Windows is boot looping.

I'm not really sure what this is, but I'll try to provide as much detail as possible.

About two years ago or so I set up a dual boot (Ubuntu and Windows) just for fun. I enjoyed messing around with Ubuntu because I thought it was fresh and new to me. That doesn't have anything to do with the looping though (I think), it installed successfully and I never had any problems.

On one particular day, I'm not too sure what happened to my computer but I couldn't get on Windows anymore. It was in a continuous boot loop and I wasn't sure what to do. I attempted recovering Windows with a CD but it stopped at 99% (I left it there for two days plugged in).

The strange thing, however, is that my Ubuntu partition works perfectly fine. Additionally, I can still access all of my files on the Windows partition from Ubuntu. So I suppose things could be worse.

However, because I only attributed about 30GB of space to the Ubuntu partition, I have limited space to work with and I'm unsure of how to give more space to the partition. As well, a lot of the programs that I used on a daily basis on Windows doesn't work on Ubuntu, or crawls with Wine to a point where it's not worth it. I'm starting to think that I need to get Windows back, but with the boot loop I'm not sure what I should do. So I guess my question is what exactly should I do?

Thanks for the help.

Mark Win7 partition or it's 100mb System Rserved (preferred if you have it) Partition Active,

then run Startup Repair - Run 3 Separate Times until Win7 starts and is marked System Active.

You can then add Linux following Dual boot Ubuntu-Win7

To add space to any partition from any other partition or empty space, no matter if they're adjacent or not, follow How to extend partition easily with Partition Wizard - video help.

If Win7 fails to start and you have GRUB1 then you may need to wipe the hard drive of all code to get Win7 back, as we saw here almost daily during GRUB1. Otherwise the above should work or everything else possible is here for Troubleshooting Windows 7 Failure to Start
