No Bootable device found error

Hi,

I bought a new Dell Inspiron 5547 from US.From past ten days its sayings No Bootable device found error while starting.I've checked BIOS setting HDD is not detected.But after few hours I'm able to open it.After few minutes the disk space reaches to maximum due to svchost.exe process.

Please suggest how to get it fixed.Now I've moved to India.How can I claim my warranty or free service in India.

Thanks.
