Windows Failed To Start: Bootmbr Missing
Jun 18, 2008
I boot up my computer today and up pops a message about my bootmbr being missing. I, figuring this was quite bad, stuck in the ol' vista installation disk to run a startup repair. It does its thing, says its successful and tells me to reboot. I do, and get a new message at startup, saying,"Windows failed to start. A recent hardware or software change might be the cause...
File: Windowssystem32
tkrnlpa.exe
Status: 0xc0000428
Info: Windows cannot verify the digital signature of this file"
So I figure I'm getting somewhere, load the disk repair, and I get "Startup repair could not repair the problem." along with other steps i should take to "send it to microsoft"() So now i run commands like chkdsk /p,bootmbr,bootfix (I've done this before). NONE of these do a darn thing to solve my problem. (Ive done the F8 thing with the load drivers w/o signatures; didnt work.) So, I figure i should take matters into my own hands. So i open up a CMD, and copy a ntkrnlpa.exe from my install disk and replace it with the one on my hard drive. Logical? I thought so. But same results. Except for one thing, when the repair thing runs again, the details say that the file "pshed.dll" is corrupt. I replace this one, doesnt work, and then says the ntoskrnl.exe is corrupt too.... I replace this one as well, but this one has remained corrupt. I sometimes get a new message when running the startup repair. System volume on disk is corrupt. But other times I get "Boot status indicates that the OS booted successfully." So Ive pretty much used all I can think of, short of booting BartPE and copying my important files and reinstalling. One more thing that happened. Last night (when everything was running smoothly) diskeeper did a boot time defrag. I think something went wrong and this is what is causing all this trouble.

My computer was working properly,then I had a power problem, my computer turned off and turned on again.Now my windows doesn't open. When I try to open I receive this message: Windows failed to start. File:windowssystem32configsystem Status:0xc000014c Info: Windows failed to load because the system registry file is missing or corrupted.
Need to fix it without losing my files.I have a restore cd, but I dont want to use it, because I can't lose my files.The cd doesnt has the choice to repair windows.Just restore it. I am using Windows vista premium and my computer is Aspire E380 (Acer) It has C: and D: partition, but I dont know if it is 32 or 64 I already use all steps in F8 screen, safe mode....last configuration...anything didn't work.

I have been having serious difficulty getting my laptop to start in the last few months but have usually been able to solve the problems for a while until they come back but now I am faced with a new boot issue that I cannot fix.
When I turn on the laptop, after about 5 minutes I get the message "windows failed to start because the system registry file is missing or corrupt" and gives this location windowssystem32configsystem and also status: oxc000000f. I am instructed to boot from the vista dvd and repair windows, startup problems or whatever but when I try this I get the exact same message described above.
I have had a lot of startup problems recently but they have always been solved either by booting from the dvd and reparing startup problems, or more commonly, by running the chkdisk which would generally have my laptop running well for a week or so before new problems occurred. I've searched the web but people keep suggesting booting from the vista dvd which as I said isnt working. No matter what I try I get the same message, safe mode etc will also not work.

I have the Home Premium edition and recently I received the following error:
File: WindowsSystem32tkrnlpa.exe
Status: 0xc0000001
Info: Windows Failed To Load Because The Kernel Is Missing, Or Corrupt
It tells me to insert my installation disc and restart your computer however when I do that I go right back to the previous screen which I just described. I already changed the boot order to boot from the DVD drive first however it continues to skip this screen and keeps looping to the same screen. Does anyone know another way to load my disc so I can continue with the repair?.

I have a dell 1525 running vista home premium 32bit. Just a few minutes ago I was transfering music from my hard drive to my external hard drive, while on the internet looking at videos. I noticed that the file transfer process was taking a while so i decided to cancel the process. Some error message popped up after a while, being stupid I didn't write them down and kept watching my videos. My desktop disappeared and i cou;dn't start task manager so i decided to restart my computer... When I restarted I was greeted with "Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart the computer.
2. Choose your language settings and click next.
3. Click "repair your computer"
It also gives me the following options:
4. Safe Mode
5. Safe Mode with networking
6. Safe Mode with Command Prompt
7. Last known good configuration
8. Start Windows normally
When I restart booting from the reinstall dvd from dell and i get to the repair my computer part, vista isn't listed in the options to repair. And I can't browse my main hard drive. Also when I start into safe mode, all the driver load then I get a quick flash of a blue screen which says(i video tapped it then slowed it down to read the message): A problem has been detected and windows[COLOR=#05408F ! important][COLOR=#05408F ! important][/COLOR][/COLOR] has been shut down to prevent damage to your computer.........

