You can see if there is a system restore date in system tools,that goes back before the backup, but not all programmes will reinstall as you have changed the registry

How can you backup and restore the Registry?


Maintaining the Registry

Windows 95
Microsoft included a utility on the Windows 95 CD-ROM that lets you create backups of the Registry on your computer. The Microsoft Configuration Backup program, CFGBACK.EXE, can be found in the \Other\Misc\Cfgback directory on the Windows 95 CD-ROM. This utility lets you create up to nine different backup copies of the Registry, which it stores, with the extension RBK, in your \Windows directory. If your system is set up for multiple users, CFGBACK.EXE won't back up the USER.DAT file.

After you have backed up your Registry, you can copy the RBK file onto a floppy disk for safekeeping. However, to restore from a backup, the RBK file must reside in the \Windows directory. Windows 95 stores the backups in compressed form, which you can then restore only by using the CFGBACK.EXE utility.

Windows 98
Microsoft Windows 98 automatically creates a backup copy of the registry every time Windows starts, in addition to this you can manually create a backup using the Registry Checker utility by running SCANREGW.EXE from Start | Run menu.

What to do if you get a Corrupted Registry
Windows 95, 98 and NT all have a simple registry backup mechanism that is quite reliable, although you should never simply rely on it, remember to always make a backup first!

Windows 95
In the Windows directory there are several hidden files, four of these will be SYSTEM.DAT & USER.DAT, your current registry, and SYSTEM.DA0 & USER.DA0, a backup of your registry. Windows 9x has a nice reature in that every time it appears to start successfully it will copy the registry over these backup files, so just in case something goes wrong can can restore it to a known good state. To restore the registry follow these instruction:
[list=1]
* Click the Start button, and then click Shut Down.

* Click Restart The Computer In MS-DOS Mode, then click Yes.

* Change to your Windows directory. For example, if your Windows directory is c:\windows, you would type the following:

cd c:\windows

* Type the following commands, pressing ENTER after each one. (Note that SYSTEM.DA0 and USER.DA0 contain the number zero.)

attrib -h -r -s system.dat
attrib -h -r -s system.da0
copy system.da0 system.dat
attrib -h -r -s user.dat
attrib -h -r -s user.da0
copy user.da0 user.dat

* Restart your computer.

Following this procedure will restore your registry to its state when you last successfully started your computer.

If all else fails, there is a file on your hard disk named SYSTEM.1ST that was created when Windows 95 was first successfully installed. If necessary you could also change the file attributes of this file from read-only and hidden to archive to copy the file to C:\WINDOWS\SYSTEM.DAT.

Windows NT
On Windows NT you can use either the "Last Known Good" option or RDISK to restore to registry to a stable working configuration.

How can I clean out old data from the Registry?
Although it's possible to manually go through the Registry and delete unwanted entries, Microsoft provides a tool to automate the process, the program is called RegClean. RegClean analyzes Windows Registry keys stored in a common location in the Windows Registry. It finds keys that contain erroneous values, it removes them from the Windows Registry after having recording those entries in the Undo.Reg file.

Diskboot failure insert system disk


What was the problem in the first place? Why are you trying to restore the computer?

Or reading wrong; do you mean the computer will not start? Boot?

Primer:
Disk Boot. -> The bootstrap files on the harddrive.
Bootstrap <- Make it easier to understand?

The basic Windows files.

Can't access restoration on the harddrive with F11? Quite common.
I mean, how crazy is that? Let's put the restoration files, (Basic Windows files), on the harddrive? So if the harddrive goes bad?????

Suggest you use the Restoration Disk.

{Pre-built computer manufacturers were packing the Restoration Disk/s with the computer. As time went by the manufacturers saw the users were not using the disk/s, or loosing them.

Didn't want to use, because of fearing computer damage if they error, or didn't even want to try.

Okay. Put the restoration files on the harddrive, then.
Have the new owner make a BACKUP, when the owner turns the computer on for the first time.
Save a few cents without providing the disk for each computer.
(Take a few cents times 50,000 computers, or more)

Hardly anyone makes a backup disk, when the computer is turned on for the first time. If the harddrive goes bad you cannot access the restoration files.

Computer manufacturers have gone back to packing the restoration disk, with the computer }

What?
Don't have the Restoration Disk? (I won't say anything about not making a backup disk. Could be failure time with it, also)

Go to the back of the computer tower, or up on the side. Write down the Serial Number. It's in the white Service Tag. S/N = Serial Number
(NO, do not post it on the internet. Only to an authorized HP representative)

Call HP Support.
In the USA call 1-800-474-6836
24 hours a day, 7 days a week.
The Restoration Disk is free. The shipping and handling is not.
$17 for a 5 to 7 day ship. $24 for a 2 to 3 day ship.

For other countries use HP Worldwide Support,

Do I think the Restoration Disk will repair the problem?
Dunno. Don't know what the original problem was. You haven't stated it yet.

Emachines t5212 system restore backup files, please help!!


Hello,

If you only your files to be copied in the other or any storage disk then you can remove the hard disk of your machine and then attached it to the other functional machine. in there you can browse and copy all the important files. after copying all your files then you can take back the hard drive to your non functional machine and then install new operating system. documentation found here: http://support.microsoft.com/kb/316941

tell me if something wrong with your system when applying the solution.

File on my computer got erased. I thought it was just a copy of he photos on my Kodak software but now an entire years worth of family photos come's up with lines through it. I don't know how to reconnect...


To avoid losing the file forever, do NOT save any more files on your computer until you can get software from Norton (or another company that makes Undelete software. This software finds and restores files that have been deleted. (Have you checked your Recycle bin to see if your computer just happened to put the deleted file there? If so, you're home free--the file can be easily restored.)

On the other hand, if it's been truly deleted. you have a chance of restoring it with Undelete software. Here's what happens: When a file is deleted, it doesn't really go away. Files are put in boxes called "clusters" and when the file is deleted, the computer puts a mark (such as a "$" sign telling the computer that that cluster or group of clusters can be used for future use. That's why it's so important that you don't ask your computer to file a new file so you avoid the computer possibly overwriting the new file over your old one. If the new file is short and there are several "open" clusters before your photo file, the new file will likely go into one of the sorter, earlier clusters first.

Best luck!

I could not start my Hp pavilion, then I use the restore system by using F11 and start my computer. Now all my files (my document) is gone. How I can recover my files.


f11 takes you to the BIOS/CMOS settup, and a system restore cannot be accomplished there. i suspect you went into the recovery console (notice i said recovery, not restore). in recovery, you have two options, non destructive recovery whitch only reinstalls the factory operating system and keeps your files. it does however changes the location of your files and you have to explore around to find them. a destructive recovery completely rewrites the non-partitioned segment of the hard drive which erases all files.........but............if you have done a backup which stores the files in the partitioned area of the hard drive, you can restore that backup with the back-up and restore utility.

Restoring Files


Is the first of your backup disks a boot-disk?

Often full system backups are restored from a bootable set of disks. There should be a message during startup to press something like F8 to change boot device. You could try using this to see if disk one of your backup is a boot disk & will allow you to restore your files.

Still looking to get my programs out of my back-up files


Generally, U backup data files (word, music, etc) and save the disks that install programs. There are too many "backup" programs to give details on how to operate them. The biggest issue when dealing with backups is that programs have to be installed to the register and many backup programs cannot or will-not reinstall a program to the register.
