Boot Intel Mini from USB external drive

Hi -- can anyone confirm that Intel MacMini can boot from an external USB (NOT firewire) drive?
I see plenty of notes that people boot from firewire, but I haven't seen anything about USB.
Thanks for your help!!

Alan, SATA drives are "faster" than ATA drives, but I don't think the have any other advantage, and unfortunately you lose that advantage when you opt for a USB 2.0 or FireWire 400 connection (they both are slower than SATA or ATA, so it's like a bottleneck). And while USB 2.0 is theoretically faster than FW400, it real-world use FireWire is faster.
There have been reports of people successfully booting off a USB drive on Macintels, and some of them even where Mac minis, at least as far as I can remember. Unlike on PPC Macs, in order to boot off an external drive, you have to partition it with the GUID partition scheme. I'm not sure that cloning a drive would automatically do that, which could explain why Seedling can't boot off his clone ...

Can't boot my Macbook from an external drive

Hi there,
After my internal hard drive failed, I put an older (temporary, and somewhat small -- 100gb) internal hard drive onto my Macbook, and using a time machine used an external drive to recreate the data and OS that were on the internal drive that failed. Part of the reason I did this, rather than just buying a new internal drive, is that I live in Germany and my family is coming to visit in a month with a brand new mac, so I'm hoping to just run everything off this external drive until I get the new computer and can transfer all my data over.
Anyway, I can't get the computer to boot from the external drive. It has the right partitioning scheme (GUID), my mac is willing to assign it Bootup Status, and when I browse the contents of the external drive, it basically looks fine. The termporary internal drive, incidentally, is running 10.6.7 as well, and using time machine I put my old applications on it, but not my user data. I can boot from that internal drive, but when I try to boot from the external drive I get stuck on the grey screen. Any idea what might be the problem and how I might fix it? Or a suggestion about how I can run my computer off this external drive until the new mac arrives next month?
A few technical details:
My macbook is about 5 years old, and when I check the "about this mac" tab it says it is running 10.6.7 OS, with a 1.83 GHz Intel Core Duo processor and its memory is 2BG 667 MHz DDR2 SDRAM.
The external hard drive is LaCie, 500gb, firewire 800 cable (and with the option to use a USB port too), which uses the macbook as its power source.
Thanks for your help and advice.
Bernie

Hi,
Thank you for your time.
Even if Disk Warrior can help recover/restore my files i think replacing the hard drive is necessary, right ?

MDT 2012 deploy OS from USB external drive failed - need to unplug and plug it once again

We are using MDT 2012 and deploying Windows 7 using media (USB external hard drive). We can successfully deploy Windows 7 32 bit using this method but there is a problem with deploying Windows 7 64bit. This problem appears only on HP EliteBook 840. We can
boot into WinPE 64 bit and can start proper task sequence, all image is applied then after restart, before logon screen appears there is an error saying that cannot find litetouch.vbs script. After clicking ok, I can logon to Windows and there is no usb external
drive recognized. But when I unplug and plug usb drive once again it is recognized by Windows and can be used. I can see that Windows install some drivers just after plug it again
I checked BIOS looking for some USB power options - there is no such settings. And 32 bit deployment works ok. So this is not a case. Looks for me like a problem with proper usb drivers for 64 bit. I download all drivers from HP website (driver pack and
drivers only for USB 3.0). We are using make and model matching in MDT - works ok for all the rest hardware models. Any idea how to troubleshoot it?

Not sure what's going on here. Is this a USB "Flash" drive or a USB "Hard Drive". There *Is* a distinction.
I *thought* that MDT would copy itself to the c:\minint\scripts folder to continue installation.
Next time, when you see this error, Press Shift-F10 to get into a cmd.exe prompt. Can you find litetouch.vbs on any of the drives? Does the USB Drive appear?
IF in fact, the USB Drive is not appearing after the 1st reboot, then you have a problem. Why did the USB 3.0 driver not install. Check the Driver Installation Logs to verify.

Booting two Macs from one external drive: 10.8 and App Store?

I boot two Macs from one external harddrive. Does this mean that when 10.8 is sold exclusively via the App Store and thereby linked to a unique hardware identifier, I am going to have issues with activation/authentification each time I switch machines? I have avoided the App Store since I discovered that an app I bought there, and which I really needed to open automatically on log-in, had to be manually re-activated with my Apple ID after every switch (so that I eventually deleted it and reverted to an earlier, non-App Store version).

