MS-6728 won't boot from DVD drive?

I have a MS-6728 motherboard with bios v2.5 that won't boot from a bootable DVD disk. Here's what I've tried so far:
- Made sure the DVD drive was the first one in the BIOS boot device list.
- Tried two different DVD drives. One plain DVD drive. The other was a DVD dual layer writer. Both were PATA.
- Booted the DVD from three other machines to confirm it's not the DVD disk. It worked fine on all of them.
- Put the DVD drive from one of the machines that booted it correctly into the MS-6728 machine. That didn't fix the problem.
- Removed all drives except the PATA DVD drive and one SATA hard drive. No luck.
- Booted the MS-6728 machine from a bootable CD. That worked it was a Windows XP Pro install CD.
The DVD is a Debian install DVD BTW. Also I tried it each time by doing the F11 (select boot device) and just letting the BIOS auto detect everything. Each time I see a quick flash of "boot record not found" but I know the DVD is bootable since it worked with three other machines. The DVD was made from a ISO image downloaded from the net. I have booted the machine several times before from CDs.
I'm wondering if the BIOS only supports bootable CDs and not bootable DVDs?
Any ideas would be greatly appreciated.

How many IDE controllers does you board have? If it has more than 2, make sure that the DVD drive is connected to Intel controller and not Promise Controller.

XServe won't boot from any drive, but recognizes them in OS X Installer

I know I have another post here but this is a different issue, and I've already fixed that one thanks to Camelot .
I just received an 2 used xserves for work. One booted into OS X Server fine, so I scrubbed it and reinstalled without issue.
The second however never booted into an install. That is, I never found it on my network when I started it up and when I pushed the power button it would turn off immediately, suggesting that there was no OS on the disk or that the xserve couldn't find it. I didn't have a spare monitor to plug into it (surprisingly) so I just chalked it up to the fact that it was a new disk and hadn't had OS X Server installed on it.
Now I have a spare monitor, I've gone and installed OS X Server on the xserve. It boots from the DVD just fine, runs through the installer, then when it goes to restart, it won't boot from the hard drive that it just installed OS X Server on, it'll just boot back from the DVD unless I pop it out. If I let it boot up without the DVD in it, I'll get the standard Folder with a ?.
At first I thought it was the drive, so I installed OS X Server on another drive. Still wouldn't boot to that drive, so I booted from the DVD and repaired the disks in Disk Utility. Still nothing. I booted to DVD again and when I went to Startup Disk, it actually did show my disks with their respective OS X Server installs.
When I boot the machine holding alt/option, the system doesn't show my drives, only the DVD if it's in the slot.
I figured ok, this has to be the drives, so I swapped them with those of the identical xserve in the rack below, but my top xserve wouldn't boot from those drives either. Somewhat expectedly however, the bottom xserve would boot the drives that I took out of the first one.
Now I'm just stumped. Any ideas?
PS, drives are unlocked.

Reset the SMC, and reset the LOM.
I'm running the EFI diagnostic tool now. Firmware and disk I/O path came to mind, let's just hope it's not a major hardware issue

Not booting from DVD drive | Flashing Question mark and face folder SOS!

Hey there! I am hoping one of you folks can help.
I noticed my iMac running really slow.
I could not find my OS disks, so I bought OS X Leopard
When I tried to boot from DVD it would flash the question/face folder for about 30 seconds then reboot normal. (I was able to install the OS. Just can't boot from the disk in order to run disk utility)
Time got away from me and now my system is REALLY slow...
I went and bought Disk Warrior
Same issue, only my drive spits out that disk. (I can run and burn other disks)
I won't discuss my failed attempts at getting help from the Apple store and by having the geniuses (not) call me. I would rather not pay an arm and a leg to have an approved repair center run the disk utility for me. I've already spent $169 on the OS and $100 on Disk Warrior... PLEASE HELP

I think you are going in a totally wrong direction. Your profile indicates you have Leopard (10.5.X) however I don't believe that what you recently purchased. I think you purchased Snow Leopard (10.6.X), these are two totally different OS's! Unless you got extremely lucky and found someone selling 10.5.x then naturally you would have the problem you did trying to boot from it. My advice is:
1. Look to see what version of OS X you are running (click the Apple in the upper left of this screen and then choose About this Mac) then cross check what version of the OS you recently purchased.
2. If you are running 10.5.x then you will need to call Apple and purchase replacement discs for a nominal charge. Once received you should be able to boot from that disc and run Disk Utility from it.
3. If you are running 10.6.x then re post (with an updated profile) so we can determine what the next step is.
It seems like you don't know what you are doing and in an effort to save money you are probably going to spend more than taking your machine to an Apple Authorized Service Provider.

