(I'm using a Phenoix BIOS on a 32 bit dell inspiron 530)

well my os has failed im using windows vista on a dell inspiron 530 hdd,im trying to boot ubuntu from a usb stick but when i do it just tells me boot error??

my bios boot priority is set to removable then hard disk then cd rom

and my removable device priority is set too - USB-ZIP0 : Make of USB 1GB

can anyone please help,should i change my bios settings? or should i just try with a cd

btw is their any other way besides using ubuntu that i can retrieve my date from my hdd(windows vista) and safe mode is not an option as i cannot access that either

my computer knowledge is only ok(if anyone could explain it a little simpler) thanks this means alot
