XP boots on external FW drive

I didn't think this was possible but I just did it. Does SL now allow this? Because it is working.
What I did was to use winclone to image the bootcamp drive, and simply run the restore from the bootcamp image to an external FW drive. Then run Startup Disk and it sees the external drive. Set the external drive for reboot and voila! It boots native oted XP, everything working.
Haven't figured out yet how to make Parallels see it.
Thought you would all like to know.

I'm not sure which installer was used, I can't recall the size of the download and the file size is not in the log (maybe something Apple could add to the log for the next update). I can tell you the machine came with 10.4.2 and I updated using the Software Update feature, so whichever one it uses for 10.4.2 systems. I'd assume it was the smaller 93MB installer.

Boot from external Firewire Drive-cannot repair or optimize internal drive.

Hi all
Connected my new 300 GB Seagate External Firewire Hard Drive today.
Installed Tiger from DVD. Updated to 10.4.3.
Installed Tech Tool Pro 4. Updated to 4.1.1.
Booted from External Firewire Drive.
Disk Utility cannot Verify or Repair internal drive. Does not say or do anything.
Tech Tool Pro cannot repair volume or optimize. Says, "Cannot Unmount Volume."
Is there a fix for this?
Thank you for the help!

Hi
I did name the new external completely different from the internal.
After booting from the external Firewire Hard Drive, I tried running Disk Utility and Tech Tool Pro from both drives. No matter which drive I run the Utilities from the same things happen every time...
Nothing happens when trying to use Disk Utility to Verify Volume on internal eMac Drive.
Tech Tool Pro says, "Cannot unmount volume" when trying to check Volume or Optimize internal drive.

Ibook g3 M2453 boot from external DVD drive

Hi, I'm Simon from Germany.
I have an iBook M2453 Mac OS X and a lot of dvds.
But the iBook has no DVD drive. So I bought an external DVD drive. But no matter what I do during boot (press the C key or alt)
I can not boot from external DVD drive.
Please help me
Thank you.
Simon.
PS: I have translated the text using Google translate

Hi Simon,
the iBook is able to boot from USB, but this is not expected behaviour and not supported by Apple.

There are some external enclosures that do the trick.
But only when you press ALT after Power on. (Select a startup volume via the Startup Manager)
External enclosures with Prolific PL-3507 chipset (Firewire/USB Combo)
You will find them on Ebay Germany
I have a Delock IDE>USB 2.0 enclosure for 2,5" HDs
http://www.delock.com/produkte/gruppen/Geh%C3%A4use/Delock_25_external_enclosure _USB20_42365.html?setLanguage=EN
that works also.
Hallo Simon,
das läuft nur mit einigen wenigen externen Gehäusen. Such auf Ebay nach "PL-3507"
und nimm eins mit Firewire und USB Anschlüssen.
Ein Festplattengehäuse von Delock für 2,5" Festplatten ging auch ( Link oben)
Ein Boot ist nur möglich wenn du die ALT Taste nach dem Einschalten drückst und dann über den Startup manager dein Boot volume auswählst.

All users GONE except for "Other"...and CANNOT boot from External DVD drive

I booted the iMac (Intel...the last one with the White Bezel) tonight, and all of my users were GONE except for "Other." The internal Superdrive has had a disc jammed in it for months, so instead I have an OWC external USB/FW400/FW800 DVD drive. Snow Leaopard.
I need to boot from the SL install disc, but that must go into the external drive...which, as it's been since I upgraded to SL, the Mac sometimes sees and sometimes doesn't. Right now it can't see it. Which leaves me a big pile of crap, doesn't it?
So, what to do? I can't boot the internal drive because it's jammed with a DVD (or I spend $300 to replace what should be a $20 optical drive in it), I can't boot the external DVD drive because the iMac w/Snow Lepeord can't see it, and, meanwhile, all of my photos, etc., are on my Time Machine backup drive...which, as long as I can't do any of the above, just sits there...useless.
Can you tell I'm a bit frustrated with this?
I've reset the PRAM. I've rebooted. I've held down all sorts of combinations of keys. I've tried every single interface type on the external drive and the same thing - the drive can't be seen by the computer.
Has the internal hard drive failed? Nope. I'm tying this using the Firefox browser that's running on my Windows XP installation via Boot Camp on the internal hard drive.

