Black screen with white flashing line on startup

~computer info~
Mac OS X Version 10.6.7
2.66 GHz Intel Core 2 Duo
4GB 1067 MHz DDR3
24 in. Montior
Startup disk: Macintosh HD
~Partition info~
FAT32 Windows XP
~issue~
Hello; I've recently encountered a problem with bootcamp that I can't find a solution to... Every time I start up the computer in boot camp, all I get is that black screen with the white flashing line. It comes up, goes to a plain black screen, then quickly comes up again. It never stops, either. I've let it run, and it won't finish.
I've had the partition for MONTHS now, and nothing like this has happened. I've had it since I upgraded to Snow Leopard awhile back, and needed to re-partition the drive. I literally had been using it the day before it happened, and the only thing that happened was that I got that "Windows Security 2011" malware, but I got rid of it fully (As I've gotten it 3 times this month). The other two times I got it, it didn't do anything. I fixed it, and went on with life. But is it possible that it broke something in the partitions inner files this time?
I ran disk utility, and it said the partition was broken. After verifying it and confirming this, I did "Repair Drive", as it allowed me to. It finished with no errors and said it completed, so I tried to go back into the partition, but it gave me the same results.
To be honest, most of my stuff is on my External Harddrive, so re-doing the partition is only going to be time used to me. But I still DO have things on there, and it'd be a pain to transfer them back and forth between the Mac and Windows partitions... I'd really like to know if there's anyway to fix this, or if it's just going to fall back to me re-partitioning the drive...
Thanks for the help in advance.

That blinking line is a "cursor." It's only supposed to show for a second or two as your iMac switches to and then starts Windows. But as you indicate here, it's not getting past the cursor..
Disk Utility can repair FAT volumes, but it cannot correct issues caused by corrupted items which, if the volume was repaired, there may be some.
Since we are dealing with a Windows boot partition, it's entirely possible that the repairs inadvertently corrupted the data Windows needs to start and run. It's also posible that Mac OS, in fixing the Boot Camp volume, overwrote the existing boot record in the Windows partition with a generic, though non-bootable version.
Windows' own CHKDSK should have been used to make the repairs rather than the OS X Disk Utility, which would have avoided this worst-case scenario in data recovery. CHKDSK has a special version of itself on the Windows disc, which may be accesed by using the Windiws Recovery Consile upon pressing R during the "Welcome to Setup" screen.
Though it appears ftom my position here that you will need to reinstall XP, it may yet be possible to recover data that hasn't been copied to the external HDD. For this task, I'd like to recommend that you start up in Mac OS for the time being, and pull any new or changed items from the Boot Camp volume except for installed software; the latter are nearly impossible to transport with reasonable accuracy, and should instead be reinstalled.
Once you have what you need, format your Boot Camp volume and reinstall Windows, this time selecting NTFS as your filesystem. NTFS is the preferred option for Windows in general, thiaks to its innate file access controls as well as the ability to compress or encrypt data "on the fly." NTFS can be read by Mac OS X, but not written from it, thus NTFS volumes cannot be altered except by Windows itself.. But it is also a requirement if you plan to upgrade your unit using Windows 7 in future.

I repaired a cracked iphone 5c screen now I have a black screen with a vertical blue line on the left hand side of the screen. please help!!

Hi all,
Please help, I repaired an iphone 5c and have now tried two different lcd screens on it but all I get is a black screen or a black screen with a vertical blue line on the left hand side of the screen. I definitely have the cables connected properly etc and before I repaired it the phone had a cracked screen and there was a picture on it.
I have tried hard reset and nothing. I have tried connecting to iTunes but it asks me to confirm on the iPhone which I can't do as there is nothing on the display. I have tried randomly pressing all over the screen but it doesn't work. So I can't even try restoring it on iTunes.
Please help any advice will be appreciated! I successfully have repaired iphone 4's and iphone 5 before but this is the first iphone 5c.
Thanks.

Since you were successful the last two times, I'm sure you will figure it out.

I inadvertantly dropped my iphone 3 and now have a white screen with green vertical lines to the right. It won't sync with itunes due to an error. What can I do?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If it does not resolve the issue, the device is permanently damaged and will require replacement.

Black Screen with white text at startup (??)

Hello All:
I have a 2010 15" MacBook Pro, just got it in June. Had to send it in for a logic board replacement and now have it back. Everything works great except now instead of having the standard Apple greyish startup screen, I have a black screen with white text that scrolls through all of the startup stuff. I figure they changed some line on a plist somewhere so they could watch the startup and make sure everything was OK, then forgot to change it back.
Although I know it is good to know what's going on under the hood, I would rather it started up the regular way. Anyone know how to switch it back? I would call Apple, but would rather not sit on the phone for a long time for what I believe is probably a very simple fix. I did a search but couldn't find my problem listed....
Thanks everyone...

Kappy:
Thanks for the reply. I looked at the plist, but the -v was not there. Here is a copy of the plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel Flags</key>

</plist>
At least I know what it is called now - a "verbose startup".
Again, thanks for the help. Learn something new every day.

I don't know what's wrong with my 3GS. It only shows the black screen with white apple. Turning it on then off doesn't help.

I don't know what's wrong with my 3GS. It only shows the black screen with white apple. Home button and turning the phone off then on doesn't seem to do anything.

