CHKDSK - Windows Stuck In Loop When Booting
Jan 25, 2012
When I tried to boot Windows 7 yesterday, I got a prompt saying that a disk check had been scheduled. I initially thought this got stuck because it seemed to freeze on 10% and the numbers alongside that figure didn't go up. I rebooted my computer and let it start again, after a few hours(!) the disk check finished and started on another of my drives. Again, I let this complete and it eventually rebooted itself. Upon rebooting it however, it did the exact same thing and appears to be in a loop just doing the disk check over and over.
I Googled this and opened the command prompt and checked all my drives (it disk checked f and c) but none are marked as dirty. I ran the command to stop the disk check on all drives anyway but still the problem persists.
Right at the start it says I can cancel the check by pressing any key on the keyboard but for some reason, it doesn't work - not sure if it's not recognising the keyboard or not.
I've also tried to boot into safe mode to see if that bypasses it but that hangs at classpnp.sys so that's a no go right now as well. I tried renaming the file to classpnp.old as a forum suggested but it blue screens and restarts if I do that. I'm currently trying a linux boot cd to replace to file to see if that works.

when I registered and put all the information about my computer in you all can see that which should save me some time. I've been running my Windows 7 x64 machine for about 3 weeks without problem. All of my programs are installed on the SSD and the HDD is for data files. Simple. Easy.I run dual display with no problem, 1920x1080 on the 24" LED (DVI), and extended to a 19" LCD (VGA).My dad was kind enough to buy me a 32" 1080p Insignia TV for christmas. I bought a cheap HDMI cable online, and when it came in the mail i decided I would set my computer up to have 3 monitors. (I didn't know that my graphics card only supports 2 at a time, I know this now.)So I plugged in the HDMI Cable to the TV and to the Computer. The 24" LED screen (my main one) Twitches for a moment then returns to normal, the TV comes on, and the 19" LCD goes blank. All is good except Aero magically shut off. After fiddling with the display settings and realizing i can only have two monitors at a time. I decide on the 24" and the 32" for now, but leave all three plugged in. I restart the computer in hopes of returning Aero. THe computer takes a VERY long time to start up and when it does, i'm presented with a dialog telling me that a page file has been created for me.
My page file SHOULD have been on my HDD (to keep room on my SSD, with 8GB of RAM i didnt think page file was THAT important).
I click the dialog and the page file settings open up. i go to check and make sure they are correct, but when i select the HDD from the listbox, everything stops working right. Page file dialogs go not responding. I open task manager and all looks good in processes. Start bar won't open. It looks like the computer is thrashing, but it never gets around to catching up with itself, so i shut it off and try again with the same results.Then i unplug everything but the DVI monitor, the mouse and the keyboard, and try again... same results. Tried safe mode... same results.so i shut it off and let it be for a day (i was pretty frustrated)I come back today, turn it on and it hangs forever on the 'Starting Windows' boot screen.I shut it off and figure.. I didnt have that much on there, I might as well wipe the drive and start from scratch, thats the easiest solution, so i pop in the Windows 7 x64 DVD, reboot the machine, all looks good, and i go for install, and it Hangs forever on the 'Setup is starting' screen with a spinning wheel cursor.One more time i restarted the computer without the disc booted 'normally' and it hung on the 'Starting Windows' screen for a little while, then entered CHKDSK. I let that run, and for the last 20 minutes, it's been sitting saying 'CHKDSK is verifying Usn Journal...'

I was using EASUS partitioning tool to repartition my hard disc a few days ago as my C: drive was running out of space. I merged the C: drive (which is my system drive) with my D: drive (which contains a lot of data as well). All seems to be going well, but after the usual reconfiguration and restart, my windows 7 is stuck in the startup repair screen. Windows is trying to repair my startup without success, which is resulting in a loop. Fortunately i am able to go into safe mode and save my data.

A friend asked me to look at their Acer laptop since it was acting up. It was riddled with viruses so I did a system restore. It is now stuck on a loop saying that Windows could not finish installation. Please restart to finish. I've restarted it several times and am still getting this message. I've used the system restore on several other computers and laptops and have not had this problem.

my computer was not booting up so last night I went to the built in startup repair in Windows 7 and through the command prompt did a "chkdsk c: /f /b" which I saw online. It took about 15 hrs to get where it is at now which it finished the stage 5 and now says "Free space verification is complete." I thought that meant it finished but im assuming not because it won't let me type in the CMD box. Its been at this point for about 2 hours now and im wondering if I should try to shut down and boot up my computer or wait out until it does more. Also during stage 4 it said a couple times that windows repaired bad clusters?

