Ubuntu – “Kernel panic – not syncing: No init found. Try passing init = option to kernel” after installing Ubuntu with UEFI

I decided to install Ubuntu 12.04 LTS second system with windows 7, UEFI. Made a LiveUSB, downloaded, started the installation.

The installer showed four sections, one for efi already existed (windows loader seems named, 100 MB), the other three, ntfs. One of them I erased (of course, partition with windows I saved), and created two partitions – swap and /. The installation was successful, no errors. But after the reboot comes to grub, the choice of Windows 7 again returns to the grub, when choosing Ubuntu – gives black screen with error:

[1.310472] Kernel panic – not syncing: No init found. Try passing init = option to kernel. See Linux Documentation / init.txt for guidance.

Besides, now will not ship LiveUSB.
