Missing Operating System - RAID Drive - Show Up In BIOS

Nov 14, 2011

I'm working on a computer with a RAID setup. It is 2 hard drives 500gb each showing up as 1tb in windows. Both drives show up in the bios but all of a sudden when trying ot start the computer I get a "Operating system is missing" error.

I'm trying to run a chkdsk form a win 7 64 bit disk and telling it to run on H; (system drive) but it says 'cannot open volume for direct access'.

The other drive, C: is just a recovery drive built into dell computer systems. I tried using a boot cd and running mbrfix to no avail.

Missing Operating System, Del Key Does Not Work Going To Bios Setting

May 31, 2012

I was trying to recover/reinstall win 7 and bring back my asus laptop to its manufacture state. When I run the recovery media (recovery dvd) that comes with my asus laptop and after answering the prompts, it gives off "missing operating system" message on an entirely black screen. I tried to go to the bios setting by hitting delete key upon boot-up but it does not respond. I switched off and back on several times trying the delete key every time but to no avail. It's an ASUS N61J Series with intel i7.

Switch From Raid 0 To Single Drive With New Operating System?

Feb 13, 2012

We have two disks in raid 0. We want to get rid of them, as they are failing and install a single hard drive with Windows 7. We currently have Vista installed. There are no files I need to copy, just want to start with a fresh operating system. How do I go about this? Can I just remove the old hard drives and replace with the single hard drive and install Windows 7 on it, or is it more complicated than that?

Moving A Raid Installed Operating System?

May 18, 2011

So i would like to buy a whole new computer. but i want to keep the operating system which is windows 7 professional. It's installed on the hard drives as raid 5. now i know that the raid key or whatever it's called is stored int he bios so just plugging the hard drives into a motherboard that supports raid 5 won't work. So what can i do to install everything that i have on these hard drives into a new system? Also the operating system is registered online would i be able to re register it or something? i don't have the new computer yet i'm just looking around for something good and for a good deal.

Flash BIOS From Operating System?

Jun 12, 2012

Today, we can flash some BIOS from an operating system. Is this not quite dangerous, nutrient for viruses? When the OS is active, too many processes are active during this critical step and has a good chance something can go awry. I try to update always from the external usb floppy drive or from an usb stick.

Missing Operating System" Error Massage When System Starts?

Feb 18, 2012

"Missing operating system" massage is coming when i start my system and i am not able to start. I think because , i had given "mark partition as active" option for one hard dive (E) in disk management when last time i opened. it did not have any data. i did not know, this will make any problem. Now i am not able to boot windows re installation dvd also. i can only take BIOS settings.

Missing Operating System?

Nov 12, 2012

Have just registered to see if anyone has any ideas for a solution to a problem with my that is running Windows 7 (I think 64bit). It refuses to boot and just says "missing operating system".Using the repair option on a boot disc does not work (have tried 3 times)If I boot using a windows 7 cd/dvd I only get given the option to install windows.I can see both hard drives in the BIOS.I am able to get to a DOS prompt using the boot disc, but have no idea about DOS myself.When booting from the Windows 7 cd I was able to see the C: drive but it would not open, saying it needs formatting before use.I think that's about it, will post anything else relevant if I think of anything.

Missing Operating System?

Jun 19, 2012

I have a msi-gx680 laptop , I used my Recovery DVDs (which I had created mine by MSI RECOVERY software on my laptop) to restore my C drive to manufacture settings. When I insert the first DVD, recovery process would start but it goes half of the way and finishes, showing (Successfully Recovery!) but it doesn't need the second or third DVD, and when I restart my laptop the phrase "Missing Operating System" would appear.

Nov 12, 2012

I just shipped my computer out of the UK. One of the HHDs my OS was RAID 0ed to broke. Obviously I got a missing operating system error from that. So then I deleted the RAID volume and changed my boot 1st priority to my DVD drive so i could reinstall Windows on the hdd that's still alive at least.

Missing Operating System Windows 7?

