"ntoskrnl.exe Is Missing Or Corrupt"appears Unless Disk Is Inserted
Jan 17, 2013
When I installed Windows 7 Pro x64 today, I did a custom install but I didn't format my drive beforehand. After it restarted the first time, it came up to a screen that said this: Code: Windows could not start because the following file is missing or corrupt:< Windows root>system32toskrnl.exe.Please re-install a copy of the above file After several failed attempts my Dad somhow got it to install properly, and it worked fine until I needed to reinstall updates. When it restarted again, the same screen came up. I put in the Windows 7 DVD and restarted, this time it booted without any problems. My boot is setup as "Boot from CD/DVD Drive" first, and "Boot from HDD" second. But when it said "Press any key to boot CD/DVD" I didn't press anything, and it just moved on normally.

after installing Windows 7 64bit, I start suffering from the next message:
windows 7 could not start because the following file is missing or corrupt: <Windows root>system32
toskrnl.exe
This issue continue occuring even after I tried several repairs of the OS. The strange thing is that only happen if remove the original disk from the DVD reader. If I leave the cd, the error does not occurred and the windows reboot normally.

have a Toshiba Satellite A505-S6980 Windows 7 Home Edition Premium Edition laptop. I recently tried to dual boot with Windows XP Professional service pack 3 iso cd. I partitioned my primary windows 7 drive and installed the windows xp on the smaller partition. The windows xp was working fine then I downloaded easybcd and tried to add XP to my OS choices menu, while logged on my XP partition, and then each time I try to load XP from now on I get a blank screen that says Windows could not start because the following file is missing or corrupt: [CODE]

Recently installed Windows 7 64 bit on my main hdd (had previously had it installed as 32 bit). Now my back-up drive gives me this error. The back up drive does not have windows installed on it, and is not a boot drive. But when it is connected I get this message: "Windows root system32 ntoskrnl exe missing or corrupt." In order to boot on my main drive, I have to disconnect the back up drive.
I don't understand where to reinstall the missing file - if I put it in the Windows 7 files, won't that mess up my main drive?

I recently upgraded from WinXP x32 to Win7 Ultimate x64 and kept getting the:"Windows rootsystem32 toskrnl.exe is missing or corrupt" when attempting to boot.
My system:
CPU: Core2 Quad Q8300
Hard Drives:
Primary (System) = Western Digital 300GB 10,000rpm
Secondary (Data) = Western Digital 1T-GB 7,200rpm
*External cloned CasperXP backups for BOTH on matching HDs -- However the backup Sys HD is still configured w/WinXP x32 until I can get all problems ironed out.
Problem Discovered:Upon booting the OS is pointing to the Secondary HD as Primary,however, once booted the C: drive is indeed the intended 300GB and Secondary is the 1T-GB HD.
How Discovered:I needed to relaunch the OLD XP system to access some old Firefox Bookmarks so replaced Sys HDs. Had to reconfigure boot sequence to get OLD x32 OS HD to boot (successful). Saved Bookmarks and shut down. Replaced the Old x32 Sys HD with the New x64 Win7 OS HD. Then got the above error repeatedly. Played with boot settings and BIOS settings for an hour before identifying that the x64 Win7 OS would ONLY boot with the Secondary Data HD listed as the Primary Boot Device. Do note that the OS files are all on the 300GB Primary even as the boot sequence points to the secondary HD.
QUESTION:Is it possible to correct this situation WITHOUT having to do a clean install of Win7 x64 with the 1T-GB Secondary Data Drive disconnected, in other words doing a clean install with ONLY the 300GB Primary connected?

I am having problems with autoplay, it doesn't open when I insert a disc. I get a message that tells me that I don't have a program installed as default when opening a dvd, same with audio discs but I have media player. I can still explore and install programs and have found i can open DVDs with Power DVD but I would like to find out why DVDs and CDs just don't open. I have autoplay ticked in default autoplay settings and have attached the message I get when I try to open from my computer.

I'm not particularly computer literate, however my desktop computer won't read discs. Whether it be a DVD, a set-up disc or even music CD's, there's a 1 in 10 chance that it will see it is there. On the odd occasion it opens, it works fine.
Currently an issue as I am trying to install wireless stick software but the disc will not load.

I recently installed windows 7 on my dell xps m1530 laptop. Till yesterday, the dvd drive was working perfectly fine, but yesterday, it just suddenly started ejecting all the cd/dvd i inserted. I tried using Microsoft trouble shooting, and when I chose that I was having a problem in playing the dvd, it started scanning for errors, and i inserted a dvd during it, it started working. But when the program ended, it found no problems. After closing the program, I inserted another dvd, and the same problem. The dvd drive is TEAC DVD+-RW DVW28SLC. I have tried reinstalling the firmware using device manager but it doesn't work.

I know this doesn't really give much away to my problem but i'm just as confused.
My laptop has recently started making the little beep noise that would occur when inserting a usb device etc. but i haven't inserted anything into the laptop at all?
I have checked various windows device programs but to no avail, there are no yellow triangles in the device manager, so i'm unsure as to what has caused this?
I have also system restored but it still proceeds to make the noise.

I'd like an icon to show up on the taskbar whenever I insert a USB thumbdrive. Then I can click this icon to safely eject the USB. I'm not talking about the notification area. I'm talking about the taskbar where open programs show their respective icons.

