If you have a Vista installation disk you can boot to the cd drive and use the recovery tools on the disk. If not you can download a Vista recovery disk here.

Are you able to boot to safe mode by pressing f8 during the boot process?
A system restore may be able to do the trick, else a windows repair maybe.

I turned on my Lenovo desktop and the 'missing operating system' message
appeared. I have had no previous problems. What can I do?

A:missing operating system (vista)

It normally indicates your HDD is caput. You could look in the BIOS to see if the HDD is recognised.
If you are out of warranty you could open the PC case and clean out any dust and then remove and replace the HDD.
If that doesn't work it is likely you'll be up for a new HDD and reinstall of OS and applications - hope you have your data backed up.
Sorry I can't be more positive..
You could try Lenovo support.

Purchased my HP media center PC 11/26/06 with XP installed and a free upgrade to Vista. Upgraded to Vista in April with no problems. I purchased an Ipod in July and while installing Itunes, the system crashed with a blue screen that ended up with something like "memory dump." Had to physically turn off computer and when turned back on had a message "missing operating system." Called HP and Itunes and ended up having to restore computer. Have had this happen on two more occasions. This blue screen comes on frequently while working in Adobe Photoshop Elements 4.0. Recently upgraded to 6.0 and have had no blue screens. Last night computer was acting fine and I turned it off. Today when I turn it on I receive the "missing operating system" messsage on a black screen. I am tired of restoring this computer and reinstalling all my software and backups. Any ideas on solutions to my problems? Is there a way to get around having to do a restore and then reload Vista, etc?

The computer has an AMD Athlon 64 X2 Dual-Core processor 5000+, NVIDIA GeForce 6150 LE graphics card; 21048 mb of memory, and a 320GB hard drive.

Hi anyone that can help me

I have had my comp for a few years now an never had this silly problem till now!
I switch on comp and I get the option of pressing f2 or f8 and when I press them I don't understand what to do next....I am not too well advanced in computers! My machine is a Packard bell with intel pent 4, on windows vista (home premium) I think.

I can't afford to buy any fancy software etc so I just need to know my best option. The only thing that I have is a recovery disc 1 that I downloaded when I bought the comp I don't recall any other discs.

Hi, i'm new to here. I just got to know that techsupportforum.com is helpful from Yahoo. So i hope someone here can solve my problem.

I just got a new computer from Dell C521 yesterday. Then, i on the computer and trying to install new applications from CD to C drive provided by Dell (eg.: Microsoft Works) and other mp3 songs from my own cd to my E Drive. C drive is for OS, and D drive is Dell recovery drive. However, everytime i tried to install new softwares or copy mp3s to my computer, after that i restart or reboot my computer, a black screen with an error message occur saying that "Missing Operating System".... So i reformat again the OS with the CD came from Dell. Then doing the same things.... and restart it. Same issue happen. What is the problem out there?

However, if i do nothing on my new computer (no install any softwares or copying files to my pc) my computer can reboot or run properly.

--------------------------------------------------------------------------
Well, i already contact local Dell supported team. They say will update me. So i hope can get their response soon. But i cant wait for them.

I have the same problem similar to the website below. In the mean time i already tried out these solution from Dell community website:
http://www.dellcommunity.com/support...d=210868#M9617

But it doesnt work for me. So can someone tell me the solution? My hard disk got no problem.

A:Missing Operating System - Windows Vista

dell stated that all computers that come with vista would come with the vista disk and instead of reformatting on the bottom left of the install screen
is the repair option
if the computer has sata h/drive after reformatting you probably need to load a driver with f6
the inicial install goes to ram and when it reboots it goes to load the h/drive
if it needs a driver loaded it will stop dead because it cannot find the h/drive

Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

Any ideas?

Thx
 

A:Missing Operating System/Error Loading Operating System

All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

Does the drive spin up when you switch on (feel it)?
Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD http://www.partition-tool.com/personal.htm and boot from it. What does the HDD look like with Easueus?

For the 2nd time in three days, when I attempt to boot, I got the error message "Missing Operating System". When I first contacted Hewlett Packard, they told me that the MBR was missing or corrupted and that I would have to reinstall everything.

I did!

Now, two days latter, I get the same message ... from the computer and from Hewlett Packard.

