Toshiba sataellite c855d-s5320 says no bootable device upon start up

I bought the same computer from Walmart for my daughter for Christmas. I have had to send it in three times to have the hard drive fixed as it showed the same error that you were getting. I was very mad as the first time I had to pay $25 to have them ship me the box to send it in to them. I also tried at first to return it back to Walmart but was told it was to late and I would have to go through Toshiba. I just received it back again today. They have had to replace the hard drive three times. This is ridiculous as I have had several other computers and laptops and have never had to have a hard drive replaced before. I told them I was not paying the last two times to send it in for repair as it should never of had to go to them the first time. The girl did send me the box free the last two times but honestly I think they should just give me a whole new computer as I think these ones are lemons! I cannot believe a brand new computer would need to have a hard drive replaced 3 times in 5 months! The girl advised me if it had to go back again they would probably finally do something. I sure hope your is working better then mine.