Roger

Hey,
No, I'm not running Snow Leopard. Running Leopard. 10.5.8
I'm guessing the problem is either with my computer itself, or perhaps the DVD drive. Hard to tell. Maybe even something corrupt in my software?
My problem is:
I desperately need to run a disk utility of some sort, however am not able to make my computer use my OS disk or Disk warrior as a startup disk (either by holding down C, or by assigning it in System Utilities.)
I was hoping someone might have a tip, or trick to get my machine to use one of these disks as the startup disk.
Thanks!

Mac Mini won't boot from dvd

I just picked up a used Mac Mini and the previous owner didn't wipe the hard drive. He did include the original install disks in the package, though. I inserted the install disk & it says that OS X Tiger can't be installed on the mini (currently it is running Snow Leopard 10.6.8). I tried to boot from DVD but if I hold down the c key, nothing happens and it boots to the HD like normal. If I hold down the option key, the only boot option shown is the HD. I don't get any request for a password, so this mini doesn't appear to have a firmware password set. The DVD drive appears to be functioning fine since it can read the DVD - I just can't boot from it. If I use the Startup disk utility the only option shown once again is the HD. I even tried upgrading to Mavericks, but get an error message that it can't be installed on this mini (I checked the requirements and this machine meets them - running 10.6.8, at least 2 Gig ram, 1.83 GHz Core 2 duo, 60 Gigs free space on the drive.......
I want to do a clean install but am at a loss on how to do so. Any suggestions?

I inserted the install disk & it says that OS X Tiger can't be installed on the mini (currently it is running Snow Leopard 10.6.8).
You can't install an older version of OS X on top of a newer version. You would have to erase the disk first.
I tried to boot from DVD but if I hold down the c key, nothing happens and it boots to the HD like normal.
Make sure you're using disk# 1 of 2 of the two gray disk set., and that you hold the C key down for enough time, the boot process from the DVD is much slower than from a hard drive. However, since you have Snow Leopard installed now, there is no point in trying to install Tiger, unless he didn't give you his Admin password; you wouldn't be able to add yourself as a new user or delete his user name without knowing the admin password.
If you did get Tiger installed, then you would have to buy a copy of Snow Leopard on DVD.
I checked the requirements and this machine meets them - running 10.6.8, at least 2 Gig ram, 1.83 GHz Core 2 duo, 60 Gigs free space on the drive.......
Those aren't the complete requirements. It has to be an Early 2009 MacMini, Model Identifier number 3.1, to be compatible with Mavericks. Click on the Apple Menu's, "About This Mac," More Information, then System Report, to locate that information.

My 27" iMac Freezes, Won't boot from DVD

My iMac has started to freeze up every few minutes. Every so often, it becomes unresponsive; the mouse cursor still moves (sometimes it turns into a beach ball), but I can't click or type anything. Whenever this happens, the hard drive begins to churn as if it's reading or writing something big. This usually lasts only about thirty seconds to a minute, but it's happening with frustrating regularity.
I've been trying to troubleshoot this for a few days, now. I'll walk you through the steps I've tried so far.
I ran a check on the hard drive with Disk Utility. This came back with a message about the files/directories not matching up with their expected counts. The solution it suggested was to boot from a Snow Leopard disc and let Disk Utility run a Repair Disk while the startup drive is not mounted. It was at this point that I realized that I couldn't boot from the dvd. Whether holding 'C' or 'Option', when it tries to boot from the disc, it gets to the Apple logo and then hangs.
I kept researching and found a workaround; boot into Single User Mode and perform fsck, which fixed the Disk Utility error, but did not solve the freezes/noises, and I still can't boot from the dvd.
Any ideas?

