For a while now, I've been trying to think of a way to install some distro of Ubuntu on an old tower I have.   The tower is running dual Xeons, with a Quadros graphics card, 4GB RAM and SCSI type hard drives. It originally came with Windows XP installed, and might be 32 bit.   I attempted loading a Live image of Ubuntu 14.04, but it failed. I'm under the impression that 14.04 is too new for the machine.   Anyone have suggestions?  Edit: The machine in question is an IBM IntelliStation Z Pro, Type 6221-47U. Components:  CPU: x2 Xeon 3.06 GHz RAM: 2 GB DDR (1? 2?) GRAPHICS: unspecified  It does have a DVD drive (two actually) so booting from a disc shouldn't be an issue. If I remember correctly, that's what I tried before.  A couple specific questions I have:  Does Ubuntu have any trouble handling multi-CPU systems, or should I expect it to work as normal?  Does Ubuntu natively support SCSI drives?  This machine will hopefully be used for a CNC mill control station, so it just needs basic functionality.

For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and  such as:    with a lighter desktop than the usual Gnome and Unity  with the even lighter LXDE desktop   Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?

I am a bit financially strapped and received a Gateway GT5056 tower. The tower has an AMD dual core 64-bit processor in it. Will Ubuntu 12.04 run on this machine? I will not have any other application other than LibreOffice installed.

I'm a completely new user of Linux and since my computer is not a good machine I wanted to install 32 bit OS, I downloaded ubuntu desktop for 32 bit but when I check in system settings under details it says my OS type is 64 bit, I downloaded it from the site  choose Ubuntu 12.04 LTS and set it as 32-bit (machines with less than 2GB RAM).

How do you do a headless install of linux? No monitor, no keyboard. Machine has floopy and cd drive. Can I configure a live cd to run sshd with a preconfigured pass or something similar and manage it via that?  Instructions for fedora 8+ would be ace but anything else also welcomed.  Cheers.

I have already dual systems : Windows 7 and Ubuntu installed on my laptop. The Windows 7 had been installed when I bought this laptop, and I don't have a CD.  I just installed VitrualBox under Ubuntu, hoping that I could install another Windows in this virtual machine, so that I could run some applications of Windows even under Ubuntu.  But it seems that I need a CD or ISO of Windows to boot inside this virtual machine. Otherwise, there is an error: FATAL: No bootable medium found! System halted. My question is where I could find a CD or ISO?  At the moment, I am downloading ISO from this , but do not know if it will work. By the way, I am not sure if I should pick the 32-bit or 64-bit? As my CPU is 64-bit but my Ubuntu is i386.  Could anyone help? Thank you very much.

I have ubuntu production server 12.10 x64 installed on system with hi end hardware. I want to change mainboard, cpu, and ram to older ones. Basically from current system only hdd will remain unchanged. Is that safe to do? Can I do it without reinstalling system?

Can every CPU (in my case a Intel i7 890) install both of them ? Amd64 and i386 ? I would like to install Ubuntu 64bit. So what is the right download ?

I have a dilemma and I don't know what to do.   Currently I have Ubuntu 14.04 64 bit installed along side Windows 7 64 bit and everything works wonderfully.   I recently started a course about Assembly on Linux and the professor recommended downloading Ubuntu 12.04 32 bit.   I downloaded the iso file and loaded it on to a USB.   When I first installed Ubuntu 14.04, it gave me the following 3 options:  1) install Ubuntu alongside Windows  2) delete Window and install Ubuntu 3) Something Else   I choose the first option. However, when I attempted to install Ubuntu 12.04 32bit along side Ubuntu 14.04 64 Bit and Windows 64 bit, the first option was gone. Instead I was given the following 3 options:  1) Delete 14.04 and install 12.04 in its place  2) Delete both 14.04 and Windows 7 and install 12.04 as replacement  3) Something Else   My question is this: is it advisable to install Ubuntu 12.04 32 bit along side Ubuntu 14.04 64 bit and Windows 7 as the Ubuntu Installer no longer gives me this option? Should I just go ahead and replace 14.04 with 12.04 for the duration of time that I would need it. I don't want to delete 14.04 but I will if need be. I also like the current Dual boot option Ubuntu has put in place so if making a 4th partition through way of "Something Else" would delete that, I would much rather delete 14.04 to make room for 12.04. Again my preference would be to have Ubuntu 12.04 32 bit appear alongside Ubuntu 14.04 64 bit and Windows 7 when I boot my computer, but short of that, I would settle for Ubuntu 12.04 32 bit appearing alongside Windows 7 for the time being. I look forward to your advice.

I've been using Ubuntu for 2 years and now I want to make my own. I just decided to get the Ubuntu minimal iso for the core of my custom Distro ... but everything seems so confusing!!! could anyone give me some help about how to start and add some packages and X, a good documentation could help as well.

