I've been reinstalling my system today, cause I was trying to clear up all the rubbish pilling inside. I was at the last step of reinstalling when I accidentally off the laptop. When I on the laptop again, it shows, "an operating system wasn't found........Ctrl+Alt+Del" After following the instruction to press Ctrl+Alt+Del, it comes back to the same page with the same message. I went in to the setup utility page according to the instructions on the web, but I don't know how to continue because I don't have a recovery disk or USB or anything at all. I can't even access another functioning PC. And I won't be able to purchase a recovery disk too. Please help it's really urgent! Thank you!
