Can a G5 boot from ethernet

I'm looking into external backups and, firewire's ability to boot is a big plus.
But gigabit ethernet is a bit quicker and there is a lot more choice. But I've come across a couple of articles which seem to say that power macs that are NetBSD equiped, can boot from a startup volume over ethernet.
Mac help says macs can boot from a netboot disk image on an OSX Server, but doesn't mention whether it HAS to be an OSX Server (well they wouldn't would they).
Anyone know? Anyone done it?

It doesn't have to be a Mac OS X Server, but that makes it much easier.
I just did a little search, found this:

Why can't I boot from the OS X DVD on my Intel iMac?

I'm trying to boot from the Mac OS X Tiger CPU Drop in DVD that came from the Apple Refurb Store with my Intel iMac.
I have tried holding down the C key on start up and it doesn't work. It boots like normal to the hard drive
I have tried using the Start up Manager, but all it can see to boot from is my installed OS X system on the hard drive and my Windows Boot Camp partition.
The CPU Drop in DVD is all that shipped with my machine. Can one even boot with it?
My problem is Photoshop Elements refuses to start up, giving me EXCBADACCESS and KERNINVALIDADDRESS alerts. It crashes every time about half way through starting up. Trashing it's preference folder doesn't fix the problem. In fact, my Preference folder keeps filling up with folders labeled with jibberish names.
I found a discussion thread that I should boot from the original disk that came with the machine and use Disk Utilities, but I can't even boot from the DVD drive.
What step am I missing?
TIA
Kathryn

Hi knittsings!
It's only possible to boot an Intel-based iMac from a grey-labeled DVD, so if you received a black-labeled DVD, someone made a mistake packaging your refurb. The correct DVDs should have been in the smaller box with the User Guide and other small, square documents, along with the mouse and remote. If you find the grey-labeled DVDs in there, just keep the drop-in DVD, they won't need it back since they make them:)
If you don't find them in there, call Apple, or log into your account on the Store page and find your order's link for customer follow-up/issues.

After installing Lion I can't I boot from the Techtools CD.

After installing Lion I can't I boot from the Techtools CD. I have purchased the upgrade for Photoshop CS5 because CS2 does not launch in Lion 10.7.3. However I need to get the serial number for CS2 for the upgrade. I have waited over 30 minutes for the boot but never get more than the Apple logo. Any ideas anyone?

Boot disks can't change when the firmware changes, lock you out.
Techtools obviously uses Linux as a boot OS, so you need a Lion version.

Can Solaris 10 boot from USB devices like USB thumb?

1. Any live CD build for Solaris 10? That's the one which can boot up from CD and run immediately.
No installation requirement.
2. Can Solaris 10 boot from USB devices like USB thumb?

You can find "live" CD and DVD images at OpenSolaris site: www.genunix.org/distributions/belenix_site. This OSolaris version is booted from CD/DVD drive and can be permanently installed on HD drive. Moreover You can find at this site suitable script for USB thumb preparation. However You should remember that the number of read/writes on USB thumb is limited (ca 400 and slightly more in more expensive versions).
Good luck.

Disconnect everything hooked up to the PC except the keyboard, mouse and monitor.
Then use this method to flash the BIOS. It is the safest way to go.
USB Device BIOS Flashing in DOS
DOS Flash (DOSFlash.exe, FlshUefi.cpu) is the DOS-compatible System BIOS flash utility that can be used from a DOS bootable storage device (where "DOS" refers to any of a number of compatible operating systems such as FreeDOS, MS-DOS or DR-DOS). FlshUefi.cpu is the required driver for DOSFlash.exe. To flash the System BIOS from a bootable USB storage device, you will need to copy the contents of the DOS Flash folder to the USB device, boot the PC from the USB device, and execute the DOSFlash application. To see a more complete description of the DOS flash utilities, view DOSFlash.txt located in the DOS Flash folder. This folder also contains the required binary image of the BIOS. The binary image file is named xxx_MMmm.bin where "xxx" is the BIOS family, "MM" is the major version number, and "mm" is the minor version number. This file can be copied to the root directory of any USB removable medium for use with the F10 setup "Flash System ROM" option

The links on this post don't work. I copied the section from the BIOS flashing instructions for the specific section you need.

Can only boot into Windows 7. Can't even boot from Snow Leopard DVD.

