Re: missing operating system
You may need to access your system's setup. Usually by pressing a certain key during power up. Sometimes it's the DEL key, sometimes it's an "F" key. In the setup you need to tell the PC to boot up on that drive first, then save the setup. You neglected to say if your boot disc is floppy ot CD, but that drive must be bootable in the setup.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Sounds like your system is booting from somewhere other than the hard
drive or you have a music cd or movie dvd in the DvD/CD drive when you
booted the laptop. If so, remove the music cd or movie dvd and reboot.
You want it to boot from the hard drive.
Turn the computer off and press the power button to reboot it. Notice
the screen and watch for which key it says to hit to change the Boot
Order or Boot Sequence. You have to hit that key when you see the
message otherwise it will be to late and you will need to start over.
Select the Hard Drive and let it boot up. This is a temporary change and
only good for this boot cycle. You'll have to do it each time you boot
or you can make it permanent.
To set your boot order or boot sequence permanently reboot the computer
and look at the screen to hit the key it says to get into the Bios or
System Setup. Hit that key when you see the message or it will be too
late and you will have to restart it. When you get into the Bios or
System Setup tab over to the Boot Order or Boot Sequence. The normal
boot order should be the DvD/CD drive 1st, the Hard Drive 2nd. With
this setting you have to make sure nothing is in the DvD/CD drive when
you boot the system or it will try to read it as a system disk and give
you an error if it can't boot from it. If there is nothing in the
DvD/CD drive it moves to the next boot device which is the Hard Drive.
This setting is the best because it will allow you to use a Repair Disk
or Operating System Disk to fix your computer when the hard drive has
What are you trying to boot from? It sounds like you selected something other than your hard drive.
When you power on the computer take note of which key it says to hit to Change the Boot Order or Boot Sequence and hit that key. This is a one time change that will get you booted up. You should select your Hard Drive to boot from.
To make the change permanent you will have to get into you Bios or System Setup. Reboot the computer and notice what key it says to hit to get into the Bios or System Setup then hit that key. When it opens up, hit the tab that lets you change the boot sequence or boot order then save it and exit out. Normally you want the DvD/CD drive 1st and the Hard Drive 2nd. This way if your system has problems you can insert a repair disk or operating system disk to fix it in the drive. The only drawback is that you need to make sure nothing is in the CD/DvD drive when you boot up (such as a music cd or movie dvd) or you will get a message telling you that it can't boot from the device.
If you like, you could just make the Hard Drive as your first boot device.
Your computer is trying to boot from a Network or Lan. You need to go
into the Bios or System Setup and change the boot order or boot
Reboot the computer and notice what key the screen says to hit to get
into the Bios or System Setup and hit that key. Change your boot order
or boot sequence. The best sequence is to have the CD Drive 1st and the
Hard Drive 2nd. Changing this in the bios or system setup will make
the change permanent. Just make sure when you boot the computer that
nothing is in the CD drive unless you have a repair disc or operating
system disc in it.
You could make a temporary change but then you
will have to change it every time you boot. If you notice the screen
when you boot it also gives you the key to hit to change the boot order
or boot sequence. This will allow you to change it just for this time
that you are booting.
Sounds like you may have to change the boot up drive in your bios.
To enter you bios, you have hit Del or an F key as your computer begins to boot up (watch the screen, it should tell you).
Once you've entered your bios, you have to find where in the bios it allows you to set the order of boot devices. This is commonly under "Power Up" options or on the more recent BIOSes, it'll be under "Boot Devices." Once you're there, refer to the on screen instructions on how to change the order. The most common ways are using the page up/down keys, the +/- keys or the left and right arrows. Set your Seagate Barracuda to be the first place it boots from and you should be able to boot from it.
