hey so like 5 or so days ago i tried installing windows 7, i got this windows 7 disc from my laptop which i made for a recovery (acer recommended it) so i tried installing it, it was fine up until it said setup is installing devices and got stuck at 49% and then i left it for the night and i woke up the next moring i turned off my computer and turned it back on i got an error about i have to reinstall windows 7 or something and then it restarts when i press okay, i tried installing windows xp from a disc but all it does is it says booting from disc..... and then it comes up with the windows 7 thing and then says the error again and restarts i have no clue what to do and i dont have a working computer anymore help!
