T430s: boot from an external USB DVD drive

I wanted to change boot sequence to boot from external DVD drive to install Win8. To access the BIOS I hit Enter (empty password I guess) but in the BIOS everything is greyed out: I can't make any changes. What is going on?
Solved!

@kaja69...
As Rich has stated, you have a supervisor password set, and as Jin Li has stated, there is no default password.
For information on the various BIOS-level passwords, please see your T430s Hardware Maintenance Manual (manual pages 36-38).
Per the Community Rules, discussion of passwords is sensitive territory and may risk a thread lock, so please keep that in mind if/as this discussion progresses.

  • Can I install a retail os10.5.6 from an external usb dvd drive?

    Since the internal dvd combo drive does not read double layer dvd, I tried to install the new version from an external usb dvd. The installation starts but when I have to restart the computer goes back to the first screen.

    Apple does not require any particular type of dvd Just says "an external dvd"
    What document are you referring to? The fact that you can read/write with a particular DVD drive does not necessarily mean you can boot from it.
    If you have another Mac available, you can probably "borrow" its DVD drive for your OS installation by using FireWire Target Disk mode.

  • Can I install Leopard from an external USB DVD drive?

    I am trying to install Leopard onto an older PB G4 whose internal drive is shot. I have an external Pioneer USB 2 drive attached, but when the Leopard Installer prompts me to restart, the installer doesn't kick in and the computer restarts into basic OSX. I've tried to choose the Installer DVD via System Preferences "Start-up Disk" pane, but it doesn't show up. The DVD drive does have its own AC power source.
    Any help would be much appreciated! Thanks!

    Mac OS X will only boot PowerPCs with Firewire, not with USB. That's the reason it doesn't work.

  • Installing SL from an external USB  DVD drive

    Hi, folks.
    The DVD drive in my MBP suddenly stopped working awhile back after I updated to 10.5.7 (won't read any disks at all), and I would like to install SL on it using an external Samsung Writemaster TS-H552U with a USB connection (Firewire is not an option with this unit, as the drive casing only offers a USB connection).
    Is this possible, and if so, what I need are step by step instructions on how to do this. Any help would be appreciated.
    Thanks in advance.

    Thanks, Kappy. I'll give that a try, but have one more question before I do:
    Do I have to watch out for any reboots during the upgrade? If so, at what point(s) do they occur, and will I need to use the OPTION key again if it does, or does it just do the upgrade in one shot and reboot normally afterwards?
    Oh, and I've already installed the latest updates for 10.5.8, and will do a disk and permission repair before I start, just to be on the safe side.
    Here's the specs for the Samsung Writemaster TS-H552U:

    Thanks again.
    EDIT: Sorry, but I forgot to ask, how long should the upgrade take?

  • Can you boot from an external USB hard drive? (Neo2 Platinum)

    As I'm tempted to get a 160Gb drive for Linux and AMD64 XP installations.  But obviously it needs to beable to boot from it.
    Thanks

    I read a post recently about booting from a usb memory stick - I assume the principal is the same.  You need to make the usb drive bootable, in the same way that you would make a cd or a diskette bootable. In the example given about a usb memory stick, they suggested copying the contents of a win98 startup disk onto the memory stick.  Then, run 'sys.com' on the drive letter of the usb stick from the startup disk. Then, enable usb legacy support in the bios, and access the boot order to tell it to boot from the usb or legacy, I'm not sure which.
    What you're in essence wanting to do is to copy the xpcd to the usb drive, so the format and files, etc., are the same.  Then, follow with the usb legacy stuff, etc....

  • Cannot boot to Windows disc from external USB DVD drive.

    I have a MacBook Pro 17" Early 2011 8,3. I have tried to use bootcamp to install Windows 7 from a external USB DVD drive. All I get, like many people, is a black screen with a blinking cursor, as if it never makes it to boot. I tried restarting to the OS selection for holding alt, and tried the DVD again, did not work.
    I saw a few posts claiming that this didn't work on some models of Mac because of a EFI problem that would not allow booting from a external USB, which is really stupid because it would seems some models can... And MacBook airs can... Can someone please confirm this for me? Has anyone found a resolution?
    If not, APPLE PLEASE FIX THIS.

