Can I set up a startup disk for another computer?

My mom has an iMac and apparently the internal disk has failed. Starts up with the disk and question mark, and running the Disk Utility can't access or format it.
I was going to get an external disk for her to use as a startup disk and was wondering if I can set it up from my computer then send it to her to use with hers. I have an iBook G4 and it would be much easier for me to connect the new drive to my computer, install Mac OS X on it, set up accounts, then install updates. I have DSL and she has dialup, so downloading updates on her system literally takes all night.
I guess I'm wondering if the installer gears the system to work with the hardware it's being run on, or if it doesn't really matter.
Thanks for any input.
Dan

Dan:
Welcome to Apple Discussions.
If your Mom's computer supports Firewire, and meets the minimum system requirements for Tiger or the minimum system requirements for Panther depending on which system you plan to install, it should be fine. In terms of the legality, I am not sure if having the system installed on an external HDD runs afoul of the Software License Agreement which statesThis License allows you to install and use one copy of the Apple Software on a single computer at a time. This License does not allow the Apple Software to exist on more than one computer at a time...On the other hand if you Mom has the install disk and just can't get it on the internal HDD, there should be no problem.
Please don't hesitate to post back with further questions.
Good luck.

Windows set as Default Startup Disk; How to Escape?

My kids have been using our IMac with Windows for several years now. No problems at all.
But today, they went into system prefs in OSX, and (!!!) selected the Windows partition as the startup disk!
So Windows XP is booted, regardless of our attempts to escape ... (option key, PRAMzap).
How can we get that Imac back on OSX ??
This is an early public beta version of Bootcamp (don't see any 'bootcamp control panel' or icon on bottom right screen).

Thanks for your suggestions - I've now tried those startup methods but (to my endless dismay) the IMac starts up Windows regardless.
It seems like the IMac disregards these startup shortcuts when a Windows partition is selected as startup disk?
To recap, WindowsXP boots even when holding down command-X, or CTL, or T, or Option, or PRAMzap, or Shift.
I'm holding the Option key (yes, wired keyboard) from before powerup and all during the boot.
Also I tried to boot from OSX disk (holding down C-key) but that likewise failed. It then took Windows a much longer to boot (as was also the case when I tried command-X).
Can I, while running Windows, install the bootcamp stuff needed so that I have access to the Mac-disk in the Windows control panels? If so, what should I install?

NetBoot appears in startup disks but clients will not boot to the images

I recently upgraded a 10.6.8 server to 10.7.4 server. I did a clean update but saved all the needed information off of it.
The problem I am having is with Netboot. I have the service enabled and the images are in place again. These are the same images from the old server, so I know they worked at one point in time.
Now I can goto the Startup Disk option and see the disks there, but when I try to Netboot I just get the folder with the question mark.
This is in a school so we do have multiple subnets, however the IP address on the server remained the same, so the helper addresses are still working.
I have tried to create a new netboot image, but I am new to all of this and it didn't work (I blame me not knowing how to make one, so yeah).
I am currently trying to use Deployment Studio (as was suggested here https://discussions.apple.com/thread/3962094?start=0&tstart=0), but I really think there is something wrong with my set up of the server and not the images.
Any help is greatly apprecaited.
Thank you,
Keegan

It is possible that one of underlying services required isn't running or configured properly. Here's a little script I wrote to help diagnose issues like this.

Boot camp no longer on startup disk bless tool unable to set boot disk

iOS 10.6.8 boot camp no longer on startup disk msg says 'bless tool unable to set boot disk'

solved my own problem. a simple restart did the trick.

Help: Premiere is making my startup disk full, but I set everything to go on an external hard drive.

The iMac I am using is for the sole purpose of editing and nothing else. I have no idea what is making my startup disk full, and I can not locate the files that are filling the startup disk except the fact that it is telling me I am running out of space. The startup disk is a 250GB SSD, the second internal drive is 1 TB HDD. All of my premiere and video files are loaded ton a 4TB G-RAID.

Do you have your projects set to use a drive other than startup?
My 3 hard drives to edit AVCHD are configured as...
1 - 320Gig Boot for Win7 64bit Pro and ALL program installs
2 - 320Gig data for Win7 paging swap file and video project files
When I create a project on #2 drive, the various work files follow,
so my boot drive is not used for the media cache folders and files
3 - 1Terabyte data for all video files... input & output files

NetBoot images are not showing up in the Startup Disk window

I have created a few Netboot images, enabled them and placed them in the correct place.
They don't show up in the Startup Disk window.
I have noticed that bootparamd is not running, and that after a while also bootpd disappeared.
Strange, no?
(I started them back up and it didn't make a difference.)

It looks like the NFS exports has separate entries for both:
/Volumes/xxxxx
/Volumes/xxxxx/Library/NetBoot/NetBootSP0
and that's not allowed. You can't separately export a directory and one of its subdirectories on the same file system.
It sounds like maybe the Server Admin tools are confused. If you don't really need /Volumes/xxxxx exported, then I think just deleting that share should fix things up.
If you can't get the tools to straighten things out, you could override all the NFS exports with your own defined in /etc/exports. There's an exports(5) man page that describes the format and creating an /etc/exports file will override anything in NetInfo (10.4 and earlier).
If you want to export both directories, they just need to be listed in the same exports entry, like:
/Volumes/xxxxx /Volumes/xxxxx/Library/NetBoot/NetBootSP0
This causes the "/Volumes/xxxxx" file system to be exported and allows only the directories "/Volumes/xxxxx" and "/Volumes/xxxxx/Library/NetBoot/NetBootSP0" to be mounted.

