I have a HP Laptop that the bios set a password power on. Took me 3Hrs to get in the back door to reset the password, then the file system would not boot on a partition so I got to the partition and run chkdsk and for 10hrs its been repairing. the partition is 250gb and it saying that its repairing invalid security id with default security id for file #####. If this doesn't work replacing HDD OS/Recovery Partition system image and other software, drivers updates and network what do you think this should cost including whats all ready been done. John
