Clubbing partitions...

This Is My partition Table....

/dev/sda1 (FAT32)  lba
/dev/sda2 (NTFS)
/dev/sda3 - extended --- boot
       /dev/sda5 (ext3)
       /dev/sda6 (NTFS)
       /dev/sda7 (NTFS)

i want to merge sda1 and sda 7 and format them to a single ntfs partition, and set sda2 (which contains Windows 7) as the default operating system for GRUB... How do I do that... I using SuSE 11.2 in sda5.

Thanks.
