I've been an apple and windows-user all my life, and now I bought me an netbook (acer one aspire 722) and wanted to install Ubuntu (I have no experiance with any linux systems at all). I read a lot of forums but haven't found my problem anywhere so I hope to find some help here.

I need to install Ubuntu from an USB drive. I downloaded unetbootin to creat a bootable USB drive with my mac. I createt a bootable Ubuntu (12.04) version on that and plugged it into my netbook. On my netbook I changed the bootorder so it should start from USB first but I simply get a lot of text (e.g.: EXT2-fs (sda1): error: ext2_lookup: deleted inode referenced: ....) but no installation or even an installion screen started. What did I wrong?

I would say your usb is corrupt, did you retry to create a bootable usb? – Gerhard Burger Dec 5 '12 at 8:23
I have tried it with a USB key with 12.10 amd64 and i386, and also with USB connected CD drive, and it won't boot to these. 12.04 on USB connected CD will boot. – user128800 Feb 5 '13 at 18:59
