I'm trying to install Ubuntu 64-bit on my Lenovo E530 with i5 3210M CPU. According to this information: It is officially supported.

However, when I try to boot from USB flash drive, I get the 'kernel image is corrupt or invalid' message. I'm using UNetBootin to create a live USB and I've tried both 13.04 and 12.04.2 ISOs from official website (torrent downloads).

I've managed to successfully boot with 13.04 32-bit, however. This is what i get from

cat /proc/cpuinfo

so the processor appears to be detected correctly. However, when i do

uname -p

it shows 'i686'.

Any idea what is wrong here?

UEFI Secure Boot is disabled by the way.

Have you verified your download using the hashes? Please post the output of md5sum ubuntu-something.iso (use the proper filename) and include both the command/filename and the output in your question. The message "kernel image is corrupt or invalid" you see is because it is corrupt or invalid. – gertvdijk Jul 23 '13 at 18:58

I've managed to successfully install and boot 13.04 64-bit using "Try Ubuntu without installing" mode of UnetBootin (e.g. booted using this mode, selected 'Install Ubuntu', and then booted from hard drive). Hope this would be helpful to anyone having similar problem.
