh
3. If you prefer the Voodoo trackpad drivers, copy the Trackpad folder to the desktop. Then open terminal and type:
sudo -s
cd ~/Desktop/Trackpad
./voodoo.sh
4. if you don’t have 1024×600 graphics after install, copy the DisplayProductID-717 file into /System/Library/Displays/Overrides/DisplayVendorID-756e6b6e and replace the one that is there.
5. If you have the realtek/ralink wifi card, install the drivers for it that are in the Wireless Drivers folder.
6. If you need Rosetta, you can install the pack from here.
7. The 10.6.1 update is included, just install it and see number 8.
8. On major updates, such as 10.6.1, you need to install the update, but DO NOT REBOOT! Then install the Update Handler.pkg in this folder. Then reboot. Keep the Update Handler.pkg for future updates.
4. Once the installation is complete it will prompt you to restart. Do not restart into OSX – turn it off when it is about to cycle, and put in your windows stick. boot into the 7 installation environment.
5. Select language and click install. You should get to a disk utility window. Select partition 3 (the windows FAT partition that you created), and click format (it will format the drive in the NTFS format). You should now be able to click next to install windows.
6. Allow windows to install, it’ll ask you a few things and restart a number of times. Once it’s finished your computer will boot automatically to windows as if it’s the only OS installed. To change the active boot back to Mac OSX do the following: Boot again from the windows installer. You need to set the mac install with the chameleon bootloader as your active disk – when it’s loaded up press Shift+fn+f10 and bring up the command prompt. Type the following:
Diskpart [enter] (you may have to wait a little for this to load)
Select disk 0 [enter]
Select partition 1 [enter]
Active [enter]
Now reboot, and you should be greeted with the chameleon bootloader, and be able to choose between your mac install and a perfectly working windows 7!!
If at any time you need to run NBI again on the OSX install (for example upgrading from NBI 0.8.3RC2 to RC3), follow these steps:
7. Boot into OSX and run Netbookinstaller. Make sure you have the chameleon bootloader and generate dsdt file boxes checked, and that quiet boot is disabled. Click install. Once the install is finished, OSX will now be the active boot, But your windows boot sector will be corrupted.
8. To correct this, reboot, insert your windows usb key and boot from it. If you tried to repair the boot sector now, the windows installer would not succeed, because it is looking at the active partition’s boot sector (where it assumes the windows install is) but this is in fact the Mac EFI partition. To get it to fix the windows boot sector we need to set the windows partition as active: When you get to the language choice, press Shift+fn+f10 to bring up the command prompt. Type the following:
Diskpart [enter]
Select disk 0 [enter]
Select partition 3 [enter]
Active [enter]
It should tell you that partition 3 is now active.
9. Close cmd prompt and click repair windows install. It should now find the windows install and repair the boot sector (and not mess up your chameleon install).
10. Finally, when it restarts, boot to the windows installer one last time. You need to set the active disk to your mac install with the chameleon bootloader – Press Shift+fn+f10 and bring up the command prompt. Type the following:
Diskpart [enter]
Select disk 0 [enter]
Select partition 1 [enter]
Active [enter]
For those who didn’t read the Read Me. file, I have posted the Read Me here.
