what is computer boot sector
If I understand your question correctly then the answer is the BIOS (Basic Input Output System). It checks that all of the hardware in your computer is functioning correctly and the settings for said hardware (example: the boot order - whether to boot from the HDD or a disk in the disk drive).
If the computer is off the boot is called a cold boot or initial startup.If the computer is on the boot is called a warm boot or restart.
Dual-boot and Multiple-Boot are pretty much synonymous.
it is looking to see where the Operating System is located and making sure all of the hardware is working correctly
A computer boot process is the procedure of starting a computer from scratch, culminating in the loading of and operating system.
No - a cold boot is starting the computer by switching it on. Re-starting an already running computer is a 'warm boot'.
its what tell the computer what to boot first, it can be anything choosen by the bios, if you go into the bios you can change the boot order.
Removing the CMOS battery will not prevent the computer from turning on, it will only cause the information in the CMOS RAM to be lost (while the computer is turned off). When you turn on the computer after the CMOS battery has been removed, while it will turn on it will most likely not boot the OS correctly but will stop in the BIOS and require you to completely setup the CMOS parameters again before you can tell it to continue..
Turn it on when it is completely off.
