Trouble booting off DVD/external drive. wierd boot screen

My new iBook G4 has been working fine by itself.
I have an older external firewire drive and when I try to use that as the startup drive, it seems to boot up fine but the cursor remains frozen in the top left corner. The keyboard seems to work fine. (I haven't been able to get keyboard commands to drive the menus. That's another problem I guess).
I can run the original install disk and I can run the hardware diagnostics on it. All is fine.
Then I tried to reinstall Tiger on the external hard drive using the install DVD that came with our family pack.
When I run the installer on my new iBook G4 and the computer restarts, the screen that comes up after the gray Apple logo and spinning gear is a blue border and white rectangle with graphics showing what look like a two-step process, numbered 1 and 2 at the bottom. The graphic depicts an oval shape with what looks like a cover removed and two AA-type battery icons linked to the graphic. The picture is much the same for each step with differences the communnicate the idea of inserting or replacing. The second step has a small blinking red circle, like a screw head.
I have no control over the arrow cursor in the top-left of my screen. No action I can perform onscreen from the keyboard.
What is this screen?
I tried resetting PRAM, went into Open Firmware to reset NVRAM and all.
No devices are attached and it still does this. I don't use a wireless mouse, which is sort of what the oval shape reminds me of. Given the frozen cursor in both cases, it makes me think there's something going on with the information it's getting about what pointing device is being used.
The DVD runs fine on other computers and is right now completing the installation I was trying to do, using a Powerbook G4.

Thanks. Makes sense. I'll try that. I had checked the drive firmware with the most recent LaCie updater. So I didn't think it was the drive.
I did manage to use the keyboard shortcuts to open the Keyboard Preference Pane while booted off of the external drive. I enjoyed learning how useful it is to type the beginning of search terms (like "trac") into the Search box and use the menu of matches returned to navigate by Mouse to the Trackpad pane, only to be told that the Trackpad Tab wasn't loaded because my iBook doesn't have one (wrong). It had loaded only the Mouse tab.
Learning a few new tidbits today. Thank you very much.

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported. Is this a bug in Mavericks?

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported.
This happens not just with the SSD in my Mac Mini, but with another SSD in my MacBook (both now running Mavericks). So far as I know, all of the kit I am using is in good order (despite the file corruption reports). So I am beginning to wonder if it could be due to a bug in Mavericks? Both SSD drives have been formatted to MacOS Extended (journaled) format. Should I have used a different format, I wonder?
Has anyone else encountered this issue?
Does anyone have a solution?
Or an explanation that might help my investigation of the issue?
Thanks guys,

I understand that the Corsair Force 3 is not one of the SSD drives that are supported on Apple Macs.
I did try downloading and using Trim Enabler, but the error message came up both when it was off and when it was on.
I understand that not everyone thinks Trim Enabler is a good program, though there is a new version out now, so I may give it another try.

MBP upgraded to Mavericks won't boot off of external drive

Now that I have upgraded my MBP to Mavericks I can not longer boot off of extrenal drives like I has in the past. I hold down the option key at boot up and it display the external drive as a bootable option but once clicked....it just hangs.
Has anyone else experienced this?
Thanks,
D

Well, want to rule out drive case,, as those do come up with EVERY new OS, just hit Lion 10.7 forum when it came out, or when 10.6.0 came out 3 yrs ago.
Maybe the power adapter is the weak link.
As I said, and goes back yrs, not a fan of FW/USB/eSATA case from major vendors (LaCie, WD, Seagate etc).
And you could try another case. Be sure to buy a case that lets you swap in your own hard drives though.

Booting Windows Off An External Drive

I have (access to) an Intel Mac Mini which is quite capable of running Window in Boot Camp, although it doesn't currently have Windows installed or Boot Camp set up.
I have a Macbook which runs Windows XP in Boot Camp.
I have an external hard drive that I can use to make a bootable clone of my Windows XP boot camp partition.
Can I use a bootable copy of Windows XP on the external hard drive to boot the Mac Mini, which doesn't have a boot camp partition of its own and hasn't had Boot Camp set up yet?

Oh well. I'm familiar with booting Mac OSX from an external drive; I make occasional bootable backups in CCC and make other backups by creating a disk image clone in Disk Utility; since DU can't make an image of the startup drive, I boot from my previous CCC backups to do it. (It also means I can boot Leopard rather than Tiger on my PowerPC box; I've found Tiger is very slow to identify my USB backup drive, while Leopard mounts it instantly.)
It's a pity Windows doesn't boot of an external drive; I can't install Boot Camp on the machine in question because it's not mine and its owner wouldn't let me. If I could boot off an external drive and not touch its startup disk (which Windows wouldn't be able to see anyway due to lack of HFS+ support), I'd be able to use it.

Can you boot off a usb drive or external hard drive (usb 2.0) on an iMac?

I have an intel iMac that will not boot off of a USB drive with Ubuntu installed (my PC netbook boots off the usb drive fine) or my external hard drive with Ubuntu installed. I heard somewhere that you cannot boot off of usb on iMacs even if they are Intel, but a Genius bar guy told me diffferent. Then why won't it work for me, and how can I make it? Thanks.

