i am attempting to install ubuntu 12.10 on a machine in dual boot with windows 8. the machine has two hard disks – each about 2TB in size. i install windows 8 on /dev/sda and this works fine – windows 8 boots up and i can do everything on it ok.
then i put in the ubuntu 12.10 live cd and go to install ubuntu. i am presented with the following options for installing ubuntu:
and i choose
something else then click continue. the following screen comes up:
when i click the dropdown box it shows me the following options:
/dev/mapper/isw_bjchifhafj_Volume0 Linux device-mapper (mirror) (2.0 TB) /dev/mapper/isw_bjchifhafj_Volume0p1 Linux device-mapper (linear) (367.0 MB) /dev/mapper/isw_bjchifhafj_Volume0p1 Windows 8 (loader) /dev/sda
/dev/mapper/isw_bjchifhafj_Volume0p1 Linux device-mapper (linear) (367.0 MB) for the boot loader. i then highlight
/dev/mapper/isw_bjchifhafj_Volume0 in the list of devices and click
new partition table. this automatically creates the free space shown highlighted in the above picture.
i then doubleclick on the free space and set the
ext4, set the size to 381MB, and set the mount point as
/. it whinges about not having swap-space, but since i cannot figure out how to further partition the drive i just click
it then starts installing linux and immediately dies. i can't remember what the error was but it just wiped my windows installation completely from the hard drive. what did i do wrong?
