I am new to archlinux. I am using live usb for archlinux. When I booted it said not a COM32R image. I explored on Google, used Tab and choose have64 and then it booted.

Now I am not able to login I used password root but it's not accepting. I also used startx but nothing happened. I am using archlinux-2014.06.01-dual iso downloaded from archlinux website.

I see the the following Arch Linux Menu after boot-up

 Boot Arch Linux (x86_64)(NBD)
 Boot Arch Linux (x86_64)(NFS)
 Boot Arch Linux (x86_64)(HTTP)
 Boot Arch Linux (i686)(NBD)
 Boot Arch Linux (i686)(NFS)
 Boot Arch Linux (i686)(HTTP)
 Boot Existing OS

I Choose First one and fourth one (NBD) for live boot and i am having the problem mentioned above.
