re-installing windows from CD

I am running 32bit windows starter on a samsung N150 notebook, I am thinking about buying a new installation CD, will it install over my existing faulty windows 7 or will I have to remove programs first,,simple answers please for a simple person

It is not necessary to buy another copy of Win7 since you own Starter version on that PC for its life and are entitled to reinstall it as often as you want.

Simply download the latest official installation media for Win7 Home Premium x86 SP1 English Official ISO download, run the eicfg removal tool to unlock all versions, burn to disk using ImgBurn 2.5.7.0 - FileHippo.com at 4x speed or write to bootable flash stick using UltraISO Software To Create Bootable USB Flash Drive. Then boot the disk or stick, select Starter version during the reinstall.

Everything else needed to get and keep a perfect Clean Reinstall - Factory OEM Windows 7 is here in the blue link. It compiles everything that must be backed up from the old install, how to do the install itself, and how to set it up including the tools, methods and optimizations which have worked best in ten of thousands of installs we've directly helped with here.

Thanks for the solutions,,, the main problem is that it is not booting,, without me pressing the Enter key, followed by the windows key,,, I know I should have start up repair installed,,, but cant find it anywhere at all

Tap the F8 key or Use the disk I provided above to boot into System Recovery Options to run Startup Repair a few times. What does it report?

Can you remember what might have caused the failure? If unsure and you want to try everything possible to start it use the Failure to Start tutorial under picture below. At any time you can skip to rescuing your files and reinstalling using the Win7 disk.

Thanks for your help, I will follow your other intructions now, cant paste the is the report, but it didnt solve the prob.
I done a sytem recovery when I got it from a friend as it had loads of his data on,, after that it just stopped booting

I'd strongly consider doing a Clean Reinstall - Factory OEM Windows 7 if one hasn't been done on the PC yet. This is a vastly superior install to the factory bloatware so that you can experience Win7 in its native perfect state without the crapware and duplicate utilities which interfere with better versions built into the OS.

If you stick with the steps, tools and methods in the the blue link tutorial above you'll get and keep a perfect install for as long as you do.

Thanks for all your time and advice,, I am going away for 3 days and will definitley try what you have suggested on my return,,will keep you updated
