I have two Hard drives's in my system a SATA Drive Raptor 74 GB and a Western Digital 250gb IDE on primary.
Installed Win XP on My SATA Drive and Trying to install Vista on my WesternDigi 250gb in a dual boot configuration.
As I install Vista I get the following Error message below.
"Windows cannot install required files. Make sure all files required for installation are available, and restart the installation.Error code 0x8007045D"
