How to dual-boot Fedora 14 and Windows 7

These are the partitions and logical volumes created by Anaconda, the Fedora installer. Notice that the first two (primary) partitions, /dev/sda1 and /dev/sda2, are the Windows 7 partitions. Anaconda creates a third primary partition, /dev/sda3, for /boot, and a fourth (extended) partition is initialized for use by LVM, the Linux Logical Volume Manager. Three logical volumes are created, one each for /, swap, and /home.

By looking at the sizes of the logical volumes, and knowing that a new installation of Fedora 14 takes up less than 4 GB of disk space, you can see that the logical volumes sizes can be reduced to free up disk space. After installation, the unallocated space can then be used to create new logical volumes, or grow an existing one. To edit a logical volume, select and click on Edit, or just double-click it.

Default Fedora 14 partitions

The first logical volume chosen for editing is lv_root. The allocated size can be reduced by up to a factor of ten and still have enough disk space to install Fedora 14. The name can be edited to root, from the default of lv_root.

Default root LV

Here is the edited version. Notice the new size and new name. OK.

Edited root LV

Next for editing is lv_swap. I think the default size is just fine. The name, however, I will edit.

Default swap LV

Here is the edited version for swap. OK.

Edited swap LV

The last logical volume to edit is lv_home. As for the previous two logical volumes, only the size and name are going to be edited.

Default /home LV

And the for last time, here is the edited version. OK.

Edited /home LV

With all logical volumes edited, you can see the disk space that has been freed up. That will be used to grow (resize) logical volumes or create new ones if the need arises. Click Next to continue with the rest of the installation.

Free space

If you enabled “Encrypt system,” the installer will prompt you to specify an encryption passphrase. This will be used to encrypt the disk, and will be required to unlock it at every boot up.

Specify disk encryption password

  2. hi
    I have install a linux fedora 13 and dual boot it with windows 7, I have receive the congratulation from linux to install it when the instalation proceces complete, but when I want to choose the linux from my OS options(linux&windows)it dose not run and the pc restart!
    I have install it exactly from your help(these 4 pages).
    what is the problem, and, what should I do?
    with kindest regards

  3. Sir,

    This is a good tutorial… but I have a doubt… I had to install Fedora 14 and I formatted my complete PC (Windows was also removed) and used up all 320 GB for Fedora… Now, Since I have Fedora 14 installed… can I somehow install Windows 7?… Please help me…

    • When dual-booting a Linux distribution and Windows, it is best to install Windows first. Doing that saves you a lot of headaches.

      So my recommendation is backup your data, install Windows, then Fedora.

      If you have another HDD, it is even better to install Windows on the first HDD, then Fedora on the second one. Hope that helps?

      • Sir,

        yes thats an alternative… but installing Fedora and setting up the complete environment for my work… Netbeans My SQL and all took a lot of time and I dont want to do it again… plz if u could suggest smthn…

        • With Fedora already installed, I have to assume that you used all available space on the disk for Fedora, right? If true, that means most of the disk space is under the Volume Group, even if they are not allocated to logical volumes

          With a setup like that, I do not see how you can reclaim disk space from a Volume Group to install another OS. Your two alternatives are, reinstall or get another disk. It’s a tough choice, but that the way it is.

          • hey,

            Thanks for the reply… I think I wud get another disk and install win7… thats the most oblivious choice I shud make 🙂

  4. Thanks for this usefull tutorial. I install fedora 14 on a Dell Inspiron 1520 with windows 7 and work very well. God bless you !

    I am trying to dual boot WindowsXp and Fedora15..For that purpose I partitioned hard disk using Easeus partitioning tool.Here is the partitions from left to right-C drive-primary partition(90GB),unallocated space(11GB),D drive-logical drive(30GB),7GB-primary partition(ESIA),unallocated space-8GB..There are unallocated space of 11GB and 8GB in the system,but when I run the option “Use Free Space” it is showing as no space available..

    • I’m not sure exactly what’s going on, but your partitioning scheme is confusing. It’s probably is confusing to the installer, too. Why the unallocated space between C and D.

      Here’s what I think is a better scheme:

      Since you have three Windows partitions, create them one next to the other, and you can make them all primary if you want. So, you new scheme will be – C (90 GB), D (30 GB), ESIA (7 GB), Unallocated Space.

      When you restart the installation of Fedora and tell it to use the Free Space, it will work. The installer will create an extended partition from the unallocated space, and create all the logical partitions it needs to install the system.

