I can't boot into windows. My BIOS screen comes on but it wont actually boot windows from my hard-drive. I understand that a file is corrupted - a file in my root directory that assists with the bootup of windows. The meesage that comes up says the following- word-for-word: Windows could not start because the following file is missing or corrupt: <windows root>\system32\hal.dll So it is and application extension somewhere in my root directory that is corrupted. My question is the following: How do i fix this so i can boot into windows again? I was going to format my drive in a few days time but i need to get some files off the computer before i do. It is essential that i get these files back as it will be hard to get hold of them again. My BIOS details are AMIBIOS K7S5A Release- Made By American Megatrends My OS is windows Xp home edition. Hope someone here can help me with this! Thanks.
