Machine no longer boots off cd

Just upgraded to 10.6.8 and can't boot off dvd anymore holding down "c". Is there something wrong with Superdrive, or iMac?
Thanks,

Nevermind,--I got a better disc and got it to work. I don't know what is wrong with the disc that won't work.

Lenovo T60p no longer boots

Greetings,
Well, now that I have repaired the fan problem, I am afraid I have created one.
My T60p originally had a drive with two partitions on it. A 90GB primary partition, and a 5GB secondary partition. Since I had to re-install the OS, the 5GB partition is no longer in use.
I tried to user Hirens utilities like Fdisk to see if I could use the space. I tried formating the space with an NTFS file system. That is all I did. Since then, the machine no longer boots.
However, using Hirens utilities, and instead of booting with the Hirens disk, I choose to boot from the hard drive, using NTFS. The machine booted fine so all my information is there.
How do I get it to boot without the Hirens disk now? It no longer gives me access to the programs that were on the disk....
Regards,
Jean-Pierre
P.S. I am trying to fix this myself, as with all issues on my laptop, before I take it to the Geek Squad. Thank you
for your input.
Here are the specs of the machine.

Hello,
It sounds like the primary partition may no longer be marked as "startable" or "active" in the partition table of data located at the end of the master boot record, which is what the MBR code uses to determine which partition's boot sector to load.
If you have a Windows XP installation disc, you can try booting from that, starting the Recovery Console (instead of an operating system installation) and using the FixMBR and FixBoot commands to repair the MBR and boot sector (for good measure), respectively.

Mac Mini (PPC) won't boot off install DVD

I'm having a major issue with my 1.24GHZ G4 Mac Mini. What I want to do is reformat the HD and reinstall OSX. But for some bizarre reason the machine refuses to boot off any OSX install DVD I throw at. I've tried Jaguar and Panther as well. If I hold down the C key during reboot and wait for the Apple logo to come up, I get that but it goes no farther. I can hear the drive being accessed (and I know it's not fault because it works fine under OSX) and yet I end up getting stuck at that logo screen. I can reboot the system normally into OSX Tiger.
I also strangely cannot partition the hard drive from within Disk Utility.
Can anyone give advice?

Possible options/questions...
a) Have you tried using the original Install DVD that came with it?
b) Have you tried booting into Single user mode and checked the drive? (Hold down Apple-S until it boots into text mode and when you finally get the prompt type 'fsck -fy' without the quotes).
c) Also, you may wish to try resetting the PRAM immediately before booting from CD. Let it reset THREE times (hold down Apple-Option-P-R or WinKey-Alt-P-R until it has chimed 4 times) and then hold down the C key to boot from your Install DVD.

MBP upgraded to Mavericks won't boot off of external drive

Now that I have upgraded my MBP to Mavericks I can not longer boot off of extrenal drives like I has in the past. I hold down the option key at boot up and it display the external drive as a bootable option but once clicked....it just hangs.
Has anyone else experienced this?
Thanks,

Well, want to rule out drive case,, as those do come up with EVERY new OS, just hit Lion 10.7 forum when it came out, or when 10.6.0 came out 3 yrs ago.
Maybe the power adapter is the weak link.
As I said, and goes back yrs, not a fan of FW/USB/eSATA case from major vendors (LaCie, WD, Seagate etc).
And you could try another case. Be sure to buy a case that lets you swap in your own hard drives though.

After installing Leopard, my G4 will no longer boot in OS 9.22. (Classic still works, but I need it to boot in OS 9.) Any clues about what the Leopard installer might have done to my machine that rendered OS 9 boot unusable? What can I do to fix it?

After installing Leopard, my G4 will no longer boot in OS 9.22.
(Classic still works, but I need it to boot in OS 9.)
Any clues about what the Leopard installer might have done to my machine that rendered OS 9 boot unusable? (And what can I do to fix it?)
Details:
G4 Gigabit Ethernet
Boot ROM version: 4.2.8fl
Accelerator card added: 1.6 MHz
1.5 Gig Ram
I have erased the partition that had Leopard installed on it.
I zapped the pram.
In Open Firmware, I "reset-nvram", and then "reset-all"
I tried to reinstall G4 FW Update 4.2.8, but that must be done when booted from OS 9, and of course, that's the problem: it won't boot into 9.
I tried restarting from 9.2.1 DVD.
I tried restarting from an external firewire drive containing OS 9.2.2.
I tried moving a fresh OS 9.2.2 system folder into an empty partition on an internal hard drive. (Partition was created WITH OS 9 drivers installed.)
All attempts to boot into OS 9 give me the same results - grey screen - no spinning beach ball, no icons or logos - just a blank grey screen.
This machine still works fine in OS 10.3 and 10.4, and it worked fine for many years booting into OS 9, until I installed Leopard, and I haven't been able to boot into OS 9 since then, although I have done considerable research online and tried many things.
I have since learned that this machine does not support Leopard - 10.5. Fine, but how did it break 9.2.2?
Any help greatly appreciated.

