Hello folks,

I am wondering If I can install three Operating system on the same machine.

Currently I have fedora 16 and windows 7, can I install RHEL6 or RHEL7 (64 bit) over the fedora 16 (32 bit) & windows 7 (64bit)?

Please I need your advise whether I can or I can't! and also I want to avoid any grub rescue.

With a "traditional" MSDOS partition table, you can install up to 4 different operating systems in parallel, since most of them can only boot from a primary partition; newer computers come with GPT, where this limitation shouldn't apply, but I'm not sure how mature the tools' support is. Provided you have the space, there shouldn't be any problems - unless the installer fails to correctly recognize the other operating systems. You could first make a full image of your disk to an external USB harddisk using something like Clonezilla (just to be sure you have a way to restore everything as it was), and simply try it.
