Y700 m2 upgrade - continuous reboot loop cycle?

Hi all

I recently bought a Y700 laptop with a 128 GB m2 and 1 TB hard drive.

I found that the 128 GB drive is just about acceptable, but as I do photography editing, the drive working essentially consumes the rest 30 GB I have free instantly. I would also like a little more room for manoeuvre for failing to manage the storage space so closely.

So I bought the following:

Samsung SM951 M.2 PCIe SSD 512 GB
SM951 Series MZHPV512HDGL-00000
Capacity - 512 GB

I read NVMe version is not supported, but I assumed it would work.

I tried to use Acronis True Image clone/backup the existing drive, actually a recovery disc and used to restore the backup to the new drive. So far, everything seems to work.

However, after reboot, first of all, I got a BSOD message saying "Inaccessible_boot_device" and then the system reboots. At this point the loop starts, the screen shows the text "LENOVO" on black for about 10 seconds, switches and 2 seconds later goes on to repeat the process to infinity.

Thinking it was a problem with Acronis, I tried to use the Installation of Windows Media disc for just fresh install windows on the disk. Once again, everything seems to work and has been installed properly. However once the installation has been completed, once again reboot loop began.

I must add that when the loop runs, hitting F2 or any other key does not work, so I can't access the bios to tell the computer to boot from a key USB etc. To exit the loop, I have to power off the laptop and remove the offending SSD drive and then restart. At this stage F2 works, allow me in the BIOS to re - assign the USB as a boot priority to try to restore media etc.

I also tried to do "repair Windows startup", but after a few minutes, the repair process said that he could not repair the drive.

At this point, I wonder which of the following occurs:

1 drive is defective

2 - the drive is not compatible (material)

3. drive is incompatible because of outdated drivers (the laptop is 1 month old)

Any help you offer is appreciated, because I doubt now, I can return the drive given the way it has been used now!


An apparent difficulty has been to change the UEFI boot to legacy mode, but I kept the UEFI as first priority in the boot sequence. Things seem to work fine now.

Weird that the 128 GB m2 player provided by Lenovo was beautiful on UEFI, yet my 512 GB there is no work?

  • 0 x 00000024 reboot loop

    I rebooted Vista recently it was very slow, and it got stuck in a continuous reboot loop. Startup Repair also fails to load correctly and restarts until I can do something with it. They showed me a BSOD with an error message after turning off the auto reboot:

    Stop: 0 x 00000024 (0 x 00190444, 0x86ec9940, 0xc0000102, 0x00000000).

    They tell me to run chkdsk, but don't know how while I can't in Vista at all.

    Safe mode is stuck at crcdisk.sys and restarts.

    Any ideas? How can I run chkdsk without going into Windows?

    Alteration of the disc or the material associated with the operation of disk (hard drive, wiring and controller of the motherboard),
    lack of enough system memory, BIOS and antivirus/antispyware/security programs may have a role.


    BCCode: 24 0 x 00000024


    One possible cause of this bug check is damaged drive. Corruption in the system of NTFS file or defective (sectors) on the hard disk can cause this error. Corrupted drivers SCSI and IDE may also compromise the ability to read and write to the disk system, so causing the error.

    Another possible cause is the depletion of memory pool non paged. If the nonpaged memory is exhausted, this error can shut down the system. However, during the indexing process, if the amount of memory available nonpaged pool is very small, another driver in nonpaged kernel memory in pool mode may also cause this error

    Solve the problem

    To solve a problem of hard drive corruption: Check Event Viewer for error of SCSI and FASTFAT (syslog) messages or Autochk (the application log) that might help determine the device or driver that generated the error. Try disabling any antivirus software or Disk Defragmenter tools that continually monitor the system. You must also run the diagnostics of material provided by the manufacturer of the system. For more information about these procedures, see the manual of your computer. RunChkdsk /f /r to detect and resolve any file system structural corruption. You must reboot the system before the start of the analysis of disk on a system partition.

    To solve a problem of impoverishment of nonpaged memory: Add new physical memory to the computer (which increases the amount of memory available to the kernel nonpaged pool), or reduce the number of files on the volume Macintosh (SFM) Services

    Schedule chkdsk to run at next boot (checkdisk).

  • Continuous reboot problem

    HP DV6000 laptop

    -Intel Core Duo T2450 2 GHz

    -1 g RAM

    -Vista Home Basic 32

    Portable colleague brought me, wouldn't boot Windows.  Diagnostic hard drive with physical failure, cannot be accessed by car, even using Linux OS and Test drive.

