Boot MacBook Pro From External USB HD

I have a 20 GB external USB HD. This drive started life as a replacement drive for my 3rd generation iPod. I could not get the drive to work in the iPod so I bought a USB enclosure for it and planned on using it as an emergency boot drive. (I could not find a reasonably priced FireWire enclosure for this 1.8" Toshiba HD.) The drive enclosure is USB 2 and has the small triangular shaped USB port, like you would find on a camera. I have installed Mac OS 10.4.6 and some diagnostic apps on the drive. However, I cannot seem to boot from the external drive. Any thoughts or help would be appreciated.

I don't believe this is possible with USB.
The official name for this is "Firewire Booting", which shows that FW, rather than the hard drive, is a necessary part of external booting. Same with Firewire Target Mode.

Can't Boot Macbook Pro from CD, Tried 3 known Working Discs, Can boot Ubuntu

I am trying to boot my macbook pro with the Snow Leopard CDROM. Regardless of how I attempt to boot I get the white screen with the Apple logo and nothing else. I've let it sit there for 45 minutes at one point. There is no apparent disc activity at this point.
I've tried holding C while booting. I've trying runing the Installer while booted of the internal disk, selecting Utilities, and then Restart and same problem.
I've tried 3 known working copies of Snow Leopard our helpdesk uses on a daily bases. None of them have any scratches and are quickly mounted and easily redeable in my mac when booted from internal disk.
I can boot fine from an Ubuntu 11 64-bit CDROM.
I've tried reseting the PRAM multiple times. I've tried booting into firmware mode but that doesn't seem to work. (cmd-option-O-F)
Very frustrating.

Is this the gray disc that came with the machine, or is it a retail disc? If it's retail, did the machine come with SL installed? If so, you can't use a retail disc.

Booting Windows XP from external USB disk drive

I'm trying to get to some legacy applications on my old Windows XP hard drive. Is it possible to boot my iMac G5 iSight to an external USB hard drive which has an NTFS partition and Windows XP on it?

Hi Cobyflier;
No. That is not possible.

Boot macbook pro from imac backup

I am running OS 10.8.5 on iMac (9.1) and clone the startup drive. Is there any problem expected if I use this clone as startup for my MacbookPro? I have 4GB memory in the Laptop.

Thanks. Have found some apps that will not open and when I rebooted the iMac from the clone(with new mail and other documents that had accrued) I found I could not get APP STORE to open! Maybe some other problems with apps on two different computers using the clone between them. May have to sync everything thru a cloud rather than a portable drive?

Satellite L20-100 can be booted from external USB hard drive?

I recently bought Toshiba Satellite L20-100 and I wonder if:
1. is there any possibility to boot this machine from external usb hard drive?
2. it is possible to attach another internal hard drive?
Supposing that the both answers above are 'no', how can I solve the following problem: I need hdd space, I need to boot 3 separate Wxp Operating Systems onto the same machine (Toshiba Satellite L20-100).

Booting from external USB HD - "No" would be the official, mcrsoft sponsored, answer. However, it is possible. Not easy but it can be done. I've seen it done with my own eyes and there are guides how to do this. Just look for it with search engine. But if you have enough disk space you better do what was suggested here - create 3 partitions and use boot manager.

Holy Moly!
Your'e answer is really for those kids with no experience in a terminal.
The command line is only for pro users and should no be used by any DAU. Therefore no problem at all with "rm -rf" if you have changed into the correct directory first.
One suggetion is adding these lines to your "~/.profile"
TERM=xterm-color
# colors for misc things
export TERM=xterm-color
export GREP_OPTIONS='--color=auto' GREP_COLOR='1;32'
export CLICOLOR=1
# Set colors
export LS_COLORS='di=1;36:fi=0:ln=4;34:pi=5:so=4;5:bd=5:cd=5:or=4;91:mi=4;92:ex=35:*.r b=90'
alias rm="rm -i"
alias cp="cp -i"
PS1="(\u) \[\033[01;31m\]\h\[\033[01;34m\] [\w]# \[\033[00m\]"
Than do a
# source .profile
at the terminal prompt in order to active the settings immediatelly.
Now the "rm" command will always ask before deleting any file or folder.
Unfortunately if you like to delete a folder containing other folders with several files inside you will go mad!
One possible intermediate solution is
# unalias rm; rm -rf ./System/Library/Caches/com.apple.*; alias rm="rm -i"
But as mentioned before, if you have "sweaty fingers" while typing in Unix commands you should better stay away from the terminal.

