i want to install unbuntu on a second drive since im new to linux and still rely on windows. I know that on "installation type" im supposed to choose "somthing else" then install on /dev/sdb/ but thats not the case for me. i have 13 options all saying almost the same thing /dev/maapper/isw_dicaidicid_volume0 and /dev/maapper/isw_dicaidicid_volume0p(1-4)

I will link a picture to what it says http://imgur.com/a/8GD3p

additional info: i have 2 harddrives 1) 552gb and 388 used and 2) 368gb and 0kb used (the one i want to install unbuntu on)

my computer is a msi gt60

I can't help you with your specific problem, but maybe a little background info can help you solve it. /dev/mapper contains all device nodes created by "device mapper", a tool that is used to have a particular operation performed on block devices. Typical examples are De- and encryption of partitions or management of FakeRAID. If you have FakeRAID enabled in BIOS, you of course cannot switch it off without reinstalling Windows. Nevertheless, as long as it's not RAID 0 (or any other striping RAID) Linux will work fine on it. If it's RAID 0, you have to put he /boot partition somewhere else. –  soulsource Jul 27 '13 at 15:59
    
If this is the case for you, read the (sadly outdated) help.ubuntu.com/community/FakeRaidHowto –  soulsource Jul 27 '13 at 15:59
    
i am in raid 0. i dont know what you mean bu putting the /boot partition somwhere else, cant i just switch raids? i read the link you gave me as i understand from the 10.4 installation /dev/mapper is /dev/sda and that i need to install grub sure but there are 13 different options i can install to. I am totally confused –  Robert Jul 27 '13 at 16:47
    
Actually, /dev/mapper is just a folder. It's supposed to contain a file for every disk and partition that is part of FakeRAID. So, the "file" corresponding to /dev/sda should be /dev/mapper/isw_dicaidicad_Volume0 and the partitions are /dev/mapper/isw_dicaidicad_Volume0p? Afaik the bootloader cannot load kernel images from striping partitions, this is why I said that the /boot partition shouldn't be on RAID 0. Why your second drive is not shown at all, I honestly don't know... The last time I used FakeRAID was 2010 with RAID 1, and no additional drives... –  soulsource Jul 27 '13 at 17:23
    
Okay fine screw installing on the second drive all I want to do is install Ubuntu with windows 7 but I can't since there is no option to install along side windows 7. Ideas? –  Robert Jul 27 '13 at 18:04
