For some reason a random data drive "Clear 2" is marked Active which is risky. Mark it Inactive now: Partition - Mark as Inactive - Windows 7 Forums. Only the partition intended to boot an OS should be marked Active.
With separate hard drives what works best is to install with all other drives unplugged, then boot them independently via the BIOS by setting preferred as first to boot and then triggering the other using the one-time BIOS Boot menu key which every PC has.
Presently Win7 drive is marked System so we know it is booting itself.
What I would do is use the BIOS Boot menu to trigger the Windows 8 drive, see if it will boot on its own. We cannot know this until it is booted since the System flag will not show on it's System Reserved partition until it is booted. If it will boot on its own and has its own System flag then install EasyBCD to add Ubuntu as discussed in Dual boot Ubuntu-Win7.
If Windows 8 will not boot on its own, unplug all other hard drives to run Windows 8 Automatic Repair until it does.
I would then boot back into Win7 and use EasyBCD to delete the other OS's so that it is only bootable via the BIOS. If this is not to your liking, add Win7 using EasyBCD from WIndows 8 with Windows 8 drive set first to boot in BIOS setup.
Are you aware that you're using ugly Win2000 Classic graphics in Win7 which has the most elegant Aero graphics of any OS ever that uses no additional resources to render these? May I suggest that you enable an Aero theme in Control Panel>Personalize, then pick a Backgrounds slideshow. The entire collection of Win7 national edition backgrounds slideshows are 120 of the most lavish scenic pictures ever taken and available for download in my tutorial Clean Reinstall Windows 7.
