I just bought an Acer Aspire 5336 Series from my friend, the laptop worked flawless, but, he had a lot of programs, video editing, music editing, games, ect. I decided I wanted to do a restore back to factory settings, well, about halfway through the restore, it got an error, now when I try to boot from the HDD, it says a file is missing from System32. It tells me to use the repair disk to fix it. I put the repair disc on a USB, and tried to boot it up, I get message saying "Error Loading Operating System". I Struggled with it for a bit before I decided to try to load Ubuntu on to it instead, I put Ubuntu on a USB stick, went to boot, same error. I also get the same error with Windows XP, I tried to format the entire drive, but the formatting program gets the same error when booted from. I am confused at this point. The thing is I have a Desktop and now this laptop, the DVD Drive in the Desktop doesn't work, that is why I have been using the USB Stick. Could the fact that I am using a USB be the problem? Rather then a CD/DVD? I need some help, I am pretty desperate at this point, thanks. :frown:
