Due to the virus attack the computer will not boot from the hard drive
and FDISK displays a partition of unknown type. Active@ Partition
Recovery also shows the partition to be "Unknown" type and
does not allow previewing and scanning.
When a partition type is displayed as "Unknown", it is likely

computer becomes un-responsive and will not start from the hard drive.
The solution is simple if you have previously created a backup of the
Master Boot Record and partition information prior to the disaster
event. Using Active@ Partition Recovery you can easily recover and
Master Boot Record from a floppy disk.
Boot the machine using a system recovery floppy and run Active@
Partition Recovery, restoring the Master Boot Record from the
NOTE: IT IS STRONGLY ADVISED TO MAKE MBR AND
PARTITION TABLE BACKUP EVERY TIME THE COMPUTER CONFIGURATION IS CHANGED
(SUCH AS ADDING OR REMOVING HARD DRIVES, PARTITIONS, LOGICAL DRIVES).
Please see Backing Up MBR Data in the
previous chapter for details.
