Puppy, Windows and Ubuntu triple boot

[shinobar]

Best solution is Grub2config: viewtopic.php?f=155&t=3360

Dual boot Puppy and windows, LICK runs on Windows is the easy way: https://oldforum.puppylinux.com/viewtop ... 34&t=61404

When you install Ubuntu Linux or the derivatives, Ubuntu and Windows appears on the boot menu but the Puppy not.

If you can boot Live Puppy from CD or USB device, run Grub2config to make triple boot available.
@Clarity shows a method in the next post.

Otherwise, you can manually write /boot/grub/custom.cfg,
On Ubuntu, make a file custom.cfg at the users home directory.
If you installed Puppy using LICK, you can find lickgrub.cfg at the partition corresponding Windows C:.
Copy and paste the entry item like this:

Code: Select all

menuentry "bionicpup64 8.0 (sda5/bionicpup64)"{
  search --no-floppy --fs-uuid --set=root 4cd1cb74-c8ec-4479-9e78-255824c68453
  linux /bionicpup64/vmlinuz psubdir=bionicpup64
  initrd /bionicpup64/initrd.gz
}

If you are not using LICK, see the topic: viewtopic.php?f=155&t=3931

Then launch a virtual terminal and type:

Code: Select all

sudo cp custom.cfg /boot/grub

ALSO you run this USB, it will find and list ALL of the distros on your PCs.

Then, you merely select the distro or ISO file you choose at PC boot time to get to any of the Windows-LInux-PUP-DOG desktops listed for your selection.

Further, if you have GRUB2Config installed on any of your PUP-DOG distros booted from your USB, if will do what is mentioned in the 1st post on this thread to setup your PC's HDD/SSD. Your USB that you have with your ISO files, is useful to boot your PC. Then, using GRUB2Config in the running PUP-DOG, you can fix the PC's HDD/SSD boot manager without messing up your USB.

Once fixed on the system drive, you'll remove your USB and have your PC boot the OSes on your system drive.

As you probably realize from this post, the USB can be used to get to a desktop as well as be a failsafe in case you have corrupted your PC's system boot manager.

Hope this is helpful use information for multi-boot from your PC system drive.
