Latest computers permits you to install two or more OS on single hardware. This configuration is known as Multi-boot (generally called dual-boot). You can use features of different OS and can work alone on them. In some conditions, where you use dual-boot configuration with Linux operating system, you may face serious issues of system metdata structure corruption that leads to serious data loss. At this situation, it become essential to go for Linux data recovery to get your mission-critical data back.
In a practical situation, you might come across following error message when you try to install Fedora Core to make your system dual-boot with any other Linux distribution:
The partition table on device is corrupted. To make new partitions it must be initialized, causing the loss of all data on this drive.
In such conditions, the partitions still boot properly. But under the System Tools-> Hardware browser, you just see a large green bar for hard drive. It does not show the hard drive volumes. When you run fdisk to perform data recovery Linux, you get following result:
Disk /dev/hdc: 100.0 GB, 100030242816 bytes
16 heads, 63 sectors/track, 193821 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Boot Start End Blocks Id System
Partition 1 does not end on cylinder boundary.
Partition 2 does not end on cylinder boundary.
Partition table entries are not in disk order
Root cause
As sated in the first error message, this problem generally occurs due to corruption to the partition table. Partition table is the most important data structure of Linux OS that stores critical information about hard drive partitions. This information is required by the OS to access hard drive partitions.
In case of damage to the partition table, all of your critical data gets deleted and you require Linux recovery to get your data back. This is possible through Linux data recovery software.
These applications use advanced scanning algorithms to systematically scan the damaged hard drive and recover lost data from it. They have simple and interactive GUI to allow.
