Something happened with my dual-boot OS, It's Windows7, so you may not want to help.

I have a dual-boot Kubuntu 13.04/Windows 7. I rarely use the Windows OS except for a couple of games I own and for dictating speech, but recently, I built a new system. My GPU is a 2gb DDR5 Radeon, and I have been having trouble getting my dual-monitors to work properly.

They work fine using the Windows OS, but I hardly ever use Windows, so I installed my old GForce 460 which solved the problem of dual-monitors on my kubuntu OS. Unfortunately, when I opened the Windows application, the change screwed up the Windows system so much it won't boot without repair.

I did not make the necessary back-ups in Windows, primarily because I knew I would rarely use it and because I did not think an OS just used a few times would have a problem. A stupid error on my part.

Actually, I thought I would be able to recover to a previous time without making a backup. I know so little about the Windows 7 OS.

I have the original installation CD for Windows 7. Can my system be repaired using that? Does it involve complete re-installation of the Windows 7 OS? Sorry to be a trouble for Windows assistance, but I trust Linux advisors over the average Windows specialist. Thanks if you are willing to help?

Like you I'm not particularly experienced with things Microsoft.
This error is probably Windows not having the nVidia drivers.

If I'm correct booting in the Windows install disk will offer the option for a repair, check Google for this function.
But be prepared for losing the Grub bootmanager so after the Win7 repair you will likely have to start a Live session to reinstall Grub.

Sounds like it should work; thanks! I am going to take a respit for a couple of days before attempting your advice. I have been fixing so many things, I need a break. With the exception of the Win7 problem, everything else is working great right now.

I'm sorry, I don't do WinDOHS (anymore, thank God), they done did me enough, lol. I'm sorry, I'm in a goofy mood, I wish I could help ya but...anyway, for what it's worth, HDDs/SSDs are so cheap now, I highly recommend to anybody having dedicated drives for separate OS's.

[tek_heretik]

HD's are these days so large you can easily partition them.
Having your Linux partitions on a separate disk gives no better or greater 'safety', in both cases during install you have to be 100% careful assigning the correct partitions.

There in lies the problem, trusting resizing/partitioning to the installer, no thanks.

if the windows fix didn't wipe the partitions. you shoud be able to use a Super Grub Disk disk to probe for oses and then boot them .after your in kubuntu you might have to reinstall grub or just run the os-prober .. good luck.

next time you might want to try to boot windows in safe mode to you can just change your video driver.
