Pardon me for my ignorance, but as a new Linux user, I honestly know little to nothing about these things. I'm trying to set up an MBR install for Arch alongside Windows 8, though it doesn't make much sense to me. I'm using this ( https://wiki.archlinux.org/index.php/Grub#Install_to_440-byte_MBR_boot_code_region ) URL to see how it's done, but I'm not sure on a few things.
1) Do I install GRUB beforehand when using the MBR tutorial area.
2) Where and how do I create the .cfg file for GRUB
3) Will it wipe my current Win8 installation
4) Which SDA am I choosing to enter the data for? The Arch install, the Windows install, or what? (The step I'm reffering to is '# grub-install --recheck /dev/sda' )
And, before someone says it, don't tell me to use a different distro. My heart is set on Arch, and I acknowledge the steep learning curve I'm undertaking by installing and using it. (Also, my crumby laptop can't run Ubuntu and other stuff seamlessly, and a barebones OS seems nice, as well as heavily modable)
