Did you add this as a second hard drive? Or did you replace the original one with this one? If you installed this as a second hard drive, what has probably happened is that the BIOS is now looking at the new drive, thinking it is the boot drive. If you go into the bios, you will see two items under "bootup". One is boot device priority. This is where you select whether you want the CD, or the HDD, or the USB to be the first priority boot device. Then there is another for HDD boot priority. Look under that one and ensure that your original HDD is selected as the primary boot disk.

    The original hard drive was removed. I got the computer from a side job the owner pulled the drive before giving me the computer.

    Ok, You need to have a bootable Operating System disk taht you can use to install the OS. What the computer is telling you right now is that there is no device that is configured as a boot device. Go into you BIOS and make sure that the boot order is set to use the CD/DVD drive first. WHen you start the PC, insert the OS boot disk. It should start setup automatically. Follow the prompts and install the OS. You will need to partittion and format the Hard Drive first, but setup will guide you through this. Warning! The Windows setup disk will provide a generic video driver, but you will probably not have any audio ot network capability until you install the DELL drivers for your model and for the OS you are installing. You can get them fro the DELL website, under support.

    Also, during the Windows setup, the computer may need to restart once or twice. This is normal. During the reboot, you may see a message to press any key to boot from CD/DVD. Do not press a key during the reboots! The setup program will resume where it left off. Pressing a key wll cause setup tp rewstart from the beginning..

SOURCE: installed new hard drive now will not boot

1. First of all, you must open the computer case (with power off), and werify the power cable and data cable of hdd. please detach and put them right back.
2. then power on your pc
3. you MUST press F2 for setup utility in order for correct setings of your bios. the message "strike F1 to retry boot, F2 for setup utility" came from the computer bios, not from Windows XP CD.
4. verify if you followed the correct procedure of installing an new hdd as is described on page 66 of owner's manual from dell.


"Installing a Hard Drive
1 Unpack the replacement hard drive, and prepare it for installation.
2 Check the documentation for the drive to verify that it is configured for your computer.
3 Remove the hard drive bracket (see page 64).
4 Attach the hard drive to the hard drive bracket:
a Place the small bracket tabs into the drive-securing screw holes on one side of the drive.
b Gently swing the drive toward the bracket and align the three screw holes on the other side of the
drive with the screen holes on the bracket.
c Attach the hard drive bracket to the hard drive.
d Insert and tighten all three drive-securing screws.
5 Install the hard drive:
a Place the two bracket tabs into the drive slots inside the bracket for the additional hard drive.
b Swing the bracket forward so that it is flush with the bracket for the additional hard drive.
c Replace the bracket-securing screws.
6 Connect a power cable to the drive.
7 Connect the data cable to the drive and to the system board (see page 53).
8 Close the computer cover (see page 75).
NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into the
computer.
9 Connect your computer and devices to electrical outlets, and turn them on.
See the documentation that came with the drive for instructions on installing any software required for
drive operation.
10 If the drive you just installed is the primary drive, insert a bootable floppy disk into drive A.
11 Turn on the computer.
12 Enter system setup (see "System Setup" on page 80), and update the appropriate Drive option.
13 Exit system setup, and restart the computer.
14 Partition and logically format your drive before you proceed to the next step.
See the documentation for your operating system for instructions.
15 Test the hard drive by running the Dell Diagnostics (see page 36).
16 If the drive you just installed is the primary drive, install your operating system on the hard drive."

that's all

SOURCE: Dell Optiplex GX280 boot problem

I just repaired two Gateway systems with similar behavior (turn on power, fan runs at full speed, no boot), and both needed replacement system boards. (These were a different model, but the symptoms are typical of a dead system board.) I got the boards from a company called Blue Raven Technology (www.blueraven.com).

Before deciding the main board is bad, try another power supply to make sure that's not the problem. Also you might try clearing the CMOS memory on the system board (either by moving a jumper usually found near the backup battery, or by removing the battery itself). Sometimes corrupted CMOS data will keep the system from booting.

