我可以使用生成 uefi iso
mkisofs -quiet -R -J -T -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e images/efiboot.img -no-emul-boot -c isolinux/boot.cat -b isolinux/isolinux.bin -o UEFI.iso .
以下命令确认其为 EFI 介质
dumpet -i UEFI.iso
Validation Entry:
Header Indicator: 0x01 (Validation Entry)

Section Header Entry:

Boot Catalog Section Entry:

但是当选择这个 iso 作为启动介质时,它就无法启动
UEFI.iso 的内容
ls /mnt/EFI/BOOT/
BOOTX64.conf BOOTX64.efi splash.xpm.gz TRANS.TBL
ls /mnt/图像
efiboot.img efidisk.img install.img product.img pxeboot TRANS.TBL
知道可能是什么问题。在此 uefi 服务器上定期启动 redhat 6.5 iso
