Can no longer boot from ANY OS disc on MBP

I recently purchased a 15" 2.16ghz Core Duo Macbook Pro. It came with the original 10.4.5 discs. The previous owner installed 10.6 on it using a retail disc, then upgraded to 10.6.6. I had planned on upgrading the original hard drive. However, I cannot get the laptop to boot from the original discs or my own retail 10.6 disc. I've tried a number of different approaches (booting from an external DVD, holding down "C", holding down "option", attempting to mount in on the desktop first, etc.). Either the machine hangs or it ejects the disc (when using the internal drive). Nothing seems to work. Both the internal drive and external drive have been tested and work fine. Is it possible that when upgrading to 10.6.6 a firmware upgrade was done that won't allow the machine to boot from a disc containing an earlier version? I don't know what else could be causing the issue. The laptop has not displayed any other issues. Thanks for any suggestions or explanations.

I don't know how much help I'll be to you. Seems to have a lot of posts lately about not being able to start up from the install disks.
I assume you can still boot up from the internal drive.
When you hold the option key to start, does the screen come up with the option to choose a startup disk and is your Install Disk in when you attempt this?
While booted up normally, does the Install Disk open up with the install OSX menu? If so, does going through the install menu reboot the computer from the CD automatically?
Even if there were a firmware upgrade, seems like you would be able to use the 10.6 Install Disk to boot from.

G4 won't boot from any Linux disc I put in it and c key no longer boots cd

I have a G4 Powermac (sawtooth, DVD drive, 512 MB RAM, 30 GB HDD) which has started refusing to boot from any Ububtu discs I have all of a sudden.
I'll be more specific. I've previously been able to boot from Ubuntu 6 cds (originals from shipit, not burnt) as well as Ubuntu 7 (burnt disc). I haven't made any changes to the system that should stop it booting from them. Currently installed on the hard disc is System 9 and Puma. It is still booting ok from my System 9, Puma, Panther and Tiger discs; but when trying to boot from my ubuntu discs (I've tried all of them to eliminate the possibility of a stuffed disc) the screen goes black for a second as if it is starting to boot, but then it kicks me to the flashing folder screen you get when it can't find a startup disc. Oddly enough the background colour of this screen isn't grey like usual. It's orange. I've never seen that before. If I leave it sitting at this screen after about 30 seconds or so it starts up from the hard disc on its own.
Another odd thing: the c key no longer forces the machine to boot from the cd when held on power up. This is extremely odd, as holding down option brings up the startup disc selector, and cmdopt+shiftdel also works. I've tried everything I can think of. Used a different keyboard, reset the NVRAM (by cmdopt+pr and my manually going into open firmware and doing a "reset-nvram" and "reset-all"). I've tried the PMU reset switch on the logic board. I've tried using different drives. In all cases it still refuses to boot from cd when holding c.
I don't think that the mac refusing to boot while holding the c key is coincidental. I believe that whatever the issue is that's causing this issue is what is also causing the mac from not booting any Ubuntu discs. It's a very strange problem and upon searching around, it seems this doesn't seem to have happened to anyone else before. Any advice will be greatly appreciated. Thanks.

Hi, yoshi -
I just have to be rush to get the cd in the drive and then to hit cmdshift+optdelete before it's too late...
You should also be able to use Startup Manager to choose the CD as the boot volume -
Article #HT1310 - Startup Manager: How to Select a Startup Volume
A feature not discussed in that article -
Once Startup Manager has loaded, if the CD is not in the drive you can press Command-. (Command-periodkey) to open the drive - this should work even if another disk is already in the drive. Insert the disk you want to use, close the tray, wait a few seconds for the disk to spin up and get recognized, then click the circular arrow icon on the left - this forces a rescan of the available drives, which should result in an icon of the new disk appearing in the array. Click it to select it and then click the straight arrow icon on the right (or press Return).

Can no longer boot from DVD or USB HD since installing Win10

5/2/15
I download and installed the latest Win10 last week and popped it on a spare HD I have in the system;
the mistake I made was to leave my SSD which has Win7 on it connected during the install.
Now I’m in a bit of a pickle. When I boot up with the Win10 disk disconnected I get a splash screen that tells me:
A required device isn’t connected or can’t be accessed. It offers me an option to press F9 to boot to another OS and indeed it does boot me into Win7 but insists all my hard drives need a chkdsk. They are fine
So I thought I’d simply boot from a DVD or USN drive and “fix” the Win 7 install.
Lol , it won’t boot from a DVD or the USB HD. If I pull the Sata cable from the SSD containing Win7 it boots right up from either the DVD or the USB HD.
I’d really not like to do a clean install of Win7 on my SSD just to get around this.
When the drive I loaded Win10 is connected it still won’t boot from a DVD but does allow me to boot into 7 or 10.
Yeah, yeah I know I should have installed it in a VM but I didn’t. Any suggestions?

