So I just bought this laptop the other day; its a Dell Latitude e5500. It has Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2; 2gb ram, 160gb hdd Mobile Intel® GM45 Express Chipset. When I bought it, Windows 7 came with it.  After setting up Windows 7, the computer was running really slow. I thought that it might just be the ram, but when looking in the task manager I saw that the CPU was constantly running at damn near 100% the whole time. So I decided to upgrade to Ubuntu 16.04.  So I used unetbootin to install Uubuntu, then did the full install. Once I had Ubuntu on the comp.   Now I saw the windows 7 partition on the desktop, and unmounted it; because I don't want windows 7 anymore and I didn't have anything on there that I wanted.  But now Ubuntu is telling me that I only have a 10gb hard drive when I should be seeing a 160gb hdd.   How can I find and access the full HDD so that I can utilize all of that space?

I installed Ubuntu 14.04 onto my Acer Aspire E15. The PC has a 500 Gigabyte HDD.   During the installation it divided the HDD into separate partitions. However every time I turn on the PC it goes directly into Windows 8.1. It doesn't allow you the opportunity to select which OS you want to use.   Question 1: How do I set the PC so it will allow me to select the OS?  Question 2: And if #1 isn't possible. How to I remove Ubuntu from the PC and recover the partition for Windows

I'm trying to install Ubuntu 14.04 LTS on an HPG60 Laptop. I'm having a difficulty to install this coz I cant see the unallocated space I prepared in Windows.  As you can see on the attached screenshot:    I've prepared an unallocated space 96.72GB using Disk Management.  But when I boot up ubuntu and check Gparted,  I'm seeing this instead    An unallocated space of 1MB?!  Never encountered this before. I've installed ubuntu on a lenovo laptop that I use on office but I never like this before. Anybody have any idea why this is happening?

I installed 11.10 ~two weeks ago and run into some strange troubles recently.  Installation was on brand new laptop with clear 160GB SSD. I opted for encrypting home directory. Apart from that I accepted defaults during the installation. There is no other OS on my laptop.  I had circa 40GB in use when (for the third time) I got to see this very unpleasant window:    Twice situation was pretty bad and whole system slowed down considerably. After reboot I could not login to graphical interface (with an error message informing about insufficient space) and had to remove some files from command line first.  Third time I still managed to quickly delete some files and it helped.  My laptop is mainly work environment: so no torrents, games, just two movies. Only media filling space are ~20GB of pictures, and bunch of pdfs. Working mostly on PostgreSQL &amp; PostGIS, GeoServer and QGIS recently.  Although I had lots of opportunities to test and practice my backups I would be extremely grateful if somebody could point me to any potential solutions to this problem.  My laptop has been bought just before I installed Ubuntu, and it came without OS. Could that be hardware issue?  Or is the encrypted home causing me headaches?  Thanks for help!

Following  comment I was trying to recover more space and running Bleachbit application when I got another error of low space on HD. Then the system froze. How on earth can my Ubuntu fill up HD with over 100GB within minutes?

After purchasing a Lenovo Ideapad Flex 2 14, I tried to upgrade it and replaced the HDD with an SSD from my older laptop. After putting in the SSD, I encountered a numerous amount of problems.  First, the Windows installation program didn't see the SSD, even the Diskpart utility didn't see it, so I decided to install Ubuntu instead, which was installed successfully. Everything was fine, but after messing around with the BIOS, the laptop wouldn't load the OS unless I first went into BIOS and exited it.  Windows still never saw the SSD, even after I installed Ubuntu on it and then tried to install Windows again. What could be the problem? Also, the HDD that came with this laptop works just fine, and the SSD works in another laptop just fine, too. The SSD is Intel 335 series 240GB. I'm gonna try to install Windows 7 a little later and see if that will work, but other than that I've already wasted an entire day trying to figure it out.

I want to install Ubuntu on my dad's computer. The trouble is his computer will not boot from the live cd. I think the trouble has something to do with the bios. It is an Acer,model number 4520 and currently it has Windows Vista on it. How do you find bios on this computer? Here are some more details about the computer:   120 GB harddrive 64x2 dual core processor up to 384 MB NVIDIA GetForce  Thank you all in advance for your kind and generous support.

I am having windows 10 pro 64 bit OS,With 4 Gb RAM. But in memory section its showing 2.66 GB usable. Why? doing some research(Googling) I found that 32 bit machine can't utilize the full RAM. But though I am having 64 bit machine, still why its showing 2.66 GB usable?

I've upgraded my laptop (Lenovo Z50-70) which has an i7 CPU and 8Gigs of Ram to Ubuntu 16.04 from 15.10. I've been installing updates consistently. I'm using ubuntu with Gnome desktop environment (GDM).  Lately I've been experiencing a weird problem, my CPU (including all 4 cores) are 100% used by some processes like gnome-software(Gnome software) and fwupd(Firmware update daemon). This makes my work goes down. If i even kill those processes, they are starting back again.   Is there a solution for these processes to not utilize 100% of my CPU. And I don't want answers saying use the cpulimit utility to provision the amount of CPU for those processes. I find this a core problem in Ubuntu, i'm expecting real solutions for the problem.   What I've tried so far is, Removing those PPA's i've added except the official PPA's for checking updates. That didn't work out! Attached a screenshot of htop screen of these processes.

