How to force ubuntu to boot at any cost?

Question

linux

I rebooted and some kind of "kaka" with one disk, when booting Ubuntu stopped at the question:

Blah blah blah brother, error on the mounted disk, press F - to fix, S - to continue. Until you press it, I won’t start any further blah blah blah

I had to come here to where the server is at one in the morning, because you can’t get remote access. There is some READY example of how to debug the boot to the state: If the percent, memory and disk with the system and boot sector = ok, it will boot and skip everything else. The rest can be repaired via SSH.
PS: bubunta 14.04 + XEN hypervisor (it seems to rule both the bootloader and the system for virtual machines)

Answer 2

Boot from livecd, if necessary, chroot and mount and update the bootloader, or just cut out what the errors are from fstab.

Answer 4

Press the S key with a match (just kidding).
But in general, this particular problem, if I remember correctly, is solved by adding your disks to rc.local.
In roughly this form:
And this, I may say stupidity, but in general, is it not the gui who throws out such things? In the sense that it stops the system from starting when it fails.