Computers indicating missing operating systems have means to resolvement. First, ascertain that the hardware components are in place prior to restoring the missing programs. For example, ascertain that the computer has disk storage components. In situation that hardware devices are within device only has encountered an impact causing crashes or volatile data media would require replacement. For example, ascertain the brand of the computer from where hard disk storages are purchased from retail. Once acquiring new hardest also requires acquiring new operating system complementing the component reviving computers. Prior to visiting computer component retail facilities requires ascertaining that brand of computers also ascertaining the prior operating system from which determines reviving the remaining devices. For example, computers that once performed on windows XP requires acquiring similar versions from retail to recapture the remaining components at installations. Significant importance with replacing computer operating systems is reacquiring the entire users programs that become volatile as a result of reinstallations. For example, computers require antivirus programs as an alternate program least made available with new operating systems. Also computers require new programs that were within prior device that would have become compromised with the crash or replacement. While at the computer retail market, ascertain from computer experts about resource programs that makes an improvement also complementary with new installations.
You are missing the operating system time to re-install the operating system. It is corrupt and will not start windows without the system files. So simply re-install the original software that came with your computer.
chech to see that no disk is inserted into the cd drice and the floppy drive.
there must be a system file missing
might have to reboot the system
if nothing comes up them there is a problem with the hard disk or the operating system is not fully installed
You hit the problem right on the head, NO BOOT. All computers have to have a system disk to read whether it is on a floppy or hard drive. your computer is not reading your hard drive. It either is really screwed up from the boot, or it has been formated and has nothing to read. Try installing a new copy of windows or inserting some type of bootable disk. if that works, Install your windows operating system. Insert a disk in your D drive or your CD drive letter and turn the computer off, restart the computer and the disk should boot your computer. Good Luck.
You will have to remove the hard drive and back up all the files you wish to save. You can do this with a 7 dollar USB hard drive adapter cable from E-Bay. Save your files on another computer. You then have to be able to boot the computer from the optical drive. Before going through all the following steps just try to boot from the optical drive with the operating system install disk. If it boots from the disk you can skip all the other instructions here and reload your operating system and drivers and restore the backed up files and you are done. If you can't boot from the optical disk then read on.
Make sure the optical drive is the first device listed in the boot order in the system bios setup screen. You can get into the system bios setup screen on most computers by hitting the F2 key or DEL key as soon as you hit the power button. Which key depends on the bios used in the system, Award, AMI, Intel, ect... Try F2 key first as this is the most common. If the bios setup screen is password protected also, remove the bios back up battery on the mother board to erase the password stored in the bios and replace the battery. If the password is still there You will have to locate the EEPROM that contains the password and short pin 3 to pin 6 and power up the pc. This will erase the electrically erasable programmable read only memory chip. You can find the location of this chip by googleing for it. search for the string" bios password chip location (make/model of pc)" use variations of this format until you find a link to a site or forum with the location of the bios pass word chip. Once you are in the bios setup set the boot order to reflect the optical drive as first in the boot order. Hit F10 to save and exit. Now you have to reload the operating system and all the device drivers for your hardware(video,sound,LAN,ect..). Now that you have a fresh operating system installed restore all the files you backed up earlier and you have done it !!!
In some very rare cases in very high end computers you may have to actually replace this bios password EEPROM. In this case you simply buy a new one and swap it out.
This is every step needed to reactivate a computer with a locked password(Bios and Operating system). I spent an hour typing this out carefully making sure it was written so that anyone that reads it will be able to understand it and carry out the full procedure no matter what obstacles may arise and the solutions to work around these obstacles. If for some unforeseen reason you can not perform this procedure you can contact me directly email@example.com with your phone number, country, and a time when you will be available and I will call you for free world wide and walk you through the process step by step until you have restored the computer. I will even send you any software you might need, all for nothing more than the fixya rating. I hope you find this information useful. If this keeps just 1 perfectly good otherwise computer out of the landfill My mission will be accomplished. This information is not intended to be used on stolen laptops or computers. I only want to save as many of the 1000's of good computers that get discarded every year because of this easily remedied problem. Now go rescue that PC ! George
