Reset Password - System does not boot from DVD

My System: Macbook Pro - 2Ghz Intel Core Duo - OS X - 10.6.8
Hi everyone,
i forgot my password. So i want to boot from install DVD to reset the password. Unfortunately my macbook pro does not boot from DVD (10.6.3).
I press c all the time...but sometimes the macbook pro throws the DVD out...and sometimes nothing happens.
The DVD drive is working fine...
Any other idea?
Thanks in advance.

So when you boot holding option it shows a padlock with a password field? Is that correct?
In that case we're talking about the firmware password, which you can't reset via the install disk. There is only one way to do this, I'm not certain if one is allowed to divulge that information publicly - might want to try googling "reset firmware password"

SunFire V40Z does not boot from DVD - suggestions and Tips?

Hello,
I got 2 SunFire V40Z servers from another datacenter. I got them racked and powered up and configured the Service processor and I can access the Sp remotely as well. I am trying to install Solaris 10 on it, but it seems like the system doesn't boot from the Solaris dvd. The DVD is good because , I used the same dvd for installing several systems before. I checked in the Bios, cdrom is set as first boot device, floppy and hard disk are set as successive boot devices.
I power cycled the systems hoping that it will try to boot from the dvd, but it skips everything and tries to boot from the network!!!, Don't know why? Anyone have any idea about how to start the install process on V40Z.
BTW, this is my first ever attempt to install OS on V40Z, I had worked on lot sol SPARC servers before. Even X4200, X4100 worked fine for me. Any help would be really appreciated.
Thanks.

Reset Printing System does not exist on my computer!!!

I have been trying to get my HP PSC 2175 to print and working with HP support to do this. It just prints out blank pages. The last thing they sent me was to Reset the printing system using the Printer Setup Utility. And they sent me to the below link:
http://docs.info.apple.com/article.html?artnum=301185
For whatever reason, the "Reset Printing System" DOES NOT EXIST on my computer. I actually sent screen captures to show them. The first showed my
version of the Printer Setup Utility (3.0) and the second showed the
Printer Setup Utility menu - with no such option. I am running OS 10.4.4 and have all of the updates. I even opened the Printer Setup Utility holding down the "option" key.
Does anyone know how to reclaim this feature???
thanks
eric

After all of the emails back and forth with HP, I have really only done two things: A complete manual uninstall - which is a royal pain in the butt. That is worse than any uninstall with windows, and way worse than Class MacOS. Then they kept trying to get me to Reset the Printing system - which is what I can't do.
I upgraded to Tiger via a DVD - straight from the box. I had 10.3.x, bought Tiger and upgraded. I have since updated it via the website. I think what I just installed was the combo updater - but I don't think it really did anything as I had already done that.
If there is a better way to go, please let me know. I searched all over Apple's site for just that piece of the printing system, but unlike the old OS, there doesn't seem to be a way to download those components.

After installation of 10.6.5 system does not boot

After I updated my system with the latest release 10.6.5, the system does not boot up at all. It shuts down every time it restarts. All I can do is go into single user mode and then I cannot repair the disk as I always get the error that "The volume Macintosh HD cannot be repaired when it is in use"
Any other suggestions?

It sounds like your friend's DVD is hardware specific to his Mac and will not work in your Mac.
Since you say a safe boot work that generally indicates that the problem is with third party software because the safe boot prevent any of that from starting.

That sounds like a failed logic board or display module on the logic board...either way you need to take it to an Apple store genius bar and have the techs test it to see exactly what has failed. The testing is free so give the techs a chance at diagnosing the problem.

Flat Screen imac iMac won't boot up, will not boot from DVD

My 24" imac flat screen will not boot. I only get a blank gray/white screen. Reset the PRAM and tried to boot from the DVD. I held the C key down when I powered on but the system will not boot from the DVD. If I wait long enough, the DVD will eventually be ejected. I have had HD issues and Disk Warrior indicated that the drive was damaged. Will a dead hard drive cause the system to not boot from the DVD? Is there any way to get the system to boot from my DVD?

Hello PMcDer,
Welcome to Apple Discussions!
By what you are describing you're correct in believing your drive is probably gone. The sad news... if Disk utility can no longer see the drive, your ability to retrieve any data off of it is getting slim.
There are a couple of options for data retrieval.
1. If you still have Apple Care have them fix it. But make sure they know that you do not have a backup.
2. If you do not have Apple Care, have an Authorized Apple Tech replace the drive and make sure that they will give you back the old drive. This may prove to be a challenge. Or you can replace the drive yourself. It is not easy for some but take your time and you'll have no problems. Lots of youtube videos on this as well as on-line tutorials.
3. You could try a Hard Disk Utility program like Disk Warrior to see if it can help, but it's not free.
4. You could pay someone big bucks for Data recovery in order to get the data of the drive for you.
If you decided to do the HDD swap yourself. You could purchase a 3.5" firewire enclosure that you could put your old drive into once you do the swap. Plug it into the iMac and prey that it recognizes it. Then "MAYBE" you could copy the data over to the new drive, but that is a stretch.

