Can't boot into Windows 8 Single Language 64 bit or access the BIOS screen with the F1 key
I have in my possession right now a Lenovo E49, Model name: 3464
I am unable to access the BIOS settings at POST by pressing the F1 key. Neither does it respond to the Enter key when it displays the message "To interrupt normal startup, Press Enter". I am also unable to boot into the installed OS Windows 8 Single Language 64 bit.
For your informtion, these are the events that led to this issue.
I accessed the BIOS settings at startup using the CHANGE PC SETTINGS option in the CHARMS menu in Windows 8 Single Languge 64 bit followed by GENERAL and ADVANCED STARTUP. Then I chose Restart Now. Windows restarted to produce the startup screen where I chose Troubleshoot, followed by Advanced Options and UEFI Firmware Settings, followed by Restart. This took me to the BIOS settings screen. Once there I changed the boot settings in BIOS so that SECURE BOOT was turnned OFF. It was in ON state prior to that. I also changed the BOOT MODE to LEGACY ONLY. I also changed the BOOT ORDER to boot from DVD drive first followed by the Hard Disk and USB Hard Disk. I saved the changes by pressing F10.
Now the computer is able to boot from the DVD Drive. I tested this by inserting a Windows 7 Repair DVD and also a Linux Live DVD. Mind you, I didn't mke any changes to the Hard Drive. I'm also able to boot from a USB Hard Disk. This too was tested by inserting a bootable USB HD that had both Windows 7 and Windows 8 OS installers. I used only the command prompt feature in the Repair option on the Windows 8 installer to ensure that I could access the partitions on the HD. I did not in any way install Windows 7 or 8 on the HD.
If there is no bootable DVD or USB HD inserted, the laptop is involved in a loop that restarts followed by a message that says the following:
"Intel Undi, PXE-2.1 (build 083)
Copyright (C) 1997-2000 Intel Corporation
This product is covered by one or more of the following patents:
US5, 307, 459, US5, 434, 872, US5, 732, 094, US6, 570, 884, US6, 115, 776 and US6, 327, 625
Realtek PCIe GBE Family Controller Series v2.41 (06/08/11)
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM."
I am positive that the current state of the BIOS is such that it does not accept any input keys like F1 and F12 at POST so that the BIOS can only be accessed through Change PC Settings in Windows 8 as I had done prior to the occurence of the issue. Since I cannot boot up Windows 8 I cannot use this method to access the BIOS. And since it is not possible at this stage to access the BIOS settings through the F1 key, I believe Lenovo must have surely provided another alternative to enter the BIOS. Can you kindly tell me what other way is there to do this. In earlier days, one could reset the BIOS by shorting the BIOS through pins on the motherboard. Is that possible now? Or is there some Lenovo BIOS utilily that enables me to change the BIOS setting to boot with Legacy and UEFI? Or do I have to install Windows 8.1 64 bit in Legacy mode?
I'll see if another member of the team can jump in here and offer more help...
What I might imagine is that you can only access BIOS from a cold boot. Windows 8/8.1 have hybrid shutdown and don't completely shut down the machine normally, so even when it powers off, it isn't fully off and the next boot is not really a cold boot.
Please see this KB. I realize this assumes you can get into windows.
As you suggest, it also seems as though you have set legacy vs UEFI and that may be why your drive is not currently booting. Can you remove the battery on your system? If not, is there a reset hole on the bottom? Removing battery and AC and pressing and holding the power button several times, then re-attach AC and Battery and try to restart and press F1 to get into BIOS. (Not familiar with models that use enter for BIOS).

