ok so i have a problem ive made a usb bootable bt2f flash drive but for some reason my laptop does not support usb flash drive booting

so i though id go with the next best thing..... a hard drive installation but heres where the problem is

i do the unmounting and start qtparted it says theres a error but thats because of my cd hardware..... so i go stright to hda1(i think thats what it is) for my hard drive thats have window installed on it....but when i try to create partitions for the back track install and boot it says that my hard drive is READ ONLY

so if anyone knows how i can change this do tell

or if you could point me in the right direction because ive googled it and couldnt find anything