Thanks for checking in, BDAQua.
Problem solved.
In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
"If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.
Gratefully,

[SOLVED] After pacman update, system no longer boots

Updated pacman packages, and half-way through the upgrade proces fails (it mentions not being able to find package-control). Upon investigating, I notice no programs are working. I ls /usr/bin and it is empty! In a panic, I restart the machine, and it no longer boots up.
My boot is on sda3 and /root is sda5.
When bash starts up, it loads the kernel fine, and then after a second it panics and exclaims: "No init found. Try passing init=bootarg".
I load up my trusty Arch livecd and fsck the partitions. Fsck claims both partitions are clean. I am able to mount them and examine the file structure: all files look like they are there. I then try to chroot the mounted partition (sda5, my /root), and get the error that "/bin/bash" is not found, even though it is there in the correct directory. Not sure what to do now.
My grub entry, which has always worked fine prior to this:
legacy_kernel '/linux344-ck' 'acpi_osi=Linux' 'root=/dev/sda5' 'rootfstype=ext4' 'init=/sbin/init' 'pcie_aspm=force' 'acpi_backlight=vendor' 'i915.i915_enable_rc6=1' 'i915.i915_enable_fbc=1' 'i915.lvds_downclock=1' 'ipv6.disable=1' 'i915.semaphores=1' 'modprobe.blacklist=bluetooth,uvcvideo' 'ro'
legacy_initrd '/initramfs-linux-fallback.img' '/initramfs-linux-fallback.img'
UPDATE: solved issue. I didn't read the news. Upgrading via pacman broke my system because of this. Now I know! System is running smooth again.

Huh. I guess the problem was a couple of stale and crusty {,f}getty .service files, and an obsolete slim.service file I created a while back.
Removing them fixed my problem, although tty1 still shows boot messages (not a problem, and may not even be "new" behaviour)

Z77A-GD65 no longer boots with 4 RAM modules

I had 4 x 8GB Cosair Vengeance LP that used to work fine, but no longer boots into Windows with 4 but only with 2 RAM modules. Any help in solving the issue would be appreciated. ( I need 32 GB as I run many virtual machines )
The 4 modules worked fine for few months until couple weeks ago, when I saw issues with booting into Windows 7. The workaround was to "warm up" by leaving the PC in BIOS for about 5 minutes and it would boot fine. Since couple days ago, it would POST but not boot into Windows or into live Linux on USB, so I started troubleshooting with bare bones first ( MB, CPU, 1 RAM, PS ) and then starting adding more and more components until I found that 1 and 2 RAM modules worked in either black or blue rail but with 4 RAM modules, it will POST, but not boot at all into either USB based live system or into Windows 7.
Memtest with 2 separate sets of modules pass with flying colors. Mixing the sets work fine too, but add 2nd set (i.e. 4 modules) and it fails to boot. I am leaning more toward believing the issue is with the MB than with the RAM since mixing them doesn't throw any memory error.
Any suggestion on how to check if it's the RAM or MB ?

What voltage is the RAM running? A slight bump up in voltage might help.
As to voltage, I started with standard 1.5 and then incrementally upped it to 1.65v. At 1.6v and above, it does boot into Windows, but intermittently goes into BSOD... Works perfect with 1.5v with 2 RAM modules.
I'll save the money for next build instead of going for 32GB kit. ... guess I'll live with 16GB for now.
Thank you all for the advice.

