Mac Pro not booting from CD's using 'C'

All of a sudden I am unable to boot from a CD. Every disk that I try will not boot. The CD drive will try to read for 5 minutes, then crash with that different language please restart your computer crash screen. I've tried DISKWARRIOR and MacOS X Leopard. They will not boot. I've cleaned the disks and reset the PRAM, but still won't work. All external connections are unplugged.
3 months ago, it was working perfectly, I even did a clean install of Leopard. The only thing that was changed in my system, was an upgrade to the NVIDIA GeForce 88GT, but why would using a different video card force a crash during a CD boot?
Otherwise, my MacPro is working perfectly and the disk has no errors. I can read, write, install apps and run movies on the CD ROM drives. but cannot boot

Recently, I bought diskwarrior but it doesn't boot. I tried the Leopard install to test it out. That doesn't work, then I called Alsof and they said it should boot on my current system.
DiskWarrior will not boot on a Mac Pro (Early 2008).
"All Mac models meeting the system requirements for DiskWarrior *except the new Mac Pro and Xserve models introduced on 01/08/2008, the MacBook Air introduced on 01/15/2008, the MacBook/MacBook Pro models introduced on 02/26/2008 and the iMac models introduced on 04/28/2008* can be started from the CD."
<http://www.alsoft.com/DiskWarrior/support.html>
If you want to use DiskWarrior, you need to put it on another drive or partition containing OSX 10.5.4
Therefore, all of sudden nothing boots. Like I said, the only change I did was to replace the video card.
That's why the Leopard DVD won't boot. The Leopard DVD that came with the computer doesn't have drivers for the new graphics card. If you still have the old card, install it, install Leopard, update to 10.5.4, then put in the new graphics card.

Mac Pro not booting from disc

Hey folks,
I've got a Mac Pro and I've installed a clean HDD and I plan on installing OSX Snow Leapord (SL). When I insert the SL dvd, the mac stays stuck on the screen with the apple logo? Any ideas on how to get past this?

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:

Mac will not boot from hard drive or install disc

Hello All
In dire need of advise...my intel Mac will not boot, even tried booting to the Snow Leopard install disc and all I'm getting is the white screen, apple logo and the wheel.
Just before this happened there was a buzzing sound like the fan was about to fail but that is only a guess on my part. Is there a keyboard shortcut to boot to a terminal window or similar to force the computer to boot from the install disc.
Thanks in advance for any help offered.
Warren

Hi Warren
Try holding the Option key and see if it will boot into Startup Manager, where you should be able to choose from a good Drive or your install Disk.

or the D key and run the Apple Hardware Test.

Also note: key commands may require a USB Keyboard if your using a wireless and it has become unpaired.

[URGENT] Mac Pro not booting, Fan error but fans are working.

Hello,
My server G5 is stuck on grey screen with spinning wheel. I ran the AHT and got the following:
2FAN/4/8: CPU A INTAKE
All the fans are spinning. I would really really appreciate if I can get any help or advice. I tried searching for this AHT error but could not find anything solid.
This is our main server and its crucial to our organization and I am sweating bullets here.
I reseted memory and unplugged all RAID drives. The three LED on the Logic board are Red, Yellow and Green; Power On, Trickle and Open Firmware respectively.
Thanks for any help.

Just to say that usually it helps to include the make/model of RAID controllers, whether it is hardware RAID or not. The Mac Pro Apple RAID card IS a PITA and is particular sometimes about drives and its battery reconditioning as well as mounting drives and time to create a hardware RAID5.
When a drive causes trouble it is often though not always because of directory being damaged and OS X can't even inspect to see if there is a system or if it can be mounted.
And because the G5 normally only has two SATA drives, to use three requires a bracket or something else to add drives, like Sonnet G5 Jive. And then a PCI SATA controller with internal ports. But that is just your average SATA controller.
If it was a Mac Pro the thread could and should have been moved to another forum. And you still refer to this as a Mac Pro, not PowerMac. Which leads me to wonder.
Molex y-splitters as needed in a G5 but three yrs for a set of drives, I'd say they were due for backup + erase/initialize and restore. Hopefully you kept them in shape with Disk Warrior during that time (don't rely on just Apple First Aid to maintain and repair/rebuild directories).

Mac Pro not booting after restore.