    Hi,
    Thanks for the reply. Yes the MBP is currently running Tiger, I want to flatten this with a fresh install of Leopard. I can view the install DVD when in Tiger currently.
    I haven't tried what you have suggested, but I have seen various posts suggesting this approach. I've also seen several posts explain how to create a partition on an external firewire Harddrive and this seems to have worked for various people.
    This would however mean that I didn't really need the external Lacie drive at all, as I've got access to my G5s DVD drive over the network. The more I search on this, the more convinced I am the USB drive was a bad idea.
    Once again thank for the response.

  • Broken cd drive, so can I boot Os X dvd in external usb Dvd drive on iBook

    So there it is:
    My cd/dvd drive on my iBook 1,33 GHz PowerPc G4, 1,5GB DDR SDRAM is broken....
    I want to know if is there some way to format my iBook hard drive and then boot from an external cd/dvd drive to install OS X 10.4 Tiger on it.."????
    Please help
    Thanks

    You first need to boot your computer from the external drive with the Tiger disk. Once the computer is booted you can run disk Utility, format your internal hard drive and install Tiger. I don't know about more recent G4s but older Macs used to be somewhat selective about the brand of drives from which they would boot so there could be issues there.
    Let us know how it goes.

  • BOOT FROM AN EXTERNAL USB DRIVE???

    I know apple has made it clear about booting from an external USB drive
    http://docs.info.apple.com/article.html?artnum=106474
    but I know that there are people who are able to boot from an external drive, does anybody know how to do this?
    It's just that id like to work on final cut studio on an external drive for various reasons:
    1st: my powerbook's HD is small and slow (60gb)
    2nd: my external usb drive is big (160 gb) and fast (7200 RMPS!)
    so a little help would be apreciated
    best regards

    "Actually, USB II is faster than FW 400."
    In theory, probably. In real life Firewire 400 is much faster than USB2, not to speak of Firewire 800:

  • My laptop won't boot form external USB DVD drive

    Hi, I have HP pavillion dv6748us. My internal dvd drive is not recognized, cannot access and not listed in device manager & window explorer. I need to reboot from the external dvd but don't see the option listed in BIOS. Below is the sequence listed in my BIOS. I have recovery disk and would like to know if and how to add external USB DVD DRIVE  into to BIOS.
    Your help is greatly appreicated!
    (1) ATAPI CD/DVD ROM DRIVE
    (2) USB HARD DRIVE
    (3) NOTEBOOK HARD DRIVE
    (4) USB DISKETTE ON KEY
    (5) USB FLOPPY
    (6) NETWORK ADAPTOR

    Have you tried 2? The BIOS may see the DVD drive as a mass storage device and not distinguish between a hard drive and an optical drive.

  • Problems Installing Win7 using External, USB DVD Drive

    I have a mid 2010 15" i7 MBP which I upgraded to from 4GB to 8GB RAM courtesy of OWC.  I recently upgraded the 500GB 7200RPM HD with a 240GB OCZ Vertex 3 and using an OWC Data Doubler, I replaced the DVD SuperDrive with the 500GB Hard Drive.
    I used an External USB DVD Drive to install OS X SL On the SSD without issues. Also, I got all my updates and software installed and working without any problems.
    I've been running great for about 2 weeks now, so I decided to install Windows 7 64bit Ultimate. I ran Boot Camp Assistant and partitioned the 240GB SSD in half 120/120. Everything went fine with creating the partition. I selected to Install from the Win 7 DVD media in the USB DVD drive and rebooted.  I got a grey screen.  I turned the computer off and turned it back on.  Holding down Option, I selected the Install DVD from the Boot Menu.  I then got a screen with the Apple Logo flashing intermittently with a Circle/Cross Hatch.  So I can't get the Windows Install to start to save my life.  I know the External, USB DVD works since I used it to install OS X and I have no problems using it in OS X.  I Know the media works because I tried a test install, without activation in a VMWare Fusion VM. 
    Any suggestions are appreciated?

