Last post by fasterubuntu - February 19, 2024, 19:45:07 PM

Wow, that worked in a regular ubuntu installation!, boots much faster, it was /dev/sdd2.
Thank you!

However I'm now trying to boot an encrypted installation, with no luck.

The regular ubuntu installation has two partitions, a small FAT partition and a big ext4 partition, I put the plopkexec.cfg file in the ext4 partition, "/boot" folder where the files vmlinuz and initrd.img can be found.

The encrypted installation, has three partitions, the same as above and a third encrypted partition.
There is no "/boot" folder in the ext4 partition, I had to make one to put the plopkexec.cfg file in.

The files vmlinuz and initrd.img are in the "/" folder instead. I changed the plopkexec.cfg file accordingly and the ubuntu installation is detected by plopkexec, and it starts to boot but it doesn't boot correctly, it asks the password in a different way and then it gives some errors and ends up in a "busybox" shell asking for commands.

When booting normally in a usb 2.0 port, whatever I put in the ext4 "/" folder, will appear in the "/boot" folder of "computer".

[/boot/plopkexec.cfg]

Hello,

Is there any way to make it boot anything or at least an already installed ubuntu?

Yes.

On your Ubuntu installation create the file /boot/plopkexec.cfg

Code Select Expand

label Ubuntu - Hard disk
kernel /boot/vmlinuz
append root=/dev/sda3
initrd /boot/initrd.img

Maybe you have to change the 'append' line and change /dev/sda3 to your Ubuntu partition.


PlopKexec will find this configuration file and you can boot Ubuntu.

Boot Managers / Booting ubuntu on an expressca...

Last post by fasterubuntu - February 18, 2024, 22:20:21 PM

Hi there.

I like installing ubuntu on usb drives.

My laptop has usb 2.0 ports only. I bought an expresscard that gives my laptop two usb 3.0 ports. It is fantastic and works very well, except I can't boot from these usb 3.0 ports.

I've been experimenting with plop software and...

Plop boot manager 5 doesn't seem to be useful.
Plop boot manager 6 freezes.
Plopkexec works!! , it blew my mind, unfortunately I can boot only ubuntu/lubuntu usb installers.
It doesn't recognize usb drives with ubuntu already installed.

Is there any way to make it boot anything or at least an already installed ubuntu?

I'm not a linux wizard.


Thank you.

Last post by SelfRef - February 04, 2024, 16:50:12 PM

Hi, I noticed the latest version of PBM6 (pbm6-20230818.zip) contains non-working floppy image (pbm6.img). On either Qemu or real hardware it just doesn't boot without any error. On real hardware floppy drive is active for a while then nothing happens.

For the comparison, the previous version (pbm6-test-20221118.zip) doesn't have this issue and works just fine.

Boot Managers / Won't boot from USB loaded wit...

Last post by gooza1 - January 05, 2024, 13:33:06 PM

So I have a lenovo mini thinkcentre running windows 11. yesterday the OS updated and now all i get is a black screen and it will not boot. All connections are good and the monitor is working as it flashes HDMI and monitor controls but no logo and I tried everything to get it to boot and nothing works. Using another computer i created a boot disk on a USB and then I downloaded Plop onto the USB and tried to boot my PC. It doesn't work. All i have is the same black screen/ What am I doing wrong? How can i get it to boot again?

Last post by Xeubuntu - January 03, 2024, 22:53:03 PM

Yes, it is:

http://grub4dos.chenall.net/
http://reboot.pro/index.php?showtopic=22544

With chainloader non of the plop/pbm6 variants seems to work.
Linux16 I didnt try much.

Loading CD images works perfect and almost out of the box.
menu.lst and .isos have to be placed at /efi/grub
Keep in mind case sensitivity - efi is needet in small(!) letters for the menu.lst to be found.

Thank you Elmar for your quick replies and useful suggestions.

Simple as this .isos will be copied to ram and chainloaded:
title Image
find --set-root /efi/grub/image.iso
map --mem /efi/grub/image.iso (0xff)
chainloader (0xff)

Will be in holiday for two weeks soon.

Would be super interesting, if someone tries out the grub4dos efi & linux16 route.
This could be super interesting for those, where the plop efi variants don't work.

Thank you Elmar for your quick replies and useful suggestions.

Interesting. I did not know that there is a EFI version of GRUB4DOS.

Grub4Dos EFI did work. Almost out of the Box. Only issue -loading the iso to ram from nvme is slower than running it from usb2. Approx. 8MB/s loading time:

title Image
find --set-root /efi/grub/image.iso
map --mem /efi/grub/image.iso (0xff)
chainloader (0xff)
