Can't boot to windows, stuck at black screen (with cursor)

Hi! I'll get straight to my problem: I can't boot to Windows (Windows 10 Technical Preview) anymore after installing VirtualBox (or rather, an Android emulator that installed VirtualBox) on my system. I get stuck, after the loading animation with the blue HP logo, on a black screen (I can move my cursor around) but the login screen never shows up.
The problem.
I'm currently dual-booting linux and windows for several purposes. My laptop came with a Windows 8.1 OS by default. Some time after the Windows 10 Tech Preview came out to public, I upgraded my system to Windows 10 (so my 8.1 is gone now). Everything's going well until I installed this Android emulator (which installed VirtualBox) on Windows 10. Everything seemed fine at first but after rebooting, Windows isn't working anymore. I can still boot to linux, but Windows just won't boot properly.
What I've tried.
I've tried A LOT of things. The problem actually happened twice already (at first I was able to fix it with System Restore but not this time around). I have a Windows 8 USB Recovery Drive at hand, just so I can access a Windows command line. It's not from my system, though. It came with a new windows 8 laptop of a friend so I just borrowed it.
1: System Restore. This worked the first time. But now the restore won't finish and throws an error, telling me that it can't restore my system.
2: Refresh PC. "There was a problem refreshing your PC. No changes were made." or something like that.
3: chkdsk on C:\. It says it changed some files, but it doesn't really fix the problem.
4: sfc /scannow. Again, something happened, but it didn't get fixed.
5: bootrec.exe to fix BCD and MBR. Doesn't work. (as far as I know my sytem is using GPT)
6: Hard reset (remove all power sources then hold power button). Still not working.
7: System Restore again. All the restore points aren't working. It reaches a "Finished" state, but then an error comes up after. It says can't extract a specific file, and the restore point is damaged or might have been deleted during restore.
8: checking and fixing bad sectors (nope, no bad sectors on my hard drive)
9: built-in component tests. It passed all of them, except the battery test (my battery really isn't surviving for any duration longer than 30 minutes, but that shouldn't affect my OS). I didn't try the really long tests since I thought it wouldn't matter as my problem is most probably completely software (since linux is still working).
10: cry. oh please. Windows isn't working. What should I do? (
Things I haven't tried.
1: RAM and CMOS battery reset.
2: Reset PC.
3: Format hard drive.
4: Test hard drive on another laptop's system.
If possible I'd like to avoid getting my hard drive wiped, since I have a lot of stuff to backup (more than 300 GB of files + dozens of linux apps and ppas), and I only have a 32GB USB drive to backup all the files I need).
Thanks for reading.

Sorry for the delay. Wasn't expecting the "road work" signs when attempting to check back with you in the AM here.
As others have already mentioned, the prompt for file systems occurs during text mode setup. Quick or Full? FAT or NTFS? How do you know what to do?
We'll start with file systems, short and sweet. Most any OS can read and write FAT volumes without fail which makes FAT ultra-portable, and the only choice if you want to let Mac OS write documents on your Windows volume. It's also more efficient on drives of 16 GB or less. However, FAT has no folder-level access control, so any file in the system can be manipulated by any user or by any system process. By contrast, NTFS is far more restrictive. It can only be manipulated under Windows, though other systems may be able to read it. Not only do you get the access control that FAT lacks, but you also get superior efficiency on large volumes, plus the power to compress or encrypt folders and files at will (in "business" flavors of Windows only--and yes, Vista Ultimate counts as "business" even though it will be supported much like a "consumer" version).
On format speeds: A quick format is very handy if you have a large partition or a single drive completely dedicated to Windows. Because it completes in 30 seconds or less, it will go a long way toward completing your Windows install. However, in some cases, volumes formatted with a quick format may have reliability issues. They must have fixed this in Vista, because Vista can only format at the "quick" speed.
A full format tests all blocks of a given volume (as opposed to testing an entire disk unless the volume itself is the entire disk) as the file system structure is laid down. Bad blocks are marked as "used" when they are found. This type of format takes much longer as a result of all the testing, but the result is a more stable volume from the start.
Get past the formatting stage, and you'll be right as rain.

Changed my iMac but Can't Boot from Windows

I'm using iMac 21.5 with Mac OS X 10.6.6
All programs are updated.
I used to have iMac 24, but i removed it's hard drive and installed it on a new iMac 21.5
i can't boot from windows 7.
what should i do ?