How do I move pictures from my MacBook Pro to a USB/External Hard drive?

I can't figure out how to trasfer pictures and files from my MacBook Pro to my USB hard drive. Help please?

We could use a little more information, are you trying to move from a folder to an external drive? Or are you moving from IPhoto.
Either way should be able to select the pictures you want and drag them to your external.
If you have not used the drive before you may need to format the external drive with Disk Utility. You will need to choose a catalog method and what you choose should depend on if you plan to use a Mac only, or Mac and PC.

hm... Is there any chance of making the bootable usb file and send it by dropbox or something like that? than put it in a pen drive and connect to the mac??
Sending by Dropbox where, To who, to what computer? As your does not start up.
You need to take at least the OS disc to a work Mac computer and create DMG from the OS install disc then restore that DMG to USB thumb drive. Then you can boot the computer from that thumb drive and install the OS. That is if your hard drive is functioning correctly.
Then you can use the App disc in the external CD/DVD drive to load up all the included Applications that come with your version of OS X.

Possible to boot MacBook Pro Core i7 from an APM FireWire drive?

Hi everyone,
is there a way to boot the current MacBook Pros from a FireWire drive which uses Apple Partition Map instead of GUID? I’m asking, because I use a FW drive with lots of partitions containing service tools, etc. This needs to be used on older PPC Macs, too. So until now I just used it with APM, because this also worked fine with Intel Core (2) Duo Macs. The problem is that it no longer seems to work with the current Macs.
Is there a way to fix this or will I need to carry 2 external drives from now on?
Thanks
Björn

Thanks, I assumed something like that. While trying to boot 10.6.3 from my APM drive it would halt at the grey  screen without the spinning, so I thought booting off APM drives is no longer possible. I know that it’s not officially supported for Intel Macs, but it always worked. Maybe I will just wait if 10.6.4 automagically solves this.
I was playing with the USB stick option too, but as long as I can keep everything on 1 drive I will do that. Currently there is everything from 10.3.9 to 10.6.3 on it.
Thanks
Björn

15" i7 Macbook Pro from early 2011.takes the mac laptop two or three tries to boot successfully. It would turn on, show gray screen, shut down, turn on again, show gray screen, shutdown, and then turn on, show gray screen, before it can finally get

Hello All,
I have a 15" i7 Macbook Pro from early 2011. The past few weeks, it has been getting increasingly difficult to get on my computer. It takes the mac laptop two or three tries to boot successfully. It would turn on, show gray screen, shut down, turn on again, show gray screen, shutdown, and then turn on, show gray screen, before it can finally get to the dark gray log-in screen. Even when I finally get logged in to start working, thinking it would be okay now, it shuts down randomly.
I've ruled out the possibility of a software problem because I've just done a clean re-install of Mac OS X Mavericks on my computer just yesterday.
I did upgrade the RAM recently, about a month and a half ago, from 4GB to 16GB, I went to the apple store four days after that upgrade to have them do a hardware test, and clean the inside of my laptop, which helped with previous heat issues. When they did the hardware test, the hardware was all registered as fine from their system.
I've tried resetting the SMC, PRAM, and doing the internet recovery hardware test, but to no avail. I thought I could at least find out what parts needed to be replaced from the hardware test but it seems that when the hardware test is almost finished, the computer just shuts down, So I am unable to see the results.
My computer is also having battery issues, under battery condition, it says "replace now," parts have been ordered, waiting for arrival. But if the battery health is low, it should still boot up fine, it would just hold a significantly less charge.
Could this be a hard drive issue?
Has anyone had similar symptoms and how was it resolved?
Does anyone know what I can do to alleviate this issue?
I haven't had time to take it to Apple because I'm currently taking a 21 credit semester academically. I'm an art and design student so my computer is basically the bane of my existence. Help! Any constructive advice is welcomed!
Thank you so much for your input!
-Christina C.

