The necessity to change the system boot sequence is one of the most common tasks and one should use BIOS settings to solve it. If you install these parameters correctly, you can speed up the loading and prevent from possible problems.
First Boot Device (1st Boot Device)
This parameter sets the drive for the first system booting. If it is impossible to boot from this drive, a computer refers to those which are set in the parameters “Second Boot Device” and “Third Boot Device”. Using these parameters, you can configure any desired sequence of operating system research for loading.
Depending on the version of BIOS, the following items may be used as values of the parameters “First/Second/Third Boot Device”:
- the names of drives that may be connected to a motherboard. The following designations are the most common:
- HDD-0/1/2/3 (IDE-0/1/2/3) – a hard disk connected to one of IDE-channels;
- CDROM (CD/DVD);
- USB FDD, USB CDROM, USB HDD, USB-ZIP – one of devices with USB-interface;
- SCSI – a device with SCSI-interface;
- LAN (Network) – loading via LAN Network;
- Disabled (None) – no devices for loading;
- the names of de facto detected drives. In this case the parameter value would comply with the name of the device;
- Removable – a loading from removable drive. If there is more than one drive, use the parameter “Removable Device Priority (Removable Drives)”;
- Hard Disk – a loading from the hard disk. If there is more than one hard disk in a system, select necessary drive by using the parameter “Hard Disk Boot Priority (Hard Disk Drives)”;
- CDROM (CD/DVD) – a loading from CDROM. A desired device is selected by using the parameter “CDROM Boot Priority (CDROM Drives)”;
- Disabled – no device is selected for loading.
Install the first hard disk boot for constant operation, i.e. select HDD-0 (IDE-0) or similar to it for the First Boot Device parameter. In this case you will no longer need to check if there are media in the floppy disk drives or CD/DVD drives.