System does not boot when PCIe express Card is inserted in system. Using Spartan-6 PCIe Integrated Endpoint Block 1.3

Hi,
I am using Spartan-6 PCIe Endpoint Block core v1.3 and I am using ISE 12.1. I have used the PIO example design,
modified it according to our design.
The core is configured as below:
BAR0 - 8KB, 32-bit, Memory Type
Lanes - x1
Clock - 125 MHz (system clock)
The card is a custom board. When the card is pluged into the system the system does not boots, it hangs.
I have tried debugging using chipscope and monitored trn_lnk_up_n, trn_reset_n and trn_clk. trn_lnk_up_n stays
high (deasserted), trn_reset_n stays low (asserted), trn_clk is low (No clk).
What might be the issue?
Thanks & Regards.

Thanks Gabor, for the response.
I refered couple of answer records like AR# 34873 and AR# 34894, I monitored trn_reset_n, sys_reset_n, clock_locked, PLLLKDET and RESETDONE signals as suggested in AR# 34894.
Status as follows:
SYS_RESET_N = 1 (deasserted)
TRN_RESET_N = 0 (asserted)
CLOCK_LOCKED = 0 (deasserted)
PLLLKDET = 0 (deasserted)
RESETDONE = 0 (deasserted)
which means the transceiver PLL frequency is not within the predetermined tolerance. Is this problem related to the PCIe Jitter Attenuator I am using on the board to derive 125MHz from 100MHz system Clock.
Thanks & Regards

System does not boot during Hyper V installation

Hi -
I was trying to install Hyper V on my Windows 8.1 professional edition, 64 bit OS. The installation was through ISO downloaded through MSDN. During installation I had to hard boot my system through switch off. Now my system does not boot correctly and during
boot it flashes a message "The last windows installation did not complete please install the setup". Does this mean that my existing 8.1 OS has crashed ? how can i come out of this and recover my data ?
My hardware configuration is :
i7 processor, 16GB RAM, intel graphics Card, windows 8.1 professional 64 bit OS.

Hi RahuIM,
You can try to enter safe mode then copy your personal data to the data volume then reinstall the system.

Satellite P840/016 does not boot from CD or DVD

Using F2 enabled the BIOS to boot from optical drive, saved and re-started. Finds the bootable CD created from the same laptop using the repair disc from Windows 7 recovery but does not boot.
Tried Ubuntu DVD which works as boot disk on all other laptops - still does not boot.
Changed the setting in BIOS to non-secure - same problem.

Thanks - tried this pressing F12. Message appears on the screen to press any key to boot from DVD. Key pressed, the DVD is read and then delay with blank screen. The laptop goes back to start screen and than goes to boot from the HDD. Also tried making USB as bootable. Pressed F12 and selected USB as boot device. Reads the USB and after a period of time boots from HDD.
Checked DVD driver - it is the latest.
Operating system is Windows 8 pro.
RAM is 8GB, processor is I7 and HDD is 1 TB. Laptop is only 3 weeks old

New system does not boot properly

I just set up a new system with:
a MS-6728 Neo2 FIS2R Mobo,
1gb Geil PC-3500 RAM (2x512),
2.6C proc.
2 Maxtor 120gb IDE drives RAID 0 with the onboard promise controller.
Lite-On DVD burner
ATI radeon 9800 video card
Enermax 300 watt power supply with:
3.3v - 28amp
5v - 30amp
12v 22amp
170watt total 3.3/5 combined
My problem is that my system NEVER boots up normally. It always freezes in the bios startup. The D-bracket stops at almost every possible combination of led's, which according to the manual the problems were: Testing RTC, Initialize Video interface, Testing memory, Initializing floppy controller, Memory detection, Decompressing bios to ram, possibly more. Sometimes I also just get beeping, either a continuous beep or 8 beeps. A few times it would display the bios startup screen, but halfway down would be gibberish characters and would be locked up. When I then turn the computer off then on again, the bios is reset at least somewhat(i know because I usually disable the full screen image on startup) and says memory timings are too tight, and I have the choice to enter bios or hit any key to automatically fix things. If I hit any key it will boot up ok. However when I restart/turn off the computer, the next time it again does not boot. I tried upping the ram voltages from 2.5-2.9v, and that seems to stay that way in the bios, even when it resets itself. Everything else is set to auto/slow. If I try to manually adjust the memory timings, even to the slowest possible settings, it does not boot, and I must turn it on/off a few times till the bios resets again, with the boot process stopping at one of the possiblilitys mentioned above. Using the info tab on speedfan, I got the memory info, and it displayed the voltage at 2.5v, not sure what that means but it is strange.
What I have already attempted:
I sent back the ram and got a new set, which hasn't changed anything. The first time the other ram failed memtest, this time it passed(for about 2 hrs). So I don't think its the ram.
I borrowed an antec truepower 430w powersupply, which had no effect.
I went back to bios version 1.3 from 1.9, which also seems to have no effect.
I was hoping to overclock the system a bit and enable performance mode etc etc, but now I'll be happy to just not have to go through a song and dance everytime I restart the computer. This is only the second computer I have built from scratch, and the first with raid, but that seemed to all go ok. Please help me diagnose the problem!

