OS X :: How To Create A Bootable CD/DVD From A DMG
Nov 21, 2008
I am trying to figure out what the best way is to create a bootable DVD frm a DMG file?
Upon first purchasing Leopard 10.5 way back when it came out, I decided to back up the disk on my computer by creating a Disk Image. Turns out it was a good move because now that I need the disc, it seems to have picked up a big scratch on it's surface, and it simply refuses to mount at this point...
I can use either Toast or Disk Utility to accomplish this task (or the terminal if absolutely necessary, but I would really prefer using one of the GUIs I've just mentioned). I was hoping someone would be gracious enough to provide me with instructions on what would be the best way to create a bootable DVD from this DMG file.

I created a bootable usb drive on a windows pc using windows 7 to install windows 8 preview and want to make a copy to install in virtualbox on my imac and burn to a dvd that will work on pc.
I've tried using disk utility to create an image and get a file ESD-USB.dmg, but virtualbox won't boot a dmg file.
I tried converting it in the terminal with:
hdiutil convert -format UDRO -o windows8.iso ESD-USB.dmg
but the resulting file was windows8.iso.dmg. I changed the name to windows8.iso, but even so, virtualbox complains it's unbootable.
I tried the terminal command:
dd if=/dev/disk4 of=windows8.iso
but virtualbox complained that it's not bootable.
I tried the terminal command:
cat /dev/disk4 > windows8.iso
but virtualbox complained that it's not bootable.
Info:
iMac, Mac OS X (10.7.4)

I purchased an app online, and seeing as they had an option to download the app, I downloaded it. (I do believe I still have available to me the option of the cd to be shipped, but I'm not sure) Now I need to use it in a way that requires it to be booted off a cd... The software downloaded was in a disk image format. Are there any specific instructions/steps I need to take in order to ensure that I produce a bootable cd? I'd hate to waste a perfectly good CD-R by a stupid mistake of making it non-bootable.

I'm trying to fix a frozen chkdsk on an imac. It can't see the keboard yet so you can't stop the chkdsk. Next step is to try to boot into dos to fix some things.
Anyone know how to create a msdos bootable cd [that an imac can read]? I can create the cd in a working windows environment. I have found many dead end links online thus far.

I've just bought my iMac which came with no backup/bootable software discs at all (unlike new PC's). So from my over an hour reading from GOOGLE with conflicting answers from what I can gather "Time Capsule" cannot create a bootable copy of your hardrive ... So, I as have a 1TB harddrive with the iMAC some questions I have are :
1. ) Do I need to purchase a 2TB external hard drive (minimum) to create a clone of the current harddrive & any future information stored on it as I intend to backup once a month. It "MUST" be a bootable backup as I have no discs!
2.) Is there any "cloud" storage services that I can make a bootable backup on that which can be accessed later to download via another PC or MAC to a harddrive/memory stick etc. & then uploaded to the new replacement hardrive in my iMAC?
3.) Off the subject altogether but just thought of it! I hate the keyboard with the iMAC even though its stylish it isn't lit which isn't helping me at night! So when using my old keyboard (which does light up) can I tell the iMAC to use the sign in the normal place rather than the number 2 key as well as other keys which are in different places on the iMAC compared to a PC keyboard !!!
Info:iMac (27-inch Mid 2011), Mac OS X (10.7.3), 3.4 GHz Intel Core i7; 8GB of DDR3

I just purchased the SN 10.6 family pack and would like to make a backup of the Install DVD. I have several MACs in the family and want to make sure I have an extra disk in case something happens to the original. I have Toast Titanium and I believe I can make a copy of the disk. Will this be an exact copy and will it be bootable from the DVD drive on my iMac? Are there any special settings in Toast that I have to use.? I only recently purchased Toast and am not too familiar with it at this point.

I used Carbon Copy Cloner to create a bootable backup of my internal hard drive. I was wondering how you initiate the bootable backup if I do have an internal hard drive failure? Do I just plug the drive in and power the computer on? Are there any other steps/precautions I should consider.

Tried to create a bootable clone using Disk Utility & got this:“Restore Failure, Recovery partition restores can only be done on GPT partition maps.”I may need to purchase Carbon Copy Cloner ($40) or Super Duper ($28).I had been using my free CCC v. 3.4.7 to make clones of OS X 10.6.8 but now I upgraded to OS X 10.9.4 & got message that CCC not compatible with Mavericks unless I buy the CCC v. 3.5.6.I read several places that DU can do back up clones same as CCC or SD!I launched DU from recovery system, selected Mac HD as source & my XHD as destination. Both are formatted Max OS Extended (Journaled)So, what am I doing wrong?Also, what advantages, if any, are there in using CCC or SD instead of the free DU?

