OS X :: IMac Bootcamp - Stuck On Flashing Underscore Of Black Screen
Jul 24, 2009
I tried to install Windows 7 via Bootcamp a couple weeks back, but shortly after it failed, I deleted the Bootcamp partition in Bootcamp Assistant. However, whenever I want to boot my computer, it tries to go into the Windows Installation, but it gets stuck on the flashing underscore on the top left of the black screen. Henceforth, whenever I want to boot into OSX, I have to hold down both ALT keys. is there any way of fixing this so the iMac boots STRAIGHT into OSX (like normally)
I was going to download windows XP using bootcamp and I did everything up to the point to the point where you choose FAT or NTSF. Well the only thing there was NTSF so I decided to cancel it. It said it was going to reboot so I waited and it restarted. I ejected the disk and now the screen is black and theres a white underscore flashing. I restarted it and its still not workingand the screen is still black. How do I fix it? I already tried the ctr+option+p+r thing wiht no luck. Do I have to reinstall OSX again?
I am running OSX 10.5.8. A little while ago I successfully Boot-Camped my hard drive and installed Windows 7, but i recently got a new hard drive. I copied over my OSX partition successfully, but didn't copy over the Windows partition. On my new drive I went through the boot camp assistant and created a partition and inserted the Windows 7 disc. But when it restarts, it just seems to hang there- it's just a black screen with a blinking white underscore(_).
I have been told that because I copied over my OSX partition it didn't set up the MBR on the new disk, is their any way to fix this? (besides doing a clean install of OSX) Are there any software or guides available to help me fix this?
I was playing Diablo II and my screen froze, and the same half second blip of sound kept playing over and over. I couldn't even force quit, so I held down the power button until it turned off.
Now, it won't turn on. When I press the power button, there is no chime. Oddly there are an inordinate number of fan wooshes. Like, I hear a woosh from the right, which is normal, but then I hear a woosh from the left, then another in the middle! I am being bombarded with wooshes!I've tried holding alt, or holding shift, or holding alt+s while starting up. No dice, although I do get fewer fan blasts, which is normal.
I recently installed Windows 7 Ultimate on my 2007 iMac, and so far everything is running flawlessly EXCEPT that every time I boot in to Windows I am greeted with a flashing underscore for about 55 seconds before the boot process continues. Has anyone any idea what the cause and solution to this little irritating problem might be? I used the drivers included on the SL DVD in case anyone is wondering. Here is a short video clip showing the whole boot process: [URL]
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.
I decided I was going to install XP on a bootcamp partition tonight and everything went fine until I installed the Bootcamp 3 software. After installing the Bootcamp drivers the machine rebooted and I ended up with a black screen in Windows. I did hear the XP welcome music so I figured it was a display driver issue. I rebooted into safe mode and deleted the ATI 4850 driver and restarted. After removing the bootcamp driver everything was normal again other than the fact that I only had the default Windows drivers running.
What am I doing wrong? I installed XP off of an XP disc with SP2 already on it and ran the Bootcamp install off the Snow Leopard disc. Finally, not sure if this matters, I am running one of the new i7 iMacs.
I've now properly installed Windows 7 to my MacBook, but now I'm getting this problem and can't find a fix. Basically, I turn my MacBook on, select Windows, and it leaves me at a black screen with a flashing underscore for 45 seconds before it actually begins to do anything (making boot times unbarably slow). This is seriously annoying me, but it doesn't seem to have a fix. Edit: Oh, some details. Windows 7 Ultimate (64 bit), MacBook Pro 13" (2009), Snow Leopard installed, using rEFIt to multi-boot, bootcamp 3.0, and have never had this problem with any other version of Windows.
