Hi. I'm trying to install ubuntu 12.04 using USB. After downloading the ISO file, I used pendrive software to make bootable USB drive, but after restarting my computer, I encounter this error:

Unknown keyword in configuration file: ...

I need your help as soon as possible.
Thanks.

Did you MD5 test the ISO you put on the USB?

No. How should I do that?

A simple google search would have brought up this result:

https://help.ubuntu.com/community/HowToMD5SUM

I used winMd5sum to check my ISO file with the Ubuntu hashes, but it failed with the error "MD5 check sums are different!"

I downloaded the ubuntu-desktop-64amd.iso file from the Ubuntu official website. I'm confused. Please help me.

If the hashes are different then the file is corrupted

Just redownload the file and try again.

SOLVED : Everyone! Just download torrent file to be sure that file is not corrupted.

MD5 testing exists for a reason, please MD5 test in future and it saves a lot of time and hassle.

Thanks
