I just did in my laptop , but when i am trying to boot from usb to my old computer i got error , what setting should i choose in bios ? USB-FDD , USB-HDD , USB-LAN , USB-ZIP , USB-CDROM ?
As Bum Soo said unplug other devices like, CD/DVD ROM, external HDD (hard drive) Must.
USB-HDD, USB-CD/ROM. 1 correct from both of these. Kindly try one by one. Pick setting through bios under >
USB-CDROM and save changes. now plug in Bootable usb and restart pc/laptop, keep press Boot key during it restart, now Click > USB-CDROM < and see if it run installation. If not? then it is definitely > USB-HDD < go to bios again and pick >
USB-HDD < save changes and do the same i explained in upper lines. Thanks!
Addional: It's definetely one workable from USB-HDD - USB-CD/ROM so try both and see which would work. 75% sure it's USB-CD/ROM. or else search on google with your laptop/Pc manufactured company name & model name. You will get official website where you may see all the explaination about booting function and it's use related to your laptop/system.