A late 2007 Mac Pro (2,1) no longer boots into 64-bit Snow Leopard

In Snow Leopard 10.6.7, my late 2007 Mac Pro (2,1/3.0 GHz/Dual Quad-Core Intel Xeon) no longer seems to be booting into 64-bit mode. I've tried holding down the 6 and 4 keys during startup and even used a Terminal sudo command to force the machine to always boot into 64-bit mode. No matter what I try, an About This Mac>More Info>Software check only reports the following:
     64-bit Kernel and Extensions: No
Before I upgraded from Leopard 10.5 to Snow Leopard 10.6, I carefully researched this, and this Mac Pro model specifically was listed by Apple as being capable of 64-bit booting — meaning that it would utilize at least some extra memory. At the time, under OS 10.5 and early versions of 10.6, when I used this Terminal command...
     ioreg -l -p IODeviceTree | grep firmware-abi
...my Mac Pro 2,1 returned this response:
     "firmware-abi" = <"EFI64">
As a result of my tests and research, I upgraded the installed SDRAM from 4MB to the theoretical maximum Apple indicated this model could support (16MB) so that Adobe Photoshop 12 (CS 5) would fully utilize extra installed memory under Snow Leopard. While using the first versions of 10.6 Snow Leopard, the machine worked fine in 64-bit mode. Now, in the wake of the 10.6.6 or the 10.6.7 update (I didn't notice which), I find that this model no longer even reports itself as being 64-bit capable, though it once did.
Now, the aforementioned Terminal query returns this response:
      "firmware-abi" = <"EFI32">
Also, the Library>Preferences folder does even not contain a file called "com.apple.boot.plist," which some owners have reported editing to force 64-bit booting.
The thing is, I spent a fair amount of money upgrading this machine to the maximum amount of SDRAM supported. I purchased it because it was advertised as being 64-bit capable and I upgraded it because Apple originally reported it as being a 64-bit model. Now, I'm not sure if the extra memory I added is being fully utilized, though Photoshop does report seeing 15547MB of available memory.
Have any other owners of these second-generation Intel Mac Pro's encountered this? Does anyone know what's going on? Am I doing something wrong when checking for the 64-bit installation or architecture? Is Snow Leopard 10.6.7 mis-reporting the architecture for this model? Or did Apple silently withdraw 64-bit support for this machine in a recent OS update?

Hatter: Thanks for the feedback and links. Well, as described in one of the threads you linked to, the document below reinforces your assertion that only Mac Pro's 3,1 or later (early 2008) support 64-bit booting in Snow Leopard:
http://support.apple.com/kb/HT3770
However, if you asked me in court, I would swear on a stack of Bibles that sometime in the past, I read an Apple document indicating that the Mac Pro 2,1 supported 64-bit booting and I really thought I recalled booting this particular machine into 64-bit mode under early versions of Snow Leopard.
I guess I'm mistaken. Certainly, this issue can be confusing. When I read them out loud to myself, even perfectly-written, accurate explanations on the subject can sound like a circular, non-sensical George Bush rationalization being delivered by comic Will Ferrell. I must not be correctly recalling the details of booting into 64-bit mode with this machine. And I guess that since Photoshop has its own memory management scheme, and I only have 16 gigabytes of SDRAM installed anyway, it doesn't matter that much. Furthermore, in one of your links, Jason Snell of Macworld writes:
"...If you’re running a Mac powered by an Intel Core 2 Duo processor or an Intel Xeon processor, your Mac is 64-bit capable. And Snow Leopard runs 64-bit-capable applications in 64-bit mode regardless of whether it’s booting into a 64-bit or 32-bit kernel. In fact, the only big advantage of booting into a 64-bit kernel would be the ability to use more than 32 gigabytes of RAM..."

Can no longer boot into Mavericks 10.9.5

My problem is that I can no longer boot into Mavericks 10.9.5 on my mid-2012 Macbook Pro. The problem arose suddenly without any known major changes to my software or hardware. The booting process freezes with the apple visible and the circle below it spinning endlessly. Every several seconds, the display very briefly gets brighter, then the circle starts spinning again and the process repeats itself. It never gets to the user login screen.
Other than keeping various apps up to date, I don't recall any recent major operating system or other major software updates, nor have I made any recent hardware changes. I've searched a multitude of threads and and tried any number of fixes without success. Here's what I've tried so far (and probably a few more that I can't remember): (1) Repaired the startup disk with both Recovery HD -> Disk Utility and single-user mode -> /sbin/fsck -fy; (2) Repaired the startup disk permissions with Recovery HD -> Disk Utility; (3) Reloaded the Mavericks 10.9.5 operating system twice; (4) deleted /Library/Preferences/com.apple.loginwindow.plist; (5) reset PRAM and NVRAM; (6) booted with "D" pressed and ran the Apple hardware test, which ran for about 40 minutes and reported no problems; (7) tried booting from a bootable clone of Mavericks 10.9.5 on an external hard drive, which also failed at the same place with the apple showing and the circle below it spinning endlessly. ***Oddly, I am able to boot from a bootable clone of Mountain Lion on an external hard drive. It's Mavericks that won't boot.***
Here is the part of the system log the repeats itself over and over and seems to correlate with the repeated failed attempts to complete the booting process. Any help would be appreciated beyond words:

