what is grub menu entry after frugal instalation?
« on: October 12, 2014, 09:45:46 AM »
hello,
please help. i installed tc on a hard disk partition. but when i boot the computer it shows only lubuntu and xp boot entries. how do i add tiny core boot entry?
 i searched in forums and wikis and it so confusing. i know that all i have to do is to edit grub menu entry in lubuntu. but how?
 thanks!

You might find this post helpful

Obviously changing the specific parameters to suit your system install
eg  depending on your specific install you might need to change  " nitrd /boot/rootfs-530.gz /boot/modules-3813.gz "  to  " initrd /boot/core.gz "   along with the install path, UUID's and --set=root values

You need to use a text editor with root (administrator) privileges to edit the boot.cfg - I guess it would be easiest to use lubuntu to do this.

Maybe you could paste the contents of boot.cfg in this thread to make it easier to explain how to modify it?

Is the uuid you mention above the correct one for your hardware (what are you booting tinycore from)?
Have you renamed vmlinuz, rootfs.gz and modules.gz or are you using the default names?

copying verbatim wasn't exactly the intention I had here..


something like this might be a better starting point

menuentry "TC-5" {
search --no-floppy --fs-uuid --set=root c24280e8-8a74-4de9-817b-fecf26dce8d6
linux /boot/vmlinuz loglevel=3
initrd /boot/core.gz
}

(replace the above id with your hardware id if this one is not correct)

if you run into problems, you might find also this site useful

i tried what you suggested
menuentry "TC-5" {
search --no-floppy --fs-uuid --set=root c24280e8-8a74-4de9-817b-fecf26dce8d6
linux /boot/vmlinuz loglevel=3
initrd /boot/core.gz
}
then update grub,  NOT working.
my uuid must be the one from sda1 where tiny core is installed?

This is the UUID you provided

thanks for answering,
 here is my boot.cfg    tiny core is in sda1, lubuntu in sda2 and win7 in sda3. tiny core is core plus current pc is 32 my UUID for sda1 is UUID="c24280e8-8a74-4de9-817b-fecf26dce8d6

}

then update grub,  NOT working.
If you've manually edited the grub.cfg file then there is nothing accomplished by update grub command

check the path to vmlinuz and core.gz?

they are expected to be found in
/sda1/boot/

if not then where are they?  then you'll need to modify the grub entry to suit

I think the update-grub command will only probe hard drives for those OSes which grub is aware of and then writes a new grub.cfg.
I'd suggest writing the tinycore boot entry into custom.cfg (needs to be created next to grub.cfg if not present) so it won't get lost if you update grub. Boot menu entries from custom.cfg will always be included in the boot menu if the file is present.
Code: [Select]
### BEGIN /etc/grub.d/41_custom ###
if [ -f  ${config_directory}/custom.cfg ]; then
  source ${config_directory}/custom.cfg
elif [ -z "${config_directory}" -a -f  $prefix/custom.cfg ]; then
  source $prefix/custom.cfg;
fi
### END /etc/grub.d/41_custom ###
