Ubuntu Server Installation Killed My Netbook

So I have an HP Mini netbook that was previously used as my main laptop. I have since upgraded to a better system, but my need for it returned as my old server, a Sony VAIO laptop, experienced a hard drive failure. It was old anyways so I decided to use the netbook instead. It didn't have a CD drive so I had to put the ISO for Unbuntu Server (32-Bit) on a flash drive. The installation succeeded, but when it came time to restart to boot for the first time, the laptop would get to the HP splash screen but would hang at this screen. Keyboard input didn't help either. Couldn't change boot settings and couldn't enter BIOS. I took it apart and hooked up the HDD to my desktop computer. The drive spun up but it wasn't detected by Windows. Also the netbook experienced the same issue even without its hard drive. Please help me resolve this issue as I need a server to run my website. Thanks!
