Black screen with cursor at boot


Whenever I have start Windows, after loading the Windows Logo, it stucks to a black screen with a mouse cursor. I am able to move the mouse, but is unable to do anything else. I tried booting in Safe Mode and all Recovery Options, and either, it's the same thing or a BSoD saying 'Unmountable_Boot_Voloume' appears. The next problem is the screen with the cursor is displayed even when I try to boot from a repair Win 7 disc.

Any help is appreciated. Thanks in advance!

Hi Jim,.

Thanks for posting your query on the Microsoft Community.

According to the description, I understand that you get a black screen with the mouse on your Windows 7 computer.

This could happen due to some system conflicts.

I suggest you to refer to the suggestions of the spirit MS MVP responded on May 8, 2010 and check if that helps.

    E7440 Dell with Windows 7 Pro


    E7440 has a ssd msata 250g installed with an msata to sata adapter. Hard drive's MBR mode. The system works well on Windows 7 pro. E7440 comes with an msata slot, so I removed the adaptor and connect directly on the slot msata ssd. Then the black screen with cursor problem happened. Put the adapter back with ssd and Windows 7 booted up normally.

    I made a disk image of the ssd adapter so that Windows 7 is running, then restore the image to a disk sata hard. The black screen problems are out again.

  • Windows 7 Pro black screen with cursor on all modes and no login screen

    OK so basically, it's how, my laptop decided to me-screw right when I need to make some adjustments to my final project for next week.

    Friday he started very well in class and at the end of the course at 6:30, I stopped him. I normally don't that often stopped because I usually find myself opening upward in an hour later. But I did this time and when I got home and turned on around 9:00, it started like this:

    Screen Compaq PhoenixBIOS > Windows boot animation > black screen with cursor mobile, no login screen

    No screen connection. No sound. Not nothing but a black screen and the cursor movement. So I force shutdown and turned it back, this time he asked a chkdsk and I ran it. A ton of stuff file unreadable came and it took all night to run through it all. Tried to start again and Windows Error Recovery came and I tried all Modes of security and start normally and all produce the same black screen and the cursor with no login screen.

    Then I used my Windows 7 dvd repair to try and system restore to a week before. That's where I noticed that windows had installed a critical update at 12:00 on Friday. Tried to restore before that, but he failed. Gave me an error 0 x 80070057 and said I should run chkdsk /r and then try again. Then I used the cmd prompt through dvd repair and he has seen all these things wrong file again once recovered things then realized hours later. Tried to restore the system again. Still the same error. A run chkdsk again through the cmd prompt, then he went to clean without errors or orphaned files or anything, but it took a lot of time. I used the Startup Repair, and he has not found anything wrong either. But still the same error the system restore.

    So I looked around online for the last two days, trying to figure out and that someone said to try CTRL + Alt + Delete, the sticky shift key thing. So I tried to boot the system again, same black screen with cursor movement. I did CTRL + Alt + Delete, nothing. Press and hold the SHIFT key, and a pop-up window asked FilterKeys. Press the SHIFT key 5 times, a popup asked about sticky keys. But that's all I can get it to do. Nothing else. I tried to boot into safe mode with F8, chose, each of them and that changes in screen resolution and the words "safe mode" in all the corners of the screen. If the repair dvd's while I start in safe mode, it will open as well in safe mode, but with the same black background mode. Tried running sfc/scannow through repair invites cmd of the dvd and it says a system repair is pending and he had to restart, and then run the sfc/scannow. Tried, but it doesn't do anything when I restart except go to Windows Error Recovery asking either start in any safe mode or normally. And then it's just black screen again.

    So I am at a complete loss what to do now. After all of this mess, it seems that this Windows Update Friday afternoon did something and when I booted it upward once again, his cause nothing but problems. I think it has something to do with the display and the graphics card drivers? It's as if the thing starts but I do not see anything either because the sticky keys appears, but sees nothing else, no matter what I do. Seriously, I don't want to this junk because this is a new hard drive and I was just able to retrieve my files from my old hard drive that had epic failures as well. And I just got this new specifications I wanted as well.

    Laptop Spec:

    Compaq CQ50-115nr
    OS: Windows 7 Professional
    HARD drive: Western Digital Scorpio Blue 320 GB SATA WD3200BEVT
    Processor: AMD Turion X 2 RM-70
    Graphics card: NVIDIA GeForce 8200 M G
    Memory: 3 GB RAM

    If someone could seriously help me I would be VERY happy.


    This isn't good news.


    STOP: 0XC000021A

    Can be a difficult problem to solve, and you indeed need a technical help in a real store of the computer
    (not the leeks and the glances at a BestBuy or other BigBox stores) or system manufacturer support.


    This error occurs when a subsystem of mode user, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), irremediably compromised and security can not be guaranteed. In response, the operating system goes into kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, it is one of the rare cases where the failure of a user mode service can stop the system.

