What other OS's are you running apart from Windows 7? My advice to you would have been to test the Zorin DVD in live mode first. When you see the keyboard and little man you need to press the space bar which should then bring you to Language to use for the OS - automatically set to 'English' - Press Escape key, then F3 to choose input language for keyboard - default is English US - if that is where you live, fine, if UK, use up arrow to select 'English UK' (or UK English - long time since install!).
I would disconnect all your other drives and install Zorin on the blank drive but do it manually - the 'something else' choice at boot menu:
1. Create '/' (root) partition, format to 'ext4' file system of 30 Gb (30720 Mib)
2. Create 'extended partition' and at the END of the drive create 'swap area' that matches the size of your memory.
3. The remaining space left, mark as '/home' and format to 'ext4'
Then install - I always do this from the live desktop and click on the icon 'install to hard drive' to meet the least number of issues.
Now as to Windows 7 issue, once you are in it, create a 'rescue disk' - boot off of that and go to the command prompt and enter:
- Code:
bootrec.exe /FixBoot
followed by
- Code:
bootrec.exe /FixMbr