Can you boot into safe mode ..... because if you can you can also reach "repair computer"! so reboot your windows partition, as soon as the bios appears start pressing F8 until you see "Advanced Boot Options" when you get there choose, "Repair your Computer" (1st selection on the page) and go to "Startup Repair" .. selecting that will cause Windows to attempt to repair the boot sector of it's partition, if it succeeds you'll be able to boot, if not no data will have been lost.
However please understand that without a backup of your windows partition data loss is a possibility under these circumstances. Windows hard drives almost never boot when moved from one installation to another. Read that last bit twice.
Good luck

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
Jan

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

Parallels VM - windows vm as guest os - so can install actually on Windows vm (vista)

I bought Dw cs6 standalone for windows and installed on a desktop once... ?This means I can install and in a laptop? this laptop may be a Mac running Parallels VM - windows vm as guest os - so can install actually on Windows vm (vista)???

Generally with Adobe software you can install and run it on up to two systems - including virtual machines - provided they are not used at the same time.
To move your license, it's also fairly straightforward to transfer the software between computers, if that's what you ever want or need to do.

Hi, can anyone help with the problem I am having with pro book 4440s? I can't boot into windows 7.

Hi,
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.

How do I find out whether my computer can be upgraded to windows 10?

I have been searching the HP web site to see if my computer can be upgraded to windows 10. I also tried the the hp support assistant and it just directed me to a sales page about windows 10. I don't want to mess up this computer and reload all the software if it is not compatable. Is there a list of compatable HP computers or an app I can run to check? I have wasted lots of time searching HP support for this information. Microsoft says to go to the manufacturer for this information. Please help.

They are in process of making that webpage to check, you can keep checking, the link on the page below is still broken. http://support.hp.com/us-en/product/HP-ENVY-Phoenix-810-400-Desktop-PC-series/7477706/model/7485498/document/c04758308/

Can't boot into Windows??

Hi!! This is my theory about not being able to boot into windows. If you have made a system repair disc like you should have made on day one; and your PC will not boot with the system repair CD, you probably have some serious hardware problems.
I'm going to steal this reply from cee64 again. A system repair CD can be made from any PC that is running W7 ect.
Hi I'm going to steal this reply from cee64. I'm sure he won't mind!
"It is quite possibly the hard drive is failing or has failed. The reason you can't get into the bios or boot from a CD/DVD is because the bios it hanging trying to recognize the hard drive. Try removing the hard drive and see if it will allow you into the bios or boot to a CD/DVD. If it does, go the hard drive manufacturer's support site, downlod their hard drive diagnostic ISO image, then use the burn from image option to create the self booting cd, then boot to it and run the most exhaustive diagnosis on it if it will boot. If you can't get it to boot to the diagnostic disk while the hard drive is installed you'll more than likely need to replace the hard drive.
If it won't get you into the bios or boot to a CD/DVD with the hard drive out of the system you need to try reseating the ram. If that doesn't help you probably have a bad motherboard. In this case it would more than likely be cheaper to just replace the laptop than fix it."
http://www.dummies.com/how-to/content/how-to-use-a-system-repair-disc-to-restore-windows.html
If Seatools found your HD good, then you have a good chance of using the recovery disks or the recovery partion to restore you back to factory setting. If that fails, you may be down to a bad motherboard. I know of no program to test the MB. You can use memtest 86 to test your Ram. I think it tests some parts of your MB, but can't say that for sure.

Hi! I stole this reply from Jerry Edited One link, because it failed to open
Let's start here. The spec above says your machine came with 32-bit Windows Vista. Have you changed it?
We need to reach the recovery environment. Can you do it this way?

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/

I can't boot to Windows after resizing my Mac partition.

So, I recently decided to resize my bootcamp Win7 partition. This is something I have done successfully before, by:
1) Booting into Macintosh
2) Using Disk Utility to decrease the size of the Mac partition (20GB the first time)
3) Booting into Windows
4) Using Mini-Tool Partition Wizard (third-party) to allocate the free space to the Bootcamp partition.
There were a couple issues caused by this the first time around, mainly the fact that Macintosh didn’t recognize the fact that the free space had been taken, and had trouble reading from the Windows partition. However, I could live with that. I have since rebooted to both Mac and Windows several times without problem.
Recently, I decided I needed a bit more space, and so started to follow the above steps, shrinking the Mac partition an additional 15GB. Only when I went to reboot to reallocate the space, the Windows partition didn’t show up as a bootable option. Confused, I booted back to Mac, and the Bootcamp partition was still there, but renamed “disk0s4”, and unmounted. Reparing the disk failed (“Invalid BS_jmpBoot in boot block: 15921e”). The disk wouldn’t mount (not even sure if it was supposed to be mounted earlier, but that’s what it looks like). It also appears grayed-out in the list of drives to the left. It looks like I can create a dmg from the windows drive, although I haven’t done that yet (I will soon).
Any solutions for this? Although I will erase the drive if absolutely necessary, it would be preferred if that wasn’t the first option to try. I had no problems like this the first time I resized the disk.
(My mac partition is running Mavericks, if that is of any relevance)

