My computer is Dell L521X with WIN 8.1. I want to install ubuntu alongside with win 8.1. Before installation, I've disabled Intel® Rapid Start Technology and change the boot option to legacy. But, at the step of installation types, there is no option. On the Gparted, I could see the normal partition. What's wrong with it?

I'm absolutely new to Linux. I would like to know how to install Ubuntu alongside the pre-installed Windows 8+ OS.  Should I do it with Wubi, or through the Live USB/DVD?  What steps do I need to take to correctly install Ubuntu?

I'm having a problem installing Ubuntu 12.04 on my ASUS UX31A alongside Windows 7; I tried to launch os-prober in my terminal and the only option I get is:   /dev/sda5:Windows Recovery Environment (loader):Windows1:chain   while Windows 7 (mounted on dev/sda3) is not shown.  This is what I see in my Disk Manager in Windows 7:    C: basically is the partition with Windows system's file, while the D: one is for data), while this is what I see when I launch GParted:     May it be because Windows is installed on SSD? How do I know that? Is it safe if I proceed with the installation for computers with UEFI, SSD and HDD? I'm not sure that's my case.

I have Windows 7 installed in my PC. In a failed attempt to create a partition my disk has been converted to dynamic including system and boot volumes. How can I install Ubuntu in a partition without affecting the Windows system?

I plan to install Ubuntu 13.04 alongside Windows 8, and I'm looking for a CLEAR answer on how to conduct partitioning appropriately.    I'm very new to all of this so a thorough explanation with minimal jargon would be great.  I have an Acer Aspire M5 x64 with 6G RAM.  I think I already figured out how to deal with the fast startup, UEFI and SecureBoot issues (I disabled fast startup and disabled Secure Boot).  I am able to boot into Ubuntu from a LiveUSB, and I think I am ready to install Ubuntu. Note - despite some advice found here, I do have to disable SecureBoot to boot 13.04 from my LiveUSB.  From what I have read here, it seems that I should (at least at first) create the partitions from WITHIN Windows 8, not from the LiveUSB, to avoid reported problems.  I have run compmgmt.msc and I see the existing partitions.  I see the following:  Disk 0:  400 MB Recovery; 300 MB EFI System; Acer (C:) 444.95 GB (Boot, Page File, Crash Dump, Primary Partition); 20 GB Recovery  Disk 1:  3.74 GB Primary Partition; 14.90 GB Primary Partition  I gather I need to create a mounting point '/' Partition (??), a swap partition, and a home partition.   Please explain what these are, how big they should be, how I create them from Windows Disk Management, and anything else I need to know.    Eventually, I plan to fully replace Windows 8 with Ubuntu, but for now I want to run alongside Windows 8 and not screw things up.  I don't have any critical files saved on this computer yet.  Thanks.

I am not exactly new to Linux, but I am facing problems trying to install Ubuntu 14.04 LTS on my Dell Inspiron 14z pre-installed Windows 8 with Secure Boot nand UEFI mode. **I have followed all the prescribed steps of your post regarding Ubuntu installation one of this forum's post  **.  I am able to boot to LiveUSB mode via UEFI mode. But when going through the installation process, partitions don't appear at all on the 4th slide of the install process. So I just press "Install" just to see what happens. There is a pop-up window which says "No root file system defined. Please correct this from the partitioning menu."  I have created three partitions on Windows 8 of which one is entirely free(100 GB) and formatted and ready to be installed on. Please help me resolve this issue. Thanks and cheers

I am trying to install a fresh version of Ubuntu in my computer without touching the windows 10 dual boot! In the Installation Type, the first option seems exactly what i wanted to do.  My question is, is this feature is safe to use? because i don't want to lose any windows files and other NTFS partitions on the hard-disk. Please eliminate my confusion. Note as that i dont need any files or media which are in the ubuntu partition, Thanks.

I installed Ubuntu yesterday alongside Windows 7 and whenever I start my computer I don't have the option to boot Windows. When the computer starts it goes straight to Ubuntu without giving me an OS selection menu. When it goes to Ubuntu it gives me Ubuntu repair options and Ubuntu normal start option. I still have all of the Windows 7 files on my hard drive, but Windows 7 has no way to boot.

I have a computer which is currently running Ubuntu 14.04. I would like to dual boot with Windows 8. I can not find any instructions for installing Windows after Ubuntu is already installed. I am only finding instructions for doing the opposite, Installing Ubuntu after Windows 8.

I have a PC with an OEM install of Win 8 updated to 8.1.  It has 3 physical hard drives in it.  The drive where Windows is installed has a LOT of partitions on it already.    Can I install Ubuntu on a different physical hard drive than Windows, and be able to dual-boot?  I am able to boot to a live USB of Ubuntu 14.04, so I think I'm about ready to proceed.  But if I can make my installation easier by using a different physical drive, I'd like to do that.

