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.

Hello SelfRef,

please try this floppy image. I rewrote the loader.

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?

Boot Managers / Re: Integrate Plop into Lubunt...

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)

Is it maybe possible to integrate the Macrium stick into grub,

I don't know how Macrium boots. I hear the first time from this software.

Maybe chainloading grub4dos uefi and starting plop from there is a solution?

This will not work.

I am unable to boot from cd or usb, as described.

I know, but you can do the following.


Add PlopKexec to GRUB2.
Boot -> GRUB2 -> PlopKexec -> Boot a Linux Live CD/USB (maybe Plop Linux)
On the Live Linux use QEMU with the device nodes of the internal drive, the device with Macrium and some performance options.
Start QEMU -> Use Macrium.
Reboot to the real system.


I don't know if you want to create a backup or restore a backup. So, maybe there have to be some tweaks.

The backup software is Macrium. Macrium does not work from inside Linux. I tried a lot of other solutions.
Acronis True Image, for instance, is not able to recover valid images in some cases.

I am unable to boot from cd or usb, as described.

Is it maybe possible to integrate the Macrium stick into grub, until efi plop works,
or is there maybe a newer efi test version available?