Can only boot into Windows 7. Can't even boot from Snow Leopard DVD.
I have no idea what prompted this. I don't recall installing any OS updates recently, other than some Windows Live apps in Windows 7.
I have an early 2009 Mac Mini with Snow Leopard, and have Windows 7 64-bit installed in a Boot Camp partition. When I installed Windows 7, I couldn't get the Boot Camp utility to install within Windows (I guess because it's 64-bit) so to switch back and forth between OSes, I just shut down the Mac and restart it with the Option key pressed, and select Mac OS X when I want to return to Mac. This has worked for about a month and a half now (ever since I got Windows 7). Suddenly I have problems.
I first had problems booting into Windows or Mac. I got to the grey screen with the Apple logo, with that spinning "progress" thing going for a while, then it would freeze up and get stuck on the grey screen with the Apple logo. I zapped the PRAM. No help. Then, after disconnecting all external drives (I have several) and extra USB devices, I was able to boot from the DVD install disk and reinstall Snow Leopard on my internal drive. Joy, or so I thought. Then I booted into Windows 7, and after some weirdness getting it to start, it did successfully start and ran just peachy.
Then I turned off the Mac and held down the option key (as usual) to return to Mac OS. But now all that happens is that I get a grey screen for a few seconds, then the Mac boots back into Windows 7, which seems to work fine. (I'm in Windows 7 right now.) I turned on one my external drives (Snow Leopard installed, connected via Firewire 800) in hopes that the Mac would boot into that, but same thing. Ignored and back to Windows 7.
Then I thought I'd boot from the install DVD again by putting it in the drive and holding down the C key as I restart, but the same thing--a grey screen for a few seconds, and then booting right into Windows 7. I can't seem to escape Windows 7! It's a bit disturbing when it won't even recognize the install DVD.
I tried to call Apple Care since I'm within my 90 day support window, but of course they are closed. I'm figuring that I'm going to have to take this into an Apple Store, but thought I'd see if anyone has any ideas. Any advice will be appreciated. Thanks.According to Apple, Win 7 64bit is supported with Bootcamp 3.0. If bootcamp 3.0 is available; I could not find it anywhere on Apple's website. It appears the most recent version is 2.2. The only place I could find 3.0 is not on Apples website and it's a questionable source so I won't post it here.
It may just be a matter of time before Apple makes it available. I'm not suggesting you wait, however if the install disk can't be used, I'm not too sure where u could go from there. Calling Applecare might work.
If you do a simple google search using the terms 'download bootcamp drivers windows 7' u will see what I was referring too.
Here's what I found from Apple (It doesn't specifically mention 64bit however just win7): http://support.apple.com/kb/HT3920
This is not from Apple, but specifically addresses whether they support win7 64bit: http://www.macnn.com/articles/09/08/31/boot.camp.win.7.64.support/
Here is more info about bootcamp 3.0 and win7: http://www.apple.com/support/bootcamp/ -
Can't boot into Windows 8.1 partition after apple store repair
Can't boot into Windows 8.1 partition after apple store repair
I went to the apple store about a week ago to get my screen fixed, and when I get it back I don't have an option to boot into my windows partition. The bootcamp partition is still there, but I can't boot into it. I can still see all of the files on the drive. When I try to boot into windows from the startup disc setting I get "no bootable device — insert boot disk and press any key” on a black screen. I went in for a dead pixel, and the guy at the genius bar ran something on my computer and went into disk utility application. I’m not sure what he was doing, but obviously that’s what messed up my windows partition. How can I be able to boot back into windows? Here's what disk utility looks like on my computer.Here's the output

Hi, can anyone help with the problem I am having with pro book 4440s? I can't boot into windows 7, nor can I enter the bios cause i fogot the password. the error I am getting says "windows failed to start. a recenr hardware or software change might be the cause. it then gives me options to boot from a disc but I can't do that cause I am unable to get into the bios to change it to boot from a disc.
The error message goes on :
File: \Boot\BCD
Status: oxcoooooof
info: An error occurred while attempting to read the boot configuration.
the only two options on the screen are enter=continue and ECS=exit
I just can't get pass this screen.
Please help.
ThanksHi,
If you don't already have one, use another PC to create a Windows 7 Rescue CD. Download the relevant ISO from the links below.
Windows 7 32bit
Windows 7 64bit
You should use an application such as ImgBurn to burn the ISO to a CD - a guide on using ImgBurn to write an ISO to a disc is Here. Once created, or if you already have this, tap away at the esc key as you start the notebook to enter the Start-up Menu. Insert the Rescue CD. Select Boot options ( usually f9 ), use the arrow keys to select the CD/DVD drive and hit enter. You may also get a prompt to 'Press any key to continue' - do this if asked.
When loaded, select Repair Your Computer and choose the Command Prompt. When this loads, enter the following commands and hit enter after each one - include spaces as shown.
Bootrec.exe
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd
bootrec /fixmbr
bootrec /fixboot
Remove the Rescue CD and try rebooting the notebook.