I'd like to create a bootable Snow Leopard Flash Drive, after upgrading to Lion. I have multiple Macs with some expensive legacy software and an Apple USB modem (32 bit) I use out in rural areas. I'm assuming this will be a viable solution

I have an '05 mac mini (pre-intel chip) with OS X 10.4 that while trying to transfer a file to an external hard drive gave me a blue screen (that wouldn't go away). After a hard shut down, I get to the apple and spinning wheel but nothing else happens.
My goal is to get to my files on the mini and put them on an external drive (specifically my itunes folder)
Is there some other way to repair this? I have 17 GB left on the main hard drive. Could I partition it and create a new bootable drive without wiping out the data in the original drive?

I just recently purchased a Macbook, and I created a bootable backup of the system. The macbook boots from the backup, but when I try to boot from the backup on our G5 and also our Powerbook G4 it will not work. The G5 does not even see the bootable partitions I created, and the G4 sees them, but when I select the partition to boot from, the computer just restarts and boots from the Powerbook hardrive. We are having to send the Macbook back for some small power issues, and we need a bootable backup of this sytem that works. Does this have anything to do with the fact that the Macbook is an intel based computer and the Powerbook G4 is not? Also, the macbook is running Snow Leopard, and the Powerbook is on Tiger.

I want to create a disk image of a Mac drive (.dmg file).I figured that it might not be a good idea to try and image a live disk, so I unmounted it (the user dragged the disk icon to the eject icon), and I confirmed it was unmounted by looking at /Volumes. To be clear here, this isn't the boot volume, that is /dev/disk0./dev/disk1 is an internal drive - as it happens it's the original drive for this OSX 10.4 G5, AND /Volumes/HITACHI is the mount point for an external USB drive.I have tried this twice.On both occassions, things seemed to go well, but after a few minutes (about 10 - 20 minutes), I observed that the target file on /Volumes/HITACHI stopped growing, then a bunch of unpleasant stuff started to happen:
* I did lsof /Volumes/HITACHI/MacHD_20120201.dmg and found the PID of the diskimage binary, ps waux showed it was doing nothing (CPU% was 0.0). This indicates a stuck process to me.
* The hdutil command stopped producing '.'
* I could not cancel the hduitl command
* I could not rm the MacHD_20120201.dmg file
* I could not ls the /Volumes/HITACHI directory
* unlink also hung
A little further into this, the Mac became unresponsive. I observed that the disk was now mounted again (grrr!). As a work around I switched the USB drive off and on, and Mac came good - all my terminals started to respond, the GUI responded for the user.My workaround has been to use CCC to make a clone of the disk - but I don't like this because I think .dmg files are much more convenient (for a start, now that I've used CCC I can't use the USB drive for anything else).
* Is my methodology wrong? Do I really need to umount the /dev/disk1
* Can you disable finder from automounting an internal hard drive (I am particularly interested in this)

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)? Also is a .toast extension a bootable file on the mac?

I would like to make my usb memory bootable. Is it any way to get the drive to show up in startup items in sys.prefs? I have tried with fdisk, hdiutil and diskutil but have not been able to select my drive. I thought it was going to happen with fdisk. Typing fdisk /dev/disk1 gives me this.

I used a program called carbon copy cloner to make a clone of my father's mac book pro onto an external hd usb. I already erased the laptop so I can't go back too it for another copy so I'm stuck.
Anyhow, all the data copied over nicely. However it said it will make the drive bootable. But it does not. I partitioned GUID so it should boot cuz intel macs can boot usb if partitioned GUID. But it won't boot on the macbook pro intel or my mac mini intel. Both core duo (not 2 duo). And I can't reinstall because the dvd is 10.5.0 and we have 10.5.8 on the external.
Unless there is a way to remove 5.8 and go back to zero but I don't hink so. I did Disk first aid and it says the drive is fine. It is brand new. And it won't let me verify or repair permissions. Don't know what to do.

I tried to install ubuntu with bootcamp on a different hard drive. Something happened and now when I turn on my computer it says no bootable devices. It doesn't even see my OSX hard drive. I tried booting up my computer and holding down option. It doesn't work. I have a wireless microsoft keyboard. Is it not letting me hold down option because the computer finds the wrieless keyboard to late. Some one said u have to hold down the option key before the mac sounds happens. The keyboard lights don't come on till after that. Should I get a USB keyboard? I have to press the start button on the keyboard to act as the option key when I'm in osx. Would the computer know that the start key is the option key on boot up?

Been searching for the answer to this question, so far to no avail. How can I create a bootable disk with Disk Utility on it? I need to run Disk Utility to repair my main startup disk on my G5 tower, which is running tiger 10.4.11. I do not have access to the original system installation disks for this computer. I also have an early Intel Dual Core tower running Tiger 10.4.11. That machine has Toast Titanium version 8.0.1. Also no access to the system installation disks.

When I first got Leopard I restored an image onto my new hdd before I used it as a time machine drive. Does anyone know what will happen if I restore an image of snow leopard onto it and uncheck the erase drive option? Will I just have a bootable time machine drive w/ SL or will I mess up my TM backups?
