Hi I have a HP 2133 notbook that does not have an internal DVD drive. I needed to reinstall Windows XP so I used an external DVD drive to do this. The CD booted fine and I chose to reinstall windows through the Windows set up consol. The hard drive was formatted using NTFS (quick) but when the machine rebooted to begin installing the OS it comes up with the error message "Erro loading operating system". The notebook recognises the DVD drive so that's not the problem. Can anyone help me with this?
