Can not find operating system

**MILINTICA** · 06-04-2009

I have an HP Pavilion dv9950ef, and I sometimes, often at first startup, a message saying it can not find the OS, namely VISTA. Then i restart my pc one again but same problem. I tested the SD and DDR via utility bios HP, he said that everything is ok.

Can anyone help me ?

Thanks

Check the Hard disk, and yes the BIOS battery too. If you get the continues beeps, Check the RAM. remove them, and fix them properly. Check the power code and the data cable of the hard disk are fixed properly. Check your Monitor light turns green, and your monitor is getting the signal from your CPU. if not, you have to fix the VGA card properly.

Open the PC and a component can change to blow the warranty. If you consider the wear SAV waits a bit before changing anything.

Maybe the disk that has your operating system is no longer recognized as the "Master Boot" or the "Master Boot Partition" disk.

Most hard drives come with software that allows you to set a designate a small portion of the hard drive to indicate whether that drive has all the stuff that needs to be loaded into memory, and run.

Errors within the NTFS can cause this issue to happen. if you can run CMD when Windows does boot, or from a BartPE disk, type chkdsk /f and see if this helps.
