Windows 7 Won't Start Up from Boot Camp

I got a new 21.5" iMac and set up a boot camp partition for a Windows 7 64-bit installation. It worked. I installed the latest boot camp drivers into the Windows 7, which was wonderful because it fixed the display to match my iMac's specs. Then I installed the latest Parallels 5 and had it recognize that Windows 7 system, and have been using it without problem. But I tried this evening to use boot camp to start up the Windows 7 system by itself and although I got a choice of Mac OS or Windows via the option-startup process, and selected the Windows startup, Windows 7 won't start up that way. I just get a black screen with a blinking white horizontal line in the upper-left corner. I keep waiting but it never gets past this. Tried turning it off and starting again, still no luck. Booted back into Mac side and Parallels VM of the installation still works.
Any help appreciated. I should still be able to boot into Windows 7 straight using boot camp, no?

I should add that I just installed 8GB of RAM to the 4GB the iMac came with. Possibly now that the total machine has a 12GB of RAM the Windows 7 system is confused and can't start up?

Windows won't start up under Boot Camp

I just made a Windows partition with the Boot Camp assistant utility and keep trying to install XP Home Edition with SP 2, but it keeps stopping at the point where it says "Starting Windows" and then tells me there's some kind of problem, check for "new hardware," or disable something or another I've never heard of, etc. etc. and try again. Same thing over and over. I have iMac, all the latest software, Leopard, etc.
Any ideas?
Thanks

Actually I emailed Bobby T. (his comments are a few postings below on his experience), and he suggested unplugging my printer and external hard drive (everything except for the keyboard and mouse) and starting over. That did the trick and it all went smoothly from there. The error message was a mile long and I can't recount it exactly. Basically it said Windows installation was abandoned, check new hardware and software for problems, etc. I suspect something about there being an external hard drive connected threw off the process.
As an aside, I really feel like Safari in Leopard is sluggish. Due to other problems, I pulled Leopard off my PowerPC G5 and put back Tiger, and that helped. Safari is still running under Leopard on my Intel iMac, and still seems sluggish. But, you know what's screaming fast? Explorer in XP running on the iMac. Holy cow! It's way faster than both of the other configurations. Faster than Explorer on my PC at work too. No idea why, but XP on the Mac is really responsive.

I can't start windows 7 normally from Boot Camp

I can't start windows 7 normally from Boot Camp.
It was running fine since I have installed it 7 months ago, but now it can't start or (restart) normally (safe mode is ok). It displays a black screen after showing the logo, and I have to shut down the machine. My Mac system is working fine. Mac technician (Genius Bar) has run a surface scan to verify hd integrity and proofed ok, but could not give any advice on Windows issues.
Please advice if anything I should do before cleaning up my partition and reinstall Windows.

I would guess and sorry for asking but you already tried booting from Windows 7 DVD and doing auto repair?
There are dozens of things to look at and do, and begin with chkdsk in Windows, yes but that only looks at one aspect. You can't really check for bad sectors on a drive's sectors. The best? to use the drive vendor's own utility actually, often with a linux boot CD or Windows program (they don't make Mac OS versions, one reason I first installed Vista over 5 yrs ago)
Restore check points
Uninstall last update or driver
Clean the system of debris temp files, caches, registry errors, fonts and left overs
make sure you have 20% and 12GB free space or more
A hard shutdown can create more problems.

plz help me

Hi Jaimie,
To install Windows via Boot Camp you will need to have a copy of Windows on a physical dvd disc.
If your purchase provides you with an ".ISO" file then you can simply burn this to a DVD and then follow the standard Boot Camp installation instructions.
Boot Camp instructions: http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.7.pdf
If you get stuck, just let me know the website you purchased Windows 7 from and I might be able to help you out.
Cheers

HT4407 Is there any way to download these files manually from another source? The download from boot camp keeps stopping at around 25% and then produces the error "Can't download Windows Support Software because of a network problem". Thx!

I am trying to install windows 8 at my macbook air boot camp

I am trying to install windows 8 at my macbook air boot camp but Boot Camp Assistant i showing an error that the disk cannot be portioned because some files cannot be moved. Back up the disc and use disk utility to format it was a single Mac OS Extended (journaled) volume. Restore your information to the disk and try using Boot Camp Assistant Again.
I had already installed teh first time Windows on my MacBook Air and Mac Book Pro. Actually I had more issues to install on the pro than Air.
But my Macbook Air had an issue on November 2013, 3 weeks after buying it and Apple gave me a new MacBook Air but they only transferred the information on my mac and the windows partion was lost according to them, they could copy it in to my new MacBook Air. Now that I am trying to install my windows I can not access to the aprtion section and get the error message from above.
What can I do to to install it? I am using a 32GB USB and OEM Windows 8 at USB External Drive. The same I used before. I dont know understand what changed if I did it before?
Please advise..

