the tip to run SFC -- I'm not sure where the 'command prompt' is now in Windows 7.
What I did was search for sfc, right click, then run as administrator.
It appears something is running, but no window opened to ask or tell me anything. I checked Task Mgr and Resource Monitor and can't find anything resembling SFC, but there is activity even tho' I'm not doing anything else. The hard drive light is also flickering about once per second. What should I expect? Do I just wait patiently? How can I confirm SFC is running and fixing any errors?
System File Checker (sfc) has a few parameters that you can use when runing sfc:
Parameters /scannow : Scans all protected system files immediately. /scanonce : Scans all protected system files once. /scanboot : Scans all protected system files every time the computer is restarted. /revert : Returns the scan to its default operation. /purgecache : Purges the Windows File Protection file cache and scans all protected system files immediately. /cachesize=x : Sets the size, in MB, of the Windows File Protection file cache. /? : Displays help at the command prompt.
What's the difference between the first two, /scannow and /scanonce?Does /scanonce wait until you reboot and then run one time?And while I'm asking about sfc, where is the "Windows File Protection file cache"?
Corrupt files in System File Checker - now whaIn trying to fix a still unsolved problem with my WLAN network connection (detailed here, if relevant: WLAN issue - WiFi can't connect - Tech Support Guy Forums), it was concluded that a main problem is corrupt files identified by the System Files checker.This is the message I get when running the checker toold corrupt files but was unable to fix some of them Checking the log, I searched for cannot repai but nothing comes up. Searching for in the logs turns up some cases of annot verify component files for Microsoft-Windows-Security-Kerberoarch for turns up nothing. Not sure what to do now. My computer is a Dell XPS 15 Z
1. At an elevated command prompt, type the following command, and then press ENTER:takeown /f Path_And_File_NameFor example, type takeown /f E:\windows\system32\jscript.dll.
2. Type the following command, and then press ENTER to grant administrators full access to the file:icacls Path_And_File_Name /GRANT ADMINISTRATORS:FFor example, type icacls E:\windows\system32\jscript.dll /grant administrators:F.
3. Type the following command to replace the file with a known good copy of the file:Copy Path_And_File_Name_Of_Source_File Path_And_File_Name_Of_DestinationFor example, type copy E:\temp\jscript.dll E:\windows\system32\jscript.dll.---Some of the corrupted are repeated which only adds to my confusion.Here's the actual sfcdetails.txt document if it helps understand my situation.edit: Here's a text of just the corruptions.
The problem started when I had three updates that would not install at shutdown. I tried to run check disk and system file checker which neither would run initiallyCheck disk runs now and says there are no problems. SFC says "Window Resource Protection could not perform the requested operation." As for Windows update, I have tried deleting the temp update files located atC:\Windows\SoftwareDistribution\DataStore and \Windows\SoftwareDistribution\Download. I have also tried to Resource readiness tool as well as Microsoft Fix It for windows update. The fix it tool says it finds errors and fixes them but the problem is not fixed. It shows up every time I run the tool. Since deleting the temp files, windows update just says "Windows could not search for new updates" with and error code of 80070002.I suspected a virus at first but was unable to find anything with a full scan of AVG and Malware Bytes. Guess that doesn't mean there is not one.
I have this laptop with Windows 7 as the operating system and with a capacity of 500 GB. My HDD was making loud noises and weird noises so I brought it to the shop and they told me to change the HDD because it might die anytime. So I did a full backup on my external hard disk, meaning that I cloned my laptop. I changed my 500gb HDD with a 240gb SSD. And when I tried to restore my backup files into the new drive, there's an error: "no disk that can be used for recovering the system disk can be found".
So I did some research on the internet and found out the reason of the error: it's because the image created was from a bigger drive than the new drive I put into my laptop. Even though my backup files are only about 100gb, I still cant restore it to my 240gb SSD because the image created was from my 500gb HDD. I am going to copy my backup files into an external hardisk with a capacity of 200gb and then backup from that drive and then I will restore it into my 240gb SSD. Will the backup file be considered as a backup from the 200gb drive or from the original 500gb HDD?
i recently bought a new hard drive to put my os on, and i stupidly changed my old hard drive type from basic to dymainic, and its not letting me reformat it or convert it back to basic. When i try it says "Windows cannot format the system volume on this disk."
