I found the best results using Universal Boot Installer and your preferred .iso file
I have also found that some brands just will not be bootable. Andy |

this tool could "burn" iso into pendrive,

thing is the bootloader needs to know some things
like where to boot the actual kernel from that info in grubs case is on a text file on a partition also it should use the devices hardware name so it does'nt get confused if you put 2 usb's in the computer (lilo on the other hand just c/p-s part of the kernel) otherwise it should be just like a normal installation http://askubuntu.com/questions/180023/can-i-install-grub-on-an-usb-and-make-it-a-rescue-disk |

Depends on the distro. Though when you say "without the limitations of a live version", I assume non-persistent changes (a la UNetBootIn) isn't what you want.
Perhaps PLoP Boot Manager (or similar) would help? At least, back in the day it helped boot Puppy Linux from USB on my old P4. RUFUS claims to (also) work with Ubuntu/Kubuntu. Or maybe Fedora's liveUSB creator? At least it worked in old F14 for me. Even PC-BSD has ways to make a bootable USB, though I've not tried it. |

Octavio,
I use Puppy Linux 5.6.0. It is small and does not have the limitations that most Linux versions have. I found that Puppy installs well to pen drives compared to most other versions. Andy |

I forget what I did but I had manjaro booting from a usb, storing data on the usb etc. Maybe I googled and found some instruction. I don't remember. The USB had the separate partitions just like you would when configuring linux on a hard disk.

Standard installer of Linux Mint installs also on usb pen drive without problems. According to my experiences however a memory stick of 16GB is a minimum. First partition must start at sector 2048 (1MB). That's all. It works with or without grub.
I forgot to mention that after installation it's worth to configure your system to minimize writing to the USB drive, just as if your system used an SSD. If you have enough memory in your computer then use no swap. |

A detailed description installing extlinux on a drive and hacking your favorite linux on it using extlinux, if the iso has isolinux then it will possibly be this simple, and you an just copy the isolinux config file to extlinux:
best method i have found to boot from usb (or SSD). Code: #fdisk create first partition with max avail size and make it bootable echo "n p 1 a 1 w "|fdisk /dev/driveyouwant #install syslinux/extlinux mbr dd if=/usr/lib/syslinux/mbr.bin of=/dev/driveyouwant bs=440 count=1 conv=notrunc #reate your preferred type filesystem on your new first partition with 0 reserved space for root #can be ext3 or ext4 if the krnel suppots it. mkfs.ext2 -m 0 /dev/driveyouwant1 #mount your newly created first partition mkdir /mnt/x && mount /dev/driveyouwant1 /mnt/x #install extlinux on the device mkdir -p /mnt/x/extlinux && extlinux --install /mnt/x/extlinux #copy iso contents: unalias cp cp -a /mnt/1/ /mnt/x/ #cosmetic things... mv /mnt/x/isolinux /mnt/x/extlinux #summon extlinux configuration file, some hacking can be done if you want or need ln /mnt/x/extlinux/isolinux.cfg /mnt/x/extlinux/extlinux.conf #done, cleanup umount /mnt/x/ /mnt/1/ #how you can test it on qemu virtual pc: kvm -m 512M /dev/driveyouwant |

Ubuntu 14.04 (perhaps older versions as well) has the 'Startup Disk Creator' that will put the ISO on a thumb drive, there is also an option to allow for persistent storage.
The flash in most pen/thumb drives isn't always the best quality with regards to rewriting durability. Using a journaling file system like EXT will likely wearout your pen drive sooner than the default bootable FAT. |

Pendrive is ok for any fs, because it has wear leveling built in, also even the cheapest microsd card has wear leveling. Note that flash memory has unlimited number of reads, you only wear your flash memory by rewriting them. Ofc. do not put a swap on your pendrive if you want it to llive long. |
