Booting from external SATA firewire800 hardware RAID array

Just a quick post to update on a new toy and how it's being used.
Recently obtained a hardware RAID array which contains 5 drives at 250 GB each. Currenly setup as RAID 5, providing 1TB of storage.
After formating via DISk image I did a drive restore from my normal boot disk to the new array.
I changed the startup options to boot from the array.
So basically I am running my system from this new device.....I may later reconfig the array to 0+1 with a floating spare.
Cost of the box was 500. New and unused off ebay.

Can I boot from a SATA drive? What if it's RAID?

I'm planning on getting the MSI 875P Neo FIS2R 800FSB motherboard. I'm also planning on getting ONE SATA hard drive. Can I boot from the SATA drive? Do I HAVE to set up it as a RAID drive? Can you boot from RAID drives? RAID and SATA confuse me a little. Anyone care to help?

I'm using the MSI 865PE Neo2 board and I'm having this problem. It probably has an easy solution, but this is my first build, so I'm not sure exactly what to do.
MSI 865PE Neo 2 Mobo
2.4b P4
Seagate SATA 80GB HDD
Panasonic FDD
Lite-On DVDROM
It took me a little bit of experimenting, but I got the BIOS to recogonize the DVD & HDD. It seems every time I got it to recognize one, the other disappeared. Anyway, like I said, BIOS recognizes all 3 now.
I go to install XP and it says I need to install the drivers from a floppy (after I had previously hit F6). Well, where do I get the drivers? I have a CDROM that came with the mobo but I don't know where to find the drivers for the SATA controller on it. ???
Can someone help me by directing me to a download and/or the file names that I need to transfer to floppy for Win XP installation? I would appreciate it. Thanks.

How to prevent boot from external devices?

Hello,
Does anyone know how I could disable my imac's boot from external devices (firewire/USB disks etc.) like it can be done on PC hardware by changing BIOS options? Also, how can you password protect your machine pre-boot? I believe both issues are important to protect from unauthorized access (know the "evil maid attack"?)
Many thanks,
Georgios

There is a firmware password feature
http://support.apple.com/kb/HT1352
but there is an ominous Warning below the Summary. It basically sets the hardware so that a password (not the same as you user account password) is needed when you start up the Mac and nothing much can be done without it.
At the most basic level, if you turn off +Automatic Login+ in System Preferences Accounts pane, a login window will appear when you start up. If a different account (or a different drive) is used to start up your iMac, your user account home folder will not be accessible directly. However, the data is not encrypted in any way, so a determined hacker would be able to access your data.
If you want to encrypt your user account home folder, you can use the File Vault feature which is set up in System Preferences Security pane FileVault tab.

Tiger won't boot from external firewire

Installed 10.4.3 DVD on clean external firewire (Extended/Journaled). Before I installed Tiger, I ran updates, and repaired permissions. Everything looked good to me.
I'm keeping Panther on main system drive for now - so from System Preferences>Startup Disk>the external tiger drive appears and I select it. Then I select restart and the promt confirms that the computer will restart with 10.4.3. Looks good so far.
After restart, I'm looking at the desktop, guess what? It's 10.3.9, not 10.4.3. How could that be?
Also, when I restart and hold down the Option key for Startup Manager options - the firewire drive does not appear as an option.
So Tiger appears in System Preferences>Startup Disc as an option, but the option doesn't actually work, and that drive does not appear at all in (Option key) startup manager.
I'm Indexing the firewire drive now (OMG is that slow or what!), but I'm not expecting this to make any difference. I'm stumped. What am I overlooking? Please advise.
Muchas Gracias

R MacCool,
"What if I manually drag and drop the 4 folders (from the Tiger DVD) onto a second internal SATA drive without partitioning the drive first? Will I be able to boot off an internal SATA drive like that? When I installed Tiger on the external firewire I see that 4 folders are there - I could drag them from that drive onto the second internal drive. Does that work?"
No, this does not work. MacOS X consists of more then 20,000 invisible files, most of them somehow connected and referencing each other.
MacOS X DOES boot from external firewire drives, both hard disks and DVD drives.
Why don't you just upgrade your current 10.3.9 to Tiger using this procedure: 10.4 Tiger Upgrade: Decision tree+Checklist?
"Why does Tiger seem to install correctly, then System Pref>Startup Disc recognizes it, but then after selecting 10.4.3 it restarts into 10.3.9?"
I am not a technician, but it could be that the firmware is the primary source for connectivity. After MacOS X has booted the internal firewire drivers might take over and "overrule" the firmware (this is why you can see it in the startup disk preference pane) but at boot-time it exclusively depends on the firmware. This theory might be completely wrong though.

