Windows 10 does not fit on a CD. Perhasp you mean DVD.
The DVD reader drive  might be dirty.
The DVD itself might have fingerprints or other grime that prevents perfedt reading.
Look this over:

Go down to tha part about cleaning the disc surface with a cleaning kit or damp clean cotton cloth. Take care not to scratch the surfaxe of the disc.
You  can make the cloth damp with a litle bit of water. A small bit of alcohol can help remove stuborn dirt.

You can also clean a bad disc with toothpaste, but first try just the damp cloth. The toothkpaste method is extreme and has to be done very crefully.

To restore a damaged CD, apply a dot of non-gel formulat toothpaste to a cotton cloth and rub in a straight line from the center of the CD outward, covering any scratches. Rinse off the toothpaste with water.

The method is good for either CD or DVD disds.

Is this a legal Windows installation CD? Do you have a valid legal license?

How to download a Windows 10 ISO file

Everyone should know how to reinstall Windows 10, because you never know when a random mishap or malware will render your PC helpless. Put a copy of Windows 10 on an optical disc as an ISO file, or on a USB key drive, and you'll be ready if your PC needs to start over.
Assuming you have a legitimate Windows 10 license, start by going to Microsoft's Windows 10 download site...

You may want to try again with a fresh copy on a USB stick. You will need a good 8 or 16 GB USB flash drive.

Tacking on to Salmon Trout's post, is this an original retail CD or a copy?

This is valid dvd and i have serial key on it also.
I just want to ask u that  was able to install it but now os is booting. I tried windows 7 then, it booted the time i installed it, but not thereafter. Sometimes sticking at windows logo, sometime giving errors that some hardware or software change might be the problem, and tried to chkdsk it simply dont start.
Could it be a hard disk issue, if so how to check it.

Noman,
To do diagnostics you might need some more tools.
A. You need either another PC that works
or
B. A good spare hard drive. Even a 20 GB can be used for testing.

Ifit were me, I would take a good sparee samll hard drive and do a full install of Windows 10 on the spare hard drive. I would make notes of what steps I took and note if some hardware did not install right.
From my own experience, there are some things I  can not use untill I  get the basic install finished, My HP printer interfereces with USB things untill I get Windows installed. My second monitor does not work right untill I finish the install.

Also, the add-in video card might not work right unill yoou first get Windows fully installed. And it is very annohying whne Windows wants to do an update before you finihe and fully test the instalation. So I  force auto-update off untill I get all the base install finished.

In general, I have have good results from buhying used cheap small hard drives from reputable eBay vendors For testing purpose, you don't need a brand new hard drive, in my opinion. In takes me less time to do a new fresh install rather tahn try to fix  a system taht does not repair itself.

Maybe this could be of some help.

If chkdsk won't run your HDD is likely dead...

If chkdsk won't run your HDD is likely dead...

The most likely explanation, given all the symptoms.
