Hi, I'm having some trouble with my computer. I have Windows XP installed, but I wanna install Ubuntu and Vista (only because of DX10 of course). I've tried to boot from the Vista DVD, and it recognizes it as a bootable disc but after it asks "press any key to boot from disc" and I press a key, the screen just turns black. However, when I updated the firmware for my NEC ND-2500A drive, it does run the installation, but extremely slowly. Every step in the installation process takes 15 mins+ to load. The Ubuntu installation comes as far as the screen where you choose whether to install, verify the disc contents and so on. However clicking on any of these will load the kernel, but the screen will turn black after that. So, it sounds like the problem was the DVD drive right? It's not though, because I just bought a SATA DVD drive today (the old one was IDE) which have the same problem. So, the problem is not the drive or the IDE/SATA channels. What do you think?
