• I only see a black screen with cursor flashing in Windows 10 Boot Camp

  Why Boot Camp is so hard!

  I just reinstall Boot Camp for the second time on my MacBook Pro mid-2012 after I came across this problem the first time. Everything goes through until the drivers install and I restart my Mac after updates, that to have the screen go black.

  Why can I not just have a clean install * sigh *.

  Anyway, I contacted both Apple and Microsoft technical support, but they could not solve my problem. I know that other people seem to have this problem, but I have not seen a coherent solution for it.

  Any suggestion would be great!

  If the screen is black, try to disconnect your power adapter and check if the screen lets connect you. The default brightness may be too low. There are two distinct settings, battery and AC adapter.

  If the problem is related to the drivers, remove the current installation and re-install W10. On the first screen where you select the Bootcamp partition, physically disconnect the network connections and do not connect until Windows is completely installed, you have created an account and bootcamp drivers are fully installed. Once you test, create a Windows system restore point and disable the GPU driver updates.

  See also present on how to control the driver for the specific hardware updates.

• Black screen with cursor

  Problem:

  Windows startup but stuck on the black screen with cursor

  System:

  E7440 Dell with Windows 7 Pro

  Description:

  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.

  Safe mode works normally. Low screen resolution does not solve the problem.

  I also tried to copy of ssd hard disk drive, but Windows boot had another problem: session3_initialization_failed.

  Any help is appreciated.

• 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.

  Hello

  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.

  Cause

  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
  above - repeatedly press F8 that you start. Disks of Vista are probably necessary - if you do not try to repair it, you can borrow a friends because they are not protected against copying. You can also buy the physical disks

  required). You can also repair disks on another computer.

  Here are a few ways to possibly fix the blue screen issue. If you could give the blue screen
  info that would help. Such as ITC and 4 others entered at the bottom left. And all others
  error information such as codes of STOP and info like IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

  As examples:

  BCCode: 116
  BCP1: 87BC9510
  BCP2: 8C013D80
  BCP3: 00000000
  BCP4: 00000002

  or in this format:

  Stop: 0 x 00000000 (oxoooooooo oxoooooooo oxoooooooo oxooooooooo)
  Tcpip.sys - address blocking 0 x 0 00000000 000000000 DateStamp 0 x 000000000

• 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.

  OR ->Kaspersky CD has the ability to back up files.

  You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel - device
  Manager - graphics card - Double click on - driver tab - click on UPDATE driver - then right click
  on devices and UNINSTALL - REBOOT.

  Another method to try to get to the desktop (try in normal Windows Mode without failure)
  CTRL + ALT + DELETE and on the tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - then

  Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
  That there is no information on a black screen as it is on a blue screen just adds to the
  Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a
  Google to see the proposed repairs, whom some have worked however these cover a wide
  field efforts.

  My Dell Inspiron has recently crashed after installing the last "update automatically", and I had to do a full install of Win 7 OS from a disk Dell provided. I had to go as far as deleting all partitions to get the Win 7 OS to install. Once which was completed, I then tried to do a full system restore using my NTI Backup Now EZ 320 on a Toshiba Canvio 2.0. When he is finished with the restoration, I disconnected the HD and restarted my system... as stated. The system has rebooted and returned to the top with a black screen with a blinking cursor.

  Today, instead of start normally, my Dell displays the usual POST screen, then a black screen with a cursor blinking (dash). He is not following the XP splash screen. After the machine is turned off and restarting, I pressed F2 repeatedly and eventually got to the configuration of the system. Then I pressed ESC and exit, and the machine starts normally on the desktop. This has happened 3 times since. Social site from Microsoft suggests that the master boot record has been damaged, or that the NTLDR file may be missed. Anyone know how to check this?

• 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 ( answers.microsoft.com/.../f77d5355-b8be-41d6-af24-cae994e1768f ) 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