Welcome to the forum!
There are a couple of "solutions" to your problem. The easiest, and possibly the best for you (although it is a bit slower) is to copy your catalog onto the external drive as well.
Then when you plug in the drive, you will always have your latest catalog for access.
The other way is to keep a local copy of your catalog, and copy it onto the local drive as a way to transfer it from one computer to the other.
This has the problem of possibly not being in sync, that is, you forgot to copy it over once and did some editing. Then you would end up with essentually two different catalogs, instead of one in two places.
You can copy the catalog either with your OS, or you can "export as catalog" and specify the external drive as the destination. Then, on your other computer, "import from catalog" and only take the meta-data settings (it's on the import dialog box).
Personally, when I'm traveling, I have my catalog on my external drive as well. It just makes life easier, and I don't have to worry about it being out of sync, or losing it (and not the images).
So, I would go with the first method, at least to start. To get your catalog over there, you can either export as catalog or copy it, either one will work.
You can find the location of your catalog file (if you don't know where it is) in the catalog settings menu prompt. Both the location and the name will be displayed.
Cheers!

Going from 10.3 to 10.5... can i still boot 10.3 from an external drive?

I want to switch from 10.3 to 10.5, but I have some important software and hardware that only works with 10.3. Can I copy my current hard drive information to an external drive, and then essentially boot up my old computer setup from that external drive whenever I need to use 10.3?
How would I go about doing this?
thanks!

System Preferences >> Startup Disk >> choose the one you start from and press restart. Or boot to Startup Manager.

Trying to move aperture library from USB external drive to FW 800 external drive.i can see the projects but no thumbnails. Error application not responding. Verified permissions before started. It's been 3hours. Recommendations please

I have consolidated iPhoto into aperture 3.2.2 and now have both aperture and iPhoto put consolidated library on 2.0 USB external drive. Have been removing duplicate photos from 23,000 down to 15,000. Problem in trying to close aperture and now tried to move library from 2.0 USB to 800FW and can see projects but no thumbnails. Aperture error now reads not responding. Can I repair library on 2.0 at this point?

Sharon,
did you do anything else besides copying your library to a fire wire drive after your last post Aperture not responding ?
Since that library probalbly already needed fixing, I'd recommend to force quit Aperture and use the "First Aid" to repair your Library.

Boot from usb external drive

Mid 2011 MacBook Air does not check the usb port for attached devices after a restart, but does after a shut down and power up. So a "restart" to a USB external clone drive from the Startup Disk Manager does not work, only works if you shut down, then power up. Anyone notice this? (it also does not work using the "option" key startup method, but does if shut down and power on)

Ok heres the deal I have tried every single way under the sun to boot this g5 (except firewire). I get the ? folder aka hard drive failure. I took a harddrive out of a windows computer an 80gb Seagate Barracuda. I didn't have an enclosure except my WD My Book which I wasn't gonna take apart. Also I do not want to spend any more than I have to. So I took the Seagate up to a computer repair shop and they formatted it in APM and they installed my OSX 10.5 dvd on the disk for 20 bucks (ya I know shoulda just bought the enclosure). Bring It home. Again ? folder. So make a partition on the WD Mac OS X extended (journaled) mount the dmg no go ? folder. I have tried all the open firmware work arounds with the WD (usb) and thumb drives in every slot. It also spits out the dvd at boot and after holding down C along with the Open Finrmware command "eject disc" states can't OPEN the EJECT device (I have to open the drive with the pin hole initially) . Also if I hold option down at boot it does not list the drive that I took to the repair shop, or the WD, or the USB. It runs great lol it just won't boot! All my other macs are intel based but I know leopard is compatible with both so maybe I could install leopard on my macbook air and put it in target disk mode. I guess after having to buy a firewire cable and adapter as both my macs carry thunderbolt ports. Any suggestions? I'm starting to think I might need to get a firewire enclosure so I can take a look at this myself. Is there a way to format a drive in Apple Partition Map on an intel based mac I don't see an option for that in disk utility?

Boot camp install from USB Flash Drive

Hi Folks,
I recently purchased a new Macbook Air. It has 10.8.3.
I used the Boot Camp Assistant to set up the computer for Boot Camp. It went through all the steps: First, it formatted my USB Flash Drive. Next, it copied Windows installer crap from the my ISO to the USB Drive. Next, it downloaded the Apple Drivers and put them on the USB drive. Next, it restarted in order to boot from the USB drive.
This is where I hit a wall. The computer will not bpt from the Flash Drive. It is as if the control panel has set the startup disk to "BOOTCAMP" instead of the flash drive. So when the computer restarts, it just says "No bootable device - insert boot disk and press any key."
How can I get it to boot from the flash drive?
Thanks In Advance
Andy
Corrected the error message to exact phrase.

