@wanchai - I've seen this error before. Have you tried adding "rootdelay= 8" to your boot parameters?
As for myself, I'm getting a lot of Glibc errors. I burned the ISO. Could it be the disk? I did md5sum though and everything matched. One of the error I was able to write down is: "missing /usr/lib/x86_64-linux-gnu/libapt-pkg.so.4.12". I checked the folder and the file is there. There were more errors pertaining to /usr/lib/x86_64-linux-gnu folder but I could not catch them all (too quick for my eyes) but I saw something about resolve.conf and a lot of GLIBC 2.14, GLIBC 2.15 version error messages. Sorry, could not give you guys the exact error. Tried looking for it on every log files under /var/log but could not find it.
Another thing I noticed is that under /usr/lib folder, I see a few links to a file that has a "broken link".
Other minor issues that I noticed. (I was able to manually fix myself)
- during installation, it did not find the other OS installed on my hard drive. So I had to edit the grub.cfg myself
- I installed LMDE on sda2 but on grub.cfg it is on sda7
