IMac :: Shows Black Screen - Booting With Windows Partition

Nov 22, 2010

Just installed Windows XP using bootcamp and usually no problems switching between operation systems. Recently started using an USB modem for my wireless internet connection. Internet works on both Mac and windows through the modem. Now the problem is whenever I restart or switch on my computer, it shows a black screen if I choose windows partition to boot. No problem if I start through mac partition. If I unplug the USB modem, everything goes fine and I have to plug the modem after starting windows. Is there any solution so that I can permanently plugin the USB modem and avoid booting problem?

Windows On Mac :: Black Screen With Underscore At Top Left Corner / Booting Into Windows 7

Oct 11, 2009

This only happens when I choose to boot into windows. The screen sort of hangs for about 20 seconds in a black screen with an underscore at the top left corner before even starting to boot into windows. I know its normal for this to happen for like 5 seconds tops, but this is happening for about 20 seconds and its dreadful trying to boot into Windows 7 because it takes so long. When windows is done starting up i don't even get any messages saying startup failed or something like that. This is so annoying that I even reinstalled everything but the same thing happened.

IMac :: Secondary Monitor Not Working - Only Shows Black Screen

Jun 10, 2010

24" iMac running 10.6.3 and having some issues all of the sudden with my secondary monitor. It detects the display and the monitor comes out of standby, but only shows a black screen. Tried it with another monitor to see if that was the issue but it's not. Seems as if the iMac is sending bad video signal out... Couldn't find anything similar on a quick google search so I thought I'd try here to see if anyone had any similar problems.

MacBook Pro :: Its Not Booting Up, Shows White Screen?

Jun 19, 2012

My MBP was working fine and then froze while I was on the internet.  I turned it off and on again by holding down the power button.  It powered on and froze on the white/gray screen with the Apple logo with the spinning wheel underneath it.  I restarted it again by holding down the power button.  Now it freezes on an all white/gray screen.  I've tried starting it with the disk in it and holding down the "C" key and starting it and holding down the shift key after I hear the start up tone.  Neither have worked.

MacBook :: Black Screen After Booting?

Feb 13, 2012

A few times now, maybe once a month, I've restarted my (first generation, 2006) Macbook and gotten nothing but a black screen, while the computer seems to be continuing to boot in the background. The boot-up sound plays, and if I leave it to finish, the screen goes from black to a dull grey, and I'm able to shut it down by hitting the power button and pressing Enter, as if the shut-down dialogue screen has appeared. The pattern so far seems to be that if I shut down down mid-boot, by holding the power button, the next boot will still have a black screen; but when I let the boot finish and shut down from 'within' Mac OS X, the next boot works normally. I restart the computer once or twice a week, and this only happens occasionally--but it has been happening repeatedly.

Windows On Mac :: BootCamp Partition Not Booting

Dec 18, 2010

I've been running Windows 7 64 bit on my MacBook Pro for many months now and have had no problems with it, however last week my BootCamp partition decided not to launch anymore and instead it goes straight into Startup Repair. Startup Repair is never able to find a problem and shuts my computer down straight after. Now I'm stuck using OS X without the programs and such I need.

Apr 25, 2012

I Upgrades to Lion last year. Two months ago, suddenly the screen of the iMac went black. I tried to boot but it didn´t. After waiting one day, it worked and i made a backup and I installed Lion again but this time not updating.It worked, never happened again till yesterday. The screen went black, I still could listen to the song that was playing on iTunes but after a while it crashed at all.Hours later could start the computer doing everything i read here: SMC, PRAM reset, start with D, with shift.... and i made the backup but when i was going to install Lion again it went black again and I couldn´t restart my iMac.I´m afraid it´s the NVIDIA card, but i can´t be withouth the computer some weeks. Is there anything i can do to fix it or to boot at least?

Windows On Mac :: NTFS Partition Shows Up As HFS+

Feb 5, 2010

I'm working on an iMac that has Vista (yuck!) installed on the hard drive. When I boot up and external with OSX, the internal partition is not recognized by Finder. Disk Utility claims its HFS+ but will not mount it. When I boot the machine with GParted, it also claims the partition is HFS+. It looks like Vista was installed over the OSX partition and the GUID still thinks its HFS+. Is there a way to correct this so that it shows up as NTFS? I would like to use GParted or WinClone to back up the partition.

MacBook Pro :: Dual Booting With Windows XP Black Edition?

Aug 9, 2009

So just got my new MacBook Pro yesterday and loving it! I just got VMware Fusion and have a quick question (just don't want to mess anything up).

I have the Windows XP Black Edition image file, when I hit "Continue without Disk" on Fusion, next options are "Use installation disk image file", "Use existing virtual disk" or "Create custom virtual machine".

If I just have the .iso, what option should I go with?

MacBook Pro :: Not Booting Up - Blue Then Black Screen Appearing

Jun 19, 2012

I have a MacBook Pro Core 2 Duo 2.5GHz/250GB HDD/2GB RAM that won't turn on, unless I leave the power button pressed, in which case, as you all know, the computer turns off again. It started about 3 days ago. Set the computer to sleep, shut it closed, took it to another room and opened it. The MBP gave me the blue screen, then black and then... nothing.At first I thought it was the HDD, but now I'm having second thoughts. I now think it's the cpu fan.

Windows On Mac :: Partition Errors In Bootcamp When Booting Vista?

Mar 25, 2009

I did the Bootcamp thing, partitioned the drive and installed Vista. Everything went well and Vista works just fine. But everytime I boot into windows, I get partition errors before it boots.

For example it says:

"Warning: Unrecognized partition table for Drive 80. Please rebuild it using a Microsoft-compatible FDISK tool (err=4)"

It will come up 3 times, and then boot into Vista. Both OSX and Vista are working fine, but something is definately wrong though since I am getting this error.

MacBook Pro :: Keeps Freezing Up - Shows Black Screen On Startup

Mar 12, 2012

Recently my Mac has been extremely unstable. It keeps freezing up and hanging for no reason. Initially a 3 beep would sound off, I ran some tests like the apple hardware one and realised that one of the rams was bad. I bought 2 new sticks of ram and replaced it. Following which, the mac still freezes up and a 3 beep alarm sounded off again.

Currently, I'm trying to turn it on, no 3 beep signal is sounding off but the Mac either keeps freezing and showing a highly pixelated screen or a black screen surfaces. There is some sound coming off from the laptop as well.Each time I switch on the system, it just shows a black screen with no display.

The Mac is a 15'' 2.66 MHz i7 which was manufactured in the mid 2010s.
The 2 new sticks of ram are Strontium 1066Mhz 4Gb x 2 sticks.
In the initial stages: kernel panics were common as well.

MacBook Pro (15-inch Mid 2010), Mac OS X (10.6.8)

OS X V10.5 Leopard :: IMac Screen Went Black - Starts Up With Black Display

May 24, 2012

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

IMac :: Booting - Cannot Get To Login Screen

Sep 6, 2009

When I turned my iMac on this morning (iMac G5 PPC 10.5.8) it went through all of the "normal" steps (gong, grey screen, apple logo, progress wheel, blue screen) and stopped at the blue screen. Thinking it was just a fluke, I shut the machine down and restarted, only to have it stop at the blue screen again.

After disconnecting everything going into the iMac except the keyboard and mouse, I attempted to boot into safe mode but it stopped at the blue screen again. I tried single user mode too but I didn't get any further than the blue screen.

Next, I flashed the PRAM (big gong, single quieter gong) and afterwards it came to the blue screen.

I reattached my external drive and selected to boot from a 2-day old backup. Using the backup I was able to log into both my regular account and my "test" account (without login items).
