Installation :: Lenovo ThinkCentre Upgrade Ending In A Reboot Loop
Aug 8, 2015
Lenovo ThinkCentre, 32bit was running fine on Windows 7 Home. The upgrade to Win 10 downloaded fine and started installing until the final bit Settings etc when there was a brief error "KMODE EXCEPTION NOT HANDLED" without any further info. No codes, numbers or anything else. Installation continued until 97% and then started rebooting in a loop for several hours already.
I'd prefer to finish the installation properly, but otherwise would like to roll back to Win 7 and have a usable machine with all data and programs intact.

I ran the window 10 installation last night on my Lenovo Y50 laptop. Today it is stuck in an endless loop of trying to Preparing Automatic Repair, diagnosing PCs and wanting to restart. I can't get past the limited choice of options to actually do anything useful. I just want to get rid of the thing and go back to Window 8. I am to computer stupid to know how do this. I only recently got the laptop. I don't have a recovery disk.

My windows 7 PC was hard to start and restart and I needed to try 10 times or more before it worked (then I didn't restart it for days).
I managed to upgrade it to Windows 10 hoping that it will cure the problem BUT still it is a problem to start.
I checked everything and used every tool possible on windows 7 and windows 10 but nothing worked. (ccleaner and others failed)
So now I have a windows 10 PC that doesn't want to start easily.
After upgrade to windows 10 I GUESS that all driver files have been changed ?what else could it be ?

I did an in place upgrade of Windows 7 using a USB key made with the tool Microsoft put out. I chose not to download updates during the install, so after the initial boot, Windows started downloading updates. I reinstalled the latest nVidia drivers/Geforce Experience as well. During the next boot cycle, at some point explorer crashed and the screen flashed black, at which point that process repeats forever. I let it go over an hour just to see what would happen. URL...
The suggestion on that site is to disable 2 Windows Services: Problem Reports and Solution Control Panel Support and Windows Error Report Service. This didn't work for me, though it appears to have worked for many others.The culprit for me was Apple's iCloud service. As the taskbar was being populated, this task would load and throw an error message about logging in, at which point the crash loop began. Uninstalling this program solved the issue for me.

I was using a machine with Windows 7 Ultimate 64bit, and it was working perfect till the day I upgraded to Windows 10. First, I had a few problems during the update, probably due to the not updated (with the last drivers) nVidia card.
My specs:
-SSD hard drive as boot
-MOBO is Gigabyte GA-768XP-UD3P updated with the lastest BIOS from 2013, UEFI.
-a few other hard drives
-nVidia GTX 980 graphic card
Well, I finally was able to install the Windows system, but after the shut down and boot, I couldn't enter it. The computer started to reboot after a few seconds, sometimes I'm able to see the BIOS screen (but pressing any button doesn't work) and then it boots again in a few seconds.
After some search online, I understood it could be a problem of the BIOS that was corrupted (why if it worked till the day before??). I used a very strange system to press the power on button and put down and up the PSU for 3 times, then when I rebooted again I saw the screen with "The main BIOS is corrupted and we have to recover it from a backup".
The setup of the BIOS from backup worked, but with "load optimized default" I then got a Windows 10 blue screen error " :-( INNACCESSIBLE_BOOT_DEVICE"
I then entered again the BIOS and changed some info like AHCI, UEFI only, etc.
Then, after a reboot it worked and I could enter WINDOWS 10 finally.
I thought I was OK, then I tried a reboot and it worked. BUT, when I tried to first shutdown and then boot, again I went inside the BIOS reboot loop!!

I was running the Win 10 build 10074, in the slow ring. I left it unattended for update, which included the newer build 10130. Before leaving, it was at 99% downloaded. When I returned after 30 mins, it was stuck in an endless restart loop.
It restarts within 2 seconds of displaying the Windows logo, when I try to boot from the HDD. If it goes into Automatic Repair, it shows "Starting automatic repair" under the logo and restarts after some time.
But the worst thing is that the same problem occurs, Even if I try to run Windows 10 setup/repair from a USB drive!! (build 10130). It just reboots a few seconds after showing the logo, even when I removed the HDD. I am totally stuck. I am currently running Ubuntu from a USB drive, which is working just fine.
I am not sure what happened in my absence, though it's unlikely that the newer build was installed in just half an hour. The only idea thing that I can think of and have not tried is to try running an earlier build or version from the USB drive.

During startup automatic repair launches, restart ensues, that's the loop. The error mssg is WDF violation which it seems is related to iTunes. I just can't get out of this loop to do anything about it. I don't have a boot disc. Safe mode is what I would like, but that doesn't work.