My laptop (Advent 8117 running Vista if that helps) has been working fine, then this morning things went pear-shaped. To begin with things worked as usual - Everything seemed to load up as normal, I left the room for maybe 5-10 minutes and when I returned there was a black screen. I waited a while and nothing happened so I restarted. It comes up with 'Windows failed to start. A recent hardware or software change might be the cause.' From there I can either start normally or run a repair. It doesn't seem to matter what I click here because I get a 'Techguys' support thing come up either way but now nothing on it works. To begin with I ran the Repair Environment, but it couldn't fix it. I also got to try a System Restore but I seem to have no points to restore to. Now I can't get the Techguys page to do anything. So I tried running in Safe Mode but once again I'm faced with the unmoving Techguys page, and the same goes for when I try and load from the Last Know Good Configuration. I desperatly don't want to have to lose everything.

I am building a brand new system and bit the bullet and am attempting to install Vista Ultimate 64 with SP1 (Brand Spanking New DVD with SP1 on it). Everything boots up just fine, memory is okay (4 Gb), install runs fine and after the reboot, I get the following: File: Windowssystem32toskrnl.exe
Status: 0xc00000e9
Info: Windows failed to load because the kernel is missing, or corrupt. (I purchased all parts and software from Newegg) When I go to the MS Support site and put in the Product Key, it tells me that it's in an invalid format. 5 - 5 - 5 - etc is what I have, however, Microsoft is wanting 5 - 3 - 5 -etc. format. I have pulled out EVERYTHING and disconnected EVERYTHING except the DVD, HD, and vid card, so I'm running it as barebones as I can.

I'm currently having some serious problems with my main desktop pc Q6600, 4gb Ram, Vista 64 Ultimate where when I turn the machine on I get a message saying: 'Windows failed to start, A recent hardware or software change might be the cause File: WindowsSysWOW64DriversPxHelp20.sys Status 0x0000359 info: Failed to load because a critical system driver is missing or corrupt.' This problem started after I ran windows update a few days ago. its asked me to try putting the vista dvd in and run a repair, but that failed miserably. other things I would like to point out is that I am running a Raid (Stripe) on my system drive, so I cannot just take the discs out to recover the data. Is there anyway I can solve this issue whilst keeping the operating system intact? finally i'm running the OEM version of vista....I'm feeling pretty fed up as most of my important data is on these drives and ironically I was going to purchase a larger backup disc this month when I get paid.....

I lost power to my home and my battery backup gave out before I got home to safely shutdown (I don’t normally lose power long enough to wipe out my backup). When power came back on I rebooted Vista 32Bit and was able to login but there were errors (which I did not record). Vista informed me there were errors and suggested I reboot and run CHKDSK. I tried to run chkdsk next time windows load but after my bios loaded I had nothing but a Black screen. I waited for 8 hours and still black screen. So I booted from my Factory Dell CD and Vista was unable to repair automatically.
Boot critical file C:Windowssystem32driversWdf0100.sys is corrupt
Boot critical file C:WDFLDR.SYS is corrupt.

2. Choose your language settings, and then click "next"

File: BootBCD
Status: 0xc000000f
Info: An error occured while attempting to read the boot configuration data.
problem I have is that I do not have vista installation dvd. I am currently studying abroad in Rome and will take more time than I have to receive the dvd in the mail. None of my friends here have one either, but they all have the same make and model computer that I do. Is it possible for one of them create a installation dvd that I could use? Or could they make a recovery disc that could as least get me to the system recovery options screen?

On my laptop I triple boot: Windows Vista Home Premium 32-bit, Windows XP Professional 32-bit and Ubuntu 8.10 64-bit. Recently, I had problems booting WIndows XP so I wanted to fix it by using VistaBootPRO but I ended by losing both WIndows Vista & XP. Now, only Ubuntu works so I can still access Vista & XP drives. On VistaBootPRO I installed Legancy Bootloader over Windows Vista Bootloader then I was not able to boot Vista. I got this error message:
Code: Windows could not start because the following file is missing or corrupted: <WIndows root>system32 toskrnl.exe Please re-install a copy of the above file.

when i turn on my computer, an error message comes saying "Windows failed to load because a file is missing or corrupt File: Netio.sys Status: 0xc0000221" This started when i was clearing my computer of useless programs, and after i deleted Realtime player or Quicktime player, (can't remember which) an error message jumped from the taskbar saying something about Network device driver. After that every time i start the computer, the "Windows failed to load" message pops up. The first half a year, it was solved by pressing enter, to "Choose an operating system to start: Windows Vista" and then to "Windows error recovery (start windows normally, safe mode etc)" and back to "Windows failed to start", repeating it 3-20 times. Then i had a familiar "Unexpected shutdown" during a game, and now, the "Enter spamming technique" doesn't work anymore. All i can access at the moment is Windows memory diagnostic tool, and Bios setup utility. Is there any way to fix this through the setup utility or some other manner?