    I replaced the drive and used the HP to reinstall Vista drivers and HP system recovery disk.

    After all, I'm having an issue where, after Windows starts, the system will restart spontaneously after about 30 seconds now.  This cycle continues until the system is shut down.  Problem does not occur when it is started in Mode without failure.

    Has seen a similar post suggested reinstalling the RAM, which I did, but still have the same results.

    Any suggestions?


    After more than web hunting, found what seems to be the issue.

    HP apparently uses a program called Manager of GUI of FBI to reinstall Windows, HP drivers and programs from the recovery disc.  This program seems to be buggy, where after all has been installed, it is stuck in the reboot loop.


    Start > run > MSCONFIG > startup

    Disable RUNFBI

    OK, restart

    Will be no longer stuck in the loop of reboot of the system.

    Delete the c: APPLZIP folder to remove the GUI of the FBI program.

    Problem seems to be resolved, will display again if not.

    Resolved on mine, but I hope it helps someone else with the same problem.

  • Reboot loop infinite blackBerry Smartphones Blackberry 8820

    Here is what I tried:




    which breaks down basically to remove the battery and attempt to restore the operating system (it seems to work until the BB reboots, then he jumps in the reboot loop) and using the JL_Cmder to wipe or resettofactory.  No matter what I try (or where in the startup cycle I try), nothing seems to work.

    Is there some special gotcha that I'm missing?  I need really just my phone at work. Thanks in advance.

  • The update of Windows 10 1511 reboot loop Bootcamp BSOD ACPI. SYS

    It is a copy of my thread to http://answers.microsoft.com/en-us/windows/forum/windows_10-performance/windows-10-update-1511-reboot-loop-bootcamp/8653... as I was asked to post here by the Microsoft Support Engineer.


    Friday night, I went to bed with a working machine. I had a late 2013 Mac Pro BootCamp running with a Windows 10 Pro installed, the Build version before 1511.

    On Saturday morning, I woke up to my PC restart itself over and over again. It seems that Windows Update has decided to put a new version of Windows 10 on my machine without my knowledge. I discovered this after restoring an acronis backup (which took a few hours because of the number of incremental backups)

    Occasionally (about 1 in 20 restarts) it would blue screen with an error:


    But the rest of the time he would just start, flash a window for a millisecond that says (I think) winlaunch.exe, then restart.

    I tried a lot of things to sort it, including:

    (1) restore from a backup, acronis to Friday morning, running sfc/scannow, and then runs the update

    (2) the creation of a recovery USB, enter the console, change the boot to legacy method, so I can F8, then goes into all security modes and mode of illegal product, but I can find where windows 10 now puts the boot log

    (3) restored from acronis, switched to mac, created a new bootcamp drivers usb, switched to windows and run the option 'fix drivers' before performing the update.

    Ntbtlog.txt is not anywhere on the partition. I ran a dir /s > a.txt then open this a.txt in Notepad and searched him.

    I don't know where to go from here. I can acronis restore of a windows 10 work machine the morning before installing mandatory 1511. I don't know how to delay the update no more, I noted during a restore I had delay on updates that are why it has arisen just now.

    I do not know how to find where this BSOD ACPI.sys will come (even if it happens so rarely) or this that its trying to load just before it crashes (so I can try to delete the driver etc. by the front restored windows to upgrade)

    I guess the widowed causes 10 to do a restore, then the restore fails.

    Overall, I get at the end of my wits with this, to go a completely Windows 10 installation work Friday to more than two wasted days, restore backups, try again, rinse and repeat. It's now Monday morning and I am posting this as a ditch last attempt to solve the problem, your help would be appreciated.

    If you need more information please let me know the location of the files, etc, or their names and I will do my best to have copies available for you.

    I will now restore the backup again, uninstall loading of drivers, and then try the update of windows for the 4th or 5th time.

    Thanks in advance,


    Woo Hoo, I've solved the problem!

    I uninstalled the drivers of graphics from AMD (with AMD Driver Cleaner) and Arcronis True Image Home 2013 at the same time, then let Windows Update run its course. Now I have a machine with Windows Version 1511 10!

    It took me 4 days of downtime...

    I hope this helps someone else.

  • continuous reboot of failed reset

  • Computer goes into a reboot loop after installation of an update

    Original title: Windows Update on August 12, 2011

    My laptop has done a windows update this morning, don't know what he did, it was very fast now, everytime I turn on windows trying to open then fails and continues to do this in a loop.  Please no technique with the help of numpty here!


