single hard disk, windows 7 is installed on drive C -- primary
drive F -- logical partition, windows xp installed.
drive G -- logical partition, newly created for installing solaris 11, ntfs system.
solaris live dvd was used to install solaris 11, during the installation, I selected the drive G to install the system, and change the partition from ntfs to solaris2.
However, when reboot, no operating systems can be detected, no grub, no bootloader whatsoever.
I looked into another similar thread in this forum with similar problem, and boot the system up using the Live DVD, and ran command like: installgrub -mf /boot/grub/stage1 etc, etc, but the problem is under /boot/grub folder there are no stage1 or stage2 files.
Later on, I downloaded the GParted 0.11 Live CD, and repartitioned drive G as linux-swap (formated as well), and reinstalled solaris 11 on this partition, no luck at all.
a little bit progress so far, I reinstalled solaris 11 again using live dvd, this time I reduced size of the linux-swap partition a little bit, at the same time I can see there is another 'unused' partition been created, when reboot, there is still no bootable devices detected, but the help of live dvd, I can choose 'boot from hard disk' option when booting from live dvd, and now the grub is up and running, the solaris 11 and windows 7 and window xp are all the grub menu list.
Without the booting from live dvd, just boot from hard disk alone, there will no grub whatsoever again.
