Hi, My Dell Inspirion N4010 working smoothly, just next morning when I switch on NO Hard drive detected and go to PXE ROM msg and not boot due to no OS found. BIOS version I think needs to be updated as shows A08 where current version is A13. but since this BIOS file is EXE not even able to run from DOS. Please suggest what to do ASAP. Thanks and Regards, Santosh (santosh.ghosh9999@gmail.com)
