    Why would you mess with WIn7 like that and not have a DVD or System Repair Disk? You'll likely need one to do the repairs if the Repair console i not still on the F8 Advanced boot Tools at boot.

    Boot into Windows 7 DVD System Recovery Options or Windows 7 System Repair Disk to Mark Win7 or it's 100mb System Reserved Partition (preferred if you have it) Active.

    Then run Startup Repair - Run 3 Separate Times until Windows 7 starts and it's boot partition holds the System Active flags.

    If this fails when System Reserved partition is marked Active, move the Active flag to Win7 partition itself and then try the 3 repairs again.

    Be aware that sometimes GRUB can corrupt Windows 7 beyond repair when on the same HD. If problems persist I would delete it completely and then for any future Linux Dual Boots use separate HD's booted only via BIOS, or Dual Boot - Windows 7 and Linux - Windows 7 Forums

    Again, I'd ask at the Ubuntu forums. They would be more familiar with your problem.

    One of those mysteries

    I suspect it is related to the wretched boot partition (that W7 creates, if you let it).

    I always pre-partition my HDDs using GParted and as a result I've never had that boot partition created.
    I've done several triple boot setups since W7 Build 7048 (added HDDs and rearranged the partition layout/sizes) and I've never had that problem occur (GRUB corrupting the bootloader).

    I guess it is one of those mysteries, like how some people say certain programs crash constantly and other people never have any problems with them.

    Interestingly there's been few reports here of GRUB corruption since GRUB2 was released, whereas we woudl see many per week up until then. So I'm close to changing that part of the post template I use for repairing Win7 after Linux removal.

    The Dual Boot tutorial however is brand new and a work of Golden!

    I did make a partition for Ubuntu, however, I think Ubuntu has installed on the same partition as Windows...

    Please post back a screenshot of your maximized Disk Management drive map and listings:

    1. Type Disk Management in Start Search box.
    2. Open Disk Mgmt. window and maximize it.
    3. Type Snipping Tool in Start Search box.
    4. Open Snipping Tool, choose Rectangular Snip, click New, draw a box around full drive map and all listings.
    5, Save Snip, attach using paper clip in Reply Box.

    Tell us what is on each partition.
