After my kids have played with imac ( REVa A 233 - 384 MB RAM -
1st partitions of 6MB  OS 10.2.8 & 9.2.2
2nd partition of 19MB with )OS 8.6 and data files

it stalled at boot up at the blue screen ( after loading  all its stuff)
 disk utility said missing files or wrong order or something like that.
Start up from 8.6 and 9.2.2 are both okay.

so as suggested ran Diskwarrior, and created new system folder - initially there were lots of folder/ files out of whack

after diskwarrior had booted in up into OS X , did a restart to see if all okay, but it stalled at the blue screen again

did an archive and install of OS 10.2 booted okay, on restart the blue screen again
Ran diskwarrior, and  did another 10.2 archive and install
all to no avail ( and disk is full now)

Last night I moved my files over to the other partition and did a clean install of 10.2 - great works a treat
reinstalled 9.2.1 - great works a treat

now to upgrade to 10.2.8 from a disk image - not allowed

tried 10.2.6 combo upgrade from disk image - proceeded okay- complete stall at 4 minutes to go

restart blue - screen again


bugger


now what?

ps i also have a 10.2.3 update disk but stalled whilst running teh installer as well.


any suggestion on cause, workaround, how to correct?
