lazydog: I have created a bootable iso, boots OK, I seem to be able to create a new partition to run alongside 7 (for now) but whenever I try to install i get "no root file system is defined". I have checked online but I am not finding things too helpful.
Lin545: You are not installing Linux. You are trying to learn how to dual boot.
Pick a dedicated hard disk and enjoy. You can do multi-boot, but don't claim Linux is hard, because you had to. Windows does not multiboot properly with other OS anyway.
Let me just compare the knowledge needed for dedicated Linux install versus multiboot Linux install.
To compare just how deep you'll have to dive:
Dedicated:
[ ] nothing
Multboot:
[x] filesystems
[x] partitioning (4k alignment, shifting partitions etc)
[x] backing up partitions
[x] bootloader knowledge
[x] mounting, mount points, fstab, /etc/mtab
[x] windows specific problems with multi-boot
Otherwise Windows will do all kinds of crazy things when installed after Linux. That's been my experience, at least.