I have a toshiba with a windows 7 64bit, and it's been acting really slow recently and freezing up on me so I thought there might be viruses that I needed to get rid of, so I restarted my computer so I could go in safe mode with networking to check if there really were. When I restarted my computer I momentarily forgot to press the f8 key and the windows starting screen with the logo showed up. Without thinking I turned off my computer since I didn't want to restart again (it took forever for the computer to do). Once I turned the laptop on again I ended up going to system repair. For some reason this did nothing to my computer. I left it on for hours and hours until I finally decided I wasn't going to get any results. I once again restarted the laptop but this time when I went to system repair I cancelled it and when into more options and tried doing a system restore which also didn't work and said a bunch of my files couldn't be read. When I looked back at the system repair log it said "system volume on disk is corrupt." I googled it trying to find something to help me, and every place said to run sfc scan, which I did on command prompt, which always gave me the reply "there's a system repair pending which requires reboot to complete" and since my computer can't reboot properly no matter what this is what it'll say. Is there some way to run this scan or another way to fix my computer without having to lose all my data? I have some really important files on here. I've also tried running chkdsk /r /f in command prompt which it wouldn't let me do and said it can't lock the current drive because the type of file sytem is NTFS.
My computer shows Disk Volume Error every time I run system maintenance. I tried Chkdsk, disk cleanup and disk fragmentation, but it did not work. Also, my Local disk C is reporting only 8 GB of free memory. But in realty it has 17 GB free memory. Even I could not extend my disk volume through Disk Management.
I have a toshiba laptop running on windows 7. One day I turned it on and it said "bootmgr is missing press ctrl alt delete to restart."I have been researching how to fix it and have made a repair cd, which boots it and sends me to the start up process, but when I get to the command prompt option and type "bootrec/fixboot" it says "the volume does not contain a recognized file system."
I've just used Windows Update to install SP1 on two more or less identical computers with Windows 7 Home Premium 64-bit. On one of the computers only the following error and warning are showing in the event viewer, from around the time the actual installation started (ie immediately after the download completed):Error - Source VSS, Event ID 12305 Task Category None:Volume Shadow Copy Service error: Volume/disk not connected or not found. Error context: DeviceIoControl(\?GLOBALROOTDeviceHarddiskVolumeShadowCopy18 - 000000000.....). Operation:Processing PostFinalCommitSnapshotsContext: Execution Context: System Provider________Warning - Source Ntfs Event ID 57 Task Category (2)The system failed to flush data to the transaction log.Corruption may occur.(end of messages)Both messages showed exactly the same time. System restore shows that a restore point was created at the same time, which suggests that it did manage to create a restore point despite the error.I tried restarting the computer, and it didn't try to run chkdsk (which I would expect it to do if there were any disk errors, and which has been mentioned on other forums). Disk management shows all disks and partitions to be healthy (before and after the restart).
Here is a summary of my problem: 1) My computer recently got stuck on the "Starting Windows Screen." So I manually held the power button to reboot. 2) On reboot, it said there was a need to run a startup repair, which I did. Everything checked fine, except for the last one which said "System Volume on Disk is Corrupted," which it claimed to have successfully fixed. 3) After rebooting from repair, the system gets stuck on "Starting Windows Screen" for a good 10-15 minutes, after which it runs a registry check. After it completes that I get hopeful -- but the screen then gets stuck on an all black screen with just the mouse cursor and nothing more. 4) Additional note: Attempting to start the computer on "safe mode" leads safe mode startup to become stalled on "DRIVERSCLASSPNP.SYS" 5) The lastest attempt to repair yielded this message: "Startup repair cannot repair this computer automatically.

Disk checker was running and my laptop shut off midway through, since then my laptop hasn't been working because windows explorer is not responding. Safe mode works perfectly fine.What could be the problem and how should I resolve it?
I have been having a bit of trouble with windows 7 lately, namely that it won't start up right. When I boot from the drive normally, it gives me the classic "BOOT DISK ERROR: INSERT SYSTEM DISK AND PRESS ENTER" message.
However, I soon discovered that if I boot from the Windows 7 cd and do not boot from it (By ignoring the "Press a key to boot from CD or DVD..." Windows 7 boots up fine. I've tweaked my BIOS over and over, but the same problem persists. The drive is brand new and fine. What can I do?
