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

You could run the backup software within QEMU started from a Linux that booted from a Live CD/USB.

Does the backup software run under Linux?

Still the same result, using  set gfxpayload=keep - it stucks during looding, showing the choose entry, without entries. This is normal behaviour, no matter if loading windows or lubuntu.
It is a Celsius M720. The machine itself works very reliable. There is a malfunction, detected devices, except pcie nvmes, are shown in the bootmenue any more. I did reset cmos, reflash bios - all without effect. Trying to fix this I have spendt two days already.
CD drive is also not in the boot options any more. I produced image with lowest possible write speeds, they are well recognised within bios and operating systems, but not available in the boot order any more.
I need to boot backup software and recover the operating systems. This is not possible from within operating systems. Ideas left:
- find missing parameters
- test efi version
- it should be possible to load the non efi version macrium stick directly from grub, always leave it at the same usb slot.

Is there any posibility to make linux16 availabe, or do I have to reinstall the whole multiboot system?

EFI is completely different. linux16 is not possible.
