Windows 7: Problems in booting up

Problems in booting up

Hi, to be honest my computer probably has a serious problem. When I try to start up Windows normally, I type in my password for the user account and then it just freezes, it doesn't load. So I think, okay, I'll just try to start up it in Safe Mode, no problem. But when I try to start it in Safe Mode the computer freezes at classpnp.sys and doesn't continue. I'm at a loss about what to do (not that computer savvy, so plain terminology please)


My computer is a Gateway Desktop, running Windows 7 Home Premium (64bit), intel premium processor, 1 TB hard drive, 6 GB DDR3 memory.

I tried using the "Last Known Good Config" option, to no avail. I got the "Replacing invalid security ID" message. I let that go for about an hour when I stopped it, as it was going nowhere.

If it makes any difference, I have also installed another operating system (Ubuntu).

Have you tried using System Restore with the Recovery Disk?

Wouldn't that erase all my files? I need them.

Also, before I ran the Startup Repair that windows comes with, my Ubuntu install wouldn't work either. After it finished, Ubuntu worked fine.

Before Startup Repair, trying to open safe mode would freeze at classpnp.sys, and trying to start Windows normally would result it in rebooting automatically.

After Startup Repair, in safe mode I got past the classpnp.sys and showed me that bloated stretched mouse cursor we all associate with safemode, but there was a black screen and safe mode wouldn't start. Windows did the same thing; it no longer restarted automatically, but I was stuck at a black screen with the mouse cursor after the windows logo showed up.

I'm not sure if that's progress or not, or if it would be any help, but I need to try that. I also attempted accessing my Windows files through Ubuntu, but got an error message.

GRUB bootloader can corrupt Windows 7 beyond Repair when on the same HD. We see it every day here.

Try booting the Windows 7 DVD Repair console or REpair CD to run Startup Repair after marking Windows 7 partition Active. Partition - Mark as Active (Method Two)
System Repair Disc - Create

You can also use free Partition Wizard bootable CD to have a GUI to mark Windows 7 active, then click on the HD to highlight it, from Disk tab select Rebuild MBR, Apply, restart. This may preclude the necessity of running the 3 Repairs.

If it fails, copy out your files using method in post above, reinstall 7 to another HD booted via BIOS if possible, or follow these methods: Dual boot Ubuntu-Win7