Thanks, but no luck so far.
I have an old iMac G3 downstairs, and I connected it to the machine via Firewire. I could see the disk on the 24" iMac, its folders, etc. I wanted to see if I could install OS X via Target Disk Mode from the old machine to the new one, but it's a PowerPC machine and you can't do that. Maybe you can't do that from ANY iMac...I'm not that experienced.
Now the iMac isn't booting at all to Windows via Boot Camp - it's been booting for 45 minutes now with the "WinXP" logo, but nothing. I'm about to throw it in the car and haul it over to my parents, who have both a Powerbook and a 27" iMac. Maybe it'll work there. Who knows.
Other ideas...replace the internal hard drive (cheap)...if that doesn't work, I'll just sell the thing. I'm not going to sink $300 into the thing when I can get a new machine for around $600-$700. I may go to a Windows7 machine on the desktop and a Powerbook...maybe even an iPad.
I really want to love this iMac. It's my first (well, I did have the G3, but that was just to play with) Mac. It's given me a ton of problems since I bought it new. It's always been a "stock" machine - nothing weird done to it. I was hit with an iMovie update once, and that broke iMovie. Even the new iLife 2009 didn't fix it. Then, the internal optical disk drive failed. I couldn't believe that Apple used a proprietary optical drive rather than a stock Pioneer model. Price for the drive alone? $200.
I installed Snow Leopard 2 months ago, and that completely broke my ability to use external optical drives. Sometimes they work...most times they don't. This is an ongoing problem that many people are having (check the forums)...but no fix. Where does that leave me? With a useless computer.
So, I've boiled it down to this: I love the Mac software. I hate the hardware. Sure, it's pretty, but if something goes wrong, get ready to pay. I hate that Apple knows about problems, yet does nothing to address them, like the problem with external optical drives and Snow Leopard.
I bought the Mac because I was sick of Microsoft not being able to simply produce an OS full of security holes. Often times I read people bashing supposed "driver ****" with Windows, but look at what users of Windows machine are demanding of Microsoft - "please make my software compatible with the trillions of combinations of hardware that can run the os...all the way back to stuff that was created in the mid 1990s." Meanwhile, from my experience, Apple can't get their software to work with their own proprietary, supposedly vertically-controlled hardware.
Windows7 is a not bad OS. It's got it's faults, of course. But, if my optical drive failed in a Windows box, I'd have it replaced in 10 minutes...with a bluray drive...that can write...for under $100.
I use my computer for pictures, etc. In fact, we were ready to send off to iPhoto for our yearly photo books. That's not going to happen, as the photos are forever trapped on my Time Machine backup drive (lesson learned: dump photos to a generic format...fat32 works...just in case you decide to switch from Mac to Win7). iLife is great. MS Office is great, too, on the Mac. I love the little things the Mac does right.
After years of screwing around with my Windows box, I wanted a computer that acted like a consumer electronic device. That's not what I've gotten.
Ugh, so now do I buy a Mac Mini for $700, a new iMac for $1,400, or a Macbook Pro and a mac mini?
...or...do I continue to work within this silly Ubuntu Linux world?
Whatever the answer, I wish I didn't have to ask the question now.

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

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

Wont boot if external hard drive is on

PC wont boot if external hard drive is turned on. If I turn them off boots fine. This has happened since day one.

Hi,
Turn "them off" implies more than one.
You might be experiencing one of three issues or all or them.
1. The external HD needs a firmware upgrade to be compatible with your PC
2. The BIOS boot order is incorrectly set which is typically not the situation with new PCs.
3. The external HD is drawing excessive current from the USB port.

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

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,

Did 10.4.6 break booting from external hard Drives

Hi
This afternoon, I tried to clone my internal Hard Disk to an external drive. I do the regularly using Disk Utility, and I have not had and problems doing this until today. In fact, when I acquired my Power Mac three weeks ago I cloned my iMac's drive to the same external drive, and then cloned my Power Mac's drive from the external. I did have one hiccup during that last step - I had cloned to the PM's drive while running the PM off the external drive, and the clone was flawed, so I booted using my Tiger DVD and re-cloned the drive using Disk Utility off the DVD. All went well, and my Power Mac's been running flawlessly since.
That was before the 10.4.6 update. Usually, when I have a good known bootable external hard drive, I will only back up my home folder onto the drive. If I've gone through an OS update, or have some major application changes, I will opt to re-clone my internal drive. I did this today.
I tried restarting from the external drive. Yes, I did remember that 10.4.6 did offer that lovely second chime before truly starting up after upgrading, so I waited to see if spotlight was indexing the external drive. I waited 25 minutes. That only thing I saw was the grey apple and - maybe this is a clue - a couple seconds after showing up, that moved an half an inch down screen.
Has anybody been able to clone 10.4.6 to an external hard drive and successfully boot off it? Is my problem of today related to my problem of a couple weeks ago, and I need to run Disk Utility of the Tiger DVD to get a good clone?
My internal drive = 128 gigabytes, external = 118 gigabytes, about 29 gigabytes being transferred.
Thanks in advance.

