Slow boot but only when booting from main hard drive

Hi... For some time now I've noticed that my MacBook Pro is seemingly taking an inordinate amount of time to boot up... I timed it today and it takes 105-120 seconds to fully boot up... I also have an external firewire hard drive that I use as one way to back up my Mac by using Super Duper to clone the MacBook Pro drive onto this external drive. Today I decided to set the external drive as the startup drive so I could do some tests on that system. Twas my intention to shut off some startup items and see what impact, if any, those might have on boot time... But before I made any changes to this cloned system, I noticed that, with no changes made at all, it was clearly twice as fast on booting as was the boot time when I was running off the main hard drive... I was surprised by this and tested the boot times several times and it was fairly consistent... It takes about one minute to fully boot when running off my recently cloned external firewire drive and closer to two minutes when booting off the main Macintosh HD on the MacBook Pro... Anyone have any ideas why this might be the case???? Any input would be much appreciated.... thanks... bob..

Boot from the external drive, erase the internal drive, then restore the clone to the internal drive.

Why won't my iMac 27" boot from external hard drive?

I have a new 27in Intel i5 dual core 3.6GHz iMac. It works wonderfully.
My question is this. I have a Pleides Ice Cube external hard drive with a USB 2.0/Firewire enclosure with a 500GB hard drive. I used diskutility to format the hard drive as a GUID Partition Table. I then used SuperDuper to clone the iMac OS 10.6.7 and Apps over to it.
I can select the external drive in System Preferences/Startup Disk to boot from, but when booting the iMac gets as far as the white screen then just stops loading.
I have tried both the USB connection and the Firewire connection (with a Firewire 800 to 400 cable).
I have run Disk Utility and repaired the disk and the preferences.
I have used Disk Warrior to rebuild the directory as well, but the iMac will not boot from the drive.
It does boot from the original DVD's and its own hard drive.
My old 24" iMac had no trouble booting from this hard drive or any of the others I have collected over the years, so I am reluctant to think it is the external drive. It is something to do with this particular processor Snow Leopard and external drives.

It sounds like something in the SuperDuper clone might not have copied well. To get the full answer on that I would check with Apple or SuperDuper to see if they support each other.
As a quick test, if you restart and immediately press and hold "option" on your keyboard do you see your external HD as an option to boot from? If so, click it and see if the boot runs any differently, but if you don't see it at all that could show that the problem is more deep rooted.
Personally, if looking in to either of those didn't give me any other info to go on, I would reformat and start the clone again. BTW, do you know for sure GUID Partition is the format you'd want to do this on? Generally macs use "Mac OS Extended" and some external HDs can use "FAT32" (if you want them to work well with Windows)
Hope that gives a little direction

Set Bios to Boot from 2nd Hard Drive

Hello HP forum!
I have a situation that I am afraid may be hardware related, so this is my last attempt for help before I let it go.
In this laptop, I have two hard drive slots with two hard drives. The second hard drive was used as an HP backup/restore drive as shipped from the factory.
I would like to format and install an OS onto the 2nd drive for easy-peesy dual booting. (This is a work computer, so easy + time-efficient + low-risk is optimal). I have actually done this already, but the BIOS does not seem to detect two bootable hard drives. In the BIOS (pretty sure not EFI) boot list, it simply shows the option to boot from "Notebook Hard Drive", which boots from the 1st drive.
In my 1st Drive's Windows 7, I can read the contents of the 2nd disk, so it is definitely functional. Also, replacing the 1st drive with the 2nd drive, I can successfully boot from it, so it is bootable. This seems to imply that my hardware understands that there are two drives, but the BIOS does not recognize that port to be a bootable option, but only a storage option... I guess?
My question is, then, how can I set up my computer to give me the option to boot from either drive? Is it even possible on this hardware?
Thanks
Rex

Did you make sure to update your bios as that could be something that might require a bios update? Also if you can't see or locate that second drive in the BIOS you might not have the option to boot from the second drive? Does the bios also give you the option to boot from the cd drive? Your asking us to see a boot bios screen and unless some has your same make/model no everyone will be able to confirm or see what your asking so unless you can do more looking at all your bios options you might not have the option to boot from the second drive port.