Aug 29, 2010

I am getting the "Missing Operating System" message on boot. Here is the strange thing...if I change the boot order in the BIOS and have CDROM first and choose not to boot off of it Windows 7 loads fine. If I put HARDDISK first then I get the missing operating system message. I have tried running CHKDSK, BOOTREC and the plain old Windows repair util. None of them have worked.

Missing Operating System And Can't Boot From CD?

Oct 14, 2011

I've been using my new desktop for the last couple of months. Didn't have any problems until all of a sudden my computer just completely shut down and restarted while I was using it. And now it cannot boot, it just comes up with a 'Missing Operating System' message! I went into BIOS and it still detects my hard drive.

I booted from my Windows 7 CD and it looks like its going to load from my CD, and then it just stalls and comes up with the same message.. 'Missing Operating System'

Operating System Missing Error?

Jan 2, 2012

I get the "operating system missing_" error on power up of my lenovo ideacenter that is 4 weeks old. I have recently installed the net from Time-Warner on cable.. I called lenovo and the tech gave me the "press F2 while turning the power on to it". This works but why do I need to do this? What gives with it working and then it doesn't .... I have not moved, touched, jostled it or anything to it that I didn't do when it was first installed. It works fine but will this indicate a future of trouble? I have virus protection from McAfee is this not enough?

Feb 10, 2013

I have an Acer Aspire One that was running Windows 8 consumer preview. I wiped the hard drive and tried installing Windows 7 starter from a USB drive then from an external DVD drive.

Can't Boot Up Laptop, Operating System Missing?

Jul 11, 2011

So the other day I wake up to log on to my Alienware M17x m1, which was running windows 7 ultimate x64 sp1. As it's booting up, I see the message operating system missing. So I grab my USB thumb drive (my cd/DVD drive does not work, thus I have to use windows 7 on USB). Tried to reinstall windows that way, but was getting some partition error of some sort. Now when I try to boot up with USB, I can't even get to the windows 7 installation screen. I get - The Windows Boot Configuration Data file does not contain a valid OS entry.

Windows Won't Install - Missing Operating System

Jan 22, 2013

I built my computer a few months back, and it worked just fine. About three months ago, I got two 3TB and put them in RAID 0 along with my four SSDs (which were also in RAID 0). When I hooked up my hard drives, Windows stopped booting. It installs, but when it restarts to finish the installation it says "missing operating system." I tried reinstalling it in every way imaginable: With only one of the hard drives, no RAID, just one SSD, using the hard drive, using a USB dvd drive, etc.

the parts:
Cougar GX 1050W
Z77A-GD65
i7 3770K
GTX 680
32 GB RAM
4x 120GB SSDs in RAID 0
2x 3TB hard drives in RAID 0
LG 14x BluRay drive

Missing Operating System Message Cannot Reinstall Windows 7

Aug 29, 2010

Shut down PC last night, all working perfectly. Today it won't boot with the "missing operating system" message. Have booted from Windows 7 installation disc, tried startup recovery - took 2 hours before reporting no automatic fix possible. It cannot find an installed Windows OS to do a system restore, so I attempted a "custom" clean re-install. However, I then get a "canot create system partition or find existing one" error message. I have tried to create a "New" one but nothing doing. I don't seem to have any HDD drivers to point to either.

Windows 7 Installation: Missing Operating System After Using Imagex?

Oct 11, 2011

I'm an IT proffesional, currently going learning for my Configuring Windows 7.I used windows 7 since the first beta came out, and I must say, I never was dissapointed by it.But because I am learning I am trying to get all the computers here running windows 7, and I have a computer in my office wich I am trying to install it on.There are a few problems thoug:The computer only has a CDrom player, and cannot boot from a usb device.When I first got it, windows XP was installed, and it only had 750 mb of memory. Stupid as I was, I decided to give it a try anyway installing windows 7 from inside Windows XP using an external DVD player connected with USB.This failed, and gave me lots of error so I tried the next step.

