BleepingComputer.com: Can't boot into Windows Vista, Windows 7 or Ubuntu

Okay so yeah. I've got a little issue.

I'm having trouble booting into any OS. I've got Vista, W7 and Ubuntu installed, and I can't boot into any of them.

I can get the Grub menu up, the Windows bootloader menu up, but it won't boot into any of them.

When I try to boot into Ubuntu: the orange bar under the Ubuntu logo goes back and forth, and then it stops and goes to some strange screen saying it's doing error checking etc. It does this forever and doesn't do anything.

When I try to boot into Windows Vista, it just sits on the Windows loading screen with "© Microsoft Corporation" at the bottom and the green bar going across the screen. Does that forever, then the screen goes blank. Does nothing more.

When I try to boot into Windows 7, it first asks me to do the Windows boot repair thingy, so I do that. It sits there, does that forever, doesn't do anything. When I bypass the boot repair and go directly to boot, it does the exact same thing as Vista.

Right now I can only boot into the Ubuntu Live CD. For a time I could access my NTFS partitions on the Live CD, but now it says it can't mount them due to an unclean shut down... I can access my Ubuntu partition though.

What would be the problem? How can I fix it?

Seems to be strange that all 3 of the operating systems decide to just die at once... it worked one minute, I go to work, come back, can't boot. :'(

How do you boot? Does the GRUB come first, then the Windows stuff launches from it? If so, then the Linux forums are probably a better place to start with this. Here's a link to them: http://www.bleepingcomputer.com/forums/forum11.html

It boots into Grub, then to get into Windows I select Windows bootloader then it brings up Windows Vista and Windows 7.

I'll repost this there too.