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!
This question was solved.

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.

Booting from external hard drive on intel-based MacBook Pro

Good day everyone. I know similar questions were raised in this community, but I still have some questions.
I have MacBook Pro(late 2011) with OS X 10.7.5 and external hard drive with Ubuntu 13.04, from wich i can boot succefully on my PC. But MacBook Pro will not boot from my external drive, no matter which key/combination i use during restart.
After googling I found some answers to my initial question, how to boot from external hard drive
https://discussions.apple.com/thread/1852633?start=0&tstart=0

As I understand I need to format my external hard drive into GUID partition type and this will be enough to be able to boot from it on my mac?
With this new partition type, will I be able to install ubuntu again on my external drive?
Does GUID partition type supports NTFS, ext4 and FAT32, linux swap?(I use ntfs for big files, ext4 as partition for ubuntu and fat32, because i use windows, linux and osx)
Will I be able to boot from my pc from my external drive with this new partition type?
What are downsides, if any, to GPT?
here is info on my e-drive

LowLuster wrote:
The only OS that will boot from an external drive is Mac OS X or maybe Linux. For OS X to be installed on any drive it need to be formatted Mac OS Extended and have GUID partition table.
As for Linux I'm not that familiar with it but again for a Mac to boot it need an EFI partition on the drive and I don't think that is possible with NTFS or FAT32 let alone the native Linux format.
Went to wiki to learn more on efi but found artice on uefi.
Operating system loaders are a class of the UEFI applications. As such, they are stored as files on a file system that can be accessed by the firmware, called EFI System partition (ESP). Supported file systems include FAT32, FAT16 and FAT12, and supported partition table scheme is GPT only. UEFI does not rely on a boot sector, although ESP provides space for it as part of the backwards compatibility.[26]
Here is FAQ on official uefi website.
Can UEFI Secure Boot be adopted and implemented by a variety of operating systems?
UEFI specifications are platform-independent, supporting multiple platforms and architectures. In addition, UEFI specifications are designed to promote cross-functionality, as well as to support broad adoption across multiple operating systems, including Windows as well as Linux-based operating systems. The specifications are robust and can potentially complement—or even advance—other distributions, such as Linux-based distributions.
And here is wiki article on GPT expaining OS support.
It is obvious both uefi and GPT are ok with Linux and file systems such as FAT32, ext4 and NTFS.
I guess there is no much difference(or is that the same thing?) between uefi and efi used in Macs.
In your answer to Stark Industries you said that mac can boot linux from external hard drive, well this is not the info i got of official website and it is still my question, because your answer is very inconclusive and your info is partially incorrect

Panther is installed but won't boot from iBook hard drive

Hello,
I made a similar post in the iBooks colors section of Discussions on this topic not quite knowing whether this was a hardware or software issue. I finally got Panther to install after using Disk Doctor to check for and fix errors on 9.2.2 (I would never use with OSX) and also rebuilt the directory while booted from an OS 9 CD and running Disk Warrior from a floppy and taking out the airport card. The Panther CD told me to restart the computer after installation. During the OSX start up from the hard drive I saw a gray screen and the dark gray Apple logo with the spinning gear then the computer crashed and a message appeared that I needed to restart the computer. After restart, the same sequence of events happened again. I have tried to restart from the OSX using the full retail CD used for intallation and the computer also crashes. I cannot start up from the Disk Warrior CD either. I have also tried make a Safe Mode start up and the iBook again crashed with the restart message appearing again. When I restart in OS 9 everything works perfectly, OS, airport and applications. I did have Jaguar installed on this iBook until five months ago, but incounterred issues with it and decided that more RAM would solve my problem. I then decided to initialize the hard drive and reinstall OSX after purchasing 256 RAM. The 256 stick of RAM was bought from ifixit.com and a guy there told me he thought that the logic board needed to be replaced. I explained to him that the computer works perfectly fine in the OS 9 mode, but he said that 0SX is more demanding and 9 can get by on less than perfect logic board. I also reinstalled the 128 MB RAM that was in the computer when Jaguar was running on it, but that didn't help either. I have scoured the iBook and Panther OSX sections of Discussions for any others having a similar problem, but not such luck.
I would appreciate any information or suggestion that you might have as to what may be causing this issue on my iBook.
Thank you.