Okay so i have this machine, acer m3100, that originally had windows vista. I tried to do a clean install of windows 7, with an original windows 7 installation cd.Everything would go okay until right after the computer restarts and goes to the part of COMPLETING INSTALLATION. At that moment my screen suddenly flashes with the blue screen of death. i wasnt able to right the error that shows up though. Then the computer restarts and goes to setup devices and right after that an error message appears saying, windows did not complete installation, due to an unexpected restart, restart the computer and restart the installation. If i click okay it will go into an endless loop. Restarting one time after another. So i thought i would install windows vista again. Try to make things the way they were before, but i get the same error. i'm only able to install xp. With XP everything works fine. I do want to be able to install windows 7 though.

I have a windows 7 pro 64 bit HP desktop computer that will not load windows. I have tried safemode, safemode w/ networking, and last know good config. I've run startup repair both from windowsRE and an original windows 7 pro disk. I have attempted multiple system restores (non destructive) to a number of different dates. The system restores say that they work but the machine still loops.
I know it's just some small windows corruption. I would have no trouble backing up my files with a linux distribution live flash drive and restoring the OS but I REALLY don't want to do that. How can I identify and repair the problem without starting from scratch. I'm familiar with msdos cli, but don't know which commands (if any) will help. I also don't know of any live CD's/ tools that will allow me to fix this problem. My problem here is simply lack of information.

when I was playing a game and it crashed on a loading screen, I then could only boot into windows extremely slowly so I knew something was wrong. Since then I have booted into safe mode and done a virus check and it found nothing, I had then done a start up repair multiple times and for one reason or another the system would then reboot just as the login screen is loading. I have recently de fragmented the drive externally and run a slow disk check which found nothing. I've launched start up repair again which says it's unable to fix the problem and I can't boot into safe mode because it'll reboot. I should also mention I was having problems with the drive a few weeks ago where I was getting different error messages before booting but I managed to sort that out. If a solution can't be found it would be safe to say the drive is failing. Here is the bsod when I disabled automatic rebooting along with the startup repair error.

I'm running a Chkdsk/r on my WIndows 7 laptop.The HDD in it has size of about 500 gigabytes, and 400 gigabytes have been used.There's no symptoms of failing recently, but I've got a feeling that it must be checked.So I ran Chkdsk/r about more than 24 hours ago.When it reached stage 4 of 5 at about 36 percent (316831 of 586736 files processed),it seem to be stuck. and It has been the same state for about 30 hours now. But the harddisk is seem to be still active as I can still hear it running. And no, there're no weird voices that came from the harddisk.Is it normal judging by the size of my HDD and the size of its usage ?Should I stop it or let it continue ?P.S. : the chkdsk is running on boot?

While playing on my laptop (SDGO SEA) my laptop suddenly goes black for a long period of time and I decided to restart. Selected "Start Windows Normally" and after the Windows Logo ("Windows is starting") the screen suddenly goes black again like what I had experienced earlier (black I mean black-black, the monitor LEDs do not light up) then the hard drive LED blinks off for about a second, blinks on, off again, then on, and the computer restarts. This repeats whenever I select that mode (I can't seem to see the "Load Last Good Configuration" option). Safe Mode works though (I'm using it to post right now). I tried System Restore but with no luck.:(
I'm not very pro at reformatting, or very familiar on reinstallign Windows (I also don't have a Win7 DVD) so please bear with me XD
Btw,
Acer Aspire 4745G
Windows 7 Professional SP1 32-bit

A Dell Inspiron E1705, w/ 2x2gb mem, 500 gb hd, ATI Radeon x1400 vid and Win 7.There were no Dell drivers or programs and the system BIOS was ver A01. Checking the Dell website against the Service Tag, I found 22 drivers and programs specific to the computer. Most of them ran and installed under Win 7 with no trouble. The last one was the bios flash utility program to update the bios to ver A10. The bios flashed, seemed to go ok. But on system reboot, after the initial screem about resetting the memory sticks, the computer is stuck in an infinite reboot loop.It loads the initial POST screen, completes the POST, seeks for its boot device and when it finds and starts to access the installed HD it reboots. I have reset all the bios settings to factory default settings. I have pulled the system battery and "cleared the cmos", but no joy there. I have created a bootable usb flash drive with another Dell laptop, and the computer will boot from that. I have other bootable cd's, and the computer will boot from them. I can use the bootable cd's to determine that the programs they run (freeware backup programs and a copy of bart pe) can access the installed hd,and see the files there, so the installed hd is intact. But i still can't get the computer to boot from it.My first thought was to reinstall the ver A01 bios, but it would not complete the process and remained at ver .A10. I was able to flash bios A09, and then A07, etc, all the way back to ver A04. But after that I could go back no further, A02 and A01 flash utilities returned an error message. If I found some compatible mem sticks and a smaller hd, installed them, could I reflash bios ver A02 or A01? Would that do me any good? (I have 2 x 256 mg mem sticks from a dell inspiron 5100 which I upgraded to 2x1gb, and a 40 gb 2.5in hd that also came out of the 5100, so I could use those parts in the e1705 to reflash the earlier bios)

