Black screen+can't boot after installing Windows

Hello
I just reinstalled MacOSX on my MBA, then installed Windows XP Pro via Boot Camp, though I've not seen XP boot yet. When Mac restarted I chose to boot to Windows in Boot Camp. Now I just get a black screen and 'Disk error. Press any key to restart'. No keys respond and I have to press the power button for 10sec to get anywhere. but I seem to be stuck with the black screen.
any ideas!
thanks

This has happened to me on my MBP.
Did you select to format the disk under Windows setup? You have to select this, not just assume the partition is formatted. When I chose the option to format into FAT32, the rest of the install went fine and instead of the black screen, it booted right into XP.
Hope this might help.

Black screen with no cursor after installing Windows 7 through Boot Camp on Retina MBP

Hey all.
So, I have a Retina Macbook Pro (15", late 2013). A couple weeks ago I tried to install Windows 7 on it through Boot Camp.
After some struggles with trying to repair my disk with Disk Utility and having to recover the system etc, I finally managed to actually install Windows 7. However, after the installing was ready, when Windows was supposed to boot, it just gave me a black screen with no cursor. I really had no idea what to do there, I tried to do some research from google but only found answers regarding a black screen with a cursor DURING the installation. However, I managed to launch Windows in safe mode. I deleted graphics drivers that bootcamp assistant had installed, and then it worked and I got to boot Windows succesfully.
However, as probably all of you know, you can't do much without those drivers. Games, videos, overall performance of the system is kinda horrible.
After that, I wiped the whole system, Mac and Windows, and reinstalled Mac. During the Windows installation I was running on Mavericks, now I've got Yosemite. I might try installing Windows again next week, does anyone have any clue why the black screen happened? What could I have done wrong? And the most important question in my mind, in case that happens, is there any way to install the graphics drivers manually from somewhere? After I uninstalled 'em earlier, I tried to find them manually, but couldn't find any.
Thanks!

Yes, that's exactly what was the problem in the first place, I had a USB3 device. Switched to USB2 device and the installation progress started flawlessly.
The later part I didn't quite get. What are those installation methods, how could they cause the problem there? I had no problems during the installation, but after installation when launching Windows I had the black screen, and that I suppose was GPU drivers problem if I'm not totally wrong? I could hear the basic Windows system beeps etc when I tried clicking everywhere (had no cursor either, just clicking randomly), so the system was running there, but just didn't draw the picture at all.

Black Screen - Can't Boot to SAFE Mode or Advanced Options

have a three month old Inspiron 3847 with Win 8.1 that cant boot past the black screen. It does not go to Advanced Options like it should and the F8 key does not take it to SAFE mode. I do not have a bootable media to install. How can I repair this PC?

Go to run, type msconfig, hit enter, click on boot when the window opens then check safe and reboot.

Black screen on hp dv6 after installing AMD CCC for AMD Radeon HD 5470

Hi HP experts,
it started when i was playing on my pc and the screen went black and the laptop shut down. i'd reopen it and after the windows loading screen everything is black, i hear the welcome sound and when i swipe my finger on the biometric reader i hear also the sound announcing that the windows session has been started.
So i've started the laptop on failsafe mode and it's ok. i have disabled the intel HD graphic and i restart in normal mode, the display is ok. so i came back in failsafe mode and i enabled the intel hd graphic and i disabled the AMD Radeon HD 5470 and also it's ok in normal mode. the problem is when i set both of them enabled i will have a black screen in normal mode.
i have formatted my hard drive, reinstalled windows 7 64bit ultimate and i've installed all the driver from HP support web page except the two graphic drivers Intel High-Definition (HD) Graphics Driver and AMD High-Definition Graphics Driver.
Is there anyway to test if the AMD graphic card is not ok? can you confirm that it is not a haedware issue?
I'm in big troubles guys, i've work to finish ASAP, please i need help.
Thank's

Osx wont boot after installing windows dev preview.

Hi. I recently added boot camp and windows 8 to my 2011 mbp 17". Ever since the install my computer wont boot osx unless i run disk utility and repair my mac partition. Then everything runs fine untill i go into windows again and then go back to osx. Thoughts?

