The system not booting

I am receiving a message telling me to restart the computer using the power off button and then powering back on. This is not working. Any other ideas?

Is this a message in multiple languages? If it is then you are experiencing a kernel panic. Visit The XLab FAQs and read the FAQ on diagnosing kernel panics. If you can post a panic log entry that would enable us to see if we can help: Mac OS X- How to log a kernel panic

Pacman -Syu update, System not booting due to systemd

I have just done a full update on pacman, and now my system is not booting due to this message
systemd[1]: /usr/lib/systemd/system-generators/systemd-gpt-auto-generator exited with status 127
Does anyone know what is causing this, and what a status code of 127 means?

fstab originally existed on my OS before the pacman upgrade. After the upgrade I got the error message mentioned above (and obviously the fstab was there since I didn't touch it). Then after reading that linked topic (where a similar error message was the cause of systems not booting due to a fstab), I deleted the fstab (or more accurately, moved it somewhere else)

System Not Booting Up

I have an iMac Flat screen running Mac OS X 10.3.9(Panther). At times, when I turn my iMac on, I do not receive the start up screen with the Apple logo and progress indicator. I receive just a blank white screen with no indication that the computer is loading. I do not hear the hard Drive clicking. The boot up sequence never proceeds to the second second screen with the progress bar or the desktop with the Dock. The computer does not respond to pushing the on/off button to turn the computer off. I have to power cycle my power strip to turn the power off. I have verified the Panther10.3.9 icon is in the far left of the System. Preferences-Start-up Disk.
Recommendations would greatly be appreciated.

Hi Ali, Cornelius, and littleshoulders,
I checked my CD;s that came with the system when I purchased it and found no system disks. When I came home from my vacation this past weekend and turned on the computer, I received question mark during the start up. I had my cousin, who wrote earlier, come over to look at the computer. He brought a DiskWarrior 3.02 and an Apple Protection Plan CD that contained Tech Tool Deluxe. When inserting the Disk Warrior and pressing the C Key, the system wouldnot boot up. We would get the Apple logo and the progress circle but then the screen would turn blank and a loud fan type noise would come on the iMac. We powered it down. we next placed the Tech Tool CD and pressed the key start up and the Tech Tool diagnostic window came up. We ran the diagnostic and everthing passed.
Still thinking that something may be wrong with the computer, we again tried Disk Warrior. We ran the disk Warrior from the desktop. We were unable to rebuild the system directory. The rebuild button was not active. Testing the hardware showed the drive normal and functioning properly.
My cousin had a copy of the Tiger install disk and when it ran showed no disk utility. His Panther install CD would not mount when pressing the C key at startup, so that was no help.
I am desperate now, not knowing what to do. Since there is no apparent things wrong with the hard drive should I just invest in a copy of Leopard or what?

Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up.

Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up normally. Why do these key fonctions no longer work?

It could be your timing if on a bluetooth keyboard. I find it best to hit the keys as soon as i hear the chime, release and hit them again but this time holding them before the chime ends....like a fake pump in football.
But....you can always open up system preferences, startup disk, and select your bootable clone for booting. If it doesn't show up there, the Mac doesn't think it's bootable.

How come the sight was down so long? and why does the system not send emails anymore with responses?

The system is back up and fully functional. How long has it been since you stopped receiving notifications? Can you share your form with us so we can have a look into what might be going wrong?

Windows server 2008 r2 operating system not booting in normal mode after unstalled the virus gaurd

Windows server 2008 r2 operating system is not booting in normal mode after i uninstalled the virus guard in the system. I tried to repair the system but repairing option not available in server 2008. i can log in to the system only safe mode.
Please help me to solve this issue as soon as possible .I do not have the any system backup with me .

Hi,
Regarding the issue here, please restart the computer and press F8 until you see the
advanced boot options, select start windows normally,
if it starts with no problem, please check if you have the option boot from safe mode checked:
run->type msconfig->tab boot->boot options, check if the
safe boot is selected, if yes please uncheck it. Then restart the computer to check if this problem still exists.
If the system needs repair, please take a look into the below WIKI article, and check the event viewer to see if any errors for further troubleshooting.:

How can I obtain a complete Time Machine backup (about 300 GB), with Windows 7-Parallels Desktop, without the system re-booting automatically?

I have been operating my MacBook Pro 15" (Mac OS 10.7.5), with Windows 7 - Parallels Desktop, for about one and one-half years. However, whenever I execute a Time Machine back-up, and leave the system to complete the process, I return only to find that my system has re-booted, long before the back-up is completed. I do not use the auto-backup feature because I do not see how to change the shedule for backups away from the default schedule of hourly backups (too my stain on performance). Is there something that I am missing in setting up for such a back-up? I am currently operating away from home, using wi-fi for Internet access.
Appreciatively, Arbyem

Understanding the system log (boot time 2 minutes)

