Windows 7: [Urgent] PC restarts after booting from DVD

Hi guys,

I wanted to upgrade XP to 7, I've upgraded it partially when in XP. So now XP is no more, and I only have to boot from the DVD.

But now I have the problem:
Every time I insert the Windows 7 DVD the pc says
"Press any key to boot from CD or DVD..." (as normal),
When I've pressed the any key, the PC does absolutely nothing and just restarts.

After that, I fiddled around in my BIOS, "turned a few switches", made a copy on a fresh DVD. Now when I insert the DVD, the PC says:

Press any key to boot from CD or DVD...
When I've pressed the any key the PC says:
Press any key to boot from CD or DVD...
When I've pressed the any key the PC does absolutely nothing, no reboot, no loading, no next screen, no nothing, altough the underscore flashes trougout the whole time.



I've cleaned the pc from the inside, (with a vacuumcleaner), opened the CD/DVD player, blowed air in it so the dust could come out... Nothing works...

Could someone please tell what's wrong?
Is it the DVD? Is it the DVD-player? Is it the motherboard? Is it because my keyboard does not have the any key? Is het something wrong with my BIOS settings?


Help,

Just to confirm, the original DVD you tried is a real original Microsoft windows 7 DVD and not a copy?

toxications,

Now I assume the name is not an indication of the source of the problems.

My suggestion is:
SSD / HDD : Optimize for Windows Reinstallation - Windows 7 Forums
Clean Install Windows 7 - Windows 7 Forums

Are all drives showing BIOS?

Can you post your specs.

Can another bootable CD or DVD boot correctly at prompt?

If so, where did you get Windows 7? Burn it using ImgBurn at 4X speed with Verify which never fails if the ISO is good. Look for the word "bootable" in text at left after loading ISO.

Do you have a 4gb+ flash stick to try booting to install Windows 7? If so, follow one of these methods to write the ISO to it: Windows 7 USB/DVD Download Tool

Try also running installer from XP to see if it will install.

Make sure no USB devices are hanging off the machine too.

The original disc was to severely damaged (cats), the PC couldn't read the disc, only my laptop (brandnew) could read it. So I was forced copy it.

Great idea, now I just need the pc to read the installdisc.

Yes, all the drives are there in the BIOS, even a floppy disk I don't even have. I'll fill in the system specs later when I have the time.

So, was the copy made from the already scratched disk or a brand new Win 7 disk?

Did you do a 1 to 1 copy (Copy Disk) or did you just move the files to a blank cd and burnt the disk?

It appears that your CD is not a bootable CD and therein lies the problem.
