Is there a way i can take my snow leopard user DVD, and make a bootable USB out of it on Windows.

My friends mac doesnt have a DVD drive. I already was able to rip it into a DMG file. so how can i take that and make it a bootable USB?

you might want to try a different approach: let your friend partition and format the usb pendrive for guid and hfs+,
then use 'cp -a' under a linux distro in order to copy the dvd-files onto the usb pendrive.

Is there a trick to get it to see your USB drive? Mine won't show up in transmac.
I've managed to open up a image I created from my SD card using macdrive and I was able to edit that image. If I could just get it to see my USB stick i'd be set.

Edit - I figured it out. Had to run as admin.

Guys why don't you give a try on this way!!


incase of making OSX USB Bootable Drive on WINDOWS u need few things u can google it to find ;)

1) 8GB USB drive (atleast or more OR USB HARD)

2) Ultra ISO

3) OSX DVD Installer

4) Windows PC (xp,vista,7) with DVD ROM

And easy to get done in few steps

On Windows PC Format your USB drive in normal FAT32 format

Install Ultra ISO Run it ''As Adminitration'' if on Vista or Win7...put OSX Installer DVD in ROM go

to 'Tools' n select 'Make DVD Image' option...n save it as Standard .ISO file on desire location

Now in Ultra ISO go to 'Bootable' and choose option ''Write Disk Image...''

there you select USB Drive...brows .ISO file....choose Write Method ''USB-HDD+'' and get done in an hour may be less

hope this will help





and if you dont have DVD ROM available but u already have DMG file in system then u simply turn your file extension .DMG to .ISO n follow...

In explorer options, configure to show file extensions, then remove the .dmg extension.

expand ??
why should that be necessary ??
i made all my install stuff with transmac and there is no need for "expanding"!!

transmac is the fastest way to get it done

save the dvd as dmg image and the format the usb drive with that image - thats all
nothing to epand in this workflow

Does that let you make a PC a Hackintosh without a Mac?

u just renames it and that won't work

go to My Computer > Organise > Folder and Search Options > View >..there u check the box Show hidden files and also uncheck the option ''Hide extensions for knows file types''

and now u can change extension DMG to ISO

I've used transmac to format and write Snow Leopard DMG (uncompressed) image to a 16GB corsair memory stick ...all went fine.

However when i try to boot from it on my Dell 630 i get a error on boot "No boot sector on USB device" ..any ideas on how to check if it should be bootable and also make it bootable?

Thanks.

Here's what I'm trying. I'll come back and let you know if it works:

Currently having TransMac make the usb boot stick. But you say it won't be bootable...

well I think we need to use a boot loader no?


Ehhhh. All the guides talk about using osx to make the usb stick.

My plan was to burn the DMG with TransMac (which failed. have 2 dvd's left to try)
and once I had the DVD, to install it on vmware after booting it with the snowy vmware files. (a boot loader for using snow leopard on vmware)...and from there, make a real USB stick from the disk utility, having installed snow leopard on the vmware...

its weird like backwards or recursive or something....kind of process.

but i have not found a way to convert DMG to ISO, which would let me then mount the ISO and see it from vmware to install i think.


Might just have to wait till I can get my friend to come over with his macbook pro someday.

edit: 11/23
haha. I saw this earlier and it helped me figure something out, so I wanted to give thanks to the author and share what I accomplished and how. Then I found out it was Me who wrote it a month and a half ago.

Well it seem to be working. Installed Snow Leopard on VMWare via a guide I found with darwin_snow. Then I use the DVD to restore to a flash drive from Disk Utility. Next step is to follow Tweak's guide here http://www.insanelym...howtopic=189052. Only difference is he is using a real osx install and I am using a vmware install.

Fingers crossed that it will work when I'm done.

Thanks, patnucci - method worked perfectly for me. I had to expand Snow Leopard as well but it wrote on to USB fine. Everything went smoothly although the installation was slower than I expected but I can only put that down to running it off of a USB stick.

I was (re)installing the software on a MacBook that is compatible with OS X. I'm not sure if the same will apply to people trying to install it on hardware designed, originally, for Windows.

Thanks!

I created a topic on using small hard drives as installers (only issue is that it would roadblock portable Hackery; the idea is pretty much desktop-only due to physical-space reasons), as there are still lots of these bigger-than-thumb-drive-but-too-small-for-regular-use hard drives (especially PATA, but some SATA) hard drives sitting on shelves.

sorry for the old topic bump!

I was able to get it working by downloading a trial version of MacDrive for Windows and then going to modify/edit partitions and clicked on my drive. I hit 'initialize disk' and then went back to Transmac and formatted it as HSF+ then reformatted it with the expanded snow leopard image.
