Mac Mini i7 (Mavericks) will not boot from the external drive

Mac Mini i7 (Mavericks) will not boot from the external drive with Disk Warroir 4.4. or Drive Genius or Lion.
Not even from the external Firewire hard drive with Mavericks

Does the external HD have a GUID partition table?
Is the external drive formatted Mac OS X Extended (journaled)?
Is this a 2011 or late 2012 Mac?
How was Mavericks installed on the external drive?
Who is the builder of the drive mechanism in the external drive?
Who is the builder of the external enclosure?
What type of interface does the external drive have USB2, USB3, Firewire 400, Firewire 800, thunderbolt?
Is the external enclosure directly connected to the mini?
Have youtried a different interface cable?

Help needed on startup. My computer will not boot from the CD drive!!!

Problem with iMac G3 333, the Message on the screen states: "The System Software on the starup disk only functions on the media, not if copied to another drive." Like a fool, I copied the system folder from the original system software 9.2.2 on to the iMac. System disk which is not a complete system folder when used on the computer. I have searched the Internet, but can not find an answer. I have tried everything, holding down the C key, "Delete, Opition, Apple key, shift" holding the mouse down on startup, various combinations of other keys, etc. The CD starts to spin, but the computer switches to the hard drive and the message above returns. No matter what I try I still can't boot from the tray loading CD drive. Is there any Firmware code that I can use. I know how to access Firmware on the Imac and can boot the iMac using Firmware, but I don't know how to use Firmware to boot the CD drive which I need to do so I can reload the original software. CAN SOMEONE PLEASE HELP? Thanks, Jim

Yes, I have tried both System Softwares a number of times. The C key will not boot up the CD drive and the harddrive always boots with the original message. I need to get the CD drive to boot so I can reloaded tge original software. Do you know anything about booting the CD drive using Firmware? Jim

Intel Xserve will NOT boot from hard disk drive

I have two Intel Xserves 2.0 QC machines
I have tried to re-install version 10.4.11 OS (don't ask) onto a Hard disk drive that is in a Disk drive caddy and inserted in the machine.
When booting from The installation DVD media
The disk is seen by the "Disk Utility" (the disk is partitioned as GUID boot) and the installation proceeds to the disk.
Once the first pass of the installation is complete and the system reboots, the system shows the folder and ? mark.
If I boot and hold "ALT" key to view all avaialble boot options the Hard Disk Drive does NOT appear as valid boot disk.
It does show, the still inserted Installation DVD.
I CAN boot from an external firewire drive and the Hard disk drive is visible to the OS once logged in.
I have tried different caddy postions (left, middle and right)
I have tried bona fide Apple supplied Disk drives
I have tried various different caddies
I have tried installing Operating System 10.5.* and 10.6.8 server
I have run SMC reset and system reset
But still I cannot boot off from any Hard Disk Drive inserted in a caddy at the front of the system.
Has anyone seen this behaviour?
Is it fixable?
Do I have replace something like the Hard Disk Drive back plane circuit board? Or even the main logic board?
I have now run out of ideas and cannot find any help in discussions or just googling.
ANY help would be very appreciated
Regards
Tony

Antonio Hi !
QC = Quad core or QX as it is written on the "pull out" serial number tab at rear of system
I have 3 late 2006 Intel xserves
On my intial posting I declared 2 were 2.0 machines - when I was trying to be concise
2 of the macines are 2.66 systems and 1 is 2.0 system - all are QX machines
the 2.0 and 1 of the 2.66 will NOT boot from the ADM and disk inside the system - whereas the other 2.66 system will.
I have many different Caddies and these have different product/model number labels
603-9965
603-9545
603-9796
these are marked "intel SATA"
The 80Gb was only one of the drives tested - I have used Seagate 400Gb 750Gb and 1Tb - all of which have been used in systems at one time or another
and as I said the drives ARE visible once the operating system (either installation DVD or external firewire are booted from) - they are just NOT visible when the system is searching for boot media.
Thanks for the guide - I will look through that and continue to try and find an answer

Will not boot from CD/DVD drive even with "C" key pressed

I have a G4 with a hard drive that is (apparently) dead. I would like to boot off the CD drive, but that does not work. I press "C", then turn the power on, continue holding down the "C" key, and the hard drive just makes some clicking noises for about 20-30 seconds, then gives up. The computer will not boot at all. Same thing happens when holding down "Option" instead of "C"
Why would the computer not boot off the CD drive?
Any tips would be greatly appreciated. Thanks!

OSX 10.4 not booting from an external drive..

