Serious errors were found while checking the disk drive for /

Ubuntu 14.04 LTS trusty tahr versi stable sudah rilis di bulan april kemarin, sedikit menemukan masalah pasca instalasi via wubi, term disini laptop run dual boot os. apakah masalah itu?, ubuntu tidak berjalan dengan normal/abnormal boot. Muncul pesan

Serious errors were found while checking the disk drive for /

Nah berikut adalah solusi nya: 

press [I] to ignore, press [S] to skip mounting and press [M] to mount manually

masalah terselesaikan dengan langkah berikut
1. in windows boot manager, select Ubuntu .
2. press any key and go in GUN Grub2 menu.
3. you can press "e" to edit GRUB2 boot entry. you need changing GRUB2 boot entry from "ro" to "rw",



e.g
linux /boot/vmlinuz-3.13.0-24-generic root=UUID=AAC884AC1F144321 loop=/ubuntu/disks/root.disk ro quiet splash $vt_handoff

to
linux /boot/vmlinuz-3.13.0-24-generic root=UUID=AAC884AC1F144321 loop=/ubuntu/disks/root.disk rw quiet splash $vt_handoff


press "F10", you can boot in ubuntu 14.04.
and you can fix GRUB2 boot entry:

sudo nano /etc/grub.d/10_lupin

e.g:

${rel_dirname}/${basename} root=${LINUX_HOST_DEVICE} 

loop=${loop_file_relative} ro ${args}

to: 

${rel_dirname}/${basename} root=${LINUX_HOST_DEVICE} 

loop=${loop_file_relative} rw ${args}

Re-generate GRUB2 boot entry

sudo update-grub 

FINISH!!!
