13.04: Kernel panic - not syncing: No init found

I know this question has been asked several times on this forum, but none of the answers given worked for me.

Tonight I did an install of Ubuntu 13.04 on a brand new Acer Aspire laptop. I formatted the complete harddisk, removing the existing windows 8 partitions. Installation had no problems. After rebooting the system hangs and says: "Kernel panic - not syncing: No init found. Try passing init= option to kernel".

I am able to boot the liveUSB.

What I have tried

• Complete re-install of the system. Same error appears


• Started LiveUSB, mounted filesystem, restarted. Same error.


• Started LiveUSB, tried sudo fsck /dev/sdb1, mounted filesystem, restarted. Same error.

I am quite new to Ubuntu, what next steps can I take? How can I pass init= option to the kernel?

Thank you very much in advance!

I tried a lot of things, it apparently was no mistake during the installation, since I tried it many times. I think it is a hardware/driver issue in 13.04.

I finally solved the issue by installing Ubuntu 12.04 LTS, which worked immediately. Maybe this is helpful for somebody facing the same problem.
