The Compaq SR2020NX has an on-board system recovery tool that can be used to create recovery disks. Unfortunately, on many of these models it was not clearly stated that it was the user's responsibility to create recovery disks, so many people did not do so.
You might be able to launch the onboard system recovery by tapping the F11 key when the computer is starting up. Some of the HP/Compaq models from this time frame allowed that option, but not all of them.
If the F11 key does not work, you will need to purchase a recovery disk set. HP/Compaq no longer sells them for this model, but I did find a link for a place where one can be purchased, which appears to be legitimate. http://www.hpandcompaq.com/index.php?page=shop.product_details&flypage=flypage_images.tpl&product_id=4899&category_id=2&option=com_virtuemart&Itemid=2&vmcchk=1&Itemid=2
1.The first option is you can try to restore it from F11 the hard drive partition...Shut down the comp and then restart it and keep tapping the F11 until you get a screen that says Recovery manager...
2.select the system recovery option if available...click on next...
3.choose whether you want to backup or do recovery without the backup...click on next...
4.Unplugg all external devices apart from keyboard mouse power cable and monitor...
5.then click on the next button...the recovery will start...
6.If this option is not available...disk's are the only option...
reset bios settings, go on and change to factory settings, and try again. if not download hirem boot from http://www.hiren.info/pages/bootcd , burn to cd, reset the pc, put in the cd , seletion boot hirem cd and start some program like hard disc tools and format , then try to install again windows
That depends, what operating system are you using? if its vista or 7 you dont need a disk. Restart the pc and when the bios screen shows press f11 or what ever key is assigned to Recovery Console. Follow the prompts and your all done. If your using xp you may need the disk for the recovery. Have you considered doing a system restore? or is the problem to severe?
When the initial blue HP screen appears, press the F10 key repeatedly until a recovery menu appears. The progress indicator that first appears does not indicate that a recovery is taking place. The progress indicator represents the time before the recovery process is started.
When the Recovery screen appears, click Next, and then click Yes to perform a normal, non-destructive recovery.
To perform a destructive recovery, click Advanced, and then click Yes.
CAUTION: A destructive recovery will format the hard drive. This will delete all the information on the hard drive and reinstall Windows XP and the original software that came with the computer.
After the System Recovery is complete, the computer restarts and continues into Windows setup. Complete the setup screens and wait until the computer finishes the setup.
NOTE: It may take a long time to complete Windows setup. This time varies and may take over an hour, depending on the amount of files that were stored in the user account folders (Like My Documents and the Desktop.
Note:Dont foregt to backup your important files/documents.
Hope this helps !
Insert the HP Recovery Tools CD or Compaq Recovery Tools CD into the CD drive on the computer and restart the computer.Wait for the HP Recovery Tools CD or Compaq Recovery Tools CD window to open.
Select Run Microsoft Recovery Console , click Next , and then follow the onscreen instructions.
If you are unable to open a recovery console, follow the Alternate steps .
Press R to repair the Windows XP installation using Recovery Console.

At the prompt, if the WINDOWS installation you selected in Step 4 was C:\WINDOWS, type:

and then press Enter .
At the prompt, type: exit
Press the Enter key and immediately remove all discs or diskettes from the computer to allow the computer to restart.The error message should be resolved.
These alternate steps work for HP and Compaq desktop PCs with Windows XP and a recovery partition. (M0st HP and Compaq PCs with Windows XP have a recovery partition on the hard disk drive.) These steps do not work if you have replaced the hard disk drive, replaced Windows with another operating system, or repartitioned the recovery partition.You can use the following steps if you are unable to open a recovery console:
Turn on the computer. When the initial logo screen appears, press the F10 key repeatedly until a message about starting recovery appears.
At the Recovery screen, click Advanced Options and then press the Alt and D keys at the same time to go to a command prompt.
At the command prompt, enter the following: diskpart
At the command prompt, enter the following: list volume
Remember the drive letter next to line for the main hard drive; HP_PAVILION or PRESARIO.
To close Diskpart, enter the following: exit
At the command prompt, enter the drive letter followed by a colon (:). For example, H:
At the command prompt, enter the following: cd \windows\system32
At the command prompt, type the following: compact ntldr /u <the drive letter>:\ntldr
For example if the drive letter was H, you would type: compact ntldr /u h:\ntldr
Sometimes, the Recovery Disks are available for download.
But, sometimes, you have to telephone COMPAQ/HP, and give a credit-card number -- they will ship replacement disks for free, but will charge you $20 for shipping.