Greg:
You have probably already tried this, but the first thing I would do is reset the PRAM.
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Also, check out this Apple article Your Mac won't start up in OS X.
Good luck.

X86 install was successful, but now I can't boot from the hard drive

I have successfully installed Solaris 10 for x86 from the bootable CD ROMs. However, now, after removing the CD-ROM from the drive and booting from the hard disk I am having problems.
The system attempts to boot. It displays the Solaris Primary Boot Subsytem v2.0 screen...pauses for 15 seconds...then reboots itself. And it continues this process.
However, if I boot to CD-ROM first, then boot to the Hard Drive, I have no problems. The CDE comes up fine.
We are running a 64 bit OS with a SATA drive that is supported. And as I mentioned, the install successfully completed.
Any thoughts are greatly appreciated.

is your hard drive connected as IDE0 - primary master? if not try doing so.

Hard drive crash in G4 - won't boot from 2nd hard drive

Hi,
My G4 has 3 internal hard drives: 2 on the ATA bus and one on a SCSI card. The main drive crashed yesterday. At least I assume it crashed: the first error was not being able to store a CD imported into iTunes, followed by a system crash and a request to restart. On restart it failed to boot, showing a floppy icon with a ? and repeatedly beeps twice. In an attempt to fix this I booted from my OS X software install CD and installed OS X on other ATA hard drive, however it refuses to boot from the second drive and shows a broken folder icon and is still doing the double beep thing. All suggestions gratefully received!
Thanks,
Andy

I do indeed. Here's what happened when I ran the extended test:
No Airport present. Logic board, mass storage and RAM all passed. I couldn't see if the modem test completed, but somewhere between the end of that and the video RAM test the screen was filled with a multi-coloured grid. Eventually there was a default catch:
code=300, %SRR0: 00000020, %SRR1:00081010
with the option of mac-boot or shut-down.
mac-boot also caused a default catch:
code=900, %SRR0: 01c10ffc, %SRR1:00003030
mac-boot then brought an alternate happy mac / folder with a ?
A reboot from there finally brings up the broken folder. All of these icons are very small OS9 style icons in the centre of the screen.
Phew!
Bearing in mind your suggestion about a blown stick, I have tried a swapping out each stick (1x512, 1x256) and rebooting with the same results. I also tried them in different slots and that made no difference either.
Blown video RAM perhaps?

IMac 24 Aluminum won't boot from USB Hard drive

I just got an iMac 24 from the Apple Refurb store. It comes with Snow Leopard, but I need to install a Leopard partition for my wife to ensure 100% compatibility with Photoshop CS3, among other things. I created a partition just for Leopard, so that's good to go.
I can choose the boot partition on my Leopard install drive when starting by holding the "alt" key, that's no problem. However, after I choose that USB drive, it reboots... over and over and over and over. To be sure it isn't the drive, I tested it with my Macbook Pro, and it booted up just fine. I tried another USB drive, same exact problem.
I don't have a Firewire external that I can repartition for the purpose of installing Leopard. I only have it on hard drive. Then I tried making a DMG with disk utility and burning it to a DVD+R DL, but it tells me the disc isn't large enough, even though it's 8.5GB and the image is 7.6GB.
Pulling my hair out here guys! Is this refurb a lemon?

The Leopard install DVD I used to make the image is not available, it got stolen along with laptop bag it was in last Spring.
Is it this "image" (clone) of the installation disc that you are trying to boot from a USB drive, or a full installation of Leopard? If it's a clone of the installation disc on a USB drive, there are a few considerations.
First, what type was the original Leopard disc (the one you lost)? Was it a retail disc (the type sold separately in a box) or one that came with another Mac model, such as a MacBook Pro. If it's the disc from a MacBook Pro, it will not work because your iMac is a different model. Those included disc usually only work with the model it came with.
If it's a retail disc, the other consideration is the version on the disc. If you look at that everymac.com profile page, it says that the (earlier) pre-installed version of Mac OS X is 10.5.6 (9G2030). If that retail Leopard disc was earlier than 10.5.6 (such as the original 10.5.0 disc), then it will not boot that iMac because, as I said in the first reply - +Macs can generally boot the version of Mac OS it came with, or LATER (up to hardware limits), but NOT earlier.+
If that USB drive you are trying to boot the iMac from has a full installation of Leopard, please post back.

