[NGCFox]

ody { background: #FFFFFF; margin: 0px; padding: 4px; font-family: Verdana, arial, sans-serif; font-size: 10pt; } Hi there, i downloaded and burnt Kalway 10.5.2 and its booting fine, choosing partitions correctly, then checking the disks integrity fine but as soon as the actual install starts it comes up with an error:

 

The Installer could not create the folder /Volumes/Untitled/BaseSystem.pkg.150rv0YWE

 

then tells me to reboot - ive done this 3 times now

 

i'm lost for what to do, any help would be much appreciated

 

cheers
