The boot failed ending in a BusyBox splashscreen :
Busybox v1.1.3 (debian 1:1.1.3-5ubuntu12) Built in shell (ash) Enter 'help' for a list of built-commands
The problem is relatively simple, the hard drive screw up a little bit.
Many suggestions found on the net suggested to boot in Windows, do a check of the disk and re-boot.
That's nice if you have Windows installed somewhere.
For who, like me, doesn't have Windows nor even think about to install it, here a simple workaround.
- Look for a live Linux distro and boot the PC with it
I used Knoppix.
- Look for GParted (Disk partition utility)
- In GParted look the drive (hard drive), select it, choose "check"
- When the check is finished, reboot normally
It should work.
It worked for me anyway :-)