Hi. Hopefully someone can help me here.
Tried a total system restore from my leapard Install disk to a recent time machine backup of Snow Leopard 6.4 after a mishap with Mac Keeper (easily done I tell you)
The drive seemed slow and unresponsive even before this and had initially spat out my two Snow Leopard install disks but I managed to boot from previous original Leopard disk after I shut the machine down for a while. Using utilities, I found the back-up required and started restoring some 435gigs worth which took 18 hours. At times the drive seemed to go to sleep. I was beginning to think that the drive was just about hanging in there with the odd behaviour that had recently happened. I had initially thought the disks must have been scratched but it was stating it could not read other disks too so I guess there is a definite drive problem going on.
Anyway, eventually the next day my sceen stated that the mac was restored. Tried to boot. Gray sceen of death. Telling me to shut down and reboot. Happened every time. Tried starting command +S.where it's stating "Mac OS not yet set". It wont let me type anything. Tried rebooting from leopard again to see what disk utility was finding. All seemed OK. The computer is seeing the drives and the content amounts. Tries varifying/repairing disks. all OK. Tried repairing permissions on sysem drive which finished in a split second. I'm thinking of changing the superdrive and backing up again but this may not be the problem at all. I did have a file that said previous system on the Mac for some reason separate to the system it was using. Could that be a problem here. Any help greatly appreciated. Thanks James
Mac Pro - Snow Leopard 10.6.4 (2006-2008)

Hi
Thanks for replying.
Yes I booted from Leopard install disk as the dvd drive wasn't seeing either of my Snow Leopard ones.
From utilities menu I restored a time machine backup that I had done just before using Mac Keeper. This was meant to be a complete system install as I didn't know what files Mac keeper had moved. Though it took a long time, it finally stated that it was restored and I thought I was back in business. However gray screen shut down after a few 3 seconds of Apple appearing everytime.
The DVD drive is not letting me boot on leopard install everytime either. Any thoughts

Updates on Mac Pro Prevent Boot from SSD

Hey there everyone,
I recently upgraded my 2010 Mac Pro (Quad Core) to an SSD Drive using the OCZ Petrol Drive and I coudn't be happier. The system is super snappy and works great. That said, I downloaded the latest updates to my system last night and as of today, it wont boot to the SSD. All other boot operations seem fine, but the SSD wont boot. It goes into the progress bar screen you get when a firmware update is running then just shuts itself down.
I tried reseting the PRAM with no luck and also tried a disk repair from the Lion Recovery Partition as well as a Lion DVD I made, but both fail to repair the disk. I am currently recovering from a Time Machine backup and everything seems to be OK so far, but has this happened to anyone else with the latest batch of updates? I will update this post when the Time Machine Backup completes and let you all know the outcome.

Update 2: I did a hard shutdown and rebooted holding down the option key to try and boot from the Lion Recovery partition and perform a disk repair only to find out the Lion Recovery partition was no more. Wow...looks like this is a bigger issue than I thought. Reinstalling Lion from a DVD now. This should be fun...

Mac pro not booting up

Help my mac pro will not boot up gray screen with apple logo and the loading icon keeps going round and round but nothing else happening. Iam running Lion OS X (10.7) Help please

hello,
I've a 2.66 MAC PRO, with Tiger OS (10.4.10). I've same problem denounced by clarky99. Everything started a month ago, after some updates:
- plug in manager
- Java
- utility airport
- IDVD
- Airport extreme 2008-002
- security update 2008-007
I've tried the following:
- MAC OS hardware test: no problems
- fresh installation of the OS on an external HD: no change
- PRAM reset: no change
- removal of the physical RAM cards: no change
The only way to avoid the startup and video problems is starting in SAFE MODE (pressing shift key during the boot).
This make me think it's an hardware problem, but I'm not shure.
Next attempts:
- try another video card
- (time consuming) disabling all the processes which are not activated in SAFE MODE, but are started in the normal statup procedure, and then by re-enabling one by one
Any further suggestion is welcome!