Booting from External Hard Drive (Time Machine)

I just learned that my hard drive is failing. I haven't backed up my data for a while, so I bought a new 1 Terabyte Seagate Drive for Mac. It's one of the new models that don't need a power cord; you just connect it to your computer.
Anyway, a guy at the Genius Bar told me that I can use Time Machine to create a virtual clone on an external drive. I later realized that I might be able to boot up with my external drive and work with my cloned hard drive if my internal hard drive. I've done that with Carbon Copy Cloner before.
Anyway, that's my main question - can one boot up a MacBook Pro on a virtual clone created by Time Machine instead of using the internal hard drive? If so, how do you access it? I think I recall having to hold down a key (Option?) while the computer is booting up, which forces it to give you a choice of hard drives.
One more question: I've backed up some files on my new external drive - about 200 GB in several folders. My internal hard drive is 750 GB, of which about 180 GB is free. In other words, I need about 775 GB space on my external hard drive (570 GB for a virtual clone of my internal drive and 200 GB for the files I've already copied to it. Since it has 1 TB of space, that should be a breeze.
But can I use an external hard drive when it already contains files? In other words, will enabling Time Machine wipe out the files I've already copied to my external drive? Ordinarily, it wouldn't be a problem; I'd simply be replacing some folders with ALL the contents of my internal hard drive, including those same folders. However, I'm a little conerned because my hard drive is failing. I'm just worried that Time Machine might erase the files on my external drive, then poop out before it's finished creating a virtual clone.
So those are my main questions - can I enable Time Machine without wiping out files already copied to an external hard drive, and, once I've copied my entire internal hard drive to the external drive, can I boot up with the external drive and work on it? Thanks.

Hmmmm...I don't know what you mean by "restored," but it sounds like I'm out of luck (my OS X version is 10.7.5). It sounds like I need to purchase another external hard drive and use Carbon Copy Cloner to create a bootable clone on it, right? And could someone remind me how you access multiple hard drives when booting a computer? I remember you have to hold down a particular key(s) while it's booting.
Thanks.

My mac won't boot from the hard drive

Hi Everyone
Yesterday, I tried to dual boot my mac using the Bootcamp Assistant. The hard drive partitioned fine & then started the Windows setup. About half way through it found a corrupt file & cancelled the install. It went back to OSX absolutely fine & was working perfectly. I deleted the partition that had been created & then noticed that the amount of free space on my hard drive was missing the 20GB that I had partitioned off for Windows. I used OnyX to try & find the missing 20GB; it finished & then I tried to open Safari & received an error message. I tried again & received the same message so tried to restart the mac & ever since it hasn't wanted to boot using the hard drive.
It will boot from the CD & I can use the Disc Utility to see the hard drive (which makes me think that the mac is seeing it) & can verify & repair both the disc itself & the Disc Permissions but if I click Startup Disc I only get 2 options: The DVD itself & Network Drive. I also can't re-install OSX onto the Hard Drive as it comes up with an exclamation mark & wont let me go any further in the process.
I'm hoping that someone will have an answer other than erasing my hard drive & starting again (which isn't that big a problem as I backed up all the important bits before starting any of this!)

Why did you wipe the drive?
Were you having problems?
If you were those problem may be related to a failing hard drive and that is why the TM backup could be restored.
In you topic header you say the system won't boot from the SL DVD, But it di for you to wipe the drive. Then it should again boot from the SL DVD.
Insert the DVD and reboot, hold down the Option key and select the Optical drive, SL DVD, as the Boot source.

Won't boot from USB hard drive?