27-in iMac Late 2009 boots from external HD only

We have a late 2009 27-in iMac running Mavericks (10.9.5) with 8Gb ram and a 1-yr old Seagate 1TB hard drive. We recently erased the drive and performed a Time Machine backup of the entire system from a MacBook Air. The iMac was working fine until yesterday.
On startup, we get the chime, then a gray screen, and eventually the missing startup disk icon (blinking folder with question mark). The iMac will startup and run from an external drive using a clean install of Mavericks but will not startup any other way.
It will not respond to holding the option key, or D, or R. I have pulled and reseated the RAM, and zapped the PRAM (command-P + option-R). I have attempted to startup in Safe mode, and Single User mode, which also do not work.
I'd like to run diagnostics / apple hardware test, but holding the D (or option-D) won't work.
Any ideas what else I can try? or Is it simply the HD has failed?
I'd really like to know if there's anything else wrong (hardware test) before opening it up and replacing the HD again. The nearest Apple Store is 90 miles away.
Thanks!

OOn iMac press and hold "Option" immediatly after Poweron. This should prompt to you disk selection for boot.
othereways you can boot from external device (always in the samewa) and start boot camp to select boot. keep in mind that command+operation+p+r reset the nvram and this also delete boot option to start from other devices.
Let me know If this is your problem

Booting from external device causes kernal panic

Yosemite won't Boot from External SSD with Firewire Connection

Seeking help, I boot from external SSD drives from my 2010 iMac. I recently installed Yosemite on an External SSD with a firewire connection and all went well with the installation and first boot. After completing set up and restarting my iMac Yosemite will no longer boot from the firewire connection it will boot to the loading bar and then get the dreaded Goest Buster Emblem, if I swap out the SSD to USB connection it boots normally. I have 6 SSD Drives with Mavericks and Lion installed on that will boot from the Firewire Connection. Any suggestions ?

Additionally when testing while the SSD is connected to a USB Connection and booted if I attach any firewire device they are not recognized or connected to the operating system.

I do not know about Disk Warrior but if you have a compatible OSX on an external HDD you certainly can boot the MBP. Use startup manager:

How to boot from external Hardisk where sap is installed

Hi friends,
I have an External Hardisk where SAP is installed in it i.e., Win 2003 on C drive & SAP on D drive.
In my laptop Win XP is there, but I am trying to boot with External Hardisk where Win 2003 is installed.
I am selecting to boot from External Hardisk where Win 2003 is installed but it shows the Win 2003 booting screen and the next moment screen becomes black.
So can anyone help me How to boot from Hardisk.
Thanks

Hi,
You can not boot OS from USB devices in Windows.
Create the separate drive on your existing disc and install windows on that drive and use ur USB disc for installing SAP.
Hope it'll help u....

Boot from external Firewire Drive-cannot repair or optimize internal drive.

Hi all
Connected my new 300 GB Seagate External Firewire Hard Drive today.
Installed Tiger from DVD. Updated to 10.4.3.
Installed Tech Tool Pro 4. Updated to 4.1.1.
Booted from External Firewire Drive.
Disk Utility cannot Verify or Repair internal drive. Does not say or do anything.
Tech Tool Pro cannot repair volume or optimize. Says, "Cannot Unmount Volume."
Is there a fix for this?
Thank you for the help!
Jeff
eMac 800 nVidia. Mac OS X (10.4.3) 160 GB Internal HD. Pioneer Superdrive. 1 GB RAM.

Hi
I did name the new external completely different from the internal.
After booting from the external Firewire Hard Drive, I tried running Disk Utility and Tech Tool Pro from both drives. No matter which drive I run the Utilities from the same things happen every time...
Nothing happens when trying to use Disk Utility to Verify Volume on internal eMac Drive.
Tech Tool Pro says, "Cannot unmount volume" when trying to check Volume or Optimize internal drive.

Cannot boot from external HD

I have an external HD which my iMac backups my system daily. I use CCC for that and it has run fine so far. I never had any problem booting from that HD either by using Option/Alt during booting or thru using System Preferences.
Not now anymore. The iMac (late 2013, 27", FusionDrive) refuses to boot from it.
In System Preferences I can see the external HD as a bootable device. However the iMac still uses the internal drive.
When using Option/Alt I only see the internal drive and the restore partition.
I have made a (new) full backup to the external HD and CCC says it "blessed" the HD. But not possible to boot from. Further I did things like resetting Pram, resetting SMC. But does not help.
So next I installed the iMac from scratch (meaning starting the Internet restore and then do a full erase). But still the iMac will not boot from external.
I have connected the external HD to another Mac (Mini) and there it boots flawlessly. So to me there must be a problem with the iMac. But what can I do, this is a serious problem since I now have a backup but this can not fully be used?