Can no longer boot from hard drive

I wanted to get my MacBook Pro (OSX 10.6.8) to boot from a CD, which it did (turns out CD was faulty and didn't work). In order to do this I went to the System Options and selected boot from Disk option.
Only problem is now my Mac will only boot from a CD and not from the hard drive! How do I get it to boot from the hard drive again?

Hold down the option key while booting, then you will have your selection again.
Once in OS X, set it as the boot disk in System Preferences.

G4 Won't start. Won't boot from any disc (OS 9 or Linux).

I recently acquired a Power Mac G4 from my school, as they did not need it. The computer was a donation to the school, so the hard drive was removed and destroyed.
I found a hard drive for it, and hooked it in and it seems to be running fine. However no matter what I do, it will not boot from the disc drive. I have tried holding "C" while it's booting, and the screen goes white for a little while,and then it switches to the flashing Finder icon and question mark. I have also tried the Startup Manager, but it doesn't show that there are any discs whatsoever. I looked around and found that the Open Firemware may help. But I can't get into it using the CommandShift+OF command. In fact, the only time i got into it, was when I mashed a bunch of keys at once, and it came up. But that hasn't worked again.
Also (I dont know if this matters) but when I press the Power button, I don't hear that ever so wonderful, startup sound. And Ive tried to boot from the internal disc drive, and an external Sony drive.

The Mirrored Drive Doors G4 models (and possibly the quicksilver 2002 models) are unable to boot OS 9 from ANY "Full Retail" CD. These Macs came out after the last versions of "Full Retail" 9.2.1 were issued, and if you bought one of these advanced G4s new, it came with a set of discs that contained a customized 9.2.1, so no new "Full Retail" OS 9 CDs were needed.
If you could post the CPU speed (check the label on the back), readers can figure out exactly which Mac you have and determine how much trouble you are in.
Can you get a Mac OS X 10.2 or 10.3 "Full Retail" CD from the school? They should have trunks full, and think of them as antiques.

G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
We were in the process of installing 10.4 Tiger before placing it for sale.
The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
We have done the following during our troubleshooting:
- Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
- Remove RAM 1 stick at a time and reboot
- Replace RAM with RAM from another working Quicksilver
- Replace Video Card with one from another working Quicksilver
- Zap PRAM
- Reset CUDA switch
- Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
- Tried booting from the Macintosh Server G4 Software Restore CD
- Tried booting from Mac OS X Server CD
- Tried booting from AppleCare Protection Plan CD with TechTool
- Tried booting from Diskwarrior CD
- Tried booting from an external FireWire drive with a disk image of Tiger OS Install
- Tried booting with the hard drive disconnected
The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
I would look at the CD drive cables, etc, and see if another drive gives different results.
You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

128gb ssd on macbook pro can't boot from any win dvd

Like in title, installed 128gb ssd on macbook pro and can't boot from any windows based dvd.

I was try to boot with win7, vista, xp and other boot dvd-s for partition management… Every attemp simply freeze machine.
Then I was try to install mac os (snow leopard) from install dvd and installation was done smooth without any problem… Really don’t know why I can install osx and can’t install or boot any type of windows cd/dvd.
After installing snow leopard I was try to make new partition and install windows trough apple bootcamp 3.0 but again same problem. When machine reset and try to boot from cd it simply freeze.

HP Pavilion 500-210 QE Can't boot from any hard drive.

Good Evening. As you can see from the subject, my computer just can't boot from any hard drive that I put on it. I tried swapping the power supply, the SATA cable, resetting the BIOS, enabling legacy boot, changing from AHCI to IDE and RAID...
When I get to the BIOS setup, I can see the hard drive and its specifications, but it just won't boot or show up when I'm trying to install a new OS. I'm not an expert, but I think the problem might be in the motherboard SATA ports, but I'm not sure. Just to make sure, I did try another hard drive and it didn't work aswell.
I was also thinking about buying an external hard drive and instaling my OS on that, but I don't even know if that's possible and I would really like to have my computer working again.
Thank you for your attention!

What is the installed operating system?
Did you make a recovery disk set?
Did you happen to make a Windows 8.1 startup disk or USB recovery thumbdrive?
Have you tested the hard disk?
Press the power button and then immediately tap the Esc key. In the Startup menu, choose F2 for Diagnostics. In the HP Basic System Diagnostics menu choose hard disk. Run the test and post the results here.
The issue you are facing has nothing to do with the SATA ports. It is a configuration issue. Your PC is a modern one and its BIOS (UEFI) is far more advanced than what you may have seen before.
If you want to install a different operating system then you will have to make a few changes in the BIOS configuration. Secure Boot is turned on by default for Windows 8 and Windows 8.1. If you try installing a different OS without turning this off then your system won't boot up. You may be running into this if you are trying to install another operating system.
The image below is what will be seen in the BIOS of your PC in the security tab --> . In the secure boot configuration options do not clear the secure boot keys! Those keys are your operating system license activation keys.

