Hi all, I'm hoping I can get a clear perspective on an issue with my computer. I have a HP laptop and it got bumped into a hard surface which I think has messed it up. When I turn it on it says that it cannot find the hard disk. BIOS does load and says it cannot detect hard disk when I look for it. As a side test, I have linux on a usb flash drive that I booted and it worked fine (linux works). Is the hard drive damaged and/or lost? How can I fix it and find out what happened? Thank you in advance!