I just replaced a "broken" hard drive in a Dell Inspiron N5110 laptop and it looks like Windows 7 is gone.  Is the operating system saved/stored on the hard drive?  If so, does that mean I need to buy a new OS or is there another way?  I have a warranty on this computer: could a failed HD be covered?

My friend borrowed my laptop for a while and when he gave it back he said he replaced Windows 7 with Ubuntu. I asked him to switch it back simply because I prefer Windows. He claims not to know how. I don't want to go buy a new windows 7 disc I just want to figure out how to get rid of this Ubuntu and Windows 7. If anyone knows a way please let me know...

I wonder if someone can help me? I am fairly new to trying to actually understand and use computers myself rather than just buying whatever Windows/Mac wants me to! You will get a giggle from my flawed attempts anyway :-)  I would like to start using Ubuntu on my PC, just got a new harddrive and did have a borrowed windows 7 disk as was planning to temporarily install it so i could get ubuntu. However I didn't have high enough spec hardware for win 7 (I think it is due to only 1gb ram, i do have 64 bit technology and a 1tb harddrive). I am quite happy to install 32 bit ubuntu and hear it is easier the use than 64 anyway.  So I have one other rubbish mini laptop (windows xp) which i am trying to use to get ubuntu onto a usb (laptop has no cd drive) so i can install it on the pc. First tried just downloading ubuntu 13.04 desktop onto a usb and trying to boot the pc from it which gave the message 'no operating system'. Then I tried this to create a bootable usb which sounded promising:  . However then it starting asking for my saucy desktop iso in order to install it onto the usb stick, can't really manage to find out what a saucy desktopp iso is, maybe a mirror image of an operating system, no idea why i would need that.  So in short, I'm lost. All I can think of is getting windows xp somewhere so i can get my pc to work and install ubuntu from the internet on that, or going to a friends house in the hope that creating a bootable cd is easier than creating a usb.  Sorry for my general ineptness and hope someone can help!

I have a fresh install of Windows 7, and my RAM in normal startup goes up to 2.5GB. I looked at Task Manager, and there's at least 1.5GB missing from there and in Resource Monitor as well. There's no indication of what's using that RAM. Can someone tell me how I can find out what's consuming my memory? I believe it's a virus, but none of the free antivirus programs tracked it down.   I added the pictures below. If this is normal usage of Windows 7 as some answers imply, then I don't get this at all.   P.S. My Windows 8 Installation was running below 2.5GB, actually it was 1. something, until recently that I transferred some files from another computer which had the same problem that mine has now. I deleted Windows 8 and installed Windows 7, since I would do that anyway, and now I'm getting high memory usage in Windows 7 as well.   (Click images to enlarge)

I am total noob in Linux. I wanna know what is the equivalent of "My Computer" in Ubuntu 11.04. I want to check my computer specs such as Processor Speed, Memory, and etc.  Whenever I check properties in Home Folder it only gives me the HD capacity. I also tried looking at System Settings but I can't find it there. Please help.

I've posted a question  that I have a 32bits windows 7 on a dual boot machine with ubuntu 10.04 upgraded to 11.04. From the responses I had from the questions, I decided to reinstall the windows 7 but this time a 64bits version.  I've install the grub on the first section of the HDD on which ubuntu is install, meaning the 2nd Drive.  I still want guidance before I proceed.  What would you suggest me as best way to achieve that without disturbing the boot loading.  thank you for reading this.

I have Ubuntu 18.04 dual booted with Windows 10. Windows 10 shows full 8 GB RAM.   But in Ubuntu it shows only 6.8 GB.

I have an ACER Aspire laptop. Model number is E5-573G-56RG. I bought it only 15 days back. There is no DVD drive in it. I have tried various versions of Ubuntu- 14.04.2, 14.04.3, 15.10, 12.04.5. Tried disabling secure boot, fast startup. I current have Windows 10 Home and Windows 10 PRO (not-activated) installed with GPT partition in UEFI bios. I actually want only the Home edition and Ubuntu 14.04.3 (preferably because of LTS) or 15.10. In case more information is required, kindly ask me..  I tried installing through Wubi, when booting if I choose Ubuntu it automatically restarts and goes into Windows 10 Home! (I didn't have Windows 10 PRO at that time)  NONE OF THE SOLUTIONS I REFERRED HELPED ME.  I have spent 5 days (literally at least 20 hours reading all of them and trying out all kinds of editing in the grub command line, like removing quiet splash, adding and replacing with nomodeset, no splash, acpi_osi=off, acpi_osi=Linux, acpi_backlight=vendor,  acpi_backlight=legacy, noveau.modeset=0, i915.i915_enable_rc6=1 and such things! But I was not able to succeed installing which is why I doubt if there is some more thing to be done or know exactly what has to be done.
