Is it possible to install linux from my hdd? It refuses to boot off of my dvd drive because it is connected to a raid controller, so booting off of the hard drive is really my only option.
Short answer: yes.
Long answer: at least in theory.
Longer answer: Gentoo allows you to do a network install, so I therefore assume that most other distros can as well.
Other stuff: This page here appears to have some pretty good information that is at least somewhat applicable to your situation (it assumes that you have no optical or floppy drives.) Are you trying to install to a RAID array? If so, you're probably going to have more trouble than just getting to the installation media.
No, Im trying to install to my hdd(pata) from my dvd drive(hooked up to ide raid, with the raid disabled)
Why don't you connect it to the motherboard's IDE port, at least for the duration of installing it?
because there is only one ide port, and thats used by my main hdd. I cant put them in master/slave because my hdd doesnt like that. Alternativly, if you could help me find a driver for linux for the built in raid on my asus p5gd1 that would work.
Your HDD should work fine on the same channel. Did you set the jumpers appropriately?