How can I get Time Machine to back up an external hard drive (iPhotos) that is attached to airport extreme base station. Note: Time machine is usb to macbook pro and external drive with iphotos is usb to airport extreme base station. Help please. Thanks!

Once you have the drive connected to your Mac, click System Preferences (gear icon) on the dock
Click Time Machine
Click Options
Be default, the hard drive will be Excluded from backups. Click the drive to highlight it, then click the "-" (minus) button at the bottom of the list to remove the drive from Excluded items.
The drive will be backed up on the next Time Machine pass
Everything above assumes that the hard drive has been formatted in Mac OS Extended (Journaled) as Time Machine will only backup drives in that format.

I am switching to Apple macbook pro from Windows laptop. Is Apple compatible with Microsoft Office? How can I transport from Windows to Mac? What I have saved on external hardrives, will I be able to open it on Mac?

I am switching to Apple macbook pro from Windows laptop. Is Apple compatible with Microsoft Office? How can I transport from Windows to Mac? What I have saved on external hardrives, will I be able to open it on Mac?

Is Apple compatible with Microsoft Office?
Any computer is compatible as long as it can read and write Office files. But for perfect (or at least near perfect) compatibility, you would want to purchase Office 2011 for Mac.
How can I transport from Windows to Mac?
You can't directly transport any installation of Windows. All PC's come with a machine specific version of Windows intended for that PC. They don't have all of the hardware drivers the retail disks cover.
If you want Windows on your Mac, you would first purchase a full version copy (NOT an upgrade disk) of Windows 7 or 8. Those are the only supported versions on newer Macs. You install it through the supplied Boot Camp utility that comes with the Mac to create a new partition for Windows, and then install the retail copy of Windows you purchased.
The reason only these versions of Windows are supported is the same basic reason as a machine specific version of Windows for a PC. Apple only includes the necessary Mac hardware drivers for Win 7 or 8 on new Macs.
Once Windows is installed, you could then install the version of Office for Windows you already own. The nuisance of a Boot Camp partition is that you have to physically boot to either Windows or OS X, so you can only use the apps of the OS you're in at the time. To use both at once, you'd have to use virtual machine software (Parallels, VMware, VirtualBox) and then install Windows within that. Then you'd be able to run Windows inside of OS X and have access to both at the same time.

I cannot find videos (not movies) that i have transferred to my macbook pro from an external hard drive, these files used to be on my windows PC. Photos and a few of the videos came over but i am missing the majority of the videos. Help please!!! I have tried omnidisksweeper with no success in finding them.
in my Usage it says i have over 40 gb of movies when i only have about 9gb which i can see using spotlight search. i really hope the other amount is my missing videos! these are videos of my kids as babies.

Read this post and do the migration again, putting the library in a portable shape first if necessary.

i tried transferring my iphoto library from my old macbook onto my new macbook pro (via external hard drive), but when i open the new iphoto, it seems to have transferred ALL images ever used on my old macbook. so i tried to just delete all those images so i could try a different approach to transferring, but the new iphoto won't let me do anything and every time i try to delete anything it crashes (since the image amount is so high). please help!!
MacBook Pro, OS X Mountain Lion (10.8.2), iphoto '11, version 9.4.2

To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then launch iPhoto. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.