System Wide spell checker? Does Win 7 have a system wide spell checker, something that will highlight all misspelled words with red underlining, then allow you to right-click on it to select the correct spelling? My win 7 was doing it for a while now it has stopped?
i recently got a computer from my aunt, and decided to put windows 7 on it. Before I installed it, I put in a Geforce 8800 graphics card and a (2nd) cd rom drive. After 20 failed attempts to install windows 7 (it kept freezing at the completing installation part) it worked after i disconnected the new graphics card and one of the hard drives. Now, however, i keep on getting periodic blue screens with the following error messages : Memory Management, and PFN_List Corrupt. I ran a memory diagnostic and it said that the memory is fine. What is wrong with my computer? I also ran a system repair thing from the windows 7 disk, and it came up with this error: System File Integrity Check and Repair Error Code 0X490
My Hardware is:
AMD Anthlon 64 x2 Dual Core Processor 6000+ 2 Hitachi HDT725032VLA SCSI 320 gb hard drives Nvidia Geforce 8800 GS Graphics Card 3gb of system memory
Less than a month ago I build a new rig, installed Windows 7 on my SSD and at a later time I attached my old 1TB large disk with still had XP installed on it.Windows is protecting this drive, all folders are flagged read only and I'm unable to remove the read only flag, each time I try, and check back after processing a job to un flag it, there still there.I'm able to delete files and folders after accepting the UAC popup, however, there are several folders I want to remove but am unable to, /Boot, /Documents & Settings, /Windows and some root system files, but windows doesn't let me.(I need to run programs with elevated rights in order to be able to modify those files) The /Boot is from an older Windows 7 install and it should be safe removing it, because I installed windows 7 on a SSD with out any other disks attached, so no dual boot stuff.But worst of all, many files are also flagged read only, along with my project files that I'm now unable to modify.What buttons do I need to press to get windows to understand he should not be protecting this disk and there ain't no windows installed on it so I can clean up get rid of those read only flags on the files
I have an external harddisk that is encrypted using TrueCrypt. Each time I plug it in Windows prompts me to format the disk because it doesn't have any recognizable file system. Vista didn't use to do this. I suppose it's because of the UAC changes and a user couldn't normally do this in Vista. How to disable this prompt in Windows 7?
I recently tried to install a mac osx on my computer that was currently running windows 7. I created a separate partition on my 320GB hard drive that was unallocated space until I partitioned it. After I installed it, when I tried booting into that hard drive, I got the non-system disk error. I went back into the mac osx install disk and erased the osx installation.
I then put in the windows 7 installation disk and clicked repair my system. It searched for startup errors and found that the Boot Manager was missing or corrupt. Is there any way I can reinstall the Boot Manager without reinstalling all of Windows 7? I ran the startup repair a few times until it could not find any problems. Now it says: Disk Error. Press any key to restart.
I have an HP Elitebook laptop. I got it new about 2 years ago and have had it attached to a docking station since I bought it. Connected to the docking station is an external hard drive where I store a complete backup of my laptop (I use the program "Norton Ghost"). I should probably also mention that the HP laptop used to have Windows Vista installed on it. I installed Windows 7 over it.
The Problem Recently when booting my computer I have noticed that I sometimes get a NTLDR or non-system disk error. Two things confuse me about this:
1) They only started within the last 4 months. I haven't changed anything.
2) They are random and don't always occur.
My attempts First off, here is my current boot order:
Notebook Hard Drive Notebook Upgrade Bay USB CD Rom USB Floppy External SATA USB Hard Drive Docking station upgrade bay ... some other stuff
Playing around with the boot order yields interesting results. If I change the order, the NTLDR error will disappear an the non-system disk error will appear and vice-versa.
Here are the drives I have on my computer: -Windows 7 installed on a 1TB drive -Windows XP on a 500gb drive -2TB drive for storage. -1TB drive for storage -500GB drive for storage
Windows 7 was installed before XP, and I believe XP came after the physical installation of the 2TB drive. I always have to press F8, and then select the first hard drive in the list, and then I'd be able to select to boot "Windows 7." Otherwise it'd give me "boot disk boot error, please insert system disk." The drive I'm selecting is my 2TB drive. My computer won't boot if the 2TB isn't plugged in. I've tried Option One and Two from here with no luck: [URL].

I just attempted to use Partition Wizard to repair my MBR after installing Ubuntu and having issues with a BSOD in Windows (0xC0000225).Now when I reboot all I get is "Non-System disk or disk error." I can't run fixmbr using a recovery disk because apparently that command no longer exists!
