Solved stop error when boot from disk

[Clark Kent]

working on a dell n1050. the hard drive had physically failed. I installed a used one. formatted it thru cmd prmt. now I try to boot the pc from the install disk. it loads files, windows logo, then bsod. stop error: c000021a. I may need to verify the drive got formatted correctly, but otherwise, windows is not installed on this pc. now what?

thanks golden. this is what I'm wanting to do. I insert the disk, boot from dvd drive, it says it's loading the files, the starting windows comes up, then bsod with the stop error.

What type of HDD are you installing too? SSD? How did you format it? DISKPART?

 

[Clark Kent]

I used cmd prompt 'format driveletter: /y', but I think I should chuck it up in my caddy and format it from there. If the drive is really formatted, I should think I would have a different result. The drive was used, but otherwise same in all aspects to match the laptop requirements.

Do the format during Windows 7 installation - see step 6, 7 and 8 in the tutorial

I sure will, if I ever can get to the install now screen. it crashes with the stop error after windows flag starting windows.

During install, at the languages screen, press SHIFT+F10 to open the command window. Run DISKPART, then select that disk and run the CLEAN command.

Now reboot and try install as normal.

What type of install dvd are you using, is it retail, oem, or did you make it yourself ?

Yes, this matters.

c000021a means there's bad sectors on your hard drive.

Run some hard-drive diagnostics and follow these steps:

• Hard Drive Diagnostic Procedure

Find your hard-drive manufacturer and run their tests.

Additional Tests:

• SeaTools for DOS | Seagate
• CrystalDiskInfo - Software - Crystal Dew World

Post a screenshot of Crystal Disk Info summary:

If you have an SSD, make sure the following are up to date:

• SSD firmware
• BIOS Version
• Chipset Drivers
• Hard disk controller drivers/SATA drivers
• If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

Check for any file system errors and bad sectors using Option #2 of:

• http://www.sevenforums.com/tutorials/433-disk-check.html

Use this command with Disk Check:

chkdsk C: /f /r

If your using a SSD, do not run the hard-drive tests on the SSD, check your SSD support page for appropriate testing tools.

Golden, I don't even get to the languages screen. crashes at 'starting windows'. AddRam, I'm using the original install disk for this machine. BlueRobot, I wondered about that. I'm trying a different hard drive now.

Excellent, you are using the process of elimination.

 

[Clark Kent]

you were right. must have been another faulty drive I tried. new one installed, set up continues as normal. thanks for the advice.

Sometimes updating the firmware helps, but we do see a steady stream of bad new SSD's.

You probably are aware that these will always be RMA'd by the manufacturer within the first year. Sometimes it's good to get them involved in testing to set that up.

Thanks for the update, that's good to know
