    You need to edit your boot menu to add Windows 7 and Redhat 5.

    provide more details.

    show the contents of your grub config file:
    Code:
    cat /etc/grub.conf
    show the disk automount config file:
    Code:
    cat /etc/fstab
    show what hard drives are attached:
    Code:
    ls -d /sys/block/sd*
    for each disk found (above), list the partition table:
    Code:
    fdisk -l /dev/sda
    fdisk -l /dev/sdb
    etc.

    Windows bootloaders are backward compatible. Your installation was backward and you should always install the most recent release of windows (windows 7 in your case) after an earlier version. If you had installed windows 7 after xp, you probably would have had entries for both in your boot menu.

    It may be possible to manually configure xp to boot windows 7, don't know. I would suggest searching for "boot windows 7 from xp" or something similar or go to the support.microsoft site and search.

    You could check this link, the section which says Method Two.

    Dual Boot Installation with Windows 7 and XP - Windows 7 Forums

    Probably the easiest thing to do would be to use your windows 7 disk to repair the mbr as I expect your xp install overwrote the windows 7 files. There's an explanation of that on the page above.

    Hard lesson: all Windows OS's assume you only want their system, and overwrite the master boot record. This destroys all access to the other OS's. Always install Windows first, THEN install other OS's.

    Download & install Easy BCD 2.0 on your XP, this has the means to restore your Win 7 bootloader & also allows you to manually edit it (for example change 'Earlier version of Windows ' to 'Windows XP Professional'). After that, download 'SuperGrub' and run on CD or floppy to boot back into your main Linux OS. From there, in a terminal, run 'sudo update-grub' and this will restore your GrUB bootloader.

    This, however, assumes you are using GrUB2.

    True that the Windows installs will rewrite the MBR of the disk that is why I follow this procedure when installing multiple OSes:

    1 - Install XP or other Windows OS

    2 - Install Linux - I usually Add Windows to GRUB menu.

    3 - make a backup of the GRUB mbr Stage 1a?
    dd if=/dev/sda count=1 of=/media/MyUSB or wherever is convenient.
    4 - I'll add that copy of the GRUB mbr to the boot manager of Windows.
    For XP just copy the file to C:\ then add a line to boot.ini like so:

    [boot loader]
    timeout=0
    default=multi(0)disk(0)rdisk(0)partition(2)\WINDOW S
    [operating systems]
    multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Micro soft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer
    C:\GRUB-mbr="GRUB Boot Menu

    Here I named the file GRUB-mbr.
    This way if Windows clobbers GRUB and has you booting into Windows instead you can select the second option which will put you right back into GRUB. After that you can restore grub buy simply mount the XP partion like so:

    /dev/mnt/WinXP

    then use dd

    dd if=/dev/WinXP/GRUB-mbr of=/dev/sda

    I'm assuming the sda is the drive your using.

    The problem is that "Windows XP" took over the Master Boot Record (MBR). XP and before assumed that it was the only bootable entry on a machine and takes over the MBR which loses the others. You will need to boot a "Live Linux" system, and resinstall grub (on the MBR) and then create the needed grub entries for all the installed systems. Good Luck.
