My asus laptop doesnot show boot sequence in bios option

[pathak_bibek2007]

I want to install windows 7 on my Asus laptop but as I select bios option, I cannot select BOOT priority. But the options are shown

What model?
Have you observed the options on the screen? Have you checked the User Guide?

If you can't change boot order in BIOS, usually you can still select a different boot device at startup, without going into BIOS, by pressing a different key (or combination, again, specified on the opening screen, and in the User Guide).
