安装11.10dvd版的出错啦。。请大大们帮下忙

[coconut1]

用的硬盘安装。。。重启电脑后选择安装ubuntu之后就出现了(initramfs) /scripts/casper-premount/20iso_scan:line 46:can't open /dev/sdb:No medium found

Could not find the ISO /ubuntu-11.04-desktop-i386.iso
This could also happen if the file system is not clean because of an operating
system crash,an interrupted boot process,an improper shutdown,or unplugging
of a removable device without first unmounting or ejecting it. To fix this,
simply reboot into Windows, let it fully start,log in,run 'chkdsk /r',then
gracefulty shut down and reboot back into Windows. After this you should be
able to reboot again and resume the installation.

这是怎么回事啊。。。郁闷啊，我之前安装过64位版的之后卸载了。。。重新装这个就出现问题了

没找到硬盘或者盘符不对，u盘安装很便捷的说

grub的配置文件怎样写的啊？而且明明是硬盘安装，怎么有个sdb的？
