I'm trying to install Linux Ubuntu on my computer (which is an Acer Aspire 5040) but everytime I try to set the boot priority when I start my computer up, it turns itself off and I have to plug my external hard drive in for it to boot Windows XPLast time I tried it, it came up with a message saying "there is not enough virtual memory." Or something like that and I'm not actually too sure what that means to be honest lol. I'm trying to boot Linux from a live CD but.. Y'know, it's not working.Any suggestions?xxI have 512mb of RAM so I don't think it's that..But thanks anyway
