Once I was stuck in a problem, such that a new laptop hard disk was undetected by operating system though it’s detected on BIOS. This problem occurred when I tried to re-partition the HDD that has Windows Vista running, with third party partition software. Later I found that those re-partitioned disk were undetected by Operating System. So I tried to format with bootable Windows XP/Windows Vista and other bootable CD but unable to solve. So I searched in the internet for the solution and found this software which solved the problem.
