请教，关于烧写开机LOGO的问题

今天烧写开机LOGO，但是烧写完成之后出现如下错误：
Press [ENTER] to launch image stored on boot media, or [SPACE] to enter boot monitor.

Initiating image launch in 1 seconds.
Launching image from boot media ...
OEMPlatformInit: IMAGE_TYPE_RAMIMAGE
+=OEMVerifyMemory+ dwStartAddr:0x80200000  dwLength:0x4
RAM image 0xa 0x80200003
+=OEMVerifyMemory+ dwStartAddr:0x80201000  dwLength:0x4
RAM image 0xa 0x80201003
OpenPartition: Invalid MBR.  Cannot open existing partition 0x21.
ERROR: ReadOSImageFromBootMedia: Failed to open existing partition.
OEMPlatformInit ERROR: Failed to load kernel region into RAM.
系统为无法启动，不知为何？谢谢

你重新烧写把。
记得烧写LOGO完，要用 b 来保护一下

按楼上说的方法~不行~开机闪一下全白，，随后就是六道杠了