Do i need to make a clone or will my time machine backup work.
TimeMachine drives are not "hold the option key bootable" like a clone and with Lion there is only a "hold Command r" Recovery Partition on the same drive your trying to repair.
So to get a external source to boot Lion, you need to Carbon Copy Cloner Lion to a another new/blank Disk Utility HFS+ Journaled formatted drive. Disconnect your TimeMachine drive before doing anything and don't clone to it or everything will be erased, use another drive.
Once you have Lion cloned, hold option and boot from the Lion clone and test it out.
mcwilliamsc wrote:
I only have one external drive andni dont think a clone will fit.
Only clone to another drive with no data on it, don't clone to a partition, don't clone to a TimeMachine drive. Disconnect all other drives before cloning so you don't make a mistake.
mcwilliamsc wrote:
Also when you say c boot do you mean using a lion install disk as opposed to the install option when you boot into disk utility?
Your signature says you have 10.6.8, obviously there are no install disks for 10.7, however you can make some by "hold option" and clicking on Purchases in the MacAppStore and redownloading the Lion installer (but don't install)
Follow these directions to make multiple "hold c" bootable DVD copies of the Lion installer.
http://eggfreckles.net/notes/burning-a-lion-boot-disc/
Test the disks out, you can see it's just like the 10.6.8 installer disk with Disk Utility and everything.
With a Lion DVD one can install Lion AND the Lion Recvoery Partition on a new or totally erased drive, like we are about to do.
When you clone Lion, it only clones the Lion OS X partition, not the Lion Recovery Partition. So by totally erasing the entire disk and installing Lion from the DVD can the Lion Rececovery Partition and Lion OS X partition be restored and your GPT repaired and your firmware flushed.
So once you got a Lion clone disconnect it, then c boot from the DVD and erase your ENTIRE Lion internal drive, this means you have to select the drive makers name on the left, HFS+ journaled of course.
Once that is competed, install Lion fresh, this will create both the Lion OX partition and the Lion Recovery Partition.
When that is finished, don't bother booting into the fresh Lion install, simply option boot off the Lion clone and reverse clone onto the Lion OS X partition, this will place back Lion, all your programs and files just like before.
Then you should be back to normal, your GTP is fixed, EFI is fixed (reboot twice) and you have everything except the Windows bootcamp partition.

Hal.dll is missing after first boot after installing Windows

I've used Boot Camp Assistant to resize my existing Macintosh HD (even though I left 700GB free space on the disk in Disk Utility during setup; it would only allow me to resize an existing disk). I then let it reboot and started XP setup fine. Chose the correct partition and formatted as NTFS (since it's larger than 32GB), went through copying all the files successfully, and after it automatically rebooted, I get this:
Windows could not start because the following file is missing or corrupt:
<Windows root>\system32\hal.dll.
Please re-install a copy of the above file.
I've been following the documentation which is pretty thin when it comes to the actual install. It gives the impression "everything just works" but in my case it doesn't. How do you actually install Windows on a Mac and have it be able to boot after the apparently-successful installation process?

It may be my fault because I did a full format, and when it took so long, I rebooted, deleted the partition, and recreated it and told it to do a quick format. The instructions say not to create or delete a partition "other than as noted" in the picture or else I could lose my system partition. I didn't lose that but my problems might have been another result of my doings.

Can't boot after installing updates

I am quite new apple and this is my first problem I have encountered.
I downloaded updates and now my computer wont boot. I have tried safeboot and it just freezes on the 'starting OSX bar'. I have inserted 'install disk 1' (which is OSX 10.4.6) and gone through disk utilities to repair permissions and the disk - then starting from the hard drive in safeboot and it still gets no further than the 'starting OSX bar'.
If I chosse to boot from the install disk will it take me to the 'erase and intall' option.
What should I do? If anyone can help I would be very grateful.
Thankyou

I guess you could skip the steps you have done already...
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. 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.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then 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, reboot when it completes.
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
May even need to do an Archive and Install if you have room on the HD...

[SOLVED] Can't boot after install

I installed Archlinux using the FTP LiveCD. Everything finished good, and there were no errors. I then reboot and Grub comes up like it's supposed to. But when I try to boot into Arch it says:
Booting 'Arch Linux'
root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/9e26f3d3-464b-4cca-9117-db1ff8v1a961 ro
Error 15: File not found
Press any key to continue...
I tried going into the Grub and changing the by-uuid to /dev/sdb1 (Which is where the root partition is) but I got the same thing.
My partition scheme is like so:
/dev/sda1 /home
/dev/sdb1 /
/dev/sdb2 swap
Any help would be greatly appreciated!!
Thanks!!

Thanks everyone for your help!!!!
Maybe this should be documented: It is quite common that the BIOS drive order is different when booting from CD than when booting from the hard drive. Also, grub often guesses the drive order wrong. The only way to be sure is to install grub to the MBR and analyze the drives from there.
Your problem might make more sense though: As you installed grub in the MBR of the second hard drive, you probably told the BIOS to boot from the second hard drive instead of the first. This causes most (all?) BIOSes to reorder the drives so that the second hard drive appears to be the first. And GRUB only accesses the hard drive through BIOS. Linux doesn't care though, it has its own order (which might change too) and we use UUIDs to identify the drives anyway.

