A week ago I bought Lenovo E531 with Windows 8, but I don't like this operating system. I used to use Win XP. I downloaded Ubuntu 12.10, followed all the instruction how to create an bootable USB stick, but my laptop can't boot Ubuntu yet. Can You help me please!

Since your laptop came with Windows 8, it probably has a feature called UEFI secure boot enabled, which can cause problems when installing Ubuntu. Follow the instructions here to disable UEFI secure boot:
Create a LiveDVD or LiveUSB of Ubuntu (>=12.04.2) 64bit.
In your BIOS, disable QuickBoot/FastBoot and Intel Smart Response Technology (SRT). If you have Windows8, also disable FastStartup.
Boot your PC using the LiveDVD or LiveUSB and choose "Try Ubuntu". If you get a Secure boot or signature error, you may wish to disable SecureBoot as described here, then retry to boot the disk.
Install Ubuntu from the Live CD/DVD or Live USB in the usual manner, then reboot the PC.
If the PC does not load Ubuntu (but instead loads Windows, for example, as in Bug #1050940), or if the Windows entry in the GRUB 2 menu does not boot Windows (see Bug #1024383), boot your PC using the Live CD/DVD or Live USB and choose "Try Ubuntu" once again. When the live session has loaded, run Boot-Repair (see link for details). When Boot-Repair loads, click on the "Recommended repair" button, and write on a paper the URL (paste.ubuntu.com/XXXXXX/) that will appear. Then reboot the pc. Do not run Boot-Repair unless you have problems booting the computer; the expression "if it ain't broke, don't fix it" applies to this tool.

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference.– TimAug 22, 2014 at 19:29
