    recover GRUB?


    Hi,

    I'm relatively new to Linux administration. I have a dual boot computer using GRUB as a boot manager to boot to Win Vista or Centos 5. It works all right for the moment. I would like to upgrade to Windows 7 and I'm afraid this will mess up with GRUB and I will not be able to boot into Linux. My computer has two hard drive of equal size - I think 500GB. One of them has Windows, the other (part of it) is for Linux.Before I start the upgrade I'd like to be prepared and know how to recover GRUB. Any help in this regard will be very appreciated. Thanks

    Hello and Welcome to the Forums.
    You are correct. Upgrading will overwrite the master boot record and wipe out GRUB in the process. The easiest way to restore GRUB would be to download and burn either Rescatux or Super Grub2 Disk, depending on which version of GRUB CentOS uses, and run that. I think it's GRUB legacy and not GRUB2.
    Super Grub Disk

    Yes, just to confirm - CentOS 5.x uses legacy Grub.

    Arch wiki usually has ace info on Linux in general. Take a look at their GRUB page,