I too am having problems with my system.
865PE Neo2-FIS2R
2 Maxtor 120GB S-ATA drives, RAID 0, Promise
2 512MB Geil Ultra CL2-3-3-6
HP CD-RW
What IDE settings are you using?
E.g...Native? P-ATA Only...all of those settings
For me...sometimes XP will install and boot...but eventually system is unstable and XP crashes and corrupts itself...Event Manager errors different each time
Someone mentioned problems with Maxtor and AMI BIOS...anything I should keep in mind?
Sorry about all the different questions. I'm sure exactly where my problem lies. MSI thinks it may be my memory AND/OR on-board IDE controller since I can't get the on-board Intel RAID setup to consistently "see" and setup my RAID drives...even when it has worked...XP doesn't like the Intel configured RAID drives. Also tried just one S-ATA drive through on-board Intel and Promise. Next I will try a plain old IDE Hard Drive...no S-ATA...and make sure my memory passes memtest86+ testing.
Any other gems you can offer for this config??? Thanks.

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

Not booting from DVD

Hi,
I have an issue with my macbook pro and booting from DVD.
When I try to boot from the DVD it starts reading and after a few minutes I hear the driver stops and only a gray screen with the apple logo in the screen .
I have tried two snow leopard disk and the original disk that came with the macbook pro.
I can boot into the operating system , repair permissions , verify disk and disk utility does not find any problem .
I also tried with a usb dvd and the same symptom, after a minute it stops reading the dvd .
Do you have any Idea what can be the problem ?
Thanks

I seem to be having the same problem. How long should it take to boot from the DVD? We have inserted the original DVD that came with the machine, and I can hear the machine reading from it, but it's been 10 mins and no boot up.
The install DVD is v. 10.6.3 and the current version of the OS on the MacBook is 10.6.6
Also, please can somebody indicate how to create a bootable DVD, and if I start up from that, can I then insert the 10.6.3 disc to run DiskFirstAid or equivalent?

Reset CMOS, system will not boot

This is a long story but I will try to keep it short:
I just bought a new 875P Neo-FISR and a 3.0 GHz Prescott, which from reading the other posts could have been a mistake. I installed the CPU, memory, and the video card and pressed the power button and received a "CMOS Data Wrong" error. So I tried to correct the problem but when I saved and exited then the system would not boot back up. So, I reset the CMOS via the jumper and tried again. After MANY attempts I change just the month in the date setting. And what do you know...it would not boot back up. The D-Bracket LEDs were: 1-flashing red/green, 2-flashing red/green, 3-red, and 4-red
I must have read almost every post in this forum and tried many things such as:
disconnecting all componets except for video, ram, and cpu
the during boot to recover the BIOS
removing mobo from case, maybe a short
moving the memory to different slots
moving the PSU to a different computer...it works
disconnecting the PSU from the mobo and and removing the battery overnight. The first night I did not disconnecting the PSU from the mobo and I found that did nothing.
Tryed everything that I could think of and some stuff that others thought of but nothing worked. However the last item...removing the battery...did change things some. Now nothing happens, and I mean nothing...no lights, no fans, no buzzing...nothing.
Any ideas would be greatly appreciated. The only recourse I have left is to RMA the board.

I tried one stick in all of the slots with and without the sound card. That did not work either.
The voltage for my memory is 2.6 so that is what I tried. But if I can get it to boot up again I will try 2.7.
Tks.

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!

The 420R first shipped in November 1999.
Initially, they all had CDROM drives and not DVD readers.
You might also get that same error
if you are inserting a DVD disk into a CD drive.
Next, the 390-0025 DVD drives had problems booting
from any DVD media with more than (I vaguely recall)
something such as 3GB of data on it.
They could read from them,
just not boot from them.
That was a peculiarity of the drive.
Recent releases of Solaris 10 fill those DVD disks.
Try your installation with CD media instead of DVD's.