Hmmm... interesting... My sites I found suggested otherwise. I tried three diferent brands of jump drives and none of them actually booted the Macbook Air. The Boot Camp Assistant used them all just fine, but booting was the issue. Glad you got it to work. Would you mind posting what brand you used so other reading this thread in the future could learn?
Also, were you just using the BCA or, did you do some other process to make it bootable first? Since the BCA formats the drive, I would think any process done ahead of time would be thwarted (as mine were).
Thanks!

How to boot Powerbook G4 from USB hard drive using Mcintosh v10.5.2 install

Well I am Rider and I have been a mac user for at least 8 years. By far these OS's are the most advanced I have ever seen and it blows every other OS out of the water. My dad bought a Powerbook G4 8 years ago and it lasted 3 years till the hard drive crashed. My dad had it taken out and we still have the Powerbook G4 under the bed. When we bought a new macbook that came with the install disk 10.5.2, I was wondering if there was any way to use a USB 16gb Flash Drive as a hard drive and start up disk.
I have tried sticking the Install Disk in the G4 and after it says choose language for primary install, it says 'Mac OS X cannot be installed on this computer'. It gives a few utilities to use such as Disk Utility, Start up Disk, Net Utility, etc.
So if anybody knows how I can boot a G4 from a USB using Mac OS X install disk 10.5.2, *PLEASE HELP*.
Thankyou,
Rider M.

Hi,
Since you are trying to boot from 10.5, post in the Leopard forum here.

Booting my G4 from an external drive?

hi!
I'm relatively new to Macs but have upgraded my g4 graphics model with a new graphics card, (Ge force- i think, and a Newer tech processor, as well as more RAM) and a fresh copy of OS X 10.5.2 so that i would be able to run the Music creation program LOGIC 8. The problem is the computer keeps crashing in the middle of my work. The CPU is running at 2 GHZ... the logic specs said that this would be fast enough, so Im not sure if this is the problem.
I think it maybe something to do with my relatively small hard drive?
I'm using a Freecom external hard drive (400gb) to store all my files, and i was wondering if i could boot OS X from this and whether this would solve or cause any problems?

When you say "crashing" how is this showing up? Is the beach ball spinning and you can't seem to be able to do anything? Do the windows all disappear and nothing is on the screen? Does an error window show up? What? There's a million ways that a computer can tell you to go get lost.
Also, you said you added more ram, but how much ram do you have? Graphics is ram intense and it is easy for it to run out of ram, try to go to virtual ram and just crash for no reason. To check on that, in Finder (at the desktop), pull down the menu "Go". Down near the bottom of the menu there's "Go to folder....". Enter /var/vm/ and push the go button. This opens up the vm (virtual memory) directory and you can check to see if you have lots of files called swap0, swap1, etc. If you only see swap0 you are in the safe zone. Loads of files mean lots of swapping going on. It keeps running out of ram. This is just one of many reasons why your computer is crashing so don't give up if this looks good. Note: you can navigate to the directory to look in, but using this menu pick is convenient if you are going to be checking from time to time since the entry seems to stay in there making it an easy menu pick.
Also, in the utilities folder open up console and look at your system log for errors. This is a valuable tool for narrowing down the cause of crashes.
I'm not a graphics guy and these are just to get you started. Japamac and others here do all the graphics work.

How to boot OS DVD from a external drive (holding down "C" does not help)

Hello friends...
I am updating my girlfriends Tiger G4 to Leopard. She has a internal CD drive, but not a internal DVD drive. I have a external Pioneer DVD USB drive that I have plugged into her G4. I can place DVDs in it and load software from it.
However, I can not seem to boot a Leopard DVD from it. At first I installed the DVD and it came up on the desktop. I selected the correct icon, and it said it now had to reboot which it did. I selercted "reboot". I held the "C" key down but in all attempts, it would boot to the desktop of the tiger OS. So I went into "start up drive" in preferences, and saw the Leopard DVD. I selected it, then selected reboot. It would still bypass my external DVD drive and boot to the tiger desktop. The external DVD USB drive is called Pioneer DVR-X122.
Any help on getting her Leopard DVD to boot from this device so I can update her OS? She has a lot of free HD space, and over 1 GB of RAM. Her G4 meets or exceeds all requirements from Leopard as far as I can tell.
Thanks in advance.
Sincerely,
jack

Any help on getting her Leopard DVD to boot from this device so I can update her OS?
You can't use that drive. An internal or FireWire drive is needed. If it and the G5 are physically close to each other, connect them with a FireWire cable, insert the DVD in the G5, and start up the G5 with the T key held down.