i installed LibUSB-Win32- drivers so i could use iRecovery on my iPhone,on completion of installation of LibUSB my keyboard and mouse turned off, well all of my USB was disabled. so i was forced to restart, sadly same thing, login screen no keyboard or mouse, i tried in safemode, same thing. however my keyboard works in CMOS and BIOS so i know its a OS issue. and this only happened when i installled LIBUSB, i looked it up and tried manually removing LibUSB using the Win7 setup disks command prompt. i deleted LibUSB0.sys out of Windows/Systen32/Drivers so that LibUSB wont be called upon during start up, however doing this has now meant my PC will reboot after loading Windows even in safemode, the Starting Windows screen appears. fades and riight before it goes to the login screen it restarts, Safemode too. i have no Restore points and i cannot and i mean Cannot Format this harddisk, its not backed up and i have over 400GB of data i absolutely NEED.Im so stuck its not funny i have no idea what to do to get windows booting again and without this silly LibUSB stuff! i dont have aany PS./2 Ports on my mobo either!, what can i do >? Please ive asked everywhere and no one knows what i can do except reformat.

My Windows 7 ultimate x64 is rebooting itself at the welcome/logon screen, in safe mode only. Normal mode is fine. The reboot happens instantly, after a few seconds at the welcome screen, the screen goes black and the system is rebooted as though I had hit the "reboot" button on the case, with no clean shutdown taking place. I am at a loss to know what could be starting in safe mode, that _doesn't_ start in normal mode, to cause this.
I have recently done a repair install of windows (the problem was there before that), I have tried replacing the safe mode parts of the registry with clean ones downloaded from an AV vendor website (mcafee if I remember correctly), and have tried doing sfc /scannow which resulted in a corrupted boot.sdi being replaced with the archived copy. None of these have fixed the problem.
Obviously, given that I have a usable normal mode, and good backups, this isn't the biggest problem ever, but it would be nice to get it fixed especially for the next time I need to fix a dodgy driver install or similar. What I can check next, particularly in regards to understanding the startup process and what will be loading at the welcome screen that might be causing the reboot.

I went into msconfig on the work laptop and changed the boot to safe boot network, as soon as I went to boot up the laptop and get into safe mode, the laptop freezes at CLASSPNP.sys then I have to reboot.I need to get it to boot back into windows normally, but even selecting "Start windows normally" sends it to safe mode because I set it to boot there in msconfig. What can I possibly do? I've tried running start up repair but says it cannot repair the issue. Due to security, the laptop hard drive has been encrypted with truecrypt, and therefore when I put the OS DVD in to try and do something from the command prompt, there are no OS's listed as installed so cannot alter the bootmbr or any windows files.

The problem is that when I boot my PC it will go black and restart after getting to the windows logo boot part. If I try Safe mode it will get to SYSTEM32DRIVERSDISK.SYS and then just bluescreens and restarts again.Before it got to CLASSPNP.SYS but I tried to rename it to CLASSPNP.OLD and now it didn't really change much. I also tried using this code but it just tells me that some files are corrupt and it cannot repair it.If I try the automatic repair option it will just try and repair for a couple of hours and then say it cannot repair and rebooting the PC.

I have windows 7 home premium 32 bit dell laptop. Lately, it takes more than 10 minutes before it boots before the windows logo appears). From there the computer works normally. I got a suggestion to check for malwares or viruses so that is what I did. I started by going to msconfig and edited the boot options to start automatically to safe mode with networking, then rebooted my system. After booting, it loaded up the initial screen of safe mode, but then it restarted by itself.
I am now stuck on this reboot loop going into safe mode, it won't even let me go back to normal mode. I went to startup repair, but it didn't find anything, so had to reboot again onto the same situation. I have searched for possible answers, and the best that I could get was to remove the safe boot options and go back to normal mode. The syntax to type was bcdedit /deletevalue {default} safe boot but it didn't work, same with bcdedit /deletevalue safe boot.
I am getting this : "An error occurred while attempting to delete the specified data element. Element not found."

So I booted up my PC today and every single time it would get past the windows loading screen, a BSOD would flash on the screen for a split second and reboot. I tried booting into safe mode and that would not work either. The next step I figured would be to format and do a clean install, but here's the thing... Windows didn't even recognize my partition! It has my other 2 HDDs but not my Windows 7 partition. The HDD in question shows up in BIOS, but not in Windows. So, should I just get a new HDD? Startup Repair didn't work either, as it just hung/froze.