Thanks Lucas,
I've tried doing that with no results. Same screen keeps showing. Maybe it'd be more helpful if I told you a bit more info. My phone was randomly playing music, and the voice control would also suddenly start without me touching the phone. Then I let the battery die and started to recharge when on the screen it indicated to plug into my computer/iTunes, I tried to restore but was getting an error message (can't remember what it said now). Battery died and now my current issue of the black screen with white apple. I'd love to be able to restore my phone but now its not showing as a device on my iTunes. HELP! Any other suggestions?

Black screen with white apple logo won't go away! Help please.

Last night I turned theipod completeley off and restarted it. The black screen with the white apple logo came on and hasn't went of since.
I've tried everything I could find in the forums and on the support page.
iTunes will not recognize my ipod which has continously tried to start up again every 5 minutes.
I don't know what more to do, ANY help would be greatly appreciated.
Thanks
Dana

I did try that. When I do that the red slider bar to turn the ipod off doesn't come up.
Its still trying to reset itself but won't go any farther than the black screen with white apple.
Thanks

Black screen with white writing on boot - then nothing...

Ok, this is a long story, but here's the abridged version;
I have a mac mini - the old PPC version. It has just come back from being repaired - replacement logic board. However, repaired it is not. Every time i try to start it up, I get a brief white screen with grey apple logo as normal, and then a black screen with white writing on. The writing is exactly the same text as you can see in the console system log. It gets about a page-full through this, and then goes completely black. No video at all.
However, the machine is still working in there - I know this because I'm typing on it now via VNC. It is perfectly happy and all. It just does this weirdness start up and then no video.
My question is twofold:
1. The company that repaired it claims that it booted fine before they gave it back to me; however, it hasn't since I've had it back. Could the boot behaviour be some kind of diagnostic thing they left on my machine, or a mode they left it in. If so, how do I get rid of it?
2. Failing this, does it sound like my vidoe card packed up maybe?
Thoughts, solutions, etc., most welcome!

Have you
tried to simply do a clean install of Mac OS X and
your other software? I normally find that this fixes
90%+ of all unexplained software related issues.
I could, but (a) I'm not convinced it's not related to the replacement logic board and thus a hardware issue, and (b) I can't see to do a clean install because it has no video signal

Black screen with white circle every 5 seconds, after water damage

my ipod touch (3gen.32gb) had water damage 3 days ago. now as it dried, i connected it to itunes and restored, but it keeps showing black screen with white circle every 3-5 seconds. could this be a software problem or is it all because of water? i put it in recovery mode, and restored again, but it did not help, is there anything i could do to stop it ? thanks

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Hi there did you end up getting this resolved? I have the same exact same issue with my Ipad 4 when updating to 8.1.3....frozen on the apple logo. Tried resetting as advised by other users but just goes back to the same logo. Tried connecting to iTunes but device is not picked up at all. Left it over night to run flat hoping charging might kick start something....but when I put on the charger it shows the battery charge icon but won't actually charge it. It's really doin my head in trying to find a fix - cheers Morgan

Macbook Pro boot shows black screen with white text cursor

Hello,
I have a MacBook Pro 7,1 MC374xx/A running Mavericks. My box has two internal hard drives in it. One had the Mac OS installed to it, and the other has absolutely nothing on it. I decided to give Boot Camp Assistant a try and chose the hard drive with nothing on it to install Windows on. I also had an external USB DVD drive attached with the Windows 7 installation disc on it.
So, next thing ya know, my Mac reboots and loads a black screen that says "Memory Overload." I take out the external USB drive and restart. Then it said, "No boot devices found." Now for whatever reason, it's just a black screen with a white text cursor.
What the heck happened?
I selected command R and confirmed that I installed Boot Camp on the right hard drive (the drive that did not contain my Mac OS). Then, I completely erased everything from the drive with Boot Camp on it. But still..black screen with white text cursor.
I have no Time Machine backups available so I'm forced to reinstall the OS. Any idea why this happened? It seems I must have attempted to install Boot Camp improperly. Any ideas or instructions on what to do now or how to install Boot Camp successfully on the Macbook Pro I own?
Earnestly,
Speck

Ipad has black screen with white bar

My ipad2's screen has gone blank. after leaving it uncharged for a good 18 hours. I switched it on to see a blank, black sceen with a white bar moving downwards accross the screen this fades to black.
I have tried charging it for a good 7 hours as I thought maybe the battery has run down and caused this.
I have also tried resetting by pressing the on/off and home button together for 10-15 secs but no luck.
My ipad still synches to my imac okay. I have restored it to factory settings. This didn't help the problem either.
This actually happened when first took the brand new ipad out of the box and tried turning it on for the first time. But it revived itsself after synching to my imac and being on charge for a few minutes. The support technition I spoke to at the time didnt really know why it did this but suggested it was a very low batterry issue. Although I am inclined to think its something else, now its happened again and charging does not seem to work.
Has anyone had the same problem? If so what did you do? Any suggestions on how to fix it would be gratefully recieved.
Thanks
P.S. I am running iOS 4.3.3 on my ipad. However its not an available option in the OS dropdown for this discussion. hmmm!

I Don't know if this will work for anyone else but just FYI - after loading 8.1 on my iPad it froze for several hours on the black screen with white Apple and progress bar underneath. It would not do anything. I thought I was doomed. I accidentay left it sitting overnight without plugging it Back into the charger. I meant to but got sidetracked and thought it was plugged in. During the night the battery was totally drained so this morning my iPad was dead. I plugged it into the charger and after a few minutes the battery icon came up showing it was charging. I gave it about 30 minutes and then turned it on and the new operating system came up. It looks like it might be ok now. I can't say I recommend this, but it worked for me.
