Create bootable copy of bootable disk

I have a bootable Linux disk that I would like to make a copy of. I only have one drive in my iMac so I was planning on using Disk Utility to make an image of the disk then burning that image. If I do that will the copy of the disk be bootable or will I lose that functionality through the copy process?
If it doesn't keep it bootable whats the best way to make a copy of a bootable disk.

In addition to a brody's good advice, you can try this method:
http://docs.info.apple.com/article.html?artnum=42724
It talks about DVD-R video discs, but I have used this basic method to make a copy of my Tiger install DVD to keep in a drawer in case my original gets lost/broken. The result was bootable.

No option to create bootable disk.

Intel MBP with Mountain Lion. Using the assistant to bootcamp but in the select tasks menu, I only have two options to download Windows support software or to install Windows 7. I have no option to create a bootable disk, which I need to burn the iso onto a USB hard drive. Is there any way of fixing this? I've tried creating a bootable disk on another laptop but I can't boot from the external disk either.

As you now the option is unavailable for machines that have optical drives but you can do a tweak in the info.plist that makes it also possible for you too.

Create Bootable Copy of OS 10.6 Install Disk

I purchased the family pack of Snow Leopard 10.6. I tried to make a backup copy of the disk in case anything ever happened to it. I used disk utility to create a disk image and then burnt it to a DVD. When I tried to use the backup disk to install OS X 10.6 on my Macbook, it would not reboot into the OS X install after I clicked install. I was doing an erase and install and when it said to restart I did so, but it only booted back into 10.5 and the disk image mounted. It is obvious I did not create a bootable copy of the disk image. Can anyone give me some help on how to do this so I could install from the backup disk in case the original was damaged somehow? I did use the original and had no problem with the erase and install.

Thanks, I will try that. The DL DVD disks are good and have not failed me yet..
well, good for you but I had to burn through several of them once to make a working copy of the leopard DVD. they are not cheap so the price adds up quickly. since then I use the method suggested by hatter. I have small partitions on one of my internal drives with copies of the leopard and snow leopard disks. they are VERY fast. leopard install takes about 20 minutes and it will probably be even faster with snow leopard.

Disk Utility: Restore no longer creates bootable images?

So I have a new hard drive for my macbook, and followed the procedure I used last time of using disk utility restore to write the current hard drive image to the new disk, with the new disk in a USB enclosure.
I have done this before, it creates a bootable copy on the new disk, swap the disks away I go.
This time however the new disk is not bootable. When starting it gets to the grey screen with the rotating white pips then dumps back to a black screen with error messages (like its trying to boot of the network).
Swapping back to the old disk boots just fine, so its a problem with the image written to the new disk by disk utility restore not being bootable.
Is this a known issue? I searched the forum with no answers, and am frustrated that its now working as I have run the image twice now at about 5 hours a go for 100GB of data so I am sure its not the copy. Straight after the copy the original disk has about 10 more files than the new disk that's just been imaged, has their been some update to disk utility in the OS X patches that means it no longer copies some key files?
Note that partition on new disk is GUID as it should be, and I don't want to re-install anything from the install media I want to use make disk utility work as designed.

I found two references that may help:
A) At http://everythingapple.blogspot.com/2007/11/use-powerpc-mac-to-create-bootable.h tml it says "PowerPC Macs use the Apple Partition Map, but this poses no problem for Intel Macs, even though Intel Macs use the GUID Partition Table. The reverse is not true however. PowerPC Macs cannot boot disks with a GUID Partition Table."
1. Open up Disk Utility and select your backup drive. Select the "Partition" tab.
2. Go to the "Options" and choose "Apple Partition Map", which is the partition type necessary for PowerPC Macs.
B) Carbon Copy Cloner - Red Dot Warning on main screen: "The target volume will not boot this computer because PowerPC Macintoshes cannot boot from USB devices."
Looks like I'll have to install the 2.5" SATA drive into my PowerPC MacMini to upgrade my system volume from 80gb to 320gb.

