Data recovery after OS failure
Despite the constantly improving reliability of operating systems, users still sometimes face OS failures. An operating system may fail due to the corruption of its logical structure (caused by either computer viruses or human errors) or due to the damage of a storage on which it is installed (caused by hardware failures, system breakdowns, sudden power failure, etc.). A corrupted operating system is unable to boot: it will try to start and may progress to a certain point, freeze and not boot any further or stop with a blue screen or error message.
Note: the messages "Invalid System Disk" or "Please Insert Bootable Media", especially when the machine doesn't report the presence of the hard disk drive, are a sign of a disk failure instead of an OS issue. In this case, it's strongly recommended to take the disk to data recovery specialists for the examination.
Depending on the peculiarities of your case, you can choose one of the following solutions:
- Using a different computer: one should remove the hard drive and connecting it to another PC for further recovery.
- Using an Emergency Recovery CD: one can perform the data recovery procedure on the same computer using an Emergency Recovery CD
