中国DOS联盟

系统有xp 原先的ubuntu8.04升级出了毛病.想重装一个ubuntu 在网上找了一下..找到了ubuntu-9.10-alternate-i386.iso 用grub4dos安装成功.但重启能进ubuntu9.10进不了xp 我日常的工作都在xp下进行. 只好在dos下执行fdisk/mbr 找回了xp 但是ubuntu进不了.不知道在grub4dos下ubuntu9.10的启动代码是什么.能前的ubuntu8.04是用grub4dos引导的.有哪位大侠有代码给发一下.有办法也行.谢谢.

这回的问题，个人理解为三个神打架了。

一个NT的引导，一个GRUB，一个ubuntu……

重点是你是想用GRUB来引导其他两个系统么？

去研究下。顺便希望知道的朋友也来给个法子……

在 Grub4DOS 加上 Linux Ubuntu 9.1 的選項

title Start LINUX Ubuntu 9.10
find --set-root /grub/core.img
kernel /grub/core.img
boot

root=(hda,6)
kernel (hda,6)/boot/vmlinuz-2.6.31-14-generic root=UUID=8e76bd24-037a-4036-989e-a2d32e570736 ro single
initrd (hda,6)/boot/initrd.img-2.6.31-14-generic

先更新您的GRUB4DOS……

# title 启动 Ubuntu 9.10 Linux 2.6.31-14 (有BOOT独立分区)
# find --set-root --ignore-floppies --ignore-cd /grub/core.img
# kernel /grub/core.img
# boot

# title 启动 Ubuntu 9.10 Linux 2.6.31-14 (无BOOT独立分区)
# find --set-root --ignore-floppies --ignore-cd /boot/grub/core.img
# kernel /boot/grub/core.img
# boot

# 如果系统文件为 Ext4 格式您可以试试下面的，注意您的内核，后加rootfstype=ext4：
# kernel /vmlinuz-2.6.31-14-generic root=UUID=dd9d9f5d-0c46-4e32-874a-505bdce82ece ro quiet splash rootfstype=ext4
# initrd /initrd.img-2.6.31-14-generic
# quiet