  6. Excellent article – the most helpful guide I have seen so far. I followed the instructions and was able to get the dual boot configured for Fedora 15 and windows 7.

  7. I followed your instructions but didn’t work (I just did not reviewed linux partitions, left as they were), when I boot to fedora I just see a never ending blinking cursor in the top left (but I can boot to Windows 7, of course).

    Maybe because the 3rd partition (Fedora /boot with grub at the beginning) begins after 1 TB? (I think this is the reason)

    Or maybe because it does not work good on a RAID 1 (2 x 2 TB)?

    p1: 100 MB Windows boot
    p2: 1 TB Windows C: drive
    p3: 500 MB /boot
    p4: Fedora LVM


    • I haven’t configured dual-booting on a setup like yours, but the /boot partition starting after 1 TB couldn’t be the reason. There is no technical explanation why that could be.

      The most likely culprit is a checkbox on the Add Entry tab of EasyBCD. When you select “GRUB Legacy” from the Type dropdown menu of that tab, and the partition GRUB was installed in from the Device dropdown menu, you should enable the “GRUB isn’t installed to MBR/bootsector” checkbox. In this article, what I just described could be seen on the first image on this page. That should solve the problem.

      • I had already tried that option 🙁
        News: I booted to Fedora 14 install media rescue mode and tried to reinstall grub, this is the problem:

        grub> root (hd0,2)
        Error 18: Selected cylinder exceeds maximum supported by BIOS

        BIOS is updated, mb is a ASUS P8P67 EVO, problem seems to be the old 1024 cylinders limit (???)

        Could it be a grub 1.x problem? And tx for your support…

      • SOLVED – well to tell the truth I had to surrend, old error = old method. As I suspected the reason was that linux boot partition started too far, I just moved it before Windows 7 partition and now it works.

        – To resume –
        Old situation (ERROR 18):
        p1: 100 MB Windows boot
        p2: 1 TB Windows C: drive
        p3: 500 MB /boot
        p4: Fedora LVM

        New situation (OK)
        p1: 100 MB Windows boot
        p2: 500 MB /boot
        p3: 1 TB Windows C: drive
        p4: Fedora LVM

        and used your method 🙂

        p.s. it works with Fedora 15 too

  8. When i try to install fedora 14 to my 34 gb free space at the time of partitioning the message show tha t”could not mount not enough disk space” , i have 320 gb sata hdd and windows7 home basic

    • 34 GB is more than enough space to install any distro. At the installation methods step, choose the “Create Custom Layout” option. That will take you to the next step so you can see for yourself how much free space the installer is detecting.

  9. i have 500gb hard drive
    c drive 100
    and d drive rest of the space(containing my data)
    i want install fedora 14 by dvd.. (it is not live)
    i am confusing in choosing


    Please suggest me clearly step by step…
    please i tried, i am not getting… please

    • Since you have data on D, first step is back it up. Step 2 is to shrink D to free up space for Fedora. There are two ways to do that – from inside Windows, and from the Fedora installer. Either method will work, but I’ll recommend you do it from inside Windows.

      How? In the Windows menu’s search filed, type partitions. That will launch the disk management tool. Then right-click on D and select “Shrink Volume>” Windows will recommend the save size to shrink the volume to. Unless you know what you are doing, accept it. See example step-by-step screenshots in the “Existing Installation of Windows 7” section here.

      Once that surgical operation is completed, you should see the free space in Windows. Reboot into Fedora installer and when you get to the disk partitioning methods step, select the “Use Free Space” option. Make sure to enable “Review and modify partitioning layout.” That will let you see what the installer has done. How many Windows partitions does the Fedora installer detect? That should do it.

      Let us know how this story ends.

  10. Thanks, you helped me a lot!

  11. This was VERY helpful. I was able to configure my PC for dual boot (into Windows or Fedora) specifically using these instructions. It worked flawlessly. Thanks.

  12. Nothing here is helpful!!!!!!!!! What I am looking for is a way to install Fedora 14 in a partition created specifically for it and then use that as a secondary boot. VMPlayer is a pain in the backside and is only 15% reliable on Windows 7 unless you purchase the full VMWare package. If anyone has any helpful recommendations please reply.

    • I don’t see where VMPlayer or VMWare are even mentioned in the article.

      Anyway, if you could explain a little bit more what you want to achieve, I could be of help.

      • He said, he used a virtual instalation (Fedora loaded in VMware) so he could take screen shots easier. NOT that this is how you load in and run it in a Virtual Machine.

        It’s really easy just do like he said.