I chose the "fast" ring update on the windows insider app in order to get the preview for windows 10 on my lumia 1520. It updated fine but since the migrating data process began, it has been stuck in a continuous reboot loop. The screen shows the nokia logo and the windows logo briefly, then shows the at&t logo (since I bought the phone in the US) with "not for resale" written in the bottom left corner. How can I fix this? I don't mind losing all my data.

I recently received the Windows 10 download on a desktop PC. The installation seemed to be going swimmingly however desktop suddenly powered off. Upon reboot, I'm stuck in a vicious failure loop. I tried to restore to no avail and tried to boot Windows 7 from a physical disk, but no matter what I try it appears my desktop PC is history. It ran Windows 7 just fine. I really wish I hadn't pushed my luck with Windows 10.

After the upgrade I performed a "Reset this PC" with "Keep my files". Periodically the WiFi will die. No networks will appear in the list in the pane which appears when one clicks the icon at the bottom right.The fastest way to fix it is to click the left-most button twice, which seems to disable/re-enable and automatically reconnect to the network. I have checked the router. The problem is not manifesting on another Lenovo laptop upgraded the same way. I am using the latest available network driver.So far I haven't performed a clean install due to the time it will take.

I upgraded my Lenovo Thinkpad Tablet 2 to Win 10 a few weeks ago. Since then, it won't fully power down 9 times out of 10. I close all apps, and select shut down from the power menu, and it appears to go through the shut down process, but it stays powered - the haptic feedback Windows button buzzes when pressed. If I don't plug in the charger it will kill the battery.
The only way to power it back on is to hold down the power button for 15 seconds.

The touchscreen has stopped functioning since the recent Windows 10 upgrade. Everything else works great. There are no new drivers I can find yet Lenovo claims that this device is Windows 10 compatible.

Although, the upgrade this morning initially was successful - it did reboot into Windows 10. When I restarted the machine, it's now stuck in the setup repair loop. None of the options seem to work, even if I try and have it reinstall windows while keeping my files, it still restarts and goes back to the setup repair. I really don't want to do a clean install as I didn't make a backup of my files (which I will always do from now on).

Do you think that the problem can really be a driver ? After upgrade to windows 10 I GUESS that all driver files have been changed ?

My laptop is running on Window10 efficiently. Sometimes in order to check the DVDs and USBs bootability of newly created OS or Recovery Disk etc I have to select the relative option in the the bios. But on Lenovo G 50 70 the selected option is not permanent. You have to select boot priority option repeatedly for each and every USB/DVD that I want to check. Can i set these option permanently like:-
1st priority USB
2nd priority DVD
3rd priority HDD
4th priority Network IPV4
5th priority Network IPV6
There is a novo key to access the bios in Lenovo Laptop G 50 70.

My laptop recently got hanged, then I restarted the laptop. But right from the booting Windows 10 screen, a music is being played in background.
Nobody uses my laptop since 1 year apart from me. And I never did any such settings. Here is the link to that audio I recorded from my mobile phone. [URL] ....
I can't see any such processes running in Task Manager as well.

I elected to postpone the Win 10 upgrade for two days to allow me to save an image before installing the new OS. However, when the process requested a restart, I naively went ahead and to my horror, the Win 10 install was underway
As all too often in these situations, the install on my Dell Laptop (Win 7, Home Premium), stalled at 44%.
Hitting the reboot key had the install attempt to reinstate the original OS. This failed.
I'm presently in the situation where a reboot asks for the Win 10 installation disk, to enable a reinstall (I presume). Obviously I do not have an installation disk.
Not to be deterred, I attempted to reinstall a relatively recent Win 7 image using my Dell software recovery disks. Things seemed to proceed in an orderly fashion until at a point I received a blue screen of death a consequence of the disk software saving my computer from terminal damage (as if I wasn't terminally damaged anyway) .
Now, as we all know, at any given time there is incremental data on our disk that will be lost in any format, even in the event of a successful past image recovery.
I guess the question is this: If I were able to access a Win 10 installation disk, and use it, what is the likelihood of this screwed installation recovering itself in such fashion that I end up with a Win 10 OS and my data intact?

Upgrading from windows 7 to 10, started install at around 10:30am and left it....around 2:30pm it started the large circle with the % in the centre, and again left it for another hour or so and came back to a black screen, no cursor or anything.
I waited until about 7:30 and still nothing and did a reboot by holding the power button down. On restarting, I get the windows 10 logo with the spinning dots, and then it cuts to black with no cursor. The CPU light does what it would usually do on startup, and when it first cuts to black but then the screen seems to change to a different black (if that makes sense?!) and the light only blips extremely quickly with a long period before it blips again
i know this is another update gone wrong post but I can't seem to find any with the same problem, just similar ones. I've read it can take a long time, but it's been nearly 11 hours and is very frustrating!
i'm not mega pc savvy, I get 2 options when I boot, and I've looked and there's no option for me to do a safe boot, or to revert back go windows 7. If I leave it on black screen for too long it automatically goes into sleep mode.

