I tried to install AVG but it showed some error saying it can't be installed.. Writing of some file is denied..I tried installing FSECURE Dos version,i was able to boot in dos using bootable disk,now comes another problem,My HDD is SATA..it is not recognized by DOS.. Now what should i do frenz.. Pls help..