Hi
You got a prob I think, if you can boot a windows, MSconfig, startup options might restore the boot files.Only other thing is to try and either load a new windows and let it setup a boot file, or perhaps a win98 startup disk, and fdisk, then set active partiton, which will set an MBR. But that would leave a load of work to do, I think I'd opt for an install of XP, and let it repair existing installation, and make a new boot file.
Hope you don't need the info on disks. If you do, I would install another HDD, load XP, then copy original Disk to save place.
Good luck

After Boot Camp partition, iMac no longer boots

Hi, I have a 20" iMac Core Duo (the first Intel Mac off the line) running Snow Leopard 10.6.4. I ran the Boot Camp Assistant to partition my hard drive, and it successfully created the "BOOTCAMP" drive. When it asked for my installation CD, I tried loading a Windows installation partition through a USB hard drive, but the assistant would not recognize it as an install disk. So, I closed out of the assistant early, leaving the Boot Camp partition in place. Eventually, I rebooted my machine in an attempt to boot directly from the USB drive and resume installation.
However, I found the machine will not boot at all. It powers on normally, makes the startup sound, but after a few seconds I'm left with just a flashing folder and question mark icon. Holding down Option-key at startup does nothing. Trying to boot from my Snow Leopard disc by holding down C or D during startup does nothing. Holding down Command-S does nothing. Holding down Shift-key does nothing. Resetting the PRAM does nothing.
What can I do? Is there some way I can access the on-board EFI to make sure the correct startup disk is selected? Why am I unable to boot from my CD drive?
Thanks for your help, everyone.

On OSX go to System Preferences the Startup Volume and reset your Windows 7 partition to be the default.
On the next reboot it should automatically boot into Windows.
A PRAM-reset http://support.apple.com/kb/HT1895 can be the cause of this behavior.

Windows Machines No Longer connecting to Shares

Has anyone experienced issues with their Windows machines no longer connecting to Shares on the server. I have a Windows 7 machine and a Windows XP machine that were connecting to the Shares without any issue. Then this morning they just stopped connecting. I can ping the server both through its name and through its IP address from those computers but when trying to map a network drive all I am told they cannot find the server to connect. I have set all the appropriate security settings on both machines as suggested in numerous articles. SMB is turned on for the server.
I have made no changes to the server in the last 24 hours other than to turn off file-sharing and turn it back on to address an issue with Time Machine backups not occuring due to image being locked in use.

i have a vaguely similar issue, where my server is a member of the domain(workgroup on mac) - suddenly no users from the domain show in users panel,
and connections are not accepted... 10.8.3/server 2.2.1

My trusty Mac LC no longer boots from the HD

I purchased a new Mac LC many years ago and it has served me well until recently when it would no longer boot from the hard drive. When I boot from a Disk Tools floppy, I get some limited success but do not ever hear the HD spin up. The startup chime also does not sound. When used as the boot disk and trying to use the installer option, the program can't find a SCSI drive, only the floppy drive. The 5V & 12V to the HD are right on and a new PRAM battery is installed. I can load and run programs using the floppy drive but that requires a lot of disk swapping. I tried substuting a tested Apple LC HD with the same results and now I suspect the problem is not the HD but is somewhere else. Any help would be gratefully appreciated. Thanks!

Thanks to Jan & Jeff for their quick response to my question. Here is some additional background information which may give you both some more ideas.
The original 40 MB HD was replaced with a 120 MB HD along with an increase in RAM to 4 MB sometime in the first year after I bought the LC. The 40 MB HD was installed in an APS (?) external SCSI box with its own power supply. OS 7 was just becoming available and Apple gave me a set of disks even though OS 6.x was in the computer so I put OS 7 on the external (40 MB) HD. Everything worked great for 20 years although there were periods of intermittent use when I used other computers for work, Internet, and e-mail. I powered up the external HD infrequently but it worked fine the last time I tried it some months back.
Then when I fired the LC up 6 or 7 weeks ago, it would not boot unless I turned the power switch on & off 2 or 3 times in succession then everything functioned normally. Then it would not boot at all even from the external HD.
Now, to address some of your comments and observations:
All connectors, plugs, SIMMs, and socketed RAM devices were removed, examined and replaced. All electrolytic caps showed no signs of leakage or swelling and the PWB looked in its original condition.
The +5, -5 and +12 voltages measured at the power supply connector were within 1%. When I originally thought I had a HD problem, I opened up the 120 MB HD and when trying to boot, the platter would give a slight twitch with no tendency to spin. A friend of a friend (a MAC serviceman) brought a couple of vintage drives SCSI over to try with similar results. The Apple HD I purchased was tested and guaranteed, although wiped clean. It has since been returned. As I said in my original question, the Installer on the floppy could not find a SCSI drive. In all of my efforts I could never get any of the hard drives to spin up.
Although I have a MacMini (OS 10.6.8), I still used the LC because for drawing schematics and floor plans, printing labels, etc., simple is better for me. Is there any hope that I can get my LC working again?
Many thanks for your help and suggestions. len-35

