Boot order

From MEPIS Documentation Wiki

Jump to: navigation, search


The most common problem is that your computer's BIOS 'boot order' (or sequence) is not set up to boot from the CD-ROM drive by default for security reasons. You can change the BIOS boot order quite easily until you have run your Live CD or installation CD and then change it back again if you are worried about security. If you want convenience as opposed to security, you can leave it set to boot from the CD drive before the hard drive, ready for next time.

As you start your computer there should be some information there somewhere telling you what key to press to enter your computer's BIOS.

How to change the order
