In general, if the OS pre-installed on your computer doesn't boot nothing else will either. No Linux distribution can fix your broken computer and blaming your problems on BIOS, UEFI or Secure Boot just to get attention won't fix things either. Secure Boot, when enabled, will not let you boot anything that isn't signed, including removable media. Fedora 17 isn't signed so SB wasn't enabled. Expecting GRUB2 to work when your Windows bootloader didn't work isn't logical. Like it or not PC's are designed for Windows. If Windows doesn't work on it, take it back. Very likely the harddrive had problems, this would explain it not booting and the install running slow as it retried when getting errors from the drive.
