At the present time, Solaris installation will overwrite your MBR. You can edit and use your /boot/grub/menu.lst file in Solaris to add chainloader(s) to boot into Windows (already created) and Linux (to be created by you).
But if you want to keep your Linux version of the GRUB, one of the easiest tricks that I have been using is to follow the following procedure: 1. While in Linux & before installing Solaris, edit the /boot/grub/menu.lst file to add a chainloader to the partition in which Solaris is to be installed, title Solaris root (hd0,2) chainloader +1 (the above entry assumes that Solaris is to be installed into the third primary partition) 2. Copy the Master Boot Record to a particular directory in your USB stick (say, /media/usb/mbr_linux): # dd if=/dev/sda of=/media/usb/mbr_linux bs=512 count=1 3. After installing and booting into Solaris, copy this file back to MBR: # dd if=/media/usb/mbrsuse of=/dev/sda bs=512 count=1 4. Do a reboot, the Ubuntu GRUB boot screen will show up, you can then boot into either Solaris or Ubuntu (or Windows). > Thank you for reading my post. > > I was wondering if any member of this forum can help > me with the following query: > > I have an Intel system (desktop) with three HDDs > having dual-boot configuration...with Windows 2003 > Server on the first hard-disk, Ubuntu Linux on the > second & third HD being blank as of now.
