How to reinstall my whole OS without having to lose my precious 1080gb memory?

since it looked like the only way that could fix or redo my damaged/messed up/screwed registry was to reinstall the OS. now the current issue isnt that i dont have my win7 64 bit disk but that i dont know a very safe way to keep my beloved memory kept. Now you will probably just say that i can back it up using external drives right? well im kinda broke,ive already spent my every last penny on buying coolermaster v8 CPU cooler and 900 wats corsair power supply on my birthday. so is there anyways to backup exept buying a capacited external drive that ill probably you just once? Just so you know i got 2 drives installed in my rigg,one is capable of holding 148gb (the one where i got my OS installed [although still not sure] and the other 931gb.

I hope my info is usefull for you guys finnaly understand my issues and help me to end this registry boostert crap that been pulled out of the arse once and for all!

If your current OS is still functional, you should be able to partition your drive and do a clean install onto that small portion of hard drive space. I'm not sure if you can partition when you boot from the CD though.

Either way, you're going to have to reinstall programs after you reinstall the OS.

1. format the 148gb HD (cos you say is only OS instalation)

2. reinstal windows

3.????

Im thinking of formatting too. What would you guys say is a good size for the system (win 7 home 64bit) partition? Last time I gave windows 40gb...but now I have only 8gb free, not sure how that happend but thats getting close to preventing me from defragmenting it properly.

oh and i almost forgot. after the time ive bought my windows 7 64 bit copy, ive been ignoring the updates for the whole year. so could an internet windows update overwrite my corupted registries?

I've always cringed when people refer to hard drive space as memory.

Wrong Forum, this should be in Hardware.