Wish I figured out I was in the mail and address book forum before I posted. Oh Well.
It seems that there might be some sort of weird thing going on between my computer and Disk Utility when booted in the full OS. Earlier, I tried cloning my internal Hard disk using Carbon Copy Cloner, and it worked. My Power Mac boots off the external disk fine and everything runs flawlessly.

Cannot boot from external CD drive

Hi, I am trying to do a clean install of Snow Leopard on my Macbook Pro Core i7 (Late 2010).
First off I should note that I took out the CD drive in my macbook and put a 60GB SSD drive in its place, the SSD is blank and formated Mac OS (Journaled). This is the drive that I want to install the new OS too.
Anyway I went to the store to buy Snow Leopard (I lost the DVD that came with my mac) and am using that try to install the OS. I am currently using an external optical disk drive to install the OS (http://www.amazon.com/gp/product/B0044DEDBG).
The problem occurs when I load up the CD. When I start up my mac holding the "c" key the external optical drive is show on the screen. But when I select it the computer just stalls on the grey apple logo screen.
I have also viewed the CD in Snow Leopard and tried installing it that way. However when it automatically restarts my computer to boot from the CD it again stalls on the grey apple screen.
The "utilities..." button on the CD also does the same thing as above when I click it.
How can I boot from this external optical drive without getting stuck on the grey screen?

You need replacement original disks(phone Apple Support) and not a retail package.

Problem booting from external DVD drive on Lenovo S10e

Hi,
I recently purchased a new Lenovo S10e ideapad, a few weeks prior to that I purchased an external DVD rewriter drive manufactured by LG, the drive works perfectly on every computer I try with the exception of the Lenovo ideapad S10e.
The thing is that the drive is being recognized and installed by the Windows XP Home Edition the S10e came with but when I try to boot a bootable CD using then drive on the S10e ideapad I almost alwasy fail to do so.
I set the S10e BIOS to have the USB CDROM as first boot device, in addition I used the F12 key to use the boot menu to choose the boot device, in 9 out 0f 10 atempts my external drive will not show in the boot menu and when choosing the enter setup option I see that the BIOS do not list it as the USB CDROM, instead it says "USB CDROM:" rather than have the drive name after it.
In the 1 time out of 10 it does work the BIOS seem to be identifying the drive and it shows in the boot menu, however I cannot work with it for a more than 1 minute without it stopped being recognized again.
The problem seems very strange to me as the drive works under the windows operating system and do not have any problem whatsoever on other computers, I have tested the external drive on my PC, another Mini Laptop from LG and a GIGABYTE Laptop (Normal one), all of which had no problems recognizing the external drive and booting from it.
I will really appreciate if I can get some help with the problem.
Thanks.

I've had a similar issue with X61 and the external DVD drive from Lenovo.
In my case, it was the power issue. On the back of the drive, there is a small table says that the drive needs a 3.0A 5V power input. One USB 2.0 port can only provide 0.5A. I don't know if the drive has any special, low power mode, but I suspect that even if it has, 0.5A is still not enough to fully power it. I've checked the current with the multimeter, and at peak times, the drive draws 550mA. Even then, it makes a stuttering sound for a few seconds, before finally spinning the DVD disk. I've also noticed that the DVD works most of the times when it's connected to the left USB port. That may be because of how the laptop's internal power circuicity is laid out (+separate USB host controller for each 'side' of the laptop). Another thing that seems to help is to disable all 5V driven devices that the laptop uses: the wifi card, bluetooth, any additional devices connected to the USB bus / to the ethernet port / SD card port (I'm not actually sure which of the devices are 5V and which are 3.3V, but the best option is to disable all of them), maybe even remove the battery (if it's charging). Finally, the DVD drive works better if the laptop was turned on and runnig for some time, rather than it being turned on "a minute before". Also, in the BIOS, there is a setting that changes the speed of the DVD drive, but switching it to "low" didn't seem to affect the external drive (at least not before Windows boots up).

