请教用VMWare在物理分区装Redhat Enterprise问题

eternight

是用硬盘上的ISO装到物理分区上

安装一切正常，启动虚拟机后屏幕显示
CLIENT MAC ADDR: XXXXX.....
PXE-E53: No boot filename received
PXE-M0F: Exiting Intel PXE ROM
Operation System not found

同时VMWare跳出窗口：
No bootable CD, floppy or hard disk was detected.
To install an operating system, insert a bootable CD or floppy and restart the virtual machine by clicking the Reset button.

请问这是什么缘故？
我试过Grub装在MBR和物理分区里都不行。
物理分区是逻辑分区会不会有问题？
