[SOLVED] Encryption hook doesn't prompt for key

I'm trying to dual boot an encrypted arch (64bit luks encryption without lvm) and windows 8 on uefi. Everything installs pretty smoothly until it tries to decrypt the root partition, it doesn't prompt for the passphrase. Using a g55vw laptop, there's a wiki page for it apparently which I've been trying to follow. When I search for related problems most people solve it by moving the encrypt hook around but I've found that doesn't help
(yes I run mkinitpio -p linux).

My output when grub loads arch:

:: running early hook [udev]
:: running hook [udev]
:: Triggering uevents...
:: running hook [keymap]
:: loading keymap . . . done
:: running hook [encrypt]
Waiting 10 seconds for device /dev/mapper/root ...

/etc/default/grub

/etc/mkinitcpio.conf

You need to use "cryptdevice=/dev/sda2:root" instead of "cryptsetup=/dev/sda2:root".
