Imac G4 install boot issue: Blank screen

Hi!
I'm trying t get archppc on an old g4 with 512 ram (the infamous iLamp). I get the cd to boot part way, but then I get a blank screen, and the computer doesn't move forward. I tried using the option that does something to the video (sorry, I forgot what it was called. I'll try getting it in a few minutes), but it did the same thing. I'm using xubuntu right now, but it's like puling a trailer with a coupe. I want just what I need: openbox, internet, terminal. So anything else is quite useless.
Thanks a lot!

Hi! I may come too late!
I installed Arch ppc on a Mac mini G4 a few months ago.
After udev was parsing the hooks, had a ' black screen flash' then 'nothing' (reading my notes, I can't remember if it was a white screen, but I had that one when trying to install other systems like Debian or Crux on ppc machines when it was about communicating with GPU).
On Arch ppc, the way through the problem was to reboot from the install cd, chrooting again, and edit yaboot.conf adding these two lines after the proper boot image :
append="video=radeonfb"
append="radeon.agpmode=-1"
Your GPU is most probably an ATI and should be ok with that, but check anyway.
And don't forget to
ybin -v
again before rebooting!
Hope this helps someone, if not the OP.

Intel iMac will not boot past gray screen

Intel iMac will not boot past gray screen
my system:
new (month old) 24" intel imac, 2.8 ghz, 4 gb ram.
running: leopard (upgraded from tiger, which was pre-installed at purchase), installed 10.5.1 update right before this huge problem occurred.
install discs on-hand: two-disc tiget set, single leopard upgrade disc.
what led to this:
i wanted to install windows using bootcamp on a 50 gb partition.
at this point i was running leopard 10.5
i followed all bootcamp instructions, printing out the guide, as well. once i got into the windows setup, i was prompted to choose a partition to install windows. unlike the bootcamp guide, which showed three partitions, one clearly labeled "bootcamp", i saw only one partition. not wanting to risk writing over my mac partition, i quit the setup and rebooted the mac os. after some googling around, i looked for firmware updates (didn't need any), and then software updates. i decided to try updating to 10.5.1.
i then ran through boot camp again, deleting my previous windows partition, creating a new one, and moving forward as before. once again, i was only shown one partition to choose from in the windows setup. i exited the setup again to reboot through the mac os, but this time, i was only given a blank gray screen.
here's what i have tried so far:
booting from a CD, holding down the C or D keys: no response (in fact, i have to restart the computer holding down the mouse button to be able to eject the CD)
booting with option key held down: gray screen
booting with option key held down with external bootable firewire drive attached: the firewire drive appears as a boot icon, and i can click on it within a five second window, but then the screen freezes after that time period, and nothing changes
booting into target mode while attached to another mac: gray screen (no firewire icon, and drive never shows up on other mac)
resetting NVRAM: i'm able to hear the boot chimes, but no difference in performance. gray screen every time
Safe boot: nothing but a gray screen
Verbose mode: gray screen
Single user mode: gray screen
Single user mode with firewire drive attached: occasionally (not every time), i am able to get the white on black terminal to show up. from here, i'm able to run fsck, but it appears to only be checking the firewire drive. i have tried several times to boot from here, and once it took me to a blue screen with movable arrow cursor, but it never went beyond this.
is there anything else left to try before taking it to apple?
any help would be greatly appreciated.
thanks,

I'd call Apple support at this point. You'll need
to put this issue on the record.
Call U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
The wait may be long for an agent to come on the line
so expect that and have some other stuff to do in the meantime.
If you have the applecare protection plan, I'd ask about "onsite"
service.
I like your work ! Good luck !

My iMac won't boot past grey screen and it didn't come with a os x disk

My iMac won't boot past grey screen with apple. I've tried booting in safemode but that didn't help and my iMac didn't come with a os x disk.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

IMac Does not boot past Gray Screen

iMac does not boot past Gray Screen. 2008 24" Intel iMac running Mountain Lion with 1TB hard drive.
Problem started yesterday while I was web surfing, and my iMac frooze and shutdown. I rebooted and could only get as far as the gray screen.
On bootup the following things happen:
Startup tone
Gray screen with Apple, and gear spins below Apple.
Once the gear stops spinning, nothing happends.
Troubleshooting steps I have tried:
removed all devices connected to iMac and rebooted, but same symptons occur.
booted into Safe mode and run disk utilites.
     Disk Utilities found no errors on the drive, but did find two permission issues that it was able to fix.
          First permission issue:
                   "Group differs on library; Should be 0; group is 80"
          Second permission issue:
                    "Permissons differ on library; Should be drwxr-xr-x; They are drwxrwxr-t"
Disk Utilities says it fixes these issues and then I reboot, but get the same problem.
I reboot back into Safe Mode and run Disk Utilities and it discovers the same problems listed above with Permissions. It says it fixes them, I reboot, but the same problem occurs. Its as if we are stuck in some sort of loop process.
Booted into Single User Mode and ran the following command:
     /SBin/fsck -fy   it reports back, Volume Apprears to be ok.
I reboot, same issue !
Performed SMC Reset, Rebooted, same issue
Performed PRAM Reset, Rebooted, same issue.
Booted into Recovery Partitioin (Command R) and ran disk utilities. It found the same permission issues listed above. It fixed them. I rebooted. Same problem still.
While in safe mode, I preformed a full time machine backup.
I am out of ideas. Any help would be greatly appreciated.

