Hi, I've been trying to install Lion on my PC for about a month and I'm stuck at the same point . My PC runs Windows 7 (partition 1) and iATKOS Snow Leopard (partition 2). Core-2Duo, IDE hard-disk and 2 Gb RAM. I've tried to boot two things: Mac Lion (the official one , not a iATKOS version) from: - DVD: with rBoot, stuck with message "Unable to find driver for platform ACPI" - USB: with Unibeast, it boots but I can't see any disk to select to install (no hard-disk). iATKOS L2 from: - DVD: can't boot and stuck at "Still waiting for root device" - USB: made using Disk-Utility, it boots but I can't see any disk to select except the USB (not hard-disk). As you see... I have tried several things and none of them work . Do you have any idea? Do any of you have the same problem? Thank you!!
