Automatic alternating bootable storage devices between different kinds of boot files
Backup for a computer system that automatically creates files that will allow the user the choice of which storage device with a bootable operating system to boot. An embodiment may automatically detect if the operating system is any of a plurality of versions of Windows XP or Windows Vista and create the appropriate files identifying the storage devices containing bootable operating system of the right types for use with these operating systems.
1. A system, comprising:
a personal computer system containing at least one system storage device and at least one additional storage device;
said personal computing system having any of a plurality of operating systems;
said personal computing system running a startup sequence that uses a first file to specify an identification of bootable devices attached to said personal computer system; and
said personal computer system running a first software application using said operating system that, when called with the identification of said at least one additional storage device, operates to determine which of a plurality of different operating systems is being used, determines which of a plurality of files defines the information in said first file, and to automatically alter said first file such that the at least one additional storage device is listed in said first file as an additional bootable storage device hosting a backed up operating system.
2. The system of claim 1 where said first software application backs up said operating system, and allows starting said personal computer system using said backed up operating system.
3. A system as in claim 1 , wherein said operating system is a windowing operating system, and said first file is a boot.ini file.
4. A system as in claim 1 , wherein said operating system is a windowing operating system, and said first file is a BCD file.
5. A method, comprising:
operating a personal computer system using an operating system;
running a startup sequence that uses a first file to specify an identification of at least one bootable storage device attached to said personal computer system;
starting said personal computer system using a first boot device; and
a first software application determining a new bootable device wherein resides at least one backed up and bootable operating system, and responsive to said determining, determining which of a plurality of different operating systems is being used, and determining which of a plurality of files defines the information in said first file, and automatically altering said first file such that the at least one bootable storage device is listed in said first file as an additional bootable storage device.
6. The method of claim 5 where said first software application backs up said operating system, and allows starting said personal computer system using the backed up operating system, and specifies said bootable storage device that backs up the operating system in said first file.
7. A method as in claim 5 , wherein said operating system is a windowing operating system, and said first file is a boot.ini file.
8. A method as in claim 5 , wherein said operating system is a windowing operating system, and said first file is a BCD file.