So, my computer is stuck in a restart loop. every now and then I see a screen with option to start windows normally or safe mode, but it loops faster then I can hit enter. being a comp guy and knowing enough about comps, tried to load Windows 7 install disk as well as Ubuntu Live Disk.. No luck, loops before they can load. Tried disconnecting everything except CPU, Graphic Card, HDD(3 different), and RAM (1 and all sticks).. No luck there either.

I'm trying to install Windows 7. I've tried a full format and once it saves files and reboots it doesn't continue further it just starts from the beginning again. The HD has come from another PC that was working. Where can I start?

I got a new computer on friday and have set it up today. I installed my windows 7 home premium 64bit and it downloaded,i then went on to put in my xfx AMD graphics card software disk and the download stopped half way through so i started it again and it got right to the last step where it has to re-start the computer. When it started up again insted of loading windows homepage it loaded the system repair screen, it searched and searched but said it had found no problem, so i clicked on the recovery tool restart option that then re-started the computer and the process started again and went straight back onto the system repair screen again. Is there anything i can do to stop it?

I reformatted my hard drive to install a copy of Windows 7 Ultimate, 64bit (I had Windows 7 Premium, 64bit before) and the installation ran just fine. After the installation, it boots up to what I guess is the desktop, waits a few moments, then just reboots. Every time before it boots it goes to the "Windows is loading files..." screen. I also tried 32bit, but got the same results. If you need more information, just ask and I'll be glad to provide it for you. A USB stick was used to install.

my problem is rather odd (or at least I haven't seen it before). Whenever I boot up the netbook it goes right into startup repair, without the option to cancel it, even if I try to start windows in safe mode (or any other startup options for that matter), the system launches the startup repair.The repair itself runs fine (doesn't freeze or antyhing like that), however it is never able to fix the issue ("Startup Repair is unable to repair this computer automatically").
The problem details read as follows:
Problem signature:
Problem event name: StartupRepairOffline
Problem signature01: 0.0.0.0
Problem signature02: 6.1.7600.16385
Problem signature03: unknown
Problem signature04: 6

My wireless won't connect to the internet at work and get stuck saying it is identifying. It works at home. All the other computers in the office work so it must be my computer. I've tried stuff on other forums or just get ignored. I operate a Lenovo V570 with Windows 7 64bit. The internet works when wired. Its just the wireless.

I have a pc that is setup with a 60 gb SSD for Windows and a 2TB RAID 0 for the rest of the stuff. Last night I decided to partition some of the RAID to install Windows 8 Consumer Preview and see what the fuss was about.I partitioned it just fine, and everything was going smoothly, until I decided to use the windows tool to make my pendrive bootable with the Win8 ISO.In the middle of the process, I was doing something else (unistalling firefox to be more exact) and suddenly a blue screen comes up!Now my PC is stuck on the famous startup recovery loop, and I cant find a way to make it boot.
- Manual CHKDSK
- That tutorial on this forum where you mess around with the prompt wnidow
- restarting 1 billion times
- booting up from the windows DVD and trying to repair the hard drive
And as you can imagine nothing happened and I am still stuck with my har drive being unbootable.Now I cant help thinking that this was due to my pen drive being in the middle of that process in some way, but I have since removed it, burned it and buried in a forest, and still my problem persists.Since I havent found another solution online, I think now that the only way for me to get my PC back running is by reformatting my SSD (while hopefully keeping all my RAID files intact) and reinstalling windows. BBUUUTT!!! I have 100s of hours worth of Skyrim in that drive, and if I loose that I will seriously freak out! While I dont play it a lot anymore, when the expansions come, Dovahkin will rise again!Can I copy my files from my messed up SSD to somewhere else, before formatting it and starting a new life?

My system is stuck in a boot loop while booting in safe mode,I was updating the drivers on my video card. I used driver cleaner pro to remove my old drivers. I then used msconfig to boot in safe mode with the minimal option selected. When the computer reboots I get to the screen to type in my password for 5 seconds an the computer reboots itself.

Last night I closed my laptop without shutting it down. I woke up this morning and turned it on and it went to the system repair screen and ran through that. It says there are problems but they are not automatically repairable. I then tried to do the system restore to an earlier point in time and had one option for a couple days ago. I ran through that but it says there is an error and when I expand to see the error one of the things listed is no OS installed. I have windows 7 64bit. Why it would say I don't have an OS installed but it is running through the system start up repair as well as listing a date that I could restore it back to. I have not tried installing the hard drive into a new computer yet.