IMac won't boot if external hard drive running Time Machine powered on

Upon rebooting, my iMac 3.06 GHz Intel Core 2 Duo with 4GB RAM, running OS X 10.5.4, locked up in a gray screen, the "gray screen of death."
At the recommendation of the Apple Tech Support rep, I turned off the iMac using the power button, and rebooted with my USB and Firewire devices removed.
The iMac boots fine with everything except my G-tech drive 1GB external hard drive running Time Machine with no partitions, attached using a Firewire 800 cable.
If the external hard drive is on, I get the interminable gray screen.
If I boot with the external hard drive powered off and then power it on after I'm at the Mac desktop, the disc image mounts normally on the desktop.
I've already repaired all disc permissions and it doesn't help.
My external hard drive has used 907 of the 931 GB true capacity. Supposedly, Time Machine removes the old files to make room for the new files.
Time Machine itself is running properly once I get my iMac booted in this peculiar way.

Raja,
Do a SMC reset perhaps even a couple of times and see if that helps. Also in System Preferences + Startup Disk make sure the internal HD is selected.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Restore Disc Will Not Boot From External DVD Drive

I am using an original MacBook Pro that I decided could use a good restore, and started to clean house. The optical drive is broken, so I am using an external USB drive. I inserted the restore disc that came with the computer (It has OS X 10.4.6 on it), erased my HD, and proceeded to install Tiger. However, setup froze while installing Photobooth, and I was forced to shut down the computer.
I'm trying to get my Macbook Pro to boot from the restore disc that came with it so I can try setup again, but it won't work. If I hold C during the boot, I get a flashing folder with a question mark over it. If I hold option, I get a cursor, but just a blank, gray screen. In both instances, the external DVD drive is active and reading the disc, but I'm not getting any results on the screen. I've also reset PRAM.
If I can just get my computer to boot from the disc, I should be able to get back on track. Thanks.

When I press option during boot, nothing happens. Just a gray screen and cursor, like I described above. I haven't been able to test the external drive yet on another mac to see if it is bootable because I can't find the other computer's boot disc at the moment, but I'll try later with something else.
I have been able to access the drive through Target Disk mode successfully though. Is there something in particular I should do with the files? The folders are:
Applications
cores
dev
etc
Library
OSInstall.mpkg.998YblbM
System

Can "Refit" Be Used for USB Boot From External Optical Drive?

Since the new Mac Mini 2011 has no optical drive, how would one make a generic USB 2.0 optical drive act as a boot device? I have heard that a utility called "Refit" can alter the boot loading order and device choices in Macs. I suppose it is also possible that the new Mini may already be set up to boot first from USB. I would appreciate any comments. It would be nice to have some kind of optical drive boot option for Windows installation and other possible utilities that need to boot before the OS in order to work. Maybe I will have to take my external optical drive to an Apple store to find out. Hope not. I also suspect that a USB keyboard will be mandatory for "Refit" and the boot drive to be used before Mac OS X is loaded.

No utility should be needed.
You can hold the Option key down during the boot process to select which drive you wish to use as a boot device.
Also pressing and holding C boots to the optical drive.
There is reportedly a pretty broad number of USB optical drives that people have been able to use as a boot device, as inexpensively as $30. I don't know that there is a specific list though. I would research whichever model you wish to buy with a quick google search or searching that model here in the forum.
Or maybe somebody will have a recommendation which one they have.

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.

Slow boot from external usb drive

I just upgraded my daughter's macbook to the latest fixes on her internal drive. I reformatted her external LaCie drive to Mac OS Extended(Journaled) and did a restore. I did notice that there are less files on the internal than the external drive when comparing immediately after the restore. When I try to boot from that drive, it takes 10 minutes to boot the system. It takes about 7 minutes before I even hear any drive activity. In the past this system used to take about 2 minutes to boot at most vs 30 seconds from the internal drive. I have repaired permissions without seeing any effect. I did attach another USB drive that had a copy of her old OSC 10.5.8 image and that booted in less than 2 minutes. Any thoughts on what could be causing the long boot time on the external drive? I have seen comments on GUID formatting. Doesn't that come automatically with Mac OS Extended(Journaled) on an Intel machine? Should I have selected an option when doing the format to specify GUID? I did run a verify Disk as well and the extrnal checked out without any problems.

+" ... and did a restore ..."+
How, of what, from where, to where?
+" ... I have seen comments on GUID formatting. Doesn't that come automatically with Mac OS Extended(Journaled) on an Intel machine? ..."+
No, it does not happen automatically when you format the drive. GUID is a partition type, not a format. You specify GUID partition scheme at the time you partition the drive. Formatting is a separate operation, occurring after partitioning. Drives that will be used to boot an Intel Mac must be GUID partition scheme and formatted as Mac OS Extended Journaled.
