I have an acer inspire laptop. My ex-roommate had installed and partioned both windows 7 and ubuntu linux onto it so I could switch back and forth between operating systems because I'm too lazy to always have to code out what I want the laptop to do. After 3 months the laptop is not detecting either operating system. When I try to boot up the ubuntu disk it leaves me with the following message: uncomppressing linux... ok, booting the kernel. [4294668.025000] PCI: Cannot allocate resource regin 0 of device 0000:00:1f.6 It won't even allow me to run the disk as a live system like the book states I can do before deciding to install. How do I get the ubuntu disk to boot up linux so it will actually read an operating system? The book says I don't need to have an operating system on the laptop before installing linux. Is this true? And simply what do I do next?
