It sounds like it doesn't know what the Default OS is,You have to get in to Safe Mode and then tell it in the boot manager which one it is.I am not sure ,but I think by pressing F2 or the Del button, it will get you in to Safe Mode,if I am wrong I am sure someone wont be long telling us.

Don't know if this will help, but when i had an XP and a 7 partition on 1 disk I got a disk error after resizing partitions on my laptop; I decided to go into Ubunut live CD and back up all my file onto an external HD and then just reformat the whole drive, wiping it all (after backing up) and making two fresh NTFS partitions using Gparted. I found that when i re-installed both my OS' they both worked, but it is quite a hassel reinstalling everything. but maybe as a last option?

Well that is good that you got to the window that gives you an option ,try different drives to try and start it ,you might find the right drive that the boot is on.

If you get in to your system it would be no harm to run this. SFC /SCANNOW Command - System File Checker

You could also try booting from the Windows 7 DVD & instead of selecting the repair option there should be an option for advanced repair which includes, Startup Repair, Command Prompt (or very similar), System Restore & some others.

If you choose Command Prompt then you should be able to then type various commands. There should be 1 or 2 to do with the MBR (master boot record), i'll post shortly with the list of the commands that are available.

Thanks for all your replies folks,

I seem to have sorted things out. I think GParted got my 2 HDDs reversed.
Both my windows installs were on a different disk to the one I was trying to boot from.
I went into BIOS and moved the HDD order and that got me to completing my Vista new install.
I'm in Vista now. I have an old windows file and I'm trying to get some of my stuff back from that.
Vista is acting strangely though. It keeps refusing to install things that I had on before such as Firefox addons.
Most importantly it won't install the driver for my wonderful Roccat Kone mouse. Luckily I have an old MS one.
I no longer have a boot choice for W7 so I'm formatting that partition.
Hopefully reinstalling W7 will get my boot choice back.
Any thoughts on that?

What a mess. I've been at this all day. Someone said GParted was idiot proof!
Perhaps I am worse than an idiot.
Oh well.

Thanks to you all again, John

Looks from your partition info that you are missing the Windows 7 boot partition at the beginning of the disk, it should be 100 or 200 MB. Can you create a partition at the beginning of the disk of at least 100 MB and run the Windows 7 DVD repair it should copy all needed files into this partition. After you reboot it may need to run the repair option 1 more time to finish, reboot and you should be good to boot into Windows 7.

Thanks Loki. I've reformatted the partition but it appears to be at the end of the disk-about 100GB.
My previous W7 partition was in the same place. Do you think it matters?
I was intending to boot from my W7 disk and custom install on that partition.
Hopefully that'll get my boot choice back.
What do you think?
Cheers, John

The Windows 7 system partition can be at the end of the drive but the boot partition has to be at the beginning of the drive. Or the system partition needs to begin in a bootable section of the hard disk.

Windows 7 creates 2 partitions when you do a clean install. One Boot partition of 200 MB (build 7000) or a 100 MB (later builds) that is at the beginning of the drive, the 2 partition is the system (OS, User) and would be either the rest of the disk or the size selected when installing. Seven needs the small 100 MB (yes megabyte) for booting. If you do an upgrade from Vista, Seven will not create the small partition and keeps everything on the system partition. If you have this small boot partition than anytime you are in the repair mode this will be the "C" drive even if not the "C" in Windows and your OS would most likely be the "D"
