I have used this thread to fix all issues I have with booting Windows 7 except one. I have googled like crazy for a solution to this problem but I haven't even come across someone with the same issue. Everytime I try to start my computer using the power button I get the following message: ""reboot and select proper boot device" Or, when I have booting from network enabled in the bios it does that instead. I've tried all kinds of combinations of settings in the bios (which has limited configuration options), I've updated to the newest bios firmware, I've reset it to the manufacturing settings. I've also disabled hibernating. If I restart by chosing "restart" in Windows it restarts completely normally (and really quickly now that I've used this thread and the thread on speeding up the boot process), recognizes the hard drive and boots from it immediately. If I shut down the computer or set it to hibernate and have to start it up with the power-button I get the "reboot and select proper boot device"-message. When I use the power button I can only get the computer to boot to windows by entering the bios and changing ANY setting -- after that it starts up normally (and the bios always recognizes the hard-drive and lists it wherever I left it in the boot-order last time I was in the bios). No other buttons works, except F2 which gets me to the bios. None of the other F-buttons, the esc-buttons or any other buttons I've tried do ANYTHING at all once I've pressed the power-button and the computer starts up. Since I've tried to change every setting I can change in the bios the only two options I can think of are problems with the hardware or in the windows settings. My laptop is Asus ul30a and my OS is Windows 7 64bit. Any suggestions on how I can find out the cause of this power-button-induced problem using the methods from this post? Or any other method?
