Samsung Superwritemaster dual layer dvdÂ...

Specs: Windows XP
I'm trying to install Windows 7 on my desktop,
which comes on a bootable DVD. For some
reason when I boot up through the DVD drive I
get the following error:

Boot from ATAPI CD-ROM:
No emulation

And the system hangs. This drive can boot up
with CDs, just not with DVDs. Why?

I've checked the DVD on my laptop, its
bootable. Its also readable on the desktop
when I'm in Windows.

Help please and thanks. :)

Are you sure you have a dvd drive?

How is that DVD drive identified in the POST screens at start up? Are you using an 80 wire 40 pin cable or is the drive a SATA type?

Do you have more than one optical drive on the desktop?
If so
- are you sure you have the DVD inserted in a drive that can read DVDs? CD-rom and CD burner only drives cannot. DVD rom and CD burner/DVD rom and DVD burner drives and combo CD/DVD burner drives can.

- many mboard bioses will only boot a bootable CD or DVD from one optical drive when more than one is connected.
If that's your case, if both drives can read DVDs, insert the DVD in the other drive.
OR - whether or not both drives can read DVDs, go into the bios and either
- near the boot order settings there is a list of optical drives - the one the DVD is in you want to boot from must be listed first.
- or - more than one optical drive is selectable in the boot order settings - the one the DVD is in you want to boot from must be listed first, or the only one.

Hi all, thanks for the replies.

Yes its a DVD dirve.
Yes its the only drive available.
Yes its an 80 pin cable.
Yes its a desktop.

Can you elaborate on the POST question? Do you mean is it
correctly identified? I don't recall right now, but I know that if I
try a bootable CD it'll run, just not a DVD.

When first starting the computer there are messages on the screens. Those are the POST files. All your drives should be identified by model number in those screens.

Is the computer new or old? DVD drives can wear out. There are two lasers in most combination drives. One for CD and one for DVD.

When you have a DVD "combo" burner drive - reads and burns both CDs and DVDs, or a CD burner / DVD rom drive that reads and burns CDs and only reads DVDs, it has at least two lasers and associated circuits. Sometimes after the drive has been used a lot, one of the lasers burns out or the circuits for one becomes wonky, but in that case, you would probably not be able to read DVDs in Windows.

Sometimes a bootable CD or DVD is not detected properly while booting after the drive has been used a lot. Sometimes that's because the laser lens is dirty, sometimes it's because some circuit or switch no longer works properly. You could try cleaning the laser lens on the drive, by using a laser lens cleaning CD. If you don't have one, they are usually available where CDs and DVDs are sold, and even some "dollar" stores have them for a buck or two.

In that case of a dirty lens, why would abootable CD be detected okay but not a bootable DVD? Perhaps because the data on a DVD is stored much closer together on the disk than it is on a DVD.

If that doesn't help, the drive may be defective, and in that case you need to replace it.

If other regular bootable DVDs, not copies, are detected as bootable fine.....
If the DVD you are using is NOT a regular DVD, it's a copy of a Windows DVD, then if it is NOT on a DVD-R disk, it may NOT be detected properly as being bootable if it was made in a different burner drive.
