Yesterday we were trying to make the laptop we just bought a dual-boot laptop using Windows XP and Windows Vista together. For that, we created the required setup CD with required drivers. When we tried to boot from the CD, we could not do it. We checked the boot order in BIOS, it was correctly set, but still, it was not using CD/DVD to boot.

We got the fix through BIOS upgrade, lets see in details how to to a BIOS upgrade.

Fix:

Several laptops have several ways of BIOS upgrade. Some of them may require a boot CD / floppy / USB-drive to upgrade the BIOS version. Some others like HP Pavallion also provide windows based utility which you can download and run, to upgrade the BIOS. Below is a screen-shot for the utility which we used.

This upgrade utility will compare the present BIOS version with the newly available BIOS version and will install the new BIOS version, and will restart your computer. After booting up, the new BIOS version will come into effect and will fix any bugs which were there in the previous BIOS version.

After making the BIOS upgrade on our laptop, we were able to boot it from the bootable CD / DVD drive. See your laptop manufacturer’s web-site for latest version of BIOS and other hardware drivers.