I think there's some remmants left over from when Apple transferred stuff over. We can try a quick fix, but if that doesn't work, I think the only option is to clean install OSX and then install Windows.
open disk utility, confirm that you only have 1 partition (mac journaled)
restart and PRAM reset
open disk utility and repair permissions twice
restart boot camp assistant
Does it work?
If not, I would boot holding command+R, choose disk utility from the menu and completely erase your HD (formatting it as mac journaled again). Then, install OSX on this HD. Once OSX is installed, don't copy your files over from the backup yet. Instead, start boot camp assistant and see if you can get Windows installed. You can copy back your other files after we get Windows installed.

Messed up Windows 8.1 install after using Boot Camp 4 drivers

Hey guys, I just finished successfully installing Windows 8.1 on my Mac with Lion. There were no issues there, but I royally screwed up the Windows partition after trying to install the Boot Camp support software from a USB flash drive. I didn't look into it enough and am now realizing (after the fact of course) that I needed Boot Camp 5.1 for support for Windows 8.1!
I realized that something was wrong when I tried to install the drivers and software from my Boot Camp 4.0.4 and I received a prompt on Windows telling me that it expected Windows 7 instead and then asked me to run in compatibility mode to see if that works. I stupidly clicked yes and then my Windows locked the screen on me. So of course, I unlocked it and the display is all messed up with my battery indicator at the top left, most of the screen is black and a small portion on the right side is not black. It instantly locks itself again. I can only repeat the process with no way to correct it (that I know of).
Is this install of Windows 8.1 salvageable? I am getting the new drivers from Boot Camp 5.1 now, but it won't help if I can't even get to the desktop for Windows. Help!

Right - this would be the easiest thing to do. Will I have issues the Windows license being activated again? I have actually never had to reinstall before so I have never had license issues.

Install Windows 7 Ultimate 64-bit via Boot Camp

I am using a 17" MacBook Pro with and Intel i7 2.66 GHz processor, 8GB 1067 MHz RAM and a 7200RPM 500GB hard drive. I am trying to install Windows 7 Ultimate 64-bit via Boot Camp. I do what Boot Camp tells me to do, but when my MacBook Pro restarts to boot from the Windows 7 disc, all I get get is a white screen! I have tried to boot manually from the Windows 7 disc, but it won't boot. It freezes on the white screen and I have to reboot the Mac using the Mac OS X partition. How can I fix this ASAP so I can install Windows 7? I need to get it done TONIGHT! I just found out that I am running the 3.0.2 version of boot camp on my Mac OS X 10.6.4 version. Is this the problem? Do I need to update my Boot Camp Utility? If so, how do I do it or do I have to install Windows Vista first since the update is a .exe file?

All of these discs came with my previous PC computers that I used to have, but I no longer have those PCs. Only their discs. Is using discs that came with other computers for those computers the problem? Do I have to use a Windows disc that has not been used before?

The disks that come with PCs most often include only the drivers and applications required by the PC they were made for. You can not use these disks to install on other than the original hardware.

"Booting from Boot Camp Assistant created USB Drive...Failed to load BOOTMGR"

Hi Apple Ppl of the Wrld: I need help I been working on installing windows 8 on my Mac.
Spec of equipment:
Mac Book Pro Mid 2012
Bootcamp Version: Version 5.0.4 (473)
Bootable USB Flash Drive: Type Scan disk 4 GB windows 8 pro iso image but without the driver and the 2nd Scan disk USB flash drive with 32 GB with the Bootcamp Drivers downloaded and saved to this drive.
Please Note: I also have the original back up installation disc for Microsoft 8 Prof 64 from Microsoft where I purchased it from.
1st Bootcamp is not recognizing the Original Microsoft 8 Pro backup disk from microsoft itself.
Solution: I created the New Image from the Original Microsoft installed disc in my desk top and changed the extension to .ISO then burned the ISO image into the newly purchased DVD+R. Then I ran Bootcamp Once again and it get the following error message "The installer disc could not be found -- Insert your Windows installer disc and wait a few seconds for the disc to be recognized. Solution
2: Created a bootable usb drive with bootcamp assistant successfully with bootcamp. Yes I close, ejected or un-mounted any image that was open or had been previously used then i restarted the Mac. Next, I start the bootcamp assistant tool once again then i get the same insert your windows installer disc message.
3: Then I try to resolve the installer disc not found issue: this are the steps i took: a). Lauch disc utilities
    1. Selected the top most drive 750 GB Macintosh HDD
    2. On the right you’ll see 5 tab buttons: First Aid | Erase | Partition | RAID | Restore.
    3. Choose Partition. Then I clicked + to add another partition size of the partition was 222 GB
    4. Change the Name of the Partition to BOOTCAMP
    5. Change the Format to MS-DOS (FAT)
    6. Click Apply to save the changes and then reboot your Mac and we’ll begin Windows installation.
    7. During reboot, press and hold the alt/Option key and you’ll be presented with drives to boot from.
    8. Use the arrow keys and return button to select the Windows yellow USB key drive containing your Windows 8 installation files.
    9. This will begin the Windows install. --> then i get the following message: "Booting from Boot Camp Assistant created USB Drive...Failed to load BOOTMGR".
4: Take the Mac to best buy and let them resolve the issue and charge me like a million dollars for it :'( since i have no other idea who to get this bootcamp working at all. This has been a terribly lengthy issue and it is not as simple as it is claimed to be since i started with the Original Windows Disc Purchased from Microsoft and I have the Optical disc drive which it should be simpler from what I understand.
Please can you help It would be of great help.
<Email Edited by Host>

