Computer will not boot up correctly in any mode.

Hello,
I have a Compaq Presario CQ62 with Windows 7 that will not boot up to my log in screen and it does not matter what mode I put it in..safe..etc. I have tried everything I know to do ...like system recovery in the recovery manager. I have no recovery disk or anything. Any help

That means the internal drive has failed, or there's some other hardware fault. What backups do you have?

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.

Yeah it's dead. Take it to an Apple Genius Bar and have it checked out. Then buy a new one.

Powerbook G4 will not boot normally, only in safe mode.

So...about a month ago I updated my powerbook with all the updates that were available, one of the updates was 10.5.8. I came back after the update had run for a while, and found my computer with a black screen, and a faint white bar towards the bottom of the screen. The computer wouldn't respond, and I was forced to do a manual shutdown. The computer would then not boot, instead finally resting on a light blue screen with an active mouse pointer after passing the gray apple screen.
In safe mode, I downloaded and installed the combo 10.5.8 update, but it made no difference.
I assumed it to obviously be a software issue, and so I backed up my info, and reinstalled Leopard. I then updated to 10.5.8 using the combo update. My computer functioned normally for about a week, and then froze, mouse responsive, but nothing else. After manual shutdown, same problem, computer started to blue screen with pointer.
Since that time I've reset the PRAM, run disk utility a million times (no errors), repaired permissions, all to no avail. I've run the Techtool diagnostics on it, and it found no hardware failures. The computer will not boot from an external hard drive, ruling out the HD.
I've replaced the RAM with different RAM, again will not boot. The computer boots without fail every time in safe mode.
History on my computer, one of my memory slots failed to recognize memory any longer, and my logic board was replaced a little less than 2 years ago while I still had applecare.
So to sum up:
Powerbook boots only in safe mode
Stays at blue screen with mouse pointer when booting
May work properly for a few days after erase and install of OS, but then fails again with same systems shortly thereafter
Any ideas???

Have you tried running the Apple Hardware Test from DVD?

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102.

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102 and it keeps circling through the same error. Also the screen is so faint (pressing the F1 and F2 keys don't do anything). I got this from a friend and he didn't have any of the original discs. Any suggestions? From what I've read it's a problem with a recent update. I've never had a Mac so I'm trying to learn and fix it.

I just had an issue like this. I was able to boot up with an external firewire drive, although it was a lot of trouble. I think doing an option boot finally worked; holding down the option key, I eventually got to see the firewire drive was bootable, and booted from it.
I put the thing in verbose boot mode (command - v , I think; but please look it up. I have no Mac books at work to check). In verbose mode, you could see that the hard drive could not mount; the OS tried to do fsck, but it failed around 2/3 of the way, and the CPU was halted.
I was occasionally able to boot normally, but never in safe or single user modes; these do a disk test first, which invariably failed.
I could see from the system and console logs when I managed to get the firewire boot going that there were repeated errors trying to access drive s03, the internal SATA drive. The logs on the SATA drive showed huges numbers of errors. At a wild guess, for some reason a lot of sectors went bad all at once. There had been a some erratic behavior before, but I'd put that down to the single processor G5 problems. (these were non video related, just freezes).
Applecare wanted me to carry the huge thing into the local Apple store, but I persuaded them to just send me a replacment hard drive, which they did. The new one works perfectly.

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.

Mac Pro will not boot from Leopard or any CD or DVD install disk

My Mac Pro wont boot from my Leopard install DVD. It never gets by the gray screen, then after several minutes the screen scrolls down black and says I need to restart my computer. I tried my Tiger install disk and it still wont boot from that DVD. Held down the "C", used "option" and selected DVD and still no boot. I can boot from one HD that has Leopard 10.5.8, but another HD with Snow Leopard 10.6.3 will not boot. The HD with Snow Leopard shows up as "EFI Boot" not the name I gave that HD when I startup using the "option" key. Any help would be appreciated.

At first I was just going to say it sounds like you have a bad optical drive, but then you had to go and say that it also won't boot from a HDD.
That just makes things a whole lot worse.
Start by removing the side cover and checking the RAM to see if any of the LEDs are lit up indicating bad RAM. Usually if there's any bad RAM found, it will just automatically disable that stick, but maybe yours isn't for some reason.
Look for any other LEDs that may be lit. Generally speaking, the only time you should see an LED (outside of the power LED) lit consistently is if there's a problem.
You should also see if you can get Apple Hardware Test to run, which may or may not find some problem.
But sorry to say, it's sounding very suspiciously like a bad logic board.
One other thing to try, is putting the SL drive into a different slot. So if you were putting it in slot 2, try slot 3 or 4. If you just have a bad SATA port, you might be able to just work around that until you get a new system.
If by chance this system is still under warranty, do not walk, do not pass go, do not collect $200, RUN to the nearest AASP or Apple store to make it THEIR problem to sort out.

My macbook pro froze last night and I held the power button down to restart the computer. Now the computer will not even start up. Any ideas what may have happened?

While searching the internet last night my Macbook pro froze up and would not respond to anything. I restarted the computer and now the computer will not ecen start up.

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.

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.
