PC startup error, Preparing automatic repair, Diagnosing your PC

This morning, I received an error when starting the PC, it remained in a boot loop, displaying messages load: Preparing automatic repair, Diagnosing your PC or Attempting Repairs.
The night before the flow stopped for a few seconds and your PC suddenly closed, and remains closed after power recovery, since so I set the bios, to remain stopped if a power stops unexpectedly.
When I started I found the problem and wanted to fix it somehow. Unfortunately all trying, it was nothing. I searched the net and solving most of the advice sent me to reinstall your operating system; An operation quite time consuming nerves. I have several applications installed, each with its settings, I did not want to lose them all.
Dissatisfied, I began to try somehow recovery, especially as it seemed a problem easily resolved. After a few hours I managed to restore deleted files from corrupted boot with a stick that I put Windows 10.
These problems can occur when:
When restarts suddenly and unexpectedly PC
It stops feeding,
When an update is interrupted suddenly,
When you connect to a PC hard drive with another operating system,
When we set incorrectly dual boot configurations,
When we Matrix RAID drives defects.
When different hardware change
When we have a silly BIOS settings
In the tutorial I showed everything from how they look nasty messages, to boot successfully. In addition we covered a few options in the recovery menu, to see that the problem can not be solved with the recovery menu on the disk are absolutely necessary to use a stick or DVD with Windows 10 from which it will repair the problem .
For those who do not know to make a disk or stick with Windows 10:

In some cases, it is likely to be bigger problems. You can have physical hard disk problems or problems with the SATA controller.

2. Boot from the stick or DVD
3. Choose: Computer Repair (no installation).
4. In the blue window we choose “Troubleshooting / Complex Options / Repair at startup.

      Win10 is an OS for power-users or people with the capacity to adapt, in any event for amateurs or the faint of heart.

    Hello. I'll try to be brief, but I do not think to succeed, because you have to details.
    I dualboot on an SSD: Windows and Windows 8.1 10. Mergin this option for several years, beginning August last year making updates from Windows to Windows 7 10.
    For several days it does not start normally on any of the OS, doing exactly as in the tutorial: Preparing automatic repair, Diagnosing your PC, after which it does not start, loading - maybe - restart, and after selecting any OS, displaying the logo with the blue window and then … .Black screen.
    If I have patience, leaving him so it was possible several times to take the place after 5-1-15 minutes.
    I mention that during this system seems to work in the background as the HDD LED blinks, or if you insert a CD or stick
    It crossed my mind not to be tied to the video driver, so the two of loads successful, I installed another driver (last) on both OS, but the phenomenon persists.
    My solution (absolutely annoying and which I do not accept indefinitely) is - just for the moment - Restore File Reseved with Acronis from a previous backup made with it.
    My question, if you know more, what phenomenon, what happens to this 100MB File Reserved ?! It is altered, or what ?! The system, after this File Reserved Restore, loads only primul until the first Restart. Even if I try booting from the other OS, it doesn't work, except after the same Restore.
    What to do?! I tried once, about a month ago (in the same case) total Restore each OS separately from previous backups, but not resolved. At one time he could walk normally, but only until a few days ago. So ?!

    • Why dual boot windows and windows? "So ?!" 🙂

        To use PC-fecioru me and my 14 years.
        I do video processing and I want to keep my system as clean (especially partition with OS Win 8.1) and he wants to clamp on 10 Win (100% games).

        • YES, in this case yes, I have nothing to comment in vain but if you just got complicated to have 2 windows how many problems does it have… plus it's a virtual box or a bone on one hard on each other even though it costs

  8. I had the same problem a few days ago, we solved quite simply. I turned off the PC 5 minutes after I lit it worked perfectly.

