Completely reinstalling Windows 7 Starter on Samung N150 Netbook

Im trying to reinstall Windows 7 starter on my friends samsung netbook. The computer wont boot up at all. Ive tried using the system recovery feature but that doesnt work, it syas files are missing. I tried running in Safe Mode but the it crashes before the operating system loads. A few other processes display the message 'operating system not found'.

My only choice is to delete everything thats ont he hard drive and format it, then reinstall the operating system. Thing is, she hasnt got any copy of Windows 7 Starter, neither on a disk or optical drive. If I were able to get a copy of the OS, how wouold i go about deleting everything on the hard drive and reinstalling it?

Ive been goin round in circles for a looong time and am getting nowhere so any help from any geniuses on here would be infinitly appreciated :) thanks guys.

Tap the F4 Key at the Samsung logo when you first power on the computer.

ive gone into the system recovery, nothing happens once the samsung logo comes up, it just stays on that page for ages saying 'please wait...' and does nothing. there is no disk drive so i cant use recovery disks, its a netbook

im not fussy about recovering any data because there was nothing on there that i need to keep. i just want to be able to get into Windows anduse the computer

To do this you need a disk or a working Recovery Partition.

Check the hard drive with the manufacturer's diagnostic tools.

Tap F8 at reboot to see if you have Repair Console on Advanced Boot Tools menu. If so boot in to run Startup Repair up to 3 separate time with reboots to see if you can Repair Win7.

If not on F8, create a System REpair CD on another Win7 machine with same bit-rate in Backup Center. Boot it to do the Repairs at least 3 times, which should automate System Restore - but try it manually anyway if necessary.

You can copy out your files Copy & Paste - in Windows Recovery Console then find any Win7 retail installer, unlock all versions if necessary, to reinstall clean Win7 using these steps to get a perfect reinstall: Reinstalling Windows 7

thanks guys, much appreciate the help.

for starters, it doesnt boot up to the windows desktop so anything that requires that is a no-go.
anything i do will have to be done through the setup menus. ive tried countless times using F4 and trying to run the system recovery but it just freezes and doesnt do anything, just displays the Smasung logo and does nothing.

as far as what i did to cause the problems; im not sure. its a friends netbook who doesnt have the faintest idea about computers. she said it just crashed one day so just switched it off, then switched it back on and it wouldnt load windows.

can u clarify what the COA sticker is? there are 2 stickers, one with the netbook model number and serial number on it, and another one with the microsoft logo on it, however the details have been rubbed off through wear so they cannot be read.

i really just want to delete everything off the hard drive (remember i cant do anything through windows, i need to do it through the setup menus or something similar) and reinstall windows then.

Thanks a bunch guys
