Some of you may or may not be aware about UEFI, the new BIOS for new computers that have been out for about 1 or 2 years. They have secure boot enforced by friendly Microsoft OEM hardware makers, so a project like this priatebox live CD may have boot problems.
Old computers have the old BIOS so thats fine.
New computers have UEFI. Some have Enforced Secure boot. Some have UEFI with Secure Boot on/off.
1) UEFI with Secure Boot on/off. Easy, just turn off, save.
2) Enforced Secure boot. Piratebox will fail to boot. Either ask maker to add on/off feature, or get in bed with Microsoft to get some keys.
