I can't install OS on my msi ms-7104 desk top pc with my new sata dvd R/W optical drive.Earlier i have used ide optical drive from which os can be installed sucessfully .Even with default bios setting my sata dvd drive is not detected.I had changed raid to ide in bios,then my dvd drive is detected,with my previously installed xp, dvd drive is working fine but can't install new OS with same setting,that is format hard disk and install new OS,i had tried to install xp that is boot from dvd drive ,it get hang.

i dont think it matter if your system detects it as sata or ide, both interface will work in installing OS, the important thing is you changed your boot order. originally it was supposed to boot in 1st drive whichever it is hard drive or dvd drive. go to bios then follow the instruction in how to move the order of boot sequence, mine is SHIFT key then PLUS.

What is the specific problem you have connecting this internal drive? This is an internal SATA optical drive for a desktop with a standard 5 1/4" drive opening. Many optical drives ship as OEM devices; you will need to reuse the data and power cable from a previous drive or purchase a SATA data cable (7 pin). A locking cable can help keep the cable connected to the drive. If your power supply (PSU) doesn't have SATA power connectors (15 pin), you will need an IDE to SATA adapter. Most online cable shops have the best prices for these.

If your computer doesn't have a SATA port available, you need to add a controller card or use a SATA to IDE converter.

If your case is a ultra-small form factor, you may have a modified optical drive opening. These cases use a slim optical drive (mostly sold as laptop drives). In that case, get an external 5 1/4" enclosure or a USB to SATA adapter.

If you have the drive in the computer, press the Eject button. If that works, then the power cable to the drive is fine. Check the data cable to both the drive and the motherboard. My old computer had SATA connections on the motherboard that would not allow the cable to lock. When I bumped anything in the case, I had to check that the cable was re-secured.

What OS are you using? For most versions of Windows, your OS should have the correct driver or find it with Windows Update (if the computer is on the network). Try launching Windows Update and checking if an optional driver is waiting to be installed. I don't know if Unix or Mac OSX drivers exist for this drive. You may need a different optical drive.

The drive should now be listed in the storage devices (Computer/My Computer). If you can't read files, try another disk. If it still doesn't work, try cleaning the lens or a different drive. Some drives are sensitive to the power supply for burning optical discs.

I hope these suggestions help. Please add a comment with the specific problem and case/OS that you are using for additional solutions.

Schematic

The eMachines T6532 uses an MSI MS-7207 motherboard.
Also known as the KN8GM2-L,

http://www.msi.com/product/mb/K8NGM2-FID--IL--L.html

[ http://www.newegg.com/product/product.aspx?Item=N82E16813130041 ]

The MSI motherboard has provisions for using, EITHER an
IDE (PATA) harddrive, or a SATA harddrive. (Or more than one)

Two different technologies.
I will explain both, using an IDE (PATA) harddrive,
OR;
Using a SATA harddrive;

On the MSI Support page above, click on the Download tab.

(7207v2.0(G52-M7207X5) next to the red Adobe PDF icon)

There is the Motherboard Manual

The MS-7207 has two IDE slots;

IDE 1, which is Yellow in color, and close to the outside edge of the motherboard.
Should have IDE 1 silkscreened on the motherboard, below it.

IDE 2 is Yellow in color also, and right next to IDE 1.

(IDE 2 is in-between IDE 1 and the Ram Memory slots.
The Purple, Slot 4, ram memory slot to be specific. {DIMM 4 )

IDE 1 is used for an IDE harddrive.
IDE 2 is used for an IDE optical drive.

TWO IDE harddrives can be put on a single flat ribbon IDE cable,

http://en.wikipedia.org/wiki/File:ATA_cables.jpg

NOTE that there are two styles of IDE flat ribbon cables;
40-wire cable,
OR;
80-wire cable.

BOTH have 40 socket holes in their connectors.
(ONLY 39 are used, so one hole May, or May Not be blocked off)

How to connect to a 40-wire IDE cable, or an 80-wire IDE cable,

http://www.mikeshardware.com/howtos/howto_connect_ide_hd.html

An IDE cable usually has a Locating Lug on it's connectors, in the middle of the connector; and on one side,

http://en.wikipedia.org/wiki/File:PATA-cable.jpg

Here you see the Locating Lug as being two separate 'ridges'.
Some styles the Locating Lug is single block.