I'm not sure what happened the first time, but the most recent occurance happened when I attempted to reboot to Vista after running a Linux Live CD (SimplyMepis). I did not install Linux, just ran it off the CD. I closed down Linux, took the CD out of the drive, and attempted to boot to Vista. Result "Missing Operating System".

I've checked the boot order in the BIOS and even changed it so that the hard drive booted first. This didn't work.

Does anyone have any idea how to fix this without a reinstall?

Does anyone have any idea as to the cause of the problem?

Does anyone have any idea how to avoid this in the future?

I apologise if this is the incorrect place to post my question (first time using the forums)
I have a Dell Inspiron 3646, Intel(R) Celeron(R) CPU J1800 2.41 GHz 500GB SATA Hard Disk Drive
I was attempting to boot Linux from a live USB.
The previous OS was Windows 8, no recovery disk was supplied with the computer.
I entered the BIOS menu to change the boot order from the HDD to the USB.
Before I changed the boot order, I changed the Boot Mode from UEFI to Legacy.
(I was following instructions on the internet and mistook this as the boot order.)
I didn't change this back before I continued and can't remember if the default setting was Legacy or UEFI.
I booted from the live USB and continued to try and install the ISO of Linux onto my HDD.
The install encountered an error and took me to a shell.
I exited the shell and rebooted without the USB.
I now receive the following error message
"No boot device available
SATA 0: Installed
SATA 1: Installed
Strike the F1 key to retry boot, F2 to run the setup utility"
The above error message is repeated on reboot.
F2 takes me back to the BIOS menu.
I have run the Dell pre-boot diagnostics and all tests were passed.
From my internet searches I understand that I may have corrupted the boot loader that was on the HDD.

IS THERE A WAY FOR ME TO REPAIR THE HARD DRIVE?

I would greatly appreciate any help, guidance or advice on the above issue.

Please let me know if you require any further information in order to be able to ... Read more

A:Missing operating System

1. welcome to Tech Support Guy
2. Sorry you have waited a few days for a reply
3. If the computer came with Windows 8 pre-installed then it is most certainly a UEFI boot mode and windows 8 or now 8.1, I presume would be installed on the hard drive in GPT format
4. The boot configuration data for windows would actually involve the booting from a partition titled windows boot manager, this would then hand control to to Windows to complete the of windows
5. It is more or less impossible to decide what you have done, as there is no way of knowing where you installed or attempted to install the Linux based system
6. Your first approach if you have not already done so is to return the boot mode to UEFI in the firmware. Save changes and exit
Shut down
Now when you power on select the boot menu and ascertain if you have an option of windows boot manager
7. The no boot device available is because either - you have attempted to install Linux by selecting the wrong partition or space in which to install it
OR due to the legacy mode when the firmware is looking for the wrong boot loader
OR indeed you have formatted the partition from which windows 8.1 would boot.
8. If the resetting of the firmware to UEFI mode does not achieve anything then you are going no further until you have either the Windows 8.1 installation media for your version - eg 8.1 Professional or Home, the bit version 32 or 64 and the language
You make that from here

A:Missing Operating System

Welcome to TSG....

Contact the manufacturer of the computer and order a complete set of recovery disks for thsi computer, they will arrive via snail mail with in two weeks after paying for them.

Also while you are waiting you can remove the hard drive from this computer and install it as a slave drive on the second IDE cable and when it is seen by windows then manually backup all of the important data from this drive to the computer it is installed in and burn to another media like CD-R's, DVD or other media that you prefer.

After this is done if you are impatient you can press F10 and try to restore the computer back to when the computer was brand new but this looses all of the data.

A week ago I turned on my computer, it started booting up and I got the message "Missing operating system." I used level 2 of Spinrite 6, which seemed to work fine but did not solve the problem. Using my Windows 7 installation disk, I got to the command prompt X:\sources and then did the following:
c:
The volume does not contain a recognized file system.
d:
The volume does not contain a recognized file system.
diskpart
select disk 0
list part
Partition ### Type Size Offset
Partion 1 Primary 100mb 1024kb
Partion 2 Primary 223mb 101mb
select vol c
Volume 1 is selected volume
Detail part
Volume ### Ltr Label Fs Type Size Status Info
Volume 1 C Raw Partition 100mb Healthy
ditto for selecting volume d to get the following:

Volume 2 D Raw Partition 223gb Healthy



Suggestions would be appreciated. I do not have a backup of the SSD drive. While it would not be a major disaster if I had to reformat the drive and do a clean install, I'd prefer making a good effort to recover the data. I have limited computer knowledge. Thanks.

