I reinstalled Windows 7 on my new HDD, installed Linux over the previous Windows 7 on the old HDD. How do I dual boot?
It seems that I overrided the Windows bootsector in the original HDD that was able to redirect to new HDD where new Windows is.
Do I need to create some kind of Windows bootsector to the new HDD that has an NTFS filesystem, or can I direct the GRUB2 bootloader directly to the HDD that has Windows installed? If so, how do I do it?
Update: This is not a question of how to use GRUB2. It seems that something might be missing in the Windows 7 HDD. I used the Windows installation DVD and its command prompt to set the MBR to the NTFS HDD
bootsect /nt60 all and went from BIOS directly to that HDD. It complained that the disk had no bootloader. I think that even if I set a GRUB chain, it would not work.