Resizing Windows Partition - No Longer Booting

Whenever I attempt to setup a Windows/Linux Dual boot I get hit with this same dilemma. I start off with a NTFS format partition with Windows XP on it. As soon as I resize the partition, it no longer boots. Even before installing linux/grub. I defragmented before attempting this, and I took every precaution. In the end, I'm never able to boot my Windows OS. I can boot Linux from the Grub menu, and I can still access my Windows files.
As of now I've reformatted back to Windows. I would just like to know what went wrong because I want to attempt another install later on.

Ward,
windows is weird in that it notes somewhere the block numbers where the system is installed, and when that moves
it does not boot anymore.
Now you are making life more complicated then necessary: if you still have windows resized and installed (and not booting),
you can use the windows install cd and go into repair mode. It will fix the resized windows.
If you are starting from scratch, before installing windows, start a Linux live CD, do not install it, start the program
"gparted" and partition your disk as you want it. Then install windows in one of the partitions.
Instead of the Linux live CD you can also use a Gparted stand alone CD:

Hope it helps.

IMac will no longer boot ANY version of Windows CD/DVD

I have a 20" unibody iMac 8,1 that originally came with Leopard and has been upgraded to Snow Leopard (currently 10.6.1). During Leopard days, it had Boot Camp running Windows XP (for games) and worked fine. At some point, boot camp was removed and the system was returned to a single partition. Recently, I've decided to install Windows 7 Ultimate 32-bit (retail cd) and so went through the Boot Camp Assistant to create a new boot camp partition and launch the Windows installer DVD. After going through the partition process successfully, the Windows 7 DVD failed to boot, ending in a black screen with a flashing underscore ( _ ). I tried to boot the Windows 7 DVD several times with the same result. Thinking that somehow the Windows 7 DVD was damaged, I got out my Windows XP install CD and tried to boot that, with the same result (black screen blinking underscore _ ). I tried this with a retail copy of Vista Ultimate 32 bit, with the same result. I have run Disk Utility and verified the disk contains no errors. I have tried manually forcing the boot to the Windows install DVD/CD's by holding Alt during boot, and manually clicking on them, with the same result. I have backed up the entire HD with Super Duper and erased the disk and then restored the from Super Duper copy, in case there was a problem with the partition table. All with same result, blinking underscore on a black screen when attempting to boot off Windows install media.
This machine used to have boot camp successfully running XP under Leopard. Now I can't even boot from a Windows install CD/DVD (any kind of windows). What has happened? Did the Snow Leopard installation change something? Is there a firmware update that is needed? I have tried resetting PRAM and SMC with no result. I am out of ideas. All of these windows install disks work fine if I boot them with my MacBook Pro. It's just the iMac that won't boot a Windows install DVD/CD, of any kind.
Help!

I can boot both Snow Leopard and Leopard install disks, no problem. I cannot boot ANY version of Windows install disk (XP, Vista, 7). My Super Duper backup was a backup of my Snow Leopard install to reformat the drive, since one theory was that the partition table was messed up. No go.

X200 auto-update BIOS upgrade failed? system no longer boots

Hi,
I've had an X200 for around 7 months now and just did an auto-update earlier today. One of the items was a BIOS update, so I thought what the heck, it should be fine, always has been before. The update completed correctly and shuw down for reboot as planned.
The system now no longer boots. Nothing at all happens. When I press the power button, no matter whether with AC supply or on battery, the following happens:
- num lock, caps lock, HDD and 'power on' lights light up for a second or so then go off again
- they come back on again for another second, and off again
- then only the bluetooth light and the 'power on' light remain lit, and nothing else happens
It seems pretty fried to me. What can I do? I'm in severe despair! :'(
Thanks in advance for your help,
Phil

Hans;
Thank you for the reply. Say hiya to Amelia for me. Does this mean you're an alien?
Ok, I tried using bootable CD and no go.
I don't really have a simpler graphics card around to try that. So that test may not happen.
I can try with one dimm when I get home (I'm at work atm.)
I also thought about putting the drive into another system and will try that also later today or tomorrow morning.
D-Bracket: I will have to watch that again. It really didn't make sense to me as the lights went through a lot of the steps then came to a halt at what I think was BIOS Sign on. Someone did suggest to me that I might have a virus, which may be why the second hard drive failed eventually. But I'm not sure about that and not sure what can be done about that unless clearing CMOS would take care of it.
So, any new thoughts?
