Frugal install UEFI

(1/4) > >>

Demontager:
I am trying to make frugal persistent install TC on mini-PC which only supports UEFI boot. The iso i have used is TinyCorePure64-13.1.iso, but direct boot not working, so i used Ventoy then i got tc booted. Then followed this guide to install TC to internal storage https://iotbytes.wordpress.com/install-microcore-tiny-linux-on-local-disk/

--- Code: ---tc-load -wi tc-install
--- End code ---
Before making install i did partitioning like that. Chosen ext4 partition for TC (not whole disk)

--- Code: ---/dev/mmcblk0p1  fat32 for EFI
/dev/mmcblk0p2  ext4

--- End code ---
At that point i need to install grub to /dev/mmcblk0p1 Partly I followed that guide http://forum.tinycorelinux.net/index.php/topic,19364.msg119228.html#msg119228


--- Code: ---$ tce-load -i grub2-multi
$ sudo mount /dev/mmcblk0p1
$ sudo mount /dev/mmcblk0p2
$ sudo grub-install --target=x86_64-efi --boot-directory=/mnt/dev/mmcblk0p1/EFI/BOOT --efi-directory=/mnt/dev/mmcblk0p1
Installing for x86_64-efi platform
grub-install: warning: cannot open directory '/usr/local/share/locale': No such file or directory.
grub-install: error: efibootmgr: not found
--- End code ---

Demontager:
Figured out that i missed efibootmgr


--- Code: ---tce-load -wi efibootmgr
--- End code ---
Then again did

--- Code: ---sudo grub-install --target=x86_64-efi --boot-directory=/mnt/dev/mmcblk0p1/EFI/BOOT --efi-directory=/mnt/dev/mmcblk0p1

--- End code ---
Installation reported as successful except warning

--- Code: ---grub-install: warning: cannot open directory '/usr/local/share/locale': No such file or directory.

--- End code ---
Now i got grub directory created


--- Code: ---tc@box:/mnt/mmcblk0p1/EFI/grub$ ls -al
total 138
drwxrwxrwx    2 root     root           512 Jul  1 09:55 ./
drwxrwxrwx    4 root     root           512 Jul  1 08:18 ../
-rwxrwxrwx    1 root     root        139264 Jul  1 09:33 grubx64.efi

--- End code ---

I know that i need to create grub.cfg within this folder. What will be the minimum config ?

Juanito:
If you search the forums on dual boot uefi bios you should find an example grub.conf.

Yes, i found some and compiled own grub.cfg


And it worked, partly. I got grub menu loaded with my entry, TC booted, but after trying to install some utils found that i can't install any, for example htop


--- Code: ---tc@box:$ tce-load -wi htop
tc@box:$

--- End code ---
means nothing happened. Also tried filetool

--- Code: ---tc@box:$ filetool.sh -bv
Invalid device

--- End code ---

tcedir shows

--- Code: ---readlink /etc/sysconfig/tcedir
/tce

--- End code ---

Juanito:
Can you post your grub.cfg?