Thank you for your prompt response.
Well, I'm not sure if I explained it clearly. Holding the Option key does indeed bring up a list of bootable devices. The problem arises when control is passed to the Snow Leopard disc. The Apple logo flashes, I can hear the optical drive being accessed, but then it locks up.
I should also clarify that it's not the disc that came with the iMac. I just moved and can't find the original disc, so I borrowed my neighbor's (which came from a Macbook he bought after mine (which I bought last year)). I am under the impression that Macs can't boot from discs that are older than the version of OS X that they shipped with. I wouldn't think that's the issue, here, as his came out later than mine, but I've still got a lot to learn about life in the Appleverse.
My data should be safe--I've got an up to date Time Machine backup on an external drive. The performance issues aside, I'm really looking to understand the underlying problem(s) here.
So, one option is that the RAM might be bad. I can test that by swapping out each DIMM and checking if the problem is resolved. One thing I don't understand, though, is why bad RAM would manifest as the hard drive being accessed. Is there a definitive way to test the logic board, as there is for testing RAM?
Also, I keep thinking of other little syptoms which may or may not be related.
Recap of Symptoms:
Magic Mouse occasionally loses its magic (right click, multitouch, etc.) and needs to be turned off and on.
Free disk space fluctuates by as much as eight gigs (without my intervention).
System stalls (accompanied by HD access sounds) multiple times per hour.
Can't boot from dvds (though, this could be a version problem).
**Fixed: Disk Utility Verify Disk error.
I do understand that this might be a hardware error, and I certainly know how much trouble that sort of thing is to find/fix. I'm definitely willing to open the case and swap out DIMMs and drives, but not until I've exhausted my software solution options. *crosses fingers*

Won't boot from dvd

So my PB 15 won't boot. It gets to the Gray apple screen, hangs up, then gives me a blue screen with a mouse arrow. I tried to boot with the dvd-hold down the c key. No luck, it won't boot from the dvd. I tried to choose a startup disk manually (hold down option key) but I get e screen with a lock and a password box. When I type in my PW-I get nothing.
I am a little feaked-I ned to pull te data down to another machine if I can't get it to boot, but it won't even boot from the dvd.
any ideas? I'm pretty desperate.

The open firmware password can be reset reset and changed by any administrator user, as designated in the Accounts preferences, via physical access to the inside of the computer, or when the computer is started up in Mac OS 9.
Follow these steps:
1. Open the Open Firmware Password application. Note, For Mac OS X v10.4.x, you must use the updated version that can be copied from the software installation disc (located at /Applications/Utilities/ on the disc).
2. Click the icon to authenticate. Enter an administrator username and password when prompted.
3. Click Change.
4. Click to select the checkbox for "Require password to change Open Firmware settings".
5. Type your password in the Password and Verify fields.
6. Click OK. A confirmation appears.
7. Click lock icon to prevent further changes.
8. Choose Quit from the application menu.

IMac G5 won't boot from CD drive, Please Help

My iMac G5 won't boot from the CD drive. There is no operating system on the hard drive so I want to install a fresh copy of Leopard. I have tried a couple different methods, but I keep getting the same end result. The first method I tried was booting from the CD drive by holding the C key during start up. The Leopard disc was automatically ejected after about 20-30 seconds. The second method I tried was booting the iMac to the "question mark file screen," which is when I inserted the Leopard disc. Usually on other Mac computers, this is when the computer will show the Apple logo and prompt you with the installation process. Not this iMac, it just ejects the disc shortly after I insert it. I'm not sure if it's the CD drive that is having the issue, the hard drive, or something else.
If you have any ideas, they would be greatly appreciated!
Thank you,
Chris

Where did you get the CD from?
If it is from another Mac, it is probably specific to the hardware in that Mac and is not capable of boot your iMac.

S10-2 Won't boot from hard drive

I have an S10-2 2957 that won't boot from the internal hard drive. The one key function doesn’t work either. After the splash comes up and the BIOS runs all that is displayed is a flashing cursor. If I boot from an external source (USB CD) I can see the hard drive and all files are intact. I have tried removing the battery and power supply, holding the power key for 30 seconds before powering the unit back up to no avail. I’m thinking that either the boot sector is corrupt or the first partition is not active. Any ideas?
Solved!
Go to Solution.

press f8 to load when you see lenovo logo at start-up, and select safe mode. post back the results.