Hi, all. My daughter has a brand-new Aluminum Macbook a week old, with all Apple software updates applied and everything running smoothly. She has a Seagate FreeAgent Go external USB 2.0 hard drive divided into two HFS+ Journaled partitions using the GUID partition scheme: a large partition on which to back up her internal drive, and a small partition for use as an emergency boot "disk." We've used the latest version of SuperDuper to make a bootable clone of her internal drive on the large backup partition, and I've just begun installing Leopard from her MacBook installer DVD onto the emergency boot partition as I write this (using my own computer). After 25 minutes, the installer DVD is still being "checked for consistency"; I hope things will finally begin to move along faster when the installation actually starts.
We'll see what happens when that installation is done, but before I began it, I checked to make sure the SuperDuper clone on the backup partition would boot the MacBook. To my dismay, it did not, although I held down the Option key during startup, selected the backup partition in Startup Manager, and clicked the arrow to proceed with booting from that partition. The MacBook booted from its internal drive anyway.
You'll note that I'm not a Leopard or Intel Mac user myself, so I'm not familiar with any issues that may be more familiar to regular users of that OS or of Intel Macs. Can anyone tell me whether SuperDuper has problems creating bootable USB clones that work in Leopard or on those machines? Is there something else I should be doing to boot from the clone we made, instead of using the Startup Manager? Any other thoughts on why this hasn't worked?

I have noticed that the start-up disk appears just about anywhere except in the upper right-hand corner. I too, was convinced once that I was booted from the wrong drive. However, I have implicit faith in SD and since it has never let me down, I searched and found the boot drive hiding amongst some files littering my desktop.

Hard drive dead/Boot from external hard drive?

My hard drive failed and I need a new one. For the time being, I'd prefer not to open up my iMac and replace the internal hard drive. I have an external USB hard drive and I cannot install OSX onto this drive (strangely, it takes the first disc but not the second).
Is it possible to boot and run an iMac G5 from an external hard drive? If so, what is required for hardware and what steps need to be taken?
If not, what course of action would you recommend?

It is very easy to boot an iMac from an external drive, but the drive should be a Firewire drive. Get one, then get SuperDuper!, which will enable you to clone your data and system to it. You can then choose the external firewire as your boot drive and operate without any problems.
Apparently, there are ways to boot from a USB drive, but they are complicated and a firewire drive is very straightforward and fast.
Let us know how you make out,

My PB G4 won't boot from any hard drive..stucked in apple icon..

At first, it didn't boot from the internal hard drive...
I could see the apple icon with grey background, but the little runing icon under apple icon didn't appear. There is no sound from the hard drive either...
I tried removing and replacing the RAM, didn't work either...
I have the powerbook CD with apple hardware test, I ran it. It went though a detail test and showed no errors or problems....
And then I tried to start up from the powerbook CD, it works and I was able to go to disk utility. However, I cannot complete verifying disk permission because of a lot of problem, sometimes it said "communication error with disk manager" and sometimes it got frozen and sometimes it just simply stop moving (not frozen, but just not moving, the disk is quite also too).
then I tried to boot from my USB external hard drive, I had my backup in it. However, it is the same as booting from internal drive, no running icon below the apple icon. Also, the external hard drive did not make any sound.
I have never experienced this problem... please help...

Have you added any hardware or new software recently?
Have you tried a safe boot? Hold the shift key while you boot - this does some disk maintenance and doesn't load login items. If this works, try booting normally.
If you can't run Disk Utility verify permissions from the OS X CD did you also try to verify or repair the disk? If this won't work due to errors, you may want to consider a program like Disk Warrior to attempt to repair the hard drive. You can find it at http://www.alsoft.com/DiskWarrior/

Memory gone from main hard drive

I imported a movie I video taped from my camera to my main hard drive and had 9 Gigs left. After I had finished my editing I was exporting it to and external drive and I when it got to about 34 % it said i had no more memory left but before I started exporting I checked the external and had 130 Gigs left so i look at my main drive and it had zero KB left whats going on and how do i get my gigs back ?

Where are the render files going? How big is system drive? Sounds like it's way too full to run properly. Rebooting should clear up some VM, but you'll probably have to dump something.
