What do you do if your computer doesn't have an operating system?

I recommend Debian Linux:\n\nhttp://cdimage.debian.org/debian-cd/3.1_r1/i386/iso-cd/debian-31r1a-i386-netinst.iso\n\ndownload this ISO on a machine (that has an OS) and burn the image (make sure you don't burn the FILE, if you burn it and navigate to the CD and find a .ISO file, you did it wrong).\n\nStick this CD into your machine, and answer the questions as they come up.  \n\nLinux isn't as friendly as Windows, but it's free, and you can do some cool things with it.

I would reformat and reload the operating system.\n\nCoach

Copy this file onto a CDROM or floppy. (Should be in the windows&#92;system32 folder.  Boot the "broken" computer into the command prompt.  Press F8 during the bios boot, before the Microsoft Windows screen appears.  Change directory (cd&#92;windows&#92;system32).  Copy this file from the floppy / cd to this folder.  copy a: or d:*.* c: (replace).  Reboot the computer. Back to a happy computer again!  If this does not work, you will need to boot from a Windows XP install cd and select the command prompt option.  Repeat the copy steps again.  \n\nEnjoy\n-Koz\ncomputer service phoenix\nhttp://www.affirmtech.net\nAffirmative Computer Services\nComputer Service with a SMILE!

What's the operating system you are using ?

Reload the OS or try buying a new comp

Assuming (isn't stated, so I'll go for most popular) you are using win XP, insert the installation disk and then boot. Then access the recovery console (see sources for a how-to). Then run fixmbr (command line interface, so type and hit enter). This repairs the part of the disk that contains the information on where Operating systems can be found on the disk, this may help!\n\nAdditional note: maybe read the warnings first - if you have a dual or multiple boot systems (more than one OS) or a non default bootloader, this may cause problems. If you have no clue what I'm on about, then you probably don't have either.

hit your Start button, pull up programs, go to accessories, then go to system tools. Finally go to system information and pull that up. explore in there. if that dont work, hit the start button and pull up Help and Support.While in Help and Support, pull up the Find button and type in model no. that may help. Good Luck

What Operating System?!?!?!?

Your best option when parting with a computer would be to do a complete system re-format. Did you get a system restore cd with the machine? Or do you have a Windows operating system cd you could use to re-install from scratch? If not....find a friend who can do it for you!

Restart the system, keep hitting the F8 key until you get into the menu, at the menu select "Use last known good configuration"\n\nIf that works then bingo, if not then if you can get into windows at all then go to start--> run and type ( or if you are lazy copy and paste this command )\n\nsfc /scannow\n\nMake sure to have the xp disc or the recovery disc handy.\n\nIf that does not work then back up all of your data and do a clean install.\n\nHow to do a repair install :\n\nhttp://www.michaelstevenstech.com/XPrepairinstall.htm\n\nHow to do a clean install :\n\nhttp://www.michaelstevenstech.com/cleanxpinstall.html\n\nHope this helps.

u can use Knoppix LiveCD (if u can use Linux based OS) or u can use Emergency Boot Disk like Hiren's Boot CD, Windows XP Live CD, etc

without knowing the os i cant give suggestion

One last try, start the system and keep pressing the key "F8" you will come to a screen where it will ask you how you want the system to start........choose the number which corresponds to "last known good configuration"....... if everything is good then you can have your system working....\n\nElse if you can get a help from your firend take his OS CD and reload your system, but you got to remember your systems original OS Key number.........

if the " operating system not found" comes up it means that your system isnt reading the boot files on your hard disk right or some of the files maybe corrupt, try restoring your computer to a point before it did this, and if it still does it then you have a problem in the boot files or hard drive connection. try using pc doctor to fix the anomalies

Install the OS again unless you know how to restore all the system files I would just stick to doing an install.

If you have the CDs/floppies for your computer's drivers, try those.\n\nIf you don't, download off of the internet from another computer, then put it on a CD or a flash drive, then put it into the original computer that doesn't have internet.
