Booting from a USB 2.0 flash drive

After reading an article on website MAC OS X Hints on booting from a USB 2.0 flash drive I decided to try it. I used DasBoot to create an OSX system. I then booted in Open Firmware and typed 'devalias' as the instuction said to do but I never got the 'ud' listing that I was supposed to see so I was never able to boot off the drive. I followed all the instuctions then typed mac-boot. When the system restarted it momentarily flashed the folder with the ? on it then proceeded to boot off the internal HD. Anyone else tried to boot off a USB 2.0 drive with an iMac G5 Rev A running 10.4.10 and was successful?

Since you didn't post a reference to the OS X Hints article it's hard to tell what you may have done wrong. When you post a problem you need to provide complete information.
That said you shouldn't have to do anything special except to be sure you properly partition and format the flash device:
Extended Hard Drive Preparation
1. Open Disk Utility.
2. After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Click on the Options button and be sure to select the APM partition scheme then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition only.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume mounts on the Desktop.
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 Options 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 will take 30 minutes to an hour or more depending upon the drive size.
After formatting has completed you can install OS X and then upgrade it to 10.4.10. That should be all you need do. Now open the Startup Disk preference pane, select the icon of the flash drive, then click on the Restart button.

Late 2008 mbp - installed new ssd - trying to boot from snow leopard iso on flash drive - says 'cannot install mac os on this computer'

Hello -
I just installed a new M500 Crucial ssd in my late 2008 mbp - everything was working fine on old hard drive (running snow leopard) but was getting slow and wanted to upgrade - i lost my snow leopard disk when moving from hawaii so i found an iso online - using a flash drive i partitioned the disk and made the bootable image on flash drive - formatted as extended/journaled - switched out the hard drives - plugged in the flash drive - started the comp - held option - install begins to boot - choose language - all is fine - choose english - next step window pops up saying 'cannot install os on this computer' - click on utility but all options are greyed out - disk util is greyed out - only options it gives is to start from backup or restart - real confused here - all help appreciated - thanks in advance and happy new year!

Snow Leopard comes in discs only. The USB drive may be a counterfeit and/or corrupt. There are two options for you:
Get replacement original OSX installation disks from Apple customer service. Have your MBP serial number ready and there is a charge.
Or two, purchase a Snow Leopard disk from the Apple online store:

My compaq cq62-214nr will not boot from a usb flash drive

I have a Compaq CQ62-214 NR Notebook. When I enter the bios boot options screen with F9 there is a blank space where Boot from USB/Flash Drive should be. If I enter the bios setup and move usb flash drive up to the first option above Notebook hardrive and Internal CD/DVD Rom ,save the changes to the BIOS then Reboot. Enter the boot options screen again the blank line moves up to the first choice slot but still is blank. If I press enter over that black option the computer does not boot from the OS I have install on the usb flash drive it just starts its normal windows boot screen. YES I have upgraded the BIOS to the lates version F.37
Can somone tell me what is wrong.

Try booting into the one time boot menu.
Step 1: As soon as you turn on the computer on the hp invent screen keep tapping F9 key.
Step 2: you will get boot otions such as hard drive, optical drive, USb drive
Step 3: You can hit enter on the usb flash drive. Should boot from the os on your flash drive

How do I boot from a USB flash drive?

I have two different Toshiba laptops. In the BIOS settings I only see the following options.
Laptop 1:
CD/DVD
FDD
LAN
HDD1/SSD1
Laptop 2:
HDD1/SSD1
HDD2/SSD2
eSATA HDD
CD/DVD
FDD
LAN
Is it possible to make either computer boot from a USB flash drive?
Thanks in advance for any help,
yeto

FDD (Floppy Disk Drive) equates to USB in my Toshiba laptops. Seems like it's taking some BIOS designers a long time to catch up with the rest of the computer world!

T440 - Problem booting from Win7 USB drive

Dear Forum I have a wonderful new T440 here and am wishing to load Windows 7 x64 from a bootable usb memory stick, which I've always used and works fine on other computers (tested again this morning).However when I try to boot my T440 from this drive, I can bring up the temporary boot menu and see the usb drive in the list, but when I select it (press enter) the screen just flashes and comes back to the temporary boot menu. IT will not accept my memory stick! I tried with another stick with Win7 on , but got the same problem. Interestingly I also have a X240 here and this behaves exactly the same. So I don't think it is the USB Drive and its not the T440. What can I do. Just out of interest I was able to boot from a Windows 8 prepared USB drive... which is great but I don't want to load win8, I need to load win7. help! Thanks

Hey, i just bought a new T440p and i have the same issue with booting from a USB.
Thing is, i already prepared the stick (FAT32), and enabled the secure boot. I read onlinde that with Windows 7 (which I try to install) i shouldnt enable the CSM Support, is that right?
Are there any other things i need to change in order to boot from the USB?
thanks in advance

