UEFI Boot Support? about tinycore-redpill

[Plarkass]

Following along with this guide, I was able to modify the USB stick: https://github.com/ndeineko/grub2-bios-uefi-usb

Got it from forum:
finally i managed to create a uefi bootable flash drive. the steps are very easy but it took me about the whole day to figure out.
after writing redpill tc loader image to your flash drive, you need a linux machine to add the uefi boot.
in my case, i have a notebook with linux mint installed (latest edge edition).
assuming that my flash drive was /dev/sdb, this is what i've done:

Mount the filesystem:
sudo mount -o umask=000 /dev/sdb1 /mnt
Write the MBR and install the grub files required for legacy BIOS boot on the drive: (i don't know if this step is really needed but anyway it works)
sudo grub-install --no-floppy --boot-directory=/mnt/boot --target=i386-pc /dev/sdb
Install /EFI/BOOT/BOOTX64.EFI and other grub files required to load grub from a 64-bit UEFI firmware:
sudo grub-install --removable --boot-directory=/mnt/boot --efi-directory=/mnt --target=x86_64-efi /dev/sdb
Unmount the filesystem:
sudo umount /dev/sdb1

+1, @pocopico do you plan to add uefi? Unfortunately, I can't use csm mode((

Still cant boot tinycore.img in ovmf(uefi) proxmox 7 vm, any solution?

I'm not using proxmox but I tried to see if I can make it work. Here is what worked for me.

1. Upload tinycore-redpill-uefi.v0.4.5.img.gz to proxmox in folder /var/lib/vz/images/
2. unpack tinycore-redpill-uefi.v0.4.5.img.gz to tinycore-redpill-uefi.v0.4.5.img
3. rename tinycore-redpill-uefi.v0.4.5.img to tinycore.img
4. Set your VM bios to OVMF (UEFI)
5. Add following to vm config (ie /etc/pve/qemu-server/100.conf)
   args: -device 'qemu-xhci,addr=0x18' -drive 'id=my_usb_disk,file=/var/lib/vz/images/tinycore.img,if=none,format=raw' -device 'usb-storage,id=my_usb_disk,drive=my_usb_disk,bootindex=5'

For reference my config looks like this:

args: -device 'qemu-xhci,addr=0x18' -drive 'id=my_usb_disk,file=/var/lib/vz/images/tinycore.img,if=none,format=raw' -device 'usb-storage,id=my_usb_disk,drive=my_usb_disk,bootindex=5'
