Bootable CD that reads files

hi guys i want to upgrade my bios cause my old one was bugged so my battary isnt charging .

ok so from start my computer say that i have battery and she is avaible and charging but it stuck on 0%

now to upgrade bios i need 10% of the battery and ac connected, so its all good just my battry dosent charge so im stuck at 0% .

now for my question i want to create a bootable cd that countain my new bios that i have downloaded from dell support .

but when i try do that the cd is bootable but i cant access the file that i burned on him (bios update)
actually i cant access the directory that the file is in , all i can see is the boot files of the image i have burned with nero.

thanks for helpers (:


my system specs:
dell inspiron n5010
i7 8gb ram 500gb hdd
no floppy .

i know but this problem is common and lots of dell users got it cause dell is **** so i want to fix it but i dont know how =\

im searching for hours i can see their answers but the problem is that i cant do that cause their answers are:
1. buy a new battery (hell no) myne is new .
2. upgrade bios (cant not enough battary precentage 10%) needed.

Too bad you're not close, I could lend you the battery from my Dell Inspiron N5010.