So what you want is to be able to boot from OS X and retrieve your files
Create a data recovery/undelete external boot drive
Of course if it's not booting up, it's easier to fix in place

...so I am trying to boot from a USB recovery drive but when I select it nothing happens it just goes to the restore options
"Recovery HD" is a partition on your boot drive which you option or commnad r key held at boot time to get into and then repair the Macintish HD partition.
If you have this on a external USB thumb drive, then that's all it is, no OS X, programs or files.
If your talking a USB external drive, it has to be a OS X bootable clone made with Carbon Copy Cloner or SuperDuper and the option key held at boot time gives you that boot option.
Most commonly used backup methods
So what your saying is you have a external clone and by holding the option key down at boot all you get is it directly going to Recovery HD?
There is no Startup Manager option to choose what to boot from?
This could mean Apple changed something, or your external bootable clone isn't one, or the wrong software used so it's not being recognized by Startup Manager as a bootable option.
What did you use to make the external OS X USB bootable drive?

SA30-414 boot from the USB floppy drive

Hi All!
I'm tryin to get my my satellite A30-414 to boot from the USB floppy drive and enter the dos mode, but all i get is a black screen (without a cursor, of course!!), and then the windows XP logon page directly. Can you tell me whether this model has a boot device menu hotkey?
Also, I may have permanently changed some boot configurations (namely by holding down the F12 at startup and then the F2 key at a later try) with my attempts to get the machine to boot from floppy drive: now even when the floppy drive is not connected i get this awkward black screen and then, after a few seconds, the windows logon page. How can I acceed the setup menu and check?
Thanks in advance for your help!

Thanks to you all for your support!
Now I'll tell how this problem originated. I connected the standard usb fdd with a standard DOS boot disk to which I had added a firmware upgrade for my DVDrom unit. I powered on and held the F12 key down expecting to see the boot device selection menu, instead i got a black screen for a few seconds and then the winXP logon page. At this point i rebooted and held down the F2 key with the same purpose. But the computer went into some kind of hybernation and by pressing the power-on button it shut down.
From that moment on startup I don't see the BIOS POST page anymore: countless seconds of black screen and then the WinXP logon page. The most optimistic explanation to this is that i inadvertently changed the boot order, so it searches for floppy first, and when it doesn't find it then it goes to C:\. Does it sound logical?

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.

I have a 2012 Mini with a fusion drive that won't boot from a usb cloned drive. It came with 10.8.2 pre installed. I have zapped the PRAM and reset the SMC. Any thoughts?

I have a 2012 Mini with a fusion drive that won't boot from a usb cloned drive. It came with 10.8.2 pre installed. I have zapped the PRAM and reset the SMC. Any thoughts?

When I tried using a recently downloaded (from the App store) version of MtLion 10.8.2 (12C60) I could NOT get the new MacMini to install or boot from a USB I had previously made. I was however able to use the Recovery Mode of the MacMini to create a bootable SSD which I had installed. The problem arose when I went back into Recovery DU as it saw the seperate drives (SSD & HD) as a broken Fusion Drive. Interestingly DU from the boot volume had NO issues and reported NO faults. It was the Recovery DU that identified the faulty Fusion Drive configuration. At this point I am definately out of my depth but my speculation is that the Recovery Volume is being used in some fashion to form the method or pattern that DU assigns files to the drives, System Report sees the drives as seperate volumes with all their individual characteristics.
Disk Utility did not make a bootable USB, I don't have or use CCC or Super Duper.
Here is the longer version I've been compiling:
Having bought a late 2012 Mac Mini(6,2) i7 2.66GHZ with the standard 1TB 5400 HD and 4GB of RAM (base model) I immediately decided to install a Mercury Elite 6g 240GB SSD and up the RAM to 16GB. I received both shipments on the same day and had all my new toys in front of me. After following the video advice on OWC’s website for the installation of the second drive I started the mini and formatted the SSD to accept the OS from Recovery on the original HD. This MacMini shipped with 10.8.2 (12C2034) as the OS, the normal build of 10.8.2 is (12C60). Having used Recovery Disk Utility to format the SSD it came back with an error that DU could’t Repair. I went ahead and installed the OS on the SSD and the Mini booted normally from both drives. The issue I encountered with this setup was that iMovie encountered an “unexpected error” and would not save a completed project. I therefore decided to figure the drive issue out because I suspect the new Fusion File Management software didn’t like my configuration with drives that Recovery DU saw as needing to be “fixed”. After spending some time on the phone with both OWC and Apple Support I took the plunge and used Internet Recovery Disk Utility and allowed both drives to be “fixed” after which DU created a Fusion Drive (Logical Drive) that I then ran Repair Disk on and it showed up as a single drive in DU. It works perfectly as described by Apple’s site:
http://support.apple.com/kb/HT5446
Having checked the Link Speed and Negotiated Speed they both show as 6g so I’m pleased not to have lost performance due to it being fuzed to a 3g 5400 drive. The biggest drawback is that Apple’s Fusion Management only allows for 1 additional partition and I would have preferred more than that.
I have sourced some additional information here:

http://blog.fosketts.net/2011/08/05/undocumented-corestorage-commands/
If anyone has a factory Fusion Drive could you please post the Link and Negotiated Speeds of both drives? This information can be found in Apple > About This Mac > More Info… > System Report > Serial ATA and the drives should show up as discrete drives with their info listed separately.