Question about creating a bootable disk image in Leopard.

I have a Powerbook G4 that originally came with OS9, I upgraded to Tiger and recently upgraded to Leopard. The computer is running great but if it should go down what are my bootable options?
1) Boot from the install disk set then load tiger upgrade then load Leopard upgrade? then reload all my programs back on the G4?
2) Can I create a bootable disk image and save it on an external hard drive and then boot and reload everything at once? ( I guess by asking this question I really don't understand what the full scope of a bootable disk image is?) can someone explain...
Which option is better? I am also running __time machine__... what is the safest and easiest way to use time machine to get my software back together after I get the operating system up and running.
Thanks for the advice

Your best alternative is to create a bootable clone on an external Firewire drive.
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the backup or destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
6. Select the startup or source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Of course you can use other software for cloning and backup:
Backup Software Recommendations
My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
8. Intego Personal Backup (Commercial)
9. Data Backup (Commercial)
For use with Leopard always be sure you use a version of the software that is compatible with Leopard.

Bootable Copy of Installation Disk

I have made a backup copy of my Leopard Installation Disk by the following method in order to make it bootable:
1. Open Disk Utility
2. Highlight "Mac OS X Install DVD" in left pane.
3. From the'File' menu choose "New -> Disk Image from disk 3s3 (Mac OS X Install DVD)
4. In the 'Convert Image' window give the image the same name as the Install DVD
5. For 'Image Format' select "read/write" For Encryption select "none"
6. Save the Image
7. Select image and 'Get Info' and make sure image is locked under 'General'
8. Highlight the image in Disk Utility and then Burn using a dual layer DVD
Having done this I tested to check that the disk was bootable by trying it in my 20" iMac 2.16 Core 2 Duo running 10.5.6 - Success !!
However....
I then tested it in my 15" MBP Late 2008 unibody also running 10.5.6 and it would not boot from the disk.The MacBook Pro attempted to boot from the disk but just got into an endless cycle of attempting to reboot.
If I go to Startup Disk in System Preferences the disk shows up as a viable system to boot from - but again will not start from it.
The MacBook Pro will start up from the original Installation Disk.
My question I suppose is does anybody know why this is happening ? Is there something in the new MacBook pros that stop this deliberately?
Is there a better way to make a bootable disk? - expensive for me to keep trying different methods.
If somebody has managed to make a bootable disk for a similar machine I would be interested to know exactly how they did it.
Many thanks
Adam

Thanks again - I had suspected the DVD media as I have tried to use cheaper brands before.
On this occasion I have actually used Verbatim DVD +R discs - I guess I will just try to burn another with the same method and keep my fingers crossed.
Thanks for your suggestions
Adam
When you burn the new DVD, let the verify run completely. I usually stop it, but in your case, you really want to know if the copy if bit-for-bit identical.
I would also not that I do not use Finder and the built-in disk copy app, but I use Toast. I had some problems with using Finder as a copying tool early on and when I got Toast for other reasons, I just never look back at the Finder disk copy.

Create a bootable disk in mavericks

I want to create a bootable disk in Mavericks. I plan to do this on a LaCie Thunderbolt SSD drive.
Is this possible?

If you want to boot on a disk, you gat to have an OS on it.
First, with the disk manager you resize your disk and then use bootcamp to build it as a bootable device.
The nature of the disk you're using doesn't mater.

How can I make a bootable disk for Mountain Lion?

How can I make a bootable disk for Mountain Lion?

Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.

Bootable disk

Ok, so i feel like this is a really stupid question, but can someone tell me how to make a bootable disk in disk utility and the button combination when you start up. I just had to repair my disk and had to go to apple because I couldn't find my disks.