Hello,
I reboot back into Safe Mode and run Disk Utilities and it discovers the same problems listed above with Permissions.
You can ignore repeated "fixes" it's not really a problem, if it says completed repairs that's all that's needed.
Luckily it boots in Safe Mode, here's basically the steps to try to find out what it is...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
Though I'm suspecting some corruption to your OS at the moment.

Since installing Yosemite I have had difficulty in starting my iMac. Either its a blank screen or I get the rainbow wheel.

Two days ago I installed Yosemite. On start up I now get either a blank screen and have to power down by holding the start button or I get the rainbow wheel which takes ages to clear.

When I boot windows all I get is a blank screen, althought the windows splash sound does play, so im not sure if this is actually a boot issue or perhaps just an issue with windows so wanted to check here first.
Thanks

If you're hearing the splash noise, it boots. No issue with GRUB.

IMac 21.5" boots to white screen with vertical blue lines/bars then locks up

iMac 21.5" (mid 2010) Intel Core i3 4GB RAM with Radeon HD 4670 boots to white screen with vertical blue lines/bars:
Then it locks up after a few minutes, at which point the screen changes to white with these blue symbol things all over the screen:
If boot to Safe Mode, it still has the white screen with blue lines/bars, but eventually loads the login screen and I can successfully login and get to the desktop, but even that has the bars/lines.
Eventually, after enough restarts or hard shutdowns it will boot normally with no video/display issues. I've run disk checks, did the SMC and PRAM resets, checked logs (that I know of), and have even taken it completely apart, cleaned it out, reseated everything, put it all back together, but no change. I've read a few other posts about similar issues (but not quite the same video issue as this) where people had the logic boars replaced or reinstalled OSX, but that didn't always fix it. Any ideas? Has anyone seen this issue before? Thank you.

Is this a dead disk?
Very well could be.
If you can not startup from the Hardware Test, in Safe Mode or from > OS X Recovery as discribed in the Support article's.
Dig out the original Install Disc set that came with the iMac and do one of the following.
1. Attempt to Repair the Hard Drive.
Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (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.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Mac OS X volume.
Click Repair. Disk Utility checks and repairs the disk.
2. Run the Hardware Test from the second Install Disc.
1. Insert Disc 2 and Startup holding the D key.
2. Select the Extended Hardware Test.
Then if you still can not get anything going, you need to contact your Local Apple Store or AASP and make a Service appointment.

Toshiba L355 Boot up Blank Screen

My laptop top boots up to a blank screen. The following lights are visible battery and power. I can hear the fan going but the screen is completely blank. I've tried taking the battery out pressing the power button etc. with it plugged in without battery all that still nothing. I have let it sit for almost a few days nothing, I'm not sure what the issue is can someone please give me a little insight. Thanks

ok, I tried to recreate the issue using my new L355 that I just picked up. I wasn't able to get the same LEDs to light up, mine always showed AC input, Power, and Battery Charging. When you plug in your power cable, does the AC input LED light up, and your battery light come on either amber or green? Does the fan come on high speed? If your AC input LED does not light, then that would indicate that either your power brick is bad, the internal jack is bad, or there is an issue with the motherboard.
I pulled the RAM out of my L355 to simulate RAM that isn't recognized. When I did, the 3 LEDs mentioned above lit up, the screen did flicker, but did not turn on. The CPU fan was running at high speed.
My first suggestion would be to try reseating the hard drive. Always unplug the cord and remove the battery prior to opening any of the panels. There is a panel on the bottom front of the laptop with 2 screws. Unscrew those screws, and the panel will hinge open(they are capture screws, so they wont fall out). There is a black cloth band on the hard drive caddy. Pull back to pop the hard drive out. Then push it back in firmly to reseat it. Power it up and see if it comes back to life. If not, remove the hard drive completely, and power it up. If it comes up with the hard drive removed, then the hard drive is the issue. If the issue remains, then put the hard drive back in, and put the cover back in place.
Next, unscrew the capture screw in the center panel. Pull the panel off, to access the RAM. The RAM is removed by pushing the silver tabs outward away from the RAM. The RAM stick will hinge upward. Remove and reseat both sticks. Try to power it up. If it still does not power up, then try just installing 1 RAM stick. If that does not work, swap it out for the other stick. This will check to see if you have an individual stick of RAM that is bad. It's highly unlikely that they both would go bad at the same time.
If none of the above suggestions point to the issue, then the issue is internal, and would require service.