I have an 1 Ghz G4 iMac that is causing some major headaches.
It started by the machine crashing every 15-20 minutes.
A fresh re-install seemed to be the best option.
In order to sort out the problem I decided to install a fresh copy of OSX on an external firewire drive.
The install went without any problems but then I was unable to boot from the firewire drive.
Even holding down the option key and selecting the drive manually didn't do anything.
I then decided to do an archive install on the internal drive. This crashed in mid-installation making the internal drive in-accessible.
Anybody have any tips on how to get out of this mess?
E.

Since your machine crashed while running from the install disc, it sounds like there is a problem not related to the Operating System on your drive. Have you installed any ram, other than that which came with your iMac? If so, remove it and try to boot from your firewire drive again. (The installation onto that drive was sucessful, right?)If you're successful in booting the computer and it runs with more stablility minus any extra ram, you have a bad ram stick.
My fear here is that since your previous re-install failed I'm not certain that another attempt to install on that drive wil save all your stuff... if you can boot from your external drive, I'd rescue your data, photos, music, etc., to the external before trying to re-install on your internal drive.

Mac Mini (PowerPC version) will not boot - or reinstall...

All of a sudden my MacMini is playing up. It will not boot. I have tried leaving it overnight and reinstalling the OS to no avail.
It boots from CD and reads the install disc, but it hangs everywhere for ages. It verifies the install DVD - then just fails to install. And I have tried installing to external USB drives too with the same result.
I have run DiscWarrior twice and that sees no problems...any ideas? Any help will be greatly appreciated,

Satellite C655D-S5303 will not boot from cd/dvd drive

I have already set the boot order in the BIOS to boot from cd/dvd drive first and it still goes straight to the HDD and starts Windows 7. I searched for this problem and found some people saying to switch it to CSM boot or disable secure boot but none of these options are available in the BIOS. I have it set to normal boot instead of fast so thats not the problem. Can anyone help me here? I am trying to reformat and reinstall Windows 7. I know the Windows 7 installation disk I have is good because I have used it in another computer and the cd/dvd drive works fine. I just can't get it to boot from the cd/dvd drive before the HDD.
Solved!

Try setting the HDD to lowest boot priority. See Dave's solution in this message.
It's certainly easier to restore the hard disk to its original out-of-the-box contents using Toshiba recovery media. All the drivers and utilities are preinstalled in the proper order. Windows is preactivated.
If you failed to burn recovery discs, you can obtain recovery media from Toshiba. Scroll down to Get Recovery Media here

Mavericks will not download from the App store. Repeatedly receive a message that "an error has occurred. Try again"

I have repeatedly tried to download Mavericks from the App store. When attempted from the update tab it fails and instructs me to try again from the Purchases tab. When I try it there, I receive an error message that "an error has occurred" and to try again. I have successfully downloaded other apps (both Apple and third party) but Mavericks won't do it.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Start up disc problems and my imac will not boot from the cd.

Hi All,
I have a start up disc that needs repaired, according to ONYX so then reading the apple support guide it seems I boot from my OSX CD that came with my iMac and use First Aid. However when I insert my OSX CD my imac reads it fine, as it does with any other cd, yet when I re-boot, holding down C, it won't boot. It restarts, but fails then to read the CD and just re-boots again, and again, and again.
How can I fix this?
Thanks all, I appreciate it.
From abour this MAC:
OSX 10.6.8
2.93 Ghz Intel Core 2
8gb 1333 DDR3
Start up disc Mac HD

thanks, but disc is spotless.
When I put the disc in while machine is on it is read perfectly, appears immediatly and can be opened with no issues. It is only on re-boot ti then appears not to engage with the system.
I was advised to re-boot holding the "c" button from the MAC forum which I have done. I have also restarted using the restart button on the OSX disc loading screen.

Power Mac G4 400 MHz (AGP graphics) will not boot from hard drive

I have a Mac G4 400 MHz (AGP graphics) Machine Model: PowerMac 3.1 CPU Type:PowerPC G4 (2.8)
When I try to boot from the hard drive I get the folder with the flashing question Mark. The Machine will start up from the OSX 10.4 installer disk.
The system was running OSX 10.4.9 fine. I began to have problems with the hard drive, so I replaced it with an old Maxtor 5T040H4 40Gig Apple branded drive that I had sitting around.
The drive is jumpered (r50) for Master/Single.
I erased the drive in the old G4 using disk utility and wrote all zeros. I then used my store bought Tiger 10.4 install disk to install 10.4 on the drive.
After restarting I still get the flashing question mark. If I leave the Install disk in the DVD drive the system will attempt to install again.
I have zapped the PRAM, pressed the CUDA button, removed the battery and let the system sit unplugged for over and hour and it still will not boot from the hard drive.
To test the drive I removed it and put it in a Granite Digital firewire enclosure and connected it to another mac. The drive shows up and the system appears to be installed correctly.
What am I forgetting to do? Does anyone have any suggestions.
Thanks in advance.
Wesley G.

