I have a computer that came with Windows 8 preinstalled. I want to boot from a CD, in this case Hiren's Boot CD. However Windows 8 doesn't seem to like this.
I have tried pressing F8, ESC, F12 and so on. I read online that Windows 8 can boot in 200ms, so that it might not even be possible to boot from a Live CD before Windows loads.
I would like to know how to boot from a CD before Windows loads, if possible. If not possible, how to boot from the Live CD after Windows loads.
After further tinkering I was able to get to the BIOS using F2. I changed the settings to boot from CD first, and I even disabled "Secure Boot". The computer seems to ignore these settings and booted Windows anyway. I was also able to access the "Boot Menu" using F12.
I choose "CD drive". It did a "media check" on the CD even though I disabled Secure Boot, and the check failed; again it booted Windows after that!