    So here is the answer.  The Firmware on the MacBook Pro only supports installation of OS X from External Media and will not install operating systems from 3rd Parties.  I tried to install Windows XP, Win7 Ultimate  32 & 64bit, and Ubuntu 11.04 but no success.
    Supposedly, the MacBook Air does support installation of 3rd party operating systems from external media, but I have no way to confirm this.
    I ended up reinstalling the internal DVD drive installing Win 7 and Ubuntu on the SSD.  Using rEFI, I'm able to triple boot all 3 operating systems.  Then removed the drive again and reinstalled the 2nd HD. Everything seems to be working fine.
    I'm looking for someone who has experience in Mac EFI Hacking to see if there is a way to enable booting 3rd Party OSes from external media.  I'm guessing someone could examine the MBA firmware and figure out how to hack that capability into the MBP.

  • HP external USB DVD Drive not recognized by computer.

  • Installing from an external usb cdrom drive

    I am able to boot an external usb cdrom drive but I cannot figure out how to mount that usb cdrom drive to complete the install.
    My boot command is:
    arch-scsi NEEDUSB=auto
    I cannot run loaddisk, as it does not find the usb cdrom, so I cannot load the addon utilities (thus I cannot modprobe usb-storage).
    I can run /arch/setup but when it gets to package selection, I am unable to select the CDROM source. This machine is not on the net, so I cannot do a ftp install.
    Has anyone else installed ARCH using an external USB cdrom drive ?
    Does anyone have any suggestions?

    Thank you Xentac for you help. I looked up the bug report and understand the problem. Now how do I proceed from here?
    Any suggestions on a work around? Should I rebuild the 0.7 beta disk with additions to the initrd? Eventually, I will need to install Arch on about twenty standalone systems. They do not have cdrom's in them, and are not on a network. Sounds like I may have to open up the units and plug a cdrom in for the install
    I was thinking of cloning the disk (i.e. open up unit, take hard drive out, put in another system and clone), but it has been pointed out that doing a basic install is a good way of testing the hardware. It doesn't take very long and we have to do testing of our software anyways.
    I open to suggestions!

  • Problems importing and playing songs from an external cd/dvd drive

    I am having problems importing songs on my PC from an external usb drive. What I have is an external combo usb firewire drive hooked up to my pc with a usb cable. (usb 2.0) When I launch itunes, it sees the cd I have loaded but when I go to import the songs, itunes just pops past each song in a second like each song was just a second in length. Then I have some corrupt file in my itunes library. Itunes gets the cd names and titles from CDDB correctly but can't play the songs or import them. I use this pc solely for playing audio, it is a Pentium 4 2.6 with 1GB of ram with build in usb 2.0 on the motherboard. There is no other software installed on the system other then virus software. When I use Windows Media Player the cd is read perfectly fine. I even play DVDs off the drive with no problems too. This problem in intermittent, with different cds. These are all commercial cds not burnt ones that someone made for me. Any help or suggestions would be appreciated.

    Hi Toonz - I have exactly the same problem when trying to import songs - itunes does recognise the cd drive and names of tracks etc - it just won't play more than one second of each, or import any more. i did run the cd diagnostic check you suggested - results below - don't mean anything to me i'm afraid - any bright ideas?
    this was a christmas present and i haven't managed to put any new music on apart from what was already on our pc, so am v sad and hope you can make it better....

    Does this means that neither HDD nor CD/DVD drive appears in the BIOS boot option?
    Strange what notebook model do you have?
    Did you try to set BIOS to default?
    If not do this (press F9 and save the changes in BIOS)