- The issue is only if you want to boot from a USB3 external device.
- There are other ports on your machine that you can boot from, refer: Startup Manager: How to select a startup volume
- The ASC is not where Apple make announcements, Refer to their main website.
- Your question / query / feedback should be referred to : https://ssl.apple.com/support/feedback/
- If you find from Apple a resolution, post back. We would like to hear !
Cheers

Ibook g3 M2453 boot from external DVD drive

Hi, I'm Simon from Germany.
I have an iBook M2453 Mac OS X and a lot of dvds.
But the iBook has no DVD drive. So I bought an external DVD drive. But no matter what I do during boot (press the C key or alt)
I can not boot from external DVD drive.
Please help me
Thank you.
Simon.
PS: I have translated the text using Google translate

Hi Simon,
the iBook is able to boot from USB, but this is not expected behaviour and not supported by Apple.
http://support.apple.com/kb/TA20554
There are some external enclosures that do the trick.
But only when you press ALT after Power on. (Select a startup volume via the Startup Manager)
External enclosures with Prolific PL-3507 chipset (Firewire/USB Combo)
You will find them on Ebay Germany
I have a Delock IDE>USB 2.0 enclosure for 2,5" HDs
http://www.delock.com/produkte/gruppen/Geh%C3%A4use/Delock_25_external_enclosure _USB20_42365.html?setLanguage=EN
that works also.
Hallo Simon,
das läuft nur mit einigen wenigen externen Gehäusen. Such auf Ebay nach "PL-3507"
und nimm eins mit Firewire und USB Anschlüssen.
Ein Festplattengehäuse von Delock für 2,5" Festplatten ging auch ( Link oben)
Ein Boot ist nur möglich wenn du die ALT Taste nach dem Einschalten drückst und dann über den Startup manager dein Boot volume auswählst.

Booting from external hard drive on intel-based MacBook Pro

Good day everyone. I know similar questions were raised in this community, but I still have some questions.
I have MacBook Pro(late 2011) with OS X 10.7.5 and external hard drive with Ubuntu 13.04, from wich i can boot succefully on my PC. But MacBook Pro will not boot from my external drive, no matter which key/combination i use during restart.
After googling I found some answers to my initial question, how to boot from external hard drive

As I understand I need to format my external hard drive into GUID partition type and this will be enough to be able to boot from it on my mac?
With this new partition type, will I be able to install ubuntu again on my external drive?
Does GUID partition type supports NTFS, ext4 and FAT32, linux swap?(I use ntfs for big files, ext4 as partition for ubuntu and fat32, because i use windows, linux and osx)
Will I be able to boot from my pc from my external drive with this new partition type?
What are downsides, if any, to GPT?
here is info on my e-drive

LowLuster wrote:
The only OS that will boot from an external drive is Mac OS X or maybe Linux. For OS X to be installed on any drive it need to be formatted Mac OS Extended and have GUID partition table.
As for Linux I'm not that familiar with it but again for a Mac to boot it need an EFI partition on the drive and I don't think that is possible with NTFS or FAT32 let alone the native Linux format.
Went to wiki to learn more on efi but found artice on uefi.
Operating system loaders are a class of the UEFI applications. As such, they are stored as files on a file system that can be accessed by the firmware, called EFI System partition (ESP). Supported file systems include FAT32, FAT16 and FAT12, and supported partition table scheme is GPT only. UEFI does not rely on a boot sector, although ESP provides space for it as part of the backwards compatibility.[26]
Here is FAQ on official uefi website.
Can UEFI Secure Boot be adopted and implemented by a variety of operating systems?
UEFI specifications are platform-independent, supporting multiple platforms and architectures. In addition, UEFI specifications are designed to promote cross-functionality, as well as to support broad adoption across multiple operating systems, including Windows as well as Linux-based operating systems. The specifications are robust and can potentially complement—or even advance—other distributions, such as Linux-based distributions.
And here is wiki article on GPT expaining OS support.
It is obvious both uefi and GPT are ok with Linux and file systems such as FAT32, ext4 and NTFS.
I guess there is no much difference(or is that the same thing?) between uefi and efi used in Macs.
In your answer to Stark Industries you said that mac can boot linux from external hard drive, well this is not the info i got of official website and it is still my question, because your answer is very inconclusive and your info is partially incorrect

2010 13" MBP Wont boot from internal. Will boot from external

This is fairly long winded, I will try to be as clear as i can.
Last week my 13" MBP refused to boot after running out of battery during sleep.
I have done the following to the original drive:
Booted from Lion Recovery, repaired, verified, and repaired/verified permissions.
Booted from Snow Leopard DVD, done the above.
Used Disk Utility on another Mac, done the above.
The drive still will not boot from the internal cable.
I can see the drive when attached internally, but cannot do any of the above actions as it is "unable to unmount"
I can boot from the drive if I use a USB external adaptor.
I bought a new hard drive....
I have done all the same on the new HDD with additionaly installing fresh Lion / Snow Leopard to the new drive whilst its in the internal position (Leopard from the DVD originating with my laptop, Lion from Lion Recovery whilst the other drive was on USB) but still having the same problem when it comes to booting - i.e. wont boot from internal. will boot from external USB.
Ideally I would like to end up with a lean install of lion, on the new hdd, booting from inside the laptop.
Please help, this is driving me mad.

I think you have solved your own problem. If you have two different HD's and they both do not work once connected, but do when placed in an external enclosure, then I would think it has something to do with the connection.
Slap the old drive back in the machine, and take it to the genius bar, and have them diagnose it. Hopefully they will have an answer for you. If not, bring the other drive too inside he external enclosure, and show them that it boots via the external.
Then, lay the whammy on them, and tell them that the original drive works inside the enclosure too.
Would be interesting to know what the actual issue is, and the resolution as well...

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.