SimpleTech Mini 320gbFW/USB external drive freezes system

This is the second unit I've attempted to use with my iMac, with the same results. I'll format it with 3 partitions, using GUID, and Extended Journaling. I'll start consolidating my iTunes Library to one of the volumes, then about a third of the way along, it will freeze, "beachball" for about 20 minutes, then iTunes will say the disk can not be read or written to. After which, the entire Finder will beachball, and I'll be unable to unmount or restart as long as this thing is connected. This occurs using both USB and FW connections. If I drag and drop files directly, it'll work for about 10 minutes before the same thing will happen...files won't open, and the beachball...always the beachball. I've formatted this thing repeatedly, using Leopard and Tiger versions of Disk Utility. Please help... the place I bought this thing from won't accept refunds...only exchanges, and I've already exchanged it once! SimpleTech is no help...no drivers, or firmware updates to be seen. The support guy merely says to keep formatting it.

I just believe in backing up and punting, so to speak, when all else has failed.
If one partition works, then that would at least prove that the drive and Mac are working together and correctly.

FV2 and booting from an external drive

Hi,
When Lion came out I decided to enable filevault as I take my laptop everywhere.
Periodically I take a full SuperDuper backup of my hard drive just in case the worst happens.
I have read that its best to remove the FileVault protection before entertaining an upgrade so I have removed FV and took another full superduper backup.
Part of my upgrade plan is to test the backup by booting my MBP from the external drive so that I know I can get back to my old machine but I am finding that I can reboot my MBP and select the backup drive from the bootable selection and I get the apple logo and the spinning cog but it doesnt go any further.
I think this has happened since enabling FV as I have never had an issue before booting from an external drive.
I have formatted the drive and started a fresh SuperDuper backup and this hasnt made a difference either.
Any help would be appreciated.
Thanks
Gavin

They all are formatted Extended and with Guid partition map. So I am good that way. I will have to experiment I suppose. Thanks for your response.

Booting Windows on Intel Mac from an external Firewire/USB hard disk?

Is it possible to boot an Intel iMac from an external hard disk - in target disk mode etc., without having to install Boot Camp?
I have a spare drive with installed XP on it and I need to find out what is on the drive before re-formatting. However, I only have my mac in which to do so. The extra disk will be used in an external firewire/USB 2.0 caddy. I have researched some methods, but they are all very long winded and require a PC or the creation of a Windows partition on my start-up disk using Boot Camp.

"Is it possible to boot an Intel iMac from an external hard disk - in target disk mode etc., without having to install Boot Camp?"
No.

Cannot boot my mini from CD/DVD or external firewire drive

The problem I face is simple: I cannot boot my mini from CD/DVD or external firewire drive.
When I boot with option key down, I see the Mac OSX boot and a ghost Windows from an early BootCamp installation, removed long ago (I now use Parallels).
I tried disconnecting everything but keyboard and mouse, to no avail.
I tried resetting PRAM and NVRAM.
I tried disconnecting the mini from everything and waiting one night.
I tried erasing the disk from another Mac when booting the mini as FireWire drive.
And still, the mini refuses to boot from the original CD, or any external drive.
Anyone has an idea whether it is software or hardware ?
Could it be a consequence of the early Boot Camp install and then removal ? Is there a way to reverse this ?
Any help or hint will be appreciated.
Best regards
JC
Intel mini early 2006 Mac OS X (10.4.10) 2gb RAM, core duo

Hi DaddyPaycheck,
Thanks for your message. Indeed, I failed to mention the problem from the Startup Disk Preference point of view.
Bootable CD and/or external disks also never appear in Startup Disk Prefs.
It indeed sounds like time for a backup (I did that) and a HD erase and reinstall of OSX. But since the CD does not want to boot, I tried installing from another Mac with my mini booted as FireWire drive. And that failed, probably because the master mini I used was a G4 one...
Best regards
JC
