Welcome to Macs and the Forums.
Don't panic. All will be well.
It may be that you lost some of the startup/login essentials, but could you give forum helpers here some indication of what you did so that someone could best advise.

    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitiion & use Disk Utility from there to Repair the Disk, then Permissions.
    Re-install if that doesn't work.

  • Help needed on startup. My computer will not boot from the CD drive!!!

    Problem with iMac G3 333, the Message on the screen states: "The System Software on the starup disk only functions on the media, not if copied to another drive." Like a fool, I copied the system folder from the original system software 9.2.2 on to the iMac. System disk which is not a complete system folder when used on the computer. I have searched the Internet, but can not find an answer. I have tried everything, holding down the C key, "Delete, Opition, Apple key, shift" holding the mouse down on startup, various combinations of other keys, etc. The CD starts to spin, but the computer switches to the hard drive and the message above returns. No matter what I try I still can't boot from the tray loading CD drive. Is there any Firmware code that I can use. I know how to access Firmware on the Imac and can boot the iMac using Firmware, but I don't know how to use Firmware to boot the CD drive which I need to do so I can reload the original software. CAN SOMEONE PLEASE HELP? Thanks, Jim

    Yes, I have tried both System Softwares a number of times. The C key will not boot up the CD drive and the harddrive always boots with the original message. I need to get the CD drive to boot so I can reloaded tge original software. Do you know anything about booting the CD drive using Firmware? Jim

  • Computer will not boot up.  I have tried running disk utility and re-installing OSX.  It says disk locked

    I am new to Macs and have bought a 13" Macbook Pro and a IMac 21.5" 14 months ago.  I have only used the Macbook pro about 15-20 times and after upgrading to Maverick it will not boot up.  I get the white screen and a spinning circle.  I have tried Disk utility repair and even re-installing the OSX, but it says disk locked.  I do not recall setting any password protections or passwords.  I now have a brick with a lit up Apple logo.  If anyone knows how I can bypass the disk lock error or reset the laptop, please let me know.  This has not been a pleasant conversion from PC's.  Even my IMac blacks out from time to time and both happened right after my factory warranty expired.

    The internal drive is malfunctioning. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

  • Blue screen, computer will not boot up

    My computer, when powered up gets stuck on a blue screen and will not boot up. I have restarted & held down the shift button for safe mode & it goes to a white screen with a grey apple icon but will not move past this screen. How do I get the computer to boot up?

    Sounds like your system is hosed. Try [repairing the hard drive with Disk Utility|http://support.apple.com/kb/TS1417]. Of course, from the sounds of it, even if you get the drive repaired, it may not fix the problems with your system.
    Do you have backups? If not, your only priority at the moment should be to figure out how to back up your data, or what data may still be intact if your drive is badly damaged. If you have another Mac, the easiest way to do this will be to boot the machine into [FireWire target mode|http://support.apple.com/kb/HT1661] and copy whatever data you can.

  • Computer will not boot up but fan will turn on and stay on.

    I have a Gateway and I did not have enough memory.  I bought 1Gig to give it enough memory to run the basic systems.  I added the memory to the slot in the hard drive and now it will not boot up.  The fan just turns on and runs.  I took out the new memory and it does the same thing.  No working computer.  Need help on what I should do besides Punt.
    Thanks,
    ZCDJSouza

    First and foremost, recheck all internal connections to make sure you didn't bump something loose while replacing the RAM. I had the exact same thing happen to me once before only to find that I had accidentally loosened the cable to the hard drive.

    COMPUTER DOES NOT BOOT UP ERROR MESSAGE HARD DISK 1

    Sounds like the hard drive has failed and will need to be replaced. If you are still in warranty HP will send a replacement. If not a retail laptop SATA hard drive can be used. Just be sure to get one of at least equal capacity as the original in order to use Recovery Discs. It can be larger, but not smaller capacity.For instance  you have a 640GB hdd so you could use a 750GB hdd but not a 500GB hdd.

  • Computer will not boot up after recent software install

    I recently tried to install a series of software updates. Not all were successful. Soon therafter the computer froze up while in safari. I turned it off and the computer would not boot up on restart, and instead sent me to the darwin login screen. I rebooted in safe mode per these forums, and turned off an itunes startup function, and then rebooted. That seemed to do the trick as I could now get back into the OS, but the computer was dreadfully slow. It froze up again in Safari and I turned it off again, and this time it would not go past the grey startup screen with the apple. I tried safe mode again, but the computer would shut down around 30 seconds after the wheel below the grey apple started turning. I Was able to get my Tiger Install DVD in the drive, and turned the computer back on, but now just get the grey apple screen and the wheel spinning indefinitely. I cannot do an erase and install because my photos are not backed up. Please help!
    Thanks

    Hi, Deaton41. Welcome to the Discussions.
    You wrote: "I recently tried to install a series of software updates. Not all were successful."I suspect the only way you are going to resolve this is by performing an Archive and Install. For important tips on this process, see my "General advice on performing an Archive and Install" FAQ. Perform the steps therein in the specified order. If you follow my FAQ's steps to the letter, then your photos should be AOK, assuming directory corruption hasn't damaged them. I suspect directory corruption is the root cause of the unsuccessful software updates, which that then led to your current problem re: start up.
    Before installing future software updates, you may wish to consider the advice in my "Installing Software Updates" FAQ. Taking the steps therein before installing an update often helps avert problems and gives you a fallback position in case trouble arises.
    Good luck!

  • Bios recovery - Computer will not boot up

    I have a HP Pavilion HPE H8-1145-SC, my bios will not boot.
    I was wondering if there are any ways of changing the jumper setting on the motherboard ( IPISB-CH2) to fix this issue if so how do I do it? or are there any other types of recoveries that I can do.
    I have searched the forum for answers and tried some such as taking the battery out and putting it back in but it hasn't worked.

    You could not get a boot menu when using a boot disk, any messages on the black screen at the bottom?   Could you do me a fav and take a pic of that black screen and post it. I think... not sure yet but this can be your memory. 
    I would ask for you to preform a memory test using memtest86 but if one disk does not boot this may not either. But still worth a try.  If you burn a memtest86 disk and reboot see if it boots into the memory,  if not the issue is memory most likely.  Do you know how many GB of ram you have installed?
    Do you feel like you can opening your case and removing memory dimms? If you have a bad one this may stop it from booting. I hope the memtest86 works cause it would detect that.  Windows 7 can boot on 2 GB. If you have  say 6Gb than each dimm would be 2GB taking out one at a time keeping one in and see if it boots.
    http://www.memtest.org/#downiso
    In the window about the first list download the zip Iso and burn it to a CD
    ** Memtest86+ V5.01 (27/09/2013)**
    pre-compiled bootable binary (.zip)
    If you feel that this would not work I suggest taking your system to a PC repair shop and have them test the memory.

  • HT1758 Power failure in the middle of a software update and not the computer will not boot up.  The computer just has a white screen with a grey apple and just loads non stop.

    My iMac will not boot up after a software update.  the screen is all whute will show a grey apple in the middle and will look like it is working but nothing happens; this can go on forever.
    Does anyone have any suggestions?

    Do you have a backup in the form of a bootable clone or Time Machine? Restore that and then try the update again.

    Another option might be to download the standalone from Apple Downloads on another Mac and try installing it in Firewire Target Disk Mode to the Mac that was interrupted during the update.