The motherboard connector has a matching Cutout on one side.
The Locating Lug lines up with the cutout when installing the cable.

The Harddrive, and optical drive (CD/DVD drive), will have a cutout on their circuit boards.

There are 40-pins. (Only 39 are used if so)
One of them is the number 1 pin.
The IDE cables are plugged into the motherboard, with number 1 pin lining up with number 1 wire, in the IDE cable.

Same when the IDE cable is plugged into a Harddrive, or optical drive.

IF, there is no Locating Lug on the IDE cable;
Look for the faint RED stripe, on the side of the IDE cable.
Number 1 wire is on the same side, as the faint Red stripe.

When plugging into a motherboard, Number 1 pin is on the Bottom.
The faint red stripe on the cable, goes towards the BOTTOM of the motherboard.
(Motherboard installed in computer case)

When plugging into a Harddrive, or optical drive; the faint red stripe ALWAYS goes toward the power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

This shows you the Back of an IDE (PATA) harddrive, and the power cable used for it.
If -> No Locating Lug on IDE cable, the faint Red stripe goes towards the power cable.

This is a 4-pin standard Peripheral power cable.
Note when installing the rounded corners ALWAYS goes UP.

[This power cable is frequently, and erroneously; referred to as a 'Molex' power cable.
Molex was just the first manufacturer of the power cable CONNECTOR. Name STUCK.

Kind of like calling an adjustable open-end wrench, a 'Crescent wrench ]

A SATA power cable is used for a SATA harddrive, or SATA optical drive,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

There is an L-shape in the SATA power cable's connector.
It matches an L-shape on the Harddrive, or optical drive.

Between a SATA power cable's connector, and a SATA data cable's connector; a SATA power cable connector is the LARGER of the two.
A SATA power cable has 15-contact pins.
A SATA data cable has 7-contact pins.

A SATA power cable's connector may have a LOCK on it.
Usually a Tab, or 'bulb' type affair.
It is pressed down with the thumb when installing, or removing the SATA power cable.

This is a general example of a SATA data cable,

http://en.wikipedia.org/wiki/File:SATA_Data_Cable.jpg

Now you can see the L-shaped opening a little better, that both the SATA data cable have, and the SATA power cable, has.

In the photo the SATA data cable's connector, is a 90 degree bent Elbow.
This style of connector is usually used on the Harddrive, or on the optical drive.

A Straight connector style is usually used for the Motherboard.
However, you can use a SATA data cable, that has a Straight connector on both ends.

Looking at your motherboard, installed in a computer case; there are 2 SATA connectors on the motherboard.

(CAN, be up to FOUR)

I see one motherboard reference where they (2) are Orange in color, (Newegg), and the motherboard manual shows them (2) to be Purple in color.

They are located towards the Bottom/Right corner of the motherboard.
Above the CMOS battery.

The SATA connector that is closest to the Outside edge of the motherboard, is SATA1 (SATA 1)

The Harddrive plugs into SATA 1.

An optical drive that is SATA, will plug into the SATA2 connector.
To the Left of the SATA1 connector.

KNOW THIS;

DOES NOT MATTER, which SATA connector you plug the Harddrive, or optical drive; into.

The beauty of SATA, is that you can plug the Harddrive or optical drive into ANY SATA connector, (On ANY motherboard), and BIOS will find those devices.

BIOS looks FIRST, to see which drive has the Operating System on it. (Windows)
THAT, is the Harddrive.

After finding the drive with the O/S on it, then BIOS will find all the other drives. Removable, or not.

So there you have it. A lot of reading.
You need a power cable, and a data cable to the Harddrive.
Same thing for the optical drive/s.

To have me clarify anything I have stated above, please post in a Comment.

For additional questions please post in a Comment.

Perhaps your bios is set to boot from the 1st device it 'sees'.
When you add the dvd drive, maybe the device order gets shuffled up, making the dvd drive 1st. So, you need to check this by looking at the boot settings on the bios screen and change the boot order if necessary.

