Windows 7 Won't Boot After Defrag
Aug 19, 2012
I normally dual-boot Windows XP and Windows 7 from separate partitions on the same physical drive. Now I cannot get Windows 7 Professional to boot after defragmenting the volume on which it resides from a different OS (Windows XP). Upon selecting Win7 from my boot menu, it initially gave a bootmgr error that a critical file could not be found.
I booted from the Win7 DVD and selected to repair my Win7 installation. I clicked on the details and the log indicated that partmgr.sys was found to be corrupt and had been replaced. Upon restarting, the Win7 animated logo appeared, but after that the screen went black and the computer rebooted.
I confirmed that partmgr.sys was replaced by booting into XP and looking for the file on the Win7 partition. I ran startup repair from the DVD again, but it said it replaced the same file- partmgr.sys - again. Chkdsk comes up clean, and the sfc /scannow command won't run because "there is a repair operation schedules that requires a reboot ."
There has got to be a way to get back into Win7 given that all I did was defrag..

Auslogic's Disk Defrag is a free utility. how it compares to Win 7's built in defrag utility? Is it worth downloading over what's already there?

How do I turn on and off Windows 7 defrag and optimization at boot time? Is there an option for periodicity? I don´t want to let HDD running at 100 pct for hours. How do you choose optimization of the system files too? And can I run it not only on drive C:?

So I have defragged my system multiple times to optimize my overall system performance and every single time it shows 1% defragmented, eventhough I have ran the built in defragger for windows 7 64-bit home premium x amount of times to fix this.
I know that its not an immediate concern, but is this something I should be concerned with, since something seems to be wrong during file allocations when defragging.

I cannot get windows defrag to work on a schedule. It works if I do it manually but not on schedule. I like to use built in Windows defrag because it does not delete system restore points but 3rd party software defrag deletes restore points.

Is the Windows defrag running in idle? I think it is a new feature since Vista right? I have checked it and my sytem drive is 16% fragmented. I have waited with performance monitor on for an half hour and there where no harddisk access from defrag?

Windows home Premium, tried safe mode and administator mode. No go. The button will "push in" with the cursor but nothing happens. I have it set to run automatically under Task Scheduler once a week. The system runs ok, but .I can't tell if it has run, or when it quit running, and sooner or later it's going to need it. Somebody told me if defrag doesn't run, that isn't the only thing that's broken.

HP Pavilion laptop purchased in June 2011 - still under a 2 year warranty, but would prefer to resolve this myself if at all possible.In the last few days I've started experiencing some BSOD issues, which got particularly acute late night...constant BSODing as well as just system freeze ups. I ran Avast antivirus scan, as well as a MalwareBytes scan and the Housecall scan. I used CCleaner, downloaded what windows updates my computer said were available. Was going to try to defrag but it crashed again. On a netbook right now.this is the BSOD error I get:---kernal_data_inpage_error***STOP: 0x0000007A (0x0000000000000020, 0xFFFFFFFFC000009D, 0xFFFFFA8006E0F078, 0x0000000000000000)Physical memory dumpy FAILED with status 0xC000009CI have no idea what that means - not super troubleshooting saavy beyond the basics

I read an article titled "Windows 7 gets SSD-friendly" a while back that Windows 7 was supposed to take more consideration regarding computers with Solid State Drives. One of the mentioned steps would be to disable the Defrag option (something to do with SSD not getting any benefit from the defraged drives yet the extra work could actually lower the lifecycle of the SSD).Quote: At last week�s WinHEC techfest, Microsoft announced it wanted Windows 7 to make better use of SSDs. �SSDs are on the path to reach their full potential� says Microsoft senior program manager Frank Shu, who in a conference session on Windows 7 Enhancements for Solid-State Drives outlined how Windows 7 will be more SSD-friendly than Vista or XP. After recently installing Windows 7 onto my Lenovo x300 (which includes a SSD) I noticed the Defrag schedule was not disabled.

The defrag tool in Windows Vista and Windows 7 seems to skip fragments larger than 64MB in size in order to cut down on defrag times.This problem was easily "solved" by going into command prompt and using the "-w" parameter.Example: defrag c: -w This option seems to have disappeared in Windows 7, and as such, large fragments are left unoptimized.

when i try to run my disk defrag it says "Disk defragmenter cannnot start because the task scheduler service is not running. Start the task scheduler service and try again" I tried to open the task scheduler but that isnt working. When i open the task scheduler it says "The remote computer is not found." If anyone knows what i can do i would appreciate it.

Is there a way to clear the 'Last Run' date and % fragmented in Disk Defragmenter in Windows 7?I've cleared the event viewer application and system log files and also completely disabled and reenabled the defrag service. I'm not sure what else to try.I ran Analyze on my SSD (did not run defrag) to see what it would say. I just don't want that history showing it as fragmented. I understand it's a trivial complaint though, but don't like seeing it. That data has got to be saved somewhere in the OS and I want to blow it up

Whenever I try to do a scan either with McAfee or Windows Defender.. And even disk defrag. it freezes the computer
I hear a noise which i think is from the hard drive.. it sound like.. Tick, tick, tick, tick.
And when it does that I am not able to open any programs and the scan stops. But i am able to move the mouse and open the start menu.
Any Ideas?

i've been doing some movie making for Internet lately, the raw avi files for which are rather large, the latest being 7.5gb for not even an hour's recording. are these files weaving around the smaller ones the reason for my hard drive getting fragmented so much lately? i just ran an auslogics disk defrag analysis and it found my hard drive was 11% fragged, and windows defragmentation found 14% the other day.

My laptop (Dell Studio 1550, Windows 7 Home Premium 64 bit) just gave me the black screen upon start-up. The Iolo System Mechanic had defragged the registry, I think, and it seems that the process had damaged my laptop's registry. I've ran sfc /scannow with no issues, but the memory diagnostic test froze. I am now running System Restore but it too returns a black screen upon completion.It seems from prior threads that a clean re-install is necessary. Would like to know if this is indeed the only solution, and if so, how do I go about re-installing without an installation CD (Dell never sent one, and I had bought the laptop abroad while I was in college).

Disk defrag will analyze the disc but when I try to defrag at the point the process reaches "PASS 1, 2% REALOCATED" the process stops, neither the mouse or touch pad will work. This has been happening a for some time now. I have cleaned out programs not used anymore, etc. I am using 116gb and have 174 gb free / 32 bit operating system, 3gb ram, windows home 7 premium, service pack 1.

I have a two HDD setup with a newer Western Digital Caviar Black 500GB as my secondary drive. It stores all my bigger files such as video games, videos, and so on. Whenever I try to optimize that hard drive using Disk Cleanup or Disk Defragmenter, it doesn't seem to execute the program. The hard drive is running and DC and DD have it on their list but when I use DC it would just come up with 0 mb to clean every time and DD always run a lot faster than the smaller primary drive which is also Western Digital. Is there somewhere in Windows 7 configuration that I need to change to enable the disk to be optimized?
