Browsing through this thread it doesnt seem to have one specific reason, but i hope my comment helps someone out there!
I came across this issue for the first time today. I checked this forum but did not find the solution. Here is what worked. After trying to boot to windows 7 in regular mode, the os would not load. I downloaded the file from a third party and saved it onto a thumb drive.
It booted any distro of Linux in any way, shape, or form, concerning the ports and drives it has , but it refused to boot Windows. This is an old issue but since I resolved it for an older system Thinkpad T60 Windows 7 these notes might be helpful and clarify why there seems to be so many possible solutions. This left the basic ATI driver, which works great. Note: before the boot problem, I had another issue, the laptop would always start with LCD in low light mode Hey All, I don't know if there has been a fix to this problem yet but I ran into it tonight.
My computer wouldn't start and showed a black screen. When I tried to boot through safe mode it would hang on the classic classpnp. I tried all the options online such as changing the file name to classpnp. What worked for me was go to the screen where you get to safe mode so rapidly tap f8 on startup.
Then navigate down a few option to "Last known good configuration". I hit this and it worked. This is for microsoft sake but right before I got the classpnp. I selected both automatically fix file system errors and scan for and attempt recovery of bad sectors. When I hit start it said you cannot perform this blah blah because the drive is in use, would you like to perform this on your next reboot?
This is what I believe caused my error. In my case, I was using my laptop and suddendly it froze, so i did a hard shutdown pressing power button for 5 seconds, the next time it will show me 2 options to start normally and to repair the SO. Normal boot ends in blue screen, the repair mode got stuck in finding problems to repair i let it run for 20 hours and never ended. F8 options all ended in blue screen. Then we took out the disk and connected it to a PC, the SO recognized it but the file system shows on windows 7 as RAW, and the data was inaccesible and telling us to format de disk, wich we didn't.
At last we use a software called "HDD Regenerator v1. Restarted de PC and voila the PC recognized the disk and could backup the data. Later we installed the disk on the laptop and SO started flawlessly. Best to get Windows back to Normal mode so you can trouble-shoot the Safemode issues without reloading windows or lossing data or have to reload programs after starting over.
Use the options below to save all kinds of trouble. If you then find the solution to the Safe Mode issue, get back to me here.
NOTE: This was not my suggestion. Another user came up with this but I lost the link to his note. Hi, I just wanted to reiterate another posters answer Just leave the computer alone at the classpnp. It took 1. I assume it was doing a disk repair as the hard disk was busy the whole time. Try to load "last known good configuration" or "safe mode", disable all suspected drivers and reboot, then try to enable it one by one. This way you should find what caused problem. There is complete solution on this site:.
Problem isn't "Classpnp. First, you will need to access "system repair", press F8 on boot, it's usually the first option at the the top. If you can't find it, you can use a Windows 7 repair CD. Instructions are in a previous reply if you don't have one. You'll be stuck on that forever. It should now bring you to the option to get the command screen. Now type, copy AGP Just use the "rename" command to change the AGP The bios had been set to default and disabled this option stopping Windows 7 booting or reinstalling.
I had the freeze constantly at classpnp. I powered on my PC to find it just hanging on the Windows logo during boot. Attempting to go into safe mode it would get stuck at classpnp. After reading some posts, I learned the system is actually getting stuck on cdrom.
This lead me to disconnecting my optical drive and being able to load windows. If I could ask Microsoft's development members a favor, its to change the safe mode boot screen to include the name of the driver its attempting to load next Kinda like Tetris would show you the next block.
Would have made troubleshooting a little easier. Also interesting that the problem related to cdrom. I can't imagine that a subsystem couldn't exist to detect certain failures and move on? At this time I can't say if the failure is hardware or software, but I'm glad I was able to boot and backup files :. I had a similar problem with windows 7.
The system has been running normally for months probably even for years before I came along. Today it hung. Upon reboot it was stuck in a boot loop, it would try to start and then reboot.
Trying to get into safe mode it would hang on classpnp. Upon reading this thread I checked the DVD drive. The light was on and it would not eject.
I powered down ,rebooted and ejected the disk as soon as the power supply was switched on. There was a damaged disk in the drive the silver layer was flaking off. Once I took the disk out it booted up fine. I remember this kind of thing happening back in the old days where a hung or defective device would take down the whole system. I guess the old troubleshooting technique is still a good one to fall back on. Disconnect everything and try booting.
I agree, its a serious flaw in the drivers that a bad device is not detected and disabled during boot. Both in the firmware and the driver there needs to be a bit of sanity applied to the detection process. I guess it WAS eventually detected and a timeout occurred. But it was not handled well. It should not have been a critical failure, but instead thrown an error message and then continued.
SYS boot-loop. I need anyway a new DVD writer just for the sake of installation of new Devices or any new build. Phew, month long pain solved. Office Office Exchange Server. Not an IT pro?

After reading a few threads I read about using Msconfig and checking the safe mode option under "Boot". It still keeps staying at classpnp. I would appreciate and information you guys have that could solve this problem.
If any of you know a command I could type in cmd to bring up the msconfig while in repair mode I could fix it because all I need to do is untick "Safe mode on startup".
Tuesday, March 9, AM. Hello, Try the following resolution: 1. Boot the computer to windows recovery mode. I have tested this step, it will not crash your system.
Any suggestions. This happened to me because I tried to install Fallout 3 too. Tuesday, March 9, PM. Glad to hear tat Fallout 3 is still being played. Firstly there are a few things that I have discovered. As I don't know what your system or brand of computer you are using, I'm not sure exactly what advice to give.
However it should work a little something like this. When you start your computer you will see the brand name of the company who built the system ie. This will bring you to a recovery type menu. From here you can do a system restore you will loose any un-backed up data.
This trick will restore your systems factory defaults systems. I have not been able to try this myself yet. Also depending on your what OS you are using you could try and and get a hold of either the Vista or Windows 7 recovery disks. And the last option short of formatting the drive is to use another piece of software called Ubuntu 9. Put the disk into the drive and but it up during windows start up. You also need to download a replacement classpnp.
I will post with my progress and with what works in the near future. Hope any else can do the same. Wednesday, March 10, AM. My tech knowledge is I know how to turn it on but that's about it, I can tho follow directions if you have any ideas. Thanks You.
