Windows 7 64 Bit Machine Stuck In Boot Loop
May 24, 2011
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.

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.

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."

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.

My refurbished Asus g74sx is stuck in a boot-up loop. Because it is refurbished I have no back up discs. I have tried all the advanced boot options with zero success or headway. It has been suggested that I may have corrupted windows files, but I lack the funding to pay for a new disc or professional tech support When I run start up repair the I get a Problem signature reading Problem Signature 04: -1?

i just bought an asus u31s laptop a couple of weeks ago for school and all was great until today. it suddenly crashed and gave bsod. i was just on Internet or something, nothing special, but it had been running for a few hours. so now it won't boot up, it simply reboots constantly. i can't even get into safe mode. bios i can get into, but i'm unable to do anything, since it appears to freeze, when i get in there.

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.

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.

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 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.

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.

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?

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.

I recently build myself a gaming computer the specs are as follows:
i5 3570k
16GB G.Skill 1600 Mhz
ASRock Extreme4
Evga 750 Watt PSU
Asus GTX 670 2GB
After I Installed all of the drivers for everything but the graphics card it was finally time for that and as soon as I downloaded the newest drivers from Nvidia and restarted my computer I immediately got into a reboot loop and any time I've tried going into safe mode to delete the drivers my computer restarts. On top of all of that there are these red vertical lines all over my monitor.

I have a Dell Inspiron and a while ago I shut down my PC and the next morning I was faced with options to repair my computer. It hung on the screen for ages before it actually came up with startup repair and supposedly fixed the problem. A few days later, everything got very slow and started to freeze a lot and before long, booting the computer got very slow as well as it hung for about ten minutes on a black screen after the 'welcome' screen before finally starting up. I decided to reinstall the operating system (I did NOT reformat the C drive), so I borrowed my Grandma's external hard drive and copied my files. After reinstalling using a Dell Windows 7 64-bit Home Premium Re-Installation DVD, I copied and deleted the files off the external hard drive onto my PC (I didn't know it would create a Windows.old folder) and started installing programs. Then I left it overnight to install quite a big program. This morning, somehow it had turned off. I turned it on and it gave me the safe mode options and a 'start windows normally' option. I chose the latter and after typing my password it hung on the welcome screen again. I left it for ages and it just went back to the user login screen again. I pressed the red button in the corner to shut it down but it just hung once again on an empty screen so I did a hard shutdown (held down the power button). I turned it on again...startup repair. It gave me the option for system restore, which I did (then realising when it finished that I hadn't made a backup). I booted it, and again it wouldn't start properly. At this time, safe mode booted fine. After trying various things (even using a compressed air can to get rid of dust) and a few hard shutdowns, suddenly every option from the advanced boot menu took me to startup repair except 'Repair your Computer' which gave the normal options for repair (although now it only gives me 2, Startup Repair and DataSafe Restore and Emergency Backup. Now when I do startup repair, some times it says it has fixed the problem, and sometimes it says it cannot be fixed automatically and gives me information on the problem (a few things it said were: 'StartupRepairOffline', 'AutoFailover' and 'CorruptRegistry').
I can't reinstall my computer because then I would lose my precious files.
Is there some way I can save my files and reinstall or even just save my files somehow or am I screwed?

I was trying to remove some Malware and trojans on my Grandmas computer and sort of crashed it. I was using iObit and I remember seeing something about a rootkit something or another and boot.img file and I did not remove the file as it had the boot.img file, and thats kind of an important file. Anyways after trying to restore and completely reformatting the rd drive, I've had no luck getting the computer past the Windows Splash screen without getting restart windows normally or windows repair options.

I used to think I was pretty decent at computer stuffs until a couple of days ago.I sold my old ATX mobo and replaced it with an ASRock M-ITX motherboard because I wanted a smaller system.However, I didn't really know that I had to delete the old mobo drivers before setting up a new rig. Upon pushing the power button, I am greeted with a black screen stating that W7 can't boot properly. If I press "Start Windows normally" it bootloops. Thus, I downloaded Hiren's boot cd and followed the instructions from this thread:

I've found the Fix HDD controller program, but my 500GB HDD (which stores my W7) is not recognized. It is recognized in the UEFI BIOS, but not in miniXP.
