Dual Booting SUSE/Ubuntu

[fleamour]

Is it possible to dual boot openSUSE & Ubuntu through GRUB 2? Apparently SUSE uses standard GRUB. I installed SUSE but only have Ubuntu options displayed on boot.

I have RedHat, Ubuntu, SUSE and windows 7 on my machine so its possible & also my boot loader is GRUB 2. Even if u install SUSE at the end it should not give a problem coz whatever the bootloader is , its job is to show to entries from the 4 "16 bytes portion of MBR".

Donno why ur system is behaving differently.

Well the SUSE installer is more complicated & less user friendly then Ubuntu's. Will have another go.

I boot from 2nd dedicated Linux HDD from F11 pop up menu at POST because Windows 7 is not GRUB friendly. AFAIK I installed SUSE GRUB to 2nd HDD's MBR rather than 1st HDD where Windows resides.

I set up equal partitions for "/" & "/home" for both Ubuntu & SUSE sharing swap:

Disk /dev/sdb: 500.1 GB, 500107862016 bytes

Partition table entries are not in disk order

I think all was needed was:

sudo update-grub