Won't boot from USB Drive

I am trying to replace my internal drive. I got a WD Scorpio from OWC and formatted and installed OS 10.6. But when I boot from the drive I get the panic screen.
The drive otherwise behaves normally. I can see the files, etc.
Also, strangely, the drive is only recognizable as bootable from the right USB port. That doesn't really make any sense to me.
Please help! The OWC folks have sent me multiple drives and have really tried to get this working, but I have the same result each time. Anyone out there have a solution?
Thanks.

Try prepping the drive this way:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition 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 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 can take up to several hours depending upon the drive size.

New Unibody MBP won't boot from DVD or external drive, just loops

Hey
We bought a new Unibody MBP on Monday, and loaned it to our CTO for a presentation. Having got it back from him now I wanted to nuke the installation and put a fresh copy of leopard on it, so I dropped the DVD in the drive, powered down, and booted holding the "C" key.
I get the chime, screen lights up, thinks for a bit, and if you use your imagination you can almost hear the DVD spin up. Then the screen goes black, lights up, chime, thinks a bit, goes black, lights up, chime and so on
I've tried booting from an external bootable clone I created with CCC (firewire external HDD), and same symptoms.
I even tried swapping in a hard drive that I know has a working bootable copy of Leopard on it, and then all I get is the eternal cycle, without pressing any keys on startup.
I also tried holding down the Option (Alt) key on boot to get the boot device selector. This correctly identifies the various boot devices - the DVD, on-board HDD and external firewire drive (if connected), and lets you select them, tries to boot, thinks, black screen, screen lights up, chime, repeat cycle endlessly until extremely frustrated.
Is there a known cure for this or am I doomed to take the thing back to the Apple store on Monday?
Thanks
Konrad

That is not the reason it didn't work. Here is the actual clarity:
*A retail Leopard DVD should be able to boot a new Macbook Pro unibody.*
So you are saying even if the driver for the controller on which the DVD drive sits is not available in the Leopard DVD you are using because the hardware was not manufactured at the time the Leopard release on the DVD was made, the OS should magically just boot? How is that possible? Unibody MacBook Pros have entirely NEW AHCI chipset - for which there won't be any drivers on the older Leopard DVD and as such the DVD wont be detected once the OS on the DVD loads. In cases where the chipset used is same (as in previous generations of MBP) it will boot.
The key difference here is that if you used an older version, some new hardware may not be supported - however, the computer *should still boot from the DVD*, which is the subject of this discussion.
The OP said that his computer boots from the DVD that came with the computer - just not with the old retail Leopard DVD. Also - what should happen if the new hardware happens to be the controller on which the DVD drive is sitting? How will it be able to read the DVD? What about the graphics card? If the drivers on the old leopard disk do not recognize the new graphics card - how is the OS going to display on screen?
On my way home, I stopped at a Mac store and asked them to test this. They successfully booted a new Macbook Pro unibody from an older Leopard DVD. And this is why Apple is replacing my computer, because it is a hardware issue, not a software one.
Again - you fail to understand that whether or not the old DVD boots on a new machine all depends on how much hardware has changed and what hardware has changed. It may boot on some generation of machine because the basic chipset and graphics did not change or were handled generically by the drivers on the older DVD but it may totally refuse to boot on new gen machine which has totally different / incompatible hardware.
So your claim that any old Leopard DVD must continue to boot on any new machine is not really technically explainable.

