How To Repair Your Operating System


A Repair Install will replace the system files with the files on the XP CD used for the Repair Install. It will leave your applications and settings intact, but Windows updates will need to be reapplied. Here is how to run an OS Repair using the Operating System CD in XP, Vista, or 7:


Windows XP

1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.
2. When you see the "Welcome To Setup" screen, you will see the options below:

3. Press ENTER to start the Windows Setup.
4. Accept the License Agreement and Windows will search for existing Windows installations.
5. Select the XP installation you want to repair from the list and press R to start the repair. If Repair is not one of the options, END setup.
6. Setup will copy the necessary files to the hard drive and reboot. Do not press any key to boot from CD when the message appears. Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.


Windows Vista

If you have a Windows Vista installation disc, you need to restart (boot) your computer using the installation disc. If you do not restart your computer from the disc, the option to repair your computer will not appear.

Here is a step by step picture guide.

If you have a Windows Vista installation disc:

1. Insert the installation disc.
2. Restart your computer.
3. Click the Start button, click the arrow next to the Lock button, and then click Restart.
4. If prompted, press any key to start Windows from the installation disc.


Windows 7

1. If a startup problem is detected, Startup Repair will start automatically and try to fix the problem.
2. If the problem is severe enough that Startup Repair doesn't start on its own and you can't access the System Recovery Options menu on your computer's hard disk, you can get to the menu and start Startup Repair by using the Windows installation disc or a system repair disc that you created earlier.

Toshiba portege 2000 windows xp invalid system disk.


When booting, try going to the Boot Menu by pressing F12 when you see the Toshiba logo so you can select your hard drive as your boot device. After doing so, if you still get an "Invalid System Disc" error, then your hard drive may be shot.

How to reformat..?


These steps are for formatting your primary drive (normally C:\) in Windows 2000, XP, Vista, and Windows 7 and to reinstall the operating system.

The easiest way to format your computer is by locating your operating system CD. Look for a CD or DVD that specifically says "Operating System" or "System Restore". Insert the installation disc into your CD or DVD drive.

Restart your computer.

When your computer is restarting, you will be prompted to "Press any key to boot from CD". Simply press any button on your keyboard when you see this message. If you do not see this message when you restart your computer, you may need to reset your boot disk sequence. *

*To reset the boot sequence, go into BIOS mode. To do this, restart your computer and while restarting press the F1, F2, F10, or maybe the delete key (your computer screen will say "To enter setup press xxx". You only have a few seconds to press the correct key, so if you miss it you will need to restart your computer and try again. Once you have successfully entered the BIOS mode, look for your boot sequence options. Set the CD ROM drive to be the 1st in the boot sequence. Save your changes and exit.

The CD will load a blue screen, then after a few minutes will ask you to press Enter to set up Windows.

You will then be prompted to select where to install Windows. There will be a box on the lower half of your screen that will either show "Unpartitioned space xxxMB" or will have "Partitioned space xxxMB". Highlight which partition you wish to format (typically it will be the unpartitioned space or the space with the largest partition by most megabytes). Hit Enter after selecting the space to partition.

The next step is to choose which file system to format the drive with. The NTFS option will be the fastest option. For most formatting purposes, choose the option that ends in "Quick". Press Enter when done.

The computer will then begin the formatting process. This process may take a while depending on the size of the hard drive you are formatting and the speed of hard drive.

As soon as the drive has been formatted, the operating system files will be copied to the hard drive and the operating system will start installing.

My MacBook is showing a file with a question mark when I start it. And it won't start. I have a feeling that it's completely crashed, but I'm wondering if I'm still able to get my pictures, iTunes and...


Flashing question mark means that the Mac cannot find the operating system due to corruption of the hard drive or system boot up files. Install your original install disc 1 and press and hold down C to boot from disc. Then go into the disk utilities folder. Then click on your hard drive in the left box, and then click on repair disk permissions. Does it boot now? No?? Hook up to another mac by firewire to your computer. Then press power on your computer and hold option key while powering on the other computer. The other computer's hard drive should show up on your laptop screen. Select it and then press the right arrow. Then you can drag and drop your files into the other computer. Get you a new hard drive and re-install the operating system.

STARTING COMPUTER SCREEN SHOWS INVALID SYSTEM DISC


can you get into the BIOS? if so, change your boot order to cd-rom first.

Computer shows invalid system disc,wont let me do anything else


This might be simple.
Assuming your son didn't make any internal changes to your computer. The problem may be that he changed your boot sequence to boot to floppy or CD instead of the Hard Drive.
Do the following:

As your computer is starting you will briefly have the option to hit F8 (I think F8 Might be another) for "start up menu or options".
This will take you to a screen of text where following the on screen text areas and moving the curser with the keyboard arrows and enter or escape check your boot sequence (the order of where your computer is to look for start up information)

It should read as follows:
#1 HDD1 (this text may vary)
#2 CDROM drive
#3 FLOPPY (if you have one) or other removable drive

If your son changed this and forgot to it back your computer may be trying to get start up information from a CD or Floppy instead of your hard drive.

Once you've changed this (assuming you needed to change it) following the instructions use the key to "save changes and exit"
Your computer should now boot up correctly.

Let me know if this helps
