view story

http://askubuntu.com – I have tried to install Ubuntu 12.10 numerous times, I previously tried the older version 11 something... anyway, I have finished downloading the files and it sped through the other stages at a fast pace but now it has been 2 days and the green installation bar has not moved a bit! it's stuck on round about Half and then some way, This keeps on happening! and I have re-tried many times, this was the only time I left it overnight, Although I think my laptop went to sleep, so that might of did something. I'd appreciate some help! It'd be nice, but anyway... I want to make sure I still have Windo (HowTos)
