Reinstall Windows without affecting boot record
I have a new Dell Inspiron 1545 with a dual-boot setup: Kubuntu and Windows 7. A long, tedious story made short, I have Kubuntu working but cannot for the life of me get the wireless adapter to work in Windows 7. Since the Microsoft universal fix consists of reinstalling the OS, that's what I plan to do.
That said, I'm concerned that Windows will not just reinstall itself, but wipe out the boot record used by grub. I've invested enough time setting up Kubuntu that I really don't want to start from scratch (again) with both OSs.
Can anyone provide any tips on how to reinstall Windows without wiping the boot record? If not (i.e. Windows will kill whatever grub has in place), is there a way to use the Kubuntu disc, or another linux disc, to reinstall grub afterward, thereby leaving the linux partitions intact?
Thanks for any suggestions!
