As mentioned above, the access keys for the BIOS of each model will be different and the BIOS interface may be different, but the steps below will apply to computer models.
Step 1:
Once we have successfully accessed the BIOS, click on the Boot menu tab. You will see quite a few options as follows:
- Hard Drive: Windows will proceed to boot from the hard drive on the computer. This is the default boot. After reinstalling Windows, we need to go back to proceed with the setup for this option.
- CD-ROM Drive: boot from a CD or DVD drive.
- Removable Devices: use USB or external hard drive to boot. Note to the user, some models of this option will display as External Drive, Removable Device or USB.
Step 2:
Normally, the machine will boot into CD or USB first to check if there are any installation devices such as Windows installation disc, Hirent Boot disc or not.
Next is the boot order on the hard drive to run the operating system. In case the user proceeds to install win or ghost the computer needs to change the default order above.
Case 1:
The boot order will always default to Removable Devices. We will use the up and down arrows to change the boot, select the first boot location and press Enter to select.
Case 2:
With the order on the left, we use the arrow on the keyboard to select. We go to the first option and press the left or right arrow key, or press Enter to appear the menu, then choose where to boot first.
Case 3:
The interface has a Boot Device Priority section, users will access it and use the arrows to select the part to boot in the 1st Boot Device.
When you don't see the option for USB or External Device, we will look for the Boot Configuration section, the External Device Boot section changes Disabled to Enabled.
Finally save and press the F10 key to exit the BIOS.
