Title: CorePlus-13.1.iso can not boot on a UEFI only system.
Post by: lovelypp on November 24, 2022, 01:52:32 AM

I make a bootable flash disk(udisk) using CorePlus-13.1.iso, but it can not boot on a UEFI bios.  When uising another computer, which support legacy boot mode, it can boot up normally.

My question is:
   Can CorePlus-13.1.iso support boot from a UEFI bios ? how ?


thanks!

The CorePure64 iso should uefi boot.

it's very strange.
 
i use a flashdisk(udisk) and rufus to make a boot media. and boot the computer from it.
is there any other suggestion ?

Are you still trying CorePlus or did you try CorePure64?

I can confirm the same with CorePure64-17.0.iso

I wrote my USB key with BalenaEtcher.
I try to boot on an Asus T100 Transformer. Secure boot is disabled. When booting, the boot menu doesn't display the USB drive.
And if I do the same with an ISO of Haiku, the drive is selectable in the boot menu.

Hi Elwood

I have an old ASUS T100-CHI tablet that is not Linux friendly.
It has a 64 bit Atom but 32 bit UEFI firmware.

I also found out this tablet would not boot a 32 bit kernel, so I used vmLinuz64 with
Core64 (not CorePure64) so I could still run 32 bit applications since this tablet only
has 2 Gig of soldered in non expandable RAM.

To create Core64:
Download  rootfs.gz  and  modules64.gz  from here:
http://tinycorelinux.net/17.x/x86/release/distribution_files/

Then:

Code: [Select]

cat rootfs.gz modules64.gz > Core64.gz
Download  vmlinuz64  from here:
http://tinycorelinux.net/17.x/x86/release/distribution_files/

Place  Core64.gz  and  vmlinuz64  in your boot directory and
point the boot loader at them.

If you have any  6.18.2-tinycore.tcz  extensions installed, you'll
need to run:

Code: [Select]

update-everythingso it fetches  6.18.2-tinycore64.tcz  versions of those extensions.

It’s also possible to install a 32bit uefi boot loader using the grub2-multi extension in the x86 repo.