Windows 7 64bit
This is a build working perfectly for over a year.. well one day my mom turned off the computer when I got home it wouldn't boot I disconnected/reseated everything and was able to figure out if I didn't have my dvd drive hooked up it will boot perfectly fine. I should note that the drive shows up fine in the bios and that with a pata hard drive it will load windows fine.
I've tried 2 pata drives and 1 sata drive all working/tested in other machines .. and it stops at the same exact spot every time right after the bios and before the Windows logo would normally pop up it will just sit on a black/blank screen forever. I have never heard of a issue like this where it wasnt the ide channel going bad or the drive itself but since a harddrive on the ide channel works i assume its good.
I didnt know if i should post this in the windows 7 64bit forum or this but im leaning towards motherboard as the issue because it still freezes at same exact spot even with no hard drives connected , so I couldnt boot anything from the dvd-drive. I'm also thinking its the mobo because i had it repaired a year ago, see my old thread here
https://forum-en.msi.com/index.php?topic=127312.msg958264#msg958264

Satellite A300-1LT won't boot up - blank screen & no HDD activity

I had a problem, touch pad won't work.
I found on internet solution to shut down computer, take out battery, wait a little bit, and start again.
That is when my problems start.
When I placed battery back on, i turned on the laptop.
Blank screen (nothing happens), led indicators are on (except for hdd), cd drive tries to read but nothing happens, and the fan is on.
I tried everything that I could find (wait for 30 min, take battery out, start without battery, etc...) but no luck.
My lap top is Satellite A300-1lt, and I had it for 2 months.
I don't want to take it to service, unless it is really necessary, because i really need it now, I can't wait for weeks until it is returned.
Can please somebody help me out, Im desperate....
Thanks in advantage...

Connect your notebook (with battery) to the AC power supply and leave it an hour and try to start your notebook again. If notebook starts again leave it running until the battery will be full charged again.
I hope it will work properly again. I have had similar problem with my Satellite A300-1LI and I have do this. Now notebook runs perfectly with and without AC adapter.

IMac G4 OS 10.5.8 booting issues, blue screen

I'm trying to remotely help my mom to solve a big problem with her iMac G4 (2007 vintage.) It's running Mac OS 10.5.8. Everything was fine until a couple of weeks ago when it started refusing to boot. It starts to boot, you get the Apple and then it continues on to the blue screen, and never progresses from there.
It WILL safe boot, and I've tried all the things I can think of... disabled login items, reset PRAM, used Disk Utility to check the HDD and repair permissions. But it won't boot in normal (non-safe) mode.
So I decided the only solution would be to archive and install Leopard again. I figured the hardware was mostly likely okay, since it would safe boot. She couldn't find her Leopard install disks so I sent her mine.
But the system won't successfully start up from the install DVD. It does read from the DVD and starts the boot process, but again it hangs at the blue screen and does not continue beyond that.
I am not sure what to try next... I suppose it's possible that there some bad RAM or something which isn't accessed during the more limited safe boot but is used during a regular boot and causes the hang. It seems like the HDD is probably okay since it consistently safe boots without a problem. What else can I try?
Any suggestions are greatly appreciated!

The test as run from the original install-restore disc #1 should be accessible
when booted per instructions on the label. Usually, there's the method on how
to use the Installer (C key on boot) and also the other is there, on how to use
the same DVD to boot the Apple Hardware Test (perhaps Opt key.)
With an older computer, there is the chance the hard disk drive may be fading;
due to use and age factors. However, one could still (maybe) find information
on what else may be going on, IF the error and crash logs in the Console utility
could be accessed, then read through, by someone with technical knowledge.
The Console logs may be accessed if the computer can be started in SafeBoot.
And there are several, in there; some would not apply. Also, they're rather cryptic.
Sometimes, a section of a hard disk drive where the boot information is stored
could be damaged; or the Directory may be corrupted, so a third-party disk
utility on its own DVD or bootable volume can be helpful to correct that aspect.
Or to totally erase, zero, partition map and reformat the hard disk drive may do
to attempt to restore function of the computer to normal; while wiping user content.
A backup of content could be made; even a clone copy to an external, then that
could be transferred (via another clone, using Carbon Copy Cloner, etc) and if
the computer were wiped, that bootable clone could be moved back. Or, should
the internal drive be bad, the content of the computer can be put into a new HDD.
{The 'pizza box' iMac with the G5 PPC processor, had a few known issues in
certain models, some due to heat and other component failures; so the hard-
ware test may be helpful. So would an inspection of the power & logic circuits.}
Anyway, sounds like 10x the trouble at a distance, helping someone figure out how.
Good luck & happy computing!

IMac won't boot! (gray screen of death?)

Hello,
I just had a kernel panic on my main iMac computer, so I had to restart it...
When it logged in automatically, it restarted again (by itself)...
Now, once it booted, I'm staring at the horrendous Gray Screen of Death/Doom...
No apple logo, no loading wheel, nothing... just a blank gray screen.
Please help! I have no idea how to fix this!
Thank you. All help is greatly appreciated.

Hi mik.e245
Pop in the Install Disk 1 that came with your iMac and run disk repairs as described in the articles below:
http://kb.wisc.edu/helpdesk/page.php?id=3810
http://docs.info.apple.com/article.html?path=DiskUtility/10.5/en/duh1018.html
