These day ,Imet a problem.
One day,when I start my PC,I found it enter into a grub command line.Then I used the fdisk /mbr in dos to unintall grub.And then reinstall the Fc5 x86_64.After a few use ,I met the same problem. I did use the FC-5-x86_64-rescuecd.iso.And I found that /boot/grub/menu.lst was blank.
I have try some methods but it did't help.
Firstly, I donīt know if fedora creates a whole new boot partition and installs the kernel there, and mounts the directory or if it just instals the kernel in /boot directory (anyone else know the answer to this?)
Regardless if you used the rescue disc, are you sure that you didnīt look in the rescue disks grub/menu.lst file?
When you boot into the rescue disc Show me the output of:
I find it surprising that something is writing over your menu.lst because.. that shouldnīt happen.
I recorded the imformation,I hope you can help me:
/proc on/proc type proc(rw)
/dev on/dev type tmpfs(rw)
/dev/pts on/dev/pts type devpts(rw)
/sys on/sys type sysfs(rw)
none on /tmp type ramfs(rw)
none on /tmp type/ramfs type ramfs(rw)
/proc/bus/usb on/proc/bus/usb type usbfs(rw)
/tmp/loop0 on/mnt/runtime type squashfs(ro)
/selinux on/selinux type selinuxfs(rw)
/dev/sda9 on/mnt/sysimage type ext3(rw,data=ordered)
/tmp/proc on/mnt/sysimage/proc type proc(rw)
/tmp/sys on /mnt/sysimage/sys type sysfs(rw)
/dev on /mnt/sysimage/dev type tmpfs(rw)
/selinux on/mnt/sysimage/selinux type selinuxfs(rw)
That's the imformation,can you tell me what to do?
Are you running another operating system alongside grub?
Booting from the FC5 disc
Entering the linux resuce mode F(5)
At the prompt: type chroot /mnt/sysimage
At the prompt that follows type grub-install --recheck
Then restart and see if your grub configuration has been fixed.
Sorry, I should clarify further:
Boot from the FC5 disc
Enter the linux resuce mode F(5)
At the first prompt where it asks you for a particular type of kernel, just use the default by pressing enter.
At the system (not boot) prompt: type chroot /mnt/sysimage
At the system prompt that follows type grub-install --recheck
Then restart and see if your grub configuration has been fix