I freshly installed mac osx leopard on my aluminium iMac 24" I updated to 10.5.8 the latest. I made an bootcamp disk of 80gig. But all the time when i try to install windows i only get a black screen with flashing underscore. i've tried, windows xp home english, windows xp home dutch, windows xp professional sp3 the first to are sp2. And i know my windows xp home english works because i've used many times before to install windows on my mac using bootcamp. What could i be doing wrong? ive resetted the disk permissions (i have no idea how it's called in english)
iMac 27" i7 with OS X v 10.6.x when I create the bootcamp partition for windows 7 and I install from my original DVD of Windows 7. I format the partition during the install of windows 7 and on the first reboot after windows 7 first part of the install, the screen shows the Windows 7 logo and says continuing installation and then a black screen and then nothing.
I have to hard power off the iMac and then it starts over says the thing about the system didn't shut down properly and gives me the option to start safe mode etc. and does the same thing each time.
I am currently stuck on the grey screen of death with the flashing ? file folder.I have tried resetting the pram etc. and when i boot from my snow leopard disk the disk utility does not recognize my HD. Is there anything else I can do to fix this? Or try?
I received my computer back from them yesterday, but when i opened it it was COVERED in packing material? (Thats what they said anyway). After talking to them they said they would cover my laptop for 90 days from water damage or Accidental damage! Only problem is, my computer screen flashes black randomly.. Anyone have any experience with it? So far they replaced the screen and the logic board...
I have an iMac 2.8 24 inch, about Two years old running 10.5.7 , when I start the computer it shows the normal Gray screen for about 30 seconds, then the screen goes all Black , but with a small flashing white line ( _ ) in the top Left hand side corner.
It just stays all Black for ever , I then hold down the On / Off button and turn off the computer, I then hold down the keyboard '' option key '' and press the on button at the same time , then I get the option to start from the main HDD , I click the Icon and the computer then starts normally , and every thing runs ok.
Can some one please tell me what I have to do to get my iMac to start up normally again , Ive run Repair Disk permissions but the problem still occurs . Over the last few day's Ive been trying out a few new applications, so not too sure if this has any thing to do with this current problem
I installed several system updates on my 2007 iMac last night, running OS 10.7, and today I can only get a black screen with a flashing white power light when I try to start up. My computer will neither start up nor completely shut down, and my wired keyboard won't communicate either.
So my 13" MBP arrived today and unfortunately my first mac experience isn't a pleasant one. The computer wont start. I am hoping I am doing something wrong but I have gone through the step by step troubleshooting and my computer just sits there with a blank black screen. It shows that the charge is full and when I click the power button the little white light glows in front, however, no sound nor no startup happens on the screen.
I accidentally connected my wife's MacBook Air to my docking station at work today. Nothing seemed to happen so I undocked it and the computer displayed a black screen and I could see and move the cursor using the trackpad. I then tried shutting down by holding the power button for 5 seconds, 10 seconds, 1 min, etc. Nothing worked and it's stuck on the black screen so I can't use Yosemite's menu to shut down or restart. When I leave the computer idle for around a minute, the cursor disappears but it will reappear after pressing keys on the keyboard.
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?
I have a Mac Mini (2.55GHz intel duo core) and I trying to install windows xp with sp2 (downloaded from MSDN, burned to boot able disk). I created a 100GB partition with boot camp assistant, and started the installation. When I reboot the Mac Mini, and I select the windows CD icon, the screen goes black, and the Mac Mini just stops reading the disk, and stalls at the blank screen.
I am new to Mac and to forums. I am trying to install Win 7 with bootcamp. I have a new MacBook Pro and I have bought an OEM version of Win 7 Ultimate. I downloaded it and burnt it to a DVD. The DVD boots on a windows PC but I have the following when I try installing it with bootcamp 3 which came with the installed OSX 10.6: When clicking the "install windows" button the screen goes grey, the computer restarts and then the screen goes black and stays that way. The Windows installation screen never appears. I have tried many items listed in many forums but with no success. There seems to be many similar issues around but I have been unsuccessful using them.
I have a 2009 27" iMac, running Windows 7 x64 with BootCamp, and I'm having a problem when running Windows for more then 5 minutes.
