Re: More on win8 please.
any new laptop purchased now is going to come with win8, I'd like to know exactly what evilness MS has in store for those of us who want to dual-boot linux.
Make those restore DVDs as soon as you've unpacked it. Then make another set just in case. Assume that your first attempt at converting it to dual boot will brick it at the software level, and then you can only be pleasantly surprised. (Unless you manage to brick the hardware - far too easy on certain Samsungs, supposedly now fixed in the BIOS. They blamed Linux until someone demonstrated you could also brick one trying to dual-boot two versions of Windows).
Use Google. Read about the generics, and as much about the specifics of your model as possible.
It's probably running in secure boot mode as shipped. This can be turned off, from within Windows 8. I'd recommend that you do. After that you just have to master re-partitioning a UEFI disk, installing Linux into UEFI partitions, and installing Grub2 or other boot manager. Alternatively you can have "fun" trying to install a secure-bootable version of Linux.
The quick and easy way for casual Linux usage is to download free-beer VMware player for Windows and run your Linux inside Windows. (Yes, I know, leaves you feeling unclean just thinking about it. But easy) The other way around requires paying Microsoft more dosh for a retail Windows distribution (or playing fast and loose with your employer's volume license ... which might just cost you your job so don't.)
