MacPro can't boot from external drive

Running 10.7.3 and a MacPro which gets backed up each night with SuperDuper. Can't boot from this drive (black screen). Yet I can take the same drive and start up my Macbook Pro! So it isn't the drive or the data on it. I'm stumped. Could this be related to an issue where I can't get this same MacPro or system to successfully backup to Time Machine without error? The boot drive seems OK (ran Disk Warrior and Disk Utility).

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
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(s)?
After testing, reboot as usual (i.e., not in safe mode.)

How can I boot from Clone Drive?

I believe that I am having some problems with my boot drive, and I would like to boot up my system using the boot drive I created with Carbon Copy Cloner, which is on another internal HDD within my tower. I would like to boot with that cloned copy, but have forgotten how to do it. My boot drive is a SSD drive, and appears to be working well, but disk permissions showed many errors, most of which I was able to repair with repair disk permissions, but not all of them. Any help and/or direction is greatly appreciated.

System Preferences > Startup Disk ...
... will show all Volumes it thinks it can boot from. Set to whichever one you want.
That presumes your Mac is booted up and System preferences is working.
If not, hold down the Option key at Startup.
You get a display of all bootable Volumes, and the Eject key is "live" once they are all drawn.

Can't boot from clone drive

After getting a blank gray screen on startup, I determined it was time to replace my hard drive. In preparation for installing a new hard drive, I used CCC to create a clone on an external hard drive. However, it appears I cannot boot from the external drive when I start in recovery mode - I still get nothing but the gray screen. I can still do a soft boot of the original hard drive, but I can't confirm that the cloning worked. Is it possibly something other than the HD?

Then boot from the Recovery HD on the external drive after you have installed the new drive in the computer.
Install Lion/Mountain Lion on a New HDD/SDD
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-R keys until the Utilities main menu appears on the screen.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your new internal hard 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.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Help! I Can't Boot from Firewire Drive (Previous MBP C2D Hard Drive)

Can a hardrive from a C2D Macbook Pro start an i7 Quad MBP?
I just sold my 2008 15" 2.4ghz C2D MBP, (that had 10.6.5 installed), and today bought the newest
17" 2.2ghz i7 Quad Core MBP, (that has 10.6.6 pre-installed.)
I installed a fresh HD on the 15" before selling it, and kept its HD, and put it into a FW800 enclosure.
+(note: The 15" Macbook Pro I just sold, booted fine from this HD in the FW800 enclosure.)+
Before migrating my data, from the FW800 drive, I figured I would upgrade the old OS to 10.6.6, so it would be a seamless migration.
While up and running on the brand new i7, I could see the FW800 drive with 10.6.5 as a Startup Disk option in System Preferences.
I rebooted holding down the option key, selected the FW drive, and pressed the arrow below to continue startup.
The grey screen with the apple came up immediately, but I was horrified that the spinning gear never did appear, and startup froze at that point. I left it like this for five minutes. Grey screen with apple. Frozen.
So, I held down the power key, shut it down, then restarted holding down Command-S to run Disk Utility in SIngle User Mode, (/sbin/fsck -fy). Disk was okay.
I rebooted into the new internal, installed Diskwarrior 4.3, and checked the FW800, and it had no errors.
I opened Startup Disk in System Preferences, and chose the FW800 drive as the Startup Disk, and rebooted. Same result. Grey screen with apple, and no further...
Can someone please help me troubleshoot this?
Should I be able to boot this new MBP i7 with the HD from my old MBP C2D?
Is there something incompatible between the old C2D and i7?
Thanks in advance!

That CD2 OS will not boot into a new computer's OS.
Hi, thanks for replying.
I knew that the switch to Intel from ppc, meant a ppc drive, partitioned with APM could not boot an intel machine with a GUID partition table.
Do you know:
1. for certain that a C2D HD cannot boot an i7 machine?
2. and why?

Why not use Migration Assistant in the Utilities folder?
I am planning on doing this.
My old drive was 10.6.5.
The new machine has 10.6.6 pre-installed.
I figured that if I was able to upgrade the old drive to the same OSX first, it would provide a more seamless migration.
I was also concerned that my applications on 10.6.5 might become broken if they were migrated to 10.6.6. I really do not want to have to install everything.

How can I boot from USB drive?

I have installed a Kingston SSD drive on my Macbook Pro. The original HDD is now in a USB enclosure. I tried to boot from the supplied CD by selecting it in the preferences. However they supplied a CD with Aarons for Windows. Now I cannot either clone my HDD to the SSD or boot from the original HDD. How can I override the CD as boot disk?

Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"OPTION" key.
3. Release the key when the boot manager appears.
4. Select the disk icon of the external USB drive.
5. Click on the arrow button below the icon.

Can't Boot From External Drive

Situation:
Prior to upgrading to Lion I used SuperDuper to create a copy of the existing internal hard drive on an new external drive (iOmega eGo 500GB).
Tested booting from the external disk and it appeared to work correctly.
Upgraded to Lion.
Several days later attempted to boot from the external disk (by setting the start up disk in the system preferenes ) but it fails.
The system always boots into Lion.
What I've tried:
Setting the start up disk through system preferences
Holding down the option key to select a disk on startup - interestingly enough I only see the internal hard disk and a recover HD. No sign of my external disk.
Using a clean partition on the external hard drive I installed SL from the retail DVD. This produces the same effect of system booting to Lion on the internal drive, which suggests that the problem is not related to the copy I made using SuperDuper, but rather has to do with the external drive or something in Lion that prevents using an external drive (but I've never heard of such a thing).
Talked to technical support at Apple since I had newly purchased Lion. They couldn't offer a solution but did give a lot of thought and suggestions - but they don't support booting from an external disk.
Talked to iOmega technical support. Not helpful but did figure out at the end of an online chat that they don't support their disks being used for external booting.
Emailed SuperDuper. Very helpful. They offered some suggestions but in the end these didn't work.
Characteristics
Lion 10.7.4
iMac 2007
External Drive Interface FW800
I'd appreciate any suggestions as to the cause of the problem and possible fixes.
Thanks

@shootist007
Still no success but more information:
I found the USB cable for the drive, connected it to a powered USB hub (note that there are two cables going into the hub that must merge and go into a single connector for the USB interface on the drive). with both cables plugged in I still can't get the external drive to boot.
I need to do one more experiment on this. The hub is fully loaded so I'll try removing as much load as possible on the USB to see if I can get it to work.
Regarding your question, there is no way to get power to the drive. (Now I think about it, the design is for a portable drive that you can carry around with you so iOmega aimed the design at not needing a power supply to make it very portable). Hmmm, didn't think about that when I purchased it.
If reducing the load on the hub doesn't make it work then I'l have to get a replacement drive with its own power supply.
Thanks for your help. Even though no success yet I suspect you've identified the problem.

Can not boot from Hard Drive and or CD

Hi
I have a SUN Blade 1000. I loaded Solaris 10 a few days ago
and had it running pretty good until I ran an update program.
Now I cannot boot the dam thing. IT just hangs at a * prompt somwhere in the boot process.
I would like to re load Saolaris 10 but do not have a clue how to
make the machine boot from the CDROM if I cannot get to the OK prompt and I cannot get to ANY prompt that will let me get ANYwhere for that mater.
Is there some key or combination of keys I could push or something to get this dam thing to boot from the CDROM so I can start over???
Thank you in advance.
I have almost no experiance with SUN Solaris on SPARC or any other platform.
I know Windows and x86 hardware very well and have built many machines.
Is there a way to get into the Bios at boot time like with an x86 system? The last question is not as important as the first one of how do I boot this pig from the CD.
Thanks
Jim

How did you begin the previous installation?
Have you spent any time reading these forums?

Can't boot from firewire drive

Howzit,
I have partitioned an OWC Mercury Elite-AL Pro 1.5 TB firewire drive into 2 partitions using Disk Utility and GUID mapping. I then used Carbon Copy Clone to clone the startup disk of my MacPro, which runs OS 10.4.11. The clone successfully boots when it is connected to the MacPro.
The problem is that I am unable to boot from the firewire drive when I hook it up to my iMac. When I restart and hold the OPTION key, the clone appears as a startup option, but the computer freezes when I click on it. The clone also shows up as an option in the Startup Disk preference, but when I try restarting after selecting the clone, it freezes the same way: gray screen, no apple, no rotating gear.
Can you help?

Make an OS partition then for each. Or, upgrade your Mac Pro to SL as well. Unless there is software holding you to Tiger.
Now, when SL came out, I know I saw a lot of threads regarding issues booting from external firewire drives, so you may not be 100% out of the woods, but you should.
I'd expect to get a panic screen from 10.4, lacks any support for newer hardware / graphics card and more.

Can't boot from external drive, no options...