I have no idea what prompted this. I don't recall installing any OS updates recently, other than some Windows Live apps in Windows 7.
I have an early 2009 Mac Mini with Snow Leopard, and have Windows 7 64-bit installed in a Boot Camp partition. When I installed Windows 7, I couldn't get the Boot Camp utility to install within Windows (I guess because it's 64-bit) so to switch back and forth between OSes, I just shut down the Mac and restart it with the Option key pressed, and select Mac OS X when I want to return to Mac. This has worked for about a month and a half now (ever since I got Windows 7). Suddenly I have problems.
I first had problems booting into Windows or Mac. I got to the grey screen with the Apple logo, with that spinning "progress" thing going for a while, then it would freeze up and get stuck on the grey screen with the Apple logo. I zapped the PRAM. No help. Then, after disconnecting all external drives (I have several) and extra USB devices, I was able to boot from the DVD install disk and reinstall Snow Leopard on my internal drive. Joy, or so I thought. Then I booted into Windows 7, and after some weirdness getting it to start, it did successfully start and ran just peachy.
Then I turned off the Mac and held down the option key (as usual) to return to Mac OS. But now all that happens is that I get a grey screen for a few seconds, then the Mac boots back into Windows 7, which seems to work fine. (I'm in Windows 7 right now.) I turned on one my external drives (Snow Leopard installed, connected via Firewire 800) in hopes that the Mac would boot into that, but same thing. Ignored and back to Windows 7.
Then I thought I'd boot from the install DVD again by putting it in the drive and holding down the C key as I restart, but the same thing--a grey screen for a few seconds, and then booting right into Windows 7. I can't seem to escape Windows 7! It's a bit disturbing when it won't even recognize the install DVD.
I tried to call Apple Care since I'm within my 90 day support window, but of course they are closed. I'm figuring that I'm going to have to take this into an Apple Store, but thought I'd see if anyone has any ideas. Any advice will be appreciated. Thanks.

According to Apple, Win 7 64bit is supported with Bootcamp 3.0. If bootcamp 3.0 is available; I could not find it anywhere on Apple's website. It appears the most recent version is 2.2. The only place I could find 3.0 is not on Apples website and it's a questionable source so I won't post it here.
It may just be a matter of time before Apple makes it available. I'm not suggesting you wait, however if the install disk can't be used, I'm not too sure where u could go from there. Calling Applecare might work.
If you do a simple google search using the terms 'download bootcamp drivers windows 7' u will see what I was referring too.
Here's what I found from Apple (It doesn't specifically mention 64bit however just win7): http://support.apple.com/kb/HT3920
This is not from Apple, but specifically addresses whether they support win7 64bit: http://www.macnn.com/articles/09/08/31/boot.camp.win.7.64.support/
Here is more info about bootcamp 3.0 and win7: http://www.apple.com/support/bootcamp/

Can no longer boot from DVD or USB HD since installing Win10

5/2/15
I download and installed the latest Win10 last week and popped it on a spare HD I have in the system;
the mistake I made was to leave my SSD which has Win7 on it connected during the install.
Now I’m in a bit of a pickle. When I boot up with the Win10 disk disconnected I get a splash screen that tells me:
A required device isn’t connected or can’t be accessed. It offers me an option to press F9 to boot to another OS and indeed it does boot me into Win7 but insists all my hard drives need a chkdsk. They are fine
So I thought I’d simply boot from a DVD or USN drive and “fix” the Win 7 install.
Lol , it won’t boot from a DVD or the USB HD. If I pull the Sata cable from the SSD containing Win7 it boots right up from either the DVD or the USB HD.
I’d really not like to do a clean install of Win7 on my SSD just to get around this.
When the drive I loaded Win10 is connected it still won’t boot from a DVD but does allow me to boot into 7 or 10.
Yeah, yeah I know I should have installed it in a VM but I didn’t. Any suggestions?

press Windows+R then in the box, msconfig

Can no longer boot from ANY OS disc on MBP

I recently purchased a 15" 2.16ghz Core Duo Macbook Pro. It came with the original 10.4.5 discs. The previous owner installed 10.6 on it using a retail disc, then upgraded to 10.6.6. I had planned on upgrading the original hard drive. However, I cannot get the laptop to boot from the original discs or my own retail 10.6 disc. I've tried a number of different approaches (booting from an external DVD, holding down "C", holding down "option", attempting to mount in on the desktop first, etc.). Either the machine hangs or it ejects the disc (when using the internal drive). Nothing seems to work. Both the internal drive and external drive have been tested and work fine. Is it possible that when upgrading to 10.6.6 a firmware upgrade was done that won't allow the machine to boot from a disc containing an earlier version? I don't know what else could be causing the issue. The laptop has not displayed any other issues. Thanks for any suggestions or explanations.

I don't know how much help I'll be to you. Seems to have a lot of posts lately about not being able to start up from the install disks.
I assume you can still boot up from the internal drive.
When you hold the option key to start, does the screen come up with the option to choose a startup disk and is your Install Disk in when you attempt this?
While booted up normally, does the Install Disk open up with the install OSX menu? If so, does going through the install menu reboot the computer from the CD automatically?
Even if there were a firmware upgrade, seems like you would be able to use the 10.6 Install Disk to boot from.

Why can I not boot from a disc or drive?

