I have a pentium IV with 512 MB ram and 80 GB HDD.
I first installed windows XP on the first primary partition, then Solaris on the second with 20 GB for the solaris partition, and when rebooted , the grub menu functioned as expected giving me the options to dual boot, so next I wanted to install red hat with /boot in the 3rd primary partition and / in 1st logical drive of the extended partition and swap in the 2nd logical drive. So, I went ahead and installed linux...but when I went to the disk druid partition manager, the partition manager erraneously showed the solaris partition (2nd fdisk partition) as ext3... but still I went ahead and installed linux as I mentioned above and I told to install the linux grub in the /boot partition.(3rd partition) so that it wont affect the solaris grub. But when i rebooted the system after linux installation, the solaris grub asks me the boot options(windows or solaris?) , but when I select solaris, it immediately reboots and the same rebooting process occurs each time after the grub menu comes...but when i select windows, it works fine....Why is this so...? any idea.. please..