Can't boot after installing 10.5.4 on 17" powerbook

I've has Macs since 1987 and have never seen this one. I bought a family pack of 10.5 and it installed perfectly on both my Intell Powerbook and my wife's EMac. yesterday I tried to install it on my mother-in-laws 17" power book. It seemed to be working fine even though I had to ignore some Norton warnings. Even managed to get on the internet. So I shut it off. After a couple of hours decided to try it again just to make sure everything was working before I sent it home with her. The chime sounded, the little propeller thing started turning but after quite a while I got a picture of a circle with a line through it. Kind of like those warning signs like no smoking or no whatever without any words. It stayed like that for 15 minutes until I finally shut it down. Tried to reboot using the Leopard install DVD holding the C key down and got the same thing. Got kind of panic cause my MIL hadn't backed up for awhile. Finally got it to reboot using the 10.3 install discs so decided to just install 10.3 and see if I could back up everything before trying again on 10.5. Two questions:
What is that symbol ie what does it mean? and
What do I do about it?
Thanks '

Normally this issue would only appear with Disk Doctor or Speed Disk on any version of Mac OS X. Since you are using anti-virus, then it probably was more likely due to something else that made the directory damaged. See my FAQ* on the directory:
http://www.macmaps.com/directoryfaq.html
Norton's anti-virus and firewall are actually relatively redundant except in cases where you are trying to avoid becoming a "typhoid mary." If using them, make sure the version they have has been tested with your operating system. ClamXAv is a much better anti-virus application for more current operating systems as it offers less bloat on the operating system.

How can I partition internal HDD after installing Windows 7 Professional via Boot Camp 4.0?

I recently purchased MacBook Pro 13" (Late 2011) model with OS X v10.7.2 Lion installed. I've upgraded to OS X v10.7.3 Lion and updated all other software.
I require Windows 7 for some Windows based softwares that do not support Mac OS X. Therefore, used Boot Camp 4.0 to install Windows 7 and then tried partitioning single internal HDD to have 3 partitions (4 total including BOOTCAMP partition). Disk Utility created a 648.5MB partition and then I was able to create 3 other partitions of custom sizes. After applying these changes, I got an error message that said selected volume size is too small. I resized this 648.5MB partion to a custom size and had total 4 partitions, including BOOTCAMP.
After reapplying these changes, BOOTCAMP partition was removed and I was left with only 3 partitions and empty space.
I've tried several different ways to partition the disk, all in vein. Is there a way I can partition my single internal HDD after installing Windows 7 Professional via Boot Camp 4.0?

You can't do what you want with GUI utilities, which will only allow a total of 4 partitions due to the limitation of MBR needed to support Windows. Those four partitions: EFI System (hidden), Mac OS, Recovery HD (hidden), Windows. So with Lion, you only get two visible partitions if you're going to use Windows with BootCamp. You can't make anymore with the included graphical tools.
If you need more partitions you'll need to use something like GPT fdisk (gdisk) to create the partitions in the GPT first. Then add the Windows partition only to the MBR and flag it as bootable. gdisk can be googled and downloaded for Mac OS X off sourceforge. It is not a GUI tool.

I can no longer boot up in osx after installing windows 7 with bootcamp

After installing windows 7 with boot camp I am no longer able to access my osx side, I do not receive an option when holding alt when turning on my MacBook

What options do you get? If you don't get any options then you may not be pressing and holding the option key long enough or you are pressing it too early or too late.

Windows 8.1 Pro will not boot after installing iTunes 11.1.5.5

It's a little hard for me to accept that this is true, but the symptoms seem to be pointing the direction of the title of this thread. I have an all-in-one touch-screen Gateway computer that came with windows 7 (yeah, a win7 machine that came with touch, yeesh) and I put windows 8.1 pro 64-bit on it with a clean install (actually windows 8 was the clean install and then I did the free microsoft store upgrade to 8.1). It has 4GB of RAM and has a Pentium Dual Core cpu @ 2.2 Ghz. It was running fine with the previous version of iTunes, but as soon as I updated to iTunes 11.1.5.5 (and there may have been other apple things that updated too (ie quicktime of course), the computer prompted me for a reboot and froze during the reboot process (before it even shut down). Then it had trouble booting into windows. I ran startup repair to no avail and decided to do a sytem restore. My most recent restore point was from a few weeks back, before iTunes was even installed at all on the machine. I went back to that point and the machine worked fine again. Then I installed iTunes 11.1.5.5 and the same exact problem occurred - it froze while shutting down after the iTunes install and then would not boot into windows 8. I did another system restore and have not put iTunes back on. The system is working fine. I'm going to try to find out if there's a way to download older versions of iTunes, so that I can install it, but the bigger issue here is: Is this a legitimate bug/incompatibility with some hardware or software or driver that I have on this computer? I run a computer support business so I know my way around but I don't have time to troubleshoot this from scratch. Anyone else seeing this? Apple employees...a little help here? Any input?

let it sit for about 30 min and still got nothing
I then did a "hard shutdown(just pressed power button till it turned off the computer)"
That may not have been long enough. But a "hard shutdown" would definitely have been construed as a problem due to the update.
Asus apparently is a known problem case...