In order to repair my HD, I have tried to start from a DVD (a bootable DiscWarrior 4 disc), but when restarting holding down the c-key, the disc drive is not recognized and the iMac starts up as normal and my log-in icon is shown. I have the latest Lion update.
I have also tried to start up from a bootable memory stick which I made after installing Lion, but this does not work either.
I have also tried to start up from a DVD using the option key, but the drive is not given as an alternative. The same happens if I try to start up from the "Startup drive" preferences from the Apple menu - the disc drive is not shown as an alternative even if it contains a bootable disc.
I try to get booted from another bootdrive in order to repair the Harddisc.

Hi, StenErik. If I were you, I would forget about FireWire Target Disk Mode. I'd start the Powerbook from a retail OS X 10.4 installer DVD, open Disk Utility from the Utilities menu, select the hard drive, reformat it as "Mac OS Extended (Journaled)", check the box for installing OS 9 drivers, and then install Tiger. I can't explain why this should make the resulting installation any different from what you have installed now. But it seems to me there must be some detail you've failed to mention and we've failed to think of, and that detail, whatever it is, is much more significant than it seems: significant enough to prevent your Tibook from booting. Therefore, reverting to the most basic installation procedure possible, with as few external variables as possible, seems a useful thing to try. To minimize variables even further, disconnect all peripherals from the PB while reformatting and installing.
As Hardy has suggested, the size of your drive is not the issue. A 120GB drive should be fine.

Can my iMac boot from an external drive?

Once upon a time, I used Disk Utility, running from the DVD to make a copy of my iMac's internal drive. I also tried using Carbon Copy Cloner to do the same thing. But, I have never been able to get the iMac to recognize the external drive as a boot drive. I just wanted to have a backup that would launch when the internal drive tanks... as it will, one day.

Yes. If you did it right then to boot from the clone:
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 clone's disk icon.
5. Click the arrow button on the far right.
To make the clone:
Repair the Hard Drive and Permissions
Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

Can't even boot from install disc

I appear to have a dead hard drive but was hoping to at least boot up from my Snow Leopard installation DVD to check the internal drive. However, this doesn't appear possible. I've held down the option key at startup to see the list of bootable drives but am presented with nothing. (although I can hear the DVD spin)
Curiously, I tried sticking in a hard drive that I know is ok and WAS able to boot from the DVD!
So why would I not be able to boot from DVD with the other faulty hard drive?

I've heard tell of hard drives that were so badly damaged that they prevented the machine from booting at all. I've never seen it myself and have only rarely heard mention of it, but I believe it can happen. Don't ask me why, though.

Yes, Thunderbolt is bootable. Now all we need are some reasonably priced Thunderbolt drives to try it!

Can OS X boot from an external hard drive's partition?

I purchased a 500GB external hard drive in hopes of: 1. creating a bootable backup copy of a freshly installed version of Snow Leopard, and 2. a backup of files which I don't want on my Macbook (ie. school files from 8 years ago).
If I divide the external hard drive into 2 partitions, can OS X still boot from a partition? I heard from somewhere that OS X can only boot a volume, but not a partition...
As usual, thank you for any help you can provide!

Two names for the same thing: partition = volume.

Most external HDs are bootable. But some Western Digitals won't boot a Mac. Their list of which ones should and +should not+ boot: http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/stdadp.php?pfaqid=1787. But note the disclaimer that they don't support it +*at all.+*

Why can't I boot from a USB stick Ideapad Laptop?

Hi
I just bought new Lenovo IdeaPad Y510P and i've got a problem with installation an Windows 7 64x from a bootable stick.
The OS on laptop is FreeDOS and from this level a cannot install the windows os. The DOS system won't boot from usb stick and there's no BIOS so i can't set the boot order.
As i try to run setup.exe from d: drive(which is flash drive) i receive message that i cannot open this file in DOS system.
I prepared the USB stick according to this solution:
1) Open a Command Prompt with Administrator privileges in either Windows 7 Pro or Windows 8 Pro.
2) Insert the target USB boot media device into an available USB port.
3) Type "DiskPart" in the command prompt.
4) Type "List Disk” (make note of the disk number of the target USB drive).
5) Type "Select Disk X”, where X is the target USB drive noted in step 4.
6) Type "Clean”.
7) Type "Create Partition Primary”.
8) Type "format FS=fat32 quick”.
9) Type "Active”.
10) Type "Assign".
11) Type "list volume".
12) Type "Exit".
The error still persist and i can't go any further with win installation. I strongly asking for help and advice.
Team please assist.
Solved!
Go to Solution.

Hello and welcome,
Are you booting in UEFI or legacy mode?
IIRC if you want to boot and install in UEFI mode you need to format your USB stick FAT32 (which you did) and enable CSM support in BIOS.
You should also be using SP1 media. If pre-SP1 some additional file manipulation is required to get the installer to boot in UEFI mode.
Installing Windows 7 in native EFI mode from USB
If you're booting and installing in legacy mode (which I suspect you are if running FreeDOS - just a guess on my part) you need to format that USB flash drive NTFS.
(You don't say, but I also assume you've copied the contents of a Win 7 install ISO or DVD to that flash drive...)
