RT, 前一阵子因为给c盘分区的原因导致了这个现象.....从网上各种扒搂发帖各种尝试都不管用, 到最后作业都没弄出来... 终于放弃了, 从windows里把原ubuntu的未分配空间分了个盘就当删除ubuntu了. 那么我现在该怎么做才能删除grub呢？ 尝试过原装windows系统u盘内命令提示符运行bootrec.exe /fixmbr, 显示的是操作完成, 但重启之后一点效果也没有, 还是显示grub>.... 在线求解......

grub>
When GRUB 2 is unable to boot or display the GRUB 2 menu the system will be left at a GRUB 2 terminal if possible. If the system boots to the grub> prompt, the usual modules and commands are normally available. The user may need to manually load modules using the insmod [module] command before some commands will work.

The configuration file (grub.cfg) may be missing, misnamed, or corrupted.

最简单的办法，搞个pe工具箱，进pe修复启动，一般都会自带启动修复工具，或者把系统刻盘，再修复系统启动。这个只能在win下面操作了。
