    Do you have the Premium Windows installation disk?

    If so, then when you get to the screen where you choose the target partition, click on 'advanced' and delete all the partitions and then create a new single partition with all the space allocated to it.

    The installer will create an extra 'System' partition.

    Format will occur automatically.

    Continue with the Install process.

    If you can't get to that screen, then you may have to use 3rd party partitioning software to delete the old partitions and to create a new one.

    Hope this helps.

    I have a question. apparently my motherboard has 100mb of flash (EFI partition)? What happens if I get rid of it? Can I get rid of it? thanks.
  4. No, that's space utilised by the system and you should leave it alone.

    Did Windows install?

    It says I have a MBR reserved 128mb partiition, What do I do with that?
  6. I'm not sure where you are.

    Did you get to the screen where you can choose the target partition?

    And did you delete ALL the partitions?

    By ALL of them I mean ALL of them.

    There may be three to delete.

    Did you follow the instructions I set out above?

    There are 3 partitions. 1 is 100 mb efi, 2 is 128 mb MSR and the other one is my SSD. I can't figure out how to delete them.

    Click on the 'Advanced' button on the right. This will open up other buttons. One of them is 'Delete'.

    Select each partition in turn from largest to smallest and click on delete each time.

    When the three partitions have been deleted, click on 'Create'. And follow the instructions I posted above.
