For the UEFI booting problems.
Do not use Grub4dos boot loader.
Use a UEFI boot loader like Grub2 that fully supports UEFI booting.
Puppy now has a full UEFI compatible installer program.
Frugalpup Installer.
http://www.fishprogs.software/puppy/fru ... index.html
It does frugal installs to any drive.
It can install a UEFI, Legacy bios, or both boot loaders.
If you instal a UEFI boot loader it installs everything needed to boot with secure boot enabled in UEFI.
Along with the UEFI boot loader, it installs the Puppy security key, needed for secure boot enabled.
This is how to install to a USB stick, but this also works for internal drive, if Puppy is the only OS on the internal drive.
Use Gparted program.
Setup the USB stick with 2 partitions.
First one, small 300MB, fat32 format, flagged boot. (location for boot loader files, boot partition)
Rest of drive, whatever other partition(s), but one ext3 or 4 format. (location to put frugal installs)
(this is UEFI standard requirement, and some computers, look for a fat32 partition, for boot loader files)
Run Frugalpup Installer main program.
On the main window are selection buttons.
Select the Puppy button, to do the install.
Go through install process, selecting to install to the ext formatted partition.
Note:
When selecting the partition to install to.
A window pops up, giving option to make a directory, to put the frugal install in.
I make this directory and usually name it, the name of the Puppy version.
Carefully read that windows info.
Press enter, makes the directory, not the OK button.
complete the install.
When it gets back to the main Frugalpup window.
Select the boot button.
Select the location of the frugal install, on the USB stick.
Select the small 300MB partition on the USB stick, as location to install the boot loader. (may need to scroll the selection window)
Select the boot loader type.
UEFI
mbr ->legacy bios boot
both
You can install the UEFI for UEFI computers, mbr for legacy bios computers, or both, to boot anything.
The UEFI will also install the needed files, to support secure boot enabled in UEFI.
When you first boot the USB stick, on a UEFI computer, with secure boot enabled.
A process will start, to allow you to install the Puppy security key, to the computer.
It will add this Puppy key, to the other ones, loaded on the computer.
Note:
Not all UEFI computers are the same, for booting from a USB stick.
Some may require secure boot disabled, CSM enabled, or legacy boot enabled, to be able to boot from a USB stick.
So, for those computers.
The mbr boot loader will work, because the UEFI bios, is basically in, legacy bios operation.
To put more frugal installs on the same USB stick.
Do the complete Frugalpup Installer process again, for the new Puppy version.
When you run the boot loader install.
It will make entries, for all installs it finds, on the USB drive.
If another main stream Linux or Windows is on the internal drive.
Better to edit their menu with an entry to boot Puppy.
However, work is being done booting other OS.
Frugalpup v26 is now able to also make boot menu entry to boot Windows.