Did you install a SATA or an PATA (IDE) drive?

First check that the data cables are connected to both the hard drive and the motherboard. (I know that I've frequently had the cables come loose from the motherboard on my ThinkCentre 8433 when I work in the case.) Also check that the power cables are firmly connected.

Next make sure that you have no disc in the DVD writer. (Or enter the BIOS by pressing F1 (IIRC) repeatedly on start up. Make sure that the hard drive is the boot disc.) While in the BIOS, you can check if the hard drive is recognized by the motherboard. If you don't see the disc listed, recheck the data and power cables.

If the hard drive was working before you replaced the dvd drive, you may have changed the master/slave assignment on the drives (if they are both IDE). Remove the drives from the computer and check the jumpers. (These will depend on the manufacturer. Use either cable select or master/slave as needed) The boot drive should have the jumper set to master or cable select. In the case of cable select, the boot hard drive should be connected to the black connector. The slave drive goes to the grey connector.

If you connected a SATA drive, try swapping the SATA ports (SATA 0 or SATA1) that has the optical drive connected to it.

The next thing to try requires either the Windows install or upgrade disc for your version of the OS (including the Service Pack) or a third party partition manager/repair utility disc. You'll need to reset the boot order to boot from the optical drive (or press F12 on starting the computer). Use the Recovery Console (for the Windows disc) to find any existing OS installs on your hard drive and attempt to repair the master boot record or boot sector if it still exists on the drive. Please add a comment with your OS for specifics on using the Recovery Console. (I replaced my WinXP with Win7 and the methods are different.)

You may have been unlucky and had the hard drive fail while you were working in the computer. See if the recovery partition (F10 on boot) still works or use your system image (Rescue and Recovery DVDs) will restore your computer to the last backup. Try doing the restore to a new hard drive if the recovery discs don't work.

I hope this helps. Please add a comment with any comments that will help me give more specific assistance for your missing OS.

SHUT DOWN COMPUTER AND CLEAR CMOS BY RESETTING JUMPER ON MOTHERBOARD AND THEN RETURN JUMPER TO NORMAL POSITION OR USE RESET BUTTON. UNPLUG ALL HDD SATA CONNECTORS FROM HDD. BOOT COMPUTER TO BIOS. MAKE SURE ENABLE ALL SATA IS ENABLED, PRESS F10 AND EXIT.YOU WANT TO SHUT DOWN AGAIN. NOW REATTACH SATA HDD AND CONNECTORS AND BOOT TO BIOS AGAIN. NOW HIT F10 AND LET COMPUTER RESTART AND LOAD INTO THE OS. LOGON AND CHECK DEVICE MANAGER..SHOULD BE THERE. IF NOT CHECK MOTHER BOARD WEB SITE FOR BIOS UPDATE. IF BIOS UPDATE DOESN'T DO THE TRICK, SHUT DOWN AND DISCONNECT THE IDE DRIVE, UNLESS IT CONTAINS YOUR OS. TRY BOOTING TO BIOS AND CHANGE ORDER OF 1ST BOOT OPTIONS, HIT F10 AND EXIT AND ALLOW COMPUTER TO BOOT TO OS, THEN LOGON, GO TO DEVICE MANAGER AND REMOVE IDE AND RESTART, ONLY IF THIS HDD DOES NOT CONTAIN OS. YOU SHOULD BE FINE AFTER THIS, OR INSTALL YOUR OS ON THE SATA HDD.

You must have added the SATA drive after setting up the IDE. If both drives are using the same os this will not function. Ony one drive can have the os on it. All SATA's are seen as a master.
To correct this problem, disconnect the IDE drive. Hook up the SATA drive. Again if the SATA has the os on it everything will run. Change the jumper on the IDE and set it as a slave. Hook the IDE up. Enter the bios & do not list the IDE in the boot to section. Problem solved. While in windows, format the IDE drive.
You do not want windows thinking you want a dual boot system.
So you understand, in the bios -boot settings this is how things should be listed.
Boot device 1 Sony Optiarc DVD drive
Boot device 2 WD raptor SATA, In-stall your os to this drive