    Incompatible system files can also cause this error. This can happen if you restored your hard disk from a backup. Some backup programs may skip restoring system files which they determine are in use.

    Solve the problem

    Run the kernel debugger is not useful in this situation because the error occurred in a user mode process.

    Resolve an error in the user-mode device driver or system, third-party application service: Because the bug 0xC000021A control occurs in a user mode process, the most common culprits are third-party applications. If the error occurred after the installation of the new or updated device driver or service system, third-party applications, the new software should be removed or disabled. Contact the manufacturer of the software on a possible update.

    If the error occurs during the system startup, restart your computer, and then press F8 to character-based menu that displays the choice of operating system. In the Windows Advanced Options menu that results, select the last known good Configuration option. This option is most effective when a pilot or a service is added at a time. If the error is not resolved, try to manually remove the offending software. If the system partition is formatted with the (FAT) file allocation table, use a MS-DOS boot disk to access the hard disk of the computer. If the system partition is formatted with the NTFS file system, you may be able to use Safe Mode to rename or remove the defective software. If the defective software is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console to access the file. If a room newly installed if material is suspected, remove it to see if that fixes the problem.

    Try running the emergency recovery disk (ERD) and allow the system to repair any errors that it detects.

    Solve a problem of file system do not match: If you have recently restored your hard disk from a backup, check if there is an updated version of the backup/restore program available from the manufacturer. Make sure that the latest Windows Service Pack is installed.

    It's my generic bluescreen convenience store - you can try Mode safe mode as suggested in article

    BCP2: 8C013D80
    BCP3: 00000000
    BCP4: 00000002

    or in this format:

    Tcpip.sys - address blocking 0 x 0 00000000 000000000 DateStamp 0 x 000000000

  • I have a black screen with cursor before logon for Windows 7, 32-bit. Help, please.

    Tried to start in safe mode & start the laptop very well, but once I went back to the startup by default, face the same problem again.


    Take a look at this thread and follow the same steps listed in the breast.

    In particular, the bit on a SFC/scannow. Sometimes when you unplug a PC like that, you can damage some essential Windows files. A SFC scan should be able to fix it.

    This link contains a lot of other really good as well troubleshooting procedures.

  • Start window manager: sometimes when I started my PC I have a black screen with the Windows boot manager at the top.

    Sometimes when I start my PC I have a black screen with the Windows boot manager at the top.  Although there are several options available, that nothing happens no matter what keys I hit and the only option is to shut down the computer and restart completely.  Sometimes the Boot Manager page turns and my office sometimes opens fine.  I've updated with everything Microsoft has Windows Vista and I still get this screen.  Anyone has any ideas.

    Do a startup repair and see if that fixes it:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    Link above shows what the process looks like and a manual, it load the repair options.

  • HP laptop: black screen with cursor

    When I turn on my computer and type my password, it goes to a black screen with a cursor.  I tried different things but nothing works.  I just did a restore of the system 2 days ago cause the fan was not working. It worked yesterday.


    Boot the computer normally and log.

    Black screen, hold down the ctrl and alt keys and press delete.

    Select Task Manager.

    At the bottom left, select details (if it is not already selected).

    Click in the header of column Nsoul to organize the processes in alphabetical order.

    Look for an entry called to run once Wrapper (RunOnce.exe) - If you see it listed, right-click on it and select end task.

    If your office now appears, download AdwCleaner on the following link (there are 4-5 second delay until it's available)- Save in your downloads folder.


    A once downloaded, close all programs, open your download folder and double-click the application to run it (click Yes to any uac prompt).

    Click the scan button.

    When the results are displayed, click the Clean button - when you are prompted to restart, click Ok.

    It starts on the desktop correctly now?

  • I have the virus of file recovery, now I have a black screen with cursor blinking in the upper left corner.

    I have a Pavilion Notebook and recently caught the virus from file recovery.  I bought and ran the disc of Trend Micro Titanium Maximum Security.  Now, I get a black screen with a flashing cursor in the upper left corner of the screen.  All tests ran for memory, hard disk, etc. are OK.  Now I have a recovery disk, but have not backed up my files.  Any suggestions?

    Download your backed up files, then you can boot from your recovery disks to reinstall Windows.Several options to do so.

    Remove the hard drive and attach it to one > USB adapter . Plug it into another computer via usb port and copy files off the power.

    You can use > Ubuntu Live CD to boot from and backup files.

  • Windows starts, but does not charge not (black screen with cursor)

    [Sorry for the long post, but I feel the need to explain my situation]

    I have the following problem:

    I turn on my PC, and Windows shows it is normal loading screen, then it goes in a completely black screen, with just the mouse in the middle. By the size of the cursor, I can say that it is in a low resolution, probably 800 x 600 (compared to my usual 1920 x 1080). I am able to movements of the mouse, but with no particular purpose without something to click on. No other keyboard input seems to work, except for press SHIFT 5 times, which shows the keys dialog box to self-retaining (with just 'yes' or 'No' options, no other connection); and Windows key + U, which shows the ease of access Center. CTR + Alt + Del does NOT work.

