View 3 Replies View RelatedThis just started yesterday (May 31st). I keep everything updated as it comes out and nothing new has been installed in the last couple of days.
When I need I wake up my iMac (now requiring a keystroke or mouse press instead of just moving the mouse), the screen comes up black, but the cursor is there and moves around fine.
It stays black for a while (15 seconds or longer, but it feels like forever) and then it finally comes up completely.

Middle of last month I bought a 20" IMac. Everything was fine up until about 1 week ago when the screen went black. I clicked on the mouse button several times only to have a password box pop-up. After filling in the response, all was fine.
Next, same scenario but the password box didn't appear any more. The only way to get the screen back was by a forced restart.
I turned off the screen saver, set the 2 controls in energy server to off, unchecked the box at the bottom left & put "auto login" to to on the Accounts window.
Problem continued.
Next move was to zap the pram, this was 2 days ago. The screen didn't go black but often asked for my pw. It's now back to its beginning phase which is a forced restart !!
I was told that it was due to Leopard 10.5.2 & am considering going back to 10.5.1
Black screen on my iMac, how can I get it back to log in screen?

What is happening to my computer. This is the 2nd time it does this: all of a sudden the screen becomes black with reverse fluo colors.
I have to force quite with the push button & restart it. I repaired the permissions & restarted it. It's working again, but I am wondering if I have an alien in it.

After I updated to 10.5.7 I experienced a few issues. First of all, after the initial update I restarted the computer than I got a black screen that said "No bootable disk found" or something along those lines, this was fixed after 4 restarts. Also after the update i experienced problems while trying to browse the internet. Some pages would load, but others, like google, and theMacrumors "forums" page, wouldn't load completely. I was just wondering if anyone else had experienced issues like this or anything similar.
View 13 Replies View RelatedI have a 27 inch desktop. Upon turning the computer on within seconds the fan comes on. Then it goes to a high fan. Then it goes to a black screen. Then it shuts off. Then if you click the mouse it will come back on. This cycle repeats itself every 5 seconds. Only one time in the past month did it turn on normally and run for me.

I would like to make my usb memory bootable. Is it any way to get the drive to show up in startup items in sys.prefs? I have tried with fdisk, hdiutil and diskutil but have not been able to select my drive. I thought it was going to happen with fdisk. Typing fdisk /dev/disk1 gives me this.
View 6 Replies View RelatedI tried to install ubuntu with bootcamp on a different hard drive. Something happened and now when I turn on my computer it says no bootable devices. It doesn't even see my OSX hard drive. I tried booting up my computer and holding down option. It doesn't work. I have a wireless microsoft keyboard. Is it not letting me hold down option because the computer finds the wrieless keyboard to late. Some one said u have to hold down the option key before the mac sounds happens. The keyboard lights don't come on till after that. Should I get a USB keyboard? I have to press the start button on the keyboard to act as the option key when I'm in osx. Would the computer know that the start key is the option key on boot up?

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 just recently purchased a Macbook, and I created a bootable backup of the system. The macbook boots from the backup, but when I try to boot from the backup on our G5 and also our Powerbook G4 it will not work. The G5 does not even see the bootable partitions I created, and the G4 sees them, but when I select the partition to boot from, the computer just restarts and boots from the Powerbook hardrive. We are having to send the Macbook back for some small power issues, and we need a bootable backup of this sytem that works. Does this have anything to do with the fact that the Macbook is an intel based computer and the Powerbook G4 is not? Also, the macbook is running Snow Leopard, and the Powerbook is on Tiger.
View 4 Replies View RelatedI first installed Windows XP when I got my early 2008 Mac Pro. Boot Camp was probably beta back then, but I cant say my experience has changed much through Vista 32 bit or now Windows 7 64 bit. The way to dual boot, holding ALt during boot, has worked 1/10 times. Literally. The boot symbols are usually delayed, so I know when I choose the win partition, it gives me the "No bootable device" error. Two times have I had heavy OS X crashes after these boot-up "games". This last time I had to completely reinstall OS X (or upgrade to SL). How could this be, im not even booting into OS X when I am trying to boot into win.
I even have a separate hard drive for my Win partition. Not to mention the stream of driver issues you encounter when you finally manage to get inside Windows. I actually had my apple wireless and mouse working in Windows 7, but then I installed Boot Camp drivers of the DVD, and now theyre dead. I know. Its Windows, why would I miss it? Gaming or apps, regardless. Apple shouldnt include a program that functions so poorly, if they insist on higher standards elsewhere. It only reflects badly upon them. I consider myself a decent level mac user, venturing into command line troubleshooting if needed. But BootCamp remains a mystery to me.
I have the latest 17" i7 macbook pro and installed windows 7 64 bit on 100 gb partition. Long story short, I decided to delete the partition for now and install another time. It deleted fine, but every time I turn the computer on, it will load and say " no bootable device" but if I turn on holding option, the mac partition shows up fine and loads normally when I click on it. I just need help completely getting rid of the partition. My Mac hd says 500gb capacity. So its not partitioned any more.

Couldn't get testwin or chkdsk to repair it (under windows)Anyway, got him to replace the hdd and he also wanted windows on there. Either XP or 7 on there.Upon trying to boot from the windows 7 or windows XP disc, I get "no bootable device found - insert boot disc and press any key"Thus tried booting while holding C down, and tried booting while holding "option" down", problem is..i think his bios is corrupted as well. I get a white screen upon powering up. No mac logo. When I hold down "option", the mouse arrow pops up but nothing to click on.

This is now few days I try to install Win7 from USB on MBP 15 i7. I used the Windows 7 USB/DVD Download Tool Help to create my USB stick. I was successful to install it on my brothers 27" iMac using the same process but Im having problem with my MBP.I create the BootCamp partition 100GB and installed rEFIt.Each time I try to boot of USB I get: No bootable device -- insert boot disk and press any key
View 4 Replies View RelatedI always get this error when I try to boot up to my Windows on Bootcamp: No bootable device -- insert boot disk and press any key
I installed Windows 7 through Bootcamp and I got everything installed perfectly!
I partitioned my Mac's hard drive into 3 before the Windows installation:
-Mac OS
-Data For Windows
-System for Windows itself
It all worked fine and i could drag and drop anything into that Data Hard drive through Windows very easily. However, when I came back to my Mac OS and partitioned my Mac Hard Drive into 2 parts(Which makes 4 partition now) and tried booting back up to my Windows, it gave me that error. I then decided to re-partition it like before which was Mac, Data and Windows. Booted it back to Windows and it gives me the same error again. I have an attached Picture showing how my partitions look now. Does anyone know how to fix it? I think it's because what my Windows is booting from is the Data Hard Drive but not my Windows 7 Hard Drive with the OS on it. Is there a way to change it's place or to tell it which Hard Drive to boot from?
