Windows 7 Boot up Issues

[GuiltySpark]

Boot up your install or repair disc, select Repair My Computer 


Select the CMD Prompt option.

From this point you are going to have to work out which drive letter has been assigned to your HDD ( note* using a repair or install disc will change the usual assigned letters of drives ), usually D: is assigned as the local drive.

Code:

dir D:

The above allows you to see if your files are contained within the D: drive.

Navigate to \windows\system32\drivers\wrkrn.sys

Code:

D/: cd windows\system32\drivers

Delete the wrkrn.sys file

Code:

Delete wrkrn.sys

When a person is checking a hard drive he or she should always check with two different programs. I see that you did not check with two or more, with that said check its boot order setting, ensuring that it’s set to boot from the correct hard drive.
If the hard drive doesn’t appear in the list at all, it’s possible your hard drive has failed and can no longer be booted from.

Good Day,

I tried to perform the method provided by Brian, however, I get an error that the hard drive is full. I tried going into Kaspersky Rescue disk to delete file but I receive "The trash has reached it's maximum size, cleanup the trash manually". I went into setting and increase the size of the trash folder, when I try and delete now I receive "could not write file /root..........disk full".

I have tried putting the hard drive in an enclosure but the Good computer wants to format the disk.

Any ideas of how to delete some files on this drive. The CBS log files are 25GB, I could free up some space deleting those but it will not allow me to do that.

Thanks again everyone!!

I would check the hard drive health status because it sounds like hard drive failing

Good Day,

Thanks for the info compton. Your method requires that I am able to bootup to Windows. Not possible.

I have ran a Dell diagnostic no issues. I have also ran HD diagnostics using Ultimate boot up disk.. NO errors.

Any other info is appreciated.

Thanks.

You could do it manually via a live cd like Hirens boot cd. and delete data you don't need or boot into Hirens and rename registry hives to .old and then copy backup ones over manually.

Ok,

I freed up 25Gb of space and completed the Restore Registry Hive post from Brian. Thanks Brian.

Unfortunately, I'm still left with the following error at boot up.


File:\windows\system32\drivers\wrkrn.sys

Status:0xc0000098

Windows failed to load because a critical system driver is missing, or corrupt.

Anything else I should try?

Thanks again everyone.

Hi Mike,

First of this is a bad error to resolve. It's very difficult to fix via a forum but I will post some stuff here to help you on your way.

1. Important: Make sure Hard Drive is in good health or any other hardware.
2. Important: Make sure you have a backup of all your data.
   

Options are running out for you I am afraid and after these last fix's I post I think you're going to have to do a fresh install. 

1. Boot to a Windows CD 
2. Insert the Windows 10 bootable installation DVD or USB and restart your PC. (You will need to change boot order)
3. When prompted Press any key to continue to boot from CD or USB.
4. Click Repair your computer.
5. Click Troubleshoot.
6. Click Advanced options.
7. Click System Restore (No Restore Point?) continue. 
8. Automatic Repair /  Startup Repairs (Once complete Restart PC)
9. Still NOT working? Navigate back to Advanced options.
10. Click Command Prompt 
11. Type commands below and hit enter after each one
    

• bootrec.exe /FixMbr
• bootrec.exe /FixBoot
• bootrec.exe /RebuildBcd 
  

If they were not successful please try these below

• bcdedit /export C:\BCD_Backup
• c:
• cd boot
• attrib bcd -s -h -r
• ren c:\boot\bcd bcd.old
• bootrec /RebuildBcd
• Restart your PC
  

Still having problems? Boot back to Advanced options.

• Open Commpand Prompt
• DISM /Online /Cleanup-Image /RestoreHealth
  

If the command above doesn't work please try these below

• Dism /Image:C:\offline /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows
• Dism /Online /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows /LimitAccess
  

If this doesn't solve your issue with what we have already tried its time to reinstall Windows.

hope this helps and let us know how you get on.  Good luck.

Thanks Brian for the information.