As It cannot find a network share I had to instal windows PE on a CDrom and from there I could acces my extrernal HDD where I had a clean copy of windows 7 on as INSTALL.wim. I cleaned everything, and created everything from scratch with succes. Image X worked, and BCDboot worked. So it seemed to go great.After restarting my system, it still will only give me, Missing operating system.I tried to search on the internet but couldn't really find something related to my problem.In the bios it says I can start from IDE CD-rom device, Diskette drive, Hard-Disk Drive c:, Integrated NIC (Disabled)I bought some different memory and I am now at 1.5 mb DDRIt is an Intel Pentium 4 processor 2.4 Ghz Level Cachge 512 Integrated.It's a DELL Optiplex Gx260 Series.

The boot menu gives me:. Normal2. Hard-Disk Drive C: (Wich I used for my 100mb) (And I used D for my big partition and with BCDboot I used D:WindowsSystem32cdboot d:windows /s D: ) Wich worked because he did copy the files.

Boot MGR Missing, No Operating System, BSOD While Trying To Download?

Jun 19, 2012

It all started when I realized I downloaded the 32 bit operating system on my desktop. Now however, I got a BSOD when I inserted the CD into the desktop. People around the internet said that you must go ahead and format the drive, So, I went ahead and did that. Thus deleting the operating system in the process. Now, When I try downloading the operating system, I get this message:Boot MGR is missing. restart the computer.I have tried everything. Using my laptop to make a USB Drive to boot it up. I cannot do that because my laptop is a 32 bit operating system, and I want a 64 bit.Please, The motherboard is a M5A 78L-M LX Plus with an AMD chipset. The monitors work fine and everything works until the boot MGR Pops up. I am puzzled because while working on computers in school, this only popped up when the operating system was on the harddrive. However, I cannot do anything at all.

Overclocking Process - Missing Operating System Error

Feb 1, 2013

Ok, so in the process of overclocking, I rebooted my computer and then got the "Missing operating system" error. I reset the CMOS and that didn't work, in the process of trying to boot from my Windows 7 disk/Linux distro's so I can see if one of my drives crashed but nothing seems to want to boot, so I am at a loss. Also, it seems in the BIOS, some of my SATA devices aren't being recognized. That may be because I reset the CMOS but I'm not positive. I can only see one of my SSD's in the BIOS and one of my optical drives.

Specs:
i5 2500k
MSI Z77-GD55
XFX DD 6870
12GB of G.Skill Ripjaws red/blue (2 x 4GB) & (2 x 2GB)
Corsair Force 3 60GB boot drive (Raid 5 with OCZA3 60GB)
OCZ Agility 3 60GB boot drive (RAID 5 with CF3 60GB)
WD 1TB Caviar Black storage
Corsair TX850M

Dell Inspiron Won't Start Missing Operating System Error?

Aug 8, 2012

Using the Windows 7 DVD that came with the machine I went through the repair Windows procedure 3 times. The first time it searched for restore points of which there are none because the machine has Rollback Rx installed instead. It then restarted with no change. I went through the same process but this time it said it had repaired Windows however; restarting gave me the same missing OS message. On the 3rd attempt it displayed the restored OS as being on D:. I ran the diagnostic tool and it said no errors were found. Restarting gave the same error.

Operating System Restore With Disc, Missing Drivers/software?

Sep 27, 2012

I was trying to completely restore my system using factory discs. I upgraded my ProBook 4525s from 32 to 64 bit. because of all the problems I've been having, I tried putting on the 32 bit version again... well somehow I'm miss a whole lot of stuff. I'm not super computer savy, but figured that i've bdone it in the past, I can do it again. Well the first thing I noticed is that my wireless isn't working. So I go to HP website and try and download some different drivers. Nothing is working and when I try to open and install anything downloaded it doesn't work properly. Went to update my bios and it needs F.0A which I can't download because I don't have a burning software that is compatible. Why I need to burn something to disc when I want to download it directly I don't understand..