HT4848 My old Mac G5 displays "You need to restart your Mac" + gray screen. Won't boot from any disc, no safe start, did PRAM reset... nothing. HELP!

My old iMac G5 won't restart no matter what I try. I get "You must restart your mac" plus grey screen. I've reset PRAM, tried safe start, tried booting from original iMac discs.. all no good. This happened when I was deleting files in preparation for trading in at Best Buy. Anybody know what's going on?

If you are really running a an "old Mac G5", then you have posted in the wrong Forum.. You have posted in the "Intel iMac Forum" by mistake.

Can no longer boot into Mavericks 10.9.5

My problem is that I can no longer boot into Mavericks 10.9.5 on my mid-2012 Macbook Pro. The problem arose suddenly without any known major changes to my software or hardware. The booting process freezes with the apple visible and the circle below it spinning endlessly. Every several seconds, the display very briefly gets brighter, then the circle starts spinning again and the process repeats itself. It never gets to the user login screen.
Other than keeping various apps up to date, I don't recall any recent major operating system or other major software updates, nor have I made any recent hardware changes. I've searched a multitude of threads and and tried any number of fixes without success. Here's what I've tried so far (and probably a few more that I can't remember): (1) Repaired the startup disk with both Recovery HD -> Disk Utility and single-user mode -> /sbin/fsck -fy; (2) Repaired the startup disk permissions with Recovery HD -> Disk Utility; (3) Reloaded the Mavericks 10.9.5 operating system twice; (4) deleted /Library/Preferences/com.apple.loginwindow.plist; (5) reset PRAM and NVRAM; (6) booted with "D" pressed and ran the Apple hardware test, which ran for about 40 minutes and reported no problems; (7) tried booting from a bootable clone of Mavericks 10.9.5 on an external hard drive, which also failed at the same place with the apple showing and the circle below it spinning endlessly. ***Oddly, I am able to boot from a bootable clone of Mountain Lion on an external hard drive. It's Mavericks that won't boot.***
Here is the part of the system log the repeats itself over and over and seems to correlate with the repeated failed attempts to complete the booting process. Any help would be appreciated beyond words:

Hi
You got a prob I think, if you can boot a windows, MSconfig, startup options might restore the boot files.Only other thing is to try and either load a new windows and let it setup a boot file, or perhaps a win98 startup disk, and fdisk, then set active partiton, which will set an MBR. But that would leave a load of work to do, I think I'd opt for an install of XP, and let it repair existing installation, and make a new boot file.
Hope you don't need the info on disks. If you do, I would install another HDD, load XP, then copy original Disk to save place.
Good luck

Can no longer boot to MacOSX after bootcamp install

Hello all, I have an issue to where I can no longer boot into the Mac OSX partition after what appears to be a failed Windows bootcamp install. As I was running the bootcamp assistant process, a reboot occurred and I was greeted with the "No bootable device -- insert boot disk and press any key". I have no idea how to get past this and boot back to OSX.
Things I have tried:
Holding down the "option" key does nothing, even using a USB keyboard
Resetting PRAM (CMD + OPT + P + R) does nothing, even with USB keyboard
I have put in a MAC OSX 10.7 Disk and cannot boot to disk using CMD + C on startup
I also pulled the hard drive out and connected it to another PC and wiped the drive completely. I put it back in the macbook and I am still presented with this error. It seems, even though I get the Mac startup tone, that it is stuck in which ever OS it tried to run previously, that being Windows. Not sure why I am still receiving this error even after wiping the drive completely clean.
As far as hardware goes, I am pretty sure its a late 2010 Alumn. Macbook Pro. I cant get the current model number since I cant boot the OS. Any help is appreciated.

Please reset SMC as well.
You can get the serial number from the back cover and use https://selfsolve.apple.com/agreementWarrantyDynamic.do to find the model.

My trusty Mac LC no longer boots from the HD

I purchased a new Mac LC many years ago and it has served me well until recently when it would no longer boot from the hard drive. When I boot from a Disk Tools floppy, I get some limited success but do not ever hear the HD spin up. The startup chime also does not sound. When used as the boot disk and trying to use the installer option, the program can't find a SCSI drive, only the floppy drive. The 5V & 12V to the HD are right on and a new PRAM battery is installed. I can load and run programs using the floppy drive but that requires a lot of disk swapping. I tried substuting a tested Apple LC HD with the same results and now I suspect the problem is not the HD but is somewhere else. Any help would be gratefully appreciated. Thanks!

