multi boot - Have windows 7 and 8 entry options in grub

    I multi-boot windows 7, 8, and ubuntu. I have them each installed on a separate sda partition. I also use a program called "grub customizer" in ubuntu. I need a way to have the windows 7 boot option and window 8 option in grub. Right now there are like 4 ubuntu options (I hid them with Grub Customizer so I only have one), and two windows 8 options (the first one is regular, and the second is recovery, since I installed windows 8 by extracting the iso onto another partition, and ran the installer from windows 7). If I click the first windows 8 option, It takes me to the option booting from windows 7 or 8. For some reason, It shows the windows 7 boot loader rather than the windows 8 metro style one. I also have easybcd if I need to edit any of the options in windows boot manager.

    I just need to add an entry in grub for windows 7, and edit the windows 8 option so it automatically boots to windows 8 (disable boot manager). I don't know how to do this.

    I have windows 7 installed. Then I installed ubuntu 10.04 desktop. The default boot loader was changed into grub boot loader. How do I change it back to default.

    Boot from Windows7-DVD, open the recovery console and type:

    bootrec /fixmbr
bootrec /fixboot

    Then reboot and start from your hard disk. This will recover bootmgr, but there won't be an entry for Ubuntu because bootmgr can only discover Windows automatically. You can use a tool like EasyBCD to change this manually. However I would use grub if there is no specific reason not to do so. You can also try the Windows-Ubuntu-Installer (Wubi). Just insert the Ubuntu-CD while running Windows7 and run wubi.exe. This will install Ubuntu inside your Windows7 partition and add an Ubuntu entry to bootmgr without overwriting it with grub. Then you can remove Ubuntu like any other software on Windows.
