Porteus

EFI or BIOS system?

Partition structure of the USB drive?

Show the grub menu item.

@Ed Do you know if it will be mbr or gpt partitioned ? It doesn't matter, mbr drives boot just fine on EFI systems. My USB drive is mbr and boots on my EFI system. I have partionned, formatted, and copied the folders on the Porteus flash drive. And you have a bootable system? Keep in mind that I'm ...

If the expert says fdisk I strongly recommend you do as instructed.

3. Try formatting the flash... That's what my last attempt was: everything on sdd1, nothing on sdd2. AFAIK it's the same setup as having a single 2GB flash drive, fat32 formatted, shown as EFI system partition in gparted. Actually you did more than that. I retried the same partitioning scheme, but ...

Before you give up, and while waiting for better advice, can you try a couple of things? 1. Can you find a Windows machine and run the Porteus-Installer-for-Windows.exe on it. 2. Try running the Porteus-Installer-for-Linux.com on a non-Xubuntu system. 3. Try formating the flash drive as a single par...

Have you checked your 003-Mate file against the 003-Mate file in the Porteus-Mate-v4.0-x86_64.iso?

Thank you ncmprhnsbl.

I don't see the editing options.

You can boot it only from your computers where you have disabled secure boot. But outside (friend's place or at the workplace) it wont boot if secure boot is on. You cannot disable secure boot here. Good point jssouza . :happy62: So Porteus would need to develop a signed grub2 system, and I suspect...

Do you have a secure boot enabled computer Ed_P? Oh, and does it run Porteus? :) I have an EFI computer and when Secure Boot is enabled and I attempt to boot the USB drive the machine runs a RAM test then tells me it can't find a system to boot. I can only boot the Porteus 4.0 USB drive with Secure...

One step lesser, hence easier.

Download Ubuntu
Install Ubuntu to flash drive
Delete all Ubuntu files from flash drive except for ....

Definitely quicker to turn Secure Boot off.

That's 2.4 MB

True. I misread.

You need to sign the grub bootloader. Ubuntu does it with Canonical's signature, fedora with red hat's

So basically you don't boot to Ubuntu you boot to grub. Interesting.

You use 1 partition and I use 2 partition because I am using a 32gb USB and partition is the FAT 32 Boot and partition 2 is the rest and it is EXT 4 the working partition. I been using this for years but now the Acer can use the EFI and that what I want to do. I don't use save.dat file. That's fine...

That approach takes up a lot of space on the USB drive! -rwxrwxrwx 1 root root 2392064 Aug 23 11:24 efi.img* Plus all the /boot/grub/x86_64-efi files. It would be nice to figure out how the Ubuntu system supports the Secure Boot option so Porteus can do it also. But I think the Ubuntu approach is a ...

My USB drive certainly doesn't look like yours Jack . guest@porteus:~$ ll /mnt/sdb1 total 192 drwxrwxrwx 3 root root 16384 Apr 29 07:12 EFI/ drwxrwxrwx 9 root root 16384 Aug 13 23:54 Guest/ drwxrwxrwx 2 root root 16384 Aug 14 15:25 Modsavedat/ drwxrwxrwx 2 root root 16384 Aug 14 00:00 Modules/ drwxr...
