My office just bought an Acer Aspire 603G running Windows 8.1. Found out the software we need to run isn't compatible with 8.1 yet. They advised me to install a dual operating system, either XP or 7 Pro and go from there. Sounds good in theory. Problem is, when I try to boot from a Windows XP cd, or any cd for that matter, it won't boot. It just bypasses and goes straight to the regular operating system of 8.1. I have gone into the bios, disabled secure boot, enabled the boot menu, and changed the boot options to go to the cd first and still nothing. When I restart, I can hit a key to bring up the boot menu but the only option is Windows Boot Manager. I contacted Acer, who kept telling me to enable/disable CSM Launch and I kept telling them that I don't even have that anywhere on my boot options! When I go into the boot tab, all I can do is change the boot order and view the priorities, that's all. No CSM. They had me update the BIOS, still nothing. Then they said they would have to bump me up to a level 2 tech which isn't available until sometime tomorrow. Anyone here have any suggestions or should I just throw it out the window?
