Hi,I'm a debian newbie,
 	
I just installed ArchLinux and chose encrypted LUKS

i got an error like:

 ERROR: Failed to open encryption mapping: The device /dev/sda2 is not a LUKS volume and the crypto= parameter was not specified.

blkid:
/dev/sdb1: LABEL="boot" UUID="32037003-e7f8-4ebb-a5f8-259077c86eac" TYPE="ext2" 
/dev/sdb2: UUID="82f95717-7bf3-43b0-82c0-31472e016e96" TYPE="crypto_LUKS"
So what can I do now? How can I boot my system?
Please help,

Den