I would like to install Ubuntu on my Windows 7 64-bit PC to do analysis of astronomy data. The data files are often large (can be few hundred MB, possibly a GB). The data files may be located on an external hard disk. The PC has 6 GB RAM and 670 GB hard disk.   I'm trying to decide whether to do a proper dual-boot, installing Ubuntu in its own partition (I'm nervous of messing around with the hard disk, have never done it before) or to run Ubuntu using VirtualBox in Windows. How much slower is running in Virtualbox likely to be?   If I do go for a traditional dual-boot, would it make sense to divide the hard disk more or less equally between the two OSs?  I would be very grateful for some advice.  Many thanks Kevin

Ok, I've always, for some reason, thought that my cpu had 32 bit registers... so I always installed the 32bit version of all OSs that I've used. Now though I ran a lscpu, and I get:  fer@fer-lap:~$ lscpu Arquitectura:          i686 CPU op-mode(s):        32-bit, 64-bit   Does this mean I can use 64 bit OSs?  Running these I get:  fer@fer-lap:~$ grep flags /proc/cpuinfo  flags       : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm lahf_lm dtherm   And I have read that the lm flag means long mode, which stands for 64 bit cpus. Also, as a last test, running lshw gives, for the cpu section:   *-cpu:0               descripción: CPU               producto: Intel(R) Core(TM)2 Duo CPU     T5800  @ 2.00GHz               fabricante: Intel Corp.               id físico: 4               información del bus: cpu@0               versión: 6.15.13               serie: 0000-06FD-0000-0000-0000-0000               ranura: U2E1               tamaño: 2GHz               capacidad: 4096MHz               anchura: 64 bits   It's in spanish and the last line stands for width (I guess register width). So... can I install the 64 bit of the OS? Will it be a big diference in performance? Because that's what I'm looking for (doesn't need to be a BIG difference)  Thanks in advance.

I have recently got an Alienware M17x R4 and since it has two hard drive bays I was thinking of putting my hard drive from my old laptop and installing Ubuntu on it without making any changes to the drive that has Windows on it. Also if possible to add a entry to the Windows boot loader to boot Ubuntu instead of using GRUB.

I have an older HP netbook and am looking for a 32-bit version of Ubuntu 18.04 desktop. Can you advise if one is available?

Not sure if the title is specific enough, so here we go:  I crashed my Windows pc, and now I want to install Ubuntu on that computer. I'm currently using my Mac, as it is the only operable computer I have left. I have downloaded the .iso. I guess my question is; How do I go about installing Ubuntu on my crashed computer from the external harddrive? I've used Ubuntu before, but I used to install it from a CD-rom. I tried reading the instructions, but couldn't really understand them. Please help  Edit: As Tom mentioned, I only want to install Ubuntu on the (formerly) Windows machine.  Anyways, thanks for the quick responses, I think I've got it from here. Cheers

My laptop diagnostic shows several pre-fails and has other issues so I am urgently shopping for a new laptop, my second using Ubuntu. I need a laptop with good graphics capabilities and have come across a couple with the Nvidia GeForce 840M graphics card. In other words, I do not have a problem now and am hoping to avoid one.  My research on Ask Ubuntu and elsewhere shows that there have been some bugs with Ubuntu 14.04 and Nvidia drivers (not just for the 840M driver) but that fixes were made or a least suggested. But I have seen nothing definitive, e.g. the Ubuntu Certification for laptops is barely starting with 14.04.  I am about to spend a 1000 dollars and would love a little more assurance before I proceed -- my understanding is that a Live CD cannot perform a full simulation. Are there easy-to-recognize concrete factors which make compatibility (more) predictable, such as specific models of computer and their processors?  I am a considering a  with an Intel i5 4200M  and an  with an Intel i7 4700HQ. Both use an Nvidia 840M graphics card.

Are there any drawbacks to installing Ubuntu 13.10 (and soon 14.04) in Legacy BIOS instead of UEFI?  I have installed 13.10 64bit in Legacy by mistake and was just wondering if it would hurt anything to simply leave it there as is?  EDIT  Everything seems to be running just fine in Legacy and all my drivers work.

I'm currently running Ubuntu 14.04.2 Desktop.  The System Monitor tool is showing me 32 CPUs when I'm expecting 56. Should I be concerned?  Screenshot of System Monitor:    As you can see, it shows 32 CPUs.  Output of lscpu:  ~$ lscpu Architecture:          x86_64 CPU op-mode(s):        32-bit, 64-bit Byte Order:            Little Endian CPU(s):                56 On-line CPU(s) list:   0-55 Thread(s) per core:    2 Core(s) per socket:    14 Socket(s):             2 NUMA node(s):          2 Vendor ID:             GenuineIntel CPU family:            6 Model:                 63 Stepping:              2 CPU MHz:               1337.882 BogoMIPS:              5189.07 Virtualization:        VT-x L1d cache:             32K L1i cache:             32K L2 cache:              256K L3 cache:              35840K NUMA node0 CPU(s):     0-13,28-41 NUMA node1 CPU(s):     14-27,42-55   As you can see, according to lscpu, I should have 56 CPUs.  htop is also showing me 56 CPUs.    My machine is . It has 2 Intel Xeon E5-2697 V3 processors, each having 14 cores and capable of 2 threads per core (as seen in the output of lscpu, and further confirmed in BIOs).  I recall seeing 56 cores under System Monitor when I launched it in the "try ubuntu" mode from the installation disk before installing Ubuntu.   Is there something wrong with my system configuration? If there is (e.g., hardware failure), what can I do to verify? Also, I noticed that my System Monitor does not have a "System" tab.
