UEFI CD boot on Getac Laptop

(1/2) > >>

Anyone have any luck booting a Getac laptop using Tinycorepure64-10.1? I was able to get it to boot but only with a USB stick, never with a CD. All I ever get is a single underscore in the top left of the screen. We used to have an older model that was uefi/bios bootable and it worked fine but now that we've upgraded to the S410G4 model it only supports uefi boot. I've poured through the forums and see people say they have had success with a CD but there's not much documentation on how it was done.

I was also curious if it potentially has anything to do with the base image (efiboot.img) in /EFI/BOOT/ being a DOS/MBR boot sector, when I would most likely want a GPT/EFI image?

Nvm figured it out.

Hi ,

I have booted using EFI. Its a bit of work.

This blog helped me a lot: https://www.parkytowers.me.uk/thin/Linux/TinycoreUEFI.shtml

You will need to create a vfat partition of about 1000 mb where you need to place the EFI related boots. Also using Gparted you need to set the boot and esp flags.

The remaining space can be used for other stuff. The best idea is to copy the cde folder from your usb image to this EFI partion.

Let me know if you are able to do it - else I will post a video using youtube on steps.

When I hear people talking about an ESP partition size (for UEFI boot) of near 1GB (=1000mb) I feel sick. Do not that people realize the fake that Micro$oft is spreading about its selfish interest?

Have you ever imagine that you can UEFI boot from an ESP partition of less than 30 MB (or what ever is the MINIMUM FA16/32 size); The hint: grub in ESP but kernel can be in ext2/other partition.

Or that you can have MANY (lest say 4) ESP partitions in any order on your HDD/SDD, be it MBR or GPT partition scheme?

Or even that your grub of less than 160 KB (yes KB not 20 MB) can boot from fat32 ESP the linux on ext2 partition? Hint: grub has only necessary modules built-in to see the ext2 partition, then kernel takes over.

Not yet? Then Sorry, you need to learn more about (just search this forum about info how can be done).
FYI: "tiny" is not a good friend with "giga" (bytes, whatever).

Not quite sure about the rant.

If you know better educate us ...
