红帽全球峰会5.2. 引导装载程序
GRUB 2
Red Hat Enterprise Linux 7.0 使用新的引导装载程序 GRUB 2，该程序比其前任 GRUB 更具鲁棒性、更方便也更强大，后者是 Red Hat Enterprise Linux 6 使用的引导装载程序。GRUB 2 提供大量的功能和改进，最主要的有：
- 除 64 位 Intel 和 AMD 架构外，GRUB 2 现在还支持更广泛的平台，包括 PowerPC。
- GRUB 2 支持额外的固件类型，其中包括 BIOS、EFI 和 OpenFireware。
- 除支持主引导记录（MBR）分区表外，GRUB 2 还支持 GUID 分区表（GPT）。
- 除 Linux 文件系统外，GRUB 2 还支持非 Linux 文件系统，比如苹果的
扩展分层文件系统（HFS+）和微软的NTFS文件系统。