I'm using HP 15-n061sr with Windows 10 SL and SSD Plextor PX-128M6Pro.
Right after the upgrade from Windows 8.1, I started to experience SMART error on reboot, and only on reboot. I mean that if I just turn the laptop off and on it doesn't happen. It says that SMART detected a possible imminent failure of my disk. If I press "Continue startup", it says something like "insert boot device" or that it can't detect an operating system. Then I can go to BIOS options and restart from there - it boots up flawlessly. This happens every time I reboot. I upgraded 2 days ago. I have the latest SSD drivers. I used Windows' disk optimization tool. SSDLife Pro says disk health is fine.
P.S. I once had imminent failure problem with my previous SSD, but it happened once and it never started again; I got the refund under warranty.

I have been trying for hours to install windows 10 home on my newly built PC but i can't because there is a problem. I bought the usb version since i don't have an optical drive bay.
The problem: I can start the setup, but when i launch the installation my pc suddenly restarts and boots the usb again, so i get back at the 32/64 bit selection screen. This happens when i click "next" after choosing my drive (see included video). The drive i'm using is a Samsung 850 EVO SSD.
I have tried numerous things to fix it including: removing the ram (2x8GB) and putting it back, trying with one ram stick, removing the graphics card and use the integrated graphics card, use different usb ports, use different sata ports, removing the hdd (i can't even start the setup with the hdd plugged in).
I also downloaded Windows 10 from the official website and put it on an other usb stick, the same problem occurs.
I even tried with Ubuntu and the same problem happens!! When i launch the installation my pc reboots and the setup restarts!
I have made a video showing what happens (win 10): OS installation problem - YouTube
I also made a video that shows my BIOS: Gigabyte GA-Z170X-Gaming 3 BIOS - YouTube

I tried to update my Windows 8.1 installation on my Thinkpad T61p to Windows 10. It went smoothly until it finished copying the files (75% complete). It is now rebooting in an endless loop (reboot -> Windows logo with spinning circle -> black screen -> Windows logo with spinning circle -> 75% complete message -> reboot) and I don't know what is causing the problem. I have installed the latest BIOS and tried various changes to BIOS settings with no effect. Does the installer write any kind of diagnostic log that would tell me the reason for the reboot loop?

I recently upgraded my Windows 7 PC to Windows 10 using Windows Update. The whole process was smooth. I never really ran into any problem. Because the PC is so relatively old, I decided to delete all files and reinstall windows 10 using the windows 10 feature 'Reset This PC' to start fresh and theoretically faster. During the reset when Windows is installing my drivers, I noticed that the screen is plain black - no mouse pointer and the amount of reset finished(in percentage) is not also shown. The screen is just plain black. I am pretty sure that both the monitor and CPU is on. I've tried waiting for atleast an hour. I turned my pc's monitor on and off - nothing happened. So I have to resort to hard reset/reboot coz I cannot really see anything on my screen.
When I turned the power of the CPU back, it gave me the error 'The computer restarted unexpectedly or encountered an unexpected error. To install Windows, click ok to restart the computer and restart the installation'. I pressed OK but after restarting, it gave me the same error over and over again. I tried the solution in this website ( during installation of windows | HERESJAKEN), and it got rid of the error. However, I am stuck yet again in a loop that continues to just restart my PC when they reach the screen that tells you how much of the reset is finished, in my case, im stuck at 64% of the reset. That screen is shown for like merely 2 seconds, then the PC will just restart again, then show the "Reset progress screen" again for 2 seconds then PC will just restart again, over and over. I think the only solution is to start the reset of the PC again, but I dont know how.

Have just installed 10 on a spare drive and installed that drive into my Sandy Bridge and the machine is now going through an endless loop of start up.
I can hear it make some sort of noise as if something wants to go and I have again tried the machine with the old 7 install drive and the same thing is happening.
The other thing is I am not getting a RAM beep or the BIOS to come up on the Gigabyte board (DEL) have jumpered the reset pins for the BIOS but still no BIOS or for that matter any graphics.

My installation is stuck in a reset loop. The Win 10 Ready to Install came up, so I clicked Start and it rebooted, back to the login screen, and then Windows Update came up saying it needed to Restart Now. After a couple of minutes the Win 10 Ready screen comes up again. I've rebooted about 20 times and get to the same point every time.