Every time I stick a DVD (game/movie) into the drive it comes up with an autoplay box with 1 option, to open the folder to view files. In Explorer the DVD shows up just as a generic DVD - basically as if it were just a blank disc for burning. If I 'explore' the disc there are no playable files, just an empty folder and a notepad document. I can't play the DVD in WMP, or any other player and can't start a game from the disc. This happened once before after burning a CD, the system just wouldn't recognise DVDs. It sorted itself out pretty quickly last time, this time, again after burning a CD, I can't get it to work.

Would you know how to get my disk drive to start showing up and reading disk again? It stopped when I installed Windows 7.
I am guessing the Optiarc DVD is it. I went into properties and looked at its status and it gave me "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

I tried to break the disk on several parts with Partition Manager, but at the middle of the process it froze and I forced the computer to restart. After resetting it says to "Insert the Recover Disk or other Recovery Media". After it I put the disc with the Windows 7 and at the menu where you have to choose to move (by keyboard arrows) to installation, the keyboard does not work, so I can't move to the installation and it jumps directly to the Local Disc. I also tried Windows XP disc and the same problem - there is no chance to reinstall the system. The keyboard is working in the BIOS, but after does not work.

I have just installed Windows 7 Home Premium on an HP Pavillion a1629.uk, and the second internal drive is sometimes not present on booting up. The failure rate is about one time in ten. Originally the machine had C: and D: drives with XP installed on C:. The original C: drive was discarded, and a clean installation of Windows 7 was made on on a new 500 GB disk. The original D: 500 GB drive (Seagate ST3500320AS) was left in place, but as stated is sometimes not detected. The drive is always present in the BIOS, before windows boots. On the occasions that it is not detected in Windows 7

Well I have been trying to fix this error for hours And after the system recovery scan it says there are problems with my start up options but I cant hit those buttons because the s2 keyboard I have in simply wont let me. Secondly I have ran the repair tool but it says I have to manually fix this problem so I tried using the command prompt but to my great luck again I cant get to that option because of my keyboard so I think the real question here is what do I have to do to my keyboard to land over all of the settings?

Yesterday i was trying to detect my external HDD on my pc. So I opened diskmanager through diskmgmt.msc, then on the external drive I right clicked and chose enable "something"( my os is not english so i don't know the exact word) but the thing i should have done was just to give it a path. Then i also right clicked on one my C drive (btw my C is drive is partioned for some reason, 100 mb and rest) and did the same "enable" thing to it, too. Now when I try to boot my pc, it says BootMgr is missing. Now I cannot format because there were telabytes of information on my hardrivers regarding my projects and I also don't have windows 7 cd.I have been trying to boot from SSD in BIOS but no luck.windows 7 Professional 64 bitIntel i7 26004xKingston 4 gb 30 gb SSD2 tb HDDATI RADEON HD 6970

In my Sister's laptop, running Windows 7 Ultimate x86, all of a sudden, while she was working on the computer, the "E drive" went missing which was a partition on the hard disk (I don't remember if it was a logical or primary partition). She tried restarting the system but to no avail. So, I told her to open the "Disk management" tool in Windows 7 to see if the partition is visible in there. I did this because sometimes, in my computer, my expansion drive wouldn't show but it would be visible in the disk management tool and all I had to do was to re-assign it a drive letter. But, in this case, it wasn't visible over there.
So, now I told her to download "Mini-Tool Partition manager Home edition" and install it on her laptop. On running it, it wouldn't show the partition either. It would just show "C:", "D", "System Reserved" and unallocated space. However, when I added up the size displayed by C:, D:, System Reserved and Unallocated, it doesn't add up to the actual hard disk size. It means the partition is somewhere there but not visible. Is it possible that the partition would show up correctly if the laptop is booted into the bootable image of Mini-Tool Partition Manager?

I bought a Samsung RF711 with Windows 7 and Microsoft Office Starter 2010 in June 2012. I had to reinstall the system from the DVD. While Windows 7 is up and running, there seems to be no installation files for Microsoft Office Starter 2010.The Samsung support website for this computer does not offer an Office download

I have a 1TB hard drive partitions into a C drive and D drive. The operating system is Windows 7 64 bit. The C drive is my every day stuff, and I use D to store media, music, video etc. Today I wanted to access the D drive and it was not there. The C drive is listed as usual. I went to Disk Management and the missing D drive was not there as well. I don't know if this explains things, but I ran a partition analysis program and it showed 500 gigs as unallocated. But that space is also not noted in disk management. Right now I am running partition recovery software to see if the files are somewhere, but it will take a few hours.

Yesterday evening I was having computer problems so I decided to do a clean reinstall of WIndows 7. I cleaned out some partitions and then tried to put WIndows 7 on the fresh partition. The process began and then I got a mesage saying that Windows cold not format a partition on disk 0. This error occured while preparing the partition selected for installtin. Error code 0x80070057I also get a message when I restart the computer saying ¨Missing Operaing system¨ I´m guessing that that means I cant log in to fix this problem

my sister has Sony Vaio E-Series which runs windows 7 Home edition. She encountered a problem starting up the windows and decided to use Recovery Disk, Recovery Disk stopped working and needs additional source (disk) to run. She weren't successful so decided to stop recovery and run it again. After that the error "BOOTMGR is missing" appeared! When I put the recovery disk inside the machine it doesn't work. F8 and F4 keys also don't work. So I can't use the similar solution mentioned on the internet like running "system restore". She also doesn�t have Windows 7 installation disc to run.
