I have a laptop for 1 year. I have on it: 1 Win 7 64 bit 2(!) Linux Ubuntu 10.10- one on a shrinked partition from D:\ (this OS is not working) and another: installed one on Windows, without making any partitions for it. In the last few weeks, I have encountered these symptoms: -I/O errors from all over the drive, mass software and system crashes, slowed down OS -As I finally managed to save my data, the OS crashed, so it won't load( Windows symbol doesn't starts) Willing to format entirely my HDD SATA WD5000BEVT I tryed multiple boot CDs.None of them launched, even if I specified to boot from CD/DVD ROM. Only few maintenance disks were able launch, inlcuding the HDDs maintenance DOS CD, but it doens't sees my Drive. Other partition disks just simply stuck in their loading process, and are useless. I have tried with bootable USB drive, supposing that my DVDROM is nasty, neither that worked.If I disable all of other boot options, and leave just CD/DVD ROM, than comes with a message: REboot and Select proper Boot device or Insert Boot Media in selected Boot device... I suppose that I have either a Boot Virus, or my HDD is dying. Can anyone help me somehow?