When I switch my laptop on, I get the following message: "WINDOWS FAILED TO START. A RECENT HARDWARE OR SOFTWARE CHANGE MIGHT BE THE CAUSE...". I then have the option to launch system repair or start windows normally. Either choice I make has the same consequences...a screen launches saying "loading windows files" Then I am taken to windows loading screen with little green bar. Then the screen goes black. Not off, just black. If I try and do a system recovery, I go through the same steps via f11 but then I get the 'blue screen'. I didn't create the boot disks that one is supposed to do when they get vista.

I have just built my first computer. My whole family is a mac family but i have always found vista easy to use on my friends computers. I bought Microsoft Windows Vista Home Premium SP1 64-bit for System Builders - OEM from newegg. Now when i boot from The disc it says "Loading windows file...." and once it is done with that an error appears saying. "Windows failed to start. a Recent hardware or software change might be the cause, to fix this problem....."
It gives me ways to fix it but all of them require some OS to be on the computer and i have none.. It also says: File: windowssystem32ootwinload.exe......

When I tried to make a backup I've got an error message saying:
Backup failed
0*80070017 cyclic redundancy control failed
I've searched the net for that code and they suggested chkdsk, I've done that and ran sfc/scannow with elevated privileges. Sfc did correct some problems but there is one problem he could not repair. I've looked at the log in c:windowslogscbs and searched with the tag [SR] to narrow down, and there was a problem that occured several times.
Windows SIdebar settings.ini is corrupt or missing (64-32bit program files) and when sfc tries to look for backup of the source file it also stated that this one is corrupted. So I was wondering I've someone knows a method to correct this? Maybe if there is a way to reinstall the sidebar my problem could be solved (?) I can't use System restore because I recently deleted those checkpoints, because of an space lack on that partition.

My elderly Mother's Vista PC isn't working, and as she relies on this for shopping etc I need to get it working (I am several hundred miles from her). The PC tried to install the latest Vista updates (20/2/2008) but upon restart she gets the message "Windows failed to restart - a recent hardware/software change may be the cause - File windowssystem32winload.exe "The selected file could not be loaded". She doesn't have a start in "normal mode" option. I have walked her through trying system repair/restore using the Vista installation Cd, but after trying to restore she gets the message; "system restore failed due to an unspecified error; "cannot create a file when that file already exists" (0x800700b7) We have tried 3 different restore points with the same result.

I have a HP laptop with Windows vista home edition, and this has never happened to me. It started today, in which I thought it was nothing. I'm a little worried to be honest and I don't know what's wrong with my connection. I can access the internet on my mother computer which is a desktop, yet I can't on my HP laptop. it says "The Dependency Service or Group Failed to Start"?

I just bought and installed Vista Home Premium x64, I've been running it for a few days now and I quite like it. I've had no issues with hardware and drivers. Although, two things that don't sit well with me are the start menu and the disk defragger. The start menu, in particular games, is messy and inconsistant. Games are placed in the games folder/menu and that would be fine if it did it for all games but it only puts some games there. Secondly, if a game is in the games folder, it never appears in the recently used list in the start menu. This I don't like at all. It means that the recently used list pretty much all windows programs that I rarely use. Some games are in the games folder only, some are in the games folder and the all programs list and some are in the all programs list and recently used list but not in the games folder...? Also if you delete a desktop shortcut the icon in the recently used list doesn't work as it is pointing at the desktop shortcut that is not longer there instead of the actual executable.
I feel that the start menu in Vista has been ruined in an attempt to make it more sophisticated than that of Xp. In general though, Vista IS more sophisticated and does make using windows better and easier but being that the start menu is such an integral part of day to day use, it's really something that shouldn't have failed. The defragger: i'm trying to understand how this thing works if it works at all. Very confusing! If you manually start it, the defrag process never ends and yet if you kill it after hours and hours then run a 3rd party defragger it will say that the drive is still fragmented. If it's a low level background process why doesn't it just run all the time with no gui? Anyway, apart from thsoe two mind boggling things, I really like Vista - It looks cool.

Recently i installed Vista x64 Ultimate and as i remember in startall programs there are two icons of internet explorer (32 and 64 bit) and WMP icon. Now that icons are gone. Is that because Opera is my default browser and Gom and winamp are default media players? Of course i think that this is not problem. I remeber that i deleted that icons from quick lunch but deleting them from quick lunch doesn't mean deleting tham from start menu, right? Wmp and IE can be started directly by typing wmplayer and iexplore in search but i want that icons back in startall programs!

I recently had to reinstall Vista Windows and had to copy some of my program files across from the 'Old Windows' program file to the new Windows program file and they are now not all showing in the Start - All Programs menu or in the Programs and Features 'Uninstall or Change a program' list. How can I get all my programs into these two locations?