SOURCE: dell optiplex gx280 won't boot up

you either have the boot priority in the bios off or you have improperly cabled your hard drive . perhaps you set it to boot to cd while installing the operating system and forgot to change the order back.
The floppy drive does not have to be present for the system to boot (if set to "not installed" in bios)
your boot devices are your cd/dvd rom and your harddrive.
Seeing as you've recently replaced the power supply , ime assuming you didnt dismantle the whole computer , just the power leads coming from the power supply, which means you only moved power , not data cables.
This would be the first thing to check -- power to the harddrive and cd rom, the 4 pin connector that sometimes connects to the motherboard and any data cables you might have bumped while changing the power cables. check these things and post here again.

When i am trying to instaling win xp .getting a error message like stop 0x00000007B in a blue screen


hello Shameeralipk,

The most popular Blue Screen of Death error in Windows is the STOP 0x0000007B error, sometimes called the 0x7b error or the "INACCESSIBLE BOOT DEVICE" BSOD.

This BSOD (which is actually the common name for a STOP Error) could mean that there's a serious hardware problem with a hard drive controller, a driver issue, or even a boot sector virus.

How do I disconnect (uninstall) a WD External Hard Drive from my computer? I am using a WD 3200AAK WD External Hard Drive and want to install a 1 TB WD External Hard Drive. I would like to use the old one...


External hard drives don't need any program installed on your computer to run. Your operating system Windows, Linux should handle it as soon as you plug the usb in your computer. The programs included in your WD external hard drive are tools to backup your data.

If you try to hook up your hard drive to a Windows prior to XP, maybe your computer will not handle it.

It is always safer to safely remove your drive using the green arrow icon in the lower right corner of your screen. This way, the drive is shut down properly and you minimize chances of fails when you plug it again on another computer.

Hope this helps!

When I try to turn my computer on i have a blue screen message saying "A problem has been detected and windows has been shut down to prevent damage to your computer." I can't login or anything. I have even...


From your request, the question is very general.

Code Stop 0x0000007B, it means "inaccessible boot device": Windows is not able to read from the device it's supposed to be booting from. That device would normally be your hard drive - but if you're getting this during Windows installation, it could be something wrong with your CD or DVD drive..

The Stop 0x0000007B error message will be displayed on your screen with a lot of other information in what is know as the "Blue Screen Of Death" or "BSOD".

Different PCs have different "IDE or Sata interface default settings" depending on the OEM manufacturer specifications. Check your OEM motherboard require any BIOS updating.

If your PC is a desktop, remove all the PCI devices installed on the PCI slots.

If you can access to the CMOS BIOS, reset the settings to default, save the settings and reboot your computer.

If the your PC can access to windows, do a "chkdsk /f/r" from the "Command Prompt".

If not you have to reinstall the OS.

Error while trying to install windows xp Stop: 0x0000007B on a dell Optiplex sx270


The most popular Blue Screen of Death error in Windows is the STOP 0x0000007B error, sometimes called the 0x7b error or the "INACCESSIBLE BOOT DEVICE" BSOD.
This BSOD (which is actually the common name for a STOP Error) could mean that there's a serious hardware problem with a hard drive controller, a driver issue, or even a boot sector virus.
In your case though, this is most likely one of 4 capacitors that are known to blow out on any SX270. Slide the bar at the back of your PC to the remove cover side and look inside for swollen caps. Remove the fans and cpu cover as well and check around there. Replace any bad ones you can find with old caps borrowed from an old motherboard if you have one, or new ones from any decent electronics parts warehouse. This fix has worked for me on every SX270 I have ever had.

If you can install Windows Vista and only XP not work for sure this is the solution :
SATA operation mode is AHCI
To change this :
Open BIOS
Look for SATA Operation Mode or somethin equivalent and change-it to IDE or Compatibility Mode.
