UEFI boot causing big problems

diode84 · 03-31-2022, 02:14 PM

Hello
I have a Wyse 3040 thin client that I am trying to install Fossapup64 on. It will install the files to its internal ssd but will not boot. There does seem to be a problem that it must run in UEFI mode. see Parky Towers web site.I have tried grub4dos and grub2 also but still no boot, I have even tried easydd to install to ssd, it did, but no boot from internal ssd.
Has anyone any ideas.
Thanks

One upon a time I had an issue with UEFI, then installed this.. and solved the booting.

My thought for now.

On UEFI machines the Grub needs to be grub2-x86_64-efi, or same by slightly different name. If this is not the Grub version installed, it can't initiate boot on UEFI. UEFI booting requires a VFAT partition to serve as the ESP (Efi System Partition). The installation media used to install a Linux OS must be booted in UEFI mode in order for the requirements to be fulfilled, and the installation succeed to boot.

Is secure boot disabled?
Is this a dual boot with windows or another linux distro?
Are the puppy files installed on a linux or windows partition?
If on a linux partition is there a /EFI/boot directory with grub files on the linux partition?

Try copying your GRUB into the /BOOT directory on the EFI System Partition under the name of BOOT64.efi. I believe all UEFIs have to be able to boot that file. It's part of the UEFI standard.

Secure boot is disabled, no not a dual boot system and files are on ext4 file system except for EFI/Boot which is vfat.

No that did not help.

Open a console and post the output of the following

Code:

cat /sys/firmware/efi
efibootmgr
ls -R /mnt/sda1
parted -l
lsblk -f
cat /mnt/sda1/EFI/boot/grub.cfg

Assuming sda1 is the efi partition and mounted at /mnt/sda1, change accordingly.

I am working on that but so far not connected to internet on it. Also it doesn't seem to be sda1 etc as its eMMC
