Hey everyone, and thanks to a particular person who helped me on my last thread!
I'm wondering if a mac can boot from a DVD if only the installation file is there (nothing else). Can a iMac boot from a .dmg installation file (if you hold down c on start up)? Thanks.
Also is a .toast extension a bootable file on the mac?
 
A .dmg file is only an image (Disk iMaGe to be exact) of a disk (CD, DVD, HDD, ...) or an accumulation of files being put into a .dmg file.

If you burn the .dmg file to a CD/DVD, you are just copying the .dmg file to another medium. There will not be any boot ability.

To boot from a DVD you have to use Disk Utility and burn the .dmg file that way.

Open Disk Utility, in the Utilities folder (/Applications/Utilities).

If the disk image you want to use doesn't appear in the list, drag its icon to the Disk Utility window.

Select the disk image and click Burn.

Insert a blank CD or DVD into your computer's optical drive and follow the onscreen prompts.

And what if your mac is unable to start up? How would you then run that .dmg/.toast file?

You need to burn that file to a CD or DVD, because a Mac (without the proper Mac OS X) can't boot just from that file (.dmg/.toast).

Do you have access to another Mac (school, friend, family, work, neighbours)? If so, burn that .dmg file there via Disk Utility or the .toast file via Toast Titanium if available.
 
No, unfortunately I do not have another mac anywhere. Most of my friends use windows.
Would it be possible to somehow make that .toast file bootable using windows XP?
 
I don't know.

How to burn .toast files onto DVDs using windows XP

Thank you for your help.
is it possible to just simply rename the extension? Or would that corrupt the file?
I also only have one more burnable DVD disc so this one has to work :(
I looked for .toast to .iso converters but all that came up were .dmg converters
Does anyone know of .toast to .iso converters programs for windows XP? If I can convert it to .iso, I'll be able to burn the file. Thanks.
 
Renaming .toast files into .iso files seem possible.

I just did a quick test.

Opened Toast, dragged some files into that, saved an image as .toast file.

Renamed the MyDisc.toast to MyDisc.iso.

Opened Windows, copied the file over there, installed MagicISO and mounted the MyDisc.iso file without a problem, could even see it in Windows Explorer and accessed the files on the "disk".

To burn .iso files you can use this: http://fileforum.betanews.com/detail/ImgBurn/1128426215/1
 
Thankyou! I will find out how to burn the program using Nero. But won't Nero only burn the .iso file, not being bootable on the mac?
 
Thank you. I will use Nero and if there are more questions related to this thread I'll post here.
 
Sorry, I'm using ImgBurn right now and there are these two options. One is "Write Image file to disc" and the other is "Create Image file from Disc" Which one do I pick? I'm trying to make this .iso into a bootable DVD disc for the mac. Thanks and sorry for such a newbish question :D
 
Going out on a limb but I suppose write image to disc is the one you want. Create image from disc is for copying a disc which already has info on it.
