I have a new Sony Vaio and when I turn on my laptop, it goes no further than the initial screen and then says 'Operating System Not Found' and lets me go no further. Any idea what the problem could be?? Cheers Ross

If it is new then return as faulty, taking it apart to check hdd is seated will void the warranty.................

Hi, It's not brand new - got it early December so have put my iTunes updates on ot for a month which os loads... It's still under warranty but do you know if there's anything which can be done? Ross

Since you just received the computer and it is covered under the warranty, I would deal directly with the manufacturer (so as not to void any warranties). Sony appears to have several support options on their site. If you go to this link, you will find a section for computers/Vaio which offers you live chat options, traditional call in, etc. Good Luck. http://esupport.sony.com/US/perl/su...

hi i have a acer aspire that runs windows vista and i have allways had an issue with my start up by this i mean windows vista appears twice i have allways chosen the second option and it has allways worked but this past week it has not workeed at all and yesterday i turned it on and it will not let me get any further than the acer start up screen after that it comes up with Missing operating system_ and the underscore then flashes. i am extremely worried seeing as all of my essays and coursework peices are on my hard drive please can anyone let me know how to resolve this problem and tell me if my hard drive has been wiped or not please reply thank you

Hi, Apologies, I'm not very technical but I called Sony when I had this issue and they walked me through the possible options but this basically means that your computer can't find Vista and that's not too good. They did need to replace my HDD unfortunately but if your computer's still under warranty, you should be ok? Sorry that it's not good news (well, my experience wasn't anyway). Cheers Ross