Printer shared from my Mac is not seen from a PC using Bonjour for Windows

I am going nuts here, hope someone can help.
I have a Canon multi-function printer (MP830) attached via USB to a Mac G4 (with Mac OS X Tiger). At one time, I had it set so a Windows 2000 PC could print to it but deinstalled it after some printing issues, and have been unable to get to working again. The machines are connected together via a Netgear router. As far as I know, everything is the same as it was before, yet I cannot get it to work as it did.
- The printer works fine from the Mac.
- If I connect the printer to the PC, it works fine.
- On the PC, using Bonjour for Windows, I cannot see the printer attached to the Mac but I can see, and print to, an Epson printer that is attached to a different Mac.
- And from the second Mac, I am able to see -- but not successfully print to -- the Canon printer. The print job stays in the queue of the second Mac and says "Unable to connect to SAMBA host, will retry... Error: Connection failed with error."
- I have tried:
-- de-installing and re-installing Bonjour for Windows and the Canon print drivers on the PC
-- and have de-installed and re-installed the Canon drivers on the Mac
-- I have removed and re-added the Canon printer on the Mac. Printer Sharing is on, and this printer is checked in the Sharing box.
Any suggestions?
G4 Quicksilver and Dell PC with Windows 2000 Mac OS X (10.4.9) Canon MP830

Thank you. Those are beautifully written procedures.
Looks like it's a network issue. I reach the step, "Adding a printer using the wizard":
You must enter the following URL, you must use the Queue Name you noted down earlier
http://<IP address of Mac>:631/printers/Queue Name
which I do, entering
http://192.168.0.4:631/printers/MP830
and I get the following error:
"Could not connect to the printer. You either entered a printer name that was incorrect or the specified printer is no longer connected to the server."
And then I am toast!
Using the other procedure, I simply don't see the Mac's printers in the Bonjour Wizard's "Browse for Bonjour Printers" window.
Not sure where to go from here -- any ideas?
The Mac's IP (set via DHCP) is 192.168.0.4, subnet mask 255.255.255.0. The PC is 192.168.0.5, I can't find the subnet mask.
Pretty sure it's a network config issue, especially isnce I can Bonjour to my other Mac.
TIA...

MacBook Pro not booting from CCC clone from earlier MacBook

Hey, all
A bit convoluted, but here's the deal.
My wife bought a MacBook (back in 2009, the aluminum model WITHOUT firewire). She got a new job that gave her a MBP that she can take home and do with as she pleases. We decided to clone her MacBook's drive (was, at the time, running 10.5.7) to an external drive (USB 2) and wipe the MacBook to give to her folks as a gift.
Long short, her MBP wouldn't boot to the external drive; my MacBook (same model as the one we cloned) did it just fine. I figured since her new MBP came with Snow Leopard, I should upgrade the cloned OS so the BIOSes would match up. I upgraded the cloned OS to the current version of 10.6, still no luck. Again, it still boots up on my MacBook just fine, but not my wife's MBP. I even created a partition on her internal drive and recloned the drive to it; I still get the same thing: chime, grey apple on white background...hang. It never progresses beyond that, and it just sits like that for hours until I reboot to her "work" drive.
I'm kind of at a loss, and don't really know how to fix this; I was hoping to make this easy for my wife so she can have her work and personal computers on different partitions of the same internal drive.
Any suggestions? The MBP is 3 months old, but was factory new. The MacBook is a mid-2009 model, aluminum, user-replaceable battery, no firewire.
Any help would rule. Thanks!

update:

why would i be able to install my orginal os but not my new one

Mac Pro will not boot from Leopard or any CD or DVD install disk

My Mac Pro wont boot from my Leopard install DVD. It never gets by the gray screen, then after several minutes the screen scrolls down black and says I need to restart my computer. I tried my Tiger install disk and it still wont boot from that DVD. Held down the "C", used "option" and selected DVD and still no boot. I can boot from one HD that has Leopard 10.5.8, but another HD with Snow Leopard 10.6.3 will not boot. The HD with Snow Leopard shows up as "EFI Boot" not the name I gave that HD when I startup using the "option" key. Any help would be appreciated.

At first I was just going to say it sounds like you have a bad optical drive, but then you had to go and say that it also won't boot from a HDD.
That just makes things a whole lot worse.
Start by removing the side cover and checking the RAM to see if any of the LEDs are lit up indicating bad RAM. Usually if there's any bad RAM found, it will just automatically disable that stick, but maybe yours isn't for some reason.
Look for any other LEDs that may be lit. Generally speaking, the only time you should see an LED (outside of the power LED) lit consistently is if there's a problem.
You should also see if you can get Apple Hardware Test to run, which may or may not find some problem.
But sorry to say, it's sounding very suspiciously like a bad logic board.
One other thing to try, is putting the SL drive into a different slot. So if you were putting it in slot 2, try slot 3 or 4. If you just have a bad SATA port, you might be able to just work around that until you get a new system.
If by chance this system is still under warranty, do not walk, do not pass go, do not collect $200, RUN to the nearest AASP or Apple store to make it THEIR problem to sort out.

