    Removing win7 from dual boot


    I have win7 and 8 dual boot. However, as I had win7 for some time and have been installing and uninstalling all sorts of apps, my registry got filled up, although i have 92 and 94% free hdds memory. Therefore win7 is very slow.

    Win8 however starts within seconds, opens anything the moment its told to open, in general processes huge ammount of data without all unnecessay services and processes. Therefore, I no longer have a need to have win7 on my computer.

    How can I remove win7 from the computer?

    Install EasyBCD on Win8, then make the Win8 partition the bootable one, delete the entry to Win7, reboot and format the old Win7 partition. This should work

    In addition, another method which should work is to use msconfig to remove the bootloader entry (Windows Key & R to open the run dialogue and type in msconfig and click OK)

    Once msconfig is open, Select the Boot Tab, Highlight and select the Windows 7 bootloader in the boot options and click the Delete button.

    Which ever method you choose to use, once the bootloader is removed then you can format the Windows 7 partition to free up space, just ensure any data is backed up first!

    when you start your computer press delete until the bios setup opens. then go to 'boot' tab (if you have a phoenix bios) then select 'harddrive disks' and select that disc that you prefer as the primary hard disk. (if the hard disc is fat32 bios might think that it's a usb device, so select hard drive as the primary boot device.

    No, I don't have tabs. It offers menu, like a list. I have some kind of intelligent tweaker, advanced cmos settings, advanced bios settings,...

    You can use the Disc management function from within windows. To access this, open a command prompt (Windows key & R) and type in diskmgmt.msc and hit the OK button. From here you should see all your hard drives and partitions in your computer and manage them from here.

    Does the partition next to Win8 partition say "unallocated", if not delete again.
