If I'll do dd if=isofile.iso of=/dev/sda2 will it work? I need to install a system from iso to the other partition with no use of external drives (from sda1 to sda2 for example).

  • That will make the SDA2 usable for installing to a different partition; the copy on sda2 will not be installed but installation copy of the ISO that can be used to later install elsewhere. – guiverc Dec 18 '22 at 00:08
  • @guiverc will this iso (written on sda2) be listed during boot? – Ya Y Dec 18 '22 at 00:18
  • No... I've done what you describe, and I modified my existing Grub menu to allow me to boot on my system (that had no working USB ports) so I was offered the choice to boot the ISO-on-partition. FYI: You can do the same & just boot the ISO from an existing file on partition too which would be what I'd do today, as using a whole partition instead of just a file makes little sense to me these days with larger disks (it made sense when disks where measured in MB not GB/TB) – guiverc Dec 18 '22 at 00:30
  • If your computer boots UEFI, you can just extract the ISO to a new, (8GB), FAT32 or NTFS partition and it should boot as Live OS. – C.S.Cameron Dec 18 '22 at 04:14

It will do something, but it won't do what you want.

dd is not an installer. It's simply a copy machine.

Copying an installer simply makes another installer.
