guys I have an issue with Linux
I wanna install Linux on flash disk like internal disk
actually I wanna install it with presentation space
I did it but it limited with 4 gig space.
I wanna use all space of flash disk and do my works on it like an internal partition
like a really OS
In the normal installation process, you will be asked to select the partition on which you would like to install Linux.
The option for bootable USB will be visible with a warning sign. In some flavours, it may be hidden however, you can still install it. Simply click on the USB drive partition and Linux can be installed on it.
Make sure you have at least 16GB USB Flash drive to run your Linux smoothly.

So I booted Parrot OS from an external drive (SanDisk 3.2Gen1) and I gave it 32GB of persistence (I don't know if it really does anything to help). Now I am trying to partition the drive. Everything goes well untill i try to install it to the drive. It just pops this error and I don't know what to do next.

I have tried to do it with the GParted program but that doesn't work either.
Looks like you are trying to partition the drive the live system runs on?
If so, try booting from another drive than the one you'd like to partition.
so I have a lenovo laptop i7 with two hard drives. My ssd which boots windows on UEFI, and my second a hybrid hard drive. I created two partitions on my second hard drive. One for storage for my windows drive, and the other(500gb), where I would like to install FreeBSD. I made the two partitions in windows, and burned the FreeBSD memstick file onto a usb and booted. When I get to the installation menu, it does not show all my disks under manual installation. It only shows my USB as a partition, which is 8gb. If I try to do the guided installation and select from partitions. I get an error that says out of index 5.
Any Ideas why this is occurring?
I generally hear that LINUX OS can be downloaded on flash, pen drive (floppy disk?) etc. How we can do that?
I have RHEL 5.4 source code - so how can download it into pen drive and how much space is required?
What other functionality I can add apart from the OS - so that when I boot from that storage device I can make use of them?
Can we download Linux OS into micro-controllers also?

If you can't get it to work on your own, you can buy a ready made Linux on a USB drive from
a site like http://www.osdisc.com or http://www.cheapbytes.com
Not all PCs, especially older PCs, can boot from the USB Drive. Even some newer PCs are beginning to ship with security features that can interfere with booting code. When it does work, you have to find out the proper way to boot the USB drive. You might have only a few seconds during reboot to enter the right key, or it will boot Windows (if Windows is installed). The key to get to the BIOS Boot Menu might be delete or escape or F10 or some other key (varies with PC motherboard manufacturer). A message on the screen that flashes by rather quickly might mention keys you can press. Boot to a specific device or changing boot order can also often be found in the BIOS setup.
There is a linux utility called unetbootin that will create a USB drive that will boot linux. It does not create a USB boot drive from a source code distribution, but rather from an ISO file representing a live CD or the live CD itself.
Since large USB drives (e.g. 32GB) are relatively inexpensive, if you want to compare systems or have multiple systems there is a way to have multiple linux and other operating systems on one USB drive and be able to choose which to boot into. See, for instance, http://www.pendrivelinux.com/ which has a wide variety of procedures for making a bootable USB using either windows or Linux to set up the USB and booting a variety of systems.
I have RHEL 5.4 source code - so how can download it into pen drive
and how much space is required?
RHEL 5.4 is a bit old. You need the Live CD, if there was one.
The ISO file can take up 600+MB. You want space left over to use the system. 2GB for the pen drive is OK. Sometimes you can get by with less.
What other functionality I can add apart from the OS - so that when I
boot from that storage device I can make use of them?
Upon boot the operating system will often recognize sound cards, other usb devices, the hard drives, etc. You need to know how to use these things within Linux, and how to enable them if they are not configured. Some Linux distributions have a place to put packages that are to be autoinstalled when a USB pen drive based system initializes. In this way you can "install" software from the distribution archives that are not included on the standard live system, even if you don't have internet access.
Can we download Linux OS into micro-controllers also?
People run it on raspberry pi and such, but the versions of Linux on non-PC hardware that has low memory are often quite tiny compared to a desktop version. They can be tiny enough to be challenging to work with or expand.
I need to test a program on SmartOS. I don't have any spare systems lying around so I wanted to install it into a KVM image on my GNU/Linux distribution. I've installed Solaris 11 that way and that worked pretty well.
I downloaded the ISO and booted it inside KVM and the installation appeared to work fine. However when I boot the virtual machine it always starts to come up and says:
Booting from harddisk ...
and then it just sits there, with the virtual CPU pegged, and never proceeds any further. No key presses appear to do anything (except Ctrl-Alt-Del which starts the boot again, giving the same result).
I created my KVM from virt-manager with 2G RAM, 2 CPUs, 50G of disk space using a "raw" disk format, and selected "Solaris" / "OpenSolaris" as the OS type.
I don't have a copy of VMWare and it seems really expensive to get one for Linux, so I don't think using the SmartOS VMWare image is an option for me.
Anyone have any hints? Google shows me lots of information about creating Linux instances inside SmartOS KVMs, but nothing on doing it the other way.
I figured it out with some help from the mailing list. SmartOS is a PXE booting operating system: it doesn't actually install to the harddisk. When my installation was complete and the VM rebooted KVM automatically unmounted the ISO file from my virtual CDROM, so on boot it was looking for a PXE image to boot from and couldn't find it.
All I had to do was re-attach the ISO file to the virtual CDROM and it worked fine after that. Ugh.
This might seem like a stupid question but...
After using a USB to install Ubuntu, is it possible to use it as a regular USB again or is it like a CD install and the USB is now only good for installing Ubuntu?
Thanks.
Yes you can.
Infact you can keep the Ubuntu setup as it is and use the remaining free space to store other things, just incase you need Ubuntu installation in future.
You can use it normally, just be sure you have cleaned up the MBR for the case you leave the device plugged in at restart (when USB boot is still enabled).
Easiest is to format the whole partition (or use a partition manager to clean up the whole device). GParted should be able to do this for you.
Some (sketchy!) technical background:
The USB device is a flash device, where bits are stored non-volatile, but eraseable and changeable. Bits at a normal CD-ROM will really be "burned" in as the reflection capacity will be permanently changed when creating a CD. When booting up your computer, there is small memory ROM that contains a bootloader, that is looking up for devices containing a MBR at the first 512 bytes, that will be executed and load the OS (or in your case the first steps of the Ubuntu installation process).
So if you want to use the USB device as normal data storage again, you should also clear up these first 512 Bytes, as the bootloader from the USB could be loaded otherwise when leaving the device plugged in at reboot. Then the bootloader could throw an exception, as it would normally expect the Ubuntu installation files to be present onto this device.