HT4818 Boot from laptop's Windows Hard Drive in Mac Pro via Boot Camp

I have a work laptop that is on Windows 7. It's a work hard drive so I don't want to mess with it (particularly as it's encrypted). I basically want to use it on my Mac Pro rather than my piece of junk standard issue laptop when I'm working from home.
What I would like to do is pull the drive out, put it in my Mac Pro and boot from it using Boot Camp. Guidance I've seen so far talks about not being able to use an external drive but having to partition an internal drive. However, if I've got everything on a separate drive (i.e. my laptop's drive), will this work?
Thanks!

Thanks for the quick (and no nonsense) response!

Emac Will Not Boot From CD

Hi - any help will be greatly appreciated.
I have an eMac G4. My wife was using it when the dreaded spinning ball appeared. She did not know about the force quit procedure and turned the machine off. On reboot the Mac returns almost to where she left it - Question mark > changes to Smiley Mac - spinning ball upper left - clicking noise very faint in Back. CD heard spinning but when holding "C" key will not boot from CD. Using start > Option, CD appears but right arrow returns screen to smiley and spinning ball upper left.
Any idea if she could have mechanically hurt HD when shutting down as ball spun? Why wont the eMac boot up from a bootable CD when holding "C" or option?
Thanks
John B.

Thanks Tom
I've experimented. Reset the PRAM ... reset the PMU. Now I am getting a little different result. The Mac musical sound when booting works (didn't before), but same result.
Interesting notes: The computer does not shut down when shut down using the power key. It is actually in 'sleep' mode because touching any key or moving mouse wakes it up and begins the start-up process.
I attached an external HD with a boot-up disk on it to the eMac and held down 'option' on start-up. Got the correct screen with the OSX CD in tray and HD 120 showing as options. Chose HD, clicked right arrow and got a long kernel panic notice. On re-doing the same, HD did not show at all. OSX CD in tray showed as option but would not highlight. Then I hit return and got a message saying "invalid memory access" with several numbers. Could the memory be corrupted? Bad Ram chip? Should I remove one ram chip and try that?
Thanks for Help.
John

Mid-2009 MacBook Pro sees internal SATA hard drive, but will not boot from or format

I inherited a Mid-2009 MacBook Pro (15-inch, 2.53 GHz model) with a very strange issue.
It first presented itself as not being able to boot from the internal SATA hard drive that came with the computer. Nothing I tried could get it to boot, so I assumed the file system was corrupted beyond repair and booted from a CD to try to format the drive. Disk Utility on the CD would not format the drive, giving me strange error messages like "Unable to write to the last block of the device".
At this point I figured the drive itself must be toast, so I pulled it out and put another known-good SATA hard drive in, booted from CD, and attempted to format. Again, same error messages and an unsuccesful format.
So I had the bright idea of formatting one of the drives in an external enclosure and then putting it in the MBP to see if OS X would even install. No dice. Get a cryptic error message before installation even begins.
So I installed OS X on the drive in the external enclosure and put it in the MBP, and it attempts to boot, but never goes anywhere.
So to sum up, the symptoms I'm seeing:
MacBook Pro CAN see internal SATA hard drives.
MacBook Pro WILL NOT boot from any internal SATA hard drive and cannot format or install OS X to any internal SATA hard drive.
MacBook Pro WILL boot from any CD or external device and seems to work properly otherwise.
At this point I'm thinking it's one of two things: the hard drive ribbon cable or the SATA controller on the logic board.
Since the MacBook Pro seems to work completely fine other than this one issue, and will boot properly from both external devices and the CD (also a SATA device), I'm thinking and hoping that it's just the hard drive ribbon cable. From my searches online, I've heard that this batch of MacBook Pros is known to have issues with the hard drive ribbon cable, but it seems in most cases this manifests itself by the Mac not being able to see a drive at all.
I've done quite a bit of troubleshooting to get to this point, but right now I'm just looking for any feedback at all. Specifically I'd love to know a way I can easily test to see whether it's the logic board or the cable.

UPDATE: An interesting development!
I just tried a third known-good SATA hard drive, one which I believe supports SATA I only (but I'm not sure), and unlike the other drives that the Mac sees but cannot properly interact with, the Mac can't even see this one when I put it inside.
Frustrating as this may be, I believe I'm actually getting closer to a solution since my symptoms now appear to be closely aligned with people having SATA ribbon cable issues.
Onward!