Thanks to Jan & Jeff for their quick response to my question. Here is some additional background information which may give you both some more ideas.
The original 40 MB HD was replaced with a 120 MB HD along with an increase in RAM to 4 MB sometime in the first year after I bought the LC. The 40 MB HD was installed in an APS (?) external SCSI box with its own power supply. OS 7 was just becoming available and Apple gave me a set of disks even though OS 6.x was in the computer so I put OS 7 on the external (40 MB) HD. Everything worked great for 20 years although there were periods of intermittent use when I used other computers for work, Internet, and e-mail. I powered up the external HD infrequently but it worked fine the last time I tried it some months back.
Then when I fired the LC up 6 or 7 weeks ago, it would not boot unless I turned the power switch on & off 2 or 3 times in succession then everything functioned normally. Then it would not boot at all even from the external HD.
Now, to address some of your comments and observations:
All connectors, plugs, SIMMs, and socketed RAM devices were removed, examined and replaced. All electrolytic caps showed no signs of leakage or swelling and the PWB looked in its original condition.
The +5, -5 and +12 voltages measured at the power supply connector were within 1%. When I originally thought I had a HD problem, I opened up the 120 MB HD and when trying to boot, the platter would give a slight twitch with no tendency to spin. A friend of a friend (a MAC serviceman) brought a couple of vintage drives SCSI over to try with similar results. The Apple HD I purchased was tested and guaranteed, although wiped clean. It has since been returned. As I said in my original question, the Installer on the floppy could not find a SCSI drive. In all of my efforts I could never get any of the hard drives to spin up.
Although I have a MacMini (OS 10.6.8), I still used the LC because for drawing schematics and floor plans, printing labels, etc., simple is better for me. Is there any hope that I can get my LC working again?
Many thanks for your help and suggestions. len-35

G4 PowerMac no longer boots from External FireWire Hard Drive

What would cause a G4 PM to no longer boot from an Ext. FW HD that was working fine yesterday and in fact still mounts fine on the desktop..... but when I go into system pref's and attempt to select the ext. HD (and it does show up as an option to boot from since it has an OS in Mac OS Extended Format, Journaled) but after selecting said drive the system simply defaults to the main HD instead and not the external HD I selected within system pref's.???
(I've run apple's disc utilities / First Aid ..... it simply says no repairs were necessary).
The HD in question is a Maxtor 120GB 7200 ATA133 in the following ADS enclosure:

Same enclosure works fine with a pionner 110D S-Drive.
Any Suggestions (short of installing the Maxtor hard drive internally which I may have to try anyway)?

MacPro won't boot from any disk but the original

We picked up a lightly used MacPro 2 x3.2G Quad Intel Xeon at work. The plan was to remove the internal drive (which is also the boot disk) and replace it with a brand new WD Caviar Black 500G drive with OS 10.5 freshly installed, and then use Migration Assistant to transfer from the old machine.
The problem is that when trying to run the OSX install disc on this new machine, it will restart, but then not boot from the install disc. Rather, the apple logo pops up, it thinks for a bit, then the grey curtain drops and i get the multi-language "you must restart your machine" message.
So, after successfully doing an install of the OS on the fresh drive using a different machine, i put it back into the new one, restarted holding OPT, and selected the fresh OS drive. I get the same multi-language message, and the machine will not boot. I've tried installing the OS on a different HD as well, to the same results.
The new machine will restart using the startup disk (internal HD) that came with it and will run Apps, etc. To confuse things further, i pulled my startup HD out of my personal tower at home (also running OS 10.5, but it's been updated to 10.5.8), stuck it in the new machine, and tried to reboot from that. This DID work (normal time startup, apps work, etc).
I thought this might be a HD problem, but now it seems like a machine problem. Maybe it doesn't like the OS install? I dunno.. Thoughts?
I just had one. I'll try to clone my HD/OS from my personal computer to the new WD 500G drive, and if that works, i'll just go from there...maybe i just had to type this out to think of something different to try, but i'll post it anyways...

So you're saying essentially that this new machine, when it came out of the Apple factory, had OS 10.5.x installed on it, and because that was the original install, it won't recognize something that has OS 10.5.0, even if that install is on a fresh HD? Basically the hardware inside the tower can't/won't recognize any OS prior to the original 10.5.x factory install?
well, if that's the case, then 1)that's ridiculous of Apple to do, and 2)it makes this whole problem make more sense, and it's good future knowledge for me to have.
I cloned my personal OS (but not the users, docs, etc) and stuck that in the new tower, and it works well so far. I'm in the process of copying files to other internal drives, and i'll be using Migration Assistant to transfer users from our old system to the new one, and if all still works fine after that, i think we'll be good to go. So, based on what you've told me about the factory OS install, etc, i think we're on the right track.
Thanks very much for your input!
