Cyril, I used nano to open the syslog file and searched for "/proc". The search results where an error was indicated was:
netcfg[5237]: INFO: Could not find valid BOOTIF= entry in /proc/cmdline A search for "mount" and found: main-menu[361]: (process:4352): mount: mounting /dev/sda on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sdb on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sdb on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda1 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda1 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda10 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda10 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda11 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda11 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda2 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda2 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda5 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda5 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda6 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda6 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda7 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda7 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda8 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda8 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda9 on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument main-menu[361]: (process:4352): mount: mounting /dev/sda9 on /media failed: Invalid $ main-menu[361]: (process:4352): mount: mounting /dev/sda on /media failed: Invalid $ main-menu[361]: (process:4352): umount: can't umount /media: Invalid argument This is followed be a repeat of the same above.
