Hi i have a Compaq Presario Laptop , and i lost the original CD drive some time ago , so i bought this new(as in not used before, it looks like an old model) IBM USB CD-RW drive , it works fine when ubuntu is loaded ,but when it try to boot from the Hardy Heron CD , or any of my bootable CDs , the computer just ignores the CD , in BIOS , i don't see such anything such as: USB CD DRIVE in the boot sequence list , there's just the ATAPI CD/DVD something ... Do i need to update my BIOS ? How to do so if yes ? my Bios is a Phoenix . Thank You guys !