After running it for about 5 minutes, the fans go CRAZY, the system doesnt get too hot though, the LEFT side of my screen starts flickering brightness, while the RIGHT side starts flickering colors. After a few more minutes of this, my screen goes completely black, I know the computer is still running, because I hear my music and the zombie killing me in Minecraft, but my screen, keyboard, and mouse dont seem to respond. I have double checked all drivers, I have updated BootCamp, and my next step was to reformat the drive, but that is my LAST resort.

OS: Snow Leopard Bootcamp Win 7, Ubuntu 9.10.Problem: I felt I would be nice to the iMac and shut it down after a hard days work. I woke up the next morning, turned it on, and it loads up past the gray screen, then goes to the dark blue snow leopard screen. From there I DO NOT get a mouse pointer. I get zip, zilch, nothing.I have let it sit over night just to make sure it wouldn't surprise me. Remedies tried:Booting to safe mode. Boots fine but when it gets to the blue screen it doesn't do anything else.Booting to single user mode. From there I renamed the com.apple.loginwindow and the com.apple.startup file. Didn't do anything.Resetting PRAM, VRAM, ram, jingle bell, any key, * key, I've tried resetting everything possible and not possible. WHY computer gods? WHY?
I'm doing this for the nth time now but because it's been so long I've forgotten how long it's supposed to take.
I ran Bootcamp assistant, and installed the windows disc. Next up is a black screen, with a flashing cursor in the top left corner.
Been like that for 15 mins. Has it crashed or is it normal? It's on a brand new MBP so I'd expect it to be faster than when I used to do it on older MBPs
Couple of weeks ago my Mac Pro died. Anyway it turned out that the mother board and graphics card had over heated and failed due to dust from building work. So I've got it back from the repair shop now, the mac side is working fine, no complaints at all but bootcamp isn't so happy. When I first tried to boot into vista after getting the comp back, I restarted, selected the bootcamp icon and then the screen just went black. The light on the monitor went dim like it does when the computer is asleep and that's it. I didn't have anything important on the partition so I just removed it and repartitioned, witch seemed to go fine. But then when I put the vista disk in to install the same thing happens again. Screen goes black the CD spins up really fast but nothing else.
I bought a MacBook Pro 17inch i7 in November 2010 and it was working fine under Snow Leopard and Lion since then. Yesterday I installed Bootcamp and it was workng also. Today when starting from Bootcamp to Lion I had a Kernel Panic (had this never before) and the screen turned black. I just have the energy cable connencted to it, the computer starts somehow (noise) but no Startsound and screen keeps black.Then I made a little mistake by inserting a LION installer DVD. Cannot get this out anymore, even when I press the trackpad when starting it. I changed the internal hard drive to be sure that the problem does not come from there. I reset the PRAM. I reset the SMC. No way to get the laptop back to work.
Info:MacBookPro, Mac OS X (10.7.3), 8 GB RAM, 30 ACD
I just tried installing ubuntu via bootcamp. I went through the whole installation process then it asked me to restart. Black Screen for 5min. Manually restarted and my system would only start to another black screen that said GRUB, with no other options. I took the hdd out that I installed ubuntu on and I would get the same problem. Did this somehow change my bios/mac equivalent. Finally was able to get into osx by holding down left mouse button on startup (nothing else would work).
I'm selling my old iMac and while cleaning the hard drive it froze. I forced shut down and when I turned it back on a circle with a diagonal came up initially, followed by flashes of that, a question mark and the apple symbol. Now it won't get past the grey screen and the flashing symbols. Â
I ran software update and got (iPhoto, itunes, Security patch) so I ran it and downloaded everything except the Intel Security Patch. So I restarted and decided to try again. Restart didn't work as it got stuck and I had to reach around and restart by holding down the power button. When it came back up, I got the white screen with the grey apple logo and the spinning clock like icon..... spinning and that is where I am stuck, left it off all night and tried it in the morning, same thing.
I did try:
-resetting pram (nothing happened) -restart in safe mode, holding down shift key (nothing, stuck on screen)
I would try to start up from the OSX disk except I have a DVD in the machine. I am thinking it was that security update that didn't download fully that is doing this but how do I get the imac, "unstuck"? or how do I manually eject that DVD to put in a OSX start up disk?
