Last night, i was installing dsl. I chose installing grub. i didn't know when it suddenly my knoppix has gone from grub. I didn't replaced knoppix with dsl. My Knoppix was installed on sda4, and dsl on sda3. Can knoppix be restored again? How? Pleeeasseeeeee help me...

Hi,

It sounds to me like when installing DSL, you overwrote your existing GRUB configuration. What needs to be done now is to edit the GRUB config file to include an option for your other distro.

By the way, you didn't screw up, since you would have had to perform these steps either way: if you hadn't overwritten the GRUB configuration, you'd be wondering why DSL didn't show up in the menu, and I'd be telling you to perform these same steps

Boot into DSL, and (as root) edit the file under /boot/grub/menu.lst. You should be able to essentially copy the whole block for DSL to create a new entry for Knoppix. The only real difference should be your partition identifier numbers (keep in mind GRUB counts from 0).

There's one caveat with this setup: Your GRUB configuration now resides under DSL's /boot/grub/ directory, and from the sounds of it, Knoppix is your main distro. You can of course boot into Knoppix, edit the same file there, and reinstall GRUB so that it uses the Knoppix configuration. This is only an issue if you are considering removing DSL from your system, in which case you would delete the configuration GRUB is currently using, resulting in (if I recall correctly) a GRUB error 17. Cheers, best of luck,

ok, i'll try it. Thanks for Felix

Ok, i did it. But there are several questions that i want to ask.
I try to edit /boot/grub/menu.lst in dsl. I simply copy from dsl, i wrote
"Knoppix
kernel /boot/linux24 root=/dev/hda4 quiet vga=normal noacpi noapm nodma noscsi frugal"

then i boot it. I choose knoppix. The result was
"Booting Knoppix
kernel /boot/linux24 root=/dev/hda4 quiet vga=normal noacpi noapm nodma noscsi frugal"
(linux-bz Image, setup 0x1400, size=0xf17f7)
uncompressing Linux.... Ok, booting the kernel.

Error....
(lot of text, it said many had missed)

then it enter in knoppix non GUI(text only) and some error
root@(none)#
root@(none)#nano /boot/grub/menu.lst

then i tried to copy boot menu in here and paste it at dsl.

title Knoppix

root (hd0,3)

kernel /boot/vmlinuz-2.6.17 root=/dev/sda4 ro ramdisk_size=100000 lang=us apm=power_off nomce vga=791

initrd /boot/initrd.img

savedefault
boot

And it works!

My questions is... dsl and knoppix use same bootloader, Grub, so why its configuration different?