from what i understand you are trying to install win 8 pro from a "backup disk" the one that you purchased from microsoft.
this will not work, it is not an installer disk.
you need to start the process again. erase the partition you made on your hdd. in disc utility click the minus button after selecting the bootcamp partition, then manually drag the divider down fully then apply.
next, erase your usb then format it.
download win 8 iso from here;
http://getintopc.com/softwares/operating-systems/download-windows-8-pro/
it is perfectly legal to use your purchased product key in this install.
in bootcamp select the iso image you just downloaded, select your preferred partition size, check all 3 options.
you have the support software on another usb but you wont need it so it can be discarded. the install will work far better with the iso and support on the same drive.

Boot Camp For Lion -- USB ISO Method --"Booting from Boot Camp Assistant created USB Drive...Failed to load BOOTMGR"

Hello, has anyone had experience with dealing with this speciifc problem?
In short, upon rebooting, I am getting a black screen with a line of text that says, "Booting from Boot Camp Assistant created USB Drive...Failed to load BOOTMGR." Nothing happens after that.
I am using Mac OS X Lion 10.7.4. I have an ISO of Windows 7 Prof. along with an 8GB usb drive. I changed the coding in my bootcamp program to allow for the normally first invisible option that allows creation of a USB Installation program using an ISO that is normally only for computers without an optical drive.
I have that box checked, the check for new software box, and the install windows box checked. I went through the process of creating the USB, downloading the software, and partitioning the drive. Then on restart, I get the failed to load bootmgr error.
Some people have suggested using two usb drives for this. I am trying that method but it does not seem to help thus far.
Can anyone offer any help?
Thanks.

HT5639 When I start up in Boot Camp it says that updates weren't properly installed and the system is reloading. It then automatically restarts in Mountain Lion. What is wrong?

I am currently using Windows 8 and also have Microsoft office installed but those are the only thing on my partitioned space. I don't know if I installed 32 or 64 version of Windows 8. Could that be the problem?

Can you deal with XP not being supported by Apple and Microsoft? no security etc?
Can you use Windows in a VM instead of natively?
All the drives other than the one with XP will need to be pulled.
Always have backups of your system, clone that you can boot from.
Boot Camp 3.0 was the last supported. You don't need OEM 10.4.6 DVD and your system with EFI and SMC updates (Aug/Sept 2007) may not like it.
32-bit version of Windows on EFI-32 will only get 1.9GB RAM.
Installing 64-bit Windows 7 is a bit harder. Vista pre-SP1 64-bit was the best match for install on my 1,1 and that was 2006-2007.
The new owner needs to deal with this, not you. And really they are better off with a $400 PC instead. Or use a VM.
the owner should put in a new SSD for the system and $44 buys 4 x 2GB RAM. Together it will run just fine. 500GB SSD now $250 / $135 250GB. Biggest issue is a video card on these.
The grey screen - you upgraded the graphic card perhaps.
Unplug everything. Hit power for 5-10 seconds. Reconnect cables for mouse/kb and power, and monitor. You just reset SMC. Yes there is a small button - pull drive #4 and any controller in top slot #4 to see the SMC motherboard reset button but you don't need to.
Any PCIe cards can also play a role and factor into XP or Windows not working.

Windows won't start after downloading driver.

I recently installed an audio driver for my Lenovo Ideatab Lynx but after restarting the device, windows won't start up. It shows the lock screen but after unlocking, the screen stays blank and wont show the start menu. I think i accidentally installed the driver from the windows 8 page when i do have windows 8.1 on my device. Is this why this is happening and how can I fix it?

Satellite P205-S6307
The only way it will start is in safe mode.
So you know how to get to the Advanced Boot Options menu using F8. Go there and choose Repair Your Computer.
When you reach the System Recovery Options menu, choose Startup Repair.
I've tried several things..
If that doesn't fix the normal boot, tell us what you've already tried. There's no point in our repeating all those.
