usb iso does not work with dd command
hello, I downloaded the 4mlinux iso and copied it to a pendrive with the dd command ... but it doesn't work, I also tried imagewriter from mabox linux and it can't copy it to a pendrive, it is the first linux distro that gives me this problem .
|
Please supply us with the command used and wrap that command in [code].
BTW, Welcome! |

How does it fail? Did you turn off secure boot?
If you have installed kvm/qemu or virtualbox, you could test both the image and the pendrive by test booting it by mapping the DVD. |
[QUOTE=elgrandeperro;6370930]How does it fail? Did you turn off secure boot?
no, how do i disable it? only 4mlinux does not start, sparkylinux, mabox, crunchbang all go, why? if I open the file manager the pendrive with 4mlinux is seen as cdrom |
Did you try a VM boot?
Just because it looks like a CD, doesn't make it bootable. |

i have installed at least 40 distros on this notebook, 4mlinux does not start, i tried both with dd command and with etcher |

#1 has it been formatted so that it SHOULD work? This is not a sure thing. #2 Did you checksum the file (as was suggested) and compare the CRC values with the expected value to ensure you have a good ISO file download? #3 did you verify that it is the image that matches your CPU architecture? #4 have you tried copying it to a VENTOY device and test from that? If it fails, there should be some error codes, messages, or fault behavior. These may not be easy to record during a direct hardware install, try installing into a virtual machine and record the messages and result. |

I downloaded that exact file using
Code:
$ wget http://downloads.sourceforge.net/linux4m/4MLinux-40.0-64bit.iso Code:
# dd if=4MLinux-40.0-64bit.iso of=/dev/sdf bs=4M The boot failed because the image had an invalid signature and secure boot stopped it, but the image on that usb was UEFI bootable. I did not try a legacy boot. When I disabled secure boot it booted cleanly. These are the checksums I got on that file. Code:
# sha256sum 4MLinux-40.0-64bit.iso |
Code:
file 4MLinux-40.0-64bit.iso |
How much memory do you have? You need 2G for 4M server edition to run the Live image.

I don't think #16 is relevant, because the OP uses other distros.
@#13 (MichaelK): I trust your huge experience/expertise, but I don't quite understand. Could you provide additional tutoring here? I did find this article: https://superuser.com/questions/6832...so-is-a-hybrid This may have actually happened to me because I vaguely remember (rare) things mysteriously not booting in the past. More: https://www.oreilly.com/library/view...1079fffd.xhtml I did not know this!!! I guess I truly am a Linux N00b!!! Edit added several days later: thanks for #19!!! I did some more web searching and found this, which seems to be a great tutorial: https://www.rodsbooks.com/gdisk/hybrid.html My favorite Hands-on Booting (one of the few books I own because I depend on my local public sclibrary.org) unfortunately makes no mention of even USB flash drive booting, only CD / DVD ( though it has a brief appendix on live isos which I think is a totally different issue) |

now it works with the hybrid iso but I saw that while using jwm it uses 1.8 gb of ram in live, sparkylinux 300/400 mb, crunchbang ++ also and mabox as well. |
!!!,
A CD/DVD boots using a completely different process from a regular hard drive which is why copying the ISO file using the dd command fails. An ISO file by convention is an ISO 9660 filesystem, the standard defines how data is written to the disk and how to make it bootable. One of the first methods to convert an ISO file to boot from USB was syslinux. The file was extracted to an existing USB drive formatted with a FAT32 filesystem and then syslinux was the boot loader. isohybrid adds a MBR to the ISO file when created which allows it to "natively" boot from a USB drive. Most distributions these days provide a hybrid ISO file which is why most people might expect using the dd command to just work. When booted the filesystem still appears like a read only CD/DVD despite it being on a flash drive. I have not played with 4M much so I can not comment on memory. For specific questions use the 4Mlinux forum here: https://www.linuxquestions.org/questions/4mlinux-115/. |
I booted from Virtualbox, but the server image requires 2GB memory or it panics. The non server requires 1GB memory.
Sorry, I haven't seen a non hybrid live iso in a while. |

Perhaps you disabled it by mistake?
