Get a copy of windows 7. Put it in your DVD drive. Reboot the PC and follow the instructions. It should boot to the disc drive, if not, you will need to go into setup and change the pimary boot device to DVD drive.

Installing windows 7 isn't difficult. First, you need the disk to install it from. If you don't have that, Microsoft no longer sells this version, so it will be harder.
If you want to keep your programs and data, there is a package, "PC Mover" that you can buy that will help you preserve all your data and programs. I've used this many times to help upgrade systems like yours.

SOURCE: Missing Drives for Dell Optiplex GX260 PC Desktop Problem

if you don't have the cd with the drivers and utilities, then you can download the drivers online with another computer. (you will need a thumb drive or cd to save it on) you will also need to make sure you know what brand of ethernet card your computer came with. once you get that ethernet card working, you can get online and download the remaining drivers, possibly through windows update. be sure to select custom update, not express, so it will search for the hardware drivers for you.

SOURCE: XP won't recognize 2nd SATA drive and shows 1st SATA drive as drive F:

To get Windows to recognize the 2nd HDD, you have to initialize it in disk management.

http://www.simplyguides.net/guides/prepare_second_hdd/prepare_second_hdd1.shtml

As far as the drive letter for the OS install, that was caused by the HDD not having an existing partition and other drives in the system having one (Either USB Drive, Printer with a card reader, 2nd Internal HDD)

Here is a Microsoft article on how to change it, but you'll notice MS doesn't recommend you try it. (Personally, I can live with ah HDD with a drive letter other then C:, so can Windows.)

http://support.microsoft.com/kb/223188/en-us

In the future, when installing XP, boot to the CD, run the install to the point of formatting the hard drive. Once formatted, turn off the computer, reboot to the XP install again, the HDD will be assigned C:

As far as the drivers go, they needed to be installed in this order:
Desktop System Software
Chipset
Video
Audio
Network
Modem

SOURCE: My Dell Optiplex 745 "No Boot Device Available"

No boot device means that the computer cannot find a drive that has a operating system files and therefore cannot boot up.
This usually means that the hard drive in the computer is faulty.
You need to get a new hard drive and install Windows on the hard drive, together with the drivers for the computer's installed devices and programs to get a working computer.

Hello i have a Dell Optiplex 745 it boots up and starts windows 7 normally then the the screen goes black does anyone know how to fix it?


Can you boot into Safe mode. It is usually done by pressing a specific key during the POST session. If you can, then boot into safe mode and delete the Video Driver. Reboot. TYou should have a VGA display, download and install the video driver again.

With sata there are two cables, just like ide. One is the power and the other is for data. The data cable goes from the device to the motherboard. The power comes from the power supply. If your power supply does not have a sata connection you can purchase an adapter that will turn an available 4pin Molex into a sata connection.

Problem with sata HDD probably?


check the bios settings first. if you can see your sata hdd and dvd rom drive then you can install it with no problem. or else try to replace the cables of the hdd if the hdd is not showing up in the bios.
also check that the hdd is set to master drive and dvd also set to master as they are on different connections.

My dvd rw is not detected


Sounds like you need your manufacturer's SATA drivers.

This problem exists a lot when installing Windows from scratch on SATA hard disks. When you start the installation, Windows prompts you to "load additional drivers". It's at this point you put a floppy disk with the SATA drivers in.

If your install is already working, but just stopped as you say... then you could hunt around the BIOS for a SATA "compatibility" mode, which will get you booting straight away. Install the SATA drivers and you can then put the drive back into normal operation instead of compatibility mode.

This is also the reason why your other hard disk with Windows can see the SATA disk and optical drive... it probably has the SATA drivers installed.