Okay so I just upgraded my 24" iMac to Snow Leopard, from an external drive, and things seemed fine. I was migrating my old settings and then after I noticed I couldn't access system folders. It wanted old settings' permissions, not the new one, so I right-clicked on the folder and set permissions so that anybody could write to it.
Still didn't work. I thought I should then reboot.
So I did. But now when I try to log on, to my old profile or my new one, neither password works. Even though they're the same. If I get it wrong enough times, it will let me put in the master password for the computer, in a separate pop-up, which is the same, and that works.
Then it wants me to give a new password, back in the old password box, and then it just shakes angrily afterward, not accepting anything I type. Why is this?
The next step seemed to be re-install Snow Leopard. But pressing the option key at startup doesn't let me boot up from the external drive. I looked online with my macbook and found all these other boot options, but none of them work. Not a single one has any effect.
One thing I should mention is that I'm not using the standard iMac keyboard, not sure if that makes a difference. It's a PC keyboard and the keys are just slightly rearranged but it has Alt, Ctrl, and the option key is a circle with the windows logo in it. Any chance that the new OS isn't recognizing the new keyboard properly?
I just don't know what else it could be. Any help is appreciated.

I only have one master computer password, and it's not the same as any of my other passes. That's the pass that's needed to log on, and access system info. However it's also the same password as my old profile, that I was migrating over (which is still confusing as to how to do a clean install and then bring old admin info over so they work together seemlessly) so now when trying to log on, after the first reboot, I saw that I could log on to the old or the new profile. As well as a guest account, which isn't accessible though.
It sounds like here you are talking about an admin user account & its login password rather than a "master" password. Only admin users can access & change system info (more or less). However, you cannot merge two user accounts, if that is what you mean by 'bringing old admin info over so they work together seemlessly.' Also, keep in mind that each user is a separate entity as far as the computer is concerned, whether or not they have the same login password, & that you can log into & use only one account at a time. So for instance, if you have a user account "A" created on the Mac & an imported/migrated account "B" from another Mac, if you are logged in as "A" you will not be able to access info in the folders belonging to "B" unless while logged in as "B" you previously explicitly set permissions on those folders for "A" to access them.
So whichever profile I attempt to log onto, when I type in the password, (there's even an obvious clue after a few tries, so no chance I'm getting it wrong) the box shakes like I got it wrong.
The box shakes only if you did get it wrong, so I don't understand what you mean about there being no chance that you got it wrong.
After like six tries, it asks me for a "Master Password" "Type the master password to reset this uer's password" into which I put my regular login pass that I've been trying over and over, and here it does work.
"If you change the password for this user account, you will create a new keychain to store the user's passwords"
So then it asks me to put in a new password, and verify it, but after each try it just shakes. It won't accept anything.
Again, I don't understand what you mean in the first paragraph above when you say "here it does work." The Master Password the dialog box asks for is one you would have had to previously explicitly set up for the computer in the File Vault tab of the Security System Preference. It is not associated with any user account (& again, it makes no difference if you set it to the same one as for one or more user accounts). It's purpose is as a "safety net" to unlock File Vault protected user accounts. As explained in Mac OS X 10.6 Help: If you forget your password for your FileVault-protected account, you must first fail to enter the account's password correctly three (not six) times, then click the “Forgot Password” button to get to the Master Password dialog box. Entering the previously set up Master Password allows you to set & verify a new password for that account.
If you can get this far, it means you are successfully entering the Master Password & have successfully reset the account's password to something new. If the box shakes after you then try to log into that account, it means you have not entered the same characters at the login screen as you did when resetting the account password.
If you mean something else is happening please explain it more clearly, in step-by-step fashion including the results of each step. Don't say things like "try it." Instead, say that you clicked on the "OK" (or whatever named) button & say what the result was.

Downgrading from Mavericks to Snow Leopard, can't boot from USB drive

I'm attempting to do a clean install of Snow Leopard on a 2010 Macbook. The MB had recently been upgraded to Mavericks, but because it was running slowly, I decided to downgrade. (If you respond to this post, please don't ask me why I'd make this decision.)
As with any other clean install I've done--all pre-Mountain Lion--I backed everything up, I created a .dmg file of the Snow Leopard, and made a perfectly good, bootable USB drive with the OS (1 partition, GUID table); I tested this USB drive on another Macbook, one currently running Snow Leopard, by holding option as I booted up. It works fine and gets to the installation screen.
I booted the Mavericks Macbook while holding command+r, and I erased the main HD. I then formatted it with 1 partition, with a GUID table. All was normal.
But here's where the problem starts. I plugged the USB drive into the formerly Mavericks computer, and held option for the bootloader. It recognizes the OS. But when I click the arrow to proceed, it inevitably has a kernel panic and tells me to restart the computer.
I re-made my bootable drive, and I tested it again on the other machine. Again, it's still fine. Plugged it into my main machine--again, a panic.
Using command+r to reach disk utility, I've now erased and repartitioned the computer's hard drive several times, even using the advanced-security erase feature. Still, the panic.
When I hold command+r at boot, it always forces me through the Internet Recovery. The only option offered to reinstall OS X is with Lion, which I didn't buy with my Apple ID.
What can I do?

