I am so frustrated! I have a dual-boot system with Ubuntu 10 (I think) and Windows 7. I don't know why--I hardly ever use Ubuntu. Yesterday, I decided to visit Ubuntu just for a change of pace. I installed some updates, and Ubuntu changed the Bootloader to GRUB! Windows 7 bootloader called GRUB when it needed it. Started them both just fine. Windows won't boot now. It looks like the Vista Bootloader is trying to start, so I presume my computer is trying to run it's original recovery software. It's an HP a6720f that came with Vista installed, and it has a "Factory Image" partition on the HD. It says "Windows is loading files", then a progress indicator, then a blank screen (with lots of flashing from the HD activity light), then a blank screen with a mouse cursor in the middle. After that, no further progress. I've tried to boot into Safe Mode, Last Known Good, Repair, everything. I've tried to boot from both my Windows 7 Repair Disk and my Vista Recovery Disk. Always hangs at the same spot. I'm using Ubuntu now, but I miss Windows! Everything is so hard in Linux! Can anyone help?