I try to install Ubuntu 16.04 next to Windows 10. Windows is installed on legacy bios and then upgraded to Windows 10. When I try to install Ubuntu from USB stick, it shows a message titled "Force UEFI installation?". It says that the machine's firmware started the installer in UEFI mode but there is an OS installed using BIOS compatibility mode. If I force installation I won't be able to boot Windows.  How can I start the installer in legacy mode?  BIOS of the machine supports legacy and UEFI modes. Legacy support is enabled. But USB disk is always recognized as EFI. USB disk's name is shown as "EFI USB Disk" in BIOS. I cannot change that. I burned the USB with both startup disk creator on ubuntu 14.04 and pendrive software on Windows. Same result.  Thanks.

I am trying to install Ubuntu 11.10 on a Dell OPTIPLEX 3010 IvyBridge and when I start the setup, the screen goes awry with a lot of colored patterns.  Is there a way to start the installer in text mode or a graphical safe-mode?  On Ubuntu 11.04, it works well.

I have changed my system to boot from UEFI instead of BIOS and have installed Windows 7 on my internal SSD which has GPT partition type.   I am trying to install Ubuntu 13.04 on my external HDD. My machine is a Lenovo . My HDD is a 1TB USB3 .  Here is some of what I have been trying:   My laptop is set to boot in UEFI mode. I have 64 bit version of Ubuntu, on my bootable flash disk    I took out my SSD before installing Ubuntu    Before installation my external HDD was also partitioned as GPT and it only had one 950GB partition   I tried two different methods:     First: When I let the Ubuntu to install itself automatically, without changing anything, the installation completed but Ubuntu did not boot. SSD was out and I am sure the systems boots in UEFI mode. Second: I tried to do the partitioning myself in the following order, but I still have the same problem, I am sure my HDD is partitioned as GPT:     /EFI Boot /(root)  /swap   /home     I chose to install the bootloader in /EFI boot.    Please let me know what I am doing wrong. Thanks  Update:  I was sure that Windows, on SSD, boots in UEFI mode. However, I disconnected my HDD and the windows did boot from SSD.I used the live USB to boot Ubuntu and let it do the partitioning and install Ubuntu on the external HDD. I still had the same problem and Ubuntu did not boot. Then I used the live USB and installed Boot-Repair. After running Boot-repair and a restart everything was good, and Ubuntu did boot from HDD. However, there is a line before booting into Ubuntu: ata_id[279]: HDIO_GET_IDENTITY failed for '/dev/sdb': Invalid argument But the system boots.  Boot Info Script: Here is a  I got after using Boot Repair.   I tried to change the partitioning and partition sizes. After reading , I changed the partitioning using Gparted. I also installed the bootloader in /dev/sda1 which is flagged as the /boot partition. As expected after installation and a reboot, Ubuntu did not boot. So by following  and  posts, I tried to register the bootloader to the EFI. But I was not successful. I even noticed that my machine might have  problem, and I changed the /EFI/Ubuntu/bootx64.efi name and location but no effect, Ubuntu did not want to boot.  Again, I used boot repair to solve the boot problem and it worked like the previous time and I am in Ubuntu. But I really like to know what is causing this problem. The interesting thing is that Boot Repair has created all possible folders and files. Is there a way that I know which folders are being used for boot? These are the different folders and files:   -/boot/efi/EFI/Boot/bootx64.efi   -/boot/efi/EFI/Microsoft/Boot/bootmgfw.efi and bootx64.efi   -/boot/efi/EFI/ubuntu/bootx64.efi and grubx64.efi

Long story short, I installed ubuntu while I was watching netflix and feeling very lazy, and may have lost all my windows 7 files.  Quick summary:    -Windows 7 was installed on Legacy bios and I installed ubuntu on UEFI bios -ubuntu installer didn't detect any other OS on my computer and wanted to write over the disk, so I had to manually edit the partition    -Despite repeated warnings about partitioning windows in the ubuntu installer, I did this anyway, assigning 140 gigs to ubuntu and 500 to windows Now, my computer won't boot into anything but Ubuntu  -in Gparted, it still shows that I have two partitions, and windows 7 boot loader -However, I can't boot into the non-linux partition, and boot loader says I need a recovery disk.  My question is does anyone know if what I've done is fixable? I'm hoping that I can fix it using the way outlined in this thread:   Thanks for the help everyone!  Note: gparted shows:    Foudn linux image: /boot/vmlinuz - 3.13.0.30 - generic   Found linitrd image: /boot/initrd.img - 3.13.0 - 30 - generic   Found linux image: /boot/vmlinuz - 3.13.0 - 24 generic   Found  initrd image: /boot/initrd.img - 3.13.0 - 24- generic   memtest   memtest   Found windows 7 (loader) on /dev/sda1