Disk Utility can clone (restore) a bootable disk or an image of one to another disk, making that disk bootable, but it can't build a bootable disk on its own without one of those sources. (Think of it kinda like an office copier: it can make copies of what you feed to it but it can't make originals.)
If instead you mean how can you repair the normal startup disk in your Mac without any of the installer DVD discs or any other already created boot disk of some sort, the answer is you can't. A disk must be unmounted (taken offline) to repair it, & the startup disk (or the disk containing the copy of Disk Utility you are using) can't be taken offline.
For this reason (among others) you should always have your system discs available. If you have lost yours, you can order a replacement set from Apple for a nominal cost.

Since you seem to be using a new disk for Lion, Time Machine will consider previous backups to be for a "different" computer. Try doing a control-click or click-and-hold on the Time Machine icon in the Dock, then choose "Browse Other Time Machine Disks". This should allow Time Machine to see the previous backups.
In the worst case you should be able to open those Time Machine backups and copy your documents from there to your home folder.

Bootcamp Install, No Bootable Disk

Hi,
I was just in the process of installing Windows 8 on my Macbook Pro Late 2011 15" when after i partioned the hard drive, and restarted i had the no bootable disk error, with the black screen. I was attempting to use the Windows 8 ISO on a USB stick to boot, and presuming that it wasn't reading the ISO on the usb stick went on to burn the ISO onto a disk instead. But that hasn't worked either.
I'm now in a sort of limbo where i can't remove the partition that has nothing on, as the boot camp assistant won't allow me to remove it, and there is a device called Bootcam sitting in my Devices tab in Finder with the 125GB partition.
When I shut my mac down now it doesn't even attempt to go to the No Bootable Disk screen but goes straight to Mountain Lion.
Is there anyway I can restore the hard drive to the single volume and try bootcamp again? Or even get the burned disk working with the Windows 8 iso on?
I'm really struggling here so any help will be much appreciated.

Edit: I've managed to return the hard drive to a single volume,
I'd like to point out i'm using a MSDN copy of Windows 8 Pro 64 Bit,
Is there anything obvious that I did wrong the first time? I recall the bootcamp assistant not being able to find the ISO before i partioned the hard drive, until I chose to mount the ISO from the USB stick. And then obviously when i tried to boot it it wasn't mounted anymore. But then surely when i burned the ISO onto the disk it should have read it from there?

"No Bootable Disk" Error Message
I determined my hard drive was bad and was able to create the 4 recovery disks. I installed a new 500GB WD Scorpio Blue hard drive. I ran the recovery disks, which formatted the drive and installed the original software. At the end of hte 4th disk, it says to remove the CD and restart. Upon restart, I get the message, "No bootable disk."
I reset the BIOS to factory settings, ran hard and memry tests and both checked out OK. Using DOS prompt, I ran "dir c:" and there are 7 DIRs with only 59,704,172,544 bytes free (shouldnt there be 400+ GB?)
I then created a Windoes 7 - 64 bit repair disk from my desktop. After choosing English, there are two Operating Systems listed - 1) OS: Windows Setup, Prt Size: 69631MB, Location: (Unknown) Local Disk, and 2) OS: Windows 7 Home Basic (recovered), Part Size: 69631 MB, Location: (C Local Disk.
I chose #2 and it found a problem with the boot files and corrected them. I restarted wihout CD, but still, "No boot disk". I re-ran the repair disk and chose "StartupRepair", but it found nothing wrong. I even tried choosing #1, but the message I go there was something like, "recovery is unable to correct this problem, do you want to send info to Microsoft".
I suspect there is something amiss with the partitiob, but again, when I ran the recovery, it formatted the new drive and installed files.

Get Partition Wizard Bootable CD ISO and ImgBurn to burn the iso image to cd and boot from it. Delete partitions, create one and format. Next try booting from Recovery again.
Be sure that the wireless is turned on when running Recovery.