I should have been more general in my post - I don't believe any Mac can boot off an external drive with Ubuntu. I could be wrong of course (and if I am, hopefully someone will correct me), but as Mac hardware is so specific that it demands a specific install disk for each build/model/generation, it would be unable to boot with just a "foreign" OS such as Ubuntu installed. As you may know, you can't boot an iMac with an install disk from a different model iMac, Macbook, or any other Mac (unless it is exactly the same build/model), so it doesn't surprise me that it won't boot with Ubuntu.
Edit: and this question begs to be asked: why would you want to boot/use Ubuntu when you have a superb OS to work with already?

How do I boot from an external drive?

I've just Carbon Cloned my 60GB drive to a firewire external drive. I'm about to replace the 60GB with a 160GB drive and the CCC instructions say boot from the external drive I'd just created once the new disk is installed. Then CCC the cloned drive back to the new hard drive.
So, how do I boot from an external drive? Do I have load anything to the new drive? Will the macbook detect the external drive and boot from that? Or what??????
Thanks
Dick

Thanks DWB. Being the rash impetuous guy I am I didn't wait for replies and just switched on the macbook after installing the new disk (which was so easy it was unbelievable - had to go and buy a a little torx bit though) to see what would happen.
Blow me down with a feather if it didn't just boot off the external drive all by itself :-O It did come up with the disk was unverified and I could see it in FINDER and I was prseented with a screen to ERASE/RESTORE etc.
When I went to CCC the external drive back to the new hard drive it didn't give show me the new hard drive so I guessed I'd have to do something to format (?) the hard drive.
I don't know if I did the right thing but I went to disk utilities and chose ERASE in the vague hope it would maybe format the disk in some way.
Seems to work now and the CCC replaced the system perfectly as far as I can see.
Basically very impressive all round. Piece of proverbial to replace the disk and CCC made life so easy.
Thanks again.
Cheers

Can't connect to LAN when booting MBP from external drive?

In an effort to always work in my computer environment, I backup my Mac Pro main drive to an external firewire drive, plug in to my new Macbook Pro 2.9 and option start off this drive. Result is I'm working off the last backup of my main Mac Pro drive so all my apps, stored mail, etc, is alive and well. I merely track any changes and new files and copy them over or use DropBox to get them on to my Main Mac Pro, my main computer.
Problem is, when booting off my external drive running Lion 10.7.5, my MBP's network won't turn on or recognize my home LAN. Then if I restart off just the MBP drive, it does connet to my LAN automatically.
Could the problem be that since my MBP was set up for Mount Lion, that it won't fully work with a drive with a Lion OS on it? I thought perhaps I had to turn on Airport when on my external Lion drive, since I don't have that turned on on my Mac Pro which uses ethernet. Can't figure this one out. The MBP must have airport as I'm on it now but booted off the internal ML OSX drive.
Thx,
Steven

No not at all. You should have access to your LAN from any version of OS X that is set up correctly. It's still using the same hardware and should be loading the same drivers for that hardware and YES you may have to actually turn on the Airport card.

Can I boot from an external drive with a "Virtual CD"

I just purchased a Hitachi LifeStudio external hard drive for use as my Time Machine backup. When I plugged it in to my MacBook running 10.6.4, I realized that it had one of those "Virtual CDs" that contained the manufacturers crapware, similar to Western Digital's MyWare or whatever its called. It shows up in disk utility as an actual separate disk and not just another partition that can be wiped.
I reformatted the drive using GUID and and created 3 HFS+ Journaled partitions. One was going to be for the 10.6 installer, one for the 10.6 boot, and one for my time machine backup. I restored a 10.6 install dvd disk image I created using disk utility to the 10.6 installer partition (with erase destination checked) then option booted my mac and the partitions did not show up. The only thing I could see was my internal hard drive.
I have done this many times before and it has always worked so Im trying to figure out what Im doing wrong. The only thing I can think of is that the "Virtual CD" that Hitachi put on this external drive is stopping the Mac from seeing the bootable partitions I created. I even went into system preferences>startup disk and blessed the 10.6 install partition. That didn't work either, the computer just booted to my internal drive.
So my questions are. Is it because of this "Virtual CD" that I can't boot from my external drive? If so, is there a way around it? I already searched their web site and emailed their tech support asking for a firmware update to remove the virtual cd.
Thanks in advance.

Yes, it's a known issue. You've already referred to the issue with WD systems. WD has a long list of products that are either not compatible with Macs or won't boot a Mac.
There are practically no problems with bare drives, but once installed in an enclosure there is no guarantee that the package will function as a bootable device. This is especially the case if the manufacturer uses some sort of "virtual" scheme intended for using the device as a sort of one button backup device.
External drives don't have to specifically say anything about being Mac bootable or compatible. It's up to the consumer to verify compatibility and usability.

Imac G4 700 - can I boot off a firewire drive?

The internal hard drive in my iMac G4 has died. I'm not afraid of working inside computers, but from what I've read online, it appears to be a major pain in the *** to replace the hard drive on this generation of iMacs.
Is it possible to boot off an external firewire hard drive instead of trying to replace the internal one? I would probably just buy a firewire enclosure off newegg and stick a standard IDE hard drive in it. Will this work?

