硬盘安装分区出错！求助！

arbor

把iso文件放在C盘，grub、vmlinuz、initrd文件都在D盘，用grub从DOS下启动后进入安装过程，前面都很顺利，到了分区阶段，不管是手工分区还是自动分区，分区结束后先提示：
Warning！
The kernel was unable to re-read the partition table on /dev/ide/host0/bus0/target0/lun0/disc (Device or resource busy).This means Linux won't know anything nothing about the modifications you make until you reboot.You should reboot your computer before doing anything with /dev/ide/host0/bus0/target0/lun0/disc.

按继续按钮后显示正在创建分区，然后显示创建文件系统失败。返回分区步骤。

Alt +F2 显示提示中的目录下面只有disc、part1、part2、part5这样几个文件，错误出在哪里？
