Installing OSX from USB Flash - HOWTO

Postby gruffy » Thu Jan 01, 2009 1:51 pm

Hi there!

First...let me thank all here. Been reading a while and not contributing that much. Here is a first attempt to contribute a little.

This is a small HOWTO-guide for how to use a USB Flash memory to install OS X onto the AA1. This is very useful if you do not have an external DVD player for use on the AA1.

There are several steps you need to execute, and keep extreme caution to the ordering of the steps to fully make this work.

All in all what you do is:
- Create a MBR on the USB drive
- Copy the ISO to the USB drive
- Change the "ID" of the USB drive-partition to "AF"


Step 1:
Make sure you have all that is needed..
- One Vista (or possibly XP) computer...but I have only tested on Vista.
- One ISO of OSX, in my case iAtkos v5i
- USB Flash drive LARGER than the intended OSX-ISO you are using. In my case a 4GB is enough for iAtkos v5i.
- Download the "Leopard hd install helper v0.3". Google is your friend here...
- Download "unetbootin-windows-282.exe"...google is your best pal yet again...

Step 2:
Format your USB Flash to FAT32 in Vista. I.e. right-click and format.

Step 3:
Start unetbootin and select "Distribution" to "FreeDOS", version "1.0". Make sure to select your newly formated flash drive, in my case "G:". Hit "OK" to have unetbootin do its thing.
This step is purely done to have a "Mater Boot Record" to be written on your USB drive...

Step 4:
Using Vista explorer, delete all files from your drive, in my case "G:". Doing this will remove the "FreeDOS", but keeping the MBR...which is what we want.

Step 5:
Use the "ddmac.exe" in the "Leopard hd install helper v0.3" tool to "copy all iso stuff" to the new drive. This tool is not in english an a little buggy...but keep "clicking & selecting" until you get the "Start" button to be enabled and you have the correct disk selected.

The following text is taken from an MSI Wind blog (http://blog.binaryfactory.ca/2008/12/installing-os-x-on-the-msi-wind-u90x-without-another-mac-from-a-usb-stick/):
In the first field, browse to your previously downloaded OS X Iso.

Select the USB drive as the destination. You will get a warning about the driver, ignore it.

In my case, I unchecked boot.ini – you would leave it if you were running the tool directly on the Wind to install from another partition.

Leave the other checkboxes checked, then click Start (the only button).

Sometimes, start is grayed out. Browse to the ISO, check and uncheck a bunch of stuff and it usually becomes available. Browsing to the ISO, unchecking the “write” box (between the destination pull-down menu and the start button’), choosing the destination and checking Write again seems to be a good combination most of the time.

Once you click start, it will take around 10 minutes, and the progress bar isn’t a big help. It helps if your USB Stick has a LED, because the app does not take much CPU and you could think it has died. Be patient, grab a cup of coffee..


Step 6:
When the ddmac.exe has done its thing...now start a command prompt from Vista and start the "diskpart.exe":
- Execute a "list disk" to find your USB drive, then select it with "select disk 2" where "2" was my USB drive...make sure this is correct for your case!
- Then do a "select partition 1" to select the first (and only!) partition on this disk.
- Then do the magic stuff: "set id=af" to make it have correct ID (else it will not work...)
Exit "diskpart" with an "exit".

Step 7:
No insert your USB into your AA1 and reboot it, make sure to hit "F12" at boot and have it boot from your USB...install OS X...but this is another story!

Have fun and hope it works for you as well!

Thanks for the tips!

Would this be suitable for a 4gb iPod? Its the only drive I have suitable sadly...

But I have the bad feeling that due to the iPod's firmware and the way it autocreates files will mean its not going to work. I'll give it a try a bit later, but does anyone know anything about this?

Thanks

Hrm...might be tricky to do this on an iPod as you are messing with the drive in pretty low level things. My guess is that it will not work (only guess however...) and I would personally not dare the test... ;-)

i figured out how to make it so that the greybox always show

first format the flash drive

second open ddmac do not run it

third run unetboot thing

fourth run ddmac a.k.a hit start

Code: Select all
the reason i think this works is because the program is written in vb, i think,  and there is nothing checking the flash drive in real time aka a timer to check. BAD CODING, but works out good here :D

I can't seem to make this work out. I'm trying with the kalyway disc with a 4gb usb memory. Space is not a problem i think, but the main issue is that de ddmac just won't transfer the image to the usb. I know this is a little vague, but have you got any ideas why this is not working? I do the unetbootin thing and it just says: disk not empty, try another!

Hi there! Have you executed "Step 4", the whole point with this is to remove all files from the disk after unetbootin has installed the MBR + some files. We just need (and want) the MBR to stay...the rest of the files should be removed before trying the ddmac tool. Please check this first.

Yes i have! That's the weird thing :s I saw something in a post that you have to disable something in the drive properties, but i can't remember where it was. I installed xp and was able to move the image into a partition, but every time i finish installing the os it doesn't boot. The first time i did it, it said something like: os cant load. now it prompts me with a realtek driver and something pxe :s i really can't remember what it said. I'll keep trying with the usb method untill i get it, to format the whole disk and only have the mac partition. if i can't do it with that, i'll shot myself... haha just kidding, i'll install xp again :s

Hi there! Keep trying m8! Never give up! ;-) Hrm...just a question for you here, are you actually getting things to work such that you can actually start an installation from the USB disk? From your last post it seems like you got it to install on the One, but then booting this failed? I saw you were testing with Kalyway, and I am not experienced with that at all...just tested iAktos v5i, maybe that will work better? (It should work with kalyway, but as I have not tested it I don't know.)

Another thing, maybe you should make sure that the "boot-ini" is un-checked when running ddmac.exe? Is this the property you are thinking of?

a) select source ISO
b) UNCHECK the "Write" box
c) as target partition, select the USB stick drive letter (ignore the "not hard disk driver, try another" message)
d) CHECK the "Write" box again
e) Start button should now be active. Click it and everything should work fine.


This is from an user from http://forums.msiwind.net/post60464.html#p60464 This worked for me.

Also, you don't need unetbootin. Just format it with FAT32 and follow the steps that I just quoted.

Great feedback! Thanks!

I will change/update the HOWTO soon with new stuff about no unetbootin! Am at work now...so some other time ;-)