    1. what update has the problem from occurring?

    Follow these steps and check if the problem persists.
    Step 1:

    You can check if you can "disable automatic system failure reboot " from the options in advance. In this way the computer will not go into a reboot loop and you will be able to note the error code, if any. If you see no error code, you can answer comes back with the error code.
    Step 2:
    I suggest that you start your computer in safe mode and check if the problem persists.
    Step 3:
    If the system works fine in safe mode, I suspect that there could be a conflict of software of third party causing the problem to occur. I suggest that you start your machine in a clean boot State.
    Note: Follow step 7 to your computer as usual.
    See the below article access in Event Viewer.
    Open event viewer

    Step 4:

    Updated version has a problem in the history of the update.
    a. open Windows Update by clicking on the button start. In the search box, type Update, and then in the list of results, click Windows Update.
    (b) in the left pane, click view update history.
    c. to display more information about an update, double-click it.
    Do System Restore to the point that your computer worked very well and install updates manually ensuring that do not install the problem causing the update unless it says 'important update '.

  • HP Windows 7 stuck in a reboot loop

    Hi all

    Recently, I accidentally upgraded my HP Envy 14 from Windows 7 to Windows 10 and let the month pass without switch back.  Due to one host of other problems that have arisen, I decided to Windows 7, so I took out my old Windows 7 recovery disc to re-install Windows 7.

    He successfully reformats the hard drive and everything seems to go well until the end of the installation, when all of a sudden it shuts off and restarts.  He will then get as far as the 'starting windows' screen before it restarts again, each time giving to the screen "Windows is not stopped successfully", is not just a part of the installation process.  He's stuck in this reboot loop.

    Any advice?

    Couple comments:

    I have created a startup repair disk and ran the Startup Repair, but he reported having found no problem.  Very well.

    When you try to start the computer in safe mode, I get to the screen "Windows is set up your computer for first use" and then informs me that Windows cannot complete the installation in safe mode.  He gets up to now in normal mode, however.

    The battery is thus burned - can install Windows on a computer that has failed the test of the battery?  I don't see how there would be a relationship, but I'm really running out of ideas.

    Thanks for any help/insight you have!

    Eventually the recovery disc files are corrupted, try the following:

    Download Windows 7:

    For 5 years, Microsoft made it fairly easy for users of the Windows 7 operating system to get reinstall media. If you have lost your support disc or installation retail collection; either it has been damaged or defective; You can download a copy of the edition that you have licensed from a membership site called Digital River. More recently, Microsoft ended the availability to reinstall media that you can download as a. File ISO in Digital River, which is a digital reproduction of an optical disc.

    It was particularly convenient for people who could not easily get the manufacturer's recovery media, did not want to pay the fees required to get or preferred a clean configuration without the software packaged manufacturers or even a recovery partition does not work. It's easy to use, all you had to do was reinstall and reactivate using the product key located on the certificate of authenticity and download all the drivers on the manufacturers website.

    Given that this option is no longer available, what are your options? See the article for more details:

    How to: What are my options for Windows 7 reinstall media?

    Make sure you scroll down and read the section:

    What to do if you cannot get your manufacturer recovery media, refuse to use or to buy it or the Microsoft Software Recovery Website does not work?

  • Pavilion dv6636 stuck in a reboot loop with no boot


    I have a Pavilion dv6636 purchased on Oct / 2007 which saw a reboot loop with no boot. By pressing the Start button, I can see the hood leds on, power on (as well as the port for illuminated around blue AC adapter), HD led being turned on once and can hear the pilot DVD is powered and the fan turns, then, after about 10 seconds (while the screen is always black), he stops, remains off for 5 sec , then restarts, stuck in this loop. Experiences I've already done:
    -hard reset
    -reset of memory
    -stable memory locations
    -exchanged memories
    -started with memories (sounded a beep as expected)
    -had started with HD (continued with the same symptoms)
    -F8 or F2 keys pressed during startup (black screen and continued with the same symptoms)
    -F10 key during startup (by pressing F10, it does not shut down as usually does, but rest died, with black screen and rotation of the fan)
    -external monitor plugged in when you start (black screen and continued with the same symptoms)

    Same question occurred in about 4 months ago, but at that time, after break of a week I tried to start and has been a success. Not at the moment.

    Please, any thoughts of what could be the problem?