Hi! If Tom's solution doesn't work I would reboot from the install disc and then partition the drive as 1 partition instead of erasing it. Sounds like the driver on the disk is too old and installing a new partition map should write a new driver to the drive that is compatible with Tiger. Other than that it is possible that the drive has a spin delay jumper enabled and the drive isn't spinning up fast enough and the computer isn't looking long enough for the drive. Tom

After 10.5 upgrade Mac will not boot from hard drive

I just upgraded to 10.5 Leopard but my mac will not boot from the hard drive even after selecting my hard drive as the startup disk. The mac will start to boot but will cut itself off before the boot is complete. I have to leave the Leopard disk in the mac and hold down C to get the mac to turn on but it only allows me to install the software again.

instead of archive and install you might first want to try restoring your system using TM to some time point before your failed 10.5.1 upgrade. Then try upgrading to 10.5.1 again. I would suggest downloading the full 110 MB upgrade and installing it manually rather than doing it through the software upgrade menu.
You can download the upgrade here:

Absolutely will not boot from cd or dvd

Someone has given me a Sun Ultra 10 workstation ... problem is that no matter what I do this machine will not boot from the optical drive. Extremely fustrating. The errors I am getting are "Bad magic number in disk label" and "Can't open disk label package" and "can't open boot device".
I have tried three seperate drives, three seperate IDE ribbons, and three different disks. I have tried on both IDE channels, master and slave. The cdrom alias seems to be hard set and does not change when I change its position on the bus. A combination of devalias, probe-ide and show-disks helps. What happens when I try and boot from the correct device is that the disk spins up, I get the error(s) and thats it.
I am aware that there has been a lot of discussion about this in the past and have spent absolutely ages reading pages from google results but none of it seems to help me.
Can anyone shed some light on this for me? It would be greatly appreciated. Thank you :-)

Just checking that you are trying to boot from a Sparc version.
I checked what happend with boot cdrom -s on a Sun Ultra 10 from a X86 Solaris DVD and got the errors:

Elitebook 8440p - recovery disc creation & booting from an external drive

I have a brand new Elitebook 8440p & I have a couple of issues that I cannot seem to resolve.
1. I expected to get some sort of system install, or recovery or repair discs - or the ability to create such disks with this laptop. Nothing came with it, and I cannot find any place to create some sort of system recovery disks, nor is there anything listed for this laptop on the HP site to acquire them from HP. I am not comfortable having no way to recover this computer should a hard disk go south. Any ideas how to create or get an op system disk or recovery discs or something?
2. I have an encrypted company/business hard disc inside the laptop for work. I also have the original hard disk that came with the computer in an external eSata/USB case. I have configured and installed software on the external drive to include my personal software and programs, leaving the company hard disc inside the laptop for business use only. However, I cannot make this laptop boot from the external drive if the company drive is inside the laptop. I have read and tried everything, but if a drive is inside the laptop, it will not boot from the external eSata/USB drive. If I simply remove the laptop hard drive, it boots perfectly from the external drive via eSata and works fine. How do I manage to get this laptop to boot from my external drive without having to remove the internal hard drive?
Any help or ideas someone can offer are greatly appreciated. Thanks very much.

Hi, Rich:
If you live in the USA or Canada, you can get a set of restore disks from HP for $10. I am surprised you didn't get a set but maybe they only come with the business desktops.
Here is how you order them:
1. Write down the part number and serial # on bottom of the computer on the white tag. The model # is an HP-Compaq 8440p, but the part number will be found on that white tag below the serial #.
2. Call HP at 1-800-952-7689, option 1 (ordering restore disks is part of the list in the option).
3. Provide the info asked by the rep that answers the phone. Some just ask for the serial #, some want both, or they will just want the serial number and type of computer (8440p).
4. Have a Master Card or Visa ready for purchasing. They don't take Discover. You will be charged $10.00.
You will receive the disks by First Class Mail or you can pay an additional $10.00 for FedEx shipping.
Sorry, I can't answer your second question. I assume you have already tried hitting the F9 key at the HP splash screen to select the device to boot from?