Can't boot into windows 7 anymore......
Hi all, I have a Mac mini late 2012 with windows7 installed through bootcamp5. It has worked flawless until recently, now I can't boot into windows anymore. I've checked in finder and the bootcamp partition is present and also all the files. Before that, I did have some trouble with my LaCie 2big thunderbolt hdd, it kept on saying I had to reformat one of the discs in the drive, but only when used in windows, in OSX there was/are no problems reading the hdd .......
Any idea of how I can make windows bootable again?, do I really have to make a fresh install of windows to make it work??
Any help is very much appreciated
Kindly

My Macbook aliminium unibody from late 2008 will not boot. I reach the grey screen with the apple icon and the spinning grey gear. I used disk utility to boot it but it said integrity test failed. I don't know what to do can anyone please help?
Sounds like you may have a harddrive issue. You are probably going to need to get that changed out and then install the OS X again to get it going.

My iMac won't boot up fully. It stays stuck in the gray screen with the pinwheel spinning, then after about 5 minutes just shuts itself off.
Try SMC Reset (unplug it from the back of the computer for 10 seconds then plug it back. in)
Try PRAM Reset Cmd + OPtion + P + R on start up.
Try safe boot - hold down shift on start up.
Try booting to install dvd (C on start up) or recovery hd (CMD + R) and using disk utility to run a verify and repair. If you still can't boot after that reinstall the operating system. If you can't find the disc or it wont boot to the disc.
Try single mode which is cmd+S on start up. It will open with a terminal looking window in the terminal. type in /sbin/fsck -TL. If it returns *system has been modified* continue to type that command in until it comes back with macintosh hd seems to be ok. If after 5 tries it still gives you system has been modified. You may have to replace the hard drive. -
I have a macbook and when I power it on and then select myself as a user...It won't power up. It stays in the white screen with the apple logo. I am online currently under 'guest user'. Is there anything I can do from the keyboard to fix this??? Help!!!
Could you specify the model of MacBook and the OS X it's running, please? Some of the advice or references vary along with the system, so this could be helpful to formulate a reply. I've never used a Guest User selection, but do have more than one User.
If the computer does not have an optical drive, you may be able to boot it into a recovery disk mode or something; in an attempt to see what is wrong and maybe fix it.
Good luck & happy computing! -
My MacBook Air can't get past the gray screen with the apple logo. What's the fix?
My MacBook Air can't get past the gray screen with the Apple logo, so I can't login. Does anyone know the fix for this?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Before reconnecting an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, reboot as usual (i.e., not in safe mode.) If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see above for instructions.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it produces. Look for the line "Permissions repaired successfully" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
My mac doesnt start. All i get is the gray screen with the apple and the loading icon but nothing more happens. I tried to start it in safe mode but it doesnt help. What can i do?
If you have a external USB enclosure - trying installing your hard drive in that enclosure and connect it to your usb port - restart your macbook while holding down the options key. If you Macbook boots to your desktop then you have a faulty cable. If you get the same error, then your hard drive just died on you.
good luck. -
I downloaded ios7 on my iphone 5 yesterday. All day it worked fine, then last evening it started blinking from the white screen with the black apple to my home screen. Each screen only stays up for 3-5 seconds then switches back. I have tried shutting down and it is still happening! Does anyone know how to fix this issue without having to go into the store?
Your power adapter is OK. If the only place it will not work is in your home, your house wiring and / or the appliances connected to it are likely to be the reason your Mac will not charge.
From Troubleshooting MagSafe adapters:
Identify line noise issues.
Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.
If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter's "over voltage protection" feature senses ground noise and then turns off the adapter.
Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.
Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.
Household wiring problems are very common. They can also be very dangerous. Fortunately most problems can be easily fixed by a qualified electrician. -