Hello and Welcome to Apple Discussions.
I would
also like to say that some cheap Firewire chipsets are unreliable for booting. I could never get the Prolific 3507 chipset in one of my Firewire drives to boot. Go for an Oxford chipset if you can. There's loads of choice here:

Booting Windows from external drive

Hi all. I recently got an external Firewire 400 drive for backups, and it's just occurred to me that I could possibly run Windows off of it and reclaim some 60GB of internal hard drive space. I would like to know if this is possible. Yes, I know that Windows supposedly cannot boot from an external drive, but I have read reports of people booting it off of USB drives, and wonder if a similar tact can be tried for Firewire for greater I/O speed. I also know that OS X can be booted from Firewire, so it seems it should be possibly for Windows.
My guess as to how to do this would be to. . .
- use dd to do a bit-by-bit copy of the Windows partition on my internal drive to a partition on the external drive
- modify the boot.ini on the external so that it points to the correct location
- modify a .cfg file to load Firewire drivers earlier in the boot process (?)
The first step is trivial, and the second will be easy since the Firewire drive will appear in the same place unless I have another external or CD attached. What I'm not sure how to go about doing is the third - which .cfg? I can probably figure out the drivers otherwise.
Finally: has anyone else done something like this? If so, links/hints? Thanks.

i recommend looking into rEFIt:
I've looked at rEFIt before (because I really didn't want to go through all that hacking), but I think the problem still exists: Windows XP does not support EFI (and neither will Vista), so there's still the problem of USB/Firewire drivers loading at boot time. From
http://forums.macrumors.com/archive/index.php/t-224050.html
some people got rEFIt on the external drive, and that helped to dual boot on that drive, but it still required hacking the Windows CD (it's the registry, that I think goes into the installation itself, that's hacked). It's a Window's problem.
you should be able to do this using esata external
drives with a esata express card for native speeds.
If the expresscard includes drivers that support booting, it may work (hence the mention of the Nitro AV card). I know that not all cards do, and I haven't heard anyone had success with it. But, it would be cool if someone decides to get such cards and try ; )

Is it possilbe to install Windows 7 in an external drive using Boot Camp

Hi,
Is it possilbe to install Windows 7 in an external drive using Boot Camp? If yes, can you someone show me or direct me where I can find more info?
Thanks a lot

You're welcome anytime.
Microsoft doesn't make it easy sometimes
As for the harddisk it surely is possible.

Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation it gives me an input/output error and stops. Any tips?

Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation and after having selected both my destination and source drives, the operation begins but soon fails due to input/output error. If I try to create an image of the drive it gives me the same error message. Any help would be much appreciated.

Disk Utility only creates a image of the drive, so it's no help getting exactly what you want, which is your files. If the file structure is messed up or the drive is failing then it's no help.
If you have a external boot drive and you can't access the internal non-booting drive though the typical Finder and windows to transfer your files via drag and drop methods, then you need to install Data Rescue on the external boot drive and it will do as best as it can to recover your files. (works on non-encrypted/non-Filevaulted drives only)

Booting From An External Drive in OS 9.2?

I have a G4 with a bad internal ROM drive. I am currently running OS 9.2.
I would like to upgrade to OS 10.
I have an Iomega USB 2.0 external drive connected to my computer via the USB port in the back.
How can I boot from the disk in this external drive?
I tried holding "option"- it only found my regular hard drive.
I tried holding "cmd-opt-shift-del" but my mac got very confused and blinked a ? at me.
How can I boot from the external drive so I can upgrade?
Thanks

Welcome to Apple Discussions!
Mac OS X will not boot from USB drives on a PowerPC.
You need a Firewire optical drive to boot, and an AGP PowerMac G4 at that to boot Mac OS X. To identify your PowerMac G4, see this article:
http://docs.info.apple.com/article.html?artnum=58418
Once you've identified it, boot the machine into Mac OS 9 on the hard drive and make sure your firmware is up to date:
http://docs.info.apple.com/article.html?artnum=86117
And then you'll be able to install Mac OS X. Follow these precautions on my FAQ before doing so:
http://www.macmaps.com/upgradefaq.html
If it turns out you have a PCI PowerMac G4, you'll have to replace the optical drive internally to boot Mac OS X or Mac OS 9.
Also make sure your clock battery is under 4 years old before attempting to upgrade the firmware. It is a 3.6 V 1/2 AA battery you can buy from Radio Shack item 23-026.

How Do I Always Boot From An External Drive

I successfully installed Mac OS X 10.4.8 on an external hard drive. It boots successfully into OS X, but only if you press option on boot and select the drive or if you boot from the drive inside my Mac Mini and go to startup disk and select the external. Is there any way to just always boot from the external drive without doing anything? Thanks in advance for all of your help.
Mac Mini PowerPC Mac OS X (10.4.8)

If booting from a cold start doesn't work but restarting after selecting the drive does work, then most likely the drive isn't ready when the Mac is doing the cold boot.
Try turning the drive on several seconds before turning on the Mac.
