MS works hard to keep Win7 off of HD's, and even when its done it runs like a dog.

Unplug the external and all other drives and peripherals, Boot into Win7 installer System Recovery Options to open a Command Line, confirm the 100mb System Reserved partition (preferred if you have it) or C is Partition Marked Active and then run Startup Repair - Run 3 Separate Times

Is the System Reserved partition marked Active? Partition - Mark as Active (Method Two)

Once you confirm it's set Active then boot into the Win7 installation Media or System Repair Disk to run Startup Repair - Run 3 Separate Times .

If you need help on any set click the blue link to read how to do it.

Ask back if you have any specific questions.

If after confirming Active partition the OS still doesn't show up for repair, from the System Recovery Options open a Command Prompt, type:

bootrec /fixboot
Bootrec /fixmbr

Then try Startup REpair again up to 3 separate times to see if it will repair.

If this fails, start at the top to work through the steps for Troubleshooting Windows 7 Failure to Start.

Everything that can be done to start unbootable Win7 is there, leading up to if necessary rescuiing your files to the external HD to do the superior Clean Reinstall - Factory OEM Windows 7

Those do not sound like any kind of backup of a system image or files which would be useful.

What about the steps I gave you? Are you performing them now? Why not?

you seem to know a lot of stuff wondered if you could help me

im trying to clone my windows 7 on to a sshd drive that is currently in a caddy waiting to be detected but the laptop can't see it. i went in to the manager on c drive and it's there, but doesn't give any options for formatting . i need it to be recognized on plug in so I can run the software and get it plugged in place of my other drive. This is doing my head in. Please help if you can.

How is the drive plugged into laptop? It may need to be plugged in internally. Can you apply the image connected via external HD using a boot disk to the target machine?