  9. Hello
    Question: You gave a check disk?
    if you gave in writing tutorial thing I'm sorry I missed
    a good day

    • Adrian Gudus said

      You can not apologize for things you do on purpose. Your problem is that you have undertaken and as a logical consequence, you lose when you said exactly what you're asking.
      With intent to do an act whose consequence is deduced by simple logic and then apologize, is called hypocrisy

    I'm Sorin, please help me, in connection with an E-boda phone, he writes to me on the phone screen: "unfortunately the tool system has stopped", I must also tell you that in the past I have been installing different applications myself and someone he told me to root my phone, he didn't tell me how, he just told me that rooting is done with two applications that I still have installed on my phone, so I didn't have time to root. I didn't even know how to do that, I just downloaded the applications, a Superuser and Frama… I don't know how. Okay. If you can help me. The phone is an E-boda dual sim Eruption V200, quad core. Thank you.

  27. I hate w10. I switched from 7 and now no game is working properly. W10 tends to confuse video drivers hard. I think I will switch back to 7. I understand that w8.1 would be the best system operation at the moment but I don't have a license so… Maybe Cristi explains why w10 "disturbs" video drivers like this and if microsoft does something about it.

  32. I forgot to say that I tried to rejoin win.10, but without success, does not boot either on the DVD or on the stick. I have a clinker pc with a central unit, the old 12 years. I await suggestions, thank you.

  33. Mr. Cristi very good tutorial, as well as all the others for which you deserve the congratulations and pleats
    ours, of the least or no good in IT
    But I have two suggestions for your tutorials
    1 - the method or methods that work, about uninstalling or repairing deep freeze installed with the frozen C, which does not open with (shift + double-click the icon) so they can thaw it out. I can not uninstall it anymore, I went to 2 for years and now I do not want to open any color. That's on the base PC because I installed the same deep frees and that's where it goes.
    How can the problem be solved differently, except reinstallation.
    2-a detailed installation tutorial (what to accept and what not the questions asked), setting up and
    using BlueStacks.
    .Thanks in advance.

  34. Poor chances, or more likely, only 25% of cases.
    Installation is the most likely event, if you get into this situation.

  35. I've been reinstalling the windows and not holding 2 for hours, and this problem is happening again. I have reinstalled him since I do not know how many times and all this is happening to me; What's the problem with?
    Please, I quickly want a safe answer, because of which component these figures make! I've searched and think because of the hard drive but I'm not sure!

  36. Explain extremely stupid!

  37. When I try to boot I get Recovery Your pc / device needs to be repared, what can I do?

  38. Hello Cristi!
    I have a problem with the PC, namely it does not boot

  39. Hello.
    I had a computer that I shared with my wife and daughter .PC did not allow me to install Win x64
    I had 3 HDD with Win 10 Pro x32, 2 hdd Sata old 2 and HDD satin 3 by 1 tera.
    On the old PC they went smoothly and we checked them with F8. For the old PC I had Video integrated in the Board
    base but I used a gt8600 Video Card and I had 4 GB Ram.
    We took a PC today with UEFI, 8 GB Ram, and integrated video that go with being better than the old GT 8600.
    This is the historian.
    I moved only the 3 HDD with their systems to the new PC. It saw them and adapted to the new PC immediately.
    smoothly . In this mode I walked about 2 months without incident.
    After 2 months I got an 128 M2 Sata SSD on which I installed Win 10 X64.
    All good a few days after the trouble began. Without having problems with feeding appears
    notification with "Scan drive error" or nothing appears but when restarting it enters the bubble mentioned by you
    Sometimes a long text appears at the bottom of the screen to repair drive x and finally I woke up to find a
    3 HDD partition on either one, either primary, logical or System Restore,
    I blamed the SSD and dropped it.
    Last days I installed the XDUMX Win 3 Pro x 10 from the MS on the HDD.
    Towards "My Joy" the same troubles began. So it was not the SSD that was to blame, but Win 10 pro x64.
    The trouble is that it does not scan the OS partition that has X64 win but hits in another HDD which sometimes
    even delete it.
    Now I'm afraid to use x64 again. Lucky I had clones and solved faster.
    It's twilight.
    Does anyone have any idea.
    Cristi, after you solve with the Win Disk the moment is solved or the problem reappears?
    PS. If anyone resisted to read my POMELNICUL and especially to understand… ..I give a beer
    big .
    Long and prosperous life.
