Hi, Tom
I've attached the FSTAB to the bottom of my prior pastebin post:
http://pastebin.com/m50e45f6a
swapoff -a gives> Speeduke prompt
mount -a gives> [ 982.179.186] VFS: Can't find ext3 filesystem on
dev dm-0,
mount: wrong fs type,bad option,bad superblock
on /dev/mapper/Speeduke-_swap, missing codepage etc...
mount: mount point /home/jack/XP_VDI does not exist
(+ more similar)
swapon -s gives> Filename Type Size Used Priority (no other data)
swapoff -a gives> Speeduke prompt
swapon -s gives> (same as previous swapon -s)
'Hope that helps!!
Jack