Dear Apple Discussion,
I am trying to read the system.log correctly - mainly because my boot time is 2 minutes.
I have read that the beginning of the boot up is indicated by the line:
localhost kernel[0]: standard timeslicing quantum is 10000 us
is this correct?
Next, does the line:
loginwindow[165]: Login Window Started Security Agent
indicate that the login window has come up?
If both of these are correct then my boot time should be 18s (according to the time stamps in the log) - it defefinitely is not that.
Does the boot process start instead at this line:
shutdown: reboot by root:
If this were the case, the boot time would be closer to 2 minutes according to the log (which is what it actually is).
This then brings up the next problem: the two minutes basically come from the following line:
Nov 29 17:30:24 Purrfekt shutdown: reboot by root:
Nov 29 17:30:24 Purrfekt SystemStarter[177]: authentication service (194) did not complete successfully
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : unloading cisco ipsec kernel module.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : detaching from interface: en1.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : interface en1, filter has been safely detached.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : detaching from interface: en0.
Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : interface en0, filter has been safely detached.
Nov 29 17:32:12 localhost kernel[0]: standard timeslicing quantum is 10000 us
ending line of the boot process occurs at (if my above assumption is correct):
Nov 29 17:32:31 Purrfekt loginwindow[165]: Login Window Started Security Agent
So why does it hang for so long at this one process? Am I reading the log incorrectly? I have searched around here and also on google ("slow boot time", "cisco vpn tiger", etc..) but haven't found anything relating to my problem.
Thanks for any help.

v.1 PowerBook G4 15'' Mac OS X (10.4.3)

I am trying to read the system.log correctly - mainly because my boot time is 2 minutes.
It appears to be that a restart or shutdown process delays nearly 2 minutes rather than a startup process, presumably due to one of WindowServer children or a bug stays in Mac OS X 10.4.3 Update-- Mine delays approximately 30 - 40 minutes on PowerMac G5 2.7 Ghz on every shutdown or restart process. Your computer is PowerMac G4 so that make sense. I found a suspect application which is a security related. Although I am still investigating further because the issue does not occur on the lower drive bay where I install another Mac OS X 10.4.3 Update (but no third-party software) as a test facility.
localhost kernel[0]: standard timeslicing quantum is 10000 us
This is correct and the first line to display sequential events in a boot process.
loginwindow[165]: Login Window Started Security Agent
This is also a normal behavior.
SystemStarter[xxx]: authentication service (xxx) did not complete successfully
This can be displayed depending on a computer configuration.
A sequential event from CiscoVPN: unloading cisco ipsec kernel module to CiscoVPN: interface en0, filter has been safely detached seems to be all right if you PROPERLY configure VPN policy and IPsec (Internet Protocol Security) authenticate, etc for your Cisco device. IPsec is a framework for a set of protocols for security at the network or packet processing layer of network communication.
I suggest to check all related settings with Netwrok/Sharing panes and the router configurations for VPN (IPsec), IPv6, security, etc. Also check routing table and all socket connections after you launch Network Utility or via Terminal commands.
FYI: interface en0 is a wired connection and interface en1 is a wireless connection such as AirPort. IPsec kernel module is a unit of kernel program or componet for IPsec.
Hope this helps.

Did you do vgscan first? What error did you get or did the command just return empty?
Is the lvm2 hook in mkinitcpio.conf? Have you tried regenerating your initramfs?

System not booting after installing 2010-006 on MacBook Pro.

Today I've installed security update 2010-006 onto a current model, 13" MacBook Pro (the 2.4GHz one if that's relevant) and now it won't boot, just the spinning circle.
If I put it into verbose mode then I get "no suitable image found" and then "the system bootstrapper has crashed: trace/bpt trap".
If I try and boot from the Snow Leopard install DVD then it comes up with "you need to restart your computer" and I can't get any further (this is a working DVD as I've tried it in another machine, and I've also tried booting the installer from USB with the same error).
Is there anything I can do? The hard drive seems fine, and I can reinstall it if I must, but naturally want my data back, as though I have a backup, it's a few weeks old now.

Having a similar issue here on an Intel Core Duo iMac. Updated last night and system wouldn't boot. Some of the "offending" lines in verbose mode:

Booting from my Snow Leopard DVD caused a different kernel panic.
Booting in Safe mode (holding down shift) is possible (wouldn't be posting this otherwise lol), but I don't know how to update the offending kernel extension. Software Update updated correctly and there are no other pending updates.

XP system not booting since installing ITunes

I successfully installed a 2.0 USB card onto my XP box, however the installation of the iPOD drivers and Ituns gernated errors, and sicne then, my PC will not boot in normal mode, even with last known configuration (The iPOD itself, though connected during the entire boot, gives a normal usage display rahter then "do not disconnect" throughout the driver laoding phase, which never finises. It is however, possible to boot the device, and access the USB and iPOD in SafeMode. What should I do?

No dice. The computer is about 3 years old, with USB 1.1 and sound native to the board (Intel board). I installed a 2.0 usb PCI card without incident, but after installing the Ipod software, a conflict seems to have arisen. Boots fine in Safe Mode with Networking. Leading me to think there is some sound driver conflict.

System not booting keep rolling for hours

I need help, my iMac mal-functioning. @ boot it will not boot to desktop, some 1 should pls help

Hello,
What happens or shows if you hold the Option or alt key at bootup?
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Keep us pposted as to any progress or failures.
