Information device, storage medium and initial state restoration method
View Patent ↗An information device has a storage medium storing information items which includes a first program provided on a first partition, a second program and data provided on a second partition to restore the first program on the first partition to a predetermined state, a boot block which causes system activation from one of the first partition and the second partition, and an active-partition switching program which indicates, to the boot block, one of the first and second partitions. An input/output system activates the active-partition switching program when a specific operation is performed. The active-partition switching program indicates to the boot block that system activation is to be executed from the second partition.
1. A computer comprising:
a processor;
an input device;
a storage medium storing a basic input/output system (BIOS);
a hard disk drive (HDD) comprising a hard disk, the hard disk comprising a first partition, a second partition, and a boot block storage section,
the first partition storing an operating system (OS) to be executed by the processor,
the second partition storing data for use in restoring the OS to a predetermined state for system recovery, and storing restoration software to execute processing to restore the OS to the predetermined state for system recovery by using the data, and
the boot block storage section storing a boot block having partition information indicating which one of the first partition and the second partition is an active partition; and
a storage section storing an active-partition switching program to be activated by the BIOS upon depressing a specific key of the input device and to change the partition information of the boot block so that the second partition becomes an active partition and the first partition becomes an inactive partition,
the BIOS causing the boot block to activate one of the OS stored in the first partition and the restoration software stored in the second partition, based on the partition information.
2. The computer according to claim 1 , wherein the hard disk comprises the storage section storing the active-partition switching program, the storage section being different from the first partition and the second partition.
3. The computer according to claim 1 , wherein the storage section further stores a copy of the active-partition switching program.
4. The computer according to claim 1 , wherein the active-partition switching program, when activated, changes the partition information of the boot block so that system activation is executed from the second partition.
5. The computer according to claim 1 , wherein the restoration software, after having restored the OS for system recovery, changes the partition information of the boot block so that the first partition becomes an active partition and the second partition becomes an inactive partition.
