I had to replace a 6Gb HDD in a lime iMac 266. I partitioned the HD and installed the OS, (tried 9.1 and 8.6), and they install fine. upon restart, the drive will not boot. I have checked the jumper and it is set for master. I have changed the partition size from 8Gb to 6Gb to 4Gb and to less than 2Gb. The OS just will not boot.
Any help would be appreciated.

Thanks,
Otter