    So far, that's what I tried (in chronological order):

    1. Start in Safe Mode, Safe Mode with network, safe mode with command prompt Mode, start low resolution video, last known good configuration: all give the same result as to start normally.
    2. Repair of your computer:
      1. Startup Repair: find the registry errors (I realized and fixed this more later on)
      2. System Restore: did not find any previous restore points (I know with certainty that there is, I took the habit of making regular restore points).
      3. Windows memory diagnostic: not found error.
      4. Command prompt:
        1. Ran the command chkdsk /f r, has no error report.
        2. Ran sfc/scannow: I don't remember the exact report, but he asked to restart the computer to complete the repair of the problems. I rebooted and ran the new order for the same result.
        3. Forced the scan with: sfc/scannow damaged = c: \ /offwindir = c:\windows, concluded and repair errors, not always not load windows.
    3. Ran Dell Diagnostics start, found no errors.
    4. Startup Repair ran found once again the registry errors. I found the solution to this in a forum for Microsoft Help ( ) and fixed the problem. I rebooted, but the problem persists.
    5. Startup Repair does not detect now no error. I tried restoring the system again, we find 2 restore points dated AFTER the beginning of my problem. I decided to restore it in any case, but none of them worked.
    6. I ran Windows Defender in offline mode:
      1. Quick scan: and found 2 threats and remove.
      2. Full system scan: found 4 more threats, removed 2 of them, the other two could not be removed because they were in an ISO file.
    7. I've tried steps 1, 2 and 3 with no luck.

    With every step, I am aware that I am closer to having to reinstall Windows, then I decided to see if I could still access my HD to save my personal files. I did a live Linux CD (with Ubuntu), but I have a problem of mounting the readers, because they are in a RAID0 configuration. "sudo dmraid s" gives the following error: "ERROR: Sie: number of devices in RAID wrong value"isw_dbdffjficc_ARRAY0"[1/2] on/dev/sdb.

    Important details:

    I changed my graphics about 4 months ago (a 750ti of Nvidia GTX for an ATI Radeon HD 6450), and told me that I can run short with the power supply. The new card requires a minimum of 450W, and I think that my diet is 460W. This may or may not have something to do with this question, I have no idea.

    My 2 hard drives of 500 GB RAID0 configuration has brought me a lot of problems of the day 1. One of the HARD drive would be randomly (I am able to hear a clicking sound different when this happens) failure and the computer would break. At the start, he would ask a boot device. The Dell boot utility would then recognize only 1 readers, but would end without errors. After a reboot or two, everything would be fine and would be boot windows normally (apart from the usual error recovery screen) with no sign of corrupted data or anything. As I said, it happened are the arrival of my PC, but restarting a couple of times still attached. From now on, the two HD seems to work very well, the Dell utility recognizes two of them and found no errors in one of them, and I can access any directory from the command prompt.

    Is there anything else I should try before reinstalling Windows?

    Before the installation, I really wish I could recover my files (I have important documents of the College), is it possible to do this?

    Sorry again for the very long post (and for any errors of language, English is not my native language) and thanks in advance.

    Since you have not yet had your data readers. I recommend a Windows installation without formatting the drive... I don't like this solution, but at this point, you have probably tried everything.

    Use a reinstallation of Windows 7 installation DVD, make sure that you select...

    Select custom: Install Windows only (Advanced)

    If you do not select one of the route options and everything simply highlight the largest partition and click Next:

    Windows will dump all the old Setup files into the Windows.old folder

  • Black screen with cursor when connecting Windows 7. Reinstall the drivers doesn't help not.

    I have a Windows 7 Pro machine that boots to a black screen with a cursor instead of the login prompt, but if I press some keys like enter and tab that I will get a few blue squares where probably windows are appearing.

    I can boot into safe mode and log in. I can then disable or uninstall the video card and the boot into normal windows. But if I install the Intel to the HD3000 integrated video drivers, the black screen will be there waiting for me when I reboot.

    I tried with and without external monitors connected.

    I tried to uninstall the drivers in the menu programs and features (also selection to completely remove the drivers), and I uninstalled them through Device Manager. I then reboot before installing the Intel drivers again. I tried the version on the site Web of Panasonic, as well as the latest version of the Intel Web site. Results have been the same every time.

    Are there left behind somewhere that I could try to remove registry keys? Perhaps a more thorough removal method? Something more creative? All ideas welcome!

    Hi Brian,.

    According to the information that you, as you can start your computer in safe mode without problem, then the problem is probably with the supplied driver. Since the installation of the driver is causing the problem to occur, one possible cause is a driver you want to install is not compatible with the system. We suggest that you contact the manufacturer of your computer for help on installing the correct driver for your PC.