"No bootable disk.." problem. Help? :(

Hello there,
I have been trying to install Win 7 on my MacBook (not sure what year, but it's a Snow Leopard (10.6.8), 2.26 GHz Intel Core 2 Duo (64-bit), 2 GB memory) and every time I try to install Windows I get the same message. I tried Win XP and Win 7, same thing in the end.
I have successfully created a partition for Windows and when I click "Start Installation", with the DVD with the software inside, the computer reboots and it gives me "No bootable disk - insert boot disk and press any key" every time, with both versions of Windows.
I have searched a lot and I even called Apple Support and Microsof Support, but I don't need to tell you how helpful and time-consuming that was.......
I can't seem to find a solution to my problem.
Please, don't be rude, keep it to yourself. I'm not a Mac or MS guru, but I have my way with things.
Any help will be appreciated.
Thanks!

I figured it out, apparently I haven't burned the .iso file correctly - I have just burned it on a DVD without making the DVD bootable. To not repeat my mistake just open "Disk Utility", drag the .iso (software) file in "Disk Utility", insert a blank DVD, Click Images in the upper left and then click Burn. This way the files are burned on the DVD correctly and are bootable.
Thanks!

Making "bootable" disk

Norton's Disk Utility (V8.x) has OS9 and OsX boot images on the disk to boot into either system for their respective disk utilities.
I would like make a "backup" copy of the OS9 version to a separate disk to keep with my OS9 software collection.
I have tried Disk Utility (V10.4.4 on my Dual G4) and a couple of different "cloners" with make bootable option ticked and burnt thru Disk Copy, Toast 6 Titanium and Dragon Burn) to no avail.
I have made "bootable" disks before but can't remember the procedure (getting "old timers", I think :))
Maybe this version of Disk Utility (10.4.4) won't let you do bootable copies?
(Note to above - when formatting HD's with this version of Disk Utility, I did notice that there are no options in formatting/partitioning a disk to load OS9 drivers even though I am running OsX 10.3.9 - all updates)
Any suggestions would be appreciated.
Thank you - Ron

First, I hope you don't use Norton Utilities with OS X. It's incompatible and not supported. NUM can damage your OS X disk.
If you need a duplicate of the OS 9 disc try the following:
Duplicate a CD or DVD
1. Insert the DVD/CD;
2. Open Disk Utility, and select the DVD/CD from the left side list (select the DVD/CD icon on top);
3. from the DU File menu select New | Disk Image from Disk 1;
4. Choose to format the disk image as DVD/CD Master, name the disk image and click Save;
5. When the .cdr file is finished select it with mouse and press COMMAND-I to open the Get Info and check the box to lock the file;
6. Choose the .cdr file from the left side list, click Burn, and insert a new, blank DVD or CD.

Need a simple, free program to make bootable disk image.

Folks,
I'm looking all around for a freeware backup to create simple, bootable disk images for both Win7/64 and XP/32 builds. Nothing fancy, just as a disaster backup for the seven computers I'm zeroing out and re-loading for my math class. My builds are straightforward single-partition, single-disk machines.
I need to keep these machines clean and the school's network uninfected, so if I suspect an ugly virus or porn has sneeked in on a thumb drive my hope is to zero out the drive and simply re-load. I haven't yet had the pleasure of trying to re-load from a disk image.
I've got 40 hours into this project and am ready to backup all of them. I'll probably do something rash if another glitch causes me to re-load for the nth time this week. Freakin' 10 hours a day at it! (Please - don't even ask about the deadline today in getting my XP Service Pack 2 machines updated before Microsoft ends support for SP2....)
Luckily, Win 7 has a disk image applet I've used to create a disk image on an external drive and a recovery disk for these builds. I hope this built-in feature is good enough.
My three XP builds have no such luxury, so I'm looking for a freeware app to create bootable recovery disks on DVD. The full XP load is only about 10GB, so this is merely three DVD's.
I've gone all 'round the net, checking out reviews. Anybody here have a favorite? I do see a vote for Terabyte in Harm's "Favorite Tools" thread.
