I just got a 1 1/2 yr old windows 8 Gateway 500 gb, 2.2 gh pentium, 4 gb ram laptop. Probably made a mistake. Girl I bought it from said the sound just quit when she fired it up to check it out before shipping it. The audio jack is broken. I think I can use a usb speaker, as the computer says it is still working when I tested it with a program I found in control panel audio. I fired it up, changed profile to mine, and went to restart it so I could do some partitioning and add another operating system to dual boot. At first it wouldn't shut down, for over an hour as it was configuring updates, then it couldn't install updates and was reconfiguring. After an hour and a half I turned it off anyway. The next several times I tried to start I got the same message. I finally got into BIOS (had to click f12 instead of f8, or f2) and set it to bood from dvd, thinking I could look at a few things with a live linux disk. Tried to reboot and got a message saying security won't allow booting that way. I've since gotten into windows 8, installed avast (I don't really want the norton on it) and am now running it. Is there a way to disable the security so I can boot from a dvd? Control panel install programs show it was set up on Dec 27, 2012 I was planning on dual booting and running both so I could have my files on 2 partitions with different operating systems in case of malware. I'm just learning 8, I had an XP computer that still worked great. I guess I'm still a little upset about having to get rid of a perfectly good computer. Actually after dithering awhile I put linux on it, but still want to keep some of my windows programs. Not sure what other info I should send. Thanks for the help.