Using ARD through automator application to set startup disks

I am attempting to create an automator application/workflow that sets the startup disk of a group of remote computers and then restarts the machines. I also need to make sure that it does not pop up on the screen to enter an admin password as my university's policy is that no teachers or students have access to the password.
My current unix command I send to the machines is
do shell script “bless -mount /Volumes/DiskName/ -legacy -setBoot -nextonly” password “yourPassword” with administrator privileges
do shell script “shutdown -r now” password “yourPassword” with administrator privileges
When I send that a dialog box pops up asking for and admin password. Wondering where I am going wrong. Any input would be much appreciated

In ARD use the Manage menu to set startup disk...
You can force a restart and no password is required.

Hold the option key at startup and when you get to the boot panel select your Mac OS drive.

4. Select the external disk's icon from which you want to boot.
5. Click on the arrow button below the icon.

NetRestore doesn't set startup disk

I have set up an disk image and NetInstall using NetRestore Helper, and placed the data (.nbi folder and .dmg file) in what I think is the correct place on the server. The server is running Server 10.5.x, and the image is built with 10.4.11. Using NetRestore from the client works fine until the end of the process where I get the following error: "The target disk could not be found, probably because asr failed to remount it. The restore may have failed."
When I reboot the Mac it comes up with a flashing question mark. If I then boot from a CD or external drive however, I can go and set the startup disk to be the internal drive, and the Mac then boots and has the image installed correctly. What to I need to change to get NetRestore to set the startup disk correctly?

Welcome to iDVD Discussions.
Preview doesn't normally show problems. This could be a media issue. Does the DVD play the same way in your Mac and DVD player?
Suggest you create a disc image and then burn the DVD. File/Save as Disc Image...
http://docs.info.apple.com/article.html?path=iDVD/6.0/en/18.html
http://www.kenstone.net/fcphomepage/image_to_diskstone.html
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

How do I set the Startup Disk to Boot Camp via ARD

All,
I typically use ARD and Set Startup Disk to image and reconfigure our lab computers (http://support.apple.com/kb/HT2789) via a network image, namely DeployStudio. This works well. Now I want to be able to set it to a local disk to boot into Windows 7 which we have setup with Boot Camp. I get nothing but Failed responses. I am hoping it is a matter of what name or format I need to use.
I have tried:
BOOTCAMP
Windows
Windows on BOOTCAMP
None of these work. HELP!
These are iMac 21.5's running 10.6.8. ARD is 3.5.1. Same for clients.

have you considered using Send Unix Command to set boot Volume?
For instance if you have "Macintosh HD" and "Boot Camp". And you wanted to set the boot volume to "Boot Camp". You could try sending the unix command, as root:
bless -mount /Volumes/Boot\ Camp -setBoot
After setting this, if you reboot, the computer should boot to the Boot\ Camp volume. But One the computer boots to windows, getting them to boot back to the mac os x is going to be a whole other story.
FYI if your boot camp volume is labeled "Untitled" then you would send the unix command, as root, bless -mount /Volumes/Untitled -setBoot.

Set Startup Disk script

I am trying to use automator to execute either a UNIX command or apple script to change the startup disk volume on the local computer. My university wants us to allow teachers to change to the backup volume without giving them the admin password. They want me to put on the desktop an automator application that when double clicked will change the startup disk volume and restart the machine without having to type in the admin password.
Thanks Mike

See this script:
A script for restarting the computer using a specified installation of Mac OS X:

Perhaps you could change the permission on the bless command. Do not know.
You could add the user to the sudoers file and grant permission to use bless as a regular user.
For this type of question, you best ask over in the hard core unix forum:
http://discussions.apple.com/forum.jspa?forumID=735
Macintosh-HD -> Applications -> Utilities -> Terminal
/usr/sbin/bless
for cryptic details...
man sudoers
/private/etc/sudoers

Startup disk setting ignored if starting from off iMac

In order to speed up the performance of my system (2008 iMac 2.8 Core 2 Duo - 24 inches running Yosemite (10.10.2), I have tried to start running my system off of a spare SSD in a Firewire 800 Enclosure. Works fine when I start the computer off of a restart, but when I shut down the system and then start it up again, the iMac automatically appears to revert to the slower, internal HD. System preferences always indicates that the external SSD is the start up disk. No problems show up when running disk utility. Any ideas as to how to solve this problem?

That info is held in PRAM, so the first obvious thing to try is zapping it, and you might as well zap NVRAM at the same time. Shut down (not just a re-boot). Start up while holding down the 4 keys: Command, Option, P, R, releasing them when you hear the third 'boing'. Check Sys Prefs > Startup Disk.

How to install an OS on a Mac Pro without using a startup disk

Good Evening... I have purchased an Mac Pro 4,1 without any HDD attached to it and I have no startup disk for the installation an OS... When I do power on the Mac Pro, I get a flashing folder with a question mark in it! How can I be able to add an OS for two HDDs that I would like to install?

No. Boot the MP using the external drive. If you need to prep the drives, then:
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select the hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Once the drive has been prepped just clone your external drive to the internal drive:
Clone using Restore Option of Disk Utility
1. Select the destination volume from the left side list.
2. Click on the Restore tab in the DU main window.
3. Select the destination volume from the left side list and drag
it to the Destination entry field.
4. Select the source volume from the left side list and drag it to
the Source entry field.
5. Double-check you got it right, then click on the Restore button.
Destination means the Internal drive. Source means the External startup drive.
