After numerous searches on how to setup CentOS 6.3 and Win7 to dual  
boot I turn to the readers of this forum for help...

I suppose my question is quite simple:

What is the correct way to set up a dual boot system for CentOS 6.3,  
or SL 6.3, and Windows 7?

I have tried several times, with several variations, but run into the  
same problem: After installing Win7, then CentOS, the machine boots  
straight into Win7 and no grub menu appears...

I have a pretty new system that I built in Nov 2012: i5-2500K,  
Gigabyte GA-Z68XP-UD3 mobo, 8GB RAM, eVGA NVIDIA GTX 560 card, and two  
1 TB SATA drives.

My first attempt was to install Win7 on drive 0 then install CentOS on  
drive 1, with grub installed in the /boot partition which was on  
/dev/sdb1. Apparently there were some issues with this due to Win7,  
UEFI, etc. I didn't really understand all these problems so I tried  
again.

My second attempt was to try to disable the EFI stuff in BIOS and  
install WinXP, then install Win7 over this to avoid the system restore  
partition, and EFI issues etc. then install CentOS over this, again  
installing grub to /boot, which was /dev/sdb1.

I noticed the default location for grub was /dev/sda, which is the  
windows disk... Would this not hose up the windows install?

I have set up Windows/CentOS dual booting before, but not on this  
machine, and not with CentOS 6.3. Any help would be appreciated more  
than you can imagine...


I have been a CentOS user for a while, but I am intrigued by SL, and  
would definitely jump ship to SL if I can get it dual booting with  
Win7...
