How to Fix a Dell Computer that Says Error Loading Operating System?
I recently bought a second-hand Dell computer and used it for about one week, then I encountered a boot error. The message shows 'Error loading operating system', and I don't know what it means. Can someone tell me what to do to fix this? Thanks for your help!