Booting from external USB drive

I was wondering if there is any way to boot from a USB drive that I have? I partitioned the drive, erased it, and its basically ready to go. But I can't install Mac OS X on it because it says that I cannot reboot from the drive.
I know that iBook G4s generally can't boot from a USB devise but is there any way to get around this?

If you're computer is having kernel panics there's a conflict; either software or hardware. 2GB of free space isn't enough but I haven't seen anything that suggests KPs are caused by too little free space. Your computer should start fine with 2GB free. It may have problems after a period of use but it would startup and run.
Try starting in Safe Mode. If successful move some of your files to the external drive and then restart normally. If it KPs again, restart in safe mode and disable all startup items in System Preferences>Accounts>youraccount and restart. If it KPs again go through the linked troubleshooting steps by Dr. Smoke step by step. That's the only way to resole your problem.

Macbook Pro 15" won't boot from ANYTHING :( Can't mount internal drive

Hi there,
I'm new to these forums so please bear with me if I make a faux pas.
A few days ago while watching a movie on my MBP Intel Core 2 Duo 2.5 the beach ball of death appeared and the computer became unresponsive. I restarted to the flashing folder with a question mark.
Tried to boot from the install disk - No joy : Occasionally gets to the language selection screen (after a good 5-8 minute wait) and then instantly and completely freezes. Cursor won't move, caps lock light is unresponsive etc..
Tried to boot from Diskwarrior - Similar to the above. Long wait, boots to the Diskwarrior 'setting up' screen, unresponsive cursor - despite, Diskwarrior seemingly going through the motions (status in text changes, menu bar appears) and then it reports an unexpected error with code 60, 2105 and completely freezes.
Can't boot from a USB flash drive with a clean version of OS X made from my install disk.
Disk won't mount when in target disk mode. However the DVD drive mounts it's contents onto the host machine when it target mode.
I removed the drive last night and placed it in an external enclosure and OS X reports "The disk you've inserted is not recognised et.. "Initialise" "Ignore" "Eject". The drive appears in Disk Utility but all options are greyed out, SMART status says 'not supported' and it's capacity is shown as 0 bytes. The drive registers in the Hardware pane of Diskwarrior but no-where else.
I'm fine with the fact that the drive has failed but could these problems indicate something more serious? I'm concerned that the machine won't boot from any device or media. Is this a symptom of a failed hard drive or could this be a logic board issue?
Any advice would be greatly appreciated!!!!
Thanks all and Happy new Year.
XOXO

You might try a PRAM reset and see if this does any good.
http://support.apple.com/kb/HT1379?viewlocale=en_US
It sounds like the hard drive itself is toast based on how it looks in an enclosure. So you won't be able to boot from it. Possibly after a PRAM reset you could option boot to a disc or to your external drive.
I had the experience of a failed hard drive totally messing up my PowerMacG4, and it took some doing to get it going again. I finally got it going again, and it has been working ever since without issue.
The MBP is a different machine, but having experienced first hand what a dying hard drive could do, I think it's well worth doing any resets you can.
If no joy, make an appointment at the genius bar and ask them if they can run a hardware test from their store feed. If you do have other issues, they should show up then.
If you end up being able to boot to the optical drive, you could try running the extended version of the Apple Hardware test yourself.
Good luck!

Can Satellite L40-139 boot from a USB device?

Hello,
I have a new L40-139. Looking through the BIOS I cannot find an option to boot from a USB device such as a USB HDD or USB flash drive. Could someone confirm if teh L40-139 can boot from USB, and is so how to configure the BIOS for this.
If it cannot does anybody know if there are plans for a BIOS update that would allow this?
I have to admit that while I like the L40, I am disappointed at how limited the BIOS is.
Thanks,
R

Hello
I am not 100% sure but, as far as I know, you can not use USB HDD as first bootable device. USB FDD yes, but with external HDD it will not work.

X1C: Imaging a brand new X1C -- how best to? via Acronis? USB 3.0 or USB 2.0 flash drive?

For a brand new X1C, may i ask what some pointers are might be relevant to imaging?
apparently, USB 3.0 flash drives will not work due both to Windows 7 as well as Acronis not recognizing USB 3.0 for a boot up drive (as USB 3.0 post dates Windows 7 and Acronis).
have y'all been successful with a 32gb USB 2.0 flash drive? any particular brand?
also: how much of your 32gb flash drive was consumed with a brand new image of the X1C please?
Thanks very much in advance.
