Click if this solves your problem!
Problem Description:
Error 105 Partition starts on wrong boundary
Error 105
Cause(s) of the problem
The hard-disk partition table contains erroneous values. PartitionMagic / ServerMagic / VolumeManager expects FAT, NTFS, and HPFS partitions to begin and end on the boundaries used by FDISK. If they do not, the disk may be partially corrupted. In this circumstance, if PartitionMagic were to make any modifications it might cause loss of data. Therefore, PartitionMagic / ServerMagic / VolumeManager refuses to recognize any of the hard disk?s partitions.
