求助：suse 11.2 无法启动及重新安装

lagrandeur

事情是这样的。前天我的linux系统崩溃了，我先试图用dvd自带的修复程序修复系统，显示如下信息:
1. partition table of sdb is lost. （选择略过，sdb是我电脑上的空白硬盘，原先我的linux系统安装在sda上面)
2. activate sda1(Swap). (Yes)
3. not found packages: /var/lib/rpm/Filemd5s. (rebuilt & succeeded)
4. initrd modules missing: the file /etc/sysconfig/kernel contains a list of modules to add to the initial RAM disk by calling mkinitrd. Yast is missing the following modules: jbd2, mbcache & ext4. (repair failed: Root device (sda2) not found)
5. boot loader error detected. (repair succeeded)
然后我重新启动电脑，在屏幕显示suse的启动界面以后变为黑屏。

现在我想重装系统，我点了“import mount points"按钮以后，安装程序提示:
A previous system with the following mounting points was detected: /etc/fstab found on /dev/sda2:

/dev/sda1 swap
/dev/sda2 /
/dev/sda3 /home

是不是说明我原来在sda上的文件还能找回来？是否应该按照如下方式重装系统以恢复原来的文件？多谢。

/dev/sda1 2.01GB (no_F_sign_here) linux_swap swap swap
/dev/sda2 20.0GB (no_F_sign_here) linux_native Ext4 /
/dev/sda3 909.51GB (no_F_sign_here) linux_native Ext4 /home
