电脑爆炸拉~急！

我装了LINUX后，那个GRUB为什么不能正常引导了啊？
一开机就出现：GRUB Version 0.93 (639k lower/260800k upper memory)
[Minimal Bash -like line editing is supportted.For the first word,TAB lists possible command completions.Anywhere else TAB list the possible completionsof adevice /filename.]
GRUB>;_   ←系统提示符
按了TAB后出现的命令如下：Possible commands are :backguound blocklist boot cat chainloader clear cmp color configfile debug displayapm embed find foreground fstest geometry halt help hide impsprobe
initrd install ioprobe kernel lock makeactive wap md5crypt module modulerrounzip pager partnew parttype password pause read reboot root rootnoverif sawedefaule serial setkey setup splashimage terminal terminfo testload testvbe unhide uppermem vbeprobe
后来我把硬盘重新分区了这个还在啊？要怎么把它弄掉啊？急！
