win 8.1 install issue

installing 8.1 on my pc and i am at the point where it says copying windows files (0%). It is at that point for 10 mins. Is that normal? if not, what could be causing it?

thx

ps... I will say this use to be a dual boot pc of 7 and 8.1 so i had to change bios around to get both on there i think it had legacy option or something like that. Should i reset bios to default and see if that solves it and then install again?

It's been 20 mins and nothing yet. Should i wait an hour before doing anything? plz help.

thx

PS. bios looks something like this:

---> UEFI boot sources
-----------usb floppy/cd
-----------usb hard drive
-----------ATAPI CD-ROM
.......Legacy boot sources
--------ATAPi cd-rom
--------USB FLOPPY/CD
-----------ATAPI cd-rom
-----hard drive
-----------sata1
-----Network controller (atheros boot agent)
