I am a Linux noobie, so I apologise in advance for the gaping holes in my computer knowledge.

I have managed to install Fedora 16 Design on my computer which has two physical drives. And I have also made them Raid 0 during the install process. I have a worry where I might come across a hard drive failure because effectively I have doubled my chances of this. I back up everything onto an Ubuntu laptop religiously because of this worry. I have tried to re-install the operating system (F16) and managed to do it where there is just one drive used but then the other drive is not visible at all. I did this because my goal was to have Fedora on one drive and Win7 on the other. Win 7 does not like to install over a drive that had previously been set up with Raid 0. There's a feature in Win7 install which 'Format's' drive. All it did was screw up the grubloader and I had no way of booting Fedora (which had been working fine). So I reverted to re-installing F16 but again I have picked the wrong Raid options and have both of them paired in Raid 0. Doh!

Here's my question - Is it a matter of reinstalling F16 but just picking one disk? If so then how do I get the other hard drive so it can a) be seen by F16 and b) then it should allow a Win7 install.

Please remember I am a noobie - so take it easy!

If you install Fedora on one HDD, you can always mount the other HDD once you're in Fedora. You should be able to set it to auto mount etc too once in Fedora.

To see all disks, some suggestions:

fdisk -l
parted -l
palimpsest (gnome-disk-utility)

I would not advise raid0 for a "n00bie" like you call yourself. The speed win is in most of the cases not worth the risk.

Best is always to install windows first and then any linux. Because Windows can not handle grub and will neither create another bootmenu to allow other OSses to boot. There is a way to do it the other way, but that involves creating a new mbr for a windows boot(just a windows repair would do that, no format needed) and reinstalling grub in the mbr to settle everything afterwards.

And like Francisco_d says you can during the linux install, set the windows partition to mount to a directory of your choice, when you boot linux afterwards.

Otherwise try afterwards a tool like palimpsest (disks in the gnome application search) to have agraphical overview of your disks and partitions and their mount points. (if you like CLI better, you can use fdisk -l.)

Have a look in /etc/fstab to see how other partitions are mounted