Sorry, but this didn't help me. From what I gather, Mavericks (or maybe Mountain Lion) included a firmware update that, for some reason, prevents users from downgrading to anything before Lion. This makes things difficult, because I didn't buy Lion--I made the leap from SL to Mavericks.
Here's the strange part, I learned: When I enter Internet Recovery, I'm prompted to reinstall Lion, not Mavericks. And because I didn't buy Lion, my Apple ID/password, which are asked for, don't help.
Anyone else with suggestions? None of my USB-based installations are working, and I'm feeling out of luck. I don't want to spend money at the Apple store...

Can I boot from a SATA drive? What if it's RAID?

I'm planning on getting the MSI 875P Neo FIS2R 800FSB motherboard. I'm also planning on getting ONE SATA hard drive. Can I boot from the SATA drive? Do I HAVE to set up it as a RAID drive? Can you boot from RAID drives? RAID and SATA confuse me a little. Anyone care to help?

I'm using the MSI 865PE Neo2 board and I'm having this problem. It probably has an easy solution, but this is my first build, so I'm not sure exactly what to do.
MSI 865PE Neo 2 Mobo
2.4b P4
Seagate SATA 80GB HDD
Panasonic FDD
Lite-On DVDROM
It took me a little bit of experimenting, but I got the BIOS to recogonize the DVD & HDD. It seems every time I got it to recognize one, the other disappeared. Anyway, like I said, BIOS recognizes all 3 now.
I go to install XP and it says I need to install the drivers from a floppy (after I had previously hit F6). Well, where do I get the drivers? I have a CDROM that came with the mobo but I don't know where to find the drivers for the SATA controller on it. ???
Can someone help me by directing me to a download and/or the file names that I need to transfer to floppy for Win XP installation? I would appreciate it. Thanks.

New HDD + can't boot from anywhere, just Hard Drive

HI I have a HP Pavilion dv6700 laptop with Windows Vista 32-Bit OS.
I installed a new harddrive and ordered the original recovery dvds from the hp website for that model, but I can't get it to boot from anything but hdd, even if i change the booting order in bios and I also tried F8 but it only gives me one option to boot from hdd. I even tried a usb external cd drive., nothing works. How do I get the recovery installed on my laptop? Please help.

Maybe reseat your ODD , also if you disconnect the HDD temporarily can u boot to ODD?
I am an HP employee.

MacBook can't boot from HDD

Hello friends!
Please help me with my macbook late 2009.
I was a problem with SMC conntroller and take mac to service. After one week i took it and all looks good, working for few days without any issues. Today, after 2 hours of use my mac is hung and i use hard reset to reboot it. After reboot, gray screen appears without any action. I tried to reboot it again and again and after 5-10 attempts I see all my disk partitions with recovery mode and tried to start DISK UTILITY to test hdd. Disk utility also hung on scanning disks. I have no luck to tried start it again - always gray screen, question folder or O with /. I tested old hdd with other mac and it's worked fine, I tried to use another, new 1Tb WD HDD 2.5 - connected it and try to power on with recovery flash drive. Mac started without issues and I can boot from flash drive, started disk utility but mac can't find new HDD at all. Please note - I use a lot of methods, tried to reset SMC / PRAM/VRAM without luck. Safe mode also not helped, verbose mode show me "Still waiting root device" error for old HDD, but sometimes mac show all my old disk partitions - after I chose Macintosh HD - I see O with / and that's all.
Please help me to figure out issue. I think this not a HW issue... but why mac not show new HDD? Really very strange problem, all day with tests w/o luck..SMC controller looks to be working fine - mac starts, charge battery, cooler speed is managed by motherboard fine.
May be new HDD is incompatible?
Old HDD -
Looking forward for your suggestions.

Looks like this is hdd flex cable issue... I just move it when mac starts and partition select menu appears instead of grey screen or question mark. When I select partition (recovery or macintosh hd) after 20-30 seconds I see O w /.
Can anyone confirm that this might be? I will order new flex so this should be solution or not? I read a lot of google links and see that this is often problem for 2009-2010 macs.
Still waiting your advices
Apple should improve these type of cables as this not reliable as I think.