Kernel Panic, but I can still boot into windows? :(

Hi folks,
2007?'ish MBP 2.2
machine (normally) boots right in to SL (latest rev).
holding option, I can choose SL or Windows XP.
I have a firmware password set up (i know the password if i need it)
the problem: when i turn my mac on, it will not boot into Mac right away. I get an error that it's "unable to find driver for this platform: \ "ACPI\".\n"@/SourceCache/xnu/xnu-1486.2.11/iokit/Kernel/IOPlatformExpert.cpp.:1 389
there's more, but I won't type it just yet b/c I just thought of a possible reason:
I was reviewing photos with a client for a slideshow (everything is backed up..no worries) and she had a thumb drive with more photos. I plugged it in the USB, but it wouldn't read or open in finder.
No worries - I ran downstairs to my mac pro, it worked. Dragged the pics off.
Shut down my macbook pro b/c I wasn't using it and when I tried to turn it on later, this problem is there.
What I've tried:
resetting SMC
resetting PRAM
can't do the TDM - read the article about needing to install the software to open passwords, but hard to do if the computer is down (unless they mean installing it on the machine from which I'm trying to access it?)
i tried holding option to key in my firmware password, but the same thing happens - can't access the Mac side of things. I can access the Windows section and as I'm typing this, it looks like I'm able to access the install disc
Just thought I would post this for 2 reasons:
1. to see if there's anything else I can do (I am going to try disk utilities to repair the disc)
and 2. to help anyone else out in case they have the same issue.
Cheers,
Keebler

Backup what you can, boot from a compatible installer DVD, erase the hard drive, then reinstall OS X.
Alternatively, you can try the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

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).

MSI GE620 can't boot to windows after installing CoreCenter 2.0.6.8

I have made a very huge mistake by installing an overclocking software without knowing anything about overclocking :(
Here is what I have done
- I installed CoreCenter version 2.0.6.8, after the installation finished it ask me to reboot the system, so I reboot.
- First my system won't shutdown it tell be that S-Bar (an toolbar that come with my GE 620 laptop) prevent me from shutdown, so I hit force shutdown. Then the system started to shutdown but it stuck at windows logo (Shutting down screen) so I hold down the power button to force turn off
- Windows gives me an option to boot into safe mode (because I hold down the power button and it is unexpected shutdown), I hit start Windows normally
- It goes into a Windows logo screen like normal, but it won't boot. It's just stuck at the Windows logo screen. At this time I tell myself "OMG what I have done!???"
- I try most option in a boot option (not sure what it called, it's a menu brings up when you press F8). I tried boot into safe mode, safe mode with cmd (both stuck at loading disk.sys), repair system, enable low res (640x480), last known good config, Directory service restore mode and debugging mode. None of them are able to boot.
- I grab a Windows 7 Ultimate repair disc that I have created long time ago. And.... "Oh no! It even cannot boot into a repair disc!"
- I give a Hiren's BootCD 15.2 a try. I boot Mini XP from that disc and..... It can't even boot XP from the CD.
- Ok Ok, maybe it mess something with BIOS setting, I press DEL into a BIOS setting (I believed) and hit restore all setting to default. Unfortunately, my system still won't boot.
Any idea of how I can uninstall this CoreCenter or any clues that what it have done to my system?
The only thing I know for now is just re-installing Windows, but I need to backup some data in C:/ first. I think I can install windows without formatting and backup some data and re-install it with format.
My system information
MSI GE620 laptop (All of hardware is stock, I didn't change anything. Just install extra 4 GB of RAM)
CPU: Core i7 2630QM
GPU: nVidia GeForce GT 540M / 1 GB DDR3
RAM: 8 GB
OS: Windows 7 Ultimate x64
Update: I can't even boot from a Windows 7 installation disc!! *cry*

Having not yet installed Developer 6 on my own system, (still running most recent 200 version), I can't be exactly sure. However your problem sounds a lot like the problem I encountered in trying to get my Dev 2000 install to connect.
Here are some things to check:
Is your listener running?
Is your listener properly configured to look for your host machine?
Look in the Oracle Net 8 Assitant utility and see how many listeners have been established. This is where my problem existed. I had 2 listeners. One was trying to connect to my loop back address (127.0.0.1) and could not. The other was properly configured for my host address but would not run because of the failure of the other. Once I removed the listener the was using the loop back address things began to work.
Make sure you have the appropriate alias set up through SQL Net Easy Config and/or Net8 Config.
Thats all I can think of for now.
Hope something I said will help.
