I have seen where several other MacBook Pro owners where able to install Vista with minimal problems. Helping me just boot to the disc would be tremendious. Everytime I boot to the Vista RC1 Install disc, I receive the ACPI Blue Screen referencing non-compliant BIOS. I know the MacBook Pro doesn't use BIOS and runs of off EFI, however, I have seen in several forums where deleting the EFI partition was not necessary in order to complete the Vista install. Any suggestions so that I can at least boot to the disc would be most helpful. BTW...I am not able to boot to the Vista Disc using Parallels either...same ACPI BSOD. Burn a new disc maybe? Has any one else had this problem???