BRAND NEW LENOVO K300 5316 1BU (WON'T BOOT FROM DVD SUPERJULTI DRIVE/CD-WRITER

Would appreciate info from the Lenovo Community as to what might be the problem and a fix.
I just received my new Lenovo K300 5316 1BU. As one of the first tasks I made a Lenovo Repair Disc.
To test my disc I rebooted my computer with disc in drive. During reboot I pressed F12 to get to the proper menu.
I chose the cd/dvd drive as the first boot option. It showed that the drive was recognized stating Boot Priority but then went directly into my Windows 7 deskop.
I called Tech Support and tried everything with them with the same results.
They instructed me to do a complete System Restore to see if that corrects the problem.
I have not done this yet since I will do a backup of my present setup, not to loose all my hard work and time setting up all my programs and settings.
Before I do a complete system restore I would appreciate any comments or suggestions from the community regarding this situation.
Do you also believe that doing a full system restore will help or should I send this computer back?
I do find it hard to believe that a computer less than a week old would have this problem with the DVD Supermulti Drive /CD writer.
If I still have no success after a full restore or a resolve from the Lenovo IdeaCentre Community then I will return this computer back to TigerDirect.
To conclude I would like to mention the following regarding this brand new Lenovo K300 5316 1BU top of the line desktop computer.
One of the reasons I purchased this particular desktop was because of the Lenovo Windows 7 ENHANCED operating system that Lenovo has been advertising so much.
To my surprise and disappointment, this BRAND NEW Lenovo Windows 7 Home Premium 64bit does not have the Enhance version, it is Windows 7 Home Premium 64bit only.
Apparently, Lenovo is making some with Enhanced and some without.
Finally, another reason I purchased the 1BU version is because it has a TV Tuner.
To my surprise again, the TV Tuner card in this model does not have an FM Tuner, which almost all TV Tuner Cards have. So, as a result, no FM Radio with Windows 7 Media Center.
Thank you for taking the time to read this long post, but thought it was important to share with the community.
Comments and Help will be most appreciated.

Moderator note; e-mail address removed to stop the spambots getting it

What brand DVD drive did you install? Some third-party drives won't boot by holding down the C key at startup, because they lack the Apple/OEM drive's ROM programming. I recently installed a Memorex (manufactured by LG) DVD burner in a B&W G3, which is recognized by Toast and (with PatchBurn) the iApps. The compatibility problem occurs when selecting a CD/DVD as the startup disk using the Startup Disk Preferences/control panel or by holding down the C key during the restart. In either case, the drive ejects the disk during the POST, so that I have to immediately close the tray and hold down the C key again, to persuade it to boot from the disk. Is this similar to what you're experiencing?

LCD/Santa Rosa systems won't boot from external drives or DVDs

A critical issue with supporting the LED MacBook Pro systems is that to boot from (or install OS to) any external FW Hard Drives MUST be partitioned with the GUID Partition Table option, not the older Apple Partition Map.
This also seems to impact utilities like Disc Warrior and Tech Tool Pro -- the lastest versions of these will not boot either of the two LED MacBook Pro 15" models that I've tested. (This is confirmed on the utilities websites.)
In short, to boot from an external drive it apparently must be formatted with the GUID option (I have no un-partitioned external drives to test). And to boot from a utility CD/DVD -- I haven't found any discs other than the included Apple Software Restore DVD's that will boot these systems.
All models Mac OS X (10.4.9) Corporate support

I'm looking at 4 external FW HD's sitting on my desk
next to our second LCD MacBkPro. These drive can,
and have, booted EVERY INTEL MAC IN THE COMPANY --
with the single exception of the LCD Macs.
I'm looking for hard facts here, not theory. Yes, a
hard drive partitioned with GUID will boot earlier
Intel macs -- but IT WASN'T REQUIRED.
Those of you in theory-land can ask yourselves why
Alsoft's Disk Warrior and Micromat's Tech Tool Pro
CD/DVDs can boot every Intel mac made --- with the
single exception of the LCD Macs. Go to their
websites if you don't believe me...
Back to the topic -- the LCD MacBookPro models
require the GUID partitioning, and seem to require
something else for booting that Alsoft and Micromat
are working on right now. But for those of us who
make our living supporting macs, working with these
machines may require reformatting of external drives
(you can't reformat just one partition) and not allow
use of our standard CD/DVD bootable utility discs.
You know, you might get a bit more help if your tone was a bit more pleasant. I hope it works out for you.
One might argue that those who "make their living supporting macs" might have done better to keep themselves abreast of what was happening in "Theoryland" some time earlier - say 15 months ago when people first realised that intel macs used the GUID partition system. Then they wouldn't be too surprised. I'm not, neither are the others here who are wading in to HELP.

C55-A won't boot from DVD or USB thumb drive.

I'm trying to boot Linux Mint from a DVD or USB stick and this laptop just says that the media failed when trying to initilize either the DVD or USB stick. I've disabled secure boot in the bios thinking it was UEFI problem but it still won't boot. These discs and usb sticks work in other computers.
Not sure where to go from here, any advice would be much appreciated.

Try this.
In the UEFI, go to the Advanced tab, enter "System Configuration" and set the Boot Mode to "CSM Boot."
Always tell us which Satellite C55-A you have when you post here. There is a label on the bottom.