Your partitions are showing up as Raw, it may be too late, but you could try a Live version of Linux.

My personal favorie Zorin OS - Home

Or try this

TestDisk Step By Step - CGSecurity

i tried to put the recover stuff onto the discs and i was on the first one when my computer crashed so i had to turn it off wilst it was in the middle of it and when i try to turn i on i just get issing operating system on the screen

Hi. . .

The recovery DVDs must be burned per the manufacturer's instructions so they are bootable discs.

Also, make sure that your BIOS settings place the DVD drive 1st in boot-up order.

You should have a manufacturer recovery partition on your system - the majority of Vista Systems do.

Hi,
 
I have a Dell Inspirion desktop. About 10 days ago I installed Windows 7 on this computer. Everything has been working fine, did all the Windows updates. Today I turned the computer on an it says "Missing Operating System".
 
Before I installed Windows 7, I ran the Windows 7 Upgrade Advisor. I met all requirements. Also ran the compatibility wizard.
 
After installing Windows 7, I have rebooted the computer dozens of times after updating.
 
I'm hoping someone could help me this problem. I'm trying to avoid reinstalling Windows 7 again. But if I need to reinstall Windows 7 again that's not a problem.
 
Thanks,
Mike

You can boot up from your Windows media (dvd?) and go to the repair options on the 2nd page.
From there, you can do an automatic startup repair which will hopefully repair your machine.

Hello, i have turned my pc on and it says 'missing operating system'

is there anyway that it can be fixed without the operating system disk. I would be gratefull of any help.. thanks.. :D

A:''missing operating system'' ???

Sadly, the only way to fix this is though a installation disk or a recovery disk. Also, some manufactures sell a recovery disk for ~25 USD. this does depend on the manufacturer of your PC (dell, HP, and the like)

Also, is this a duel-boot, or just two PCs (under your name it lists XP and Vista)

Hey there,
i've a feeling i'm in a fair bit o' trouble here so any help or ideas are welcome....

I left my pc defragging last night only to come back to it later and found it had restarted with the words "Mising Operating System". It scans for boot record from the floppy then IDE 0 and says "OK", then it comes up with the "Missing Operating System" line.

My Drive is all 1 partition by the way, laziness stopped me from getting around to changing that.

Has anyone else been in this situaion and got it sorted out???

Please help me!!!!

By the way i'm using Win 2000 Pro and don't have an emergency repair disk....

A:Missing Operating System

If your luky...putting restore disk in....close it and starting comp will get that to boot to re-install. open your case and see if anything is still melting. Wait for someone who knows more than me to really do anything though. sounds like your comp is really jacked up -joe

swabbye7 Hello;Allow me to welcome you to the HP forums!I read your post about missing operating system and wanted to help -- but need more information.If you can, please follow the directions in this link to find the detailed product number of your PC: http://support.hp.com/us-en/document/c03754824?jumpid=reg_r1002_usen_c-001_title_r0001If that is not possible, then look for a sticker on the PC that includes the product number and post that here.  If the battery is removable, the sticker is likely to be in the battery compartment. Also, need to know what Windows version your PC is running. We need that information because troubleshooting steps are different for the various Windows OSs.IF it's running Win10, did it come with that preinstalled?  If not, what was the prior OS of the machine and how long ago did you do the Win10 Upgrade?  And, was your machine OK after the Upgrade or were you having problems, and if so, what were those problems? We can proceed once you provide the information.Thanks

upon starting my computer it informs me of a missing operating system, my system is a dell xps, I have no system image disks. I have purchased a recovery usb from dell, now that does not work. I have also tried a system repair disk and that lists no operating system. I have no idea of what drivers to load and from where.

Not sure if secure boot would be affecting your machine or not but you might review your Bios and advanced boot options for secure boot.
Post some images if you want for the options you show.
